  • Influência das variáveis ambientais na fauna acompanhante na pesca da manjuba Anchoa tricolor (Agassiz) (Actinopterygii, Engraulidae) na Baía de Sepetiba, Rio de Janeiro

    Silva, Márcio de Araújo; Araújo, Francisco Gerson

    Resumo em Inglês:

    Anchoa tricolor (Agassiz, 1829) is the only anchovy of commercial importance in Sepetiba Bay, supporting an intensive commercial fishery by small sized seine boats provide of hydroacustics sounder detecting device. This study analyses the accompanying fauna in the A. tricolor fishery, and the influence of environmental parameters in fish composition. Seven samples were taken with a seine net between March and September 1999, capturing 114,430 fish, comprising 17 species and 11 families. Engraulidae and Clupeidae were the most abundant families, accounting to 94.2 % of the total number of fish. A. tricolor was the most abundant species contributing to more than one half of the total numerical abundance, followed in decreasing order by Anchoa januaria (Steindachner, 1879), Sardinella brasiliensis (Steindachner, 1789) and Harengula clupeola (Cuvier, 1829). A. tricolor showed a highly significant positive correlation with salinity, transparency and depth. A. januaria showed the opposite, being inversely correlated to these parameters and directly correlated to temperature. Clupeidae, on the other hand, seems to show a wider distribution in relations to these environmental parameters.
  • Ocorrência e diversidade de ácaros (Acari, Arachnida) associados a Tabebuia roseo-alba (Ridl.) Sand (Bignoniaceae), no município de São José do Rio Preto, São Paulo, Brasil

    Feres, Reinaldo José Fazzio; Bellini, Marcos Roberto; Rossa-Feres, Denise de Cerqueira

    Resumo em Inglês:

    This study reports the mite fauna associated with Tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. Twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. The food habits of the eight remaining species are not known. Besides the great richness, the diversity was small, as consequence of the dominance of Lorryia formosa Cooreman, 1958 and Aculus sp., the most abundant species. These species occurred in the same microhabitat but with seasonal segregation: L. formosa was the most abundant in the dry season, while Aculus sp. occurred only in the rainy season. In August, when the plant lost its leaves, the following species were found in the apical branch structures: Brevipalpus sp. (aff. phoenicis), Cheletogenes sp., Euseius citrifolius Denmark & Muma, 1970, Lorryia formosa, Pronematus sp., and diapause females of Tenuipalponychus tabebuiae Aguilar, Flechtmann & Ochoa, 1991. In September, with leaves growing again, Aceria sp. was the only species on the plant, and its abundance decreased accentuately in October. The richness and the abundance of the mite fauna were not correlated with the temperature or the precipitation. These data suggest that the plant phenology was more important than the climate in the occurrence of species.
  • Aglaenita Spinola: descrição de três novas espécies do Brasil com chave para machos (Hemiptera, Cicadellidae, Neocoelidiinae)

    Chiamolera, Larissa de Bortolli; Cavichioli, Rodney Ramiro

    Resumo em Inglês:

    Three new species of Aglaenita Spinola, 1850 are described: Aglaenita similis sp. nov., Aglaenita elegans sp. nov. and Aglaenita dubia sp. nov. from Amazonas State, Mato Grosso State and Rio de Janeiro State, Brazil, respectively. Illustrations and a key for the species and new occurrences for A. bipunctata Spinola, 1850 are presented. The three new species are similar among them, even so they can be distinguished by the aspect of the male genitalia, mainly by the aedeagus and pygofer.

