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

open access: yesZoologica Scripta, Volume 55, Issue 3, Page 504-518, May 2026.
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

open access: yesJournal 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 ...

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, Volume 2026, Issue 4, April 2026.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

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

open access: yesScientific 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

open access: yesFrontiers 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:

Classification, Biodiversity and Conservation of Marine Commercial Crabs of India [PDF]

open access: yes, 2017
One of the best known and most intensely studied groups is the true crabs of the infraorder Brachyura. Brachyuran crabs belong to the Order Decapoda, the most diverse group of crustaceans alive today (Ng et al., 2008).
