Is the native deer Mazama gouazoubira threatened by competition for food with the exotic hare Lepus europaeus in the degraded Chaco in Córdoba, Argentina?

Feeding Ecology of Five Neotropical Ungulates: A Critical Review

“…These studies were conducted in rural communities in the Amazon where the species is often abundant and widely hunted, thereby facilitating access to butchered stomachs for analysis (Branan et al 1985, Bisbal 1994, Bodmer 1991b, Gayot et al 2004. Studies of the grey brocket deer mostly relied on stomach content analyses (used in 55% of the records) (Stallings 1984, Branan et al 1985, Bodmer 1991b, Bisbal 1994, Gayot et al 2004, followed by fecal analyses (33%) (Kufner et al 2008, Pinder 2004, Serbent et al 2011) and direct observation (22%) (Richard et al 1995, Richard & Juliá 2001. Overall, for the five ungulates, the analysis of fecal or stomach samples was the most common type of analysis (Figure 1).…”

“…The size of the study areas varied from 200 ha to 1,523,400 ha. The size of the effective sampling area within the study area (area where feces and stomachs were searched and foraging direct obervations were performed) was only reported in five diet records (10%) (Salas & Fuller 1996, Fragoso & Huffman 2000, Kufner et al 2008, Talamoni & Assis 2009, Serbent et al 2011 ). In addition, only nine records (17%) specified the number of sampling sites per ecological unit on the landscape studied (Eddy 1961, Salas & Fuller 1996, Henry et al 2000, Santos et al 2005, Kufner et al 2008, Talamoni & Assis 2009, Serbent et al 2011, Hibert et al 2011, Barcelos et al 2013.…”

Only six records (11%) indicated the stage of regeneration of the forest in which the study occurred (Richard et al 1995, Fragoso & Huffman 2000, Richard & Juliá 2001, Gayot et al 2004, Hibert et al 2011, Barcelos et al 2013 (Table 1).…”

Mammalia, Lagomorpha, Leporidae, Lepus europaeus, Pallas, 1778: distribution extension, first confirmed record for Paraguay

“…Most mention L. europaeus as a food item in carnivore diet studies (Jaksic et al1983;Branch et al 1996;Pia et al 2003;Diuk-Waser and Cassini 1998;Zapata et al 1998;Rau and Jiménez 2002;Donadio et al 2004;García and Kittlein 2004;and Zapata et al 2005), avian scavenger diet studies , in occasional records from faunal surveys (Aguilar et al, 2007;Cossio 2004;Dotta and Verdade 2007;and Aguiar et al 2007) and/or in describing the ecology of Lepus itself (Auricchio et al 1999;Campos et al 2001;Cossíos, 2004;and Kufner et al 2008).…”

Ocupação de paisagens dentro e fora de unidades de conservação pelo veado-catingueiro (Mazama gouazoubira Fischer, 1814) no nordeste paulista

“…Esta espécie pode ser considerada um cervídeo de pequeno porte, com altura média de 58 cm e peso entre 11-25 kg, sendo que os machos apresentam chifres simples (Black-Décima et al 2010). Os poucos estudos disponíveis com o veadocatingueiro têm reportado uma dieta não-seletiva, sendo considerado um frugívoro generalista, reduzindo assim sua competição por alimento com outras espécies (Gayot et al 2004;Kufner et al 2008). No Brasil, está presente em todos os biomas, exceto na Amazônia.…”
