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 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 ...

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 ...

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 ...

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 ...

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 ...

Themisto gaudichaudii and Euphausia lucens are important prey of several fish and squid species of commercial value in the southwest Atlantic Ocean. Although allometric relationships linking size and weight can be used to ...
