By spending more time around infants which physically resemble their own, mandrill mothers may increase how frequently their offspring interact with their paternal half siblings.

The EVolutionary biorEactor (EVE) can be built for less than $200, and can be used to evaluate microbial population dynamics in the lab and to teach evolution in high schools.
A shift in fitness optimum of a polygenic trait rapidly introduces small frequency differences between alleles with effects aligned with and opposing the shift, which gradually translate into small differences in fixation probability.

Analysis of microbial communities in floral nectar shows that it is possible to identify an overarching factor that governs the eco-evolutionary dynamics of priority effects across multiple levels of biological organization.

Neotropical outstanding biodiversity emerged from sustained rates of species accumulation over time, although, for some periods, tetrapods were less successful than plants in keeping pace with a changing environment.

Extensive field studies in poison frogs reveal that sex and species differences in parental behavior drive differences in space use patterns but not navigational performance and highlight the interplay between androgen levels and poison frog spatial behavior.

Mandrill mothers know best because they use their offspring’s facial resemblance with other infants to guide their social opportunities towards similar-looking ones as an adaptive maternal behavior.
Jaw joint regulatory sequence 1 (JRS1) is deeply conserved in most jawed vertebrates and displays a specific enhancer activity in the developing primary jaw joint that contributes to early nkx3.2 gene expression and jaw joint morphology.
