By combining mark-recapture and genetic parentage data from wild #lizards, we show that the offspring of older parents do not have lower survival or reproductive success than the offspring of younger parents:

Abstract. As organisms age, the fitness of the offspring they produce can decline, which is often attributed to parental senescence. However, few studies h

Our new paper offers an explanation for the universal law that "under carefully controlled conditions.... an animal behaves as it damn well pleases." We explore how stochastic mechanisms may play an underappreciated role in generating individuality. (1/7 🧵)

Female mosquitoes control mating through subtle genital movements, determining if and when copulation occurs—a key factor in their reproductive success and the spread of mosquito-borne diseases. doi.org/g98bcr
What we got wrong about mosquito mating—researchers explain why females are in charge
The female mosquito only mates once in her lifetime, and yet she can develop many hundreds of eggs from this single event.

Social relationships are powerful predictors of fitness across social animals. But *why*?

In our new @cp-trendsecolevo.bsky.social paper, we outline testable predictions for why relationship quality and quantity adaptively vary across socio-ecological contexts.

Scientists have uncovered how social life shapes aggression in fruit flies: while loners rely on quick jabs, group-raised males prefer intense, full-on tussles, a shift that helps them win territory and mates.
