The first edition of Geometric Morphometrics for Biologists has been the primary resource for
teaching modern geometric methods of shape analysis to biologists who have a stronger …

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 …

Grapsus grapsus and Grapsus adscensionis are supralittoral crabs that are known to inhabit
oceanic islands and depend on surface currents to recruit in the rocky shores. The …

Sexual dimorphism is often observed in Crustaceans. Considering the great diversity of this
subphylum, only few reports are found in the literature and most are mainly based on …

The fiddler crab Tubuca arcuata (Crustacea: Ocypodidae: Gelasiminae) is widely distributed
across East Asia and northern Vietnam. Particularly, this species inhabits estuarine …

Species across the planet are shifting or expanding their ranges because of climate change.
These are climate migrants. Although climate migrants are well documented, their impacts …

Understanding how biological patterns translate into functional processes across different
scales is a central question in ecology. Within a spatial context, extent is used to describe …

The freshwater crab Potamon persicum in Iran is distributed along the western Alborz
Mountains, its range extending southeast through the whole Zagros Mountains. We …

Although discordance between taxonomic diversity and morphological disparity is common,
little is known about the underlying dynamics that drive this decoupling. Early in the history …

Genetic divergences among populations of Aegla longirostri suggest that this group may be
formed by cryptic species. In this study, we analysed the carapace shape of six populations …
