Effects of dominance and female presence on secondary sexual characteristics in male tufted capuchin monkeys (Sapajus apella)

Annika Paukner, Emily Slonecker & Lauren Wooddell
Alpha status may lead to physiological changes that enhance secondary sexual characteristics, which may serve as competitive signals to conspecific males, sexual signals to females, or possibly a combination of both. Here we report measurements of secondary sexual characteristics in captive dominant and subordinate male tufted capuchin monkeys (Sapajus apella) with varying access to females. An adult male (who had previously been subordinate while housed with other males) was paired with an adult female, and...

The social function of the feeling and expression of guilt

Eglantine Julle-Danière, Jamie Whitehouse, Aldert Vrij, Erik Gustafsson & Bridget M Waller
Humans are uniquely cooperative and form crucial short- and long-term social bonds between individuals that ultimately shape human societies. The need for such intense cooperation may have provided a particularly powerful selection pressure on the emotional and communicative behaviours regulating cooperative processes, such as guilt. Guilt is a social, other-oriented moral emotion that promotes relationship repair and pro-sociality. For example, people can be more lenient towards wrongdoers who display guilt than towards those who do...

Data from: As time goes by: 20 years of changes in the aquatic macroinvertebrate metacommunity of Mediterranean river networks

Aim: to analyse temporal metacommunity dynamics in river networks in relation to hydrological conditions and dispersal. Location: 15 river reaches from the Llobregat, Besòs and Foix catchments in the North-Eastern Iberian Peninsula. Taxon: aquatic macroinvertebrates belonging to 99 different families. Methods: we sampled aquatic macroinvertebrate communities during spring in 20 consecutive years. We built two environmental distances (one related with water chemistry and another one with river flow regime) and two spatial distances (network distance...

Local and regional drivers influence how aquatic community diversity, resistance and resilience vary in response to drying

Romain Sarremejane
Disturbance events govern how the biodiversity of ecological communities varies in both space and time. In freshwater ecosystems, there is evidence that local and regional-scale drivers interact to influence ecological responses to drying disturbances. However, most research provides temporal snapshots at the local scale, whereas few studies encompass a gradient of drying severity spanning multiple years. Using a dataset of rare spatiotemporal extent and detail, we demonstrate how independent and interacting local and regional-scale factors...
