ABSTRACT

Chapada Diamantina is located in central Bahia state, and has a large diversity of habitats, including important transitional areas, but has remained largely unstudied until now. In the present study we list the non-flying mammals of Chapada Diamantina National Park and surroundings. We captured only small non-volant mammals, medium and large mammals were assessed through indirect evidences (tracks and marks) and interviews. We recorded 58 species and 47 genera from seven Mammalian orders. Seven species are included in the list of endangered Brazilian species by IBAMA and IUCN; and other seven are classified as data-deficient. Species richness of small mammals was equivalent among sampled habitats, but species composition varied among habitats (10 in semi-deciduous forest, 9 in rocky savanna and 8 in cerrado sensu stricto), as some species are restricted by humidity to forest habitats. During four different samplings, eight species were collected only in open vegetation, four only in forests, and six in both habitats. Oligoryzomys rupestris and Gracilinanus microtarsus had its geographic range expanded. Faunal composition is similar to the one observed in the Atlantic Forest, including species from Cerrado and Caatinga. Besides, some species occupy different habitats from those previously ascribed to them.

Keywords: mammal diversity, zoogeography, Cerrado, Caatinga, Atlantic Forest.

RESUMO

A Chapada Diamantina está localizada na parte central do Estado da Bahia, apresentando grande diversidade de habitats, assim como áreas de transição. Seu isolamento da Mata Atlântica costeira por extensa área de vegetação aberta fazem com que seja uma região de particular interesse na compreensão dos padrões de ocorrência e evolução da mastofauna neotropical. Uma lista de mamíferos não voadores do Parque Nacional da Chapada Diamantina e arredores foi elaborada. O esforço de captura foi realizado apenas para pequenos mamíferos, assim, a sua composição e riqueza de espécies entre habitats (floresta decidual, cerrado sensu stricto e campo rupestre) foram calculadas. Visitas às coleções científicas permitiram, junto com os dados de coletas, a compilação de 58 espécies e 47 gêneros de sete ordens de mamíferos. Sete espécies estão incluídas nas listas de espécies brasileiras ameaçadas de extinção do IBAMA e do IUCN; e outras sete estão classificadas como espécies com pouco conhecimento. A riqueza de espécies de pequenos mamíferos foi equivalente entre os habitats sem relação com o esforço amostral e número de espécies coletadas (10 na floresta decidual, nove em campo rupestre e oito no cerrado sentido restrito). A composição de espécies de pequenos mamíferos variou entre habitats, já que algumas espécies são restritas a ambientes úmidos e com fitosionomia florestal. Durante os quatro períodos de captura foi observada uma maior afinidade de algumas espécies em relação ao tipo de vegetação: oito ocorreram apenas em vegetação aberta, quatro apenas em floresta e seis espécies nos dois tipos de habitats. Oligoryzomys rupestris e Gracilinanus microtarsus tiveram sua distribuição geográfica expandida. A composição faunística apresenta afinidades com a Mata Atlântica com a influência do Cerrado e da Caatinga, com algumas espécies ocupando habitats diferentes daqueles previamente registrados.

Palavras-chave: diversidade de mamíferos, zoogeografia, Cerrado, Caatinga, Mata Atlântica.

Introduction

Mammal diversity is strongly related to the history and evolution of continents (Eisenberg 1999). The present high diversity of mammals in the Neotropics is related to past climate changes mainly in the Andean region, with consequences all over South America (Reig 1986, Bush 1994, Cartelle 1999, Mortiz et al. 2000, Pardinãs et al. 2002, de Vivo & Carmignotto 2004, Grelle et al. 2005, Carnaval et al. 2009). Mammal trapping effort in Brazil has largely been concentrated on the Amazon and Atlantic Forest (eg. Mustrangi & Patton 1997, Patton et al. 1997, Percequillo 1998, Grelle 2000, Lara & Patton 2000, Moritz et al. 2000, Patton et al. 2000, Bonvicino et al. 2001, Costa 2003, Patton & Costa 2003, Gonçalves & Oliveira 2004). There are, though, a few studies carried out in Caatinga, Cerrado and Pantanal when compared with those carried out in the Atlantic Forest (e.g. de Vivo 1997, Bonvicino & Weksler 1998, Langguth & Bonvicino 2002, Basile 2003, Bonvicino et al. 2003, Oliveira et al. 2003, Carmignotto, 2004, Weksler & Bonvicino 2005).

