Abstract: This study is a synthesis of the existing data overall chorology of the species Carex curvula at a European level, with emphasis of its location in the Carpathian Mountains. As an endemic European species, Carex curvula has a limited distribution - the alpine belt of the main mountains of the European alpine system: Alps, Pyrenees, French Central Massif, Carpathians and a part of the highest mountains in the Balkans. In the Carpathians, it's well known in the Meridional Carpathians (Tarcu, Godeanu, Retezat, Parang, Cibin, Capatanii, Fagaras, Iezer-Papusa, Piatra Craiului and Bucegi Mountains) and in the Oriental Carpathians (Rodna Mountains and Cernogora Mountains). Some older reports from Suhard, Calimani and Ciucas Mountains are considered non-valid for the Carpathian chorology of this species.

Abstract: The paper reports the presence of Stipa dasyphylla (Lindem.) Trautv. in two new sites in Transylvania (Romania). The habitat type and plant communities in which the species occurs are described. The associations in which S. dasyphylla was identified are Stipetum pulcherrimae Soo 1942 (at Cheia, Cluj county) and Danthonio alpinae-Stipetum stenophyllae Ghisa 1941 (in the Turda Gorge, Cluj county). The distribution of this species in Romania is also analyzed and discussed. So far, it was mentioned only from 6 localities. The present study reveals that two sites (Murfatlar and Valenii de Sus) given in previous works may be considered as uncertain.

Abstract: Jovibarba heuffelii (Schott) A. Love & D. Love is a perennial monocarpic crassulacean, having hexamerous flowers, with yellow(ish) petals and ciliated leaves, glabrescent or glandular hairy on both sides. The species is a characteristic carpato-balcanic (dacian) element, with a range spanning between 18-27 degree East meridians. In Romania it is distributed throughout the country, showing wide ecological amplitude, the species inhabiting preponderantly dryer habitats in higher rocky locations. The region involved in our study spans North of Danube being limited approximately by the North 46 degree parallel to the North, comprising a wide variety of habitats from the Danube flood plains to the highest peaks in the Romanian Carpathian Mountains (an altitude ranging between 50-2550 m a.s.l.), with a climate and edaphic conditions similarly diverse. Our study presents a more precise distribution list of the locations from which Jovibarba heuffelii was mentioned and a grid map in the UTM projection system of the species distribution in Southern Carpathian Mountains, together with some chorological and ecological considerations with regard to biotic and abiotic factors involved in its distribution.

Abstract: Sedum hispanicum L. is an annual species perenating by sterile shoots, with subsesile 6-9-merous flowers, with white petals sometimes striated with pink-purplish and glaucous leaves, glabrous or glandular hairy. The species has a South-East-European distribution, being native to the South of the continent with a range limited by the 6 and 38 degree East meridians, but is naturalized in northern regions of Europe. The Romanian range covers the whole country, preponderantly in higher regions, the species occupying with predilection dryer habitats in stony places but having a fairly large ecological amplitude. The region involved in our study spans North of Danube being limited approximately by the North 46 degree parallel to the North, comprising a wide variety of habitats from the Danube flood plains to the highest peaks in the Romanian Carpathian Mountains (an altitude ranging between 50-2550 m a.s.l.), with a climate and edaphic conditions similarly diverse. The present study presents a list of the locations from which the species S. hispanicum L. was mentioned, complemented by a grid map in UTM projection system of the species distribution in Romanian Southern Carpathians together with considerations about the chorology and the ecology of the species with reference to biotic and abiotic factors involved in its distribution.

