Effects of nest-site characteristics and parental activity on cowbird parasitism and nest predation in Brown-and-yellow MarshbirdsEfectos de las características del sitio de nidificación y actividad parental en el parasitismo de cría por tordos y predación de nidos en Pseudoleistes virescens
(Wiley Blackwell Publishing, Inc, 2009-03)
Nest-site selection and nest defense are strategies for reducing the costs of brood parasitism and nest predation, two selective forces that can influence avian nesting success and fitness. During 2001-2002, we analyzed ...
Building multiple nests is associated with reduced breeding performance in a south temperate population of Grass Wrens Cistothorus platensis platensis
(Wiley Blackwell Publishing, Inc, 2020-01)
Grass Wrens Cistothorus platensis build two types of non-breeding nest structures: platforms and dummy nests. Platforms are rudimentary accumulations of grasses concealed between vegetation. Dummy and breeding nests are ...
Internal architecture and population size of Acromyrmex subterraneus molestans (Hymenoptera, Formicidae) nests: Comparison between a rural and an urban area
(2011-11-30)
Ant nests vary in their depth and internal complexity. They can be shallow or reach seven meters down into the soil, with many chambers connected by tunnels. In the case of leaf-cutting ants, the nest protects the colony ...
Dense canopy cover over House Wren (Troglodytes aedon) nests increases latency of brood parasitism by Shiny Cowbirds (Molothrus bonariensis)
(Csiro Publishing, 2012-02)
Obligate brood parasites must find host nests in which to lay their eggs. The search for a suitable host nest is predicted to be more difficult if the host nest is well-concealed by vegetation (nest-concealment hypothesis) ...
Energy substrate used by workers of leaf-cutting ants during nest excavation
(Sociedade Brasileira de Entomologia, 2013-12-01)
Energy substrate used by workers of leaf-cutting ants during nest excavation. In this study we aimed to ascertain whether leaf-cutting ant workers lose body reserves (fat or sugars) as a function of nest excavation. For ...

(Springer Tokyo, 2017-03)
Clearing of caldén (Prosopis caldenia) forests for agriculture and cattle raising in east-central La Pampa Province, central Argentina, has created a highly fragmented landscape, a condition that has resulted in adverse ...
