Trophic cascades from wolves to grizzly bears or changing abundance of bears and alternate foods?

چکیده
This is a Forum article commenting on: Ripple, W. J., Beschta, R. L., Fortin, J. K., & Robbins, C. T. (2014) Trophic cascades from wolves to grizzly bears in Yellowstone. Journal of Animal Ecology, 83, 223-233. Comparisons Ripple et al. (2014) used to demonstrate increased fruit availability and consumption by grizzly bears post-wolf reintroduction are flawed and tenuous at best. Importantly, a more parsimonious (than trophic cascades) hypothesis, not sufficiently considered by Ripple et al., exists and is better supported by available data I review.

Wolves trigger a trophic cascade to berries as alternative food for grizzly bears.
This is a Forum article in response to: Barber-Meyer, S. (2015) Trophic cascades from wolves to grizzly bears or changing abundance of bears and alternate foods? Journal of Animal Ecology, 83, doi: 10.1111/1365-2656.12338. We used multiple data sets and study areas as well as several lines of evidence to investigate potential trophic linkages in Yellowstone National Park. Our results suggest th...
متن کاملTrophic cascades from wolves to grizzly bears in Yellowstone.
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...
متن کاملMajor decline in marine and terrestrial animal consumption by brown bears (Ursus arctos)
Human activities have had the strongest impacts on natural ecosystems since the last glacial period, including the alteration of interspecific relationships such as food webs. In this paper, we present a historical record of major alterations of trophic structure by revealing millennium-scale dietary shifts of brown bears (Ursus arctos) on the Hokkaido islands, Japan, using carbon, nitrogen, an...
متن کاملCompetition between apex predators? Brown bears decrease wolf kill rate on two continents
Trophic interactions are a fundamental topic in ecology, but we know little about how competition between apex predators affects predation, the mechanism driving top-down forcing in ecosystems. We used long-term datasets from Scandinavia (Europe) and Yellowstone National Park (North America) to evaluate how grey wolf (Canis lupus) kill rate was affected by a sympatric apex predator, the brown b...
متن کاملEffects of Food Supply, Predation, Cannibalism, Parasites, and Other Health Problems on Black Bear Populations
Effects of gunshot and human settlement on black bear numbers and range are well documented, but effects of natural factors are less well known. In this paper, effects of food supply, predation, cannibalism, and health problems on black bear populations are evaluated using information in the literature and data obtained in Minnesota during 1969-1978 from 119 radiocollared black bears and their ...
