Knowledge of population structure and genetic diversity the spatio-temporal demographic processes affecting populations is crucial for effective wildlife preservation, yet these factors are still poorly understood organisms with large continuous ranges. Available data reveal that widespread mammals have most part only been carefully studied at local scale, which insufficient understanding larger scales. Here, we provide on structure, gene flow in a brown bear inhabiting territory...
Abstract Aim Using sequences of complete mitochondrial genomes, our aims were: (1) to investigate the matrilineal phylogeographical structure, migration patterns and lineage coalescence times in a large, continuous population brown bears ( Ursus arctos ); (2) develop novel spatial genetic method identify corridors barriers. Location North‐western Eurasia: from eastern European Russia Baltic Sea. Methods We sequenced genomes 95 bears. The resolution was compared that derived subsets genome,...
Abstract Aim Climatic changes during the Late Pleistocene had major impacts on populations of plant and animal species. Brown bears other large mammals are likely to have experienced analogous ecological pressures phylogeographical processes. Here, we address several unresolved issues regarding demography brown bears: (1) putative locations refugia; (2) direction migrations across Eurasia into North America; (3) parallels with demographic histories wild modern humans. Location America....
Spatial genetics is a relatively new field in wildlife and conservation biology that becoming an essential tool for unravelling the complexities of animal population processes, designing effective strategies management. Conceptual methodological developments this are therefore critical. Here we present two novel approaches further analytical possibilities STRUCTURE DResD. Using these analyse structure migrations grey wolf (Canis lupus) north-eastern Europe. We genotyped 16 microsatellite...
Abstract The concept of One Health emphasizes the interdependence human, animal and environmental health is growing significance, in part owing to problems related emerging infectious diseases wildlife origin. Wild mammalian predators are a potential risk factor for transmission zoonotic pathogens domesticated animals humans. This especially relevant rural areas, where can occur particularly efficiently when free-ranging dogs present. main aim this study was determine helminth infections...
ABSTRACT Biotic interactions are expected to influence species’ responses climate change, but they usually not included when predicting future range shifts. We assessed the importance of biotic understand consequences and land use change for biodiversity using as a model system brown bear ( Ursus arctos ) in Europe. By including spatial variation energy contribution habitat models each food species, we showed that factors considerably improves our understanding distribution bears. Predicted...
Abstract Mesocarnivores are becoming increasingly influential in ecosystems due to the ongoing loss of large carnivores. However, interactions within mesocarnivore communities remain poorly understood. We studied how competitive coexistence influences cohabitation badgers ( Meles meles ) with other European mesocarnivores, and badger habitat selection at sett site environ scales (within a 700 m radius buffer). used data on location use 234 setts 39 000 km 2 area mainland Estonia (Northern...
Regardless of the highly efficient anthelmintics available and control measures taken by dog owners veterinarians, gastrointestinal parasites, especially zoonotic helminths, are still abundant in dogs pose a health risk to humans. Free-ranging rural areas can be an important source helminth infection. The aims present work were collect scats dogs, determine environmental contamination caused infections among Western Estonia, analyse how diet affects infection rate compare findings previous...
Abstract The brown bear (Ursus arctos) is an iconic carnivoran species of the Northern Hemisphere. Its population history has been studied extensively using mitochondrial markers, which demonstrated signatures multiple waves migration, arguably connected with glaciation periods. Among Eurasian bears, Siberian populations remain understudied. We have sequenced complete genomes four ancient (~4.5–40 kya) bears from South Siberia and 19 modern Russian Far East. Reconstruction phylogenetic...
