(SOCIEDAD BIOLOGIA CHILE, 2007-03)Successional shrublands created by clearcutting and burning of forests are frequent in Chiloe Island and surrounding mainland in southern Chile. These areas are characterized by seasonally waterlogged soils, and vegetation ...
-
(American Physical Society, 2015)The localized mode propagation in binary nonlinear kagome ribbons is investigated with the premise to ensure controlled light propagation through photonic lattice media. Particularity of the linear system characterized by ...
-
(2013)Although barotropic matter does not constitute a realistic model for magnetic stars, it would be interesting to con rm a recent conjecture that states that magnetized stars with a barotropic equation of state would ...
-
Male and female golden whistlers respond differently to static and dynamic signals of male intruders (OXFORD UNIV PRESS INC, 2008-09)Bird displays vary widely in their sensitivity to changes in signaler condition. Plumage ornaments are generally static and undergo minimal change. Behavioral ornaments, by contrast, are dynamic and may track signaler ...
-
(SPRINGER, 2008-06)Male paternity assurance behaviour during the female fertile period has been widely documented amongst birds. In contrast, how sex-specific behavioural strategies vary with local breeding synchrony levels remains ...
-
(BLACKWELL, 2006-02)We studied the effects of fragment size, vegetation structure and presence of habitat corridors on the reproductive success of the Des Murs' Wiretail (Sylviorthorhynchus desmursii Des Murs, Furnariidae), a small (10 g) ...
-
(INST ARCTIC ALPINE RES, UNIV COLORADO, 2007-05)Cushion plants are one of the most common growth forms in alpine habitats. Their low stature, dense canopy, and compact form allow them to decouple their microclimate from the surrounding environment, mitigating the effect ...
-
(Cambridge University Press, 2010)Intraerythrocytic parasites (Apicomplexa: Sarcocystidae) of the South American mouse opossum (Thylamys elegans) from Chile, South America, and of the yellow-bellied glider (Petaurus australis) from Australia were found ...
-
(2007)The present study describes new records for the buccinid gastropods Aeneator fontainei (D'Orbigny, 1841) and Aeneator loisae Redher, 1971 collected in Chile's southern fjord region in 2001 and 2002. This report now extends ...
-
(OXFORD UNIV PRESS, 2006-07)Background and Aims Post-dispersal seed predation in alpine communities has received little attention despite evidence that seeds removed by granivores can decrease plant recruitment into ecosystems. Moreover, few studies ...
-
(ELSEVIER, 2006-01)Urbanization is increasingly homogenizing the biota of less developed countries. Even though urban sprawl is a worldwide problem, most studies on the effects of urbanization, and the conceptual models have focused on ...
-
(AMER METEOROLOGICAL SOC, 2006-08)Results are reported from two 5-month-long simulations for southern South America using the fifth-generation Pennsylvania State University - NCAR Mesoscale Model (MM5). The periods of simulation correspond to May - September ...
-
(Wilson Ornithological Soc, 2016)We present descriptions of nest architecture, clutch size, nestling growth and nestling attendance for the Fire-eyed Diucon (Xolmis pyrope), based on nests found at the Fray Jorge National Park, Chile, at the northernmost ...
-
(BMC, 2021)Background The connection between testosterone and territoriality in free-living songbirds has been well studied in a reproductive context, but less so outside the breeding season. To assess the effects of seasonal androgenic ...
-
(John Wiley, 2016)Along the south-western coast of South America, three genera of fossil phocids (true seals) have been formally described from the late Neogene: Acrophoca and Piscophoca from Chile and Peru, and, more recently, Hadrokirus ...
-
(Ecological Society of Australia, 2010)Heterotrophic nitrogen fixation is a key ecosystem process in unpolluted, temperate old-growth forests of southern South America as a source of new nitrogen to ecosystems. Decomposing leaf litter is an energy-rich substrate ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-09)Nurse effects, which occur when one plant species enhances the survival or growth of another plant species, are predicted to be most relevant in stressful environments. These effects are particulary important during seedling ...
-
(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 ...
-
(UNIV CHICAGO PRESS, 2007-01)The effects of energy on food web structure have been debated for at least 80 years. Nevertheless, the empirical evidence is meager, especially from terrestrial ecosystems. We analyzed long-term temporal variation in food ...
-
(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 ...
