Female body size, fecundity parameters and foundation of new colonies in Anelosimus jabaquara (Araneae, Theridiidae)
(Birkhauser Verlag AgBaselSuíça, 2001)
Conspecific food competition explains variability in colony size: a test in magellanic penguins
(Ecological Society of America, 2002-12)
Food availability has been proposed as one of the main factors regulating population sizes in birds. Seabirds have provided evidence for the hypothesis that food depletion due to intraspecific competition explains variability ...
Forager abundance and its relationship with colony activity level in three species of South American Pogonomyrmex harvester ants
(Springer, 2013-02)
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 ...
Natural History and Ecological Correlates of Fungus-Growing Ants (Formicidae: Attini) in the Neotropical Cerrado Savanna

Testing methods to estimate abundance of Magellanic Penguins Spheniscus magellanicus
(Taylor & Francis, 2014-07)
Capsule: Using simulations in a geographical information system our results showed that systematic sampling with quadrats was the most accurate, precise and cost-effective method to survey Magellanic Penguin colonies. ...
Influence of the colony cycle on physiological and morphological caste variation in the perennial neotropical swarm-founding social wasp, Protonectarina sylveirae (Hymenoptera, Vespidae, Epiponini)
(2003-08-18)
This paper describes the influence of the colony cycle on caste differences in Protonectarina sylveirae. Despite invariably keeping the main aspects of the conspicuous dimorphism between the castes, it is shown that: 1- ...

Growth patterns of incipient colonies of Coptotermes havilandi (Isoptera, Rhinotermitidae) initiated in the laboratory from swarming alates
(2001-12-01)
Fifty two colonies of Coptotermes havilandi were set up under laboratory conditions using alates collected from an urban area during a period of swarming. The first artificial nest used for each royal couple was a 6cm ...
