The management of these areas is carried out with the view of their conservation and sustainable usage of biological resources they generate, according to international and national law's provisions. Wetlands are important for: water regime's adjustment, as floodable spaces, in order to take sudden water flow's increase; microclimate stability; numerous species of plants and animals that find refuge only in these optimum conditions of survival and development; the maintenance of ecologic balance; soil humidity adjustment and erosion diminution; the conservation of aquatic ecosystems' biodiversity, the living place for many plant and animal species; water quality control by means of chemical purifying as well as by decreasing the amount of organic and nutrient substances; flooding mitigation and the decrease of flooding effects; the supply with fresh water for the local communities; an important role in education, research, recreation etc.
Vicose vienna pe picior of the most important ambassadors for nature conservation, Dr. Taking into account the speed with which challenges related to protected areas are both changing and growing, there has never been needed before a human capacity well-trained for managing this fact.
As far as territorial organization of this service is regarded, for a better surveillance, D. The general climate characteristics of The Danube Tratamentul varicelor pediatrice are those temperate-continental, with differences between western and eastern areas induced by the bordering continental influence, respectively the maritime one or between the northern and southern ones with opening to The Russian Plain, respectively The Northern and Central Dobrogea's Plateau.
Generally, the climate of The Danube Delta Biosphere Reserve is determined by the continental, pontic, maritime influences and air in advection Bogdan, The geomorphological particularities low altitude, the relative uniformity, the absence of major orographic obstacles on the way of the main air masses advection and the wide opening towards all wind directions determine common climate features which impose periodic and non-periodic variations to all meteorological elements.
There are also climate influences determined by morpho-hydrographic particularities and those of the zonal vegetal coverage. Locally, the complex topoclimates of the fluvial delta, fluvio- maritime delta and Razim — Sinoe Lake Complex's are developed and a multitude of anthropogenic and natural elementary topoclimates. Climatically, the area of the Danube Delta Biosphere Reserve represents the resultant of the positive extremes' main manifestations: the highest values of solar radiations and, implicitly, of the Sun shining duration; the vicose vienna pe picior air temperature values on Romania's territory; the biggest persistence of clear weather, especially during summer at noon time; Vİİİ the lowest multiannual average amount of precipitations; the largest amount of precipitations fallen within short time intervals 24 and 48 hours ;long intervals with dryness phenomena and climatologic drought on the first three places in the country as frequency, duration and intensity ; high wind frequencies and speed — the highest energetic values in the country; the high intensity of evaporation and evapotranspiration; the increased frequency vicose vienna pe picior intensity of dangerous meteorological phenomena rain and snow downfall, fog, blizzard etc.

They are an important category of primary producers, being both directly and indirectly involved in carrying out the functions of aquatic ecosystems and ecotone areas.
The eutrophication, the geo-morphological modifications or the climate changes are all challenges to which aquatic plants will react differently. To conclude, we wish to point out the importance of the habitat types and for The Danube Delta and to de la castanul varicoza extern attention on the danger of some particular aquatic macrophyte species' expansion, highly competitive under the actual conditions provided by the delta.
The information presented in this chapter does not constitute a red list of The Danube Delta Biosphere Reserve. The aim is to elaborate a compendium on the basis of reference works with a view to facilitate the access, in the field, to information on the sozological status of superior plants conservatively important. Out of the total number of the recorded cormophyte species in DDBR, have been selected, of conservative interest, and 39 considered extinct, not found recently or insufficiently known.
According to some authors Dihoru et Negrean, ; Ciocârlan,the causes of species extinction are anthropogenic, mainly manifested in reduced habitat and important changes in the floristic spectrum, natural causes through the degeneration of some species and the sudden destructive modification of certain climate factors. It is considered that the monitoring of these species evolution needs to be carried out once in 5 years on the basis of the recorded global positioning points in Ciocârlan, Up to present, this type of monitoring has been achieved only for the species conservatively significant at European level, namely: Marsilea quadrifolia, Aldrovanda vesiculosa, Echium maculatum, Centaurea pontica and Centaurea jankae.
Among these, only Centaurea jankae, sub-endemic species for Romania, is considered vicose vienna pe picior stable population. The species considered adventives have not been included even if their status is calatorind pe o trambulina i varicoza or rare.
Among the presented species, from the origin perspective, the Euro-Asiatic ones prevail, followed by the Mediterranean, European, Pontic and Pontic-Mediterranean ones. Under sozological aspect, by comparing information from different years Oltean et al. Locally, there is displayed data with concern to spreading, so that, in the field, the searched species should be looked for within a more restricted perimeter of D.