Neotropical biomes are connected through transitional areas, for instance between the Atlantic Forest and Cerrado (Prance 1992; Eisenberg & Redford 1999) or Caatinga (Veloso et al. 1991; Rizzini 1997). Parque Nacional da Chapada Diamantina (PNCD) is located in the centre of Bahia state (11º and 14º S, 41º and 43º W), in a Y- shaped mountain range. Beside the PNCD be included in Caatinga domains, it has a wide range of habitats and altitudes, including swamp areas (locally called "marimbus"), caatinga, humid and dry forests, rocky savanna ("campo rupestre"), cerrado sensu stricto, and transitional areas (Brazão & Araújo 1981; Parrini et al. 1999). The Brazilian workshop "Avaliação e ações prioritárias para a conservação da biodiversidade da Mata Atlântica e Campos Sulinos" (Assessment and priority actions for biodiversity conservation of Atlantic Forest and Southern Grasslands) pointed out the whole Chapada Diamantina region as one of the priority areas for biodiversity conservation (Heringer & Montenegro, 2000).

Chapada Diamantina is considered a refuge for birds, reptiles, amphibians, mammals and the flora, with a unique faunistic formation since the Quaternary (Rodrigues-Filho et al. 2002). Those characteristics and the lack of available information (Conservation International of Brazil et al. 2000) make it an important area for research. Recently, Oliveira & Pêssoa (2005) published a study about the mammal fauna of the Chapada Diamantina, and before that, Gregorin & Mendes (1999) listed 11 species of bats. Bat fossils from the Pleistocene were also registered by Cartelle & Abuhid (1994) and Czaplewski & Cartelle (1998).

We herein present an account of non-flying mammal species of Chapada Diamantina National Park and surroundings, resultant of mammal trapping effort, museum collection and literature analysis. A report is also made on the species composition and richness of small mammals in three studied habitats (semi deciduous forest, cerrado sensu stricto and rocky savanna).

Materials and Methods

Information on mammal species and their occurrence sites in Chapada Diamantina was obtained through capture of small mammals, direct in situ observations, analysis of specimens from zoological collections (Museu Nacional do Rio de Janeiro - MN, Rio de Janeiro, Museu de Zoologia da Universidade de São Paulo - MZUSP, São Paulo and University of California Museum of Vertebrate Zoology - MVZ, Berkeley), and interviews.

The field sampling was carried out between 2002 and 2004, in different vegetation habitats (Table 1), different sampling efforts and in different year periods. Collecting licenses were obtained from IBAMA (02001.009093/02-23 and 02001.009074/02-86). Three kinds of live traps were used: Sherman^© (height: 10 cm, width: 8 cm, depth: 30.5 cm), Tomahawk^© (height: 15 cm, width: 14 cm, depth: 41 cm) with bananas, manioc and peanut butter as bait and pitfall. Sherman^© and Tomahawk^© traps were placed 15 m apart in lines on the ground and on trees, varying according to topography and presence of trees. Pitfalls were placed in star formations or lines only in semi-deciduous forest (Remanso and Margem do Rio Saminas), as rocky soil in other habitats did not allow digging holes.

Sampling effort differed among localities according to terrain conditions (Table 1), and a comparison was performed in those where a higher sampling effort was accomplished (more than 1,000 trap.nights) and more species (more than five species) were collected (semi-deciduous forest, cerrado sensu strictoand rocky savanna). Those vegetation types were found at six localities (Table 1). The total sampling effort measured in trap.nights was 10,897 for Sherman^© and Tomahawk^©, and 2,671 for pitfall, with a total of 13,568 trap.nights. Field work was carried out in eight localities: two in semi-deciduous forest (Remanso - 6,306 trap.nights, and Foz do Córrego do Brejão - 640 trap.nights), one in cerrado sensu stricto (savanna with trees reaching 3-8 m in height) (Torre da Tele-Bahia - 3,910 trap.nights), two in rocky savanna (mountain top vegetation known as;campo rupestre') (Rio Cumbuca - 720 trap.nights, and Pousada Pé-de-Serra - 210 trap.nights), one in a gallery forest (riparian vegetation along streams in cerrado landscapes) (Estação de Tratamento de Água de Mucugê - 201 trap.nights), one in "cerradão" (savanna with trees reaching 8-12 m in height) (Fazendo do Zé Leandro - 360 trap.nights) and one at the border of semi-deciduous forest and rocky savanna (Rio Saminas - 1,221 trap.nights), so both habitats were sampled (Table 1). Three vegetation types were the most sampled: semi-deciduous forest with 7,712 trap.nights (57%), cerrado sensu stricto with 3,910 trap.nights (29%), and rocky savanna with 1,385 trap.nights (10%).