Abstract: The swamp Ecedea, also known in the Middle Ages by the name 'Lacus Etsedensis', used to occupy an area along the river Crasna, from the town Carei near by the point of its flowing into the Somes river. That was a complex ecosystem, enjoying a wide biodiversity, due to the variation of water pools with sand banks, moors and floating reed islets with water meadows and woods, mezo-hygrophyte to xero-mezophyte meadows with weeds or bushes. Though the area of the swamp was less than 1/10 of what the Danube Delta's area, it enjoyed a wide phytodiversity, which we estimate to about 650 species of cormophytes (which is over 2/3 of the Danube Delta's index of species). On account of bibliographic information as well as personal observation in the area of the former swamp, a list of 254 cormophyte species (hydro-, hygro-, and mezo-hygrophytes) was derived, to which an extra 45 aquatic and marshy vegetal groups are added. Once drained, the swamps were turned into an agricultural zone, of which small areas were temporarily subject to floods (reed). There are 710 cormophyte species in the Ecedea plain, of which 35% are hydrophilous, hygrophilous, and mezo-hygrophilous respectively. Lately, the reconstruction of the Ecedea swamp has been a serious issue, given its continental significance as a wet area. Of the Romanian portion of the former swamp, the most representative parts for a paludal ecosystem are those near the villages Berveni and Capleni. We have focused on the plants and hydrophilous and hygrophilous vegetation outside the village Berveni, more specifically the spot named Bekek, N-NW of Berveni. Here exists typical paludal vegetation with coenoses of associations Phragmitetum australis, Lythro-Calamagrostietum, Schoenoplectetum lacustris, Bolboschoenetum maritimi, Caricetum ripariae, Typhaetum latifoliae, Typhaetum angustifoliae, Calamagrostio-Salicetum cinereae. In the water channels, phytocenoses of Lemnetum minoris, Rorippo-Oenanthetum aquaticae, Glyceretium maximae etc. thrive.

Abstract: The analyzed forest ecosystem renders evident elements of flora and specific phytocenotic structures, that increase the scientific interest and claims for protection, because of its floristic richness and the rarity of many of the species identified among 1935 and 2004 by the botanists: I. Todor, Petruta Pestroiu, St. Sararu, A. Popescu, Bibica Draghici, V. Alexiu. Many of these species are preserved in the herbaristic collections of the Arges County Museum and those of the Pitesti University. Being placed at the border between Cotmeana Platform and the High Plain of Pitesti, the Trivale Forest represents a strong interpenetration of the montane and plain flora. Besides the scientific interest, the Trivale Forest represents the green lung of Pitesti, a strongly industrialized town. An important segment of this forest was transformed in a Park whose age is secular. Conformable to the Decision 18/1994 of The County Council Board, Trivale Forest was declared Forest Reservation of local interest.

Abstract: The present paper represent a contribution to the chorology in Romania of some species, which has been retrived in the upper basin of the Aries River Tayloria tenuis (Dicks.) Schimp. has been identified on dead wood, and Dicranum tauricum Sapjegin and Lescuraea mutabilis (Brid.) Lindb. ex I. Hagen, on beech bark. These three species present poor populations in the studied area. As a result of an inadequate management of the forest, their substrate disappears in many parts of Romania. In addition their distribution in Romania is scattered therefore these species should be considered vulnerable.

Abstract: Preliminary studies on the benthic diatom communities from the Somesu Mare river and its tributaries (Tibles, Rebra, Meles) between Ilva Mica and Beclean (Jud. Bistrita-Nasaud). Algal community structure was studied in 12 sample sites located along the Somesu Mare river and three of his affluents, in April, August and October 2004. There have been identified 255 taxa belonging to 36 genera. Affinities at the level of diatom communities have been tested by cluster analysis using the floristic similarity index of Jaccard. Diatom species have been used to evaluate the saprobic status (Saprobic Index) and the quality of water (Biological Diatom Index) [7] in sampling sites. Based on the SI employed, the upstream water of mountain tributaries (Tibles, Rebra) is o-beta-mesosaprobic, while its downstream water, the Meles river in headwater and the studied sector of Somesul Mare is beta-mesosaprobic. The organic pollution from downstream of river Meles is moderate to strong (beta-alpha-mesosaprobic), according to the method of Zelinka and Marvan (1961). The BDI values is changed from an excellent water quality (upstream of the Rebra river, in spring and upstream of the Somesu Mare river, in autumn) to a lower one (downstream of the Meles river, in autumn).

