Species displaced outside their native range may face new pressures resulting from both environmental gradients and important differences in ecosystem structure. We investigated how this may impact the morphological variation of a globally introduced carnivoran, the small Indian mongoose. Previous research showed size variations in several introduc...

The small Indian mongoose has been introduced into several important hotspots of biodiversity and is considered the wild carnivore with the greatest negative impact on autochthonous ecosystems. Understanding the introduction and dispersal history of the species is crucial in any effort to conserve global biodiversity. We investigated the genetic st...

The introduction of exotic species is one of the major causes of the decline of global biodiversity. Tropical insular ecosystems, including many biodiversity hotspots, are particularly threatened by biological invasions. Two wild carnivores have been introduced in the Caribbean, the northern raccoon Procyon lotor and the small Indian mongoose Urva...

Invasive species are considered as one of the major threats to biodiversity and represent a major challenge in the conservation of natural ecosystems, in preventing damage to agricultural production, and human health risks. Environmental Niche Modelling has emerged as a powerful tool to predict the patterns of range expansion of non-native species...

Theoretical models predict that spatial sorting at the range edge of expanding populations should favor individuals with increased mobility relative to individuals at the center of the range. Despite the fact that empirical evidence for the evolution of locomotor performance at the range edge is rare, data on cane toads support this model. However,...

Raccoons are American carnivores, considered invasive across several countries worldwide, especially in Europe. In the Iberian Peninsula, previous studies on raccoons documented several breeding populations in Spain a decade ago and only two confirmed records from isolated individuals in Portugal. Given the need for updating its Iberian distributio...

La famille des mangoustes compte 34 espèces, présentes en Afrique et en Asie dans des habitats très variés, de la savane à la forêt tropicale. De la structure sociale complexe des suricates et des mangues rayées, à la vie solitaire des mangoustes à queue courte, cette famille de petits carnivores réserve bien des surprises.

Invasive alien species represent one of the major factors of global loss of biodiversity and disruption of natural ecosystems. The small Indian mongoose, Urva auropunctata, is considered one of the wild carnivore species with the greatest negative impact on global biodiversity. Understanding of the factors underpinning the species’ distribution and...

The introduction of species outside their natural range is one of the major threats to biodiversity and has often been identified as a menace to agricultural production and human health. The raccoon is recognized as a globally invasive species. However, several populations in the Caribbean were long considered native and endemic species. Although p...

Temperature is a critical abiotic factor impacting all aspects of the biology of organisms, especially in ectotherms. As such, it is an important determinant of the potential invasive ability of organisms and may limit population expansion unless organisms can physiologically respond to changes in temperature either through plasticity or by adaptin...

Empirical and theoretical studies have investigated the trade-offs between reproduction, dispersal and/or survival that may arise between individuals at the range edge of an expanding population. The differential allocation of resources to these life-history traits may then be constrained by the metabolism of an individual. Previous studies of an i...
