Optimal swimming strategies in mate-searching pelagic copepods

T Kiørboe - Oecologia, 2008 - Springer
Male copepods must swim to find females, but swimming increases the risk of meeting
predators and is expensive in terms of energy expenditure. Here I address the trade-offs …

Facultative semelparity in capelin Mallotus villosus (Osmeridae)-an experimental test of a life history phenomenon in a sub-arctic fish

JS Christiansen, K Præbel, SI Siikavuopio… - Journal of Experimental …, 2008 - Elsevier
Two alternative reproductive modes are present in fishes and reflect the age-specific

Intra-and inter-annual shifts in foraging tactics by parental northern gannets Morus bassanus indicate changing prey fields

KJN d Entremont, GK Davoren, CJ Walsh… - Marine Ecology …, 2022 - int-res.com
Seabirds are constrained by central-place foraging during breeding, when the energy
obtained from prey must outweigh the costs of travel, search, capture and transport. The …

Critical threshold size for overwintering sandeels (Ammodytes marinus)

M van Deurs, M Hartvig, JF Steffensen - Marine Biology, 2011 - Springer
Several ecologically and commercially important fish species spend the winter in a state of
