Urban areas form a complex, heterogeneous, fragmented mosaic of habitats, including ecosystems in different degrees of alteration. Nevertheless, some species of birds of prey can thrive in cities. But, there is a knowledge gap regarding the species of birds of prey that who inhabit the cities in Chile, especially those that reproduce in it. Hence,...
Environmental education (EE) must be carried out following a permanent programme, and should be a source of inspiration to encourage the incorporation of an ‘environmentalist’ line in other cultural and educational materials. EE has developed in Chile since the 1970s, but slowly, and unconnected with three important actors: the State, the universit...
La educación ambiental (EA) debe llevarse a cabo de acuerdo a un programa permanente, y debe ser fuente inspiradora para que otras materias culturales y educativas se orienten en una línea “ambientalista”. En Chile la EA se ha desarrollado, desde la década del 70 del siglo XX, en forma lenta y no vinculando tres actores relevantes: el estado, las u...
In the past decade, the south of Chile has experienced a considerable increase in recreational fishing, which has brought greater pressure to bear on the ecosystems. One of the more important gaps in recreational fishing management is the availability of a methodological framework that would make it possible to identify and assess areas that are su...
Raptor conservation programs should be based on knowledge of the birds’ ecology in both natural and urban habitats, justifying the inclusion of ecological studies in suburban zones into regional planning initiatives. The objective of this study was to determine the use of diurnal raptors within the habitats of a suburban area of a city in southern...
Cities in general possess limited areas of original vegetation, or even artificial green areas; this results in drastic modification of faunal communities, with reductions in their original abundance and diversity. Nevertheless, some species are able to thrive in cities, including high trophic level species such as raptors. The object of this study...
El objetivo general es realizar un estudio de determinación del peligro aviario para el Aeródromo Carriel Sur (ACS), de la ciudad de Concepción, en el sur de Chile, con el propósito de resguardar la Seguridad Operacional del citado Aeródromo.
Chile has a large number of wetlands that offer a wide variety of refuges and food to waterbird assemblages. This research hypothesizes that these assemblages differ according to the structural characteristics of each type of inland wetland. The object is to identify the structure of these assemblages, evaluating their richness, alpha diversity and...
Diversity of rodents were compared in a priority site of conservation in southern-central Chile through two seasons (winter and spring). Through the use of Sherman traps, the richness and abundance of species present in both the priority site (native forest) and its adjacent habitat (commercial plantation of Eucalyptus globulus) was assessed. There...
La selva valdiviana del sur de Chile, junto al bosque del noroeste del Pacífico en los EE.UU. y a los bosques del sur de Nueva Zelandia, son los únicos bosques frío-templados lluviosos del mundo. La historia posglacial de estos bosques está influenciada por el poblamiento humano y durante el periodo indígena se limitó al uso como leña y madera, con...
Raptor conservation programs should be based on knowledge of the birds’ ecology in both natural and urban habitats, justifying the inclusion of ecological studies in suburban zones into regional planning initiatives. The objectives of this study were (a) to determine the use by diurnal raptors of the habitat in a suburban area of a city in southern...
Geranoaetus polyosoma (Quoy & Gaimard, 1824) is a diurnal raptor widely distributed in South America. Although the trophic ecology of this bird has been more studied in the southern extreme of its range, little information is available on its dietary response to prey supply in desert environments. In the present study, we report on the trophic ecol...
Geranoaetus polyosoma is a diurnal raptor widely distributed in South America. 18 Knowledge of its trophic ecology is biased towards the southern extreme of its range, and little 19 information is available on its dietary response to prey supply in desert environments. In the 20 present study, we report on the trophic ecology of G. polyosoma in a s...
La diversidad biológica es la variabilidad de organismos vivos de cualquier fuente, incluidos los ecosistemas terrestres y marinos; comprende la diversidad dentro de cada especie, entre las especies y de los ecosistemas.

Urbanisation is a dominant demographic trend and an important component of the earth's global transformation. It has unprecedented socioeconomic, cultural and environmental implications, and poses a threat to the conservation of biodiversity, as it can provoke alterations in ecological systems and lead to poor functioning of urban systems as they a...
En las aves el funcionamiento del aparato digestivo difiere según la dieta. En las rapaces, el alimento permanece menos tiempo en el buche que en las aves granívoras, pasando muy rápidamente a la molleja, sección donde la presa es triturada por el estómago muscular separándose las porciones digeribles de las indigeribles. Estas últimas están compue...

En Chile la educación ambiental se ha desarrollado en forma lenta y por caminos no vinculados desde tres actores relevantes: el estado, las universidades, y los organismos no gubernamentales. El bajo interés por su promoción parece deberse al paradigma posmodernista que está permeando una parte de la sociedad chilena y al modelo de desarrollo impue...
Progress in environmental education in Chile has been slow and uncoordinated. The three main actors involved are the State, the universities and non-governmental organisations. The lack of interest in promoting it appears to be due to the post-modernist paradigm which permeates a part of Chilean society, and the dominant development model which rel...
Usually a wetland is presented as a heterogeneous complex, such that any analysis of its aquatic bird diversity should compare different levels (α and β) with the γ diversity of the landscape. Habitat heterogeneity may affect the structure and composition of these species assemblages, yet this subject has been little studied in Chile. The objective...
The diet of Puma concolor was seasonally surveyed in Predio Rucamanque, Araucanía, in southern Chile.
