Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Shoreline oiling effects and recovery of salt marsh macroinvertebrates from the Deepwater Horizon Oil Spill [PDF]
PeerJ, 2017 Salt marshes in northern Barataria Bay, Louisiana, USA were oiled, sometimes heavily, in the aftermath of the Deepwater Horizon oil spill. Previous studies indicate that fiddler crabs (in the genus Uca) and the salt marsh periwinkle (Littoraria irrorata)

Fiddlers on the roof: elevation muddles mate choice in fiddler crabs [PDF]
Behavioral Ecology, 2014 Biological signaling usually occurs in complex environments, yet signals are most often studied in controlled experiments that strip away this complexity. Male fiddler crabs possess one enlarged claw that is waved during courtship displays, and females preferentially respond to larger claws and faster waves.

Benthic bioturbations weaken the stability of blue carbon storage
National Science OpenCoastal ecosystems are known for their ability to sequester organic carbon (OC), termed “blue carbon”. The molecular composition of dissolved organic matter (DOM) can affect sediment OC content; however, the impact of benthic bioturbation on DOM ...

Unidirectional Optomotor Responses and Eye Dominance in Two Species of Crabs
Frontiers in Physiology, 2019 Animals, from invertebrates to humans, stabilize the panoramic optic flow through compensatory movements of the eyes, the head or the whole body, a behavior known as optomotor response (OR).

Acta Zoologica, Volume 107, Issue 4, Page 450-459, October 2026.ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Ecology and Evolution, Volume 16, Issue 9, September 2026.We investigated niche divergence among Aegla clades of freshwater crustaceans from southern South America. Results show distinct climatic preferences with low overlap, rejecting conservatism and linking ecology to diversification, highlighting niche divergence driving freshwater biodiversity.

Zoologia (Curitiba), 2009 A population of the fiddler crab Uca rapax (Smith, 1870) found in Itaipu Lagoon, southeast Brazil, was sampled monthly from July 2006 to June 2007 in order to study population and reproductive features.
