Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...

Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblages
DownloadSpring 2010
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...

The degree to which predator and prey distributions overlap in space influences the probability of encounters between predator and prey, kills of prey, and consequently, how each species’ abundance varies in time and in space. Predator and prey attempt to increase or decrease overlap respectively...
