The Galapagos Archipelago is recognized as a natural laboratory for studying evolutionary processes. San Cristóbal was one of the first islands colonized by tortoises, which radiated from there across the archipelago to inhabit 10 islands. Here, we sequenced the mitochondrial control region from six historical giant tortoises from San Cristóbal (five long deceased individuals found in a cave and one found alive during an expedition in 1906) and discovered that the five from the cave...

Data set for behavioural OA experiments with Caribbean Damselfish (Stegastes partitus)

The neurobehavioural responses of fish exposed to ocean acidification (OA) are variable, possibly due to species-specific differences or involvement of multiple neuronal receptors. Here, we investigated behavioural responses of bicolor damselfish (Stegastes partitus) to OA and the involvement of dopamine receptors. Damselfish were exposed to control (pH 8.06; CO2 ~400 μatm) or OA (pH 7.73; CO2 ~1,000 μatm) seawater for five days, subjected to the open field, novel object approach, light/dark, and mirror-aggression tests, and...

Data: Sex-specific effects of capital resources on reproductive timing and success in red squirrels

Jessica Haines, David Delaney, Andrea Wishart, Andrew McAdam, David Coltman, Jeffrey Lane, Ben Dantzer & Stan Boutin
Reproduction is an energetically expensive activity for both sexes. However, if males and females differ in their annual timing of reproduction, such that peak investment for one sex occurs during a more resource-limited period, there is an opportunity for sex-specific selection to act on the acquisition of energetic resources. Both male and female North American red squirrels (Tamiasciurus hudsonicus) cache conifer cones, although males typically have larger caches than females. Peak energetic investment in reproduction...
