Foraging behaviour of birds in an arid sand-dune scrubland in Argentina
(Csiro Publishing, 2005-12)
Studies of the foraging behaviour of birds allow exploration of the mechanisms that structure species assemblages. The major objective of this study was to describe relationships among various components of foraging behaviour ...
Foraging strategies and foraging plasticity in harvester ants (Pogonomyrmex spp., Hymenoptera: Formicidae) of the central Monte desert, Argentina
(Oesterreichische Gesell Entomofaunistik, 2015-09)
Foraging strategy determines the way harvester ants use space and therefore their access and impact on seed resources. In this study, we described the foraging strategy of three sympatric South American species of Pogonomyrmex ...
Behavioral suites mediate group-level foraging dynamics in communities of tropical stingless bees
(BIRKHAUSER VERLAG AG, 2010)
Competition for floral resources is a key force shaping pollinator communities, particularly among social bees. The ability of social bees to recruit nestmates for group foraging is hypothesized to be a major factor in ...
Effects of the association between Mimus saturninus and Furnarius rufus on their foraging and alert behaviors
(2022-01-01)
Several studies on the social behavior of birds have shown two main benefits of social groups: optimization of foraging and decreasing the risk of predation. We tested whether the association between rufous hornero (Furnarius ...
Foraging behavior of tyrant flycatchers (Aves, Tyrannidae) in Brazil
(Soc Brasileira Zoologia, Univ Federal Parana, 2005-12-01)
In this paper we present data on the foraging maneuvers and substrates used to capture preys by 28 species of tyrant flycatchers (Tyrannidae) in Brazil. For six species: Arundinicola leucocephala Linnaeus, 1764, Fluvicola ...
Group foraging in the colonial spider Parawixia bistriata (Araneidae): effect of resource levels and prey size
(Academic Press Ltd - Elsevier Science Ltd, 2007-11)
In animal groups whose focus is on juvenile growth, prey attributes and the way in which individuals have access to those prey influence the level of sociality. Models examining the evolution of group foraging predict that, ...
Numbers matter: predatory ability increases with forager group size in omnivorous ant species with similar predatory traits
Dataset used to carry out the analyses in the article "The more the better? Association between forager number and predation ability in omnivore ant species"
Article Abstract:
Predation is an important force structuring ...
Vigilance and collective detection of predators in degus (Octodon degus)
(BLACKWELL, 2006-09)
Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
Foraging by the omnivorous crab Pachygrapsus transversus affects the structure of assemblages on sub-tropical rocky shores
(Inter-research, 2010-01-01)
The roles of herbivory and predation in determining the structure and diversity of communities have been tested across most intertidal systems. In contrast, the importance of omnivorous consumers remains untested in many ...
