Metacommunity structure in a small boreal stream networkJournal of Animal Ecology - Tập 82 Số 2 - Trang 449-458 - 2013
Emma Göthe, David G. Angeler, Leonard Sandin
SummaryCurrent ecological frameworks emphasize the relative importance of local and regional drivers for structuring species communities. However, most research has been carried out in systems with discrete habitat boundaries and a clear insular structure. Stream networks deviate from the insular structure and can serve as excelle...... hiện toàn bộ
The importance of biotic interactions in abundance–occupancy relationshipsJournal of Animal Ecology - Tập 71 Số 5 - Trang 846-854 - 2002
Alison R. Holt, Philip H. Warren, Kevin J. Gaston
SummaryMetapopulation dynamics have been postulated as a possible mechanism giving rise to positive interspecific relationships between local abundance and regional occupancy. These may operate through the carrying capacity or the rescue effect hypotheses. However, both are based on single species models...... hiện toàn bộ
Individual variation in prey selection by sea otters: patterns, causes and implicationsJournal of Animal Ecology - Tập 72 Số 1 - Trang 144-155 - 2003
James A. Estes, Marianne Riedman, Michelle M. Staedler, M. Tim Tinker, Bruce E. Lyon
SummaryLongitudinal records of prey selection by 10 adult female sea otters on the Monterey Peninsula, California, from 1983 to 1990 demonstrate extreme inter‐individual variation in diet. Variation in prey availability cannot explain these differences as the data were obtained from a common spatial‐temp...... hiện toàn bộ
