The effects of deforestation on wildlife along the transamazon highway

Abstract

Hunting, although prohibited, is widely practiced by the rural inhabitants settled along the Transamazon highway. In 1997 and 2000, we investigated subsistence hunting in Uruara´, a township located on an Amazonian pioneer front (Brazil). We analyze hunting practices, game yield, hunting efficiency and their relation to forest coverage rate. The hunting methods were stand hunting (55.5%) and beating (44.5%). Paca (Agouti paca), tatus (Dasypus novemcinctus and D. septemcinctus), and collared peccary (Pecari tajacu) were the most frequently hunted species, supplying 68% of the gross game weight. Beating was significantly more efficient than stand hunting (3 vs. 1.9 kg/hunter/h, Mann-Whitney U test, P=0.02). Hunting territories were classified in three categories according to forest coverage rate. The higher the forest coverage rate the larger was the harvested species and the more efficient the hunter (Kruskal-Wallis test P=0.01). Considering the ecological and demographic changes in this pioneer settlement, development of a viable plan for game management and forest preservation is of great importance.

Ride, shoot, and call: wildlife use among contemporary urban hunters in Três Fronteiras, Brazilian Amazon

“…Most of the Amazon Basin's forests are inhabited by indigenous people (Schwartzman et al 2000, Nepstad et al 2006) who rapidly join the global marketplace and are able to acquire modern weapons and tools (guns, steel tools, fishing gear, chainsaws) and motorized transport. As a result, scientific research on bushmeat in the Amazon has focused on assessing hunting practices and their effects on biodiversity conservation (Ayres and Ayres 1979, Bodmer et al 1997, Emídio-Silva 1998, Lopes and Ferrari 2000, Peres 2001, Zapata-Ríos 2001, Bonaudo et al 2005, da Silva et al 2005, Levi et al 2009, Parry et al 2009, Prado et al 2012, Shepard et al 2012. There has been a limited number of studies dealing with the economics and social underpinnings of Amazonian hunting (Read et al 2010, Iwamura et al 2014.…”

Monitoramento do ciclo estral de cutias (Dasyprocta leporina Lichtenstein, 1823) através de citologia esfoliativa vaginal e ultrassonografia

“…No semiárido nordestino, esses animais são bem adaptados às características climáticas (Ribeiro et al 2008), assim, apresentam um grande potencial zootécnico, devendo--se, para tanto, direcionar um maior fluxo de pesquisas, no intuito de garantir sua conservação (Souza et al 2003) e a formação de criatórios com fins comerciais (Bonaudo et al 2005). Nos últimos anos, diversos conhecimentos têm sido gerados no tocante à biologia reprodutiva das cutias, como a caracterização morfológica dos ovários (Almeida et al 2003), tubas uterinas (Fortes et al 2005), placentação (Rodrigues et al 2003) e criopreservação de folículos pré-antrais (Wanderley et al 2012) em D. leporina, bem como o diagnóstico de gestação por ultrassonografia em D. prymnolopha (Sousa et al 2012).…”

“…Animals such as the paca Cuniculus paca, the agouti Dasyprocta sp., the capybara Hydrochoerus hydrochaeris, the armadillo Dasypus sp., the collared peccary Pecari tajacu, the white-lipped peccary Tayassu pecari and the brocket deer Mazama sp. are much used in subsistence hunting in rural areas of the Brazilian Amazon Region (Bonaudo et al, 2005).…”