  • Espécies de Hesperandra (Tavandra) Santos-Silva, com pilosidade abundante no metasterno (Coleoptera, Cerambycidae, Parandrinae)

    Santos-Silva, Antonio

    Resumo em Inglês:

    Parandra scaritoides Thomson, 1861 is removed from synonymy of Hesperandra colombica (White, 1853) and reinstated. Both species are redescribed. New species described from Venezuela: H. solangeae. A key to the three species is added.
  • População e território de forrageamento de uma colônia de Heterotermes tenuis (Hagen) (Isoptera, Rhinotermitidae)

    Camargo-Dietrich, Célia Regina Rodrigues de; Costa-Leonardo, Ana Maria

    Resumo em Inglês:

    Heterotermes tenuis (Hagen, 1858) is a subterranean termite that cause damage in forests, crops and urban areas. The population and foraging territory of an urban colony were determined using triple mark-release-recapture technique. Foraging population was estimated in 134,583 ± 5,803 individuals. The foraging territory encompassed an area of 175,5 m² and the maxim linear foraging distance was 36 m.
  • Histologia das glândulas salivares dos Limacoidea e Milacidae (Gastropoda, Pulmonata)

    Leal-Zanchet, Ana Maria

    Resumo em Inglês:

    The histology of the salivary glands of six species of Limacoidea, Boettgerilla pallens Simroth, 1912, Deroceras laeve (Müller, 1774), Deroceras reticulatum (Müller, 1774), Deroceras rodnae Grossu & Lupu, 1965, Malacolimax tenellus (Müller, 1774) and Lehmannia marginata (Müller, 1774), and a species of Milacidae, Tandonia budapestensis (Hazay, 1881) is comparatively described herein. In the glandular parenchyme four to five secretory cell types are distinguished and characterised, besides a cell type which is probably undifferentiated. The secretory cell types are classified into two groups, mucous and serous cells. Two types of mucous cells and two to three types of serous cells are distinguished. The salivary glands of the herein studied Limacoidea and Milacidae show a duct system composed of intralobular, interlobular and main ducts, each one presenting a characteristic type of epithelial lining. The results are comparatively discussed with the data available in the literature, in order to verify the correspondence between the different cell types described for other Pulmonata.
  • Crescimento e fator de condição na fase juvenil de Farfantepenaeus brasiliensis (Latreille) e F. paulensis (Pérez-Farfante) (Crustacea, Decapoda, Penaeidae) em uma lagoa costeira tropical do Rio de Janeiro, Brasil

    Albertoni, Edélti Faria; Palma-Silva, Cleber; Esteves, Francisco de Assis

    Resumo em Inglês:

    The growth relations of the shrimps Farfantepenaeus brasiliensis (Latreille, 1817) and F. paulensis (Pérez-Farfante, 1967) were evaluated at Imboassica lagoon, Macaé, Rio de Janeiro State, between June 1995 and September 1997, in four periods after events of sandbar opening. This sandbar separated the lagoon from the Atlantic Ocean. Through the evaluation of the weight/length relationships for the two species, significant differences in each interval after the sandbar openings were observed, as much among males and females as among all individuals of the same species. The results indicated that both species presented negative allometric growth in most of the studied occasions. The frequency and abundance of the two species in the lagoon is linked to many factors, among them the season of the sandbar opening, the span of time in which the sandbar remains opened, and the presence of a reproductive stock of adults close to the area when the sandbar is open. Through the analysis of the relative condition factor (Kr), it was verified that usually the conditions inside the lagoon are favorable to the development of both species, with the exception of the occasions when the sandbar opening events happen quickly and close to each other, allowing to conclude that the sandbar openings have an influence on the growth rates and in the general status of the organisms.
  • Morfologia externa de Thyridia psidii cetoides (Rosenberg & Talbot) (Lepidoptera, Nymphalidae, Ithomiinae): II. Tórax e apêndices

    Bizarro, Jorge Manuel Saraiva; Casagrande, Mirna Martins; Mielke, Olaf Hermann Hendrik

    Resumo em Inglês:

    A detailed study of the thoracic external morphology of both sexes of Thyridia psidii cetoides (Rosenberg & Talbot, 1914) is presented. The studied material was obtained at the city's plant nursery "Horto Florestal de Curitiba", Paraná, Brazil; mainly by rearing eggs and larvae collected on Cyphomandra betacea (Canavilles) Sendtner, 1845 (Solanaceae). When possible, all the results obtained were compared with those already available in the literature concerning other Nymphalidae subfamilies morphology (Brassolinae, Morphinae, and Danainae); the most striking feature being the almost totally transparent lateral faces of the thoracic mesoscutum in both sexes.
  • Forrageamento de Melissoptila thoracica Smith (Hymenoptera, Eucerini, Apoidea) em flores de Sida (Malvaceae)

