Pristupanjem međunarodnim konvencijama, BiH/RS se obavezala da će uspostaviti sistem mjera kojim će se omogućiti očuvanje biološke raznovrsnosti i zaštitu autohtonih i ugroženih rasa domaćih životinja. Nepostojanje registra autohtonih rasa sa preciznim podacima o vrsti, brojnom stanju i lokacijama grla, onemogućava preduzimanje mjera zaštite i sprečavanje nelegalnog izvoza, čime se ugrožava njihov opstanak. Zakonska regulativa koja bi regulisala inventarizaciju i zaštitu genofonda još uvijek ne postoji, a u oblasti genetičke raznovrsnosti veoma mali broj naučnih i stručnih radova posvećuje pažnju o autohtonim rasama. Sa aspekta očuvanja animalnih genetičkih resursa potrebno je u što kraćem vremenskom roku predložiti i usvojiti Zakon o genetičkim resursima Republike Srpske, kao i izmjene i dopune Zakona o stočarstvu RS, te donijeti programe i pravilnike koji su od ključne važnosti za upravljanje genetičkim resursima u stočarstvu, a u skladu sa međunarodnim standardima.
Species’ range shifts and local extinctions caused by global change lead to community composition... more Species’ range shifts and local extinctions caused by global change lead to community composition changes. At large spatial scales, ecological barriers, such as biome boundaries, coastlines, elevation, and temperature gradients, can influence a community's ability to shift. Yet, ecological barriers are rarely considered in global change studies, potentially hindering predictions of biodiversity shifts. We used data from two consecutive European breeding bird atlases to calculate the geographic distance and direction between communities in the 1980's and their nearest compositional equivalent in the 2010’s and modelled their response to barriers. The ecological barriers affected both the distance and direction of bird community composition shifts, with coasts and elevation having the strongest influence. Combining ecological barriers and community shift projections can identify ecological corridors that facilitate shifts of species and communities under global change.

Extensions to the breeding range in the late 19th century were potentially aided by the rapid development of managed fish-ponds in eastern Europe, which provided suitable novel habitat at that time. Expansion into western Europe followed in subsequent decades. Wetland and waterbody eutrophication throughout Europe, which likely provided food and cover for the birds, may have accelerated the rapid expansion from the 1950s until the early 1980s. Widespread declines in the last 30 years, especially in eastern Europe, where breeding numbers are highest, are possibly linked to intensification and/or abandonment of freshwater fish farming and changes in water quality. Studies show that Pochard gain fitness benefits from nesting in Black-headed Gull Chroicocephalus ridibundus colonies and has hence been affected by major losses of European gull colonies in th...

We used species distribution models (SDMs) to predict changes in range dynamics for 64 non-passerine wetland birds breeding in Europe, including range size, position of centroid, and margins. We fitted the SDMs with data collected for the first European Breeding Bird Atlas and climate and land-use data to predict distributional changes over a century (the 1970s–2070s). The predicted annual changes were then compared to observed annual changes in range size and range centroid over a time period of 30 years using data from the second European Breeding Bird Atlas. Our models successfully predicted ca. 75% of the 64 bird species to contract their breeding range in the future, while the remaining species (mostly southerly breeding species) were predicted to expand their breeding ranges northward. The northern margins of southerly species and souther...

The extent, however, to which climate change has driven recent range shifts alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years to explore the putative drivers of recent range dynamics, considering the effects of climate, land cover, other environmental variables, and species’ traits on the probability of local colonisation and extinction. On average, species shifted their ranges by 2.4 km/year. These shifts, however, were significantly different from expectations due to changing climate and land cover. We found that local colonisation and extinction events were influenced primarily by initial climate conditions and by species’ range traits. By contrast, changes in climate suitability over the period were less important. This highlights the limitations of using only climate and land cover when ...

Tokom ljeta 2015. i 2016. godine proučavana je fauna ptica duž rijeka Sutjeske iHrčavke, te na pet glacijalnih jezera. Ukupno je registrovano 78 vrsta ptica, od čega je 9 vrsta novih zanacionalni park. Od ukupno do danas registrovanih 118 vrsta, 108 su moguće, vjerovatne ili potvrđenegnjezdarice parka, a najznačajnije moguće, vjerovatne ili potvrđene gnjezdarice zabilježene u toku ovogistraživanja su dnevne grabljivice (Pernis apivorus, Circaetus gallicus, Aquila pennata, Aquila chrysaetos,Falco peregrinus), zatim prdavac (Crex crex), polojka (Actitis hypoleucos), od sova buljina (Bubo bubo), aod djetlića indikator očuvanih planinskih šuma, planinski djetlić (Dendrocopos leucotos).

During the study period a total of 101 species were identified. The study recorded some interesting species, such as Spoonbill (Platalea leucorodia), Black Stork (Ciconia nigra), Red-crested Pochard (Netta rufina) and Ferruginous Duck (Aythia nyroca). This, together with a rather high total number of species identified, indicates the area is important for some endangered bird species. The study also recorded various negative effects of the humans on birds. Uvod Koliko je poznato, u oblasti Modriče ranije nisu vršena detaljnija ornitološka istraživanja. Ranija bilježenja pojedinih vrsta na širem području opštine Modriča odnose se jedino na usputne bilješke o sinantropnim vrstama poput Columba livia domestica, Passer domesticus, Corvus monedula, Corvus frugilegus i dr. u okviru faunističkih istraživanja Bosne i Hercegovine (Mikuška et al., 2005), te na pojedine rezultate zimskog prebrojavanja vodenih ptica kao što su Anas platyrhynchos, Ardea cinerea, Phalacrocorax carbo na rijeci Bosni (Kotrošan & Dervović, 2010). Na osnovu prisustva različitih staništa na istraživanom terenu, moguće je pretpostaviti da ga naseljavaju razne vrste ptica ili ga posjećuju prilikom ishrane i migracije, pogotovo ptice močvarice na području vlažnih staništa. Cilj istraživanja je utvrditi sastav vrsta ptica koje naseljavaju područje Modričkog polja, utvrditi kakve uslove staništa pruža istraživano područje i, po mogućnosti, prikupiti što više podataka o prostornom rasporedu ptičijih populacija, te utvrditi njihove gnijezdeće statuse. Opšte odlike istraživanog područja Modričko polje nalazi se u sjevernom dijelu Bosne i Hercegovine (Republika Srpska), odnosno obuhvata istočni dio opštine Modriča i teritorije grada Modriča. Područje većinom obuhvata poljoprivredne površine nekadašnjeg poljoprivrednog dobra " Petar Mrkonjić " , na kojem je poslije rata izgrađeno i prigradsko naselje, tako da jedan dio istraživanog područja predstavlja naseljeno mjesto MZ Modriča 3. Prostor istraživanja zauzima površinu od oko 8 km 2 , na zapadu je ograničen centrom grada, na jugu regionalnim putem Modriča-Gradačac, na sjeveru putem Modriča-Šamac, a na istoku granicu istraživanog područja predstavlja selo Kladari.

The data was collected during the field research in May 2013 and combined with some earlier findings within the researched area, and personal communication data on the interesting bird fauna of Bijela Gora. All the data obtained will be used for planning future research, in order to nominate this region for the protected area status in both national and international level.
