Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, and tissue CORT within 8 and 24 h of stress exposure. Both AOP and NOP tadpoles reduced their activity in acidic pH, but the response to the predator cue differed between the populations: AOP tadpoles increased whereas NOP tadpoles decreased their activity. The AOP and NOP tadpoles differed also in their CORT responses, with AOP being more responsive (CORT levels of NOP tadpoles did not differ statistically across treatments). After 8 h exposure, AOP tadpoles had elevated CORT levels in the acid-predator cue treatment and after 24 h exposure they had elevated CORT levels in all three stress treatments (relative to the benign neutral–no-cue treatment). These results suggest that adaptation to environmental acidification in R. arvalis is mediated, in part, via behavioural and hormonal plasticity.

Context dependent variation in corticosterone and phenotypic divergence of Rana arvalis populations along an acidification gradient
Mausbach, Jelena; Laurila, Anssi; Räsänen, Katja (Biomed Central, 2022)Background Physiological processes, as immediate responses to the environment, are important mechanisms of phenotypic plasticity and can influence evolution at ecological time scales. In stressful environments, physiological ... -
Poison frog social behaviour under global change : potential impacts and future challenges
Schlippe Justicia, Lia; Fouilloux, Chloe A.; Rojas, Bibiana (Springer Science and Business Media LLC, 2022)The current and cascading effects of global change challenges the interactions both between animal individuals (i.e. social and sexual behaviour) and the environment they inhabit.

An evolutionary perspective on stress responses, damage and repair
Taborsky, Barbara; Kuijper, Bram; Fawcett, Tim W.; English, Sinead; Leimar, Olof; McNamara, John M.; Ruuskanen, Suvi (Elsevier, 2022)Variation in stress responses has been investigated in relation to environmental factors, species ecology, life history and fitness. Moreover, mechanistic studies have unravelled molecular mechanisms of how acute and chronic ... -
Secondhand horror : effects of direct and indirect predator cues on behavior and reproduction of the bank vole
Sievert, Thorbjörn; Haapakoski, Marko; Palme, Rupert; Voipio, Helinä; Ylönen, Hannu (Ecological Society of America, 2019)Risk recognition by prey is of paramount importance within the evolutionary arms race between predator and prey. Prey species are able to detect direct predator cues like odors and adjust their behavior appropriately. The ... -
Tadpole Responses to Environments With Limited Visibility : What We (Don’t) Know and Perspectives for a Sharper Future
Fouilloux, Chloe A.; Yovanovich, Carola A. M.; Rojas, Bibiana (Frontiers Media SA, 2022)Amphibian larvae typically inhabit relatively shallow freshwater environments, and within these boundaries there is considerable diversity in the structure of the habitats exploited by different species. This diversity in ...
