ANÁLISE DA FROTA PESQUEIRA ARTESANAL DA COMUNIDADE DA RAPOSA, SÃO LUIS, MA

Entre novembro de 1987 e agosto de 1988, realizou-se um censo da frota artesanal da Rapôsa, principal comunidade pesqueira do litoral maranhense. Esta frota está composta por 221 embarcações) das quais 186 operam na pesca. É uma frota estruturalmente heterogênea, segundo o tipo de casco e o tipo de propulsão. As variações dos diferentes tipos, são representáveis pelo comprimento do barco. Definiram-se 4 estratos dentro desta frota, que são: 1. Bianas abertas com vela biana; 2. 3iana aberta com vela curicaca; 3. Guanas fechadas e botes com potência de motor menor de 40 HP e 4. Botes com mais de 40 HP. As possíveis medidas de poder de pesca são o comprimento da embarcação e o comprimento de rede, as quais servirão de base para avaliação dos recursos pesqueiros explorados pela frota analisada, principalmente Scomberomorus brasiliensis, Macrodon ancylodone Cynoscion acoupa.

Prey consumed by Guiana dolphin Sotalia guianensis (Cetacea, Delphinidae) and franciscana dolphin Pontoporia blainvillei (Cetacea, Pontoporiidae) in an estuarine environment in southern Brazil

The present study provides information about the diet of sympatric populations of small cetaceans in the Babitonga Bay estuary. This is the first study on the diet of these species in direct sympatry. The stomach contents of seven Guiana dolphins Sotalia guianensis and eight franciscanas Pontoporia blainvillei were analyzed. The prey of both cetaceans was mostly teleost fishes, followed by cephalopods. We identified 13 teleost fishes as part of the diet of the franciscanas, and 20 as part of the diet of Guiana dolphins. Lolliguncula brevis was the only cephalopod recorded, and was the most important prey for both cetaceans. Stellifer rastrifer and Gobionellus oceanicus were also important for franciscana, so as Mugil curema and Micropogonias furnieri were important for Guiana dolphins. Stellifer rastrifer and Cetengraulis edentulus were the fishes with the highest frequency of occurrence for franciscana (50%), while Achirus lineatus, C. edentulus, S. brasiliensis, Cynoscion leiarchus, M. furnieri, M. curema, Diapterus rhombeus, Eugerres brasilianus and G. oceanicus showed 28.6% of frequency of occurrence for Guiana dolphins. Franciscanas captured greater cephalopods than the Guiana dolphins in both total length (z= -3.38; n= 40; p< 0.05) and biomass (z = -2.46; n = 40; p<0.05). All of the prey species identified occur inside the estuary, which represents a safe habitat against predators and food availability, reinforcing the importance of the Babitonga Bay for these cetacean populations.

The diet of the South American sea lion (Otaria flavescens) at Río Negro, Patagonia, Argentina, during the winter-spring period

The South American sea lion, Otaria flavescens (Shaw, 1800) population is steadily expanding along the Patagonian coast of Argentina in the last decades. However, little is known about the feeding ecology of the species in the area. The aim of this study was to analyze the food habits of O. flavescens from 91 scats collected at Río Negro province, during the winter and spring of 2005. Fish occurred in 96% of scats containing prey remains, followed by cephalopods (26%). Raneya brasiliensis (Kaup, 1856) was the most frequent and abundant species occurring in 58.6% of samples and constituting almost 50% of fish predated. Second in importance were Porichthys porosissimus (Cuvier, 1829) and Cynoscion guatucupa (Cuvier, 1830) in terms of occurrence (%FO 20.7) and numbers (29.6%) respectively. The squid Loligo gahi (d'Orbigny, 1835) was the most frequent cephalopod prey (42.1%), whereas Octopus tehuelchus (d'Orbigny, 1834) was the most abundant (77%). The higher amount and diversity of prey found in the spring in comparison with the winter season might be related to a higher feeding activity of seals or to a seasonal increase in food availability in the area.

Terceira contribuicäo ao conhecimento do gênero Archytas Jaennicke, 1867: (Diptera, Tachinidae)

