Demographic measures of an individual's "pace of life": fecundity rate, lifespan, generation time, or a composite variable?
(Journal article; Peer reviewed, 2018)Comparative analyses have demonstrated the existence of a ^pace-of-life^ (POL) continuum of life-history strategies, from fastreproducing short-lived species to slow-reproducing long-lived species. This idea has been ... -
Effect of sand texture on nest quality and mating success in a fish with parental care
(Journal article; Peer reviewed, 2019)Nest quality is an important aspect of courtship and mate choice, offering females direct benefits through offspring survival and, if it reflects male genetic quality, also indirect ones. Nest characteristics may thus ... -
The effects of egg incubation temperature and parental cross on the swimming activity of juvenile brown trout Salmo trutta
(Peer reviewed; Journal article, 2023)temperature had carry-over effects on swimming activity of juvenile brown trout, Salmo trutta. Eggs from different crosses involving anadromous and lacustrine-adfluvial parents were incubated under two temperature regimes, ... -
Refrigeration or anti-theft? Food-caching behavior of Wolverines (Gulo gulo) in Scandinavia
(Journal article, 2020)Food-caching animals can gain nutritional advantages by buffering seasonality in food availability, especially during times of scarcity. The wolverine (Gulo gulo) is a facultative predator that occupies environments of low ... -
Sex in murky waters: algal-induced turbidity increases sexual selection in pipefish
