Occurrence of Arboreal-climbing Grapsids and Other Brachyurans in Two Mangrove Areas of Southern Luzon, Philippines [PDF]

, 2011
Despite the obvious importance to ecosystem functioning, the most prominent groups belonging to the Grapsidae are generally regarded as less studied in the Philippines.

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

Acta Zoologica, EarlyView.
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 ...

Molecular Phylogeny, Species Delimitation, and Biogeography of the Varunid Crab Genus Metaplax (Crustacea, Varunidae)

Zoologica Scripta, EarlyView.
ABSTRACT The Indo‐West Pacific genus Metaplax comprises 11 recognised species inhabiting intertidal mudflats, some adjacent to mangroves. To resolve long‐standing uncertainties, we analysed mitochondrial (COI, 16S) and nuclear (28S) markers. Phylogenetic analyses recovered Metaplax as monophyletic and resolved four well‐supported clades—the M ...

Metabolomic analysis of secondary metabolites from Caribbean crab gills using comprehensive two-dimensional gas chromatography - time-of-flight mass spectrometry—New inputs for a better understanding of symbiotic associations in crustaceans

Journal of Chromatography Open, 2022
Secondary metabolites are bioactive compounds produced by living organisms that can be indicative of symbiotic relationships in nature. Prior studies have demonstrated putative symbiotic interactions between decapod crabs and epibiotic bacteria in their ...

Conserved Gene Order and Adaptive Evolution in Mitochondrial Genomes of Calappa Crabs: Insights Into Ecological Specialization and Phylogenetic Utility

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study presents the first complete mitochondrial genomes of five Calappa species, filling a critical gap in genomic resources for the family Calappidae. Our analyses confirm the monophyly of Calappidae, detect positive selection in key energy metabolism genes (ATP6, ND2, ND5), and reveal conserved gene arrangement patterns.

Evidence for use of both capital and income breeding strategies in the mangrove tree crab, Aratus pisonii

Scientific Reports, 2021
Two common strategies organisms use to finance reproduction are capital breeding (using energy stored prior to reproduction) and income breeding (using energy gathered during the reproductive period). Understanding which of these two strategies a species

Reproductive Traits of the Vent Crab Segonzacia mesatlantica (Guinot, 1989) From the Mid-Atlantic Ridge

Frontiers in Marine Science, 2022
Characteristics of the life-history biology of hydrothermal vent species are a prerequisite to understanding the dispersal, population connectivity, and ecology of these insular populations. The vent crab Segonzacia mesatlantica (Guinot, 1989; Brachyuran:

Checklist of brachyuran crabs (Crustacea: Decapoda) from the eastern tropical Pacific [PDF]

, 1995
Literature dealing with brachyuran crabs from the east Pacific is reviewed. Marine and brackish water species reported at least once in the Eastern Tropical Pacific zoogeographic subregion, which extends from Magdalena Bay, on the west coast of Baja ...

A review of autonomous reef monitoring structures (ARMS) for monitoring hard‐bottom benthic biodiversity

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 435-455, February 2026.
Abstract Amid increasing anthropogenic pressures on ecosystems, standardised biodiversity monitoring is critical for assessing biodiversity change. Marine hard‐bottom habitats, though ubiquitous and biodiverse, present challenges for biodiversity monitoring due to their complex structure and limited accessibility. Autonomous reef monitoring structures (
