Levels of UVB radiation (UVB) and mean temperatures have increased substantially over recent decades in many regions of the world. Both stressors independently can compromise immune function, disease resistance and fitness in fish. The impact of UVB can also be exacerbated by interactions with environmental temperatures. In this paper, we test the hypothesis that UVB and temperature act synergi...
Collective motion, where large numbers of individuals move synchronously together, is achieved when individuals adopt interaction rules that determine how they respond to their neighbors' movements and positions. These rules determine how group-living animals move, make decisions, and transmit information between individuals. Nonetheless, few studies have explicitly determined these interaction...
Human population growth and its associated effects on the environment contribute to rapid decrease of biodiversity worldwide. Artificial light at night (ALAN) is an anthropogenic pollutant that increasing with spread urbanization may declines. ALAN alters migration patterns birds, communication in frogs, impacts reproduction, behavior, physiology multiple other taxa. However, most studies are b...
Aggressive behaviour is linked to fitness, but it is metabolically costly. Changes in metabolic demand during the reproductive cycle could constrain activity and thereby modulate behavioural phenotypes. We predicted that increased metabolic demands in late pregnancy would lead to reduced aggression and a lower metabolic cost of behaviour in the mosquitofish Gambusia holbrooki. Contrary to our p...
