Sexual reproduction is almost ubiquitous among multicellular organisms even though it
entails severe fitness costs. To resolve this apparent paradox, an extensive body of research …

Parasites represent a great proportion of the world's living organisms and are of
overwhelming significance because of their impact on hosts (evolutionarily, medically …

Cryptococcus neoformans is a human-pathogenic fungus that has evolved into three distinct
varieties that infect most prominently the central nervous system. A sexual cycle involving …

Explaining the selective forces that underlie different reproductive modes forms a major part
of evolution research. Many organisms are facultative sexuals, with the ability to reproduce …

Sexual selection is a major force driving the evolution of elaborate male sexual traits.
Handicap models of sexual selection predict that male sexual traits should covary positively …

Understanding the maintenance of sexual reproduction constitutes a difficult problem for
evolutionary biologists because of the immediate costs that sex seems to incur. Typically …

Neutral models characterize evolutionary or ecological patterns expected in the absence of
specific causal processes, such as natural selection or ecological interactions. In this study …

Facultative parthenogenesis has great adaptive significance, especially with regard to low
pairing efficiency. In the termite Reticulitermes speratus, females that fail to mate with males …

In hexapods, unlike the majority of animals, development without fertilization is a common
phenomenon. They evolved a striking diversity of unisexual reproductive types that include a …

Female mate choice has been demonstrated in a wide variety of species and is now
accepted as an important factor in sexual selection. One of the remaining questions …
