Ecological distribution of the prawn Nematopalaemon schmitii (Crustacea: Decapoda: Caridea) in three bays on the southeastern coat of Brazil

The relationships between the spatial and temporal variations in the abundance of the shrimp Nematopalaemon schmitti and water temperature, salinity, and texture and organic-matter content of the sediment, were analysed in Ubatumirim, Ubatuba and Mar Virado bays on the northern coast of São Paulo, Brazil. Sampling was carried out monthly, from January 1998 through December 1999, from a shrimp boat equipped with double-rig nets, along six transects in each bay. In total, 2 116 specimens of N. schmitti were caught. Their distribution differed among bays, transects and seasons (ANOVA, p < 0.05). Highest total abundance was found in areas of high organicmatter content, in substrate composed mainly of very fine sand and silt and clay, and during winter and autumn. Although multiple regression analysis showed no significant relationship (p > 0.05), observations suggest that water tempera ture, sediment texture, organic-matter content, and the presence of biodetritus and plant fragments, provided favourable environmental conditions for the establishment of N. schmitti in the region.

Growth and mortality parameters of Paranchurus brasiliensis (Scianidae) captured as bycatch in southeastern of Brazil

The present work provides preliminary informations on the growth and mortality of Paralonchurus brasiliensis captured as a bycatch in the inner shelf of São Paulo Southeastern Brazil. The samplings were carried out using a shrimp fishery trawl. After trawling, the specimens were separated from the other organisms and the fish size and numbers of individuals captured were recorded. A total of 5,943 specimens ranging from 3.6 to 19.9 cm in standard length were sampled.

Growth and flowering of five mango cultivar under subtropics conditions of Brazil

The evaluation of the new cultivars adaptation and yield potential of Mangifera indica L. provides tools to assist and improve the mango production in different climates conditions. This study aimed to evaluate the phenological and reproductive development of five mango cultivars (Bourbon, Haden, Palmer, Parwin and Tommy Atkins), on climate conditions in dry land and four production cycles (from 08/2007 to 01/2011), at São Manuel, São Paulo state, Brazil. The variables were total plant height, trunk height, stem diameter and the first insertion diameter, fruits physical characteristics, yield and harvest period, flowering seasonality and morphological characterization of the inflorescences. It was found that the four-year-old plants of Haden cv. reach 4.0 m high and 0.20 m of trunk diameter. Bourbon cultivar had the highest flowering period, from April to October. Tommy Atkins cv. had productivities of 14779.07 kg∙ha−1 in the fourth cycle and the productivity of Bourbon, Haden and Palmer cultivars was alternated.

Variation of soil and water volumes in riparian jungle soils of Brazil

The objective of this work is to study the relation between humidity, density, porosity and shrinkage of the floodplain soil and riparian vegetation and their ability to store water. For this purpose, two locations for every type of soils were evaluated. Both were placed at the Agronomy University (Faculdade de Ciências Agronômicas) in São Manuel, State of São Paulo, Brazil. The floodplain soil was vegetated with Southern Cattail (Typha domingensis). In both places, soil samples were collected from several depths: 0, 30, 60 and 100 cm. Results show that lower soil density values (0.15 g/cm3) with organic texture and high porosities values (up to 86.2%) were found in samples with the highest organic material content in the floodplain soil. For this field experiment, flood plains soils (characterised as basin gley soils) presented high volumetric instability with a retratibility of 67.49% and higher water storage capacities compared to riparian stands soils (characterised as fluvic neosoils).

Fatores ambientais e estimativa de herdabilidade para o intervalo desmame-cio de fêmeas suínas

Este trabalho foi realizado com os objetivos de avaliar a influência de fatores ambientais e estimar a herdabilidade para a característica intervalo desmame-cio (IDC) de fêmeas suínas. Para isso, utilizaram-se 1.032 observações de 347 porcas Dalland (C-40), pertencentes a dois rebanhos. No modelo, incluíram-se como aleatórios os efeitos do pai e da mãe da porca e, como fixos, os efeitos do ano de parto, do rebanho e da estação de parição, bem como as co-variáveis idade da porca ao parto, tamanho da leitegada ao nascer e período de lactação. As estimativas dos componentes de variância e do parâmetro genético foram obtidas utilizando-se o aplicativo MTDFREML, que emprega a metodologia da máxima verossimilhança restrita livre de derivadas. A média foi de 5,3 dias, com um coeficiente de variação de 71,44%. O período de lactação teve influência linear sobre o IDC. do mesmo modo, a regressão quadrática do IDC em relação à idade da porca ao parto foi significativa. O pai e a mãe foram importantes fontes de variação no intervalo desmame-cio, que, provavelmente pelo fato de acontecer tardiamente na vida do animal, não foi influenciado pelo rebanho, pelo ano e pela estação. A estimativa de herdabilidade para o primeiro intervalo desmame-cio foi de 0,11, o que indica que esta característica não apresentaria ganho genético satisfatório como resposta à seleção individual.

