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 ...
Soldiers initiate foraging activities in the subterranean termite, Heterotermes tenuis
(Univ Arizona, 2008-01-09)
Caste polyethism has been recorded in some termite species, however the foraging behavior of subterranean termites remains poorly known. Heterotermes tenuis Hagen (Isoptera: Rhinotermitidae) is a subterranean termite that ...
Forage yield and quality in elephant grass cv. Pioneiro harvested at different cutting height sand times
This study aimed to evaluate the effect of cutting height and harvest time on forage yield and quality in elephant grass (Pennisetum purpureum Schum.) cv. Pioneiro. Experimental plots were arranged in a randomized block ...
Forager abundance and its relationship with colony activity level in three species of South American Pogonomyrmex harvester ants
The proportion of foragers in ant colonies is a fairly constant species-specific characteristic that could be determined by intrinsic or extrinsic factors. If intrinsic factors are relevant, species with similar life history ...
In vitro evaluation of various energy supplements for tropical and temperate forages.
(Amer Soc Animal Science, 2006-01-01)
Increase in scout trips due to forager removal in Atta sexdens (Hymenoptera, Formicidae) (Forel, 1908)
Social information exchange through physical contacts and chemical trail deposition forms the basis of food recruitment in leaf-cutting ants. The scout initiates the process and passes the information to nestmates that ...
Double purpose wheat: correlation analysis of forage yield components
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2010)
Assessment of predation risk via illumination level: facultative central place foraging in the cricetid rodent Phyllotis darwini
It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess ...
Iodine concentration in forages from dairy farms in the IXth and X-th Regions of Chile
(UNIV AUSTRAL CHILE. FAC CIENCIAS VETERINARIAS, 2003)
