The objectives of the present study is to describe the size for exploitation and gonadal maturation of L. pectinata in Peças Island in Paraná coast. Twenty two individuals were sampled every month, from an intertidal flat of the Peças River, Municipality of Guaraqueçaba, during two periods -summer/autumn and winter of the 2009. Environmental parameter data was obtained at the same time of the biological sampling: temperature, salinity and seawater transparency at the Peças River mouth. The animals' height, length, width, gross weight, wet weight of meat and dry weight of meat were measured at the lab. The gonad development stages (GDS), condition index (CI) and yield index (Y) were calculated. Sex identification was conducted by direct observation of the gonads and gametes under an optic microscope. Individuals were classified as males (M), females (F) or undetermined (U). The medium height observed was of 49.62 ± 6.84 mm. Period of more expressive gonad repletion were observed in summer when water temperature was higher. Results of GDS in both periods showed a predominance of partially filled gonad stages. This may be related with the fact that L. pectinata has intense gametogenesis activity, that is, the organisms do not have a resting interval, but go back to gonad restructuring rapidly after releasing the gametes. The continuity of the reproductive cycle of the specimens found in both studied periods could demonstrate a possible continuous reproduction of the species and a size for exploitation above 40.00 mm of height.Keywords: reproduction, clams, Peças Island, condition index. Período reprodutivo de Lucina pectinata (BIVLAVE; LUCINIDAE) no Complexo Estuarino de Paranaguá, PR -BrasilResumo O presente estudo tem como objetivo descrever o tamanho de exploração e a maturação gonadal de L. pectinata na Ilha das Peças no litoral do Paraná. Vinte e dois indivíduos foram amostrados mensalmente na região entre-marés no Rio das Peças, Município de Guaraqueçaba, durante 2 períodos -verão/outono e inverno de 2009. Paralelamente às amostragens, foram obtidos dados dos parâmetros ambientais: temperatura, salinidade e transparência da água do mar na foz do Rio das Peças. A altura, comprimento, largura, peso bruto, peso úmido da carne e peso seco da carne dos animais foram medidos no laboratório. Foram calculados os estágios de desenvolvimento gonadal (EDG), índices de condição (IC) e de rendimento (R). A Identificação do sexo foi realizada por observação direta das gônadas e gametas sob microscópio óptico. Os indivíduos foram classificados como: machos (M), fêmeas (F) ou indeterminados (I). A altura média observada foi de 49,62 ± 6,84 mm. O período de maior repleção gonadal foi observado no verão, quando a temperatura da água foi mais elevada. Resultados dos EDG em ambos os períodos mostrou um predomínio de gônadas parcialmente cheias. Isso pode estar relacionado com o fato de que L. pectinata tem atividade gametogênese intensa, ou seja, os organismos não têm um intervalo de repouso, mas voltam a reestruturação ...

In order to perform a concise characterization and evaluation of the butterflies taxocenosis structure of the Rural Health and Technology Center (CSTR) of the Federal University of Campina Grande (UFCG), a semiurban area of the Caatinga biome, Semiarid region, in the Septentrional Sertaneja Depression Ecoregion, a species inventory with entomological net was conducted. There were recorded 81 species of butterflies, distributed in a general abundance of 2531 individuals; among them, 808 specimens were captured and collected, and none of the individuals marked with nontoxic pen and released were recaptured. The list of species was complemented by adding nine more butterflies species, mostly Hesperiidae, from collection before and after the sampling period,constituting a total of 90 species. Many of the butterflies species found in the CSTR are new records for Paraíba state and only four species are considered for the Northeast geographic region, based on other checklists for areas of Atlantic Forest, Caatinga, Cerrado and Amazon biomes in this region: Junonia genoveva infuscata Felder & Felder, 1867, Staphylus melangon epicaste Mabille, 1903, Clito sompa Evans, 1953 and Lerema ancillaris (Butler, 1877).

RESUMO REPRODUCTIVE ASPECTS OF MUSSELS (BIVALVIA, MOLLUSCA) IN THE PARANAGUÁ ESTUARINE COMPLEX, PARANÁ, BRAZIL ABSTRACTThe objective of this work was to study the reproductive period of the shellfishes (Mytella guyanensis and Mytella charruana) in the Paranaguá Estuarine Complex (CEP). Thirty adult individuals of each species were collected monthly during August/1999 to July/2000. The organisms were measured, weighed and opened mechanically by sectioning the adductor muscles. Sex identification and reproductive stage were evaluated and the condition (IC) and meat yield (MY) indexes were calculated. IC results indicated annual average of 13.25% (±6.95) for M. guyanensis and of 17.65% (±12.11) for M. charruana. For R, average of 43.68% (±10.15) was observed for M. guyanensis and of 51.22% (±8.64) for M. charruana. Results of the reproductive studies allow to conclude that the gametes elimination occurs partially for the two species, with two higher periods of spawning in the year.
