“…additionally, C. prehensilis may occupy a different trophic niche than other porcupines. Whereas field studies of Chaetomys subspinosus and Coendou spinosus suggest that these species are almost exclusively folivorous (Giné et al, 2010;lima et al, 2010;Passamani, 2010), direct observations of feeding behavior by C. prehensilis suggests that this species feeds primarily on seeds from immature fruits (Charles-dominique et al, 1981). Either or both of these ecological traits (eurytopy and granivory) might account, in part, for the broad geographic distribution of this species and its ability to coexist with other porcupines.…”

Phylogenetic analyses of cytochrome-b sequence data from 13 of the 15 currently recognized species of New World porcupines were used to test competing taxonomic hypotheses and to explore scenarios of morphological evolution and biogeography. Consistent with previous studies, the monophyly of Erethizontidae (Chaetomys + Erethizon + Coendou) and the monophyly of Erethizontinae (Erethizon + Coendou) were both strongly supported. However, cytochrome-b sequence data provide no support for the reciprocal monophyly of Coendou, "Echinoprocta, " and "Sphiggurus" as those taxa were previously recognized by authors. all of the erethizontid species recognized in recent revisionary work and represented by multiple sequences in this study were recovered as monophyletic groups. Maximum-likelihood (Ml) analyses of these data recovered the following phylogeny for 11 species of Coendou: ((melanurus (ichillus (pruinosus + vestitus))) ((spinosus (bicolor + nycthemera)) (prehensilis (mexicanus (quichua + rufescens))))). ancestral-state reconstructions based on the Ml topology suggest that several morphological characters emphasized in past erethizontid classifications (size, nasofrontal sinus inflation, and long fur) have evolved homoplasiously. Maximum-likelihood inference of geographic range evolution suggests that the last common ancestor of living erethizontids was a cis-andean species, and that most subsequent cladogenesis was also cis-andean; however, at least two trans-andean dispersal events are plausibly indicated, as well as two separate invasions of andean landscapes. among the most remarkable results of this study are almost-

“…The thin-spined porcupine is nocturnal, solitary, and arboreal, with low activity levels and a herbivorous diet (Giné et al, 2010). These characteristics are common in other species of arboreal rodents (Eisenberg and Redford, 1999).…”

ABSTRACT. Thin-spined porcupines (Chaetomys subspinosus) are threatened with extinction and are categorized as vulnerable. This is because of alteration to and loss of their habitat and possible hunting activities in their distribution area. Their spines constitute one of their defense mechanisms, which can be fomites for pathogens to humans. However, little is known about such pathogens. The present study aimed to detect bacteria on spines of C. subspinosus, from the Una Biological Reserve, South of Bahia, northeastern Brazil, by analyzing metagenomic DNA, isolating bacterial culture, using the denaturing gradient gel electrophoresis (DGGE) technique, and sequencing. Six anatomical points were selected for withdrawing spine samples from an individual C. subspinosus. At all sample points, bacteria were detected by bacteriological culture and/or DGGE and sequencing of excised bands. When all samples were combined, standard PCR-DGGE analysis of bacteria present in the spines identified 15 distinct bands, thereby revealing a distinct bacterial community. The main pathogens identified through sequencing were Bacillus cereus, B. thuringiensis, B. anthracis, and B. pumilus. The present study demonstrated the isolation and identification of non-pathogenic and pathogenic bacteria on the spines of C. subspinosus.

“…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.
