The protein composition of sperm and seminal fluid are key to male fitness. However, we currently lack an understanding of the factors that shape seminal proteome composition. The common bedbug (Cimex...

Do you want to conduct frontier research in an outstanding environment within evolutionary biology at Sweden’s largest faculty of science and technology? The Department of Ecology and Genetics at Up

Award-winning novelist celebrates late partner’s love of birds with gift to establish the Graeme Gibson chair in avian biology

Abstract. Evolutionary trajectories are determined by selection and the underlying genetic architecture of additive genetic variances and covariances for t

Rhynchospora tenuis undergoes obligate, genome-wide achiasmy in both male and female meiosis.

Abstract. Although strong evidence links social connectedness to improved fitness, there is pronounced among-individual variation in social behaviour. This

Understanding how between-species interactions influence adaptation and population persistence in the face of environmental change is one of the gr...

This lecture series is designed to promote the principles of gold standard science by providing a formal venue for thoughtful discussion of complex scientific topics. Each session will highlight areas...

Abstract. We investigate the evolutionary dynamics of sexually selected traits using both a mathematical model and comparative analyses, focusing on the re

Sex can be complicated—just ask bed bugs. The bane of many conference goers, these blood-feeding parasitic insects mate via traumatic insemination, a repro

Abstract. Intergenerational and transgenerational fitness effects can shape evolutionary processes. Theoretically, however, intergenerational and transgene

Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, the University of Siena in Italy and the University of Szeged in Hungary reveals a more surprising reality, where success can depend less on competition and more on cooperation.

Birds have a lot to do in their short lives: defend territories, build nests, raise chicks and feed themselves. But the toll of these activities may be greater for female birds than for male birds.

AI will reorganize science. Will research remain a human enterprise?

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

We recorded songs of male pied flycatchers when they were unmated (twice) and when the same males were mated and displaying on a secondary territory. The syllable switching was much higher after mati...

In mammals, males are usually stronger and more competitive than females. Males also show greater inequality in reproductive success—the number of offspring they produce—than females.

Abstract. Sexual conflict arises when the reproductive interests of males and females diverge, leading to decreased female fitness due to male‐induced harm

Abstract. Phenotypic trade-offs, predicted to occur due to resource limitation, are not commonly detected. For this, the Y-model provides a powerful heuris

Our recent article about the origin, genomics and evolution of female-limited polymorphisms in animals document a widespread phenomenon, with implications for evolutionary biology and society.
