Contribuição à herpetologia da Argentina e do Rio Grande do Sul, Brasil por William Wright Milstead (Amphibia, Reptilia)

Abstract

ABSTRACf. CONTRJBUTION TO TI-IE I-IERPETOLOGY OF ARGEN-TINA ANO RJO GRANDE DO SUL, BRAZIL BY WILLIAM WRJGI-IT MILSTEAD (AMPI-IIBIA, REPTILIA). ln lhis pape r wC are presenting lhe list or lhe specimens and the laxa oblained; lhere are 73 names of species bel onging to 40 genera, of which 32 species and B genera are amphibians, and 42 species and 27 genera are repliles. There are several field nOles of Milstead and manydala on lhe snakes studied by Lema with Milstead. The collection was widespread by Milstead to several institutions, but mainly to Field Museum of Natural I-listory, Chicago, and Museu Nacional do Rio de Janeiro, Brazil. KEY WORDS. Zoogeography, Amphibia, Reptilia , Argenlina, Brazil Esta publicação foi motivada pelo desejo de homenagear o Dr. William Wrightt Milstead, herpetólogo ecologista que esteve residindo em Porto Alegre durante três anos, tendo se dedicado ao colecionamento de exemplares da herpetofauna da área. Sua dedicação despertou o interesse de professores e alunos da Universidade Federal do Rio Grande do Sul, que passaram a colecionar espontaneamente, tendo deixado amigos e uma lacuna com seu falecimento posterior. Milstead veio ao Brasil procedente dos Estados Unidos da América, como ecologista, para trabalhar em projeto do Departamento de Genética da Universidade Federal do Rio Grande do Sul. Sua vinda decorreu do pedido feito pelo chefe do departamento, Dr. Antonio Rodrigues Cordeiro, à Rockeffeler Foundation, financiadora do projeto, e que tratava do estudo de populações naturais de Drosophilidae. Mas Milstead era herpetólogo e, uma vez em Porto Alegre, dedicou-se totalmente ao colecióhamento herpetológico. Milstead saía com as viaturas do então Instituto de Ciências Naturais (hoje repartido em Instituto de Geociências e Instituto de Biociências). Coletava, geralmente, nas rodovias. Com o tempo, professores e alunos aderiram, auxiliando consideravelmente a coleção. Para o tombamento dos especimens e de dados, organizou diversos fichários, cujas fichas tinham cores diferentes

A cladistic analysis of Scinax (Anura: Hylidae)

“…Almeida and Cardoso (1985) did not question the presence of a sperm with double tail, though they commented that the flagella moved like a single element. These ideas were also followed explicitly or implicitly (by employing Hyla instead of Ololygon) by Peixoto (1982, 1984), Haddad et al (1988Haddad et al ( , 1990, Cardoso and Martins (1987), Haddad and Sazima (1992), Langone (1991), Andrade andCardoso (1987, 1991), Abe and Neto (1991), Langone and Prigioni (1988), Klappenbach and Langone (1992), de Lema and Braun (1993), Taboga and Dolder (1993), Rossa-Feres and Jim (1994), and Martins (1998). noticed that some species of Ololygon (based on representatives of the then O. catharinae, O. staufferi, and O. rubra species groups) had the ability to bend their thumbs and first toes backward and suggested that this could be a synapomorphy of the genus.…”

A cladistic analysis of Scinax (Anura: Hylidae)

“…The authors seemed to suggest that the degree of morphological variation between both groups is equivalent to that among other species groups of Hyla, and presumably because of this, placing the two groups in a single genus is not justified. These ideas were also followed explicitly or implicitly (by employing Hyla instead of Ololygon) by Peixoto (1982, 1984), Haddad et al (1988Haddad et al ( , 1990, Cardoso and Martins (1987), Haddad and Sazima (1992), Langone (1991), Andrade andCardoso (1987, 1991), Abe and Neto (1991), Langone and Prigioni (1988), Klappenbach and Langone (1992), de Lema and Braun (1993), Taboga and Dolder (1993), Rossa-Feres and Jim (1994), and Martins (1998). Almeida and Cardoso (1985) did not question the presence of a sperm with double tail, though they commented that the flagella moved like a single element.…”
