(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 ...
-
(OXFORD UNIV PRESS, 2006-09)center dot Background and Aims Broad surveys have detected inverse relationships between seed and adult longevity and between seed size and adult longevity. However, low and unpredictable precipitation is also associated ...
-
(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 ...
-
(SPRINGER, 2006-09)Pristine wilderness is a scarce global resource, but exotic species are so common that they constitute a principal component of worldwide ecological change. The relationship between these two topics, invasion and remoteness, ...
-
(BIRKHAUSER VERLAG AG, 2006-09)The plant apparency hypothesis predicts that apparent plants invest in broadly effective defences such as tannins while unapparent plants invest in specific toxins such as alkaloids. The stress hypothesis states that plants ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-09)Unfavorable temperatures and weather conditions for biotic pollination in above-tree-line alpine habitats predict self-compatibility, high levels of autogamy and small flower size ("autogamy reproductive assurance hypothesis"), ...
-
(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 ...
-
(BLACKWELL, 2006-11)Comparative and integrative tools are of fundamental value in ecology for understanding outcomes of biological processes, and making generalizations and predictions. Although ecosystem engineering has been shown to play a ...
-
(INST ARCTIC ALPINE RES, 2006-11)Low temperatures, short growing seasons, and strong winds, which constrain the abundance and activity of insect pollinators, characterize alpine ecosystems. In northern hemisphere alpine environments, the reproductive ...

(BLACKWELL, 2006-12)While climatic extremes are predicted to increase with global warming, we know little about the effect of climatic variability on biome distribution. Here, we show that rainy El Nino Southern Oscillation (ENSO) events can ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-12)Penalized likelihood analysis of previously published chloroplast DNA (cpDNA) ndhF sequences suggests that the central-southern Andean genus Chaetanthera diverged ca. 16.5 million years (my) ago, well before the uplift of ...
-
(SPRINGER, 2006-12)The red alga Mazzaella laminarioides is an economically important species with an extended latitudinal distribution along the Chilean coast. Its populations form mid-intertidal stands, several meters wide, and therefore ...
-
(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 ...

-
(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 ...
-
(2007)Rape] reservoir is an eutrophic system in Chile that has undergone a series of anthropogenic impacts in recent decades. To provide a better understanding of the processes occurring in the reservoir, we examined bacterial ...

(2007)Holocene fire-climate-vegetation linkages are mostly understood at individual sites by comparing charcoal and pollen records with other paleoenvironmental proxy and model simulations. This scale of reconstruction often ...
