Molecular basis of ocean acidification sensitivity and adaptation in .

Predicting the potential for species adaption to climate change is challenged by the need to identify the physiological mechanisms that underpin species vulnerability. Here, we investigated the sensitivity to ocean acidification in marine mussels during early development, and specifically the trochophore stage. Using RNA and DNA sequencing and RNA hybridization, we identified developmental processes associated with abnormal development and rapid adaptation to low pH.

Landscape structure and population density affect intraspecific aggression in beavers.

Intraspecific competition plays an important role for territory acquisition and occupancy, in turn affecting individual fitness. Thus, understanding the drivers of intraspecific aggression can increase our understanding of population dynamics. Here, we investigated intraspecific aggression in Eurasian () and North American () beavers that are both monogamous, territorial mammals.
