Crescimento e produção de genótipos de bananeiras em clima subtropical

O presente trabalho teve como objetivo avaliar as características de crescimento e o potencial produtivo de genótipos de bananeira em Botucatu/SP. Foram avaliadas características de crescimento, tais como altura de planta, circunferência do pseudocaule, número de folhas e número de dias entre o florescimento e a colheita. Estas medidas foram realizadas na emissão da inflorescência. Foram mensuradas também as características de produção, como peso do cacho, número de frutos, peso médio dos frutos, produtividade, número de pencas; peso, número, comprimento e diâmetro dos frutos da 2a penca. O delineamento adotado foi o inteiramente casualisado, com 11 tratamentos (genótipos), cinco repetições e duas plantas úteis por parcela experimental. Os genótipos que apresentaram melhor desempenho agronômico, dentro de cada grupo genômico, foram 'Grand Naine'(AAA), 'Thap Maeo' (AAB) e 'Fhia 01' (AAAB).

Produção e qualidade dos frutos de pessegueiro e nectarineira em clima subtropical do estado de São Paulo

Tendo em vista que o conhecimento do comportamento de uma cultura, em determinada região, determina o sucesso da produção, a qualidade do produto final e a garantia de aceitação pelo mercado consumidor, o presente trabalho teve como objetivo avaliar a produção e as características físicas e físico-químicas de frutos de cultivares de pessegueiro e nectarineira, cultivados ou não tradicionalmente em São Paulo, mas que possam vir a apresentar uma opção de diversificação aos fruticultores do município de Botucatu-SP, e regiões climáticas semelhantes. O experimento foi realizado durante três ciclos agrícolas: 2006/2007, 2007/2008 e 2008/2009, na Faculdade de Ciências Agronômicas, UNESP, Botucatu-SP. O clima da região é do tipo mesotérmico, Cwa, ou seja, subtropical úmido com chuvas no verão e seca no inverno. As cultivares de pessegueiro avaliadas foram: Turmalina, Cascata 968, Cascata 848, Cascata 587, Conserva 693, Precocinho, Diamante Mejorado, Oro Azteca, CP-9553CYN e Tropic Beauty. A cultivar de nectarineira avaliada foi 'Sun Blaze'. Foram avaliadas características de produção e qualidade dos frutos. Os resultados obtidos permitiram concluir que a cultivar Turmalina foi a mais produtiva. As cultivares Cascata 968 e Diamante Mejorado apresentaram o maior teor de sólidos solúveis, e as cultivares Cascata 587 e CP 9553 CYN, a maior relação sólidos solúveis/acidez titulável.

Affective disorders, hospital admissions, and seasonal variation of mania in a subtropical area, southern hemisphere

Hospital admissions (n = 15,450) to a state psychiatric hospital in Botucatu, São Paulo State, Brazil, over a 10-year period (1982-1991) were reviewed. 157 (1%) patients received a probable diagnosis of affective disorder according to DSM-III-R criteria. Among them, 46% had been diagnosed by the staff psychiatrists, and their diagnoses were sustained by the researchers, whereas 54% were diagnosed only by one of the researchers (F.K.C.). These last patients had previously received a diagnosis of paranoid schizophrenia or unspecified psychosis (ICD-9). Most of the patients with affective disorders were bipolar: 72 and 8%, respectively, presented manic and depressive episodes. Thus, only 20% received a diagnosis of major depression. A seasonal pattern in hospital admission was observed only for mania in women, their episodes occurring more often (p < 0.02) in spring and summer. No significant seasonal pattern in hospital admission for depression was found.

Feeding behaviour and ecosystem role of the red mangrove crab Goniopsis cruentata (Latreille, 1803) (Decapoda, Grapsoidea) in a subtropical estuary on the brazilian coast

This study provides information concerning the feeding behaviour of Goniopsis cruentata (Latreille, 1803), through analysis of stomach contents according to demographic categories. Collections were carried out monthly from May 2005 through April 2006 in a subtropical estuary on the southeastern Brazilian coast (23 degrees 29'24 '' S 45 degrees 10'12 '' W). The crabs were collected by hand, with a 2-hour sampling effort by three people. In the laboratory, the crabs were sexed and measured for greatest carapace width, and grouped into demographic categories: adult males, juvenile males, adult females, juvenile females, and ovigerous females. For the fullness analysis, the stomachs were grouped into two categories: (1) E = Empty, with no food; and (2) F = Full, whether partially filled or totally. The frequency-of-occurrence method was used to characterize feeding behaviour, and the demographic categories recognired were compared. We obtained stomachs from 171 adult males, 69 juvenile males, 136 adult females, 72 juvenile females, and 41 ovigerous females, of which 85.6% were full. of the eight food items recorded, sediment was the most frequent, and unidentified material was the least. Goniopsis cruentata can be characterized as a generalist feeder, exploiting most of the food items available in the mangrove swamps. In spite of this generalist behaviour, the dominant presence of sediment suggests that G. cruentata is primarily a detritivore that exploits particulate organic matter from microbial biodegradation, one of the most important mangrove functions. The trophic role of this crab in the ecosystem showed no significant differences among the demographic categories, and seems to be wider than those observed for sesarmid and ocypodid mangrove crabs. These ecosystem engineers may occupy different positions in the trophic chains of estuarine environments.

Population and reproductive biology of the crab Uca burgersi (Crustacea : Ocypodidae) in three subtropical mangrove forests

Population and reproductive biology were studied in three populations of the crab Uca burgersi Holthuis, 1967, in the Indaia, Cavalo and Ubatumirim mangrove forests (Ubatuba, São Paulo State, Brazil). Crabs were collected during low tide (August 2001 through July 2002), by digging the sediment, with a standard capture effort (two persons for 30 min.). Carapace width was measured, and gonad developmental stage was recorded from all specimens. U. burgersi was most abundant in the Cavalo mangrove, where the largest mate was found. Juvenile crabs were found year-round at all three sites. However, the ratio of ovigerous females was very low, even null in the Cavalo mangrove. The gonad development rate indicated that U. burgersi was reproducing continuously, but more intensively during spring and summer, with recruitment occurring in winter. The synchrony between the populational and reproductive biology in the three areas showed that local features were not the limiting factors. It is suggested that this species is a habitat generalist.
