-
(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 ...
-
(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 ...
-
(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 ...
-
(Wiley, 2020)Air pollution problems can be large, complex, and ill-structured. They can vary from location to location and combine many complex components: urban expansion, increasing vehicles and industrial emissions, biomass burning, ...
-
(Springer Verlag, 2018)© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. In this work some possibilities for deriving a local electrophilicity are studied. First, we consider the original definition proposed by Chattaraj, Maiti, and ...
-
(ELSEVIER, 2006-04-15)Opuntia scrublands are important ecological-economic systems in the Andean area. They perform a major role protecting slopes against erosion, improving the soil properties and providing a variety of products employed in ...
-
(Springer New York, 1997)
-
(Walter de Gruyter GMBH, 2021)In this article, we study the obstructions to the local-global principle for homogeneous spaces with connected or abelian stabilizers over finite extensions of the field C ((x; y)) of Laurent series in two variables over ...
-
(The Rockefeller University, 1999)Using Ba2 1 as a probe, we performed a detailed characterization of an external K 1 binding site located in the pore of a large conductance Ca2 1-activated K 1 (BKCa) channel from skeletal muscle incorporated into planar ...
-
(2007)We study the properties of junctions created by the crossing of N identical branches of linear discrete networks. We reveal that for N > 2 such a junction creates a topological defect and supports two types of spatially ...
-
(2012)We examine localization of light in nonlinear (Kerr) kagome lattices in the shape of narrow strips of varying width. For the narrowest ribbon, the band structure features a flat band leading to linear dynamical trapping ...
-
(ELSEVIER, 2008-10-13)We study localized modes on a single Ablowitz-Ladik impurity embedded in the bulk or at the surface of a one-dimensional linear lattice. Exact expressions are obtained for the bound state profile and energy. Dynamical ...
-
(1974)The effects due to localized spin fluctuations (LSF) in dilute superconducting alloys are investigated. Expressions for the critical temperature Tc as function of impurity concentration nI and the specific heat jump at the ...
-
(Optical Soc Amer, 2020)We address the issue of nonlinear modes in a two-dimensional waveguide array, spatially distributed in the Lieb lattice geometry, and modeled by a saturable non-linear Schrodinger equation. In particular, we analyze the ...
-
(1995)Deuterium quadrupole splittings from the aromatic ring of a series of deuterium labeled n-alkylpyridinium ions with linear n-alkyl groups from Ci to Cie have been measured using 2H-NMR spectroscopy. These splittings were ...