Specimens were identified to the species level by comparison with specimens deposited in museums, and also by using morphological descriptions available for family Didelphidae (Mustrangi & Patton 1997; Costa et al. 2003; Voss et al. 2004, 2005), subfamily Sigmodontinae (Tribe 1996, 2005; Bonvicino et al. 1999; Gonçalves et al. 2005; Weksler & Bonvicino 2005; Weksler et al. 2006; Percequillo et al. 2008), and family Echimyidae (Lara & Patton 2000; Bonvicino et al. 2002; Basile 2003; Corrêa et al. 2005; Pessoa et al. 2005). Medium and large mammals were identified in the field using Emmons & Feer (1997), Eisenberg & Redford (1999) and Reis et al. (2006). Taxonomic nomenclature follows Wilson & Reeder (2005), as well as Bonvicino & Moreira (2001), Bonvicino et al. (2002), Costa et al. (2003), Weksler et al. (2006), Reis et al. (2006) and Bonvicino et al. (2008). Conservation status follows Machado et al. (2008) and the IUCN Red List of Threatened Species (IUCN, 2008; http://www.iucnredlist.org/details/730/0 - July 10^th, 2009). Vegetation types follow Veloso et al. (1991) and Juncá et al. (2005).

Voucher specimens (skull, skin and partial skeleton) were deposited at Museu Nacional do Rio de Janeiro (MN) and Museu de Zoologia da Universidade de São Paulo (MZUSP) (see ^Appendix).

Results

1. Species account

Fifty-eight non-flying mammal species were catalogued: 23 from field work, 17 from literature (Souza 2005; Oliveira & Pêssoa 2005), 23 from museum records and 21 from interviews and observations, with some species included in more than one category (Table 2). A total of 316 specimens of non-flying mammals were recorded during field work (Table 3 and Figure 1), including collected (260), captured-and-released (51), road-killed specimens (four) and observations (one). Out of the 316 specimens recorded during field work (Table 2), 237 (75%) are rodents, 69 (22%) are marsupials, five (1.5%) are armadillos, three are carnivores (1.24%) and one is a primate (0.32%). Our database, including museum records, totalized 590 specimens of mammals (see ^Appendix).

Seven species are cited in the Brazilian official list of endangered species (Machado et al. 2008 - IBAMA; IUCN 2008). The fat-tailed mouse opossum (Thylamys karimii) is considered Vulnerable by IUCN and Data-deficient by IBAMA. The giant anteater (Myrmecophaga tridactyla) is considered Vulnerable by IBAMA, but do not appear in the IUCN list. Three monkeys are presented in both list: Alouatta caraya (Critically endangered - IBAMA and Least Concern - IUCN), Cebus xanthosternus (Critically endangered in both lists) and Callicebus personatus (Vulnerable in both lists). Two felines are also present in both lists: Panthera onca (Vulnerable - IBAMA and Near Threatened - IUCN) and Puma concolor (Vulnerable - IBAMA and Least Concern - IUCN). Another six species (one armadillo, Cabassous tatouay; and six rodents, Oligoryzomys rupestris, Rhipidomys cariri, Dazyprocta azarae, Phyllomys blainvilli, Thrichomys inermis and Trinomys albispinus) are classified as data-deficient species in both or one of the lists (Machado et al. 2008 - IBAMA; IUCN 2008).