Abstract: This paper is the first record that documents the qualitative structure of the algal communities inhabiting the creek crossing the Nature Reserve of botanic character - 'Valea Morii' situated in Cluj County, Roumania. There have been identified 114 taxa belonging to the following major groups: Cyanoprokaryota (12 taxa), Rhodophyta (3 taxa), Bacillariophyta (92 taxa) and Chlorophyta (7 taxa). The diatoms are dominant in every season of the year, having their maximum in autumn. The species diversity of communities increases from upstream towards downstream according to the changes of natural local ecological conditions, but also due to human activities like sanitation measures and drainage of the bog, forest clearing, buildings, household waste waters or farming. As such, on a relatively short distance - just a few kilometers, the qualitative composition of the algal communities changes drastically. Upstream 'Valea Morii' creek (sites 1-3) the communities dominated by acidophilous, microthermal, oligo-mesotrophic, xeno-, oligo- or beta- mesosaprobic elements, markedly changed downstream. In sites 4-6 where the human impact is very evident, eutrophic, basiphilic - basibiontic saprophytes, some indicating critical saprobity levels (beta-alpha-, alpha- or polisaprobity) overgrow the community, dominated by cosmopolitan algae.

Abstract: The present paper is the first major contribution to the investigation of the algal communities from some aquatic habitats of the Botanical Garden from Cluj-Napoca. Based on seasonal samplings (spring, summer and autumn), carried out during 2001, from the Tiganilor rivulet and a spring situated nearby, we found that the algal flora exhibits a high diversity, namely 81 taxa much higher than that found in 1999 (38 taxa). In spite of the fact that the natural regeneration process had started and most species are beta-alpha-mesosaprobic, a significant number of polisaprobic ones are still present, denoting a certain pollution stress. As concerning the algal communities, inhabiting the small concrete reservoirs located near the 'Water Tower', they exhibit 194 taxa. The diversity of algal flora reflects the heterogeneity of aquatic habitats of the various reservoirs.

Abstract: This study aimed to estimate the production and productivity of Agrostis capillaris and Festuca rubra grasslands from the Lapusului Mountains (Maramures county), as well as the influence of their different uses on these parameters. Although the results obtained are only guiding, they express both the dynamics of primary productivity and production, and the influence of grazing on the productivity of the analyzed grasslands. Thus, green mass production reaches its highest value in July, after which it decreases, while dry matter production increases over the period of the whole vegetation season. Primary productivity reaches maximum values in June, after which it gradually decreases, and 20% of the species provide approximately 80% of the total phytomass production.

Abstract: This study was designed to determine the extent to which the carbon isotope ratio in four species of lichens was influenced by such features of the natural environmental as humidity and rainfall. The range of d13C measured for the studied lichens was -26.93% to -19.06%, with a mean value of -23.38%. The result of this study was found that of natural factors humidity tended to decrease the value of d13C, and the precipitation to which the lichens were exposed tended to increase d13C. The effects were minor of the order of 1% for all lichens. From their opposite effects, the natural parameters could be assumed to cancel out. We submit that this result is important to the field of the environmental monitoring of pollutants. The outcome of a monitoring study would be only interpretable where the effects of natural environmental factors on a species of lichens were either negligible or systematic.

