Here we report the occurrence of Ancylostoma (Ancylostoma) buckleyi (Le Roux and Biocca, 1957) (Nematoda: Ancylostomatidae) in the small intestine of Pampas foxes (Lycalopex gymnocercus) (Mammalia: Canidae). This fox is the most abundant native carnivore in southern South America, where it inhabits grasslands, open woodlands and areas highly modified by extensive ranching and agricultural activ...

We monitored the number of caiman (Caiman crocodilus yacare) nests in two ranches in the Brazilian Pantanal that cover an area of about 50.000 ha for 28 years (1987-2014). The number of nests was related to combinations of rainfall, water level, and number of days with temperature below 20°C, depending on the area. Most of the variation in number of nests could not be predicted by the environme...

Abstract Wildfires have increased in protected areas (PAs) of the Colombian Amazon following 2016 peace agreement between Government and Revolutionary Armed Forced Colombia (FARC—Spanish acronym). Recent study efforts to understand this issue suffer from data scarcity limited consultation local stakeholder perspectives on factors affecting wildfires. This uses a social–ecological systems framew...

Interbreeding between wild fish and escaped farmed fish (or deliberate releases in enhancement/ranching) could result in genetic changes in the wild populations that reduce overall fitness and productivity (Utter et al. 1993; Utter 1998). Although this problem has been discussed for a long time (e.g. Hindar et al. 1990; Skaala et al. 1990) experimental evidence of harmful effects from interbree...

Biologists are nearly unanimous in their belief that humanity is in the process of extirpating a significant portion of the earth's species. The ways in which we are doing so reflect the magnitude and scale of human enterprise. Everything from highway construction to cattle ranching to leaky bait buckets has been implicated in the demise or endangerment of particular species. According to Wilso...

Abstract We investigate how historical patterns of primary production influenced development across local economies in Argentina. Our identification strategy exploits exogenous variation the composition induced by climatic features. find that locations specializing ranching had weaker linkages with other activities, higher concentration land ownership, lower population density, and less immigra...
