(BRITISH HERPETOL SOC, 2006-01)Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...
-
(NATL ACAD SCIENCES, 2006-01-10)Species invasions are a principal component of global change, causing large losses in biodiversity as well as economic damage. Invasion theory attempts to understand and predict invasion success and patterns of spread. ...
-
(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, 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, 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) ...
-
(BLACKWELL, 2006-02)Aim We ask whether contemporary forests of the Chilean Coastal Range can be considered to be direct and conservative descendants of pre-Pleistocene palaeofloras that occurred in southern South America from the Palaeogene ...
-
(SOCIEDAD BIOLGIA CHILE, 2006-03)Photosynthesis of Colobanthus quitensis and mesoclimatic conditions of air temperature and light intensity during the growing season were investigated at 2,650 in ill the central Chilean Andes. Oil three typical days of ...
-
(ECOLOGICAL SOC AMER, 2006-03)Climatic changes associated with the El Nino Southern Oscillation (ENSO) can have a dramatic impact on terrestrial ecosystems worldwide, but especially on arid and semiarid systems, where productivity is strongly limited ...
-
(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. ...
-
(SPRINGER, 2006-04)
-
(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 ...
-
(SPRINGER, 2006-04)Non-native (alien, exotic) plant invasions are affecting ecological processes and threatening biodiversity worldwide. Patterns of plant invasions, and the ecological processes which generate these patterns, vary across ...
-
(INST ARCTIC ALPINE RES, UNIV COLORADO, 2006-05)High mountain environments are highly stressful for insect survival. It has been suggested that small microtopographic variations generating less stressful microclimatic conditions than the surrounding environment would ...
-
(BLACKWELL, 2006-05)Understanding how animals interact with their environment is critical for evaluating, mitigating and coping with anthropogenic alteration of Earth's biosphere. Researchers have attempted to understand some aspects of these ...
-
(SPRINGER, 2006-06)Tree presence in semiarid ecosystems is generally constrained by insufficient annual rainfall. However, in semiarid Chile, rainforest patches dominated by Aextoxicon punctatum are unexpectedly found on coastal mountaintops ...
-
(RESILIENCE ALLIANCE, ACADIA UNIV, BIOLOGY DEPT, 2006-06)Although there is general agreement among conservation practitioners about the need for ( 1) social involvement on the part of scientists; ( 2) interdisciplinary approaches; ( 3) working on local, regional, and global ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-06)In recent years natural history has been derided by some scientists as an old-fashion endeavor that does not follow the model of "hard" science and therefore should be considered "dead" and replaced by modern ecology, ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-06)There is an exceptional group of alpine peatlands in the world situated in the and grasslands of the central Andes. The peatlands in northern Chile occur in the most arid part of their range. Members of the Juncaceae are ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-06)Plant breeding systems are considered to reflect species' life history characteristics, selection due to biotic or abiotic factors, pollination conditions, or a combination of these. Reproductive systems may vary over ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2006-06)We assessed the geographic distribution of Tillandsia lomas in northern Chile, from Arica (18 degrees 20'S) to the Loa river (21 degrees 25'S) and discussed the factors that might potentially underlie the observed patterns. ...
