Use of isotopic sulfur to determine whitebark pine consumption by Yellowstone bears: A reassessment
Wildlife Society Bulletin, 2014 Use of naturally occurring stable isotopes to estimate assimilated diet of bears is one of the single greatest breakthroughs in nutritional ecology during the past 20 years. Previous research in the Greater Yellowstone Ecosystem (GYE), USA, established a

Prolonged transition time between colostrum and mature milk in a bear, the giant panda, Ailuropoda melanoleuca [PDF]
, 2015 Bears produce the most altricial neonates of any placental mammal. We hypothesized that the transition from colostrum to mature milk in bears reflects a temporal and biochemical adaptation for altricial development and immune protection.

Density and reproductive characteristics of female brown bears in the Cantabrian Mountains, NW Spain [PDF]
, 2018 Here we present annual nearest-neighbour distances (as a proxy of density) between females with cubs-of-the-year (hereafter FCOY) and reproductive characteristics of brown bears Ursus arctos in the Cantabrian Mountains (NW Spain), from 1989 to 2017. FCOY

Density and genetic diversity of grizzly bears at the northern edge of their distribution
Ecosphere, 2023 Species at the periphery of their range are typically limited in density by poor habitat quality. As a result, the central–marginal hypothesis (CMH) predicts a decline in genetic diversity of populations toward the periphery of a species' range.

Problem Perspectives and Grizzly Bears: A Case Study of Alberta’s Grizzly Bear Recovery Policy
Frontiers in Ecology and Evolution, 2020 Since their threatened species listing in 2010, grizzly bear recovery has been a controversial policy issue in Alberta, Canada particularly because this charismatic carnivore represents a diverse set of values, both positive (e.g., an icon of beauty and ...

From human invaders to problem bears: A media content analysis of grizzly bear conservation
Conservation Science and Practice, 2020 Across their North American range, grizzly bears (Ursus arctos) occupy a special place in human imagination, as icons of nature's rugged and raw power, to representations of safety risks and economic costs of living with carnivores.
