Metabolic responses of pleustonic and burrowing freshwater crabs exposed to endosulfan
(Parlar Scientific Publications, 2012-06)
This work focused on the effects on metabolism of environmental concentrations of endosulfan in the freshwater crabs Dilocarcinus pagei and Zilchiopsis collastinensis. The concentrations used were 0, 6 and 62 μg of endosulfan ...
Range extension for three species of South American freshwater crabs (Crustacea: Decapoda: Trichodactylidae)
(Magnolia Press, 2009-03)
New sampling programs have extended the distribution of three species of freshwater crabs (family Trichodactylidae): Dilocarcinus septemdentatus and Sylviocarcinus pictus from the Amazon basin to southern South America, ...
Predation ability of freshwater crabs: age and prey-specific differences in Trichodactylus borellianus (Brachyura: Trichodactylidae)
(Taylor & Francis, 2013-06)
Freshwater crabs are rarely represented in food webs and their role in these ecosystems has been largely ignored. Trichodactylus borellianus is an omnivorous crab species that has a diverse natural trophic spectrum. This ...

Offspring production in three freshwater crab species (Brachyura: Pseudothelphusidae) from the Amazon region and Central America
(Sociedade Brasileira de Zoologia, 2010)
Freshwater crabs are an important component of the fauna of limnic environments, and out of the two true freshwater crab families present in the Neotropics, Pseudothelphusidae is the most diverse. Considering the lack of ...
Neotropical freshwater crabs (Decapoda: Pseudothelphusidae) shred leaves
(2020)
Freshwater crabs are macroconsumers that are commonly found in Neotropical headwater streams that may play a key role in energy flow and nutrient cycling in detrital food webs. Although studies have examined the feeding ...
ATP pulse and calcium homeostasis in cells from hepatopancreas of Dilocarcinus pagei, a freshwater crab
(ELSEVIER SCIENCE INC, 2011)
Calcium (Ca) is critical for crustaceans due to their molting cycle and its presence in the carapace as calcium carbonate, apart from the usual functions of Ca, such as cell signalling. Ca transport in Dilocarcinus pagei, ...
The diel feeding rhythm of the freshwater crab Trichodactylus borellianus (Decapoda: Brachyura) in mesocosm and natural conditions
(Taylor & Francis, 2013-05-28)
Biorhythm studies have rarely used feeding rhythms of freshwater crustaceans to assess the internal clock. Even less often, they have compared the diel rhythms of juveniles and adults. In this study, the 24-h cyclic feeding ...
