Threats to the World's Bears and Efforts to Conserve Them: Perspectives and Actions of IUCN Bear Specialist Group Members 世界熊类面临的威胁及其保护努力:IUCN熊类专家组成员的观点与行动

Integrative Conservation, EarlyView.
A survey of IUCN Bear Specialist Group (BSG) members revealed that habitat loss, degradation and fragmentation is the greatest threat to each of the 7 species of terrestrial bears. Poaching and human–bear conflicts are also high threats for some of these species.

Trichinella T9 in wild bears in Japan: Prevalence, species/genotype identification, and public health implications

International Journal for Parasitology: Parasites and Wildlife, 2023
In Japan, the recent series of sporadic outbreaks of human trichinellosis caused by Trichinella (Nematoda: Trichocephalida) has occurred owing to the consumption of raw or insufficiently cooked meat from wild bears.

Harnessing personal and social resources in managing internalising and externalising symptoms in children living in low‐resource settings

JCPP Advances, EarlyView.
Abstract Background Children growing up in low‐resource settings are at greater risk for lifelong psychiatric problems. They are both more likely to have risk factors for early psychopathology and to be less likely to seek help and engage support for these problems.

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

Journal of Quaternary Science, EarlyView.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

The Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.
