Handedness in fiddler crab fights [PDF]
Animal Behaviour, 2015 Asymmetric weapons are common in bilateral animals and, in some species, they can occur on either the left- or the right-hand side of the body (lateralization). Fiddler crabs (Uca spp, Decapoda: Ocypodidae) have an enlarged claw that is used in male–male

Territorial battles between fiddler crab species [PDF]
Royal Society Open Science, 2017 Many species worldwide are impacted by habitat loss. This may result in increased competition both within species and between species. Many studies have demonstrated that when two previously non-overlapping species are forced to compete over a resource ...

Ladies First: Coerced Mating in a Fiddler Crab. [PDF]
PLoS ONE, 2016 In some species males increase their reproductive success by forcing females to copulate with them, usually by grasping the female or pinning her to the ground to prevent her from escaping.

The fiddler crab, Minuca pugnax, follows Bergmann's rule [PDF]
Ecology and Evolution, 2019 Bergmann's rule predicts that organisms at higher latitudes are larger than ones at lower latitudes. Here, we examine the body size pattern of the Atlantic marsh fiddler crab, Minuca pugnax (formerly Uca pugnax), from salt marshes on the east coast of ...

A spatially explicit model of synchronization in fiddler crab waving displays. [PDF]
PLoS ONE, 2013 Fiddler crabs (Uca spp., Decapoda: Ocypodidae) are commonly found forming large aggregations in intertidal zones, where they perform rhythmic waving displays with their greatly enlarged claws.

Reduced genetic diversity and alteration of gene flow in a fiddler crab due to mangrove degradation. [PDF]
PLoS One, 2017 The fiddler crab Austruca occidentalis is a dominant species in mangrove forests along the East African coast. It enhances soil aeration and, through its engineering activities, makes otherwise-inaccessible food available for other marine organisms ...

N2 fixation dominates nitrogen cycling in a mangrove fiddler crab holobiont [PDF]
Scientific 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.
