    Abstract: We studied the richness and distribution o anuran species on dierent breeding sites at the ReservaEcolgica da Michelin (13 50 S and 39 10 W, approximately 90-400 m above sea level), Municipality oIgrapina, Bahia State, Brazil. The reserve includes ragments o Atlantic Rain Forest varying rom 140 to 650 ha.Five types o environments were sampled: lea litter inside orest ragments, streams inside orest ragments,dam on the edge o orest ragment, temporary pond inside orest, and temporary ponds inside banana and rubbergroves along the eastern boundary o the reserve. We used active and passive sampling methods or surveys

    o amphibians, between March 2007 and December 2008. We captured 48 species distributed in 10 amilies(number o species in parentheses): Aromobatidae (1), Brachycephalidae (4), Buonidae (2), Craugastoridae (1),Centrolenidae (1), Cycloramphidae (3), Hylidae (29), Leiuperidae (1), Leptodactylidae (3), and Microhylidae (3).Temporary ponds presented the highest number o species in reproductive activity (19 species in native orestedareas, and 21 in plantation areas), while lea litter presented the lowest (6 species). Two species were ound inbromeliads (Phyllodytes melanomystaxand P. luteolus). Twenty-two species were exclusive to ragments o orest,11 were ound only in anthropized areas (dam, and rubber and banana plantations) and 15 in both environments.Aplastodiscuscavicola andDendropsophus giesleri had their geographic distribution extended to the State oBahia. Phasmahyla timbo and Chiasmocleis cordeiroi known only rom their type localities were ound in thereserve.Keywords: inventory, geographic distribution, breeding sites, baixo sul.

    Introduction

    In the Neotropical region, the loss o habitat and the ragmentationo natural environments are consequences o extensive agriculture,among other causes (Whitmore 1997). Although little inormation isavailable on the distribution o organisms in cultivated environments,it is known that the richness and abundance o animal species

    are strongly inuenced by the size and the surrounding naturalenvironments (Bernnett et al. 2006). Regarding the Atlantic RainForest, such ragments play an important role in the conservationo biodiversity due to the high levels o endemism observed in thisbiome, currently threatened by the loss o habitat generated mainlyby urbanization and agriculture (Morellato & Haddad 2000).

    In this context, the loss o natural resources is a signifcant concernwith regard to the anuran auna (Duellman 1999). The Atlantic RainForest houses approximately 400 species o anurans, which comprisesalmost 50% o all the species known to occur in Brazil (Silvano &Segalla 2005, Haddad et al. 2008). Probably, such species richnessis supported by the heterogeneity o environments and the variety omicrohabitats ound in that biome (Cardoso et al. 1989).

    The availability o aquatic environments is crucial or thereproduction o most anuran species and the type o aquatic environmentcould determine their reproductive modes (Duellman & Trueb 1986). Inthe reproductive period, anurans can use ponds, lakes, bogs, streams, andphytothelms, comprising 39 dierent reproductive modes, 27 o themound in the Atlantic Rain Forest (Haddad & Prado 2005).

    The southern coast o the State o Bahia is located within theAtlantic Forest Domain (AbSber 1977), one o the 25 world hotspotsor biodiversity conservation (Myers et al. 2000) and divided intothree political regions: Baixo Sul (14 municipalities), LitoralSul (27 municipalities), and Extremo Sul (21 municipalities)(Secretaria ... 2010). Silvano & Pimenta (2003) ound 115 speciesin southern Bahia (which encompasses 107 municipalities in thedefnition they used), and Carnaval et al. (2009) observed a higher

    genetic diversity in the populations o this region when compared topopulations o other parts o the Atlantic Rain Forest.Publication o species lists has been undamental or the

    understanding o the biodiversity and potentialities o Neotropicalorests (Duellman 1999, Silvano & Segalla 2005). Moreover, itis difcult to plan conservation strategies without the minimumknowledge regarding the local species composition (Santos 2003).

    This study aimed to inventory the anuran species o the ReservaEcolgica da Michelin located in the Municipality o Igrapina,Baixo Sul o the State o Bahia, Brazil, mainly within potentialbreeding sites.

    Material and Methods

    1. Study area

    The Reserva Ecolgica da Michelin is located in the Municipalityo Igrapina, State o Bahia, Brazil (13 50 S and 39 10 W, 90 to383 m above sea level), in a region known as Baixo Sul, 200 kmSouth rom the State capital city o Salvador. Rainall occursthroughout the year and largely varies between years (K. Flesher,pers. comm.). Mean annual precipitation in the reserve over the last10 years was approximately 2000 mm, temperature ranged rom21.7 to 30.8 C, and air humidity between 80 and 85%. During thestudy period intense precipitation occurred between February andMay (rainy season) and low precipitations between October andJanuary (dry season; Lima & Junc 2009).