2. Habitat comparisons

Despite differences in capture effort (Table 1), species richness of small non-flying mammals was similar among the most sampled vegetation formations (Figure 2): 10 species were obtained in semi-deciduous forests, nine in rocky savanna and eight in cerrado sensu stricto. Comparison of the data obtained in open vegetation habitats (rocky savanna and cerrado sensu stricto) shows that although rocky savanna had one third of capture effort, when compared to cerrado sensu stricto (1,616 and 3,910 trap.nights, respectively), it has a higher species richness (nine species in rocky savanna and eight in cerrado sensu stricto).

Species composition differed among vegetation formations (Figures 3, 4 and 5). Oligoryzomys nigripes, O. fornesi and Rhipidomys sp. were collected only in the semi-deciduous forest, whereas Calomys expulsus, Pseudoryzomys simplex and Wiedomys pyrrhorhinos were recorded only in open vegetation (rocky savanna). However, species that were not habitat-dependent, such as Akodon cursor, trapped in semi-deciduous forest and in cerrado sensu stricto, and Cerradomys vivoi, sampled in all habitats surveyed (Table 4). Eight species were collected only in open vegetation habitats, five species only in forested habitats, and five in both (Table 4).

Species frequencies were not equivalent in each vegetation formation. Marmosops incanus was the most common species in semi-deciduous forest with 43 individuals captured, Cerradomys vivoi was the most common in cerrado sensu stricto with 40 individuals, and Thrichomys inermis was the most common species (42 individuals) captured in the rocky savanna (Figures 3 to 5). Besides, Cerradomys vivoi and Thrichomys inermis were among the most four common species. Cerradomys vivoi correspond to 86% of the specimens collected in "cerradão", 64% in gallery forest, 55% in cerrado sensu stricto, 28% in rocky savanna, and 14% in semi-deciduous forest. Thrichomys inermis present 42% of individuals captured in rocky savanna, 18% in semi-deciduous forest and gallery forest, and 14% in cerrado sensu stricto. Among the arboreal species, Gracilinanus microtarsus and Rhipidomys sp. were collected in semi-deciduous forest, Micoureus demerarae in cerrado sensu stricto, and Marmosops incanus in both semi-deciduous forest and cerrado sensu stricto (Table 4, Figures 3, 4 and 5). In those three localities where traps were settled in semi-deciduous forest, M. incanus was the most abundant species (39%), but it was the scarcest in those localities with open vegetation, with less than five specimens (2.7%) in cerrado sensu stricto (Figure 4), and absent in rocky savanna, gallery forest and "cerradão" (Figure 5).

Discussion

Here we are presenting the results of a mammal sampling effort in the Chapada Diamantina, as described in Table 1. In Chapada Diamantina 58 non-flying mammal species were recorded, including 34 species of small non-flying mammals, nine marsupials from the Family Didelphidae, and 25 species of rodents (excluding Hydrochoerus hydrochaeris), one of the Family Sciuridae, 16 of the Family Cricetidae, two of the Family Caviidae, one of the Family Dasyproctidae, one of the Family Cuniculidae, and four of the Family Echimyidae.

Since the complete Chapada Diamantina was not surveyed, more field work is necessary to provide more detailed information about mammals' occurrence. Long-term studies can generate longer species list, as observed by Olifiers et al. (2007) with an effort of 59,290 trap.nights. According to those authors, at Serra dos Órgãos National Park, in Rio de Janeiro state, where a five-year long survey (1996 to 2000) was carried out, 27 small mammal species were registered, including rodents and marsupials, but Juliomys rimofrons and J. ossitenius were only trapped at the end of the study (Olifiers et al. 2007). The trapping effort made by the authors during five expeditions to Chapada Diamantina (13,568 trap.nights), with sporadic collecting effort, does not provide a mammal list for the region that can be considered nearly completion. As an example, among the non-flying small mammals, the addition of Monodelphis americana, Nectomys rattus, Oxymycterus dasytrichus, O. delator, Trinomys albistinus and T. minor follows Souza (2005) and Oliveira & Pêssoa (2005), since we do not sampled this taxa. On the other hand, Souza (2005) and Oliveira & Pêssoa (2005) did not record Thylamys karimii, Wiedomys pyrrhorhinos and Pseudoryzomys simplex, which were sampled during our field sampling and thus included in the present list.

