Rensch's rule, a well-studied macroevolutionary pattern of sexual size dimorphism (SSD), predicts, in monophyletic taxa in which males are the larger sex, that as the body size of the species in the ...

Sexual conflict has been shown to shape many behaviors in the reproductive context, such as the duration of copulation, across a broad taxonomic range. In spiders, copulation duration is one of the ...

When sexual conflict results in reproductive strategies that only benefit one of the sexes, it may result in evolutionary arms races. Male spiders have evolved behavioural mating strategies to improve ...

New research has disabused Spider scientists (technical term, I assure you) at the Smithsonian of a long-standing misconception that males of the “highly sexually dimorphic and polygamous” wink, wink, ...
