Pampas fox (Lycalopex gymnocercus) new intermediate host of Sarcocystis svanai (Apicomplexa: Sarcocystidae)
(Elsevier, 2017-01)Several Sarcocystis spp. have carnivores as definitive host and sarcocysts are common in muscles of herbivores (intermediate host). However, sarcocysts have been found in muscles of wild and domestic carnivores suggesting ... -
Niche Overlap Determination Through Habitat Suitability Models: A Management Tool for Native Birds of the Argentinean Pampas
(BioOne, 2018-01)In Argentina, predominantly in the Pampas ecoregion, the natural rangelands have increasingly been replaced by crops. Avifaunal studies have shown that the population density of several species decreased as the proportion ... -

(BioOne, 2018-03)Sheldgeese [Upland Goose (Chloephaga picta picta), Ashy-headed Goose (C. poliocephala) and Ruddyheaded Goose (C. rubidiceps)] have similar migratory patterns, breeding in Patagonia (Argentina and Chile) and wintering mainly ... -
Migration Routes and Stopover Sites of Upland Geese Chloephaga Picta in South America
(SAGE Publications, 2018-05-01)The Upland Goose (Chloephaga picta picta) is a migratory species of South America, which breeds from September to April in Patagonia (Argentina and Chile) and winters from May to September in the southern Pampas (Argentina). ... -
Weather conditions affect spring migration departure of Ruddy-headed Goose in the southern Pampas, Argentina
(Taylor and Francis, 2022-07)The Ruddy-headed Goose (Chloephaga rubidiceps) has two separate populations: one sedentary, which resides in the Falkland/Malvinas Islands and one migratory that overwinters mainly in the Pampas region (Argentina) and ... -
First assessment on the influence of wind farms and high-voltage networks on ruddy-headed goose Chloephaga rubidiceps migration in Patagonia, Argentina
(Springer, 2023-07)Ruddy-headed goose Chloephaga rubidiceps has a migratory population that overwinters mainly in the Pampas region, Argentina, and breeds in Southern Patagonia. This population has decreased considerably, with less than 800 ... -
Pampas fox spatial and temporal variation in Argentinean agroecosystems
(CSIRO Publishing, 2024)Context: Agricultural activities have reduced wildlife natural habitats and increased the spatial overlap between animals' distribution and human activities. However, carnivores with a broad diet and flexible habitat ... -
Farmers’ perceptions of wildlife in agroecosystems: Insights from a highly modified area of the Pampas region, Argentina
(Elsevier, 2024-09)People’s perceptions of wildlife are influenced by various factors. Studying these factors is a valuable tool to help conserve agro-biodiversity. The objective of this study was to analyze farmers’ perception of birds and ... -
