..., is impairing phytoplankton production of omega-3 fatty acids (FAs). Here, we assessed the ecological role of omega-3 FAs on chick development and subsequently on breeder foraging behaviour in two closely related shearwater species foraging in contrasting marine environments. We supplemented chicks with omega-3...

... the importance of nutrient balance (P:C) and concentration (P+C) on female foraging behaviour. We measured the oviposition preferences of females in multiple-choice (cafeteria) assays and manipulated the nutritional state of females to test the relative importance of oviposition and feeding in food choices. Next...

As foraging behaviour is a key factor for niche partitioning of co-existing species, we compared nectar extraction behaviour and efficiency at different flower depths among sympatric bat species with different degrees...

Because wing wear has elsewhere been shown to increase mortality, this study provides an important mechanism linking foraging behaviour with lifespan. * Author for correspondence...
