Abstract: diversity of calliphoridae and sarcophagidae (diptera, oestroidea) in continuous forest and gaps at different stages of regeneration in the urucu oilfield in western brazilian amazonia. the diversity of calliphoridae and sarcophagidae in continuous forest and gaps at different stages of regeneration was studied in the urucu river basin, in coari, state of amazonas, brazil. the flies were collected at 16 sampling points, 12 in gaps at different stages of regeneration (early _ c1, mid- c2 and late successional _ c3) and four in continuous forest _ mt. the diversity of blowflies was similar in the two less regenerated habitats (c1 and c2), and lower than that in the late successional (c3) and continuous forests (mt). by contrast, the diversity of flesh flies was much higher in all three types of gaps (c1, c2 and c3) in comparison with continuous forest (mt). ordination (nmds) and similarity (anosim) analyses revealed that the blowflies communities were grouped by habitat type, which affected species composition more than diversity. analysis of the flesh flies revealed two main groupings, gaps (c1, c2 and c3) and continuous forest (mt), with no evidence of any influence of successional stage on the diversity of the community.

Abstract: blowflies have sanitary and forensic importance, and different levels of association with human settlements (synanthropy). therefore, specific diversity changes in each site could be used as an indicator of the anthropic impact. in this study, the community of calliphoridae in hudson (argentina) was sampled in three sites with different degrees of synanthropy (natural, rural and urban). flies were attracted with bait and collected with an insect net. twelve samples were collected in each site and both simpson and shannon diversity indexes were calculated. the natural area was the most diverse. the other two areas showed no significant differences between them. the diversity was higher in the middle of spring and in late summer, and lower at the end of spring and in the beginning of summer. alterations due to human settlements affect diversity by decreasing the abundance of some species.

Abstract: a structured snake inventory was carried out at the base operacional geólogo pedro de moura (bogpm), located at the urucu petrol basin, municipality of coari, amazonas, during 2003, 2004 and 2007. throughout four sampling expeditions (51 collection days), seven species of snakes, belonging to seven families and 33 genera, were recorded. four complementary sampling methods were used: pitfall traps with drift fence, occasional encounters, time-limited search on foot and time-limited search by car. of the 47 collected species liophis reginae (n= 14), philodryas viridissima (n= 9), philodryas boulengeri (n= 7) and oxybelis fulgidus (n= 7) were the most abundant in the region. the highest number of species and specimens was obtained by the time-limited search by car (n=52.8%). previous studies indicate that localities south of the amazonas river (such as the eastern region of pará and tucuruí, state of para, and samuel hydroelectric plants, state of rond?nia) present a greater richness when compared to those north of the amazonas river (such as the mucipality of manaus, inpa-wwf reserve and balbina hydroelectric plant, state of amazonas).thus, it is possible to infer that the snake inventory in urucu region is not yet complete, requiring more sampling efforts so that new records can be obtained for the area.

Ambiente e água : An Interdisciplinary Journal of Applied Science , 2007,
Abstract: Este trabalho realizado, na bacia hidrográfica do ribeir o Itaim, município de Taubaté, SP, visou estimar o escoamento superficial pelo método Curva-Número (CN) em área com cobertura vegetal de Brachiaria Decumbens, que é predominante na bacia. Valores do CN foram definidos em fun o do uso e cobertura do solo. O escoamento superficial (Q) foi estimado por três métodos: 1o) utilizaram-se-se valores de infiltra o acumulada (IAc) obtidos no campo, considerados como Infiltra o Potencial (S), os quais variaram de 15,37 mm a 51,88 mm com um valor médio de 23,46 mm. Com esses valores de infiltra o e utilizando-se valores de precipita es máximas para Taubaté, SP, com tempo de dura o de 3 horas: P = 54,4; 70,3; 80,8; 86,7; 90,9; 94,1 e 103,9 mm, respectivamente, para os tempos de retorno de Tr = 2, 5, 10, 15, 25, 50 e 100 anos, os seguintes valores de (Q) foram obtidos: 34,83; 49,33; 59,14; 64,71; 68,69; 71,73 e 81,10 mm, respectivamente; 2o) considerou-se a predominancia de Pasto Sujo na bacia e utilizando-se o valor adimensional CN = 75, obteve-se S = 84,7 mm e chegou-se aos valores de (Q) que variaram de 11 a 44 mm; 3o) considerou-se o valor ponderado para todas as classes de uso da bacia, CNponderado= 66,57, e obteve-se um valor mais elevado para infiltra o potencial, S =127 mm. Conseqüentemente, os resultados dos valores de (Q) foram mais baixos e corresponderam a 5,33; 11,64; 16,72; 19,83; 22,16; 23,98 e 29,83 mm, respectivamente. Dessa forma, concluiu-se que o método CN (tanto para a classe predominante quanto para o ponderado) subestimou o escoamento superficial na área estudada. Entretanto, é possível sua utiliza o desde que se promovam os ajustes para as situa es locais com base em medidas prévias de infiltra o em campo.
