Food Resource Partitioning

The current work investigates dietary overlap and food partitioning among nine abundant carnivorous fishes caught in the shallow waters of the Paraíba do Norte river estuary, Paraíba State, Brazil. Fishes were sampled with a beach seine net between January and December 2008 and a total of 958 specimens had their stomach content analyzed. Crustacea was the dominant food resource for Lutjanus alexandrei, L. jocu and Bathygobius soporator, whereas Telostei were consumed mainly by Centropomus undecimalis and C. parallelus. In contrast, Polychaeta were preyed upon mainly by Diapterus rhombeus, Eucinostomus argenteus, Sciades herzbergii and S. parkeri. Although most species consumed similar food items, they did that in varying proportions and amounts. Overall, the niche overlap among species was low (< 0.60), but there were several cases where pair of species had their feeding niche highly overlapped (between 0.72 and 0.97). These findings corroborate the hypothesis that food resource partitioning determines species coexistence in estuarine tropical environments.

Food Resource Partitioning

The dietary compositions of two sit-and-wait lizard species, Hemidactylus mabouia and Phyllopezus pollicaris, which co-occur over rocky substrate and vertical rock walls in a perianthropic area of western Brazil, were described. Both species showed a generalist feeding pattern, feeding mainly on insects. The most frequent prey items in the diet of P. pollicaris were Coleoptera, Araneae and Homoptera whereas the most important were Coleoptera and Homoptera, respectively. For H. mabouia the most frequent prey items were Araneae followed by Coleopterae and Hemiptera, whereas the most important items were H. mabouia followed by Formicidae and Hemiptera. Our identification into broader prey-types categories (i.e., order or family-level) suggests that some degree of food resource partitioning may occur, possibly through the occupation of different temporal niches.
