Repeatability and heritability of social reaction norms in a wild agamid lizard

Kasha Strickland, David Mitchell, Coralie Delmé & Celine Frère
In the evolutionary transition from solitary to group living, it should be adaptive for animals to respond to the environment and choose when to socialise to reduce conflict and maximise access to resources. Due to the associated proximate mechanisms (e.g. neural network, endocrine system), it is likely that this behaviour varies between individuals according to genetic and non-genetic factors. We used long-term behavioural and genetic data from a population of eastern water dragons (Intellagama lesueurii)...

Genetic variation for upper thermal tolerance diminishes within and between populations with increasing acclimation temperature in Atlantic salmon

Paul Vincent Debes, Monica Favnebøe Solberg, Ivar Helge Matre, Lise Dyrhovden & Kevin Alan Glover
Populations may counteract lasting temperature changes or recurrent extremes through plasticity or adaptation. However, it remains underexplored how outbreeding, either naturally, unintentionally, or facilitated, may modify a local response potential and whether genotype-by-environment interactions or between-trait correlations can restrict this potential. We quantified population differences and outbreeding effects, within-population genetic variation, and plasticity of these, for thermal performance proxy traits using 32 pedigreed wild, domesticated, and wild-domesticated Atlantic salmon families reared under common-garden conditions. Following...

Data from: The alternative oxidase (AOX) increases sulphide tolerance in the highly invasive marine invertebrate Ciona intestinalis

Katharina Bremer, Hitoyoshi Yasuo, Paul Vincent Debes & Howard Trevor Jacobs
Ecological communities and biodiversity are shaped by both abiotic and biotic factors. This is well illustrated by extreme environments and invasive species. With global change, hydrogen sulphide is an increasing threat for many multicellular organisms. As the formation, size, and abundance of hydrogen sulphide-rich marine environments increase, many species are challenged with the inhibiting effect of sulphide on the aerobic energy production via cytochrome c oxidase, ultimately causing the death of the organism. Interestingly, many...

Variation in parasite resistance of Arctic charr, Salvelinus alpinus, between and within sympatric morphs

Anssi Karvonen, Samantha Beck, Skúli Skúlason, Bjarni Kristjánsson & Camille Leblanc
Genetic variation in resistance against parasite infections is a predominant feature in host-parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally poorly known. We explored if differences in natural infection pressure between resource-based morphs of Arctic charr (Salvelinus alpinus) has resulted in differentiation in resistance profiles. We experimentally exposed offspring of two morphs from Lake Þingvallavatn (Iceland), the pelagic planktivorous charr (‘murta’) and the large benthivorous charr (‘kuðungableikja’), to...
