Predicting diet in brachyuran crabs using external morphology [PDF]
PeerJ, 2023 Morphological traits have often been used to predict diet and trophic position of species across many animal groups. Variation in gut size of closely related animals is known to be a good predictor of dietary habits.

Contrasting population genetic structure of three semi‐terrestrial brachyuran crabs on the coast of the Japanese archipelago [PDF]
Ecology and EvolutionAnthropogenic activities have reduced ecotones between the ocean and land, which is likely to threaten the population of brackish‐water brachyuran crabs.

Planes on a Snake? On the Identities of Crab Larvae Rafting on Sea Snakes [PDF]
Ecology and EvolutionRafting on surface‐drifting flotsam or pelagic animals may represent an important behavioral strategy for larval transport and recruitment among brachyuran crabs.

Morphometric correlations between dietary and reproductive traits of two brachyuran crabs, Hemigrapsus sanguineus and Aratus pisonii [PDF]
PLoS ONE, 2022 Many animals have flexible morphological traits that allow them to succeed in differing circumstances with differing diets available to them. For brachyuran crabs, claw height and gut size are diet-specific and largely reflect foraging strategies, while ...

The mitogenome of the crab Grapsus adscensionis (Osbeck, 1765) [PDF]
Mitochondrial DNA. Part B. ResourcesThe mitochondrial genome of Grapsus adscensionis (Osbeck, 1765), a rocky shore crab distributed across the Macaronesian archipelagos and the eastern Atlantic, was sequenced and annotated for the first time.

Ecological and evolutionary implications of allometric growth in stomach size of brachyuran crabs. [PDF]
PLoS ONE, 2018 Individual characteristics often scale allometrically with organismal body size and the form of this scaling can be influenced by ecological and evolutionary factors. Examining the specific form of this scaling can therefore yield important insights into

Mangrove Rehabilitation and Brachyuran Crab Biodiversity in Ranong, Thailand
DiversityMangroves rehabilitated after deforestation by commercial exploitation must be monitored to confirm that key ecosystem functions are being restored.

Conserved Gene Order and Adaptive Evolution in Mitochondrial Genomes of <i>Calappa</i> Crabs: Insights Into Ecological Specialization and Phylogenetic Utility. [PDF]
Ecol EvolThis 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 of Cheliped Autotomy and Regeneration in the Lower Miocene Crab <i>Achelous monspeliensis</i> From Portugal. [PDF]
Ecol EvolCrab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...
