Neocorbicula limosa (Maton, 1811) is the only species of that South American genus that occurs in the hydrographic basins of Rio Grande do Sul State, Brazil. Seasonal quantitative collections between 1995 and 1996 in the lake Guaiba were accomplished, with the aim to know the reproductive dynamics and environmental preferences of populations of N. limosa. A substratum constituted by medium to coarse sands at an 'average depth around 2m shown to be favorable to installation of population of N. limosa. The largest population density (2.496 ind./m²) was registered in summer. Embryos at various development phases were registered inside individuals. The shell sizes of these individuals started from 8mm in length. The embryo's size could reach ¼ of the shell-mother's size, and their liberation occurs through the rupture of the gills.Resumo em Inglês:
Four places in Latin-America have Melipona Illiger, 1806 beekeeping: Mexico, with M. beecheii Bennet, 1831; Northeast Brasil, with M. scutellaris Latreille, 1811; Maranhão State (Brazil) with M. compressipes fasciculata Smith, 1854; Venezuela, in her coast, with M. favosa (Fabricius, 1798). Natural colonies of M. compressipes fasciculata occupied tree holes ranging from 6,5 to 24 1. The average honey production of 60 colonies in hives with capacity of 50.2 1, 41.0, 30.2, 16.5 and 6.2 were respectively 8.4, 6.5, 5.5, 3.3 and 2.0 Kg. Due to lack of bee flowers within the city limits, hives with a volume of 27 1 (30x30x30 cm) were used successfully in our future experiments with M. compressipes fasciculata instead of the ideal size of 40 to 50 liters, since the intense use of biological material did not allow the colonies to reach large sizes.Resumo em Inglês:

The present work is the first report of Dardanus venosus (H. Milne Edwards, 1848) in São Paulo State and extends the range of this species in the western Atlantic farther to the south in the Brazilian region. A total of twenty two males (mean shield length: 7.56 ± 1.62 mm, 4.7 to 10.9 mm), and fifteen females (7.25 ± 2.53 mm, 4.3 to 14.5 mm) were collected in 1987, 1998, 1999 and 2000 by scuba diving from three areas of Anchieta Island (23º33'S, 45º05'W) in the Ubatuba region, and south of São Sebastião Island (23º57.8'S, 45º16'W), northern coast of São Paulo State. No ovigerous females were captured during the study period. Shells of eleven gastropod species were occupied by D. venosus: Astraea latispina (Philippi, 1844), A. olfersii (Philippi, 1846), A. phoebia Roding 1798, Calliostoma bullisi Clench & Turner 1960, Chicoreus tenuivaricosus (Dautzenberg, 1927), Cymatium parthenopeum (von Salis, 1793), Olivancillaria urceus (Röding, 1798), Phalium granulation (Born, 1778), Stramonita haemastoma (Linnaeus, 1767), Strombus pugilis Linnaeus, 1758 and Zidona dufresnei (Donovan, 1823).Resumo em Inglês:
Females of Orphulella punctata (de Geer, 1794) were captured in the field and kept in cages with food and boxes filled with moist soil for oviposition. The eggs, macerated with 0,85% saline solution and centrifugated, were used as the immunizing antigen for obtention of the specific antiserum (AS-O). Rabbits were immunized by the linphonodule injection method with two injections of this antigen, with an interval of 15 days between the 1st and 2nd inoculations. Serological tests were performed using double diffusion in agar gel with homologous and heterologous antigens. Specific serological reactions were obtained 14 days after the 1st inoculation. The antiserum of the 30th day gave 5, 2-4 and 1-4 precipitation lines respectively with eggs, female and male antigen. Such differences can be attributed to the high specificity of AS-O. Positive reaction was observed with arachnids and mirmeleontids captured in the field, indicating the predation on O. punctata.Resumo em Inglês:
Foregut in D. hominis (Linnaeus Jr., 1781) as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the foregut. Metamoiphosis begins at the end of the larval period with signs of nuclear degeneration of all the polytenic cells, as well as the increase in number of the imaginal disk ones. The oesophagic portion intussuscepted into the cardia, everts; its cells suffer apoptosis and are replaced by the new cells growing from the imaginal disk. The external layer cells also degenerate and are pinched off into the lumen of the very anterior portion of the midgut. The newly formed oesophagus intussuscepts "de novo" to form the two internal layers of the adult cardia. At the same time the midgut regenerative cells grow anteriorly to form the new external layer of the adult cardia.Resumo em Inglês:
Dermatobia hominis (Linnaeus, 1781) midgut is internally lined by an epithelium of polytenic cells, some low others prismatic with well developed brush border. Their apical portion are enlarged by secretory vesicles, forming button-like structures that are pinched off to the lumen, some accompained by the nucleus characterizing apocrine and holocrine secretions. This epithelium is gradually renewed by small, non polytenic regenerative cells, found scattered at its basal portion. At the end of the third instar the metamorphosis begins. The epithelial cells present signs of degeneration and at the first day of pupation the regenerative cells increase in number. By the 5th day of pupation these regenerative cells, besides being increased in number, differentiate themselves into two layers: one similar to the dense conective tissue that sustainning the larval epithelium is pinched off to the midgut lumen forming the "yellow bodies"; the other, develops right under it as the imaginal epitelium. The disorganized muscles bundles of the midgut wall, are invaded by phagocytes. At the end of pupation the midgut has a low prismatic epithelium with brush-border. In the adult, the torax portion of the midgut has prismatic homogeneously basophilic epithelium while in the abdominal portion the epithelium is made of high prismatic cells full of small vacuoles. The larval midgut epithelium suffers programmed cell death non compatible with apoptose. During the metamorphosis the midgut lenght diminishes from 31mm in the larva to 14mm in the adult.Resumo em Inglês:
The present paper deals with the changes on ultrastructural features of the follicular cells along the growth of the oocyte of Pseudotylosurus microps (Gunther, 1868). The epithelium pass from single squamous to pseudostratified and finally cylindric. Remarkable are the changes in the nuclear shapes, the increasing amount of rough endoplasmic reticulum and the formation of large lipid deposits in the follicular cells by the end of vitellogenic phase. Very peculiar intercellular deposits forms between the perinucleolar and vitellogenic phase of oocyte maturation. Although largely referred to in the specialized literature, our attempts to correlate the follicular cells changes with the formation of the oocyte envelopes or even with an endocrine function are not supported by conclusive evidences in the present paper.Resumo em Inglês:

