Research Article: Feed comparison and feeding ecology in five sympatric teleost species of the northern Oman Sea
Investigating the relations and mechanisms of coexistence among sympatric species is essential to comprehend their ecological roles in the food webs. In the present study, the diet and trophic interactions of 5 abundant teleost species coexisting in the northern Oman Sea were examined using stomach contents analyses. The cumulative prey curves showed that the sample size of each studied species...
متن کاملComparative feeding ecology of four syntopic Hypostomus species in a Brazilian southeastern river.
Though their broad distribution in most Brazilian rivers, scarce studies concerning ecological interactions on Hypostomus species are available. This study observes the diet, the trophic interactions and some morphological aspects of four syntopic species of Hypostomus. These fishes were studied at the superior part of the Corumbataí river, at São Paulo state, southeastern Brazil. Analyses focu...
متن کاملThe Feeding Ecology of Aneides flavipunctatus and Sympatric Plethodontid Salamanders in Northwestern California
-Seasonal and ontogenetic variation in the diets of Aneides flavipunctatus and three sympatric plethodontids (A. lugubris, Batrachoseps attenatus, and Ensatina eschscholtzii) were studied at three localities in northwestern California. A wide variety of prey was eaten by the four species, but 75-95% of the total food volume at any one season and location was contributed by Diplopoda, Coleoptera...
متن کاملCompetition and feeding ecology in two sympatric Xenopus species (Anura: Pipidae)
The widespread African clawed frog (Xenopus laevis) occurs in sympatry with the IUCN Endangered Cape platanna (Xenopus gilli) throughout its entire range in the south-western Cape, South Africa. In order to investigate aspects of the interspecific competition between populations of X. laevis and X. gilli, an assessment of their niche differentiation was conducted through a comprehensive study o...
متن کاملFeeding Ecology of the California Mountain Kingsnake, Lampropeltis zonata (Colubridae)
Based on stomach contents of museum specimens and published records (n 5 51 prey items), Lampropeltis zonata eats lizards (37, 72.5%), squamate eggs (6, 11.8%), mammals (6), and birds (2, 3.9%). Juveniles feed on lizards, especially Sceloporus (spiny lizards) and Eumeces (skinks), whereas adults supplement their diet with squamate eggs and endothermic prey. Prey items are located by active fora...
