Many investigators use the reduced major axis (RMA) instead of ordinary least squares
(OLS) to define a line of best fit for a bivariate relationship when the variable represented on …

Classic explanations of variation in mating systems critically depend on variation in
demography. Here, we emphasize how understanding dynamic links between fluctuating …

Across a variety of animal taxa, the outcome of male–male contests depends on male body
size; winners are usually the larger males or the males with bigger weapons. However, high …

Male mate choice is expected in species in which future mating opportunities of males are
strongly diminished after their first copulation and mate quality is variable unless the costs of …

Risk assessment is a fundamental component of any decision-making process, including
mate choice. For males, one element of risk that is rarely considered is that a female mate …

Introduction Male monogyny in the absence of paternal investment is arguably one of the
most puzzling mating systems. Recent evidence suggests that males of monogynous …

Behavioural decisions involving foraging, mate choice and habitat selection are complex
and difficult to evaluate experimentally. Web abandonment by orb spiders is a complex …

Insects are predicted to prefer larger partners for a number of reasons relating to fitness. In
species where males provide an expensive nuptial gift, male and female preferences for a …

Spider webs, and in particular orb webs, are among the most iconic characteristics of spider
biology. The evolution of, and developmental changes in, orb webs have been well studied …

Sexual selection is a process that operates through intrasexual competition and intersexual
choice for reproduction in both sexes. Here, we report our work on a polygamous moth …