Abstract: Plant peroxidases, also known as class III peroxidases, are proteins containing a hem fraction, encoded by a large number of paralogous genes which form a numerous multigenic family in higher plants having an expression which is particularly sensitive to internal or external events. Arabidopsis thaliana genome contains 73 genes encoding peroxidases. Exhibiting homologies ranging from 28% to 93% at the nucleotide level, there is a risk of cross-hybridization which may be important when measuring the level of transcripts by blotting techniques, using whole cDNA sequences. We developed a procedure to assess the expression of all peroxidase genes on one membrane, with a high specificity. The method is based on the determination for each gene of a short specific sequence (amplicon) exhibiting at the most 70% homology with any other sequences of the Arabidopsis genome. Amplicons specific for each of the 73 peroxidase genes were blotted on a nylon membrane that was hybridized with radiolabelled cDNA libraries prepared from mRNA of Arabidopsis leaves representing three categories of age, namely young, adult and senescent leaves. Many genes were expressed at a low level, often in leaves of all the three cathegories of age, while some of these genes were strongly expressed. Some genes with no ESTs reported in databases were found to be expressed and this was confirmed by RT-PCR. Isoelectric focusing analysis revealed that the isoperoxidase pattern was generally similar in leaves belonging to different cathegories of age, but it also presented some differences concerning the isoperoxidases bands and those differences could be considered as some new identified isoforms. As far as we know, only one similar study has been performed on the cytochrome P450 family, using microarrays, but this is the first work describing the expression profile of a whole large multigenic family using specific macroarrays.

Abstract: The paper is part of a study comprising the histo-anatomical features of the vegetative organs in some woody climbers. The stem and leaves (except the petiole) of Hedera helix possess specific features in accordance with its climbing nature of Hedera helix. The stem exhibits a secondary structure, thickenings due to the activity of a conventional cambial ring. Cork cambium is also present, initially superficial, forming a cylinder (circular ring in cross section) around the stem. The cortex is extremely reduced, consisting of 3-4 layers of parenchymatous cells. The stele occupies the largest part of the stem. The mechanical tissue is poorly developed and consists of septate fiber bundles in the stem, but it is well developed in the petiole, being represented by collenchymatous cell layers. The stele consists of three collateral vascular bundles. Bundle sheaths are absent in the blade and petiole. The hardness of blade is given by collenchyma cells located in between the middle vein and the two epidermises. A number of calcium oxalate druses are present in both the stem cortex and in the blade (especially around the mid rib vascular bundle). Stellar hairs for the protection of plant are present on the stem surface, petiole and blade. Secretory cavities are present in both stem and blade, but the petioles lack them.

Abstract: Anatomy of Austrocylindropuntia subulata (Muehl.) Backeb. (Cactaceae). Austrocylindropuntia subulata (Muehl.) Backeb. is member of the Cactaceae family, very common in house plants collections. This paper deals with some anatomical aspects of the root, stem and its subulate leaves. The results revealed that the anatomical structure of this plant justify its succulent nature, especially the water storage parenchyma is well developed, forming the largest portion of the stem and mesophyll. The root of this cactus species is well developed, its secondary structure gives special strength to it. The mechanical tissue is absent in the stem. The vascular system of the stele is poorly developed, represented by a number of closed collateral vascular bundles in rhomboidal arrangement. The mesophyll of the subulate leaves is differentiated into palisade tissue and storage parenchyma. The vascular tissue of the leaves is represented by three closed collateral bundles. Remarkable is the presence of some large, isolated, circular lacuna in the stem cortex and in the mesophyll of the subulate leaves.

Abstract: Above all adaptive properties developed under the influence of light can be observed in the structure of the leaf blade. The structure of the above-ground stem is influenced only in an indirect way, for example it defines the level of development of the mechanical tissues. In this thesis there are histo-anatomical studies of the leaf blades and stems of 15 angiosperm species with the application of methods for making microscopically preparations. The studied vegetal material was collected from differently illuminated habitats. The determination of chlorophyll content has been made by applying the spectrophotometric method. The adaptation of the sciophytes and heliophytes leaf blades to light effects can primarily be observed in the structure, the type and in the stage of development of the assimilatory tissue. Total chlorophyll quantity was significantly higher and leaf thickness larger in sciophytes than in heliophytes.

