(BRILL ACADEMIC PUBLISHERS, 2006-07)Nest-mate recognition and territorial behaviour in ants are widely studied phenomena. However, few studies have analysed, under field conditions, how nest-mate recognition varies with distance from the resident's colony. ...
-
(Walter de Gruyter, 2016)We report a new locality for the rodent Chelemys megalonyx in Rinconada de Maipu (Santiago, metropolitan region, central Chile), located in the central valley of Chile, in the eastern slope of the Chilean coastal range. ...
-
(Oxford University Press, 2016-04)A growing body of evidence showing that individuals of some social species live in non-kin groups suggests kin selection is not required in all species for sociality to evolve. Here, we investigate 2 populations of Octodon ...
-
Olfactory conditioning in mate searching by the parasitoid Aphidius ervi (Hymenoptera: Braconidae) (Cambridge University Press, 2008)Despite the fact that insect learning capacity has been broadly demonstrated, the role that this process plays during mate searching has been scarcely explored. We studied whether the sexual behaviour of a male parasitic ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-09)It has been hypothesized that species belonging to the Sturnidae-Muscicapidae lineage, despite having generalist diets comprising fruits with sugars of diverse kinds, do not express intestinal sucrase. In order to increase ...
-
(BLACKWELL, 2006-02)Little is known about how animals acquire and use prior information, particularly for Bayesian patch assessment strategies. Because different patch assessment strategies rely upon distinct capabilities to obtain information, ...
-
(Blackwell, 2010)For sexual selection to operate in monogamous species, males of poor quality in some factor like age, ornamentation, condition or aggressiveness, should lose paternity compared with higher quality males. We tested this ...
-
(Elsevier, 2017)The properties of nanometric materials make nanotechnology a promising platform for tackling problems of contemporary medicine. In this work, gold nanorods were synthetized and stabilized with polyethylene glycols and ...
-
(SPRINGER, 2010-10)The male of Ixodes abrocomae Lahille, 1916 (Acari: Ixodidae) is redescribed and the female described for the first time from specimens collected on the rodents Abrothrix longipilis (Waterhouse), A. olivaceous (Waterhouse) ...
-
(CAMBRIDGE UNIV PRESS, 2009-06)Avian Plasmodium and Haemoproteus parasites are easily detected by DNA analyses of infected samples but only correctly assigned to each genus by sequencing and use of a phylogenetic approach. Here, we present a restriction ...
-
(WILEY-BLACKWELL PUBLISHING, INC,, 2008-11)The blood of 21 adult South American mouse opossums (Thylamys elegans) captured from April through August of 2005 in central Chile was examined for parasites. Light microscopic analysis of blood smears initially suggested ...

-
(2013)The roles of testosterone (T) during reproduction are often complex and vary among and within vertebrate taxa and locations, making general hypotheses relating T to breeding behavior and success difficult to integrate. In ...
-
(Elsevier, 2014)Across vertebrates, the hypothalamic–pituitary–adrenal axis is a conserved neuroendocrine network that responds to changing environments and involves the release of glucocorticoids into the blood. Few studies have been ...
-
(Universidad de Chile, 2009)La endogamia es considerada como un factor determinante en la selección de pareja y en el éxito reproductivo de animales silvestres. Sin embargo, los estudios que analizan la importancia de la selección de pareja y la ...
-
(Springer Verlag, 2017)In birds, the frequency with which the parents feed the young can vary considerably. Because of sexual differences in the begging behaviour and/or differences in the food requirements of the nestlings, brood sex ratio ...
-
(2007)Sexual dimorphism, mating system, and parental care are known for only a few species of the large passerine family Furnariidae. We conducted a study of sexual dimorphism in morphology, coloration, and parental roles ...
-
(Taylor & Francis, 2017)Territorial behaviour is an active and typically aggressive behaviour used to defend resources. Here, we investigated the presence of shared territorial defence behaviour during conspecific intrusions in the Thorn-tailed ...
-
(BLACKWELL, 2007-01)The spatial structure of habitats contains physical barriers that restrict the performance of diverse behavioural tasks. In heterogeneous habitats, information acquisition may allow animals to improve the performance of ...
-
(Academic Press, 2016)© 2015 Elsevier Ltd. The avifauna of Chile is relatively depauperate, comprising 469 extant species, of which 213 are terrestrial. However, the Coquimbo Region presents a broad ecological transition from the hyperarid ...
