-
(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 ...
-
(BLACKWELL, 2007-03)While it is a truism that species rarity is non-randomly distributed across regions, habitats, and taxa, there is little consensus on which factors are the best predictors of low abundances and restricted geographical ...
-
(Pensoft, 2021)This study provides the summary of the reports of the geographical distribution in the Maritime Antarctic and sub-Antarctic regions of Parochlus steinenii (Gercke, 1889) (Diptera, Chironomidae), the only flying insect ...
-
(Elsevier, 2015)Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms ...
-
(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) ...
-
(Oxford Univ Press, 2015)Landscape fragmentation is often a major cause of species extinction as it can affect a wide variety of ecological processes. The impact of fragmentation varies among species depending on many factors, including their ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007-01)Most semi-arid and and regions around the world have lost a major part of their original vegetation.. Restoration of once shrublands and woodlands is often challenged by low seedling establishment success due to water ...
-
(SPRINGER, 2007-07)El Nino Southern Oscillation (ENSO) events have profound consequences for the dynamics of terrestrial ecosystems. Since increased climate variability is expected to favour the invasive success of exotic species, we conducted ...
-
(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 ...
-
(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 ...
-
(Biomed Central, 2016)Background: Environmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage. Modification of telomere length, as a result of adversity faced early in life, can ...
-
(MDPI, 2022)Xanthophyllomyces dendrorhous is a natural source of astaxanthin and mycosporines. This yeast has been isolated from high and cold mountainous regions around the world, and the production of these secondary metabolites ...
-
(COMPANY OF BIOLOGISTS LTD, 2005-05)Scaling relationships (where body size features as the independent variable) and power-law distributions are commonly reported in ecological systems. In this review we analyze scaling relationships related to energy ...
-
(NATL ACAD SCIENCES, 2007-06-26)Complex ecological and economic systems show fluctuations in macroscopic quantities such as exchange rates, size of companies or populations that follow non-Gaussian tent-shaped probability distributions of growth rates ...
-
(PALEONTOLOGICAL SOC INC, 2007)We assessed selective extinction patterns in bivalves during a late Neogene mass extinction event observed along the temperate Pacific coast of South America. The analysis of 99 late Neogene and Quaternary fossil sites ...
-
(WILEY-BLACKWELL, 2011)P>Paleobotanists have long used models based on leaf size and shape to reconstruct paleoclimate. However, most models incorporate a single variable or use traits that are not physiologically or functionally linked to ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-07)The most important processes shaping communities are likely to leave observable imprints on their spatial structure. The net outcome of positive and negative interactions among plants has been proposed to vary inversely ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-08-01)We evaluate the impact of exceptionally sparse plant cover (0-20%) and rainfall (2-114 mm/yr) on the stable carbon and oxygen composition of soil carbonate along elevation transects in what is among the driest places on ...
-
(Wiley, 2020)The Cape Horn Biosphere Reserve, one of the last wild areas of the planet, is not exempt from the pressures of global change, such as non-native species introductions. During 2018 and 2019 we studied the Robalo river basin ...
-
(Frontiers Media, 2020)High-elevation tropical lakes are excellent sentinels of global change impacts, such as climate warming, land-use change, and atmospheric deposition. These effects are often correlated with temporal and spatial beta diversity ...