Following results were obtained by HPLC methods (expressed in g compound/100 g vegetal product): G. phaeum L.: 23.91 hyperoside, 932.76 ellagic acid, 8.52 rutoside, 60.51 sinapic acid, 17.63 cichoric acid; G. pratense L.: 180.37 hyperoside, 7195.45 ellagic acid, 75.09 isoquercitrine; G. palustre Torner: 4578.97 ellagic acid, 69.15 isoquercitrine, 67.66 caftaric acid, 67.41 rutoside; G. columbinum L.: 3620.24 ellagic acid, 59.05 isoquercitrine, 19.74 caftaric acid, 159.30 quercitrine; G. dissectum Jusl.: 29.41 isoquercitrine, 51.32 rutoside. Analysing by HPLC means the hydrolised samples we have obtained the following results (expressed in g compound/100 g vegetal product): quercetol (48.72 in G. phaeum L., 165.76 in G. pratense L., 64.87 in G. palustre L., 222.76 in G. columbinum L. and 88.82 in G. dissectum Jusl.) and kaempherol (11.02 in G. phaeum L., 36.83 in G. pratense L., 77.31 in G. palustre L., 12.23 in G. columbinum L. and 9.90 in G. dissectum Jusl.). We have also demonstrated indirectly the presence of ellagic tannins (the amount of ellagic acid increases after hydrolise) and we have showed the probable presence in G. dissectum of polycaffeoil compounds (caffeic acid was identified in amount of 4.27 g/100 mg only in the hydrolised sample).

Abstract: In order to continue our previous phytochemical studies concerning the species Geranium phaeum L. and G. robertianum L. (Geraniaceae), we have analysed by gas chromatography coupled with mass spectrometry two samples of essential oil, extracted using the Neo-Clevenger apparatus, as described in the Romanian Pharmacopoeia Xth Edition. Analyses were performed on a Hewlett-Packard 5890 series II-5972 MSD, the mass spectrograph being tuned using perfluorotributylamine as tuning standard. Following compounds were identified in G. phaeum essential oil: ?-cubebene, sinularene, germacrene-derivatives and germacrene D, ?-humulene, ?-cadinene, viridiflorol and superior hydrocarbons. Following compounds were identified in G. robertianum essential oil: trans-caryophyllene, ?-elemene, germacrene D, germacrone and superior hydrocarbons. These are the first GC-MSD Romanian analyses on the essential oil extracted from Geranium species, previous Romanian studies were performed only by thin layer chromatography and concerned G. macrorrhizum L. essential oil.

Abstract: Using like vitamins (A, E, C) and proteins sources, the Elaeagnus angustifolia L. fruits have a reach composition [1]. After a preliminary chemical study was identified the poliphenolcarboxilic acid (ODP) and flavonoides (flavonosides, proantocianosides, tannins), moreover saccharides and mucilage. The quantitative analysis of ODP and certain flavonoides (flavonosides) was made using the spectrophotometric methods with a Turner apparatus beside caffeic acid and rutoside, like reference substances. The quantitative analysis show a medium contents in flavonoides as 0.13% couched in rutoside and ODP as 0.06% couched in caffeic acid. The antioxidant properties of ODP and flavonoides, known by reference materials [5], make to affirm that the drug could be interesting for capitalization in phytotherapy.

