Armesto, Juan J.; Hinojosa Opazo, Luis; Villagrán Moraga, Carolina (BLACKWELL, 2006-02)Aim We ask whether contemporary forests of the Chilean Coastal Range can be considered to be direct and conservative descendants of pre-Pleistocene palaeofloras that occurred in southern South America from the Palaeogene ...

Breeding biology of the Thorn-tailed Rayadito (Furnariidae) in south-temperate rainforests of Chile Moreno, Juan; Merino, Santiago; Vásquez Salfate, Rodrigo; Armesto, Juan J. (COOPER ORNITHOLOGICAL SOC, 2005-02)We conducted a study of the breeding biology of the Thorn-tailed Rayadito (Aphrastura spinicauda) in secondary forests on the continental island of Chiloe (42degreesS), southern Chile. Rayaditos are small insectivorous ...

Rovere, Adriana E.; Smith Ramírez, Cecilia; Armesto, Juan J.; Premoli, Andrea C. (SOCIEDAD BIOLOGIA CHILE, 2006-06)Plant breeding systems are considered to reflect species' life history characteristics, selection due to biotic or abiotic factors, pollination conditions, or a combination of these. Reproductive systems may vary over ...

Smith Ramírez, Cecilia; Martínez, P.; Núñez, M.; González, C.; Armesto, Juan J. (BLACKWELL, 2005-04)Species richness and taxonomic composition of pollinator assemblages are documented for 26 plant species from temperate rain forests of northern Chiloe Island, southern Chile (42 degrees 30'S). We investigated the patterns ...

Chacón, Paulina; Armesto, Juan J. (SPRINGER, 2006-01)Carbon-based secondary compounds (CBSCs), such as phenols or tannins, have been considered as one of the most important and general chemical barriers of woody plants against a diverse array of herbivores. Herbivory has ...

Carmona, Martín R.; Pérez, Sandra E.; Pérez, Cecilia A.; Fariña, José M.; Armesto, Juan J. (Sociedad de Biología de Chile, 2008-06)El flujo de entrada de nitrógeno (N) en ecosistemas de bosques templados de la Isla de Chiloé puede ocurrir en una proporción importante vía fijación no simbiótica (FNS). Debido a que este proceso es llevado a cabo por ...

Méndez, Marco; Torres Pérez, Fernando; Correa, Claudio; Soto, Eduardo R.; Núñez, José; Veloso Martínez, Alberto; Armesto, Juan J. (BRITISH HERPETOL SOC, 2006-01)Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...

Reid, Sharon; Armesto, Juan J. (Elsevier, 2011)Studies of plant-frugivore interactions are important for identifying the roles that biotic seed vectors play in seed dispersal, and ultimately plant recruitment. In a subandean shrubland of central Chile, 50% of total ...

Willson, Mary F.; Armesto, Juan J. (SOCIEDAD BIOLOGIA CHILE, 2006-06)In recent years natural history has been derided by some scientists as an old-fashion endeavor that does not follow the model of "hard" science and therefore should be considered "dead" and replaced by modern ecology, ...

Díaz, María Francisca; Armesto, Juan J. (SOCIEDAD BIOLOGIA CHILE, 2007-03)Successional shrublands created by clearcutting and burning of forests are frequent in Chiloe Island and surrounding mainland in southern Chile. These areas are characterized by seasonally waterlogged soils, and vegetation ...

Díaz, Iván; Armesto, Juan J.; Willson, Mary F. (BLACKWELL, 2006-02)We studied the effects of fragment size, vegetation structure and presence of habitat corridors on the reproductive success of the Des Murs' Wiretail (Sylviorthorhynchus desmursii Des Murs, Furnariidae), a small (10 g) ...

Pérez, Cecilia A.; Carmona, Martín R.; Armesto, Juan J. (Ecological Society of Australia, 2010)Heterotrophic nitrogen fixation is a key ecosystem process in unpolluted, temperate old-growth forests of southern South America as a source of new nitrogen to ecosystems. Decomposing leaf litter is an energy-rich substrate ...

del-Val, Ek; Armesto, Juan J.; Barbosa, Olga; Christie, Duncan A.; Gutiérrez, Alvaro G.; Jones, Clive G.; Marquet, Pablo A.; Weathers, Kathleen C. (SPRINGER, 2006-06)Tree presence in semiarid ecosystems is generally constrained by insufficient annual rainfall. However, in semiarid Chile, rainforest patches dominated by Aextoxicon punctatum are unexpectedly found on coastal mountaintops ...