    Silva-Pereira, Viviane da; Alves-dos-Santos, Isabel; Malagodi-Braga, Kátia Sampaio; Leon Contrera, Felipe Andrés

    Resumo em Inglês:

    Foraging activity of a solitary bee species - Melissoptila thoracica Smith, 1854 (Eucerini) - was studied considering its phenology, floral preferences, foraging patterns and pollen's transportation structures. M. thoracica females present a clear preference for flowers of Sida Linnaeus (Malvaceae) in relation to pollen collection. The fidelity for the plant was observed considering foraging flights and analyzing the pollen carried in the females' scopes. The collection of pollen by bees was estimated throughout the counting of remaining grains in the anthers, over one and three visits. Females were examined in scanning electronic microscopy for the analysis of pollen grains in the ventral pilosity and in the scopes. M. thoracica was considered an effective pollinator of Sida flowers.
  • Complex interactions envolving a gall midge Myrciamyia maricaensis Maia (Diptera, Cecidomyiidae), phytophagous modifiers and parasitoids

    Ferraz, Fernando Fortunato Faria; Monteiro, Ricardo Ferreira

    Resumo em Inglês:

    Myrciamyia maricaensis Maia, 1995 (Diptera, Cecidomyiidae) induces a gall in lateral and apical shoots in the plant Myrcia lundiana Kiaersk (Myrtaceae) which is used and modified by two eulophid wasps species. In both cases the gall former species suffer high rate of attack exceeding the importance of parasitoid species as mortality factors. In this study these interactions are described and their effects as mortality of gall former. The intensity of occurrence of the two eulophid species as modifiers and of microhymenopteran parasitoids, and the relative importance of these species as mortality agents of the M. maricaensis larvae is compared. This comparison reveals that two modifiers species found in the gall tissue modification causing the death of the M. maricaensis larva and it is a more important factor of mortality than the cecidomyiid larva parasitism. The fluctuation of the number of each type of gall along the year was monitored in the research field and confirmed in numerical and in synchronic terms of occurrence of the galls; the importance of the species of the gall modifier eulophids, particularly one of these species, as factors of mortality of the M. maricaensis larvae and justified our comparing the relationship between these species and M. maricaensis as similar to the parasitoid-host relationship. The gall shape modification by one of the eulophids allows the occurrence of other inquiline insect species, what means that this gall modification becomes it more heterogeneous and allows the increase of the species richness to the system.
  • Diel and seasonal changes in the macrozooplankton community of a tropical estuary in Northeastern Brazil

    Silva, Tâmara de Almeida e; Neumann-Leitão, Sigrid; Schwamborn, Ralf; Gusmão, Lúcia Maria de Oliveira; Nascimento-Vieira, Dilma Aguiar do

    Resumo em Inglês:

    Studies were carried out to assess the macrozooplankton small-scale temporal and spatial variability at three stations in three hours intervals, during 24 hours in July 1996 (rainy season) and December 1996 (dry season). A plankton net 300µm mesh size was hauled at surface during three minutes. Water samples for salinity, temperature, dissolved oxygen and pH were taken simultaneously with the zooplankton samples. Sixty-five macrozooplankton taxa were registered. Copepoda constituted the most common taxon and comprised 58% of the total zooplankton counts. Brachyuran zoeae, cirripedian larvae, Larvacea (Oikopleura dioica Fol, 1872), and Gastropoda veligers were abundant at some tidal cycles, mainly during the night. Species diversity average was 2.0 bits.ind-1. The mean density ranged from 23 ind.m-3 to 5,201 ind.m-3. The rainy season presented greater numerical abundance. A regular temporal zooplankton cycle was not observed. Instead, there was a large stochastic variation between samples.
  • Last instar larva of Trypoxylon (Trypoxylon) maidli Richards (Hymenoptera, Crabronidae), with biological notes on one nest

