Dispersal costs can be classified into energetic, time, risk and opportunity costs and may be
levied directly or deferred during departure, transfer and settlement. They may equally be …

Sex is shrouded in mystery. Not only does it preferentially occur in the dark for both fungi
and many animals, but evolutionary biologists continue to debate its benefits given costs in …

Most organisms reproduce through outcrossing, even though it comes with substantial costs.
The Red Queen hypothesis proposes that selection from coevolving pathogens facilitates …

It is a commonly held view that genetically homogenous host populations are more
vulnerable to infection than genetically diverse populations. The underlying idea, known as …

Host-parasite species pairs are known to coevolve, but how multiple parasites coevolve with
their host is unclear. By using experimental coevolution of a host bacterium and its viral …

The evolution of sex is one of the most important and controversial problems in evolutionary
biology. Although sex is almost universal in higher animals and plants, its inherent costs …

Both theory and experiments have demonstrated that sex can facilitate adaptation,
potentially yielding a group-level advantage to sex. However, it is unclear whether this …

The coevolution between hosts and parasites is predicted to have complex evolutionary
consequences for both antagonists, often within short time periods. To date, conclusive …

I present a historical review of coevolutionary models for the evolutionary persistence of
sexual reproduction. The focus is on the fate of obligately sexual populations facing …

Understanding how ecological and evolutionary processes interdependently structure
biosphere dynamics is a major challenge in the era of worldwide ecosystem degradation …
