Medium and Large-sized Mammals in a Private Reserve of Natural Heritage in the Municipality of Jaú, São Paulo, Brazil

Abstract

flora sureveys are fundamental for the implementation of management plans and measures for the conservation of the biome. The Amadeu Botelho Ecological Reserve (ERAB) is a Private Reserve of Natural Heritage (PRNH) that contains a preserved fragment of Atlantic Forest whose mammal fauna has yet to be thoroughly studied. Hence, the present study surveyed the mammalian fauna of the ERAB and evaluated the influence of the farm's plantations and its proximity to the urban center on these mammals. Materials and Methods Study site The study area is the Ecological Reserve Amadeu Botelho (ERAB), one Private Reserve of Natural Heritage (PRNH) created through the Ordinance No. 19 ICMBio (Instituto Chico Mendes de Conservação da Biodiversidade) in 2000. It is owned by the Santo Antonio Ipês farm located in the municipality of Jaú (22°18′ S, 48°31′ W), in the central-western region of the state of São Paulo, in southeastern Brazil. The farm was acquired by Arruda Botelho family in the late 19th century (Conselho Nacional da Reserva da Biosfera da Mata Atlântica 2008). The farm grows various crops such as sugarcane, corn, sunflowers, oranges, as well as species of the genus Cordia, medicinal passion fruit, peaches and coffee. These plantations surround the entire forest fragment, giving it a clear cut and elongated appearance (Figure 1). Several dirt roads cut through these plantations, which are used to transport harvested crops. In addition, two roads cut

Short and Narrow Roads Cause Substantial Impacts on Wildlife

“…The roadkilled native species represented ~56% of all medium-and large-sized mammals that are known to occur in the study area (N = 16; Bovo et al 2018). The most frequently roadkilled species -D. novemcinctus, N. nasua, H. hydrochaeris, D. albiventris and C. spinosus -are commonly recorded in HMLs (Dotta & Verdade 2011, Reale et al 2014Magioli et al 2016), and in other road ecology studies (Coelho et al 2008, Cáceres et al 2010, Dornas et al 2012, Huijser et al 2013. Species such as C. spinosus, D. novemcinctus and H. hydrochaeris are known to thrive in agricultural areas (Magioli et al 2014b), and are very common, apparently with abundant populations, which can explain the high roadkill numbers.…”

“…However, C. thous, a common species in HMLs (Ferraz et al 2010) and frequently roadkilled (Coelho et al 2008, Cáceres et al 2010, Cáceres et al 2012, Dornas et al 2012, Bueno et al 2013, Huijser et al 2013, was recorded only once in our study. Species such as Galictis cuja (Carnivora, Mustelidae) and Lontra longicaudis (Carnivora, Mustelidae), can be expected to be present in HMLs (Reale et al 2014, Magioli et al 2016, but they only occur in low densities, similar to other carnivore species (Cardillo et al 2004, Ripple et al 2014, Grilo et al 2015. For such species, the loss of a single individual may have severe consequences for their population (Srbek-Araújo et al 2015).…”

Connectivity maintain mammal assemblages functional diversity within agricultural and fragmented landscapes

“…These environments represent not only essential refuges for the fauna but also important providers of ecosystem services at the landscape level. Studies conducted over the last 15 years in agricultural and fragmented landscapes in the Atlantic Forest and Cerrado show evidence of the presence of important and threatened mammal species (Chiarello 2000a;Rocha and Dalponte 2006;Dotta and Verdade 2007;Silva and Pontes 2008;Eduardo and Passamani 2009;Bruna et al 2010;Lessa et al 2012;Hannibal 2014;Magioli et al 2014a;Reale et al 2014;Estrela et al 2015) such as large predators (Puma concolor, Leopardus pardalis, and Chrysocyon brachyurus), large herbivores (Mazama sp. ), and seed dispersers (Dasyprocta sp., Cuniculus paca, Pecari tajacu).…”

A preliminary survey of medium and large‐sized mammals from Lebu Natural Protected Forest, Southwest Showa, Ethiopia

“…Mammals are the most diverse and successful group of animals having approximately 5,416 extant species on the globe (Geleta & Bekele, 2016;Reale, Fonseca, & Uieda, 2014). About 320 species of mammals exist in Ethiopia of which 55 are endemic (Lavrenchenko & Bekele, 2017).…”