İX Ch. The knowledge concerning these invasive species thus becomes highly significant, particularly when we have to deal with an internationally protected area such as The Danube Delta. The harbours of Sulina and Tulcea, and also Reni, Ismail and Chilia Ukrainethe last two settled on Vicose vienna pe picior branch, may constitute entering gates for the alohtone species into The Danube Delta, at the same time with goods transported on water.
Tourists may also become, sometimes even involuntarily, vectors for some alohtone plants. How many times, after a trip in the nature, have we noticed fruit or seeds of some plants on us? This is one of the simplest ways that a plant should get from a place to another.
Besides people, animals may represent an important vector for the invasive plants. Within The Danube Delta, we frequently see how cows and horses bear with them, clung in their tails and manes, the fruit of spiny cocklebur. Birds can transport large fragments of plants, seeds, spores for long distances on their claws, beaks or feathers.
On the other hand, it has to be mentioned that wetlands have an increased vulnerability compared to other ecosystems and are susceptible to be invaded both because of the suffered disturbances Pino et al.
The most common landscape unit in this area is represented by reed habitats which cover a surface of about ha, out of which the mono-dominant reeds comprise approximate Hanganu et al.

In The Danube Delta, reed is harvested for roof construction, reed mats, for the manufacturing of thermo-isolating boards in construction business, as material for fence building, fuel, and fodder for animals and matter for the production of cellulose.
Reeds also provide habitat for fish fauna and wildlife, contribute to nutrient absorption from eutrophic waters, to reduce heavy metals concentration and to retain sediments. Reeds are appreciated especially for the bird and mammal variety which depend on this habitat, some of these being threatened or endangered species.
At present, due to the decreased capacities of harvesting, as well as to the difficulty of marketing, the amount of reed harvested in The Danube Delta Biosphere Reserve D. The main problems are those of the reduced harvested or maintained surfaces, with vicose vienna pe picior consequence of Salix cinerea expansion and reed extinction, particularly in the areas with organic soils Matiţa-Merhei, Vătafu - Împuţita and otherswhich cover approximate ha.
At vicose vienna pe picior same time, the rehabilitation vicose vienna pe picior Babina Islet enclosures, 2. The aim of this paper work is to briefly present the acid acetilsalicilic din varicoza of turning into account of reed vicose vienna pe picior in D. As far as the spread is concerned, the species of medicinal interest X occupy important surfaces on the territory of D.
All items of information have been synthesized in a centralized data base displayed in this study through synthetic tables which include information with regard to medicinal herbs species and their harvest amount within every district of D.
For each species, the local name has been mentioned in order to be identified by those who gather and use medicinal herbsthe flourish period with the purpose to gather them at the optimum time — for the species of which they use the flowers and the aerial part Popescu, ; Mohan, and the spread degree which draws attention on the perpetuation threshold of a certain species, particularly for the rare and sporadic ones Ciocârlan, For those who intend to gather and use medicinal herbs, the component parts of the plant containing maximum of active substances, known in plant-pharmacy as drugs flowers, leaves, roots, rhizomes, seeds and fruit, buds, bark or the whole planthave been specified and also the allowed harvest amount in each district and respectively their included cantons.

Crăciun et al. Nevertheless, at vicose vienna pe picior, scientifically, the least studied macro-organisms are the insects. They are indissoluble part of all the food chains, of the energy, information and matter transfer routes within ecosystems and between them, model and determine the presence of various types of ecosystems, are vectors for different diseases, under certain conditions they manifest, due to their gregarious character, impressive invasions varicele varicoase asupra manifestarii picioarelor the list is open.
It needs to be mentioned that the displayed results refer to data which could not comprise all the fauna groups. Inventory data is from the — period. Fauna discoveries obtained during the research years, highly significant zoo-geographically results, justify entirely the necessity to carry on and extend these researches across all the fluvial- maritime sandbanks in the delta, areas that constitute important unpolluted refuges of a fauna diversity rarely met in other places in vicose vienna pe picior country, as well as the vicose vienna pe picior to protect these territories, Letea and Caraorman forests being entirely some of the most important natural monuments in Romania.
The main features of the insect fauna in D. Moreover, there are other 3 species with uncertain situation: black carp Mylopharingodon piceus not acclimatizeda species of ray-finned fish Cobitis megaspila — in the process of scientific acknowledging and the Black Sea shad Alosa maeotica — not captured.
The list of environment factors with effects on either the presence or absence of certain fish species and particularly on their abundance or frequency; the water regime the water presence and level, liability to flooding ; climate temperatures vicose vienna pe picior direct effect, and the wind comandai botori de la varicoza precipitations with indirect effect ; water physic-chemical parameters transparency, colour, dissolved oxygen, pH, water's chemistry — ions ; area's geomorphology water bed relief, soils, silting degree ; anthropogenic influences poaching, overfishing, pollution, embankments etc.
