(ELSEVIER SCI LTD, 2005-05)We show how Chilean forest bird species richness, abundance and guild structure changes as a function of structural properties of forest stands. We surveyed bird assemblages in two old-growth (>200 years), two mid-successional ...

(Elsevier Ltd, 1997)The intercalation of poly(ethylene oxide) (PEO) in molybdenum sulfide (MoS2) forms the nanocomposites LixMoS2(PEO)0.5 and LixMoS2(PEO)1.0. The lithium ion diffusivity in PEO-containing phases, which depends on both PEO and ...
-
(SOCIEDADE BRASILEIRA FISICA, 2006-03)Cluster architecture and lithium motion dynamics are investigated in nanocomposites formed by the intercalation of lithium and a dialkylamine (diethylamine, dibutylamine and dipentylamine) in molybdenum disulfide by means ...
-
(Elsevier , Science Ltd., 2007-05-31)Films of composites of chitosan/poly(aminopropyltriethoxysilane)/poly(ethylene oxide) (CHI/pAPS/PEO) containing a fixed amount of lithium salt are studied. The ternary composition diagram of the composites, reporting ...
-
(2009)Central Chile differs from other areas with Mediterranean-type climate by the scarcity of natural wildfires. The Chilean matorral is highly invaded by alien plant species from other Mediterranean zones of the world, where ...
-
(2003)In unpolluted regions, where inorganic nitrogen (N) inputs from the atmosphere are minimal, such as remote locations in southern South America, litterfall dynamics and N use efficiency of tree species should be coupled to ...
-
(Elsevier, 2014)Twenty eight out of 44 Chilean freshwater fishes have been considered to fall within the vulnerable or threatened category. Thus, information about the biology, ecology and the effects of the anthropic activity on these ...
-
(Universidad de Chile, 2003)Uno de los principales problemas de contaminación atmosférica que la ciudad de Santiago, es el MP16 y PTS. Este material articulado que está relacionado con una serie de especies orgánicas e inorgánicas, puede afectar ...
-
(Springer, 2011)We studied lizard assemblages assessing abundance, richness, and nestedness in a fragmented landscape of central Chile including native temperate forest, forest fragments, and commercial pine plantations. Fragmentation and ...
-
(Wiley, 2020)Vertebrate predation by invertebrates has been classically underexplored and thus underestimated, despite the fact that many arthropods consume vertebrates. To shed some light on the relevance that spider predation may ...
-
(Nature, 2020)Studies of host-parasite relationships largely benefit from adopting a multifactorial approach, including the complexity of multi-host systems and habitat features in their analyses. Some host species concentrate most ...
-
(Centers Disease Control & Prevention, 2022)We assessed 4 lizard species in Chile for Trypanosoma cruzi, the causative agent of Chagas disease, and 1 species for its ability to transmit the protozoan to uninfected kissing bugs. All lizard species were infected, and ...
-
(Universisdad de Chile, 2003)La linea lateral es un sistema mecanosensorial presente en peces y anfibios compuesta por órganos denominados neuromastos. Los neuromastos, a su vez, se componen de células de soporte que rodean un grupo de células ...

(2016)Native vegetation development in forestry plantations may depend on seed dispersal, seed predation and seed germination. These processes may depend on distance to native forest fragments and presence of understory. In this ...
