Exploring carapace phenotypic variation in female Fiddler Crab (H. Milne Edwards, 1837): insights into adaptive strategies and ecological significance

open access: yesJournal of Threatened Taxa
Fiddler crabs (Ocypodidae: Crustacea: Arthropoda) are globally documented but relatively understudied along the Indian coastline. Austruca annulipes, common across Indian mangrove habitats, remains insufficiently explored in terms of female morphology ...

Estimating the size of Uca tangeri (Crustacea: Ocypodidae) without massive crab capture

open access: yesScientia Marina, 2000
Uca tangeri (Eydoux, 1835) is the only species of fiddler crab that occurs in Portugal, where it mainly inhabits salt marshes in the south and southwest coasts.

N2 fixation dominates nitrogen cycling in a mangrove fiddler crab holobiont

open access: yesScientific Reports, 2020
Mangrove forests are among the most productive and diverse ecosystems on the planet, despite limited nitrogen (N) availability. Under such conditions, animal-microbe associations (holobionts) are often key to ecosystem functioning.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

open access: yesActa 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 ...

Niche Divergence in the South American Freshwater Crustacean Aegla Provides Insights Into Its Diversification

open access: yesEcology 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.

Hemigrapsus sanguineus in Long Island salt marshes: experimental evaluation of the interactions between an invasive crab and resident ecosystem engineers [PDF]

open access: yesPeerJ, 2014
The invasive Asian shore crab, Hemigrapsus sanguineus, has recently been observed occupying salt marshes, a novel environment for this crab species. As it invades this new habitat, it is likely to interact with a number of important salt marsh species ...

Climatic niche divergence and high‐elevation adaptation promoted rapid diversification of Pimoa spiders in Pan‐Himalaya

open access: yesEcography, Volume 2026, Issue 9, September 2026.
The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across three major mountain regions: the Rockies, the Alps, and the Pan‐Himalaya ...

CHIMNEY BUILDING IN THE FIDDLER CRAB UCA ARCUATA [PDF]

open access: yesJournal of Crustacean Biology, 2000
Abstract The fiddler crab Uca arcuata (De Haan, 1835), which lives on intertidal mud flats, occasionally builds a cylindrical mud chimney that encircles its burrow entrance. Chimneys were more often found with burrows of females than with those of males (22% versus 10%).

Effects of Fiddler Crab Burrows on Sediment Properties in the Mangrove Mudflats of Sungai Sepang, Malaysia

open access: yesBiology, 2016
In mangrove ecosystems, litter fall accumulates as refractory organic carbon on the sediment surface and creates anoxic sediment layers. Fiddler crabs, through their burrowing activity, translocate oxygen into the anoxic layers and promote aerobic ...
