(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 ...
-
(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. ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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. ...
-
(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)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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(SPRINGER, 2006-07)The decrease in temperature with increasing elevation may determine the altitudinal tree distribution in different ways: affecting survival through freezing temperatures, by a negative carbon balance produced by lower ...
-
(ELSEVIER, 2006-07)Simple patch-occupancy models of competitive metacommunities have shown that coexistence is possible as long as there is a competition-colonization tradeoff such as that of superior competitors and dispersers. In this ...
-
(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 ...
-
(BLACKWELL, 2006-07)Ecosystem engineers are organisms able to modulate environmental forces and, hence, may change the habitat conditions for other species. In so doing, ecosystem engineers may affect both species richness and evenness of ...

(NATURE PUBLISHING GROUP, 2006-07-20)
-
(BLACKWELL, 2006-08)The foraging ecology of hummingbirds involves the exploitation of a high number of patchily distributed flowers. This scenario seems to have influenced capabilities related to learning and memory, which help to avoid ...