Within this fish fauna chapter, several sea-fish species of commercial, ecologic or protective importance will be presented, for their recognition, such as: commercial, endemic, protected, endangered, rare and exotic species. In the present perimeter of The Danube Delta Biosphere Reserve, 10 native amphibian species and a hybrid have been recorded, respectively 12 local reptile species.
In setting the efficiency of D. Therefore, the monitoring periodic evaluation of the populations belonging to these species present in D. There are also described details related to three simple monitoring methods whose approach by the trained staff of D.
The environmental wardens involved in the monitoring of amphibians and reptiles in D. Providing cameras for the field agents may lead to the increase of information amount supplied by the staff involved in monitoring the pictures are also useful for the experts to taxonomically categorize particular specimens with different features from the usual characteristics of the species they belong to.
The delta is crossed by several important bird-migration routes, which provide an amazing fauna richness, birds being represented by approximate species. In the delta, the ice duck finds shelter camp, coming from beyond the polar circle, the scray nests, which spends the winter in South Africa. The largest European pelican colony is here and an impressive number of small cormorants, yellow-crowned night herons, ibises and spoon-bills, all of which are considered rare in the other European countries.
The tratamentul popular al voalurilor varicoase urzice places in Sfântu Gheorghe and C. Rosetti localities provide shelter for several-cube-metres nests of the last white-tailed eagles. There are also the last few specimens in the country of Danube falcons.

On the littoral, the sand banks and islands provide shelter for the vicose vienna pe picior colonies, camp for ducks and various species of ruffs, knots and plovers, which arrived here in passage.
Ornithological observations provide surprises every year. These are particularly the birds with numerous populations which, due to the important biomass they represent, significantly participate within the matter circuit in the deltaic biom, consuming vicose vienna pe picior and being food for other species. A part of these birds are of game interest, representing the subject of hunting activity geese, ducks, pheasants, rails, pigeons, plover etc.
Some of them are tourist attraction, while others, most of which are endangered, are subjected to special research. Mammal species of communitarian interest from Annex II of the Habitat Directive and respectively the record sheets of Natura in The Danube Delta Reserve are described in this chapter as follows: Lutra lutra otter ; Mustela eversmannii European polecat ; Mustela Xİİ lutreola European minkPhocoena phocoena harbour porpoise ; Tursiops truncatus common bottlenose dolphin ; Spermophilus citellus ground squirrel and Vormela peregusna marbled polecat.
The species are presented in relation with their habitat and food chain. Stomach contents analysis, endo- and ecto-parasites are described also for the basic spreading mechanism identification. Data regarding the conservation status is mentioned in order to enhance the overall importance of mammal species in the protected area. Some conservation measures are indicated for each species with the purpose of local and regional management monitoring, species distribution in relation with their food resource.
The short description of cum de a trata varicoza la stadiul incipient mammal species provided in this chapter combined with climate seasonal changes and anthropogenic impact faulty management, over fishing and hunting, habitat fragmentation can show a general trend of population development to environmental wardens and inspectors involved in habitats protection.
One of the purposes of this chapter is to give a short explanation of diseases spread from domestic to wild animals and to humans at the end by different vectors insects, arthropods, mammals favoured by certain factors anthropogenic, climatic, resilience. Their incidence is higher during the temperature and humidity transition between seasons.
The data of these disease groups is up to date, especially within wetlands, where climate change vicose vienna pe picior have a significant role. Internal complex mechanisms and factors involved in sickness occurrence with spreading tendency must be studied particularly under the conditions provided by the Danube Delta. For an organism to be exposed to aggression caused by bacteria, viruses, parasites or fungi, a series of factors such as pathogenic agent sources, ways and vectors of transmission need to act together, to all these being added the favouring environmental factors which are decisive for the quality of a certain population's health.
The result of all the vicose vienna pe picior abovementioned is that the epidemiologic process is level-structured: sources, ways and vectors, organisms with different receptivity degrees. The connection between knowing the structure and levels of the epidemiologic process, as well as understanding its functioning, is logical for ongoing investigations.
Evaluating and predicting a certain malady evolution are the main vicose vienna pe picior with the purpose to optimize preventing and control activities within the frame of health programmes.
The approach of the epidemiologic process issues imposes the defining of certain elementary notions: epidemic centre, infectious process and infection centre.
The epidemic centre is represented by the space where the pathogenic agent source lies, which can disseminate it with the risk of reaching receptive organisms within the focus area. The infection centre represents the place, the tissue or the organ where the complex interrelationships between pathogenic agents and the organism subjected to their aggression are acting at various degrees of intensity and polymorphism.
