Valdivia, Carlos E.; Simonetti Zambelli, Javier Andrés (2011)Negative density-dependent relationships in plant communities are currently claimed as an important mechanism for the maintenance of plant diversity. However, anthropogenic perturbations such as forest fragmentation might ...

Veloso,; Celis Diez, Juan L.; Guerrero, Pablo C.; Méndez, Marco; Iturra, Patricia; Simonetti Zambelli, Javier Andrés (2005)The description of a new species of Eupsophus, from Los Queules National Reserve (35° 59' S, 72° 41'W) adds a new endemic taxon to the fauna of telmatobines (Amphibia, Leptodactylidae) of Chile, and extends the geographical ...

Muñoz, Alejandra E.; Simonetti Zambelli, Javier Andrés (Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2013)Guanaco (Lama guanicoe), the only native ungulate of Tierra del Fuego, uses the forests more extensively after the introduction of sheep. It is presumed that the regeneration of lenga (Nothofagus pumilio) is hampered by ...

Uribe Rivera, David Eduardo (Universidad de Chile, 2015)Desarrollar modelos que permitan predecir de manera confiable los efectos del cambio climático sobre la biodiversidad es una prioridad para su gestión. Problemas comunes a la precisión predictiva de los Modelos de ...
-
Gómez Fernández, Nicolás Antonio (Universidad de Chile, 2013)Este trabajo determina si existe una valoración por incrementos en biodiversidad a través de la estimación de la disposición a pagar (DAP) por conservar biodiversidad en plantaciones forestales mediante el Método de ...
-
Simonetti Zambelli, Javier Andrés (Universidad de Chile., 1979)Se intenta explicar la divergencia filotina sobre la base del análisis cuantitativo de varias características corporales, en especial dentarias. Se utiliza material de once de las doce especies de Phyllotis, las tres ...
-
Vergara Egert, Pablo; Simonetti Zambelli, Javier Andrés (Association of Field Ornithologists, 2004)Cover at nesting sites selected by breeding birds can reduce the risk of nest predation. Using artificial nests, we tested whether dense cover reduces nest predation upon understory birds (rhinocryptids) in temperate forest ...
-
Guerrero Carvajal, Samuel Ignacio (Universidad de Chile, 2022)Una de las más drásticas perturbaciones generadas por el ser humano sobre los ecosistemas, es la transformación de ecosistemas naturales en ecosistemas urbanos. Como consecuencia, las especies se han visto desplazadas y ...
-
Valdivia Prats, Carlos Eduardo (Universidad de Chile, 2003)Se estudió el efecto de la fragmentación del bosque sobre la polinización y éxito reproductivo de Lapageria rosea, una planta auto-compatible y endémica de 105 bosques templados de Sudamérica. La abundancia de flores y ...
-
Nájera, Andrea; Simonetti Zambelli, Javier Andrés (2010)The occurrence of fauna in commercial plantations is often associated with structural complexity. Through a meta-analysis, we tested whether the structural complexity of plantations could enhance bird species assemblages ...
-
Osorio Carrasco, Amanda Teresa (Universidad de Chile., 2022)La presión antropogénica sobre los ecosistemas terrestres, en un contexto de perdida de ecosistemas y cambio climático, corresponde a un desafío a nivel regional y de coordinación de esfuerzos a nivel mundial. Para esto, ...

Rodríguez San Pedro, Annia; Simonetti Zambelli, Javier Andrés (2013)We assessed foraging activity of insectivorous bats in a fragmented landscape of central Chile including native temperate forest, forest fragments, commercial pine plantations and local human settlements. Overall bat ...
-
Vergara, Pablo M.; Simonetti Zambelli, Javier Andrés (Elsevier, 2003)Fragmentation of forest landscapes can raise the intensity of nest predation by increasing the abundance and richness of generalist or introduced predators. Understory foraging birds, such as rhinocryptids, can be highly ...
-
Püschel-Hoeneisen, Nicole; Simonetti Zambelli, Javier Andrés (2012)The need for conservation outside protected areas has prompted the modifi cation of productive practices to allow the maintenance of wild biota in productive landscapes such as those associated to timber production. Forest ...
-
Vásquez Salfate, Rodrigo; Bustamante Araya, Ramiro; Simonetti Zambelli, Javier Andrés (1995)Comparative studies of granivory intensity across different arid and semi‐and regions of the world have assumed homogeneity of conditions over large geographical areas, despite the existence of evident heterogeneities at ...
-
Acosta Jamett, Gerardo; Simonetti Zambelli, Javier Andrés (2004)Native forests in Chile have been replaced by exotic plantations, generating a mosaic of forest fragments immersed in a matrix of plantations and farms. This landscape change could affect habitat availability for native ...
-
Simonetti Zambelli, Javier Andrés; Grez Villarroel, Audrey; Celis Diez, Juan L.; Bustamante Araya, Ramiro (2007)Forest fragmentation alters plant-animal interactions, including herbivory. Relying manipulative experiments, we test if the reduction in insect herbivory associated with forest fragmentation translates into increased ...

Gallardo-Santis, Andrea; Simonetti Zambelli, Javier Andrés; Vásquez Salfate, Rodrigo (2005)Climbing ability can be a major component of the capability of terrestrial mammals to use vertical habitats. Previous studies suggest that small mammals from central Chile have low climbing capabilities. However, those ...
