The oldest freshwater crabs: claws on dinosaur bones. [PDF]

Sci Rep, 2019
Abstract With approximately 1,500 extant species, freshwater crabs (Decapoda: Brachyura) are among the most diverse decapod crustaceans. Nevertheless, their fossil record is extremely limited: only Potamidae, Potamonautidae and Trichodactylidae are reported up to the Eocene of the Neotropics so far.

Absorption of Silver on the Gills of a Freshwater Crab [PDF]

Nature, 1952
UNDER this title, Dr. D. W. Ewer and Ivan Hattingh1 quote in the following context a passage from a paper of mine2: “The localization of the silver-absorbing areas to certain gills which we have found in Potamon provides an exception to Koch's statement that ‘tous les organes decrits comme branchies chez les Crustaces…absorbent l'Ag'’.” However, the ...

Climate and Land-Use Change May Reshape the Biogeography of Freshwater Crabs Across China. [PDF]

Ecol Evol
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict

Sexual Disruption in the Freshwater Crab (Geothelphusa dehaani) [PDF]

Integrative and Comparative Biology, 2005
To clarify the effect of environmental endocrine disruptors on the induction of secondary sexual characteristics in wild animals, we observed 1,527 male and 1,847 female specimens of sexually mature Japanese freshwater crabs, Geothelphusa dehaani, collected at 12 sample points from 10 rivers in Sasebo City, Nagasaki Prefecture, Japan.

Catching crabs: a case study in local-scale English conservation [PDF]

, 2014
Wells-next-the-Sea and Cromer in Norfolk (England) both rely upon their local crab populations, since crabbing (gillying) is a major part of their tourist industry.

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin [PDF]

, 2014
Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments.

Incidence of Paragonimus Metacercariae in Freshwater Crabs in Ammapettai Village: A Pilot Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Paragonimus westermani is a significant lung fluke parasite that affects humans by causing a disease called paragonimiasis, transmitted through the consumption of inadequately cooked or pickled freshwater crabs (the second intermediate host)

Biased research generates large gaps on invertebrate biota knowledge in Brazilian freshwater ecosystems

Perspectives in Ecology and Conservation, 2020
Research biases are common and constant issues in biological research, with major consequences for biodiversity conservation. Freshwaters represent one of the most threatened ecosystems worldwide, but knowledge of freshwater biota is unevenly distributed

Anthropogenic CO₂-mediated freshwater acidification limits survival, calcification, metabolism, and behaviour in stress-tolerant freshwater crustaceans [PDF]

Biogeosciences, 2021
Dissolution of anthropogenic CO2 is chronically acidifying aquatic ecosystems. Studies indicate that ocean acidification will cause marine life, especially calcifying species, to suffer at the organism and ecosystem levels.
