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 ...
Gut evacuation time of macrobrachium borellii (Caridea: Palaemonidae) feeding on three types of prey from the littoral-benthic community
(Crustacean Society, 2011-10)
Gut evacuation time is a very useful parameter that allows us to understand the daily trophic cycle of a predator. Macrobrachium borellii is an inhabitant of the littoral-benthic community of the Paran River system that ...
Natural Prey and Digestion Times of Toxorhynchites rutilus (Diptera: Culicidae) in Southern Florida
(Oxford University Press, 2000-11)
Natural prey of Toxorhynchites rutilus (Coquillett) were identified from gut contents of 941 larvae collected from treeholes and tires located in an oak-palm woodland in south Florida. Twenty taxa of aquatic prey were ...
Influence of prey size on predation success by Zelus longipes L. (Het, Reduviidae)
(Blackwell Verlag GmbhBerlinAlemanha, 2002)
Bacterial community associated with traps of the carnivorous plants Utricularia hydrocarpa and Genlisea filiformis
(Elsevier B.V., 2014-05-01)
The species of bacteria associated with the traps of the carnivorous plants Utricularia hydrocarpa Vahl and Genlisea filiformis A. St.-Hil. were identified by analysing 16S rRNA gene libraries. We observed larger bacterial ...
Age-related prey selectivity and foraging efficiency in Olrog's Gulls Larus atlanticus feeding on crabs in their non-breeding grounds.
(Csiro Publishing, 2011-05)
Foraging ecology is an essential component of the life history of a species and a good understanding of foraging ecology is especially important for threatened species where prey populations may be adversely affected by ...
Meal size effects on the postprandial metabolic response of Bothrops alternatus (Serpentes: Viperidae)
(2013-07-15)
We examined the effects of meal size on the postprandial metabolic response of the lancehead Bothrops alternatus (Duméril, Bibron & Duméril, 1894), fed mice equaling to 5, 10, 20, and 40% of the snake's body mass. The ...

We examined the effects of meal size on the postprandial metabolic response of the lancehead Bothrops alternatus (Duméril, Bibron & Duméril, 1894), fed mice equaling to 5, 10, 20, and 40% of the snake's body mass. The ...
Development and distribution of intestinal enzymatic activity in Paralabrax maculatofasciatus larvae fed live prey
(Aquaculture Research, 2009)
We describe the development and distribution of intestinal aminopeptidase M, dipeptidyl aminopeptidase IV, non-speci¢c esterase, alkaline phosphatase and acid phosphatase, using enzyme histochemistry techniques, in the ...
