Male genitalia show patterns of divergent evolution, and sexual selection is recognised as
being responsible for this taxonomically widespread phenomenon. Much of the empirical …

Phenotypic plasticity in general and polyphenic development in particular are thought to
play important roles in organismal diversification and evolutionary innovation. Focusing on …

Alternative reproductive tactics (ARTs) coexisting within a population are found in many
organisms. Their existence has been an enduring puzzle in evolutionary biology. Why …

Male genital morphology is characterized by two striking and general patterns of
morphological variation: rapid evolutionary divergence in shape and complexity, and …

Phenotypic plasticity allows organisms to cope with rapid environmental change. Yet exactly
when during ontogeny plastic responses are elicited, whether plastic responses produced in …

The male genitalia of arthropods consistently show negative static allometry (the genitalia of
small males of a species are disproportionally large, and those of large males are …

Many dung beetle communities are characterized by species that share very similar
morphological, ecological, and behavioral traits and requirements yet appear to be stably …

Many important questions in developmental biology increasingly interface with related
questions in other biological disciplines such as evolutionary biology and ecology. In this …

Feeding habits are important life-history traits in animals; however, methods for their
determination are not well established in many species. The larvae of the beetle family …

Genitalia are among the fastest evolving morphological traits in arthropods. Among the
many hypotheses aimed at explaining this observation, some explicitly or implicitly predict …
