(Archivos Latinoamericanos Nutricion, 2014)The Latin American Network of Food Composition Data System (LATINFOODS) is the regional data center of the global network "International Network on Food Data Systems" (INFOODS) co-sponsored by the Food and Agriculture ...
-
(Elsevier, 2016)Floating seaweeds are important dispersal vehicles for many organisms in cold-temperate waters between latitudes 30 and 60. Molecular studies suggested that long-distance rafting of seaweeds is more prevalent at the polar ...
-
(Springer, 2020)Latitudinal diversity patterns in marine species are commonly estimated from literature records, which at times are incomplete and/or biased. Advances in molecular phylogenetics have contributed to avoid this bias, clarifying ...
-
(Elsevier, 2020)Latitudinal gradients are well-suited systems that may be helpful explaining distribution of haemosporidian parasites and host susceptibility. We studied the prevalence, diversity and drivers of haemosporidian parasites ...
-
(Elsevier, 2020)Human-dominated environments alter the availability and quality of resources for many species, especially for scavengers that have large home ranges and plastic foraging behaviors that enable them to exploit novel resources. ...

-
(Springer, 2020)New composites formed by layered hybrid TiO2(stearic acid) (LHTiO2) and, Cu2O nanoparticles were studied as photocatalysts that extend the response range to light visible for the evolution of hydrogen and the degradation ...
-
(Cambridge University Press, 2019)For a large family of properties of homogeneous spaces, we prove that such a property holds for all homogeneous spaces of connected linear algebraic groups as soon as it holds for homogeneous spaces of SLn with finite ...
-
(American Chemical Society, 1981-11-20)The seeds of Sophora mcrcrocarpo Sm. (Fabaceae) are a promising source of edible oil (l), and contain matrine, N-methylcytisine and baptifoline (2). Glc analyses of the leaves of this species suggested that matrine is ...
-
(Copernicus Gesellschaft MBH, 2018)Pouteria splendens (A. DC.) Kuntze, the Chilean lucumo, is an endemic tree and the only member of the Sapotaceae family in Chile. It is considered an endangered species as a consequence of its restricted distribution and ...
-
(SPRINGER, 2007-05)Leaf litter accumulation can have either positive, negative or neutral effects on seed germination and seedling recruitment. In montane woodlands of the Mediterranean zone of central Chile, large amounts of leaf litter ...
-
(Elsevier, 2012)The genus Drimys is distributed in Chile from semi-arid zones to sub-Antarctic forests; there are three species of this tree, D. andina, D. confertifolia and D. winteri, the latter with varieties chilensis and winteri. ...

(2007)Fragmentation of the Maulino forest implies significant habitat loss, as well as the modification of the microclimatic conditions of the remaining forest patches. Fragments are drier, hotter and receive more light than the ...
-
Leaf traits and leaf herbivory variation between centre and north-edge populations of Drimys winteri (Universidad de Chile, 2017)
-
(CAMBRIDGE UNIV PRESS, 2008-04)We consider Ledrappier's dynamical system, which was the first example of a Z(2)-action which is 2-mixing but not 3-mixing. Our main result is that, excluding certain small 'constructible' sets, the system is mixing of ...
-
(2011)During tissue morphogenesis and differentiation, cells must self-renew while contemporaneously generating daughters that contribute to the growing tissue. How tissues achieve this precise balance between proliferation and ...
-
(Taylor & Francis, 2021)Two genera of fish, Orestias (Cyprinodontidae) and Trichomycterus (Trichomicteridae), inhabit in the Lauca National Park, UNESCO Biosphere Reserve, located at the Andes highlands in northern Chile. The present study ...
-
(Elsevier B.V., 2016)© 2015 The Authors.Forests worldwide are threatened by various environmental and anthropogenic hazards, especially tropical forests. Knowledge on the impacts of these hazards on forest structure and dynamics has been ...
-
(Wilson Ornithological Soc, 2016)Agonistic behavior in woodpeckers has been described for a wide range of species, although previous studies have not reported aggressive encounters resulting in the death of adults. In this study, we provide the first ...
