Males in many species invest substantially in structures that are used in combat with rivals
over access to females. These weapons can attain extreme proportions and have diversified …

With their eyes on long vertical stalks, their panoramic visual field and their pronounced
equatorial acute zone for vertical resolving power, the visual system of fiddler crabs is …

Insects display a staggering diversity of mating and social behaviours. Studying these
systems provides insights into a wide range of evolutionary and behavioural questions, such …

The costs of reproduction in brachyurans are reviewed. In both sexes a number of aspects of
reproductive behaviour and physiology can result in higher mortality and/or slower growth …

Background The transition from water to air is a key event in the evolution of many marine
organisms to access new food sources, escape water hypoxia, and exploit the higher and …

The Asian shore crab, Hemigrapsus sanguineus, is native to coastal and estuarine habitat
along the east coast of Asia. The species was first observed in North America near Delaware …

In intertidal systems, the type and role of interactions among sediment microorganisms,
animals, plants and abiotic factors are complex and not well understood. Such interactions …

The current phylogenetic hypothesis for the evolution and biogeography of fiddler crabs
relies on the assumption that complex behavioral traits are assumed to also be evolutionary …

By examining the morphological basis of force generation in the chelae (claws) of both
molluscivorous and non-molluscivorous crabs, it is possible to understand better the …

Herein I present a brief review of biased sex ratios in fiddler crabs and examine a limited
data set involving a population of Uca pugilator (Bosc, 1802) to explore causes of such …