    Buys, Sandor Christiano

    Resumo em Inglês:

    The last larval instar and the cocoon of Trypoxylon (Trypoxylon) maidli Richards, 1934 are described. This larva is apparently indistinguishable from that of T. clavicerum exiguum Tsuneki, 1956. They can be distinguished from larvae of other species in the subgenus by the following features: integument of body smooth, sensilla on both sensorial area and labrum, and distinct parietal bands. Notes on nesting site and preys from one nest are presented. Eurycoma insigne (Millidge, 1991) (Linyphiidae) and Argiope argentata (Fabricius, 1775) (Araneidae) are reported as preys.
  • Censo de aves migratórias (Charadriidae, Scolopacidae e Laridae) na Coroa do Avião, Igarassu, Pernambuco, Brasil

    Telino-Júnior, Wallace R.; Azevedo-Júnior, Severino M. de; Lyra-Neves, Rachel M. de

    Resumo em Inglês:

    Thousands of shorebirds and seabirds use the Atlantic route through the northeastern coast of Brazil every year to migrate to South America. In this study was made a census of individuals that uses the Coroa do Avião (7º40'S and 34º50"W), an islet located on the south bar of the Santa Cruz channel on the north coast of Pernambuco state, from May 1993 throughout April 1995 and from August 1996 throughout July 1997. Four species of the family Charadriidae, seven species of the family Scolopacidae, and two species of the family Laridae was observed. The populational peaks match both the period of arrival to the winter season site and the period of departure to the reproduction site. The species considered very frequent were: Charadrius semipalmatus Bonaparte, 1825 and Calidris alba (Pallas, 1764). All the other species were considered rather frequent. There was a strong linear correlation between 1993 and 1994 among Pluvialis squatarola (Linnaeus, 1758) and Arenaria interpres (Linnaeus, 1758); A. interpres and Calidris pusilla (Linnaues, 1766); A. interpres and C. alba; and C. pusilla and C. alba. From 1994 to April 1995 it occured between P. squatarola and C. alba; C. semipalmatus and C. pusilla; C. semipalmatus and C. pusilla; and A. interpres and C. pusilla. From August 1996 throughout July 1997 there was correlation only between P. squatarola and C. pusilla. The obtained results demonstrate the great importance of the Coroa do Avião as a winter season site.
  • Utilização de recursos florais por abelhas (Hymenoptera, Apoidea) em uma área de Caatinga (Itatim, Bahia, Brasil)

    Aguiar, Cândida Maria Lima

    Resumo em Inglês:

    This study was designed to identify important food resource plants used by bee species in a Caatinga area, as well as describe the local patterns of floral use by bees. A total of 1,145 foraging bees, belonging to 60 species, were captured while visiting 50 plant species. Melochia tomentosa L., Sida galheirensis Ulbr., Erythroxylon catingae P. Cowan, and Ziziphus cotinifolia Reiss. were the most frequently visited plants. Melochia tomentosa, Solanum paniculatum L. and S. galheirensis were visited by larger number of bee species. Some oligolectic bees were identified. Apis mellifera Linnaeus, 1758 and Trigona spinipes (Fabricius, 1793) had the largest trophic niche breadth (2.71 and 2.31). The trophic niche overlap was highest (0.52) between Xylocopa grisescens Lepeletier, 1841 and Frieseomelitta silvestrii (Friese, 1902). The low trophic niche overlap between Apis mellifera and native stingless bees seems to be the result of intensive exploration of only a few flower sources by Africanized bees, not frequently visited by meliponids.
  • Composição em tamanho dos peixes (Actinopterygii, Teleostei) de ribeirões da bacia do rio Tibagi, Paraná, Brasil

    Shibatta, Oscar A.; Cheida, Carolina C.

