Range shifts can rapidly create new areas of geographic overlap between formerly allopatric
taxa and evidence is accumulating that this can affect species persistence. We review the …

Although the primary function of mating is gamete transfer, male ejaculates contain
numerous other substances that are produced by accessory glands and transferred to …

One of the most enigmatic observations in evolutionary biology is the evolution of
morphological or physiological traits in one sex that physically injure members of the other …

Male reproductive success is dependent on insemination success and reproductive output.
During mating, male mosquitoes transfer not just sperm, but also seminal fluid proteins that …

Traumatic mating (or copulatory wounding) is an extreme form of sexual conflict whereby
male genitalia physically harm females during mating. In such species females are expected …

Despite the key functions of the genitalia in sexual interactions and fertilization, the role of
sexual selection and conflict in shaping genital traits remains poorly understood. Seed …

Despite widespread evidence for the benefits of polyandry, there are costs associated with
each mating for females, and for many species, it is unknown whether the costs of extra …

Insect body temperature is usually determined by ambient temperature. Therefore, most
biochemical and physiological processes underlying behavioural patterns are temperature …

Life-history theory predicts a trade-off between reproductive investment and self-
maintenance. The negative association between fertility and longevity found throughout …

While polyandry is essentially ubiquitous across the animal kingdom, the net fitness
consequences of multiple mating remain the subject of much debate. In some taxa the costs …