Efeitos genéticos e não-genéticos sobre o intervalo de parto em fêmeas suínas no Sudeste do Brasil

The effect of environmental and genetic effects on the farrowing interval in Dalland (C-40) sows in the Southeast of Brazil was studied. Data consisting of 1,013 farrowing intervals recorded in two herds were analyzed, using a model that included the sire and the dam as random effects and the year of farrowing, the herd and the farrowing season as fixed effects, plus the covariables sow's age at farrowing, litter size at birth, lactation length and weaning-estrus interval. For the farrowing interval first only, variance components were estimated by REML, with an animal model that included, as fixed effect, a contemporary group and, as random effects, the additive genetic variance and the error. The mean farrowing interval was 140.9+5.7 days, with a 4.0% coefficient of variation. Variance analysis showed no effect of either year, season of farrowing or herd on the farrowing interval. The sire effect was not important for the farrowing interval, but the dam represented an important source of variation. The total number of piglets born and the sow's age at farrowing had no influence on the farrowing interval. The length of lactation exerted an influence on the farrowing interval, accounting for 19.4% of the total variation of this trait. Likewise, the linear regression of the weaning-estrus interval in relation to the farrowing interval was highly significant, accounting for 51.7% of the total variation. The heritability estimate was 0.00, suggesting that no genetic gain can be obtained by selection for a shorter farrowing interval.

Tinea capitis: epidemiologia e ecologia dos casos observados entre 1983 e 2003 na Faculdade de Medicina de Botucatu, Estado de São Paulo, Brasil

FUNDAMENTOS: Tinea capitis é importante infecção fúngica de interesse dermatológico e pediátrico. No Brasil sua prevalência é desconhecida, e os agentes causais principais são o Trichophyton tonsurans nas regiões Norte-Nordeste e o Microsporum canis no Sul-Sudeste do país. Conhecimento sobre gênero e espécies mais prevalentes tem importância sanitária e terapêutica. OBJETIVOS: Identificar espécies de dermatófitos, causa de Tinea capitis, em serviço universitário que atende clientela do Sistema Único de Saúde, de procedência urbana e rural, no interior do Estado de São Paulo. MÉTODOS: Amostras de casos clínicos suspeitos de Tinea capitis, procedentes da área de abrangência da Faculdade de Medicina de Botucatu-Unesp, foram investigadas por exame direto e cultivo visando ao diagnóstico e isolamento do agente causal. RESULTADOS: de 1.055 suspeitas, 594 foram confirmadas por exame direto, em 364 (61,1%) isolou-se o agente: M. canis em 88,2%, seguindo-se T. tonsurans (4,7%), T. rubrum (3,3%), M. gypseum (1,9%), T. mentagrophytes (1,6%). O sexo masculino correspondeu a 55,7% dos casos, e a faixa etária entre 0-5 anos predominou com 62,6% (p < 0,05). CONCLUSÕES: A prevalência detectada do M. canis superou o esperado para a Região Sudeste do Brasil. A freqüência de 88,2% pode estar influenciada por pacientes procedentes da zona rural. Esse dado deve ser considerado quando de decisão terapêutica.

Microbial culture collections as pillars for promoting fungal diversity, conservation and exploitation

Fungi are a diverse group of organisms with an overall global number of 1.5 M up to 3.3 M species on Earth. Besides their ecological roles as decomposers, fungi are important in several aspects of applied research. Here, we review how culture collections may promote the knowledge on diversity, conservation and biotechnological exploitation of fungi. The impact of fungi diversity on biotechnological studies is discussed. We point out the major roles of microbial repositories, including fungal preservation, prospecting, identification, authentication and supply. A survey on the World Data Center for Microorganisms (WDCM) powered by the World Federation for Culture Collections and on the Genetic Heritage Management Council (CGEN) database revealed that 46 Brazilian culture collections registered in these databases are dedicate to preserving fungi. Most of these culture collections are located in the Southeast of Brazil. This scenario also demonstrates that Brazil has many collections focused on fungal strains, but the lack of up-to-date information in WDCM as well as of a solid national platform for culture collections registration do not allow accurate assessment of fungal preservation. © 2013 Elsevier Inc.
