Última Ecological partitioning of three Columbidae species in Northern Paraná, Southern Brazil Biota Neotropica Fontoura,Priscila Montes; Orsi,Mário Luis. Three species of Columbidae (Columbina talpacoti,Columbina picui and Zenaida auriculata) were studied in Londrina, Northern Paraná (Brazil), with the aim of analyzing which foraging and habitat factors contribute to their ecological partitioning. The study was conducted over one year in three different areas (urban, rural and pasture). We made monthly observations of the foraging strategies used by the species and the habitats they selected. Possible variations in availability of resources over the twelve months of the study did not influence the type of foraging used by the three species. Significant differences between the foraging strategies used by the species were observed in relation to the foraging site, specifically the foraging substrate. Soil,...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032013000300044 Trophic ecology and foraging behavior of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata, Tropiduridae) in a caatinga area of northeastern Brazil Iheringia, Sér. Zool. Ribeiro,Leonardo B.; Freire,Eliza M. X.. This study aimed to analyze the seasonal variation in diet composition and foraging behavior of Tropidurus hispidus (Spix, 1825) and T. semitaeniatus (Spix, 1825), as well as measurement of the foraging intensity (number of moves, time spent stationary, distance traveled and number of attacks on prey items) in a caatinga patch on the state of Rio Grande do Norte, Brazil. Hymenoptera/Formicidae and Isoptera predominated in the diet of both species during the dry season. Opportunistic predation on lepidopteran larvae, coleopteran larvae and adults, and orthopteran nymphs and adults occurred in the wet season; however, hymenopterans/Formicidae were the most important prey items. The number of food items was similar between lizard species in both seasons;... Tipo: Info:eu-repo/semantics/article Palavras-chave: Diet; Foraging strategies; Lizards; Semiarid; Sympatric species. Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0073-47212011000200010 Unravelling the foraging behavior of the southern stingray, Hypanus americanus (Myliobatiformes: Dasyatidae) in a Southwestern Atlantic MPA Neotropical Ichthyology Freitas,Renato H. A.; Aguiar,Aline A.; Freitas,Ana Karina C. H. A.; Lima,Sergio M. Q.; Valentin,Jean L.. ABSTRACT Previous study suggested that the southern stingray (Hypanus americanus) displays a marked ontogenetic shift in its habitat use in the Fernando de Noronha Archipelago (FNA), an attractive touristic spot in Brazil, that could be associated with changes in its feeding habits and foraging strategies. Here, we conducted underwater visual surveys (~100 h a 3 years’ study) at this site to describe the foraging behavior of the same species in details and to assess diel patterns in activity. We observed that H. americanus is capable of several complex and highly plastic behaviors (we described more than 21 of them) while foraging. The foraging events’ timing appears to be related to the size (as well as sex) of the stingrays, environment and depth. In...

Osorio-Beristain,Marcela; Rodríguez,Ángeles; Martínez-Garza,Cristina; Alcalá,Raúl Ernesto. ABSTRACT Flight initiation distance (FID), defined as the distance at which an individual flees from an approaching predator, might depend on how the individual perceives the risk of being predated. Using a standardized walking approach method on focal bird individuals, we investigated whether different levels of vegetation cover (habitat) influence the perception of predation risk. To do this, we worked in an area of tropical dry forest in central Mexico that is currently part of a restoration ecology experiment. We hypothesized that restoration decreases individual’s predation risk perception by increasing the complexity of the vegetation cover. The escape responses of three tropical birds with different diets and foraging strategies were also...