    Resumo em Inglês:

    The standard length of 7610 specimens of 43 species from eight streams of rio Tibagi basin was obtained in order to analyze the means of fish sizes. The higher mean size was observed in Gymnotus carapo Linnaeus, 1758 (165,5 mm) and the smaller, in Phalloceros caudimaculatus (Hensel, 1868) (16,25 mm). Some fish like Acestrorhynchus lacustris (Reinhardt, 1874), Leporinus obtusidens (Valenciennes, 1836), Gymnotus carapo Linneus, 1758 and Synbranchus marmoratus Bloch, 1795 can reach big or medium size when adults but were collected only young, evidencing they use some streams in beginning of life. The mean size of total species was 49,81mm, what shows the small size composition of fishes in the streams. The Kolmogov-Smirnov test comparing the mean size of all streams showed significant similar size both in upstream and downstream regions, independent to the different environmental conditions.
  • Novas espécies e notas sobre Cerambycidae (Coleoptera) do Pará e do nordeste do Brasil

    Galileo, Maria Helena M.; Martins, Ubirajara R.

    Resumo em Inglês:

    Based on material collected by P. Jauffert in Pará and by L. Ianuzzi in Alagoas and Sergipe, four new species are described: Temnopis fasciata sp. nov. (Oemini) and Dihammaphoroides jaufferti sp. nov. (Cleomenini) from Pará. This species breads in branches of Pseudopiptadenia suaveolens (Miq.) J. W. Grimes, Fabaceae. Adetus tuberosus sp. nov. (Apomecynini) and Mimasyngenes lucianae sp. nov. (Desmiphorini) from Alagoas. New records and notes are provided for Neocompsa serrana (Martins, 1962) and Rhopalophora occipitalis Chevrolat, 1859.
  • On two generic homonymies in Cerambycidae (Coleoptera)

    Santos-Silva, Antonio

    Resumo em Inglês:

    Micropsalis Burmeister, 1861 (Prioninae) is preoccupied by Micropsalis Meyer, 1859 (Crustacea). Thus, Apterocaulus Fairmaire, 1864, currently synonym of Micropsalis Burmeister, is reinstated. A historical review about Apterocaulus and Micropsalis Burmeister is added. Microcometes Villiers, 1959 (Disteniinae) is a junior homonym of Microcometes Cienkowsky, 1875 (Protozoa), and Villiersicometes is proposed to replace it.
  • Ecological relationships between feather mites (Acari) and wild birds of Emberizidae (Aves) in a fragment of Atlantic Forest in northeastern Brazil

    Lyra-Neves, Rachel M. de; Farias, Ângela M. Isidro de; Telino-Júnior, Wallace R.

    Resumo em Inglês:

    The objective of this study was to investigate feather mites on birds of the Family Emberizidae, to collect data on the ecological ectoparasite-host relationship and infestation level. A sum of 94 birds of 9 species was captured at the Refúgio Ecológico Charles Darwin, Igarassú, Pernambuco, Brazil, from August 1996 to July 1997. Five genera of mites from the superfamily Analgoidea were identified: Analges Nitzsch, 1818; Mesalgoides Gaud & Atyeo, 1967; Pterodectes Robin, 1877; Proctophyllodes Robin, 1877 and Trouessartia Canestrini, 1899. Among the 94 birds examined, 92 (97,87%) were infested. Regarding the prevalence, it was observed that the genera with higher percentage were, respectively, Pterodectes (88,04%), Proctophyllodes (56,52%) and Trouessartia (45,65%).
  • Crescimento relativo em Uca leptodactyla Rathbun (Crustacea Decapoda Ocypodidae)

    Masunari, Setuko; Swiech-Ayoub, Bianca de Paula

    Resumo em Inglês:

