Inferring female extra-pair mating behaviour from observed patterns of extra-pair paternity with a process-based model
(The University of Bergen, 2014-10-01)
There has been great focus on extra-pair paternity (EPP) in birds over the last decades. The knowledge gained has made researchers rethink certain notions about mating behaviour in birds. Initially it was believed that ...
Gelatinous zooplankton in western Norwegian fjords. Ecology, systematics and comparisons with adjacent waters
(The University of Bergen, 2007-05-16)
Gelatinous zooplankters, also known as jellies, are ubiquitous in the marine pelagic. Medusae, siphonophores and ctenophores are voracious predators that can, when abundant, have significant structuring effects on the ...
Feeding behavior and bioenergetic balance of the great scallop (Pecten maximus) and the blue mussel (Mytilus edulis) in a low seston environment and relevance to suspended shellfish aquaculture.
(The University of Bergen, 2009-11-20)
