AbstractThe life cycle and distribution of the bearded seal (Erignathus barbatus) are closely related to fluctuations of the ice edge during the year. The Sea of Okhotsk is a seasonally freezing water area, which is completely ice free in summer. This determines the annual cycle of the bearded seal and makes it unique compared to populations from o...

AbstractThe diversity of foraging behaviour in waterfowl species is often estimated to mostly be the result of adaptations to different foraging habitats and diets. Understanding of adaptive radiation within a rapidly multiplying lineage can be used to detect behavioural patterns and can also be useful in identifying the underlying factors in the e...

AbstractBioremediation using microorganisms to remediate petroleum hydrocarbon contaminated soils is considered as a sustainable approach to cleaning polluted sites. One element of the sustainability is providing nutrients (biostimulation) for degrading microbial populations by using organic wastes such as animal manures rather than conventionally ...

Abstract—The long-term dynamics of β-diversity of small mammal (SM) communities in the vicinity of a large copper smelter has been analyzed during the periods of high (1990–1997), reduced (1998–2009), and almost terminated emissions (2010–2020). The results show that the β-diversity of communities increases as the smelter is approached, with the le...

AbstractMost ecotoxicological studies on the toxicity of metals in soil are conducted using artificially contaminated soils, i.e., originally uncontaminated soils to which increasing amounts of metals are added in the form of soluble salts in a laboratory setting. This approach has been rightly criticized because of the difficulty of extrapolating ...

Abstract—This paper studies the differences in the trophic resource use in the breeding time between the snow goose Anser caerulescens that is the most abundant in the Arctic and the most widespread brant goose Branta bernicla under the conditions of the main part of the snow goose nesting range (Colville River Delta, Alaska). It was found that the...

Abstract—Global climate change has led to shifts in the frequency and severity of extreme eather and climatic events, including the occurrence of extremely low temperatures during the growing period, which results in frost damage to living xylem cells. In this study, the frequency of frost damages in larch has been assessed along a 4000-km transect...

AbstractBased on the long-term laboratory rearing of gypsy moth larvae on an artificial diet with different modifications, which were taken from egg masses in the same forest area in different phases of the population dynamics, we have studied the effect of biotic and abiotic factors on the duration of the development and survival rate of larvae at...

AbstractWe surveyed the vegetation in Deogyusan National Park (conservation areas) and surrounding areas outside the park (Mt. Juksang, Mt. Johang and Mt. Bonghwa). We calculated plant community indices and diversity indices; these identified properties of the surrounding areas that are relevant to conservation efforts in the park. We compared the ...

AbstractThe growth rate of the first lower molar and its wear features have been studied in narrow-skulled vole individuals (n = 39) that received hard and soft feeds under laboratory conditions. Using tetracycline markers, we have found that the tooth height increases by 0.33–0.56 mm throughout the day. Voles that received soft feed, in general, h...