The number of mammals species herein recorded in 13,568 trap.nights, together with the information obtained from museums and the literature, is comparable, in terms of number of species, to the list of Itatiaia National Park, with 69 species (Geise et al. 2004), which shows that in spite of the difference of vegetation types, these two regions exhibit a similar species richness. Itatiaia National Park has only Atlantic Forest areas, a very humid climate, with tropical wet forest and grassland altitude fields ("campos de altitude") habitats whereas Chapada Diamantina National Park harbors areas of Atlantic Forest, Caatinga and Cerrado.

If a comparison of species richness and vegetation types can be made, as already suggested by Oliveira & Pessôa (2005) that would be with the Chapada dos Veadeiros and Chapada Diamantina. Comparing the species composition between these two areas, we observed that nine species (five rodents and four marsupials) were found in both Chapadas (Bonvicino et al. 2005 and the present study): the similarity of species composition was about 15%, and the species that occurs in both Chapadas are Didelphis albiventris, Gracilinanus agilis, Monodelphis domestica, Micoureus demerarae, Calomys expulsus, Necromys lasiurus, Oligoryzomys rupestris, Oxymycterus delator, and Pseudoryzomys simplex. All these species are characteristic of open vegetations from Cerrado (see Carmignotto, 2004), corroborating the similarity between Chapada Diamantina and Chapada dos Veadeiros.

Some species reported by us here have had their known geographic distribution extended. Gracilinanus microtarsus known distribution, according to Patton & Costa (2003), Costa et al. (2003), and the IUCN Global Mammal Assessment (IUCN 2008), ranges from Paraná state to northern Rio de Janeiro and southern Minas Gerais states, with an isolated record of G. microtarsus from Una, southern Bahia (Pardini, 2004). The record of Chapada Diamantina presented here is the second for the state, extending the species distribution to one of the few and most important forest remnants in the northeast Brazil (Câmara, 2003). Oligoryzomys rupestris was, until now, observed in two localities: Alto Paraíso (Minas Gerais) and Pico das Almas (Bahia) (Weksler & Bonvicino 2005). The collected specimens at Chapada Diamantina increased the species northernmost limit by 92 km (from 13º 33' S and 41º 56' W to 13º 10' S and 41º 10' W). The current northernmost occurrence of Cabassous tatouay was in Minas Gerais state, at Igarapé municipality (20º 04' 13.8" S-44º 18' 6.12" W; E.M.V.C. Câmara, pers. comm), and the present record extends considerably the distribution of this species northwards, being also the first record to northeastern Brazil (Gardner, 2007). All these range expansions reflect the lack of available data on these species distribution ranges in the Neotropics.

We observed some representatives of the Atlantic Forest mammalian fauna, a similar pattern observed by Parrini et al. (1999), which reported species from different biomes occurring in sympatry in the Chapada Diamantina, pointing out a mosaic between faunal composition in open biomes (Cerrado-Caatinga) and forests (Atlantic Forest). Another point concerning the here reported mammal diversity is that the Caatinga area in Chapada Diamantina is considered as one of the priority areas for conservation because of the presence of contact areas with others biomes (Cerrado and Atlantic Forest), their isolation and a presumably high species diversity (Oliveira et al. 2003).

We believe that the occurrence of syntopic species in the Chapada Diamantina, from both open and forest habitats could indicate:

a) inadequate definition of their habitat specificities;

b) insufficient studies to properly define the patterns of geographical distribution;

c) the tendency to adapt to different habitats;

d) the lack of habitat specificity; and

e) the mosaic structure of vegetation of the region.

In the present study we recorded two species that are common to open areas (Cerrado and Caatinga), but that in Chapada Diamantina were found in forests (semi-deciduous Forest). Thrichomys inermis, which is usually found in dry environments like Caatinga and Cerrado (Basile 2003), was also captured by us in semi-deciduous forest (locality 4), as well as Oligoryzomys rupestris (Weksler & Bonvicino 2005). In both cases the semi-deciduous forest area was located beside the rocky savanna.

The here now presented list of mammal species of Chapada Diamantina exhibits species of Atlantic Forest, Cerrado and Caatinga (Fonseca et al. 1996; Costa et al. 2000). Furthermore, some species are present in other environments than previously recorded. All characteristics herein mentioned turn Chapada Diamantina into a region of biogeographic importance, that present vegetations of three biomes and a mammal fauna that represent a transition region.
