(ECOLOGICAL SOC AMER, 2011-02)The abundance of exotic plants is thought to be limited by competition with resident species (including plants and generalist herbivores). In contrast, observations in semiarid Chile suggest that a native generalist rodent, ...
-
(GEOLOGICAL SOC AMER, 2011-05)Terrestrial records from 41 to 52 degrees S across the Southern Hemisphere reveal nearly synchronous multimillennial trends in moisture derived from the Southern Westerly Winds (SWW) since 14 ka, pointing to a marked zonal ...
-
(SPRINGER, 2010-10)To describe comparative population genetic structure of the Chilean silverside Basilichthys microlepidotus and the catfish Trichomycterus areolatus, four rivers and three sites within each river were investigated by ...
-
(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 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 ...
-
(2010-04-06)The aim of this study was to investigate, during the summer of the year 2008, the variation in leaf water and photosynthetic characteristics of Eucryphia cordifolia Cav. (Cunoniaceae) along its broad latitudinal ...
-
Predicting effects of ecosystem engineering on species richness along primary productivity gradients (ELSEVIER, 2010)Physical ecosystem engineering is the process by which some species change the distribution of materials and energy in ecosystems. Although several studies have shown that this process is a driver of local species ...
-
(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 ...
-
(2010)The effect of colonization on the distribution of genetic diversity within and among populations in relation to species characteristics remains an open empirical question. The objective of this study was to contrast genetic ...
-
(Springer, 2010)Larval identiWcation represents a powerful tool for detailed studies on recruitment and population dynamics in marine invertebrates. However, intra-speciWc morphological variation can become a serious limitation for ...
-
Changing fire regimes in the temperate rainforest region of southern Chile over the last 16,000 yr (ELSEVIER, 2008)A high-resolution macroscopic charcoal record from Lago Melli (42°46′S, 73°33′W) documents the occurrence of forest fires in the lowlands of Isla Grande de Chiloé, southern Chile, over the last 16,000 yr. Our data suggest ...
-
(Oceanological Research Institute of UABC, 2008)A regular seasonal pattern of periodicity was detected in monthly catch data for Dosidicus gigas during the most recent period of high abundance of the species off Chile. Monthly catch data covering from 2002 to 2005 were ...
-
(UNIV CHICAGO PRESS, 2008-04)The endemic southern South American genus Hamadryas (Ranunculaceae), consisting of five species, has been regarded as closely related to or part of Ranunculus s.l. (tribe Ranunculeae) based on morphological observations. ...
-
(SPRINGER, 2008-04)We assessed differences in the development rates among anchoveta, E. ringens populations from the extremes of its range under different temperatures. Time to hatch decreased with increasing temperature but there was no ...
-
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 ...
-
(Springer Berlin, 2008-06)Fire activity has varied globally and continuously since the last glacial maximum (LGM) in response to long-term changes in global climate and shorter-term regional changes in climate, vegetation, and human land use. ...
-
(Sociedad de Biología de Chile, 2008-06)El flujo de entrada de nitrógeno (N) en ecosistemas de bosques templados de la Isla de Chiloé puede ocurrir en una proporción importante vía fijación no simbiótica (FNS). Debido a que este proceso es llevado a cabo por ...
-
(SPRINGER, 2008-04)Invasive species can increase fire frequency and intensity, generating favorable conditions for their self-perpetuation. Mediterranean south-central Chile may be especially prone to the effects of invasive species on fire ...
-
(Socieda de Biología de Chile, 2008-12)Las turberas son ecosistemas reconocidos mundialmente por actuar como grandes reservorios de agua dulce, afectando el clima y la hidrología local; por ser sumideros de carbono; por albergar especies únicas, contribuyendo ...
