Monitoring rodents' life history by body temperature and activity

Wildlife Biology, EarlyView.
European hamster populations are rapidly declining all over their distribution area. One of the suggested reasons is a strong and ongoing decrease in the reproductive output of about 77% since the nineteen twenties. The cause of this decline is, however, unknown.

Fecundity of the Lagune Cow in Benin. Age at first calving and Calving Intervals

, 2005
Data collected from 1987 to 2003 at the Samiondji farm in Benin were used to study the age at first calving (n = 200) and calving intervals (n = 805) in the Lagune cow.

Interactions between prairie dogs and arthropods in grassland ecosystems: a review and research gaps

Wildlife Biology, EarlyView.
Prairie dogs (Cynomys spp.) are an important component of grassland ecosystems of North America where they can alter vegetation composition/structure and physical attributes of grassland habitats through their feeding and burrowing behavior. Impacts of prairie dog presence on many wildlife and plant taxa have been widely studied but research on prairie

Forest and fire drive moose (deníe) detections near their northern range limit

Wildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

Feeding Practices and Welfare of Zoo‐Housed Giraffes (Giraffa camelopardalis) on a Global Scale

Zoo Biology, EarlyView.
We collected feeding and stereotypy information on 702 giraffes from 146 zoos from all over the world. Less appropriate diets were linked to more oral stereotypies. ABSTRACT Since giraffe feeding practices have only been reported for European and US facilities, this study aimed to achieve a comprehensive overview of the current giraffe feeding ...

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.

PROFITABILITY OF ESTABLISHING BASIN WILDRYE FOR WINTER GRAZING [PDF]

This study examined the economic viability of establishing basin wildrye for winter grazing. Mixed integer-programming models were developed that minimized cow feed costs. Estimated basin wildrye establishment costs were $154 per acre.

Rising temperature non‐additively alters how different dimensions of biodiversity affect ecosystem‐scale processes

Journal of Animal Ecology, EarlyView.
The authors distil how dimensions of biodiversity drive ecosystem processes with increasing temperature. Specifically, species physiology more greatly affected ecosystem primary production than did foraging behaviour, and physiology mediated non‐additive interactions with temperature.
