Spatiotemporal distribution and abundance of mangrove ecosystem engineers: burrowing crabs around canopy gaps [PDF]
The burrowing and feeding activities of fiddler and sesarmid crabs have considerable impacts on ecosystem functioning, accordingly they are considered ecosystem engineers.

Predation risk modifies behaviour by shaping the response of identified brain neurons [PDF]
Interpopulation comparisons in species that show behavioural variations associated with particular ecological disparities offer good opportunities for assessing how environmental factors may foster specific functional adaptations in the brain.

The functions of multiple visual signals in a fiddler crab
23 24 In many species, it is common for animals to have multiple signals within one channel of 25 communication. Multiple signals may, however, be inefficient if they are redundant in nature.

Burrow morphology of three species of fiddler crab (Uca) along the coast of Pakistan
Burrowing by crabs is an important component of their functional role in mangrove biotopes. The Fiddler crab (Uca) is one of the more conspicuous burrowing organisms in the mangrove areas of Pakistan.

CHIMNEY BUILDING IN THE FIDDLER CRAB UCA ARCUATA [PDF]
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%).

Target Detection Is Enhanced by Polarization Vision in a Fiddler Crab [PDF]
We are constantly surprised by the ability of relatively simple animals to perform precise visually guided movements within complex visual scenes, often using eyes with limited resolution. Exceptional examples include the capture of airborne prey by dragonflies, the learning flights of bees and wasps, and the tracking of conspecifics by crabs on ...

Fiddler crab (Uca spp.) belongs to the Order Decapoda and Family Ocypodidae, which live by making burrows in the substrate between mangrove plants. The presence of fiddler crabs plays an important role in mangrove ecosystems, which can increase sediment ...

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