Handedness in fiddler crab fights [PDF]

, 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

Microplastic Presence in the Mangrove Crab Ucides occidentalis (Brachyura: Ocypodidae) (Ortmann, 1897) Derived From Local Markets in Tumbes, Peru

Air, Soil and Water Research, 2022
In northern Peru, the mangrove crab Ucides occidentalis is of great importance due to its ecological, economic, and social role. In this study, we reported for the first time the presence of microplastics in the gills and digestive tract of the mangrove ...

MATING BEHAVIOR OF UCA LACTEA PERPLEXA (DECAPODA: OCYPODIDAE) [PDF]

Journal of Crustacean Biology, 1998
Some fiddler crab species (genus Uca) are known to mate either on the surface or underground. Here we describe these two modes of mating in Uca lactea perplexa and compare them with these mating modes in other ocypodid crabs. All surface matings, which lasted from 1.2-5.1 min, occurred near the burrow entrance of the female.

The effect of crab burrows on soil‐water dynamics in mangroves

Hydrological Processes, Volume 36, Issue 3, March 2022., 2022
Abstract Many mangrove ecosystem services, such as carbon sequestration, are closely linked to mangrove soil water content, which in turn is thought to depend on animal burrow density and the properties of the sediment in which the burrows are constructed.

Complete mitogenome of Uca rosea and Uca paradussumieri, and their implications in evolution history of fiddler crab in Ocypodidae

Mitochondrial DNA. Part B. Resources, 2020
We determined the complete mitogenomes of two fiddler crabs Uca rosea (15,643 bp) and Uca paradussumieri (15,614 bp) of Ocypodidae within Brachyura. Both consist of 37 genes (13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes ...

The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura [PDF]

, 2017
We sequenced the mitochondrial genomes of the spider crabs Maja crispata and Maja squinado (Majidae, Brachyura). Both genomes contain the whole set of 37 genes characteristic of Bilaterian genomes, encoded on both \u3b1- and \u3b2-strands.

Specialized Feeding Patterns and Marine Resource Use by Nonnative Catfishes in a Coastal River Ecosystem Revealed by Dietary and Stable Isotopic Analyses

Marine and Coastal Fisheries, Volume 13, Issue 5, Page 564-582, October 2021., 2021
Abstract Two large predatory catfishes, the Flathead Catfish Pylodictis olivaris and Blue Catfish Ictalurus furcatus, have been introduced into multiple U.S. Atlantic slope drainages in recent decades, with concomitant reductions in native fish abundance and changes in faunal community composition.

Density, structure, growth, and mortality of the population of Ocypode gaudichaudii H. Milne Edwards & Lucas, 1843 (Brachyura, Ocypodidae) in Salaverry, Peru

Crustaceana, 2023
The northern coast of Peru includes a series of dissipative desert beaches with varying levels of human impact. One endemic species to these beaches is Ocypode gaudichaudii, which has been shown to be an indicator of ecosystem disturbance.

Comparison of the population structure of the fiddler crab Uca vocator (Herbst, 1804) from three subtropical mangrove forests

Scientia Marina, 2004
The population structure of U. vocator was investigated during a one-year period in three mangrove forests in southeast Brazil. The study specifically addressed comparisons on individual size , juvenile recruitment and sex-ratio.

Growth of the Mangrove Crab Ucides Cordatus (Brachyura, Ocypodidae) [PDF]

Journal of Crustacean Biology, 2005
Abstract During monthly samplings between September 1998 and August 2000, 3,660 specimens of Ucides cordatus (Linnaeus, 1763) (2054 males and 1606 females) were obtained and examined for size (CW = carapace width) to determine growth-age equations for each sex.
