Latitudinal gradient in niche breadth of brachyuran crabs

Global Ecology and Biogeography, 2015
AbstractAimNiche breadth has long been hypothesized to decrease at low latitudes and contribute to global patterns of species diversity. Range size, phylogenetic relatedness and body size also have hypothesized relationships with both latitude and niche breadth, which may further affect niche breadth patterns. Existing terrestrial data are inconclusive

Dietary and Reproductive Traits of Two Brachyuran Crab Species

2022
Abstract 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 abdomen width reflects relative levels of fecundity ...

The Monophyly of Brachyuran Crabs: A Phylogenetic Study Based on 18S rRNA

Systematic Biology, 1992
A molecular approach was used to test hypotheses about the phylogeny of selected brachyuran crabs. Partial 18S ribosomal (r) RNA and rDNA sequences, ranging in length from 950 to 1,779 nucleotides, were obtained for 12 decapod crustaceans, 10 of which are generally considered to be brachyurans. Pairwise sequence-divergence estimates ranged from 0.5% to

Effects of Manipulated Diet on Size and Performance of Brachyuran Crab Claws

Science, 1994
Crabs grown experimentally on fully shelled prey developed larger and stronger claws than those raised on nutritionally equivalent unshelled prey. When one claw was immobilized, claws also became asymmetrical. These use-induced changes differ from skeletal remodelling in vertebrates and many invertebrates because changes in the rigid exoskeleton can ...

The megalopa stage in brachyuran crabs. The Podotremata Guinot

Journal of Natural History, 1981
Summary The available information on the megalopa stage in podotrematous crabs, that is the Dromioidea, Homoloidea, Raninoidea and Tymoloidea, is reviewed. The morphology of the megalopas tends to support the relationships between these groups indicated by the zoeal stages but does not provide any additional evidence on the unresolved problem of ...