    Relative growth of the male major chela and female abdome was studied in a population of the fiddler crab Uca leptodactyla Rathbun, 1898 from Itapoá, Santa Catarina coast, southern Brazil. Major chela length (CMQ) was measured from 191 males, and abdomen width (LAB) from 128 females. Carapace width (LC) was the reference dimension for both sexes, which ranged from 3.9 to 11.5 mm for males, and from 3.15 to 10.65 mm for females. Males grew bigger than females. Relationship between CMQ and LC showed a transition point at 8.35 mm LC in males, and between LA and LC at 7.10 mm LC in females. Growth was allometrically positive in the early ontogenesis and isometric after the puberal molting for both sexes. Regressions between LC and CMQ in males read as: logCMQ = -0,854536 + 2,19. logLC for empirical points at left of critical point and logCMQ = 0,063047 + 1,24. logLC for those at right. In females, this relation was logLAB = -0,603590 + 1,30. logLC and logLAB = -0,361464 + 1,07. logLC, respectively. These body dimensions were connected with reproductive activity of this species.
  • New species of Temnocephala Blanchard (Platyhelminthes, Temnocephalida) ectosymbiont on Aegla serrana Buckup & Rossi (Crustacea, Anomura) from southern Brazil

    Amato, José Felipe Ribeiro; Amato, Suzana B.; Daudt, Luiz Carlos Campos

    Resumo em Inglês:

    A new species of the genus Temnocephala Blanchard, 1849 is described from southern Brazil, ectosymbiont on Aegla serrana Buckup & Rossi, 1977, an anomuran crustacean, collected in a creek and a reservoir of the highlands in the State of Rio Grande do Sul. All crustaceans examined were positive for this species of Temnocephala and carried eggs in different regions of the ventral side: perioral area, pleural strips, esternal plates, pereiopods and chelipods; to a lesser extent in the dorsal side of the cephalothorax and dorsal side of the uropods; as well as adult and young specimens. The most distinctive characters of the new species are: 1) cyanophilous glands forming an irregular-shaped, grape-like, bunch of approximately 10-15 cells, deeply staining with hematoxylin; 2) shape and size of the cirrus and its introvert section; 3) number, size and distribution of the rhabdite glands and 4) shape and position of the post tentacular, 'excretory' syncytial plates, with the off-centered nephridiopore.
  • Reprodução do peixe-rei, Atherinella brasiliensis (Quoy & Gaimard) (Atheriniformes, Atherinidae), em uma planície de maré adjacente à gamboa do Baguaçu, Baía de Paranaguá, Paraná, Brasil

    Favaro, Luís Fernando; Lopes, Sabine de C. G.; Spach, Henry Louis

    Resumo em Inglês:

    The present study investigated the reproductive biology of silverside, Atherinella brasiliensis (Quoy & Gaimard, 1825) in a tidal flat of Paranaguá Bay, littoral of Paraná State, Brazil. Fish were captured monthly from November 1998 to October 1999 by the mean of a seine-net. For each individual, total body length, total weight, sex, and gonadal weight were recorded. Gonadal development stages were also defined based on the histological examination of the ovaries and on the visual aspects of the testes. It was defined that the reproductive period of A. brasiliensis extends from June to December, based on he analyses of individual gonadosomatic index (GSI) values distribution in relation to the sampling periods, on the monthly variation of the GSI mean values (Curve of Maturation), both for males and females, and on the monthly variation of the relative frequencies of the female maturation stages. During this period, matured, partially spawned and spent females were found in higher frequencies in comparison to the other months. The sizes at first maturation were defined as 7,61cm and 6,92cm for females and males, respectively.

  • Frugivoria em morcegos (Mammalia, Chiroptera) no Parque Estadual Intervales, sudeste do Brasil

    Passos, Fernando C.; Silva, Wesley R.; Pedro, Wagner A.; Bonin, Marcela R.

    Resumo em Inglês:

    This study was carried out at the Intervales State Park, an Atlantic Rain Forest area in Southeastern Brazil. Bats were monthly mist netted over a full year, and fecal samples were collected for dietary analysis. The seeds found in each sample were identified in the laboratory under a stereoscopic microscope by comparison with seeds taken from ripe fruits collected in the study area. Three hundred and seventy one bats were collected, of which 316 (85.2%) were frugivorous. The total number of fecal samples with seeds and/or pulp was 121. Sturnira lilium (E. Geoffroy, 1810) was the most abundant species in the study area (n = 157 captures) and Solanaceae fruits accounted for 78.5% of the fecal samples with seeds (n = 56). Artibeus fimbriatus Gray, 1838 (n = 21 samples) fed mostly on Cecropiaceae (38%) and Moraceae fruits (24%), and Artibeus lituratus (Olfers, 1818) (n = 7 samples) on Cecropiaceae (57%) and Moraceae (29%). Carollia perspicillata (Linnaeus, 1758) (n = 16 samples) fed mostly on Piperaceae fruits (56,3%), but Solanaceae (31,3%) and Rosaceae seeds (12,5%) were also found in feces. Overall, seeds found in bat feces belong to eight plant families: Solanaceae (n = 67 samples); Cecropiaceae (n = 14); Piperaceae (n = 14); Moraceae (n = 8); Rosaceae (n = 3); Cucurbitaceae (n = 3); Cluseaceae (n = 1), and Araceae (n = 1). The close association of different bat species with fruits of certain plant families and genus may be related to a possible mechanism of resource partitioning that shapes the structure of the community.
  • Fruit removal of a wild tomato, Solanum granulosoleprosum Dunal (Solanaceae), by birds, bats and non-flying mammals in an urban Brazilian environment

    Cáceres, Nilton Carlos; Moura, Maurício Osvaldo

    Resumo em Inglês:

    A study of removal of fruits of the wild tomato, Solanum granulosoleprosum Dunal (N = 5 plants), by vertebrates was carried out in an urban environment of southern Brazil from January to May 1997 and February 1998. To verify diurnal and nocturnal removals, fruits were counted in several fruit bunches, being classified by size and color. Diurnal observations were made on plants to verify bird removal. A mist net was placed among the plants from the evening to 23:00 h to verify bat consumption. Live traps baited with S. granulosoleprosum fruits were placed on the ground among plants to verify terrestrial removers. On average it was found two ripe fruits available per bunch/day, but unripe, small, fruits were dominant (70%). Nocturnal mammals and birds-diurnal mammals partitioned fruits similarly. Bats removing fruits were Artibeus lituratus (Olfers, 1818), Pygoderma bilabiatum (Wagner, 1843) and Sturnira lilium (E. Geoffroy, 1810). Birds were Saltator similis Lafresnaye & d'Orbigny, 1837 and Thraupis sayaca (Linnaeus, 1766). Terrestrial mammals were a marsupial and three rodent species. Except for rodents, these vertebrates must be promoting the seed dispersal of S. granulosoleprosum seeds in disturbed mixed forests of southern Brazil.
  • Redescrição de Choeradoplana iheringi Graff (Platyhelminthes, Tricladida, Terricola)

    Leal-Zanchet, Ana Maria; Souza, Simone Aparecida de

    Resumo em Inglês:

    Choeradoplana iheringi Graff, 1899 was described on specimens proceeding from Taquara, Rio Grande do Sul, Brazil. Afterwards, RIESTER (1938), MARCUS (1951) and FROEHLICH (1955) analyzed specimens from southeast Brazil, identifying them as C. iheringi. In this study samples of C. iheringi from São Francisco de Paula, a site next to the type-locality, and specimens from the Southeast (Salesópolis, state of São Paulo), are comparatively analyzed. It was observed that the external morphology of the specimens from São Francisco de Paula and from Salesópolis is concordant with the original description of C. iheringi, as well as that by RIESTER (1938) and MARCUS (1951). The pharynx is better designated as bell-form, and not collar-form as described by GRAFF (1899). The copulatory apparatus is characterized by the presence of an intra-bulbar prostatic vesicle, consisting of two regions, an ental tubular one and an ectal one of variable shape; absence of penis papilla; and a male atrium, elongated and highlypleated. The copulatory apparatus of C. iheringi described by GRAFF shows some anatomical characteristics that distinguish it from the material studied by other authors, and from the material analyzed here. Some anatomical and histological characters of the copulatory apparatus distinguish the specimens from São Francisco de Paula from those of Salesópolis which are assigned to populational and/or physiological differences. The specimens from São Francisco de Paula and Salesópolis, as well as those analyzed by RIESTER (1938) and MARCUS (1951), are confirmed as C. iheringi Graff, 1899.

