  • Larval development of Hexapanopeus paulensis Rathbun, 1930 (Crustacea, Brachyura, Xanthidae) under laboratory conditions

    Fransozo, Adilson; Mantelatto, Fernando Luiz Medina; Negreiros-Fransozo, Maria Lucia

    Resumo em Inglês:

    Four zoeal stages and one megalopa stage of Hexapanopeus paulensis Rathbun, 1930 were obtained from eggs of ovigerous females from the northern coast of São Paulo State, Brazil. The experiments were performed in a climatically controlled room at 24 ±1 ºC at a salinity of 34.5%, and the animals were fed with newly hatched Artemia salina nauplii. All larval stages are illustrated and described in detail. The complete larval development consists of 4 zoeal stages and 1 megalopal stage. The main morphological characters that allow the identification of the zoeae and megalopa of H. paulensis are analyzed with respect to the other species of Xanthidae's family from southern and southeastern Brazilian coast.

  • Nudacotyle carollia sp. nov. (Trematoda, Nudacotylidae) parasito intestinal de Carollia perspicillata L. (Chiroptera) en Colombia

    Velez, Imelda; Thatcher, Vernon

    Resumo em Inglês:

    Nudacotyle carollia sp. nov. (Trematoda, Nudacotylidae) is described on the basis of specimens from the intestinal tracts of three Colombian bats of the species Carollia perspicillata L. The new species resembles both of the genera of the family, Nudacotyle and Neocotyle, in the general position of the organs and in having a vertical cleft. It differs from Nudacotyle in the position of the ovary and cirrus sac and in the lenth of the ceca. The new species differs from Neocotyle in the shape of the body and the vitelline lobes and in the length of the ceca. The ventral cleft is considered to be an important generic character which can be used to unit all the species of both genera in the single genus, Nudacotyle.

  • Influência do tamanho da amostra na estimativa da riqueza em espécies em levantamentos de abelhas silvestres (Hymenoptera, Apoidea)

    Cure, José Ricardo; Bastos Fo., Guilherme S.; Oliveira, Ma. José Faccini de; Souza, Og Francisco de

    Resumo em Inglês:

    The effect of area size, number of collecting hours and months surveyed, on the estimation of relative richness of bees is analized. In order to characterize a biogeographical region, it is suggested to collect various samples of no less than 400 especimens for each one, in contrasting localities within a region, utilizing the usual standardized methodology for wild bees collecting. Thus, it is possible to have a better profit of the effort invested in the survey, making it possible to estimate the relative species richness among different biogeographical regions, in shorter periods of time.
  • Histologia geral dos intestinos do Caiman crocodilus yacare (Daudin, 1802) (Crocodilia: Reptilia)

    Jin, Sonia Maria; Maruch, Sandra Maria das Graças; Rodrigues, Marco Aurélio Martins; Pacheco, Paula

    Resumo em Inglês:

    General histology of small intestine (duodenum and jejunum) and the large intestine (colon and cloaca) of C. c. yacare (Daudin, 1802) Crocodilia-Reptilia. A comparative description is made of the histology of the small and large intestine of C. c. yacare. In all segments mucosa, submucosa, muscularis and serosa tunics were observed. The duodenum as very long villi, wich are well-developed and attached together to form irregular transverse ridges, covered with simple columnar epithelium with marginal and goblet cells. In the jejunum, the villi are shorter and less frequent. The colon as few folds, covered with the same epithelium; the lamina própria contains straight tubular glands with absortive cells, goblet and Paneth cells. The cloaca is very complex, with three well-defined regions: coprodeum, urodeum and proctodeum. In the coprodeum, the wall is folded, less muscular and the thin mucosa is covered by an epithelium with a few basal cells and mucosal cells. The urodeum as an additional external muscular tunic, with striated muscle fibers and a stritifield cylindrical epithelium with goblet cells. The proctodeum includes the free part of the penis in the male and, laterally, the ducts of a pair of holocrine cloacal glands. Near the opening of the ducts, the epithelium changes to a squamous keratinized type.

  • Cinco espécies de Lecithodendriidae (Trematoda) en murcielagos de Colombia, incluyendo tres nuevos generos

    Velez, Imelda; Thatcher, Vernon E.

    Resumo em Inglês:

    Velez, I. & V.E. Thatcher: Five species of Lecithodendriidae (Trematoda) in bats from Colombia, including three new genera. Three new neotropical genera and species of Lecithodendriidae (Trematoda) are described from Colombian bats. Sturniratrema umbilicata gen. et sp. nov. from Sturnira lilium differs from other genera in having an oval ventral depression, a dorso-ventrally curved cirrus and a genital pore lateral to the acetabulum. Chiropterotrema antioquiense gen. et sp. nov. from Carollia perspicillata is distinguished by having the acetabulum within a triangular ventral pit as well as an separation between the the male and female genital pores. Topsiturvitrema verticalia gen. et sp. nov. from Carollia perspicillata has a different orientation of the body, being nearly spherical but somewhat flatened in an anterior-posterior direction. This genus also has a deep ventral cleft separating two ventral lobes which are filled with eggs. Castroia silvai Travassos, 1928, is also reported from Anoura caudifer and Peropteryx macrotis. The first of these represents a new host record for the species. Addiotionally, Limatulum gastroides Macy, 1935, is reported from Lonchophyla robusta wich is another new host record.
  • Aspectos ecológicos dos Brachyura (Crustacea: Decapoda) no manguezal do Itacorubi, SC - Brasil

    Branco, Joaquim Olinto

    Resumo em Inglês:

    Ecological studies including occurrence, relative abundance and spatial distribution of 15 species of Brachyura, as well as the fluctuation in the annual cycle are carried out in mangrove (27º 34' 14" and 27º 35' 31" L.S.; 48º 30' 07"and 48º 31' 33" L. W.), during the year 1986. The hydrological parameters temperature, salinity and pH of surface and intersticial waters were also studied. Chasmagnathus granulata was the most abundant specie, followed by Uça uruguayensis, Aratus pisonii and Callinectes danae. The number of males was higher than females. In the spring a larger rate of Catches occurred. The species Eurytium limosum, Cardisoma guanhumi that had the state of São Paulo as their austral boundaru and Uça maracoani the state of Paraná, have now their boundaries of distribution expanded is for as the City of Florianópolis, in the state of Santa Catarina.

  • Estudo quantitativo do nervo frênico de rato albino em função do envelhecimento

    Souza, Romeu Rodrigues de; Watanabe, Ii-Sei; Chadi, Gerson; Araújo, Maria Vilma de

    Resumo em Inglês:

    The phrenic nerve of albino rats was studied for age changes in number of fibres, myelin sheath thickness and axon calibre. Nerves were excised from three young and three aged rats. There is no significant morphological differences between nerves from young and aged rats and no difference with age was found in the number of fibres, myelin sheath thickness and axon calibre.
  • Anatomia e histologia do aparelho reprodutor masculino de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae)

    Mesquita, Eliana de Fátima Marques de; Coelho, Arnaldo Campos dos Santos; Santos, Jefferson Andrade dos

    Resumo em Inglês:

    In this paper the authors give an anatomical and histological analysis of the male reproductive system of Pomacea canaliculata (Lamarck, 1822). Anatomically, the testis is better evidentiated than the ovary. In the structure of the testis a great number of very small channels converges to a single one. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. Histologically, the testis of immature males shows seminiferous ducts with round egg-shaped forms. In their lumens we could notice masses of cells that will originate spermatozoids. The penis has a conjunctive muscular sheath that can be seen in van Gieson's coloured preparations.