The necessary exactness with concern to accuracy of data, analyses and solutions as well as the complexity of approaches, imposed by the occurred issues, supposes the usage of tools that may meet the research requirements. In the present chapter, a few examples will be described, when modern methods and techniques for analysis and environment monitoring have been employed, with the view to increase the efficiency of the management implemented by decision factors, with the support of the scientific community's research and of the local communities as partners.
Xİİİ Ca exemplu, în ultimii ani, inundaţiile catastrofale care au afectat teritoriul românesc au demonstrat vulnerabilitatea noastră la manifestările fenomenului global al schimbărilor climatice.
Efectele lor au arătat necesitatea de a schimba rapid concepţia şi modul de acţiune împotriva calamităţilor naturale cum sunt inundaţiile, seceta sau inversiunile şi variaţiile frecvente ale temperaturilor.
Deşi, la nivel naţional, s-au abordat tot felul de strategii cu perspectivă, la nivel local, gestionarea efectelor schimbărilor climatice s-a dovedit ineficientă. Direcţia şi amploarea schimbărilor climatice la nivel regional, ca şi efectele asupra măsurilor de management, sunt încă neclare.
Vor fi condiţii noi, care vor schimba structura habitatelor, în special în zonele umede, dar şi în alte zone naturale. Habitatele şi speciile sunt considerate ca fiind foarte vulnerabile în raport cu schimbările climatice. Plecând de la această ultimă idee, în Europa centrală cu precădere, au fost demarate o serie proiecte de cercetare care sunt menite să diminueze efectele schimbărilor climatice asupra biodiversităţii.
În urmă cu trei ani, a început, la nivel european, un proiect care a avut în vedere adaptarea măsurilor de conservare a naturii în raport cu schimbările climatice. Cooperarea internaţională a 17 instituţii de cercetare şi 24 de administraţii de arii protejate constituie efortul comun de a reduce şi stopa declinul biodiversităţii raportat la presiunea climatică, efort pe care l-am numit noi HABIT-CHANGE Management adaptativ la modificările induse de schimbările climatice asupra diversităţii habitatelor din ariile protejate.
Institutul Naţional de Cercetare Dezvoltare Delta Dunării, ca partener în acest proiect, şi-a propus să susţină Administraţia Rezervaţiei Biosferei Delta Dunării în selectarea celor mai adecvate măsuri de management, capabile să diminueze efectele schimbărilor climatice asupra florei, vegetaţiei, faunei şi habitatelor.
Aşadar, a fost organizat un seminar în cadrul Institutului Naţional de Cercetare Dezvoltare Delta Dunării, care a avut ca scop instruirea şi informarea agenţilor ecologi şi comisarilor Gărzii de Mediu din Rezervaţia Biosferei Delta Dunării.
Manuale ale rangerilor au mai fost realizate şi pentru alte arii protejate din România, motiv pentru care am considerat oportună iniţierea acţiunii şi în această rezervaţie a biosferei.
Scopul este de oferi informaţii utile despre habitate, floră, faună, schimbări climatice, zoonoze şi aplicaţii în sistemul informaţional geografic. Schimbările climatice reprezintă contextul general la care se aliniază capitolele cărţii.
Fiecare autor de capitol prezintă informaţiile într-o formă cât mai accesibilă, alăturând textului o serie de fotografii, grafice, scheme şi hărţi pentru a înlesni activitatea personalului implicat în munca de teren.
Sperăm că acest manual va îmbogăţi cunoştinţele celor interesaţi şi că va fi un instrument util de lucru în teren. Editorii: Mihai Doroftei şi Silviu Covaliov XİV As an example, in the last years, catastrophic flooding, vicose vienna pe picior affected the Romanian territory, are evidence for our vulnerability to the manifestations of the climate change's global phenomenon.
Their effects have revealed the necessity to rapidly change both the view and way of action against natural calamities such as flooding, drought or frequent variations in temperature. Despite the fact that various types of perspective strategies have been approached at national level, the management of climate change effects has proved inefficient.
The direction and proportions of climate changes at regional level as well as the effects on management measures are still unclear. There will be created new conditions which will trigger changes in habitat structure, particularly within wetlands and other natural areas as well.
Habitats and species are considered to be highly vulnerable in relation with climatic changes. On the basis of this premise, a series of research projects have been started, in Central Europe especially, which are meant to diminish climate change effects on biodiversity.
Three years ago, a project was started at European level, which has had the perspective to adapt measures for nature conservation in relation with climate changes. The Danube Delta National Institute for Research and Development, as a partner in this project, has set the goal to support The Danube Delta Biosphere Reserve's Administration in selecting the most adequate management measures, appropriate to diminish the climate change effects on flora, vegetation, fauna and habitats.
