Falcy, Matthew R.; Estades Marfán, Cristián (2007)The establishment of biological corridors between two otherwise isolated habitat patches is a common yet contentious strategy for conserving populations in fragmented landscapes. We compared the effectiveness of corridors ...

Zaviezo, Tania; Grez Villarroel, Audrey; Estades Marfán, Cristián; Pérez, Astrid (BLACKWELL, 2006-12)1. Habitat loss and fragmentation are the main causes of changes in the distribution and abundance of organisms, and are usually considered to negatively affect the abundance and species richness of organisms in a landscape. ...

Tomasevic Vukasovic, Jorge; Estades Marfán, Cristián (ELSEVIER SCIENCE BV, 2008-03-20)Fragmentation combined with habitat loss can affect population persistence mainly by isolating habitat fragments. However, this isolation depends, in part, on the species’ perception of the surrounding matrix compared to ...

Uribe Miranda, Sandra Verónica (Universidad de Chile, 2007)La zona central de Chile presenta serios problemas de conservación debido a una fuerte presión antrópica que ha generado pérdida de hábitat; ésta a su vez, ha provocado disminuciones de las poblaciones de vertebrados e ...

Pernollet, Claire A.; Pávez, Eduardo F.; Estades Marfán, Cristián (2013)The Torrent Duck (Merganetta armata) inhabits the torrential rivers of the Andean mountains. As part of a long-term study, two rivers important for hydroelectric production were surveyed in Central Chile. Monthly indices ...

López Alfaro, Claudia; Estades Marfán, Cristián; Aldridge, Dennis K.; Gill, Robin M.A. (2012)One of the greatest challenges for conservation biology is providing solutions for endangered species in modern landscapes, usually with deficient biological information on how species respond to landscape disturbances. ...

Fuentes Allende, Nicolás; Vielma, André; Paulsen, Katheryne; Arredondo, Cristóbal; Corti, Paulo; Estades Marfán, Cristián; González, Benito A. (Elsevier, 2016)Areas with high shrub and grass cover are scarce and important for arid-land ungulates. Unfortunately, agricultural activities are often concentrated in such areas causing ungulates either to include croplands as foraging ...
-
González Gómez, Paulina L.; Estades Marfán, Cristián (2009)In many hummingbird species there is an opposite pattern of sexual dimorphism in bill length and other morphometric measures of body size. These differences seem to be closely related with differences in foraging ecology ...

Estades Marfán, Cristián; Escobar, Martín A H; Tomasevic, Jorge A.; Vukasovic, María Angélica; Páez, Mauricio (2006)We used variable-radius point counts and mist-netting to estimate forest bird abundances in the Maule Region of South Central Chile. Mist-netting detected a total of 25 species over 3 years and 3 seasons per year (Winter, ...

Iranzo, Esperanza C.; Traba, Juan; Acebes, Pablo; González, Benito A.; Estades Marfán, Cristián; Mata, Cristina; Malo, Juan E. (PLoS ONE, 2013)Competition arises when two co-occuring species share a limiting resource. Potential for competition is higher when species have coexisted for a short time, as it is the case for herbivores and livestock introduced in ...

Uribe, Sandra V.; Chiappe, Romina; Estades Marfán, Cristián (Sociedad de Biologia de Chile, 2017)© The Author(s). 2017. Background: Monitos del monte (Dromiciops gliroides) are old-growth forest specialists and, thus, believed to be very sensitive to habitat transformation, although some recent studies show some level ...
-
Acuña, María Paz; Estades Marfán, Cristián (2011)Plantation clearcuts represent an important habitat for many open-area wildlife species – including conservation-concern species – in landscapes dominated by industrial forests. However, due to the ephemeral nature of ...
-
Latorre Lerma, Valentina (Universidad de Chile, 2013)La pérdida de hábitat en los valles del extremo norte de nuestro país ha traído graves consecuencias en las especies nativas, tanto de flora como de fauna. Es así como Eulidia yarrellii, el picaflor de Arica, pasó de estar ...
-
Simonetti Zambelli, Javier Andrés; Grez Villarroel, Audrey; Estades Marfán, Cristián (Society for Conservation Biology, 2013)La Convención sobre Diversidad Biológica (CDB) espera que las plantaciones forestales contribuyan a la conservación de la biodiversidad. Un sotobosque bien desarrollado en plantaciones forestales puede servir como hábitat ...
-
Uribe, Sandra; Estades Marfán, Cristián (Sociedad de Biologia de Chile, 2014)© 2014 Uribe and Estades; licensee Springer.Background: In Chile, most of the timber industry depends on Monterey pine (Pinus radiata (D. Don.)) plantations, which now cover more than 1.5 million ha. In spite of the intensive ...
-
Tomasevic Vukasovic, Jorge; Estades Marfán, Cristián (2006)The ecology of secondary cavity-nesting birds (SCN) has been a matter of great interest for many years throughout the world, in part because of the direct and strong relationship between the breeding biology of these species ...
-
González Gómez, Paulina L.; Estades Marfán, Cristián; Simonetti Zambelli, Javier Andrés (SPRINGER, 2006-05)Habitat fragmentation modifies ecological patterns and processes through changes in species richness and abundance. In the coastal Maulino forest, central Chile, both species richness and abundance of insectivorous birds ...

Villaseñor, Nélida R.; Escobar, Martín A.H.; Estades Marfán, Cristián (2013)Animal translocation is a popular tool in wildlife management. It is frequently used to solve human-animal conflicts and recently has been applied as a mitigation tool when animals inhabit land desired for development. ...
