rodents, such as paca (Cuniculus paca), agouti (Dasyprocta sp.) and other wild mammals, serve as animal protein sources for local rural communities (Valsecchi, El Bizri, & Figueira, 2014; Van Vliet et al., 2015), which usually leads to overhunting in the Amazon.
The guinea pig (Cavia porcellus, Caviidae, Linnaeus, 1758) is a hystricomorph
rodent, widely used as animal model for research development, especially that related to placentation (Miglino et al., 2004; Mess, 2007) and development of embryonic membranes (Oliveira et al., 2012; Vasconcelos et al., 2013), which have been studied by members of our research group.
A new species of whipworm from a South American hystricomorph
Mountain lion predation may be higher in CSP compared to Yellowstone National Park (Barnowe-Meyer et al., 2009) because the mountain lion population in the Black Hills is restricted to a relatively small island of forested habitat, the, predators do not compete with other apex predators such as wolves or grizzly bear, and there is a diverse prey assemblage consisting of white-tailed deer, mule deer, elk, bighorn sheep, mountain goat (Oreamnos americanus), and pronghorn as well as smaller prey including porcupine (Hystricomorph
hystricidae) and wild turkey (Meleagris gallopavo) available to predators.
Nutria (Myocastor coypus) are large hystricomorph
South American rodents adapted to semi-aquatic environments (Gosling 1981).
The capybara (Hydrochoerus hydrochaeris Linnaeus, 1766) is a large semi-aquatic polygynous New World hystricomorph
rodent (Macdonald, 2006; Oliveira and Bonvicino, 2006).
On the external characters of some Hystricomorph
We have observed that the progesterone values reported here were similar to many hystricomorph
rodents, as reported previously for the Cavia porcellus (Croix & Franchimont 1975), Hystrix africaeaustralis (Van Aarde 1985) and Agouti paca (Montes & Baz 2006).
The coypu or nutria Myocastor coypus (Molina, 1782; Rodentia, Myocastoridae) is an hystricomorph
rodent native to southern South America (Parera, 2002).
