Heavy metals in northern Chilean rivers: spatial variation and temporal trends.
Rivers of central-northern Chile are exposed to pollution from different sources, including mining activities, natural orogenic process, volcanic activity, and geology. In order to determine theExpand

Multivariate heredity of melanin-based coloration, body mass and immunity
The genetic covariation among different traits may cause the appearance of correlated response to selection on multivariate phenotypes. Genes responsible for the expression of melanin-based colorExpand

Arrival date, age and breeding success in white stork Ciconia ciconia
Early arrival to breeding grounds is a life history trait in birds that can result in fitness benefits. We studied the relationship between arrival date and breeding success of individuals in aExpand

Kestrel-Prey Dynamic in a Mediterranean Region: The Effect of Generalist Predation and Climatic Factors
Background Most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly in boreal ecosystems. In such regions, manyExpand

Environmental heterogeneity influences the reliability of secondary sexual traits as condition indicators
Numerous studies have shown positive associations between ornaments and condition, as predicted by indicator models of sexual selection. However, this idea is continuously challenged by oppositeExpand

Avian responses to fragmentation of the Maulino Forest in central Chile
Depending on the mosaic of habitats that is created, forest fragmentation can reduce the abundance and diversity of forest birds. Temperate deciduous forests in South America are rapidly beingExpand

Age and breeding success related to nest position in a White stork Ciconia ciconia colony
Coloniality is a breeding system that may produce benefits in terms of breeding success, although these advantages could vary according to factors such as colony size or nest position. We studiedExpand

Native forest replacement by exotic plantations triggers changes in prey selection of mesocarnivores
ABSTRACT Replacement of native forests by forest plantations may change the composition and abundance of small mammals, thus influencing the foraging behavior of mesocarnivores in these human-createdExpand

The condition dependence of a secondary sexual trait is stronger under high parasite infection level
Indicator models of sexual selection predict that the expression of sexual ornaments should be condition dependent. This is only partly supported by data, as many studies do not find positiveExpand

Nest‐site fidelity and breeding success in White Stork Ciconia ciconia
Nest-site fidelity is a life-history trait of birds that may produce benefits in terms of fitness. We studied the relationship between breeding success and nest fidelity in the White Stork CiconiaExpand
