Natural history of Holoaden luederwaldti (Amphibia: Strabomantidae: Holoadeninae) in southeastern of Brazil
No full textThis study reports the rediscovery of Holoaden luederwaldti Miranda-Ribeiro, 1920 and provides information on the distribution, sexual dimorphism, reproduction and vocalization of a population of this species in Campos do Jordão, São Paulo (southeastern Brazil). Sampling was carried out in the Parque Estadual de Campos do Jordão (PECJ) from October 2005 through December 2008. Collecting was conducted using pitfall traps with a drift-fence on different altitudinal gradients (1,540 m, 1,780 m and 2,000 m a.s.l.). Fifty-two specimens of H. luederwaldti were collected in the PECJ. The mean snout-vent length (SVL) was 36.17 mm for males and 42.61 mm for females, indicating sexual dimorphism in body size. Holoaden luederwaldti occurred during the warm-rainy months. The population was distributed between 1500 and 2000 m, and the greater abundance was registered in well preserved forest areas. Mature females contained from 36 to 41 oocytes and the mean of oocyte diameter was 3.72 mm. The advertisement call of H. luederwaldti consists of simple notes composed of three harmonics. The record of the population of H. luederwaldti in the PECJ has reinforced the importance of investigating different areas of the forest when conducting faunal surveys

Dorsal surfaces of the head, body, and limbs deeply dark brown. The glandular portion of the lateral surface dark brown; flanks and ventral surfaces of the body and limbs slightly lighter than dorsum; palmar and plantar tubercles and tips of digits light gray; eyes black (Fig. 5). Variation. Males were smaller and with more robust forearms than females (Tables 1 and 2). Otherwise, no conspicuous qualitative differences were found between the available specimens, which were very similar to the holotype in external morphology and color pattern. Distribution. So far, Holoaden suarezi was recorded in three localities of high altitude (between 900 and 1300 m) in the State of São Paulo, situated in the Atlantic Forest Domain (sensu Ab’Saber 1977) of the Serra do Mar mountain range. The three localities are situated in the municipalities of Bananal (Estação Ecológica de Bananal), São José do Barreiro (Parque Nacional da Serra da Bocaina), and Salesópolis (Estação Biológica de Boracéia) (Fig. 6). Currently, Holoaden suarezi is endemic of the Serra do Mar in the State of São Paulo, and is geographically isolated from H. luederwaldti and H. bradei, which are endemic species of the Serra da Mantiqueira mountain range. Although H. pholeter also occurs in the Atlantic Forest Domain of the Serra do Mar mountain range, it is an endemic species of the Serra dos Órgãos that corresponds to a geographically isolated eastern portion of the Serra do Mar in the State of Rio de Janeiro (Pombal et al. 2008; Martins 2010). Etymology. A patronym honoring José Roberto Alves Suarez, Forest Ranger from the Instituto Florestal of São Paulo who dedicated most of his long-time career to the preservation of São Paulo’s high altitude Atlantic forest remnants and their fauna. Natural history. The holotype and paratype MZUSP 138348 were captured in pitfall traps during the months of highest precipitations (November and December 2003). Heyer et al. (1990) mentioned that MZUSP 23794 was taken from the ground on a forest trail at night. MZUSP 23794 contained a small number of large and unpigmented eggs. Similar eggs were reported in H. bradei (Lutz 1958), H. luederwaldti (Martins 2010), and H. pholeter (Pombal et al. 2008). Its vocalization is unknown.Published as part of Martins, Itamar A. & Zaher, Hussam, 2013, A new species of the highland frog genus Holoaden (Amphibia, Strabomantidae) from cloud forests of southeastern Brazil, pp. 178-188 in Zootaxa 3599 (2) on pages 179-185, DOI: 10.5281/zenodo.22273
Análise bioacústica do canto de anúncio em Hyla nana e Hyla sanborni na região de Botucatu, Estado de São Paulo, Brasil
No full textAs características relacionadas à comunicação sonora em duas espécies aparentadas, Hyla nana e H. sanborni, pertencentes ao grupo nana de espécies, foram estudadas, entre agosto de 1997 e junho de 1999, em duas poças permanentes de grande porte em área aberta na região de Botucatu, Estado de São Paulo. Foram obtidas gravações de 131 exemplares, 71 indivíduos de H. nana e 58 de H. sanborni, durante início de atividade de vocalização e atividade de vocalização em coro. Houve diferença nos ritmos de emissão de notas dos cantos entre o início das atividades e durante os coros. O canto de anúncio das espécies consiste na emissão de séries consecutivas de notas simples, pulsadas, com taxa de repetição rápida. Hyla nana e H. sanborni apresentam dois tipos de notas em seu canto de anúncio, denominados aqui como tipos A e B. Notas do tipo A, introdutórias, apresentam maior duração e número de pulsos, e suas emissões foram mais freqüentes durante o início das atividades de vocalização. As notas introdutórias são as primeiras da série emitida em atividade de coro. As notas do tipo B, secundárias, são curtas e com menor número de pulsos, sendo emitidas durante as vocalizações em coro. Os dois tipos de notas encontrados diferem significativamente em sua estrutura temporal. As duas espécies apresentaram segregação acústica tanto na estrutura espectral como na temporal de seus cantos de anúncio.Vocal communication traits of Hyla nana and Hyla sanborni, of the nana species group, were studied from August 1997 until June 1999 in two large permanent ponds located in an open field in Botucatu, São Paulo State. One hundred thirty-one individuals, 71 of H. nana and 58 of H. sanborni, were recorded in the beginning of their vocalization activity and during chorus vocalization. The rhythms of sound emission on the two occasions were different. An advertisement call consists in a consecutive series of simple notes in rapid succession. Both species have two types of notes in their advertisement calls, here named types A and B. Type A notes are introductory and have a longer and higher pulse number and are emitted more frequently in the beginning of vocalization activity. Introductory notes are the first to be emitted in chorus activity. Type B notes are secondary, of shorter duration and lower pulse number, and are emitted during chorus vocalization. The notes of both types differ significantly in their temporal structure. Both species present acoustic segregation in both spectral and temporal structure.Universidade de Taubaté Depto. de Biologia Lab. de ZoologiaUNESP Depto. de ZoologiaUNESP Depto. de Zoologi
