We compiled, summarized and reviewed 338 cases of people killed or injured by brown bears from 1932 to 2017 in Russia, home of about half of the world's brown bears. During the Soviet period, 1932-1990, hunters and outdoor workers were injured/killed by bears more frequently than people engaged in other activities, 28% and 19% among all incidents, respectively. However, after 1991, people who gathered wild resources, hiked or were within human settlements were most affected (22, 16 and 15%, respectively). Single bears were involved in most of the incidents before and after 1991 (76% and 74% of the cases, respectively). In 1991-2017, the post-Soviet period, when data availability was better, bear-caused injuries and fatalities (264 records) occurred more often on the Russian Pacific Coast (111 incidents) and in Siberia (109 incidents) than in European Russia (44 incidents), where human encroachment in bear habitat is higher. During the same period, the percentages of fatalities were not significantly different among the areas; 39% in European Russia, 49% in Siberia and 50% on the Pacific Coast. Casualties occurred mainly during daytime and especially in summer and autumn. In 182 incidents with known probable causes, bears most frequently attacked when provoked or disturbed (38%) and surprised (21%), but 18% of the incidents seemed to reflect bear predatory behavior. Hence, we encourage researchers and wildlife managers to develop educational programs on large carnivore biology and behavior and to better manage human activities in bear country in order to minimize human-bear conflicts in Russia and elsewhere.

The data about the community composition, number and biomass of amphipods in three gulfs of the North-Western Black Sea are presented. The amphipod communities of the gulfs of Yahorlyk, Karkinit, and Tendra were studied and the species composition was compared with the previously published data. For each particular gulf, the list of amphipod species was composed. The quantitative parameters of the amphipod communities in the studied localities in different years were described.

Threat to human safety is the most dramatic conflict between humans and large carnivores. Although carnivore attacks are generally rare, bears are relatively often involved. Here, we reveal an association between human encroachment into the landscape, that is, increasing road density, and brown bear-caused human casualties (injuries and fatalities) in Russia. In European Russia, the frequency of casualties correlated positively with bear population size and negatively with the presence of Siberian pine, a crucial bear food in the predenning period and a commonly gathered human resource. In Siberia, however, the number of casualties was not related to the number of bears, but it was positively associated with both road density and the presence of Siberian pine. Increasing casualties there were seemingly linked to increasing access to areas where both humans and bears concentrated simultaneously to harvest the same resource, edible pine seeds. The latter are more often collected commercially in Siberia than in European Russia. Our study shows the link between habitat degradation and human-wildlife conflict. Indeed, interacting effects of habitat change and coexistence with large carnivores deserve further attention, as we illustrate here for Russian forests; a wide boreal ecosystem where human encroachment can have severe repercussions for wildlife and ecosystem functioning at multiple spatial levels.