Abstract: The extractive solutions 10% obtaining for flowers and young branches by maceration 8 days in ethanol 10% (A1, respective B1 solutions) and in ethanol 40% (A2, respective B2 solutions) was tested on the Triticum vulgare grains for discovery a some cytotoxic and cytostatics effects of Elaeagnus angustifolia L. species (Elaeagnaceae). The determinations were made beside a witness maintained in water. Was aimed the influence of extractive solutions about germinations and rootlet growing over 5 days. Also, was aimed the alterations about mitosis film generate of the treatment with extractive solutions (A1, A2, B1, B2) at 6 hours and 24 hours interval. Was observed that the Triticum vulgare grains germination is not inhibited of any extractive solutions and the rootlet growing of germinated Triticum vulgare grains in these conditions was late and their aspect was thick and forked. At the finished of the elongation test, the rootlet growing, at the Triticum vulgare grains germinated in water, caused by the A1and B1 solutions (88.5%, respective 69.2%) is grater then the one produce by the A2 and B2 solutions (80.7%, respective 65.3%). Also, the inhibition is most intense at the extractive solutions obtaining by flowers (A1 88.5% and A2 80.7%) then the other obtaining by young branches (B1 69.2% and B2 65.3%). The rootlet aspect is modified beside witness, become thicker and forked, as preceding event. Concerning cellular division the extractive solutions have not citotoxic effects. The only alteration observed is a heterocromatinisation of the genetic material round about nucleus membrane, in prophasis. We believe that the rootlet growing inhibition produce by extractive solutions is caused by flavonoides, compound well-known in reference material for their antiauxinic properties.

Abstract: Microbiological and physico-chemical analyses were carried out on the mine spoils resulted from the mining of iron ore in Iara, Cluj county, in order to establish the toxicity of the spoils. The decreasing order of the metal concentration in the raw spoils is: Fe > Ca > Mg > Cr > Pb > Zn > Cu > Ni. The raw spoils have an alkaline pH and contain only traces of organic matter (3-4 mg/g dry matter spoil). The following 5 ecophysiological bacterial groups have been studied: aerobic mesophilic heterotrophs, ammonifiers, denitrifiers, iron-reducers and desulphofiers. Based on the number of bacteria belonging to each ecophysiological groups, the bacterial indicators of spoil/soil quality (BISQs) were calculated. A strong positive correlation statistically very significant has been established between the BISQ and the organic matter content. Between the most abundant metals (Fe, Ca, Mg, Zn, Cu) on one hand and the BISQ and organic matter, respectively, on the other hand, a negative correlation, statistically very significant was also established. Based on the results obtained, a biological recultivation experiment was initiated on the spoil dump. 26 experimental plots were installed on the spoil dump, submitted to different treatments, and cultivated with herbaceous species. The same microbiological analyses were carried out on the experimental plots for establishing their bacterial potential at the beginning of the recultivation experiment. The number of bacteria decrease in the order: aerobic mesophilic heterotrophs (105-106) > ammonifiers (102-104) > denitrifiers and iron-reducers (102-103) > desulphofiers (101-102 cells/g dry matter spoil/soil). The desulphofiers were present only in 9 plots, all of them covered with soil. The plots covered with soil have higher values of the BISQ than those uncovered.

Abstract: The mycoparasitic fungus Coniothyrium minitans, recorded for the first time in the world from California USA (Campbell, 1947) and in Europe from the Great Britain (Tribe, 1957), is one of the most interesting subject of the biological and agricultural research due to the hyperparasitic action against sclerotium-forming plant pathogens, among them Sclerotinia spp., very dangerous and difficult to be controlled for many cultivated plants. In Romania, this fungus has been recorded by Aurelia Crisan (1986). Then the bio-ecology of the fungus (Sesan, Crisan, 1988, 1998; Sesan, Baicu, 1993a) and the ways of using it as a biocontrol agent for plant protection (Sesan, Csep, 1991-1996; Sesan, Baicu, 1993b, Sesan and colab., 1997) have been studied. It has been reviewed the results concerning the efficacy of bioproducts based on C. minitans under different climatic conditions in Romania in order to protect industrial and medicinal plants as well as pulses against white rot (Sclerotinia sclerotiorum), researches with practical importance in sustainable development of agroecosystems, results connected at the same time with the similar ones performed in the world.

