Seedling Mortality and Herbivory Damage in Subtropical and Temperate Populations: Testing the Hypothesis of Higher Herbivore Pressure Toward the Tropics
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Herbivory rates are generally thought to be higher in tropical than in temperate forests. Nevertheless, tests of this biogeographic prediction by comparing a single plant species across a tropical-temperate range are scarce. ...
Global climate change and small mammal populations in north-central Chile
(Oxford University Press, 2011-12)
Desde 1989, hemos estudiado las poblaciones de micromamíferos en un sitio semiárido en el norte de Chile, mediante un complejo de grillas de trampeo-vivo a gran escala. La exclusión selectiva de depredadores vertebrados ...
El Niño Southern Oscillation drives conflict between wild carnivores and livestock farmers in a semiarid area in Chile
(Academic Press Ltd - Elsevier Science Ltd, 2015-09-08)
The warm phase of El Niño-Southern Oscillation (ENSO) events results in greatly elevated rainfall in north-central Chile, with dramatic effects on small mammals and vertebrate carnivore abundances. In ensuing cool phases ...
Comparison of animal biodiversity in three livestock systems of open environments of the semi-arid Chaco of Argentina
(Australian Rangeland Society, 2015-07)
Increasing global food demand requires the exploration of agricultural production systems that minimise the conflict between food production and biodiversity conservation. Cattle ranching is a main land-use in tropical and ...
Effects of herbivory and patch size on tree seedling survivorship in a fog-dependent coastal rainforest in semiarid Chile
(2007)
The landscape (matrix) surrounding habitat fragments critically affects the biodiversity of those fragments due to biotic interchange and physical effects. However, to date, there have been only a limited number of studies ...
Reduced herbivory during simulated ENSO rainy events increases native herbaceous plants in semiarid Chile
(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 ...
Impacts of socio-political boundaries on small desert mammals of west-central Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2016-05)
Human-induced land degradation modifies the structure of habitat boundaries, which may have consequences for ecosystem functioning. We determined the influence of socio-political boundaries defined for a protected area ...
Temporal Variation of Trypanosoma cruzi Infection in Native Mammals in Chile
(2010)
In the present study, we compared Trypanosoma cruzi infection in four native mammals from a hyperendemic
area of Chagas disease in Chile for two different periods to assess the occurrence of interannual variation (1999–
2000 ...
