(Frontiersin Plant Science, 2015)Polyols are enzymatically-produced plant compounds which can act as compatible solutes during periods of abiotic stress. Nicotinamide adenine dinucleotide+-dependent SORBITOL DEHYDROGENASE (SDH, E. C. 1.1.1.14) from ...
-
(SPRINGER, 2008-04)Invasive species can increase fire frequency and intensity, generating favorable conditions for their self-perpetuation. Mediterranean south-central Chile may be especially prone to the effects of invasive species on fire ...
-
(BLACKWELL, 2006-01)In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...
-
(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...
-
(Springer, 2020)Shifts in species distributions are among the observed consequences of climate change, forcing species to follow suitable environmental conditions. Using species distribution models (SDMs), we aimed at predicting trends ...
-
Predicting effects of ecosystem engineering on species richness along primary productivity gradients (ELSEVIER, 2010)Physical ecosystem engineering is the process by which some species change the distribution of materials and energy in ecosystems. Although several studies have shown that this process is a driver of local species ...
-
(Public Library Science, 2015)Prenatal stress causes predisposition to cognitive and emotional disturbances and is a risk factor towards the development of neuropsychiatric conditions like depression, bipolar disorders and schizophrenia. The extracellular ...
-
(ELSEVIER, 2005-12)In the past decade, there has been growing concern about the rapid degradation of marine ecosystems due to anthropogenic causes. Consequently, identifying priority areas for the conservation of marine biodiversity has ...
-
(Ediciones Universidad de L a Serena, 2006)En este trabajo se describen algunas características generales de los humedales, con énfasis en las vegas andinas. En particular, se muestran los resultados de varios estudios realizados entre los años 1994 y 2003 en la ...
-
(Biomed Central, 2015)Background: Astaxanthin is a potent antioxidant with increasing biotechnological interest. In Xanthophyllomyces dendrorhous, a natural source of this pigment, carotenogenesis is a complex process regulated through ...

Prólogo (2006-11)
-
(Elsevier, 2015)We study the long-time wave transport in correlated and uncorrelated disordered 2D arrays. When a separation of dimensions is applied to the model, we find that the previously predicted 1D random dimer phenomenology also ...
-
(Elsevier, 2015)We present a unified model of electrophilicity and nucleophilicity that considers the electrophile/nucleophile pair in an interacting regime, thereby avoiding the arbitrariness of defining them as the opposite ends of a ...
-
(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 ...
