Titin isoform switching is a major cardiac adaptive response in hibernating grizzly bears
, 2008 The hibernation phenomenon captures biological as well as clinical interests to understand how organs adapt. Here we studied how hibernating grizzly bears (Ursus arctos horribilis) tolerate extremely low heart rates without developing cardiac chamber ...

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Trophic cascades from wolves to grizzly bears or changing abundance of bears and alternate foods?
, 2015 In ‘Trophic cascades from wolves to grizzly bears in Yellowstone’, Ripple et al. (2014) hypothesize that a wolf (Canis lupus)-caused trophic cascade has resulted in increased consumption of fruit by grizzly bears (Ursus arctos) in Yellowstone National ...

Predation risk and space use of a declining Dall sheep (Ovis dalli dalli) population.
PLoS ONE, 2019 The abundance of ungulate populations may fluctuate in response to several limiting factors, including climate, diseases, and predation. In the northern Richardson Mountains, Canada, Dall sheep (Ovis dalli dalli) have undergone a major decline in the ...

Ecological effects of mine reclamation on grizzly bears
, 2012 The grizzly bear (Ursus arctos) is a threatened species in Alberta and although we have studied grizzly bear response to forest seral stage change, little is known about the response to coal mine reclamation by bears.

Advanced Materials, EarlyView.Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Conservation of grizzly bears using access management
, 2010 Grizzly bears avoid roads in some areas but select areas near roads in others. This is driven by mechanisms such as traffic patterns and food resources near roads.
