A arara-azul-de-Lear, Anodorhynchus leari Bonaparte, 1856 Zoologia
Sick,Helmut; Gonzaga,Luiz Pedreira; Teixeira,Dante Martins.
The case of the Indigo, or Lear's Macaw, Anodorhynchus leari, is unique in South American ornithology. The species, although described more than 100 years ago, was known only through very few living specimens, which entered occasionally the bird trade, without any indication of their origins. It was presumed "probably some part of Brazil" (Salvadori, 1891). The last speculation was that it was unlikely, though not impossible, that the Indigo Macaw might not be an independem species, but rather, a hybrid between the two other well known blue macaws, Anodorhynchus hyacinthinus and A. glaucus (Voous, 1965).

A associação entre Crepidula aculeata (Gastropoda, Calyptraeidae) a alga calcárea Amphiroa beauvoisii, na Baía de Santos, São Paulo, Brasil Zoologia
Masunari,Setuko.
Association Crepidula aculeata - Amphiroa beauvoisii. Population study of Crepidula aculeata Gmelin, 1791) (Gastropoda Calyptraeidae) and analysis of protocooperative association between the mollusc and the alga were carried out in the phytal of calcareous alga Amphiroa beauvoisii Lamouroux, 1816 at Ilha das Palmas, Santos Bay (24º00'S - 46º19'W). Samples were collected at three sites of different degree of water movement in the intertidal zone and sublittoral fringe during 1975 and 1976. From 93,916 organisms belonging to 172 species, 5,331 were Crepidula, the most abundant among sessile species. Also, Crepidula constitutes a substratum to attachment of Amphiroa, accounting for 30% of total phytal area. There was a positive correlation between the growth...

A brief note on the sleeping habits of the giant anteater - Myrmecophaga tridactyla Linnaeus (Xenarthra, Myrmecophagidae) Zoologia
Medri,Ísis Meri; Mourão,Guilherme.
The scientific literature on giant anteaters states that the animal sleeps with its tail folded over its body to conserve body temperature. However, observations of this species in natural habitats indicate variations in this behavior, depending on the ambient temperature.

A cladistic analysis of the genera of Macrothricidae Norman & Brady (Crustacea, Cladocera, Radopoda) Zoologia
Elmoor-Loureiro,Lourdes M. A..
A cladistic analysis of the genera of the Macrothricidae (Crustacea, Cladocera, Radopoda) was performed based on 36 morphological characters, and including 15 terminal taxa (three as outgroups). The single tree obtained from this analysis supported the monophyly of Macrothricidae and Macrothricinae. The group called as "non-Macrothricinae" was indicated as paraphyletic. Neothricidae was also not supported.

A comunidade de macroartrópodos edáficos em uma plantação de Coffea robusta Linden (Rubiaceae) e em uma floresta primária em Linhares, Espírito Santo, Brasil Zoologia
Pellens,Roseli; Garay,Irene.
The composition and structure of the edaphic macroarthropod community of these two sites were comparatively studied. The results obtained show that the total densities in the plantation of C. robusta can be higher than in the primary forest. Even though, contrarily to the observed in the forest, this community is characterized by the dominance of some non social groups and by the concentration of most of its individuals in the litter layers. As a consequence, the entire community is more susceptible to seasonal variations in density. Thus, these results emphasize the importance of the leaf litter in providing habitat, food as well as more stable microclimatic conditions for the macroarthropods community. For this reason it is importam to avoid any kind of...

A condição das coxas anteriores, do meso-catepímero e do meso-catepisterno dos Tabanidae (Diptera) e sua possível importância na classificação Zoologia
Bernardi,Nelson.
The condition of certain neglected structures and their possible importance to the classification of the family Tabanidae are studied. The front coxae are considered as belonging to two types: 1) short and robust; 2) long and slender. The posterior edge of the meso-katepimeron presents two conditions: 1) without projection, 2) with backward projection. Similar conditions are found in the meso-Katepisternum, but with intermediate conditions. These characters are discussed in relation to the system proposed for the family by Mackerras. Conditions 1 and 2 of the former two structures separate, respectively, the Pangoniinae and Scepsidinae from the Chrysopsinae and Tabaninae. Condition 2 of the third structure seems to be developing independently in different...

A dieta dos morcegos frugívoros (Mammalia, Chiroptera, Phyllostomidae) de um pequeno remanescente de Floresta Estacionai Semidecidual do sul do Brasil Zoologia
Mikich,Sandra Bos.
The diet of some leaf-nosed frugivorous bats - Artibeus Leach, 1821, Carollia perspicillata (Linnaeus, 1758) and Sturnira lilium (e. Geoffroy, 1810) - was studied for nine consecutive months through faecal analysis of individuais captured with mist-nets in a small forest remnant of Paraná state, Brazil. The analysis revealed that Artibeus spp. exhibited preference for fruits of Ficus spp. and Carollia perspicillata for those of Piper spp., which is in accordance with the results of previous studies. But contrary to what was expected, fruit of Solanum spp. were not found for the diet of Sturnira lilium in spite of their high availabilily (16 species) in the study area and their known relationship with this bat genus. The species of consumed fruit belonged...

A extração de corrupto, Callichirus major (Say) (Crustacea, Thalassinidea), para uso como isca em praias do litoral do Paraná: as populações exploradas Zoologia
Souza,José R. B.; Borzone,Carlos A..
A recreational fishery that use ghost-shrimp as bait was evaluated along 11 km of a sandy beach of Paraná State. The beach was divided in five sectors and samples were obtained along a transect extended on the middle of each sector, after and before months of major extractive activity. The highest densities were found in beaches with well select very fine sands and gentle slope. The density decreased only at the sector that presented greater extractive activity. In this sector, the smallest mean modal size was detected too. The total standing stock of the whole area was 2,486,250 individuals before summer's months, with a mean density of de 4.48 ind.m-2. Annual fishing effort represented nearly 10 % of total standing stock.

A field comparison of two capture-mark-recapture estimators of small mammal populations Zoologia
Gentile,Rosana; Fernandez,Fernando A.S.
The results obtained by two estimators of population sizes, MNKA and Mh, were compared for four species of small mammmals - Didelphis aurita Wied, 1826, Philander frenata (Olfers, 1818), Nectomys squamipes (Brants, 1827) and Akodon cursor (Winge, 1887) - during a long-term population study. The MNKA estimator consistently underestimated the population sizes in relation to Mh. On the other, the probabilistic estimator Mh, which reduces bias through the jackknife technique, could not be used in all cases as its assumptions were not always met. Correction factors between the estimates obtained by the two methods were calculated for the last three species, for which catchability did not vary significantly in time and that presented positive correlation between...

A formação dos oostegitos em Porcellio dilatatus Brandt (Crustácea, Isopoda, Oniscidea) em laboratório Zoologia
Loyola e Silva,Jayme de; Coraiola,Maria Aparecida Sídor.
Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred...

A incubação de ovos e larvas em Genidens genidens (Valenciennes) (Siluriformes, Ariidae) da Baía de Guaratuba, Paraná, Brasil Zoologia
Chaves,Paulo de Tarso da C.
At Guaraluba bay, the catfish Genidens genidens shows incubating behavior during the summer months. The larvae are either less or heavier than the eggs, and their stomach analysis confirms the exogenous leeding during incubation. Embryos sizes can increase to 59mm in total lenght and 2,8g in total weight, including the yolksac. It was observed that the largest larvae are guarded by the largest adults, and that the embryo size is similar among individuals from the same adult.

A key to the Afrotropical genera of Muscidae (Diptera) Zoologia
Couri,Márcia S..
A key to 57 of the 58 Afrotropical Muscidae (Diptera) genera is given. The previous Catalogue of Afrotropical Diptera published about 25 years ago by Adrian C. Pont was used as a taxonomic guide, to which the more recently synonyms and taxonomic changes were updated. For each genus, geographical distribution and number of valid species in this region are also included. Some morphological diagnostic characters are illustrated in order to help the use of the key.

A lagarta de Cerconota achatina (Zeller) (Lepidoptera, Oecophoridae, Stenomatinae): biologia e ocorrência em plantas hospedeiras do gênero Byrsonima Rich (Malpighiaceae) Zoologia
Andrade,I; Diniz,Ivone R; Morais,H.C.
Caterpillars of Cerconota achatina (Zeller, 1855) feed on lhe leaves of Byrsonima Rich in cerrado (savanna) of Brasília (Distrito Federal). They build shelters by tying leaves together with silk and frass. Within the leaf shelters the caterpillars form a tube of silk in which they feed. develop and pupate. In the laboratory the pupal stage is 14,4 days (sd=8,6: n=46). It was not possible to determine the age or numbers of instars of caterpillars in the wild. Of 93 caterpillars collected. 60% were feeding on B. cocclohifolia (Spr.) Kunth, 25% on B. crassa Nied. and 15% on B. verbascifolia [Rich. ex] Adr. & Juss. These numbers suggest a preference for B. coccolobifolia. Caterpillars of all size were found in every month of the year which suggest...

Suriani,Ana L.; França,Roberta S.; Rocha,Odete.
Este trabalho analisa a composição de espécies, a densidade e a distribuição espacial e temporal da malacofauna bentônica em três represas do médio rio Tietê. As coletas foram realizadas em dois períodos climáticos, o chuvoso em novembro de 2002 e o seco em agosto de 2003, amostrando-se três porções em cada represa (superior, mediana e barragem) e seguindo uma varredura com seis pontos amostrais em cada transecto. Os dados limnológicos obtidos evidenciaram que as represas do médio rio Tietê encontram-se eutrofizadas com elevadas concentrações de nutrientes (totais e dissolvidos). Foram registradas oito espécies de moluscos sendo seis nativas e duas exóticas. Destas, a espécie dominante foi o molusco exótico e invasor Melanoides tuberculata (Müller, 1774),...

A morphometric analysis of Eunice Cuvier (Annelida, Polychaeta) species Zoologia
Costa-Paiva,Elisa M.; Paiva,Paulo C..
Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E.fucata, E.insularis, E. cf. ornata, E.rubra, and Eunice sp. was compared using traditional morphometric analysis of 16 measured variables. After removing the size-effect, a Canonical Variates Analysis applied to morphometric variables was able to discriminate all species. In CV1 two major groups of species were discriminated: E.fucata/E.insularis and E. cf. ornata/E.rubra/Eunice sp. CV2 strongly discriminated all species, with E....