Abstract: The exclusion of organic synthesis chemical products from the organic agriculture involves the necessity to find other kinds of products for pests and diseases control but without diminution of the quality and quantity production. The objective of our research was to test 'in vitro' the influence of some water plant extracts on the apple scab conidia germination and to test the efficiency of some biological products made from Trichoderma harzianum and Bacillus subtilis on the control of rugosis cancer apple trees in the field. The results showed that the majority of water plant extracts totally inhibited Fusicladium dendriticum conidia germination. About the rugosis cancer control made with biological products, the best results were obtained by using, in the same time, two studied species of micro-organisms: Trichoderma harzianum and Bacillus subtilis. It is known that the best products for rugosis cancer control are made from copper, but after the petals fall it is preferred to use some biological products because they do not produce phytotoxicity like the copper products.

Abstract: Soil is doubtless the most complex of all microbial habitats, while the microorganisms are the major participants in this habitat. The technogenic soils represent a special category, where the abiotic components underwent important changes, the same for the microbiotic componence, that is why the study of the relationship soil microorganisms plant may represent an important parameter in the evolution of such, within the biological recultivation. The microorganisms are deeply involved in the mineral nutrition of plants, besides the fact that the synthesis of the humic substances, respectively the mineralization of the organic substances depend both on the soil microbiota and on the nature of the cultivated plants. In the present work we looked for the interactions between microorganisms, soil and plants in the experimental variants of a technogenic soil from Rovinari area, a soil resulted after the surface extraction of lignite and subjected then to biological recultivation. There were studied 6 variants cultivated with different plants. The soil samples were analysed both from microbiological and enzymological point of view. It was followed the presence and the dynamic of the levan-forming bacteria involved in the levan synthesis, an important component for the agregation of the soil particles, that is in the formation of a favourable structure from agronomic point of view, close related to the nature of the cultivated plant. It was also determined the number of levan-decomposing bacteria that hydrolise the levan, the equilibrium of the two physiological groups beeing inclined towards the synthesised ones. An other ecological group of studied microorganisms was the one of molecular nitrogen fixing bacteria, aerobic, non-symbiotic (free) that contributes to the enrichment of the soil in nitrogen and that were directly influenced by the nature of the cultivated plant. It was followed the dehydrogenase actual and potential activity that characterises the proliferating microbiota, from enzymological point of view, direct related with the cultivated plant, with the fertilization system and with the applied agrotechnics. The obtained data highlighted the relations between the ecological groups of studied microorganisms, close related to the enzymological (dehydrogenase) activity and with the nature of the cultivated plant.

Abstract: Aspects of the postglacial vegetation history reflected in the peat bog complex from Dames (Apuseni Mountains). This work presents the results of palynological studies carried out in the peat bog complex from Dames (on the valley of the river Somesul Rece), lying 2 km downstream from the Blajoaia camp, at an altitude of about 1,380 m. In the successive visits to this peat complex we have noticed, in time, the serious human damage caused by the peat exploitation works. In 1978 the peat of the lower peat bog from the left side of the valley had already been under exploitation and it was depleted in a few years. Subsequently, the exploitation of the other peat bogs from the Dames complex has begun. In our last visit (2004), only small areas of peat were left, at the periphery of the peat bogs. The first palynological study of this peat bog was done in 1986 [1]. Our work represents a continuation of this study, attempting to enrich and clarify the vegetation history of the region. The palynological results from a sequence extracted 10 years ago frame this sequence in the late Preboreal, as the configuration of the pollen spectrum from the basal level proves. The dynamics of the vegetation from the region until present time are presented.

