Silva, Claudia A.; Simonetti Zambelli, Javier Andrés (2009)Folivory is lower in forest fragments of the Maulino forest than in continuous stands. We experimentally assessed whether depressed folivory is related to a reduction in foliar palatability caused by the more xeric ...

Poch Velasco, Tomas Javier (Universidad de Chile, 2012)A pesar de ser estructuralmente más simples y empobrecidas en especies que los bosques nativos, las plantaciones agroforestales pueden actuar como hábitat secundario para especies nativas y sostener algo de biodiversidad. ...

Poch, Tomás J.; Simonetti Zambelli, Javier Andrés (2013)Increasing evidence suggests that, depending on the structural complexity of a plantation, it can act as complementary habitat for insectivore birds and mammals. The magnitude of interactions such as insectivory, in turn, ...

Riquelme, Maira; Salgado, Rodrigo; Simonetti Zambelli, Javier Andrés; Landaeta Aqueveque, Carlos; Fredes Martínez, Fernando; Rubio, André V. (MDPI, 2021)Land-use changes are one of the most important drivers of zoonotic disease risk in humans, including helminths of wildlife origin. In this paper, we investigated the presence and prevalence of intestinal helminths in wild ...

Bustamante Araya, Ramiro; Simonetti Zambelli, Javier Andrés (2005)Forest fragmentation facilitates the invasion of exotic species. This threat may be especially severe if forest fragments are surrounded by plantations of exotic species like Pinus radiata, an aggressive colonizer and ...

Is top-down control by predators driving insect abundance and herbivory rates in fragmented forests? De La Vega, Xaviera; Grez Villarroel, Audrey; Simonetti Zambelli, Javier Andrés (2012)The effects of forest fragmentation on ecological interactions and particularly on food webs have scarcely been analysed. There is usually less herbivory in forest fragments than in continuous forests. Here we hypothesize ...

Repetto Giavelli, Fiorella; Cavieres, Lohengrin A.; Simonetti Zambelli, Javier Andrés (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 ...
-
García, Valentina; Simonetti Zambelli, Javier Andrés; Becerra, Pablo (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 ...

Crespin, Silvio; Simonetti Zambelli, Javier Andrés (Elsevier, 2016)Land use change can reduce the wealth and wellbeing of a nation by modifying its biodiversity. We used value transfer methodology to estimate changes in the value of ecosystem services provided by natural ecosystems in El ...
-
Ebensperger, Luis A.; Simonetti Zambelli, Javier Andrés (Walter de Gruyter GmbH, 1996)We contrasted two approaches to test the hypothesis that microclimate influences selection of microhabitat by two species (Abrothryx longipilis and Phyllotis darwini) of nocturnal rodents of central Chile. Microhabitats ...
-
Ramos, Carolina; Simonetti Zambelli, Javier Andrés; Flores, Jose D.; Ramos Jiliberto, Rodrigo (2008)In the fragmented Maulino forest (in Central Chile), differences in the relative frequencies of species between seedlings and mature trees are strong indicators of a changing replacement dynamics in the community. Stationary ...

Valdivia, Carlos E.; Bahamondez, Alejandra; Simonetti Zambelli, Javier Andrés (2011)Background - Habitat fragmentation may have detrimental effects on both plant-mutualistic (i.e. pollination) and plant-antagonistic interactions (i.e. foliar herbivory). Such double negative effects may lead to a change ...

Barceló, Matías; Simonetti Zambelli, Javier Andrés (Neotropical Ornithological Society, 2017)© The Neotropical Ornithological Society. The Chestnut-throated Huet-huet (Pteroptochus castaneus) is a poorly known species, endemic to Chile and Argentina. Here we describe observations made during eight days on a nest ...

Arenas Rodriguez, Kathia Deborah (Universidad de Chile, 2022)Diversas actividades humanas pueden afectar a la fauna silvestre en distintas dimensiones. Entre estas actividades, la ganadería es una fuente de conflictos humano-vida silvestre debido, entre otros factores, a la depredación ...

Agüero Teara, Teresa Doris (Universidad de Chile., 1989)En esta tesis se estudió experimentalmente, si las frecuencias de captura de pequeños mamíferos, son realmente un estimador insesgado para determinar selección y uso de microhabitantes.
-
Contreras Abarca, Rocío (Universidad de Chile, 2019-09)Los perros de guarda de ganado (PGG) son un método usado para disminuir las pérdidas de ganado causadas por amenazas como depredación por carnívoros silvestres, que consecuentemente reducen la persecución de carnívoros. ...

Roldán, Alejandra I.; Simonetti Zambelli, Javier Andrés (2001)We studied plant-animal interactions and vegetation structure in two geographically close tropical Bolivian forests subjected to different hunting intensities. We hypothesized that reduction of mammals of > 1 kg in an ...

Bahamondez Alvarado, Alejandra Patricia (Universidad de Chile, 2007)La fragmentación de los bosques puede alterar la eficiencia de los servicios de polinización al cambiar la riqueza y abundancia de visitantes florales. La fragmentación puede así comprometer el éxito reproductivo de las ...
