“…CHIARELLO et al (1997) reported the nocturnal activity pattern and habitat use, and recently, SOUTO-LIMA et al (2009) presented substantial data on the diet of this species. There is currently a management program for this species financed by the Brazilian government, including genetic studies (OLIVEIRA et al 2007).…”

ABSTRACT. The thin-spined porcupine Chaetomys subspinosus (Olfers, 1818) is a species endemic to the extremely disturbed and fragmented Brazilian Atlantic forest. Little is known about its natural history. We analyzed the preferences of porcupine diurnal roost and home range, based on one relocated adult male that was radio-monitored during 1999.The individual was captured in the urban zone of Santa Teresa, Brazil, and relocated to a forest reserve 6 km from the capture site. The thin-spined porcupine feeds only on leaves. It prefers intermediate forest stratum (6-15 m of height) for roosting during daytime, generally using inclined branches with a diameter of 2 to 5 cm. Most observations indicated a prehensile tail position. Home range was relatively large (15.81 ha) for an arboreal animal of this size and new areas were still being explored after five months of monitoring.

“…This medium-sized (1.3-2.7 kg) rodent species (Chiarello et al 1997;Oliveira et al 2012) is nocturnal, arboreal and folivorous (De Souto Lima et al 2010;Giné et al 2010;Giné et al 2012;Oliveira et al 2012). It is also opportunistically hunted by local people mainly for the meat (Castilho et al 2013).…”

Microscopy and development of a remarkable pitted quill from the thin-spined porcupine,Chaetomyssubspinosus

Scanning electron microscopy shows that the quill surface from the thin-spined porcupine (Chaetomys subspinosus (Olfers, 1818)) has several regional cuticular patterns of which the most expansive is highly pitted with 4 μm wide pores leading to pits, which in turn communicate circumferentially via tunnels to neighboring pits. The cell unit of the pitted layer is a hexagonal or pentagonal prism, the “pitted fibrillous cuticular cell” (PFCC), which has a superficial pitted cuticular scale derived part with an underlying part packed with fine fibrils and the nucleus. The scaled part has about six scales, which swell and fuse except where raised cuticular scales from the inner root sheath intervene. This unique and complicated cell soon dies even while below the skin’s surface during its development. The raised scale-bearing cells of the inner root sheath leave their imprints on the PFCC’s surface, thus indicating that the quill’s pitted layer is at one time soft. Histochemistry, energy dispersive X-ray spectrometry, and Fourier transform infrared spectrometry show that the PFCC is keratinous.

“…These animals are arboreal, nocturnal, and solitary [10][11], passing unnoticed by most casual observers [10][11]. Their diet is strictly leaves [10,[12][13][14]. They inhabit mature and secondary forests, occasionally shaded cocoa plantations [6], but prefer patches of native forest with high vertical complexity, such as forest edges [15].…”

The thin-spined porcupine, Chaetomys subspinosus, is an endemic mammal of the Atlantic forest of northeastern Brazil. With its population declining, it has been listed as "vulnerable" in the Brazilian Red List. Its National Action Plan, published in 2011, intended to develop awareness projects about the species in local communities, to implement alternative income projects and protein consumption, and to evaluate hunting pressure. This study investigates rural residents' knowledge of the thin-spined porcupine and its uses within two protected areas. We also examine residents' behaviour and perceptions about wildlife conservation. One hundred twenty-five semi-structured interviews were conducted with rural residents of the Una Wildlife Refuge and the Serra do Conduru State Park. Local knowledge was higher among males with lower levels of formal education who were current or past hunters. Negative behaviour occurs among residents in both protected areas. There is a need for greater control of potential threats such as hunting, use of fire and deforestation, which are inconsistent with the existence of protected areas and conservation of the thin-spined porcupine. Information provided by this study can improve and promote actions within the National Action Plan for the conservation of C. subspinosus.Key words: Human Behaviour; Hunting; Local people; Perception of rural residents; Thin-spined porcupine. ResumoO ouriço-preto, Chaetomys subspinosus, é um mamífero endêmico da Mata Atlântica do nordeste brasileiro. Devido ao declínio populacional da espécie, ele tem sido listado como "vulnerável" pela IUCN. O Plano de Ação Nacional da espécie foi publicado em 2011 e tem como objetivos desenvolver projetos de conscientização sobre a espécie, implementar projetos de renda alternativa e fonte de proteína alimentar e avaliar a pressão da caça. Esse estudo investiga o conhecimento de moradores rurais sobre o ouriço-preto e seus usos em áreas protegidas. O comportamento e percepções dos moradores com relação à conservação da fauna também foram investigados. Foram conduzidas 125 entrevistas semi-estruturadas com moradores rurais do Refúgio de Vida Silvestre de Una e do Parque Estadual Serra do Conduru. O conhecimento local sobre a espécie foi maior em homens com pouca escolaridade e que estavam envolvidos com a atividade de caça. Comportamentos negativos são realizados pelas pessoas em ambas as áreas. É necessário que haja um maior controle sobre as potenciais ameaças a espécie como caça, uso do fogo e desmatamento, pois tais práticas são inconsistentes com a existência das áreas protegidas e com a conservação do ouriço-preto. As informações fornecidas por esse estudo visam melhorar e direcionar as ações do Plano de Ação Nacional para conservação da espécie.
