Evolutionary History of True Crabs (Crustacea: Decapoda: Brachyura) and the Origin of Freshwater Crabs [PDF]

open access: yesMolecular Biology and Evolution, 2014
Crabs of the infra-order Brachyura are one of the most diverse groups of crustaceans with approximately 7,000 described species in 98 families, occurring in marine, freshwater, and terrestrial habitats. The relationships among the brachyuran families are poorly understood due to the high morphological complexity of the group.

Phylogenomic analyses of brachyuran crabs support early divergence of primary freshwater crabs

Molecular Phylogenetics and Evolution, 2019
Recent fossil calibrated molecular phylogenies have revealed that the Brachyura underwent rapid radiation during the Cretaceous and Early Tertiary, resulting in many early diverging lineages separated by short internodes that remain difficult to resolve.

The freshwater Grapsid crabs of Jamaica

Proceedings of the Linnean Society of London, 1964
SUMMARY. Four species of grapsid crabs, endemic to Jamaica, spend the whole of their life cycle in fresh water; an account of their biology is given. Metopulias depressus is confined to the water which collects at the base of large tank bromeliads, and is limited to limestone regions above an elevation of about a 1000 ft.

Sublethal effects of copper on the freshwater crab Potamonautes warreni

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002
The mass specific rates of oxygen consumption (M (O(2)) M(b)(-1)), ammonia excretion (M (NH(4)-N) M(b)(-1)) and carbon dioxide production (M (CO(2)) M(b)(-1)) were measured after 7, 14 and 21 days exposure of adult Potamonautes warreni to a sublethal concentration of 1.0 mg Cu l(-1) (15.75 micromol l(-1)).
