Abstract Context. The conservation of large wild herbivores presents a challenge posed by the fact that their broad habitat requirements overlap with various human activities. Elucidating the factors that explain their distribution patterns provides us with a better understanding of habitat–species relationships and facilitates the design of effective management policies. Aims. Identify the natural (forage availability, weather) and anthropogenic (hunting, interspecific competition) factors…

Where are the males? The influence of bottom-up and top-down factors and sociability on the spatial distribution of a territorial ungulate

The factors that regulate the abundance and distribution of wild herbivores are key components of a species’ ecology and include bottom-up and top-down mechanisms, as well as aspects related to



Spatial and Seasonal Dynamic of Abundance and Distribution of Guanaco and Livestock: Insights from Using Density Surface and Null Models

A marked seasonal pattern in abundance and spatial distribution of L. guanicoe and small-livestock was found, suggesting a competition mechanism between ecologically similar herbivores, although various environmental factors could also contribute to habitat segregation.

Spatial abundance models and seasonal distribution for guanaco (Lama guanicoe) in central Tierra del Fuego, Argentina

The results confirm that part of the guanaco population performs seasonal migratory movements and that the main valleys present important wintering habitats for guanacos as well as up-hill zones during summer.

Habitat use and preference by guanacos, vicuñas, and livestock in an altitudinal gradient in northwest Argentina

Distribution of ungulates is regulated by natural factors, such as presence of other species, climate, and habitat variability, as well as human activities, including livestock grazing and mining.

Large-herbivore distribution and abundance: intra-and interspecific niche variation in the tropics

The results suggest that interspecific competition between antilopine wallaroos and eastern grey kangaroos may occur and the effects of changing climatic conditions on fire regimes, habitat structure, and water availability may lead to species declines and marked changes in macropod communities.

Spatial distribution and habitat selection in coexisting species of mountain ungulates

It is underscore that joint approaches of spatial and ecological processes are necessary to disclose the type of interaction at play within a community, and which environmental factors led to species being aggregated or segregated.

Effects of livestock on guanaco Lama guanicoe density, movements and habitat selection in a forest–grassland mosaic in Tierra del Fuego, Chile

Abstract Locally abundant ungulates often come into conflict with human activities. After a population collapse that reached its nadir in the 1970s, the guanaco Lama guanicoe population in Tierra del

Habitat selection by reintroduced guanacos (Lama guanicoe) in a heterogeneous mountain rangeland of central Argentina

Quebrada del Condorito National Park is located in the upper belt of the mountains of central Argentina and preserves a heterogeneous rangeland area. After the creation of the National Park, in 1996,

Change of niche in guanaco (Lama guanicoe): the effects of climate change on habitat suitability and lineage conservatism in Chile

The limitations of this taxon as it experiences forces imposed by climate change dynamics are described and a grim outlook of the future potential distribution of guanaco in Chile is provided.
