All multicellular organisms host microbial communities in and on their bodies, and these
microbiomes can have major influences on host biology. Most research has focussed on the …

How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

Adaptive radiations are generated through a complex interplay of biotic and abiotic factors.
Although adaptive radiations have been widely studied in the context of animal and plant …

Sperm production and allocation strategies have been a central concern of sperm
competition research for the past 50 years. But during the 'sexual cascade'there may be …

Seminal fluid proteins (SFPs) are a group of reproductive proteins that are among the most
evolutionarily divergent known. As SFPs can impact male and female fitness, these proteins …

This review provides an updated overview of the seminal plasma composition, and the role
of metabolic and protein components on the sperm function of avian species. In addition, the …

In the three decades, since Birkhead and Møller published Sperm competition in birds
(1992, Academic Press) more than 1000 papers have been published on this topic, about …

From the northernmost tip of Scandinavia to the southernmost corner of Patagonia, and
across six continents, house sparrows (Passer domesticus) inhabit most human-modified …

Ejaculate proteins are key mediators of post-mating sexual selection and sexual conflict, as
they can influence both male fertilization success and female reproductive physiology …

Gene expression has a key role in reproductive isolation, and studies of hybrid gene
expression have identified mechanisms causing hybrid sterility. Here, we review the …
