The family Ocypodidae is a group of intertidal brachyuran crabs found in tropical to
temperate seas worldwide. While the family has historically included many subfamilies, most …

Because of its simplicity, the binary-switch nature of left-right asymmetry permits meaningful
comparisons among many different organisms. Phylogenetic analyses of asymmetry …

Phylogenetic generalised least squares (PGLS) is one of the most commonly employed
phylogenetic comparative methods. The technique, a modification of generalised least …

META-ANALYSIS USES SUMMARY STATISTICS like effect sizes to combine information
from multiple studies. Yet a common problem encountered when collecting information for …

For decades, the extreme asymmetric chelipeds of male fiddler crabs (genus Uca) have
been used as a model system for the description and discussion of allometry. Almost all …

To assess and analyse accurately their geographical distributions, fiddler crabs (Uca) from
the Atlantic coast of Brazil were studied using field collections, museum specimens and …

Despite growing interest in species' range shifts, little is known about the ecological and
evolutionary factors that control geographic range boundaries. We investigated the …

Un total de 403 especies de crustáceos decápodos y 15 de estomatópodos se han
registrado para el mar, las costas y las aguas continentales peruanas. Por efecto de eventos …

Male fiddler crabs, genus Uca, have one greatly enlarged claw with which they court
females and threaten and fight other males. Longer claws are more effective signals but are …

The field of left–right (LR) patterning—the study of molecular mechanisms that yield directed
morphological asymmetries in otherwise symmetrical organisms—is in disarray. On one …
