-
(Elsevier, 2012)Much of the ongoing discussion regarding synchrony or bipolar asynchrony of paleoclimate events has centered on the timing and structure of the last glacial termination in the southern mid- latitudes, in particular the ...
-
(2014)We carried out an investigation and analysis of the relationships between the electronic structure and the metabotropic glutamate receptor subtype 5 affinity for a series of 2-amino- and 2-halothiazole derivatives using ...
-
(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 ...
-
(2014)We present an analysis of the relationships between the electronic structure and the SARS coronavirus papain-like protease inhibitory capacity of a series of 4-piperidinecarboxamide derivatives. The electronic structure ...
-
(ELSEVIER, 2005-02-11)Two hypotheses have attempted to explain the development of Mixed Paleofloras during the Cenozoic in South America. One of them postulates changes in the climatic tolerances of its component taxa and the other calls for ...
-
(Public Library Science, 2015)An understanding of biofilm formation is relevant to the design of biological strategies to improve the efficiency of the bioleaching process and to prevent environmental damages caused by acid mine/rock drainage. For this ...

(NATURE PUBLISHING GROUP, 2006-07-20)
-
(BLACKWELL, 2005-04)Species richness and taxonomic composition of pollinator assemblages are documented for 26 plant species from temperate rain forests of northern Chiloe Island, southern Chile (42 degrees 30'S). We investigated the patterns ...
-
(BLACKWELL, 2006-07)A humped-back relationship between species richness and community biomass has frequently been observed in plant communities, at both local and regional scales, although often improperly called a productivity-diversity ...
-
(SPRINGER, 2006-01)Carbon-based secondary compounds (CBSCs), such as phenols or tannins, have been considered as one of the most important and general chemical barriers of woody plants against a diverse array of herbivores. Herbivory has ...
-
(Blackwell, 2007)Aim Taxonomic comparisons of alien floras across climatically similar regions have been proposed as a powerful approach for increasing our understanding of plant invasions across scales. However, detailed comparisons between ...
-
(Springer, 2015)Forestry plantations supporting native species exhibit a dense understory, which might reduce bat activity within plantations. We compared bat activity in Monterrey pine plantations with and without an understory in ...
-
(Springer, 2012)Intraspecific variation in sociality is thought to reflect a trade-off between current fitness benefits and costs that emerge from individuals' decision to join or leave groups. Since those benefits and costs may be ...
-
(BLACKWELL, 2006-02)Aim To integrate the effects of ecosystem engineers (organisms that create, maintain or destroy habitat for other species) sharing the same archetype on species diversity, and assess whether different engineer species have ...
-
(BLACKWELL, 2007-07)1. Ecosystem engineers are organisms that change abiotic conditions in ways that affect the performance and distribution of other species, including exotics. Several mechanisms have been proposed for the successful ...
-
(ELSEVIER, 2006-03-01)Forest edges have been long recognized as the first landscape elements to be invaded by alien plant species in forest ecosystems. However, little is known about the role of forest edge type in invasive species patterns. ...
-
(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 ...
-
EFFECT OF DENSITY AND FLOWER SIZE ON THE REPRODUCTIVE SUCCESS OF NOTHOSCORDUM GRAMINUM (ALLIACEAE) (2006)The size, form and color are signals used by flowers to attract their pollinators. Large and showy color flowers usually receive higher pollinators visitation rates. According to the optimal forage theory, pollinators would ...
-
(Springer, 2016)For polyandrous species where females have sperm storage structures, males develop several strategies to avoid sperm competition and thus to maximize the number of eggs fertilized. On the other hand, females may receive ...
-
(ELSEVIER, 2006-04)North American beavers (Castor canadensis) were introduced into southern South America in 1946. Since that time, their populations have greatly expanded. In their native range, beavers shape riparian ecosystems by selectively ...
