“…The roads lead to deforestation, a decrease in patch size and an increase in the edge effect, and also causes problems with roadkill and urban expansion (Bager & Fontoura, 2013;Barber, Cochrane, Souza, & Laurance, 2014;Mello, Toppa, & Abessa, 2011). Thus, it is a serious problem for many protected areas which are bordered or cut by roads (Barber et al, 2014;Diniz & Brito, 2015;Marcantonio, Rocchini, Geri, Bacaro, & Amici, 2013;Moraes et al, 2017).…”

Tropical forests are threatened due to forest clearing and fragmentation which lead to a decrease in forest cover area and landscape connectivity, while also increasing edge effects. These impacts affect biodiversity and ecosystem service provision which are essential for humanity's well-being. Protected areas are created to minimize these effects on biodiversity, but many of them are threatened due to forest fragmentation in the surrounding areas. Thus, forest restoration is needed to ensure the suitability of protected areas in the landscape. However, restoration planning needs to adopt an ecological landscape approach to ensure the recovery of the biodiversity and the ecological processes. This study developed a forest sustainability index (FSI) which represents the forest patch potential in facilitating landscape restoration in a protected area and its surroundings. A land-use/land-cover map was used to calculate landscape metrics at two levels: landscape and patch. Landscape metrics were subsequently selected to create the index. The tested landscape presents a great number of fragments with most of them being small in size and having irregular shapes. The focus areas for forest restoration are located close to forest fragments with higher FSI values, as these can facilitate natural restoration and guarantee the maintenance of the ecosystem processes.

“…Unfortunately, only 0.5% of the Cerrado is protected (Durigan et al 2007). The remnants left in the Cerrado, both in and outside of the protected areas, are required to maintain local biodiversity (Diniz & Brito 2015;Françoso et al 2015).…”

2017) Movement patterns and space use of the first giant anteater (Myrmecophagatridactyla) monitored in São Paulo State, Brazil, Studies on Neotropical Fauna and Environment, 52:1, 68-74, ABSTRACTThis study analyzes a giant anteater's (Myrmecophaga tridactyla) movement patterns and space use in São Paulo, Brazil. It is the first study to track a giant anteater with Iridium-GPS. The anteater traveled an average distance of 1326 m day -1 with an average speed of 1.04 m min -1 . Home range by Kernel was 2.46 km 2 while the core area was 0.75 km 2 , and estimates by Brownian bridge and minimum convex polygon were also provided. The anteater used shrub savanna, open savanna, and water habitats more than expected. Monitoring ended just after 10 days when the female giant anteater's GPS was found on an illegal trail. RESUMOEste estudo analisa os padrões de movimento e o uso do espaço por um tamanduá-bandeira (Myrmecophaga tridactyla) em São Paulo, Brasil. É o primeiro estudo a monitorar um tamanduábandeira com GPS-Iridium. O tamanduá-bandeira percorreu uma distância média de 1.326 m/dia com uma velocidade média de 1,04 m min -1 . A área de vida estimada por Kernel foi de 2,46 km 2 , enquanto a área núcleo foi de 0,75 km 2 . Estimativas por Ponte Browniana e Mínimo Polígono Convexo também foram fornecidas. O tamanduá-bandeira utilizou os hábitats savana arbustiva e aberta, e àqueles relacionados à água mais do que o esperado. O monitoramento terminou depois de 10 dias quando o GPS do tamanduá-bandeira foi encontrado caído em uma trilha ilegal. ARTICLE HISTORY

“…The situation is even more dire for M. tridactyla. According to Diniz & Brito (2015), roadkill is a serious threat to M. tridactyla persistence, and the removal of just a few individuals may increase the possibility of population extinction.…”

“…However, roadkill could provide important insights into the status of both threatened and not threatened species (IUCN, 2017). For example, Diniz & Brito (2015) estimated that roadkill The present work is a case study based on a literature review of studies about roadkills in the Cerrado. Our goal was to assess the risk of this anthropic disturbance to the superorder Xenarthra.…”

The Brazilian Cerrado possesses a great diversity of xenarthrans with 12 species: eight armadillos, three anteaters, and one sloth. Even though several of these species are threatened, roadkill is considered a major threat only to Bradypus variegatus and a justification for listing Myrmecophaga tridactyla as Vulnerable. Here we present evidence that roadkill is a risk factor for xenarthran persistence, even to non-threatened species. To assess roadkill impact, we compiled articles related to mammal roadkill in the Brazilian Cerrado. One or more species of Xenarthra were among the top five most common roadkilled species in over 90% of the studies. The group represented over 50% of the recorded mammals in 33.3% of the papers and more than 40% in 66.6% of them. In 33.3% of the papers Pilosa contributed over 25% of the records and Cingulata presented the same proportion in 44.4% of them. This study reinforces the idea that roadkill must be considered a major threat to xenarthran populations in conservation status assessments. Therefore, we suggest that mitigation measures be implemented, and that the IUCN take into account that roadkill is one of the greatest threats to populations of xenarthrans.
