Spatial distribution and population structure of fiddler crabs in an Indian Sundarban mangrove

open access: yesScientia Marina, 2015
Brachyuran crabs constitute the most abundant faunal component of mangrove ecosystems and support a wide range of ecosystem services. In the present study, seasonal variation of population density and biomass along with demographic categories and sex ...

The early Pleistocene whale-fall community of Bargiano (Umbria, Central Italy): Paleoecological insights from benthic foraminifera and brachyuran crabs

open access: yes, 2018
New insights into communities of benthic foraminifera and decapods, associated with whale-fall events (WFE) in a relatively shallow sea environment, are reported here for the first time from the early Pleistocene of Bargiano (southwestern Umbria, Italy).

Description of the first juvenile stage of Dilocarcinus septemdentatus (Herbst, 1783) (Crustacea, Decapoda, Trichodactylidae)

open access: yesNauplius, 2017
A total of 38 freshwater brachyuran species occur in Brazil, of which 79% are distributed in the northern region. However, for only two species of freshwater crabs are descriptions available for their juveniles.

Constraint on Reproductive Output in Brachyuran Crabs: Pinnotherids Test the Rule [PDF]

open access: yesAmerican Zoologist, 1992
Brood weight and number of eggs per brood are primarily determined by female body size in brachyuran crabs. Brood weight exhibits an isometric relationship spanning more than four orders of magnitude in body weight among 33 non-pinnotherid species, with brood size being constrained to about 10% of female body weight by the space available for yolk ...

A 150-million-year-old crab larva and its implications for the early rise of brachyuran crabs

open access: yesNature Communications, 2015
True crabs (Brachyura) are the most successful group of decapod crustaceans. This success is most likely coupled to their life history, including two specialised larval forms, zoea and megalopa.

Visual Displays in Brachyuran Crabs: Field and Laboratory Studies [PDF]

open access: yesAmerican Zoologist, 1968
Study of the visual displays of more than 30 species of crabs allows some generalizations on the Brachyrhyncha. The displays fall into two groups, the Lateral Merus and the Chela Forward. Each group contains three major subtypes of display, which originated as discrete signals of intensity.

open access: yes, 2015
Almost 50 years have passed since a group of reputed carcinologists (viz. Lipke B. Holthuis, Isabella Gordon and Jacques Forest) finished the posthumous work of Ricardo Zariquiey Alvarez (1968) on decapod crustaceans of the Iberian Peninsula. No lists of
