The activity pattern of intertidal crabs is influenced by factors that usually change rhythmically following tidal and/or diel cycles, and is often associated with the use of refuges. The movement activity of the burrowing crab Neohelice granulata was compared among three populations from SW Atlantic coastal areas where they face different tidal regimes, water salinities, substrata and biological factors. At each site, we examined the seasonal activity of the crabs (individuals collected in… 

Influence of tidal regime, diurnal phase, habitat and season on feeding of an intertidal crab

Both diet and feeding activity of this crab seem to be flexible traits adapted to different combinations of physical and biological factors, which varied according to spatial and/or temporal changes in some natural cycles.

Burrowing activity of the Neohelice granulata crab (Brachyura, Varunidae) in southwest Atlantic intertidal areas

Differences in burrow features and burrow activity of N. granulata between microhabitats were confirmed and associated with biotic and abiotic factors, indicating that this species has an adaptive burrowing behavior.

Habitat selection of the mud crab Rhithropanopeus harrisii in its newly invaded range

A habitat selection experiment with P. australis and F. vesiculosus habitats and varying food availability, and found that R. harrisii preferred the shelter of the rock habitat, indicating that the North American mud crab choose their habitat based on habitat structure rather than food availability in the habitat.

Temperature influences the reproduction of fiddler crabs at the southern edge of their distribution

Temperature was the environmental factor that was most correlated with the reproductive process of the southernmost fiddler crab, since this environmental factor was related to ovarian development, to the fullness of seminal receptacles, and to the hepatosomatic index.

Hatching and larval export of the intertidal crab Neohelice granulata in Mar Chiquita coastal lagoon, Argentina

It is found that ovigerous females of N. granulata have a marked synchronization in embryonic development which results in that most of berried females are close to hatching within a period of maximum tidal range (days), governed by environmental conditions.

Site fidelity and population structure of blue land crabs (Cardisoma guanhumi Latreille, 1825) in a restricted-access mangrove area, analyzed using PIT tags

Understanding the patterns of displacement and site fidelity in blue land crabs (Cardisoma guanhumi Latreille, 1825) has important implications for their conservation and management. The central

Life history of the sesarmid crab, Clistocoeloma villosum, on the southern coast of the Izu Peninsula, central Japan

We investigated the life history traits of a population of the sesarmid crab, Clistocoeloma villosum on the southern coast of Izu Peninsula, the known eastern range limit of the species distribution.

Effect of Feeding Technique and Prey Characteristics on the Feeding Rate of Olrog's Gulls (Larus atlanticus)

Olrog's Gulls used four feeding techniques, with more prey captured by pecking than by peck-digging, head submergence, or up-ending, and feeding rate increased with average prey density and was higher when feeding in structured environments.

Population Structure of the SW Atlantic Estuarine Crab Neohelice granulata Throughout Its Range: a Genetic and Morphometric Study

The genetic structure of this species could be divided into two distinct groups due to a limited gene flow between southern and northern regions as a consequence of larval dispersal patterns and the morphometric analysis showed no geographical pattern of morphological differentiation, although there were differences among sampling sites.
