Juvenile development of Callinectes danae Smith, 1869 (Crustacea, Decapoda, Brachyura, Portunidae) under laboratory conditions [PDF]

open access: yesAnais Da Academia Brasileira De Ciencias, 2014
The juvenile development of Callinectes danae was investigated from megalopae obtained in neuston samples at Ubatuba, São Paulo, Brazil. The individuals were raised in the laboratory under constant temperature (25 ± 1°C), filtered sea water from the ...

Species which may act as vectors or reservoirs of diseases covered by the Animal Health Law: Listed pathogens of crustaceans. [PDF]

open access: yesEFSA J, 2023
Abstract Vector or reservoir species of three diseases of crustaceans listed in the Animal Health Law were identified based on evidence generated through an extensive literature review, to support a possible updating of Regulation (EU) 2018/1882.

Amino acid nitrogen and carbon isotope data: Potential and implications for ecological studies. [PDF]

open access: yesEcol Evol, 2022
Stable isotope analysis of individual amino acids (AAs) in natural abundance is now emerging as a promising and complementary method to characterize the flow and transformation of resources across a diversity of organisms, from microbial domains to macroscopic consumers. Many empirical ecologists are still unfamiliar with the scope of applicability and

Macrogenetics Approach Reveals Spatial Trends and Drivers of Mitochondrial Genetic Diversity at Different Biological Organization Levels in Tropical Western Atlantic Decapods. [PDF]

open access: yesEcol Evol
There is a knowledge gap concerning the genetic diversity distribution across marine invertebrates, and whether the latitudinal genetic diversity gradient results from congruent intraspecific trends. Our results indicate higher genetic diversity in lower latitudes is correlated to productivity and oxygen levels, but does not represent the accumulation ...

All or nothing: Switch to high current reproductive investment under risk of starvation in male kelp crab. [PDF]

open access: yesEcol Evol, 2020
In this study, we demonstrate plasticity in recovery of seminal reserves in response to distinct environmental conditions in the kelp crab Taliepus dentatus. We show that the recovery index at 16°C within 30 days was twice as high in starved compared with fed crabs.

Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives. [PDF]

open access: yesAquac Nutr
Reproductive maturation remains a central bottleneck in crustacean aquaculture, as ovarian development dictates broodstock quality, fecundity, and larval viability. This review synthesizes current knowledge on the physiological regulation of ovarian maturation in decapod crustaceans, emphasizing the interplay of hormones, nutrients, and environmental ...

De Novo Transcriptome Assembly Reveals Insights Into Osmoregulation and Oxidative Stress Response in the Gills of the Southern King Crab (<i>Lithodes santolla</i>). [PDF]

open access: yesEcol Evol
The Southern King Crab (Lithodes santolla), an ecologically and commercially important species in sub‐Antarctic waters. In this study, we assembled the first gill de novo transcriptome of L. santolla to characterize gene expression related to environmental responses.

Do the day/night periods and tidal cycles modulate the abundance and distribution of Callinectes danae Smith, 1869 (Brachyura, Portunidae) in an estuary-bay complex from southeastern Brazil?

open access: yesNauplius, 2020
We investigated the abundance and spatial distribution of Callinectes danae Smith, 1869 during the day/night periods and tidal cycles in a coastal area of Brazil. Sex ratio, size class distribution, and mean sizes of males and females were also analyzed.

Carapace width/length-weight relationships for portunid crabs (genus Callinectes Stimpson, 1860) in northern Brazilian mangrove estuaries [PDF]

open access: yesNauplius, 2022
Carapace width-carapace length (CW/CLRs), carapace width-weight (CW/WRs), and carapace length-weight (CL/WR) relationships are presented for the portunid species Callinectes bocourti A.