    The reserve comprises two ragments o Atlantic Rain Forest o325 and 650 ha under dierent stages o regeneration. The major

    ragment is part o a 13.000 ha Atlantic Forest patch and the otherone is the sum o three distinct but connected areas. Rubber (Haveabrasiliensis), cacao (Theobroma cacao), and banana plantations(Musa sp.), and a mixed tree crop groves with some manioc are alsopart o the landscape. The ollowing habitats were investigated:

    Temporary ponds in orest ragments:two ponds were sampled. Thelargest pond had up to 50 cm depth, area o approximately 180 m2, and

    was surrounded by grass, shrubs, and 10 m high trees (Figure 1a). Whenully flled with water (September and October 2007; June and July 2008)it presented muddy bottom, and when empty deposits o organic matterrom lea and plant decomposition. The smallest pond was located atthe orest edge and was ully flled with water only in July 2008. It wassurrounded by large trees and shrubs, presented sandy bottom, depth upto 25 cm, and area o approximately 16 m2.

    Temporary ponds in plantations: these were sampled inplantations o rubber trees (shaded, n = 1), banana (open area, n = 1,Figure 1b), and abandoned or rarely used roads (shaded, n = 2). Thearea and depth o the ponds varied rom 3 m2 and 30 cm to 180 m2and70 cm, respectively.

    Streams: seven slow-owing streams located inside the orest

    (Figures 1c, 1d). Bottoms always presented rocks and other elementsvarying rom sand to mud. The deepest stream was up to 50 cmapproximately, and width varied rom 90 to 250 cm. Portions rom25 to 100 m were sampled.

    Permanent pond in open area: one artifcial dam surroundedby grass and shrubs (Figure 1), presenting muddy bottom, area o600 m2, and up to 2 m depth.

    2. Specimens sampling

    Two to three researchers sampled the area by active and passive(pitall traps) methods. Active methods were employed on two to

    our nights rom August 2007 to July 2008, and in December 2008,lasting rom fve to eight hours each night. Specimens were sampled inorest ragments and cultivated areas, mainly near waterbodies, whichrepresented breeding sites or most species. Tadpoles were sampledduring the day in all types o waterbodies, in orested and non-orestedareas. Species identifcation was based on part o a lot o the tadpolescollected, which was maintained in captivity in a plastic box withabout 3 L o water, where they were ed on until metamorphosis wascompleted. One temporary and one permanent pond were monthlysampled between August 2007 and July 2008. Other places weresampled irregularly, with more eort during the wet periods.

    In order to capture lea litter rogs, eighty pitall traps (30 L plasticbuckets with drit ence o 3 m long; Figure 1e) were installed insidetwo orest ragments at distinct areas rom those o active sampling.Eight sampling units (SU) were placed at least 2 km rom each other(three SU inside the 650 ha ragment and 5 in the 325 ha ragment).Each sampling unit contained 10 pitall traps separated rom eachother by 10 m using an L design (the drit ence did not extend romone plastic bucket to other one). Such traps were kept active during10 consecutive days in the months o March, May, July, September,and December 2007, totalizing an eort o 1200 hours (or 800 pitalltraps-night x excursion). All voucher specimens were deposited inthe Museu de Zoologia da Universidade Estadual de Feira de Santana(MZUEFS) (Apendix 1).

    Results

    Forty-eight species distributed into 10 amilies were registered(Table 1). Among the species sampled by active methods (n = 46),Vitreoranasp.(Centrolenidae) andAplastodiscusc. sibilatus (Hylidae)were captured exclusively in larval stages. Thirteen species belonging to8 amilies were captured in the pitall traps, all o them also captured by

    active methods, except byIschnocnema paulodutrai andI. bilineata.Among the habitats sampled by active methods, temporary

    ponds inside orest and plantations (rubber and banana) presented thehighest number o species in reproductive activity (19 and 21 species,respectively), while lea litter presented the lowest number (6 species). Twospecies were ound in epiphytes and terrestrial bromeliads (Phyllodytesmelanomystaxand P. luteolus,Figures 2j and 2k, respectively). Scinaxx-signatus (Figure 2h) demonstrated high environmental plasticity,occurring in permanent and temporary ponds in open and orested areas(Table 1). On the other hand, 25 species were restricted to one type ohabitat and environment (Table 1), o which onlyHypsiboas atlanticus(Figure 2b),Hypsiboas semilineatus (Figure 2e), and Scinaxa. alter(Figure 3l) occurred outside native orest. Twenty-two species were

    exclusively ound inside the orest, 11 only in anthropized areas (openareas and rubber plantations) and 15 in both environments.Among taxa identifed to the specifc level, 35% are currently

    categorized as decreasing, 33% as stable, and 16% have their statuso conservation unknown (International... 2009; Table 1).