The domestic dove Columba livia (Gmelin, 1789) is a species well adapted to Brazil and the study of its reproductive biology is part of a broad research project on birds. This essay describes the morphological aspects of the cloaca of female Columba livia, describing compartments lengthwise starting from the head such as the coprodeo, urodeo and proctodeo limited by mucosal folds. Each compartment of the cloaca presents its own morphological characteristics which differ one from the other in form, height and position of mucosal projections, kinds of tissues, presence and histological aspects of glands, presence of lymphonodus. The rectum opens into the coprodeo, the ureter opens into the oviduct and the cloacal sac opening into the proctodeo. Histochemical studies have shown the presence of glycoproteins in tissue cells and gland cells on the three segments of the cloaca.Resumo em Inglês:
The length-weight relationship of populations of white croaker Micropogonias furnieri (Desmarest, 1823) in the Sepetiba Bay (22º54'-23º04'S; 43º34'-44º10'W), were assessed. It aims to contribute to the knowledge of the biometrics and to estimate the biomass of this very abundant fishery resource in the Bay. Fishes sampled, in both trawling beach seine, sampling programme, from October 1998 to May 1999 were analyzed. The equation found was W = 0.00000942 L2.99 fom the natural logaritmized transformation of the raw data, through ordinary least square equation = In W = -11.57 + 2.996 In L (r=0.99). The condition factor was relatively high compared with coastal population from Southeast Brazil, probably due to in this study both males and females from juvenile and adult were considered, while in coastal areas, only adult female were analyzed. The alometry coefficient (θ), on the other hand, is very similar to the coastal Southeast Brazil population, but differed from Northeast and South Brazil populations.Resumo em Inglês:

The Caribbean skate Dipturus teevani (Bigelow & Schroeder, 1951) is recorded for the first time from Brazilian waters. The specimen was collected in the continental slope off Bahia State. With this record, four species of Dipturus Rafinesque, 1810 are known from Brazil: D. chilensis (Guichenot, 1848), D. leptocauda (Kreft & Stehmann, 1975), D. trachyderma (Krefft & Stehmann, 1975) and D. teevani (Bigelow & Schroeder, 1951). They are typical inhabitants of deep waters between the outer shelf edge (195-200m) and the slope (more than 500m). Although morphologically conservative, the species of Dipturus can be distinguished from each other by the number of dorsal and nuchal thorns, the number of caudal thorns, dorsal and ventral spinulation and specific total length. An identification key for the species of Dipturus recorded from Brazil is presented.Resumo em Inglês:
Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767) snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 days. In the experiments, the snails moved on rock by continuous, direct, ditaxic, alternate undulations of the foot sole but on submerged sand they used slower arrhythmic discontinuous contractions of the foot sole. They switched between modes of locomotion in response to the type and topography of the substrate and possibly to water dynamics. In nature, snails moved between rocks forming aggregations where they oviposited. This may have masked other causes of movement, such as availability of prey. Most snails burrowed into the sand when the rocks became exposed during low tides. Further experiments are needed to explicitly address the possible causes of movements among rocks and burial.Resumo em Inglês:
The purpose of the present study is to examine the population structure and the breeding period of Pachycheles monilifer (Dana, 1852) inhabiting sabellariid worm reefs in the littoral of São Paulo State coast. The specimens were obtained at 2-month intervals from September/94 to July/95. The study sites were located at the rocky shores of Tenorio and Paranapuã Beaches. Individuals sampled showed a total averaged 4.4 ± 1.4 mm carapace length. Ovigerous females were more frequent in September. Despite clear differences regarding the arrangement of these sabellariid colonies, they are extremely important to the establishment and maintenance of P. monilifer.Resumo em Inglês:
The beetles are a useful group for studies on trophic structure of communities, mainly in forested areas. These kind of studies are based on food habits of species groups. The different terms applied to nomminated these groups (trophic category, ecologic group, trophic group, guild, trophic guild) are discussed. The term trophic group, a natural unity, is proposed to form a group of species with the same food habits, not considering the trophic level. The guild, an artificial unity, is recognized as an important tool to group organisms group that use the same resources as defined by the investigator (Hawkins & MacMaiion, 1989; Simberloff & Dayan 1991; Wilson 1999). The known alimentary habits of Coleoptera are classified in five trophic groups - herbivores, algivores, fungívores, detrivores and carnivores. Within each trophic group, subgroups are recognized. The subgroup are in a lower hierarchic level and are defined by morphological (herbivores), taxonomic (fungivores) atributes of the food, by the food origin (detrivores) and by the way that the food is obtained (carnivores). A food resource diagram showing connections among the trophic groups, based on consumer-consumed (predator-prey) relations, is presented.Resumo em Inglês:
