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)).

Morphology and function of the copulatory system in freshwater crabs of the genusPotamon

Journal of Morphology, 1999
To understand the reproductive processes of freshwater crabs of the genus Potamon, we examined the first and second gonopod and the gonoducts of the female by histological methods. The gonopods are highly modified compared to those of other brachyuran crabs.

Selection of gastropod prey by a tropical freshwater crab

Journal of Zoology, 1990
Prey selection by Somaniathelphusa sinensis (Parathelphusidae) among five gastropod species (two prosobranchs, three pulmonates) was associated with two snail attributes. First, the degree of defence of the tissues by the shell, approximated by shell weight (SW)/tissue dry weight (M).
