Morphological Variation of the Fiddler Crab Tubuca paradussumieri (Decapoda: Ocypodidae) Among Provinces in the Vietnamese Mekong Delta and a Classification Key for Genus Tubuca

International Journal of Zoology
Although Tubuca paradussumieri​ (Decapoda: Ocypodidae) is an essential species in tropical mangrove ecosystems, little is known about how its intraspecific morphology varies depending on the habitat.

<i>Planes</i> on a Snake? On the Identities of Crab Larvae Rafting on Sea Snakes. [PDF]

Ecol Evol
We sequenced COI and 16S rRNA genes from 106 crab megalopae found rafting on the pelagic sea snake Hydrophis platurus to test whether they were the obligate rafting species Planes minutus. Instead, all larvae belonged to three inter‐ to supratidal grapsid crabs—Pachygrapsus socius, Goniopsis pulchra, and Grapsus grapsus—revealing no evidence of Planes.

Conserved Gene Order and Adaptive Evolution in Mitochondrial Genomes of <i>Calappa</i> Crabs: Insights Into Ecological Specialization and Phylogenetic Utility. [PDF]

Ecol Evol
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.

Population Dynamics of the Fiddler Crab <i>Tubuca rhizophorae</i> (Tweedie, 1950) in the Mekong Delta, Vietnam. [PDF]

Ecol Evol
This study uses monthly field surveys and length‐frequency analysis to examine the population dynamics of the fiddler crab Tubuca rhizophorae in the Mekong Delta, Vietnam. Key parameters, including growth rate, mortality, and exploitation rate, were estimated, revealing that the species experiences rapid growth but is subject to significant fishing ...

Fiddler Crabs (Crustacea: Decapoda: Ocypodidae) From Coastal Ecuador and the Galápagos Islands: Species Descriptions and DNA Barcodes. [PDF]

Ecol Evol
Twenty‐five taxa were collected during the surveys, while two more were noted from the literature and museum collections; five are new to Ecuador. DNA sequences for cytochrome c oxidase–subunit 1 were obtained for 27 operational taxonomic units with three morphologically indistinguishable cryptic or pseudo‐cryptic taxa were also revealed.

Intraspecific Sensory Diversity and the Decapod Claw: Patterns of Sensillation Are Heterochelic and Sexually Dimorphic In Pagurus bernhardus. [PDF]

J Morphol
Information detection is crucial for biological life, yet many aspects of sensory diversity remain underexplored. Using Pagurus bernhardus hermit crabs, we examined intraspecific sensory diversity in chelar morphology. Examinations of scanning electron micrographs of chelar moults by geometric morphometric analyses and linear mixed modelling revealed ...

Complete mitogenome of Uca rosea and Uca paradussumieri, and their implications in evolution history of fiddler crab in Ocypodidae

Mitochondrial DNA. Part B. Resources, 2020
We determined the complete mitogenomes of two fiddler crabs Uca rosea (15,643 bp) and Uca paradussumieri (15,614 bp) of Ocypodidae within Brachyura. Both consist of 37 genes (13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes ...

The microbial landscape in bioturbated mangrove sediment: A resource for promoting nature‐based solutions for mangroves

Microbial Biotechnology, Volume 16, Issue 8, Page 1584-1602, August 2023., 2023
Bioturbation, through altering the sediment microbiome and environment, determining a “halo effect”, can ameliorate conditions for plant growth, highlighting the potential of the mangrove microbiome as a nature‐based solution to sustain mangrove development and support the role of this ecosystem to deliver essential ecological services.

Comparison of the population structure of the fiddler crab Uca vocator (Herbst, 1804) from three subtropical mangrove forests

Scientia Marina, 2004
The population structure of U. vocator was investigated during a one-year period in three mangrove forests in southeast Brazil. The study specifically addressed comparisons on individual size , juvenile recruitment and sex-ratio.

Morphology of the gastric mill teeth in dotillid crabs (Crustacea: Brachyura: Dotillidae) from Indonesia

Journal of Morphology, Volume 284, Issue 7, July 2023., 2023
Among deposit‐feeder crab, the morphology of the gastric mill teeth is well correlated with the substrate types. We provide descriptions of the morphology of the median and lateral teeth on gastric mills in eight species of dotillid crabs with phylogenetic analysis using COI and 16S rRNA genes.