    Remarks on Geographic Distribution

    Bokermanohyla capra (Figure 3c), Ischnocnema bilineata,I. paulodutrai , I. vinhai (Figure 4j), and Hylomanti s aspera(Figure 2g) are endemic to the State o Bahia (Napoli & Pimenta2009, Junc & Pimenta 2004, Pimenta & Junc 2004, Peixoto &Pimenta 2004, Silvano & Pimenta 2004, respectively). Phasmahylatimbo and Chiasmocleis cordeiroi, also endemics to the BahiaState, were previously known only rom their type localities in themunicipalities o Amargosa (150 km North rom Igrapina) andCamamu (14 km South rom Igrapina), respectively.Aplastodiscuscavicola (Figure 2a) was known only or the States o Minas Geraisand Esprito Santo (Cruz et al. 2004), and Dendropsophus giesleri(Figure 2) or the States o Esprito Santo, Rio de Janeiro, and SoPaulo (Carvalho-e-Silva & Telles 2004). The records o both species inthe Municipality o Igrapina extend their distributions approximately700 km Northwards.

    Discussion

    Silvano & Pimenta (2003) studied 21 Atlantic Rainorestremnants in 19 municipalities rom Southern Bahia and registered115 species o anurans, a very expressive number, which correspondto almost 25% o the total anuran richness or the Tropical AtlanticForest (Haddad et al. 2008). Among the localities they sampled, thearea with the highest species richness was the Reserva Particular

    do Patrimnio Natural (RPPN) Estao Veracel (ormerly RPPNEstao Veracruz; see Pimenta et al. 2007), Municipality o PortoSeguro, with 39 species. In that work, the sampled localitiescloser to the Reserva Ecolgica da Michelin are situated in themunicipalities o Cairu, Nilo Peanha, and Camamu, where theyound 18, 23, and 32 species, respectively. Although speciesrichness were smaller than that ound at Igrapina, the sum o thesethree localities results in 40 species, a number close to that observedat the Reserva Michelin. It is important to note that the samplingdeveloped by Silvano & Pimenta (2003) lasted our nights in eacho these ragments and only active searches were used. Also, the

    habitats investigated in Cairu were represented mainly by arborealrestinga (see Pimenta et al. 2009), an habitat very distinct romthose ound at the Reserva Ecolgica da Michelin. Thus, the largernumber o species ound at the Reserva Ecolgica da Michelinpossibly is the result o the larger eort on active searches, theuse o pitall traps, and the dierent habitats and environmentssampled. Even so, many species ound in the localities sampledby Silvano & Pimenta (2003) were not ound at the Reserva daMichelin and vice-versa, showing that when we consider theanuran richness o this region as a whole, levels o diversity andendemism are very high.

    The high number o anuran species (n = 35) occurring in only onetype o breeding site (temporary ponds) is related to the reproductivemodes o these species, which limit the use o some habitats andmicrohabitats (Bertoluci & Rodrigues 2002). Based on the tadpoles

    sampled and on calling sites, only Dendropsophus branner i,D. elegans, Hypsiboas crepitans, Phyllomedusa burmeisteri, Scinaxeurydice, S. x-signatus, and Leptodactylus latrans used more thanone breeding site (temporary and permanent ponds). Species oundbreeding in streams were exclusive to this environment.

    Some habitats and environments at the Reserva Ecolgica daMichelin were not surveyed in this study (e.g. bamboo areas andcanopy), or had a little sampling eort (bromeliads). Sampling eortstandardization including such environments could increase anuran

    richness in this reserve.Sixty seven percent o the species captured in the Reserva

    Ecolgica da Michelin are currently categorized as Least Concern(LC), 17% as Data Defcient (DD), and 13% have their conservationstatus unknown (International... 2009, Table 1). Most LC species ishighly tolerant to environmental degradation or is known by its successin several types o environments. Allobates olersioides (Figure 4a)was the only species characterized as Vulnerable (VU: Verdade2008) andAplastodiscus cavicola (Figure 2a) as Near Threatened(NT; Cruz et al. 2004). Conservation status o both species was defnedaccording to geographical distribution covering areas where habitatquality is threatened due to deorestation and agricultural development.Moreover, none o the species recorded in this study were listed asthreatened by Ministrio do Meio Ambiente (MMA) (Haddad 2008),

    although the method employed to defne the species status conservationwas the same used by IUCN (Haddad 2008).

    Finally, a considerable percentage (45.3%) o the speciescaptured in the Reserva Ecolgica da Michelin is endemic to theAtlantic Rain Forest, two o them previously known only rom thetype locality. Despite controversy between IUCN and MMA speciesrog conservation status, in this study one species was consideredVulnerable and another Near Threatened (International... 2009).These results emphasize the importance o these orest ragments