Twelve species of the genus Archytas Jennicke, 1867, eight of which described as new are studied and figured in detail. Definitions of the species are based mainly on characters of male genitalia. The male genital characters are the most significant for separation of the species and most demonstrative of their affinities. By examining a long series of species of this genus we came to the conclusion that the presence of one pair of median marginal bristles on the third abdominal tergite seems to be characteristic of the genus. This caracter apparently so important, is not however considered fundamental. The most significant example is found in Archytas lenkoi sp. n. and Archytas vexor Curran, 1928. In A. lenkoi we can find one or two pairs or thay may, less frquently, be absent. In A. vexor these bristles are lacking. The shape of the male copulatory apparatus of Jurinia nitidiventris Curran, 1928 refered to by CURRAN in his "Revision of Archytas", is not characteristic of any species of the group and so, is not considered in this paper. To help in the identification, the species studied here are divided into groups. The analis group" includes: A. apicifer (Walker, 1894), A. californiae (Walker, 1856), A. nivalis Curran, 1928, a. giacomellii (Blanchard, 1941), A. basifulvus (Walker, 1849), A. incasanus Townsend, 1912 and A. cirphis Curran, 1927. The identification of members of these group is extremely difficult owing both to their similarity in colour pattern and to their variability. They all have black testaceous or dark brown abdomen, the last segment pale or brownish pollinose; second segment without bristles; third with a pair of strong marginals, fourth and fifth with two rows of discals on apical third. The final determination often rests upon the structure of the male copulatory apparatus. Fortunately in this group, many of the forcipes superiores and palpi genitalium are strikingly different from one another. The "zikani group" includes: A. zikani sp. n., A seabrai sp. n., A. duckei sp. n. and A. vernalis Curran, 1928. This group may be characterized as follows: forcipes interiores absent; forcipes superiores strongly chitinized an dilated at anex. Within this group, the forcipes of. A. seabrai sp. n. do not present an aberrant form. The "dissimilis group" will be studied in forthcoming papers. The limits of the genus Archyta Jaen. are not as yet sharply difined, the evaluation of the significance of each character used in the definition remaining as most difficult problem. The distinction between Archytas and other related genera is very difficult, chiefly because it is based on variable characters. In this paper we place the genera Parafabricia Towsend, 1931, Itachytas Blanchard, 1940, Archynemochaeta Blanchard, 1941, Proarchytoides Blanchard, 1941 and Archytodejeania Blanchard, 1941 in the synonymy of Archytas Jaen. The detailed examination of the characters used in their definition, proved them to be fundamentally proposed on basis of chaetotasy, these characters alone being precarious, because of the considerabel intraspecifical variation. The type of the new species are in the Oswaldo Cruz Institute collection. Rio de Janeiro, Brazil, and paratypes in the collections of the followings institutions: Departamento de Zoologia da Secretaria de Agricultura do Estado de São Paulo; Instituto de Ecologia e Experimemtação Agrícolas; Departamento de Defesa Sanitária Vegetal; Campos Seabra collection; and Barbiellini collection.

Freedom Trial First-Year Extension: Results from 4 Years of Denosumab Exposure in Women with Postmenopausal Osteoporosis

Aims: To investigate the long-term efficacy and safety of denosumab (DMAb) for the treatment of postmenopausal women with osteoporosis in an open-label extension to the 3-year FREEDOM study.1Methods: All women who completed the FREEDOM study were eligible to enter a long-term open-label extension (up to 10 years). After providing informed consent, participants received 6-monthly subcutaneous injections of DMAb (60 mg). Here we report data from the first year of followup. For women randomized to DMAb in the FREEDOM study ('long-term group'), this represents up to 48 months of DMAb exposure (eight 6-monthly injections). For those randomized to placebo ('de novo group') the data are from up to 12 months of exposure (two injections). All participants continued to take calcium (1 g) and vitamin D (≥400 IU) supplements daily. Changes in bone mineral density (BMD) and bone turnover markers (BTM) are reported for subjects enrolled in the extension. No formal statistical testing was planned for this interim report. P-values are descriptive.Results: Overall, 4,550 eligible women (70.2%) who completed the FREEDOM study entered the open-label extension study (long-term, n=2,343; de novo, n=2,207). During the first year of the extension, lumbar spine (LS) BMD in the long-term group further increased by 2.0% (12.1% increase vs. FREEDOM baseline at 48 months), and total hip (TH) BMD further increased by 0.8% (6.5% increase at 48 months) (p<0.0001 for both BMD gains during year 4; Fig. 1). During the first year of the extension, LS and TH BMD increased by 5.4% and 3.0%, respectively in the de novo group (both p<0.0001). After DMAb initiation, serum C-telopeptide (CTX) in the de novo group decreased rapidly and similarly to the long-term group (Fig. 2). Reductions in BTMs continue to attenuate at the end of the dosing interval as previously reported. Adverse event (AE) rates were similar (70.4% of women in the longterm group and 67.9% in the de novo group). Serious Aes were also similar (9.8% and 11.2% of women, respectively). During year 4, osteoporotic nonvertebral fractures were reported in 31 women in the long-term group and 51 in the denovo group.Fig. 1. Percentage change in BMD with denosumab for4 years (long-term) or 1 year (de novo)Fig. 2. Percentage change in sCTX over timeConclusions: These interim results suggest that continuation of DMAb treatment through 48 months is associated with further significant increases in spine and hip BMD with sustained reduction of bone turnover. The de-novo treatment group results confirm the first year active treatment findings previously reported1.Acknowledgements: Amgen Inc. sponsored this study.