    The Hepatus pudibundus (Herbst, 1785) juvenile development was studied in laboratory, under the morphological and systematical stand points. The eight early juvenile stages were obtained from larvae hatched from eggs of two ovigerous females, collected at the northern coast of the State of São Paulo, Brazil. The experiments were carried out in a climatically controlled room at 25 ± 1°C, and steady saltness of 34‰. The youngs were maintened individually and food consisted of Artemia sp. nauplii and fragments of fish muscle.The first juvenile stage were particulary drawn and described. For the remaining juvenile stages the most representative frameworks were picked out, which allowed the characterization of the first eight stages. According to juvenile morphology studies, it was noted that secondary sexual characters differentation begins from the third stage.
  • Comparative morphology of Cymothoa spp.(Isopoda, Cymothoidae) from Brazilian fishes, with the description of Cymothoa catarinensis sp. nov. and redescriptions of C. excisa Perty and C. oestrum (Linnaeus)

    Thatcher, Vernon E.; Silva, Jayme de Loyola e; Jost, Glauco F.; Souza-Conceição, José M.

    Resumo em Inglês:

    Cymothoa catarinensis sp. nov. collected at Camboriú, Santa Catarina State, Brazil is described. The new species is of small size, has a cephalon that is little immersed in pereonite 1, anterolateral angles of pereonite 1 that reach or surpass the eyes and a pleon that is deeply immersed in pereonite 7. The pleopods of the new species have small, lobular accessory gills projecting from the bases. Cymothoa excisa Perty, 1830, and Cymothoa oestrum (Linnaeus, 1758) are redescribed. Both are of large size (25-35 mm in length). C. excisa has pointed anterolateral margins of pereonite 1 that reach or surpass the eyes. This species also has trilaminate pleopods in the female and bilaminate pleopods in the male. C. oestrum has rounded anterolateral margins of pereonite 1 and no visible eyes. This is the first time the latter species has been reported from Brazil. These three species are compared to four others that have been reported from Brazilian waters, namely: C. liannae Sartor & Pires, 1988; C. brasiliensis, C. gerris and C. ianuarii, all described by Schiödte & Meinert, 1884. A key is provided to aid in the separation of the Brazilian species of Cymothoa.
  • Nova espécie de Hyla Laurenti do grupo de H. microcephala Cope (Amphibia, Anura, Hylidae) do nordeste do Brasil

    Carvalho-e-Silva, Sergio Potsch; Carvalho-e-Silva, Ana M. P. Telles; Izecksohn, Eugenio

    Resumo em Inglês:

    A new species, attributed to the group of Hyla microcephala Cope, 1886, is described. The new species is close to H. bipunctata Spix, 1824, and it is found in Quebrangulo, State of Alagoas, in Northeastern Brazil. The eggs and larvae are also described and some ecological information is added. The new species is compared with other species of the same group, and with species of closely related groups that occur in syntopy. With H. bipunctata, it shares the general form of the body, the yellow ventral coloration and the orange color of the thighs, but it is distinguished by the dorsal Paris-green coloration (beige in H. bipunctata), absence of a dorsal pattern, light red thighs, and ornamentation of the upper lip with two or three yellow stains instead of the characteristic aureolate of H. bipunctata. With H. elegans Wied-Neuwied, 1824, it also shares the general form of the body and the ventral and the thighs coloration, but it is distinguished by the smaller size, absence of a dorsal pattern and light red thighs. From H. oliveirai Bokermann, 1963, the new species is distinguished by the dorsal coloration, the ornamentation of the upper lip and larger size. From H. branneri Cochran, 1948, it differs by the presence of the stains in the upper lip (just one in H. branneri), absence of the dorsal pattern and green dorsal coloration, which is more intense. The tadpole of the new species is provided.
  • First record of Charadrius melodus Ord (Aves Charadriiformes) in Brazil