Abstract: Palynological analysis of a peat sequence from Zanoaga Rosie III (Semenicului Mountains). This paper presents the results of the palynologycal study carried out in the peat bog area from Semenicului Mountains, near the Semenic Touristic Complex. The region of the Semenicului Mountains from the southwestern part of the Romanian Carpathians have great significance in the improved knowledge and the clearing up of the issues of the glacial refuges for certain woody taxa as well as their migration pathways towards and inside Romania. From the Zanoaga Rosie peat bog, at an altitude of about 1400 m samples have been taken from three sequences with different thickness. For the palynological analyses we have selected sequence number III, with a thickness of 210 cm. In spite of the relatively small thickness of the peat layer caused by the small sedimentation rate, the palynological analysis has emphasized aspects from the evolution of vegetation especially forests- in the area, from Early Preboreal until present time.

Abstract: Deficiencies in the EU Habitats Directive annexes transposed within the Romanian law 462/2001. Developing the Natura 2000 network in Romania is a high priority taking in consideration the EU integration process. The harmonization of legislation with the acquis communautaire is an important step for Natura 2000 implementation. The Habitats Directive was transposed by the law 462/2001 related to natural habitats types and valuable local species for conservation. Due to some methodological errors, the applicability of this law poses some difficulties. Some of the errors are mentioned below: - The annexes I and II of Directive no. 92/43/1992 EEC related to the conservation of natural habitats and wild flora and fauna, were included in law 462 without the required changes to adapt the list to Romanian habitats list and valuable species from Romania. - For level III habitat classification, several criteria were used (altitude, soil humidity, nature of the substrate, type of vegetation, building species, building plant association etc). The result is an overlapping of some units. - When vegetation criteria are used for classification, either one or more building species are used to establish the vegetation type either the building plant association. - An important percentage of building species and some species included on the list with valuable species for conservation have no distribution area in Romania, some of them being endemic for other countries. To conclude, the emendation of the annexes in order to correct all the errors seems to be the optimal solution and the particularities of Romanian vegetation have to be taken in consideration.

Abstract: The history, activity and the destiny of an institution are often mistaken for the lives and virtues of the people who serve it. There are many examples and all confirm the truth by which man elevates the place where he works and offers it a particular characteristic of his own personality that suggestively defines its value and originality. Organized on scientific bases, the Botanical Garden has diversified its functions and purposes, transforming more and more into an active scientific factor. Today, it is not only a school for the formation of students and biology researchers, but also an institution having merits in environment protection, germ plasma preservation, the culture of the rare species of spontaneous flora, and in spreading knowledge on the vegetal world. Alexandru Borza Botanical garden is presented as having an impressive past. The multilateral activity carried on in the Botanical Garden reveals the work and capability of its team, the passion and generosity of the people working here, which shows a clearer and larger perspective. The existence and the role of the botanical gardens will have to be presented in a larger context. The essential part of insuring a future to our planet is the teaching of ecology. For all these, besides the education and information means, the botanical gardens have a great importance. They will have to find ways of modern and effective ecological education by which the people would protect the environment. We think that the role of the Botanical Garden should be that of education and research institution, in the field of botany. Without this part, the botanical garden would become a park or a garden for pleasure, lacking in the vocation and pulsation of scientific life, lacking in that permanent competition impulse that each botanical garden has.

Abstract: The drastic decrease of a great number of plants and animals during the last decades has alarmed the specialists in the biodiversity conservation throughout the world; thus more steps have been taken in order to reduce this phenomenon. New national and international organizations were created, in which medium and long-term strategies were stated, including precise tasks for all the factors involved in the maintenance of the biodiversity. The Association of the Romania's Botanic Gardens, created by the initiative of the Management of the Dimitrie Brandza Botanic Gardens of Bucharest is certainly the most efficient one. Treating indifferently the continuous degradation of the environment due to the activities with negative impact on it represents an action of maximum gravity for the next generations. An important role in the ecologic education belongs to the Botanic gardens. Having an impressionable great number of cultivated plants, lots of educational activities, the botanic gardens offer the visitors the possibility to see the plants, their environmental conditions, what endangers them, and the importance they have for our everyday life. I am presented a series of concrete shares, unfurled to Gradina Botanica from Jibou, in the direction instructions and young educations.
