Major supratidal and intertidal dietary items available to black bears varied annually.
Not surprisingly, body size in bears varies accordingly [ 48, 49], having ramifications to both survival [ 43, 50, 51] and reproduction [ 48, 52, 53].
The diet of brown bears varies considerably across their distribution, but in most areas, it is largely dominated by carbohydrates and supplemented with meat when available, although salmon make a major contribution in coastal areas (Rode and Robbins 2000; Mowat and Heard 2006).
To do this more effectively, different sub-samples could be given different information (concerning, for instance, the costs that they would have to bear), varied in such a way that the pollsters could deduce the voters' preferences on distribution and discount rates.
They argued it was unjustified because estimates of the size of the state's bear population vary widely, from about 1,300 to nearly 3,000.
The number of times needed to clean the bore will vary greatly depending on many variables.
A recent working paper by three economists at the European Central Bank points out that the debt consumers can bear varies with interest rates, house prices, the rate of home-ownership, the share of the population aged 35-54, the deposit first-time house-buyers are required to make and the foreclosure rate.
Canopy gap creation by black bears would also vary depending on year-to-year fluctuations in seed production and black bear populations.
In contrast, microbial communities present in polar bear feces varied to a larger extent (Schwab and Ganzle 2011).
