Landscape correlates of the distribution of coypuMyocastor coypus(Rodentia, Mammalia) in Argentinean Pampas

Abstract: The coypu is a rodent indigenous to aquatic habitats in southern South America, which is considered a pest where it has been introduced and a valuable furbearer resource within its native range. The objective of this study was to identify the main landscape correlates of coypu distribution in the Pampas. Previous studies provided two non-exclusive hypotheses: (1) if hunting pressure regulates coypu distribution, then coypu presence should decrease in areas with high human density, while (2) if resource availab… Show more

“…The families Hydrochaeridae and Myocastoridae have evolved under other conditions. These two clades have a large geographic distribution (Mares and Ojeda,1982) including both Patagonian and Brazilian subregions, but their semiaquatic habits confine them to wetter biomes and mostly semiaquatic and softer food sources, for example, sprouting grass (Guichón et al,2003; Desbiez et al,2011; Leggieri et al,2011). Although they have a highly oblique chewing direction and powerful incisors, the semiaquatic coypu have not really specialized to an abrasive diet and still possess a high EI value (Martin,1993; Vassallo and Verzi,2001).…”

“…In northeast France, coypus and muskrats are commonly observed in various riparian habitats, and their occurrence appears to be independent of watercourse width, bank height or bank slope [41]. In its native South American distribution range, coypus are less frequent in urban and semi-urban landscapes, with denser populations in wetlands surrounded by grasslands [42,43]. Although muskrats in their native North American distribution range are more likely to occur in areas with large lakes and high amounts of forage biomass [44], where they affect plant communities [45], the occurrence of invasive muskrats in Sweden was successfully predicted by the percentage cover of swamps, meadows and lakeshore meadows [46].…”

“…Los coipos habitan en arroyos de movimiento lento, lagos, pantanos de agua dulce y agua salobre. Su densidad en las pampas argentinas se asoció positivamente con el ancho de la llanura aluvial de los cursos de agua y los usos agrícolas de la tierra, y negativamente con la urbanización y los paisajes semiurbanos (Leggieri et al 2011).…”
