When abundant, seeds of the high-elevation whitebark pine (WBP; Pinus albicaulis) are an important fall food for grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem. Rates of bear mortality and bear/human conflicts have been inversely associated with WBP productivity. Recently, mountain pine beetles (Dendroctonus ponderosae) have killed many cone-producing WBP trees. We used fall ...

Many species and ecosystems are threatened worldwide. Improved problem solving and leadership are needed to address this growing problem. Interdisciplinary problem solving is an innovation that permits leaders to address complex problems more rationally, practically, and morally than use of traditional disciplinary methods. This proven interdisciplinary approach can guide problem solvers in the...

animals are typically portrayed as mindless killing creatures: everybody knows of the “lifeless eyes” of a great white shark or the “killer instinct” of a wolf. However, closer investigation of these animals often reveals complex social, emotional, and psychological features that are often ignored by us fearful, fleshy humans. In this book, G.A. Bradshaw takes readers on a deep dive into the mi...

Under the North American Model of wildlife Conservation, managers are encouraged to update management approaches when new information arises whose implementation could improve viability populations and well-being animals. Here we detail an observation several grizzly bears with amputated toes in southeast British Columbia between 2016-2020 assemble evidence inform strategies remedy issue. Durin...

Biodiversity is severely declining in intensively managed agriculture worldwide. In response, land-management strategies for biodiversity conservation on farmland are in debate, namely ecological intensification and land sparing vs. land sharing. In parallel, there is a recent food vs. energy debate stimulated by an increasing competition for land resources. Despite clear overlaps between these...

Roads can fragment and isolate wildlife populations, which will eventually decrease genetic diversity within populations. Wildlife crossing structures may counteract these impacts, but most crossings are relatively new, and there is little evidence that they facilitate gene flow. We conducted a three-year research project in Banff National Park, Alberta, to evaluate the effectiveness of wildlif...

The Targhee and Bridger-Teton national forests in Idaho and Wyoming provide habitat for grizzly bears (Ursus arctos) from the Yellowstone National Park population (Anonymous 1979). Portions of the forests contain reforestation units scheduled for pocket gopher (Thomomys talpoides) control with strychnine alkaloid-treated grain, a practice used commonly to reduce damage to conifer seedlings by p...

We explored multiple linkages among grey wolves (Canis lupus), elk (Cervus elaphus), berry-producing shrubs and grizzly bears (Ursus arctos) in Yellowstone National Park. We hypothesized competition between elk and grizzly bears whereby, in the absence of wolves, increases in elk numbers would increase browsing on berry-producing shrubs and decrease fruit availability to grizzly bears. After wo...

The red-backed shrike (Lanius collurio L.) is a bird living in human-altered agricultural areas that are managed by extensive farming techniques. This passerine species has declined significantly in Western Europe over the last 30–40 years. The development of efficient species-specific conservation strategies relies on fine-grained information about the ecological resources and environmental co...

The total number of brown bears (Ursus arctos) in Europe is presently about 50,000 (about 14,000 outside Russia), within an area of more than 2.5 million km (800,000 km outside Russia). About 37,500 bears are found in the northeastern European population; 8,100 in the Carpathian Mountains; 2,800 in the Alps–Dinaric–Pindos; 1,000 in Scandinavia; 520 in the Rila–Rhodope Mountains; 200 in the Star...
