Osorno, José L.; Morales, Judith; Moreno, Juan; Merino, Santiago; Tomás, Gustavo; Vásquez Salfate, Rodrigo (SPRINGER, 2006-10)We present evidence of differential maternal allocation to eggs in response to manipulated male attractiveness in the migratory pied flycatcher (Ficedula hypoleuca). We manipulated the size of a male secondary sexual trait, ...

Vetterlein, Claudia; Vásquez Salfate, Rodrigo; Bolaños, Karen; Acosta, Gerardo A.; Guzman, Fanny; Albericio, Fernando; Celis, Freddy; Campos, Marcelo; Kogan Bocian, Marcelo; Araya, Eyleen (Elsevier, 2018-06)We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels-Alder adducts of different lengths (n = 4 and n = 9). The functionalized GNRs were irradiated ...

Botero Delgadillo, Esteban; Vásquez Salfate, Rodrigo (SOC Brasileira Ornitología, 2016-06)Nesting birds commonly incorporate feathers into nest linings given their insulation properties. Although use of feathers is common among swallows, here we provide the first recording of nests built almost completely with ...
-
González Gómez, Paulina L.; Vásquez Salfate, Rodrigo (BLACKWELL, 2006-08)The foraging ecology of hummingbirds involves the exploitation of a high number of patchily distributed flowers. This scenario seems to have influenced capabilities related to learning and memory, which help to avoid ...

Suárez Villota, Elkin; González Wevar, Claudio; Gallardo, Milton; Vásquez Salfate, Rodrigo; Poulin, Elie (Academic Press-Elsevier, 2016)Endemic to South America, octodontid rodents are remarkable by being the only mammal taxa where allotetraploidy has been documented. The taxon's extensive morpho-physiological radiation associated to niche shifts has allowed ...

González Gómez, Paulina L.; Vásquez Salfate, Rodrigo; Bozinovic, Francisco (AMER ORNITHOLOGISTS UNION, 2011-01)We assessed how individual foraging preferences and cognitive performance affect foraging bout interval and the flexibility of foraging behavior in the nectarivorous Green-backed Firecrown (Sephanoides sephaniodes). Our ...

van Dongen, Wouter F. D.; Maldonado, Karin; Sabat Kirkwood, Alejandro Pablo; Vásquez Salfate, Rodrigo (OXFORD UNIV PRESS INC, 2010-08-06)Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is revealing the adaptive significance of personalities, although the mechanisms driving ...

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 ...

Merino, Santiago; Moreno, Juan; Vásquez Salfate, Rodrigo; Martínez, Javier; Sánchez Monsalvez, Inocencia; Estades Marfán, Cristián; Ippi, Silvina; Sabat Kirkwood, Alejandro Pablo; Rozzi, Ricardo; Mcgehee, Steven (BLACKWELL, 2008-05)The existence of latitudinal gradients in species richness and their abundance is known for many free living organisms but few cases have been reported for parasitic diseases. In addition, asymmetries between the Northern ...

Pérez Álvarez, María José; Vásquez Salfate, Rodrigo; Moraga, Rodrigo; Santos Carvallo, Macarena; Kraft, Sebastián; Sabaj Diez, Valeria; Capella, Juan; Gibbons, Jorge; Vilina, Yerko; Poulin, Elie (Elsevier, 2018-05)Coastal resident and pelagic nonresident bottlenose dolphins, Tursiops truncatus, have been described in north-central Chile. Using long-term residence data (over 13 years of photo-identification) and genetic mtDNA ...

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 ...

Soto, Gerardo; Vergara, Pablo M.; Smiley, Ashley; Lizama, Marlene E.; Moreira Arce, Darío; Vásquez Salfate, Rodrigo (Wilson Ornithological Soc, 2016)Agonistic behavior in woodpeckers has been described for a wide range of species, although previous studies have not reported aggressive encounters resulting in the death of adults. In this study, we provide the first ...
