Energy Landscapes Shape Animal Movement Ecology
The metabolic costs of animal movement have been studied extensively under laboratory conditions, although frequently these are a poor approximation of the costs of operating in the natural,Expand

Dealing with non-native species: what makes the difference in South America?
Non-native species have reached South American ecosystems and may be threatening the exceptional biodiversity of this region. However, people often value and exploit introduced species not knowingExpand

How are garbage dumps impacting vertebrate demography, health, and conservation?
Abstract Organic waste can be considered a food subsidy which represents an important source of energy for different species that exploit it. However, it could produce contrasting impacts, bothExpand

Spatial and temporal patterns in the diet of the Andean condor: ecological replacement of native fauna by exotic species
The development of conservation strategies to protect viable populations of scavenging birds requires the existence of adequate and safe food supplies in the wild. Early reports on Andean condorsExpand

How do roads affect the habitat use of an assemblage of scavenging raptors?
Scavengers may benefit from the availability of dead animals along roads that result from collisions with vehicles. However, roads are also considered risky places for many species. Animal habitatExpand

Energy Beyond Food: Foraging Theory Informs Time Spent in Thermals by a Large Soaring Bird
Current understanding of how animals search for and exploit food resources is based on microeconomic models. Although widely used to examine feeding, such constructs should inform otherExpand

Size and spatio-temporal variations of the Andean condor Vultur gryphus population in north-west Patagonia, Argentina: communal roosts and conservation
Abstract Estimations of the population sizes of threatened species are fundamental for conservation. The current estimate of the population of the Andean condor Vultur gryphus is based on limitedExpand

Can accelerometry be used to distinguish between flight types in soaring birds?
BackgroundAccelerometry has been used to identify behaviours through the quantification of body posture and motion for a range of species moving in different media. This technique has not beenExpand

Sexual-size dimorphism modulates the trade-off between exploiting food and wind resources in a large avian scavenger
Animals are expected to synchronize activity routines with the temporal patterns at which resources appear in nature. Accordingly, species that depend on resources showing temporally mismatchedExpand

Breeding behavior of a pair of free‐living Andean Condors
The breeding behavior of Andean Condors (Vultur gryphus) is known primarily from observations of captive pairs. This species is the only sexually dimorphic one in its family (Cathartidae), permittingExpand
