The diatom flora of the shallow lakes in the Pantanal of Nhecolândia is poorly known. Thus, our aim was to know the diatom biodiversity in three types of shallow lakes called baías, salitradas and salinas, characterized by differences in pH, electrical conductivity, contact with the coalescent system and the presence of macrophytes. The samples were collected in dry and rainy seasons, from 2004 to 2007. For taxonomic identification, the material was cleaned with H2O2 and analyzed using light microscopy. A total of 23 diatom species were identified and each lake presented a unique species richness and composition. The greatest species richness was found in the Baía da Sede Nhumirim (21 species), followed by the Salitrada Campo Dora (8 species) and finally the lowest species richness was observed in the Salina do Meio (3 species). Only Anomoeoneis sphaerophora Pfitzer var. sphaerophora and Craticula cf. buderi (Hustedt) Lange-Bertalot occurred in the three studied systems. Except for Eunotia binularis (Ehrenberg) Souza and Aulacoseira ambigua (Grunow) Simonsen, all the others are new records to the Brazilian Pantanal.

The aim of this study was to estimate genetic parameters for growth traits in Somalis Brasileira hair sheep breed. The data used in this study were from the flock of Embrapa Caprinos and Ovinos, located in the city of Sobral - CE, Brazil. Data contained records of 1,120 animals in the pedigree file. The analyzed traits were birth weight (PN), weaning weight (PD), weight gain from birth to weaning (GND) and adult weight (PA). Estimates of (co)variances and genetic parameters were obtained by Derivative Free Restricted Maximum Likelihood Method (DFREML) using the MTDFREML software. The heritabilities were low to moderate in univariate analysis. The maternal heritabilities were higher than direct heritabilities. The heritabilities in multivariate analysis exceeded those in univariate analysis. The values of genetic correlations varied widely.

This study reports on the occurrence of Molossus coibensis J. A. Allen, 1904, in the Brazilian Amazon and the second record of this species from Brazil. It also presents a comparative analysis with other two small-bodied Molossus species that occur in Brazil: M. molossus (Pallas, 1766) and M. aztecus Saussure, 1860. The report is based on 8 females captured in urban areas of the city of Bragança, in the northern Brazilian state of Pará. Morphometric data and the qualitative comparison of morphological features permitted the identification of the specimens as M. coibensis, hitherto known only in Tapirapoan, in the southwestern state of Mato Grosso, west-central Brazil. © SAREM, 2013.

El trabajo proporciona un análisis detenido de las tendencias actuales y perspectivas futuras de la familia en Brasil, con énfasis en: a) los procesos asociados a los cambios y permanencias en las unidades domésticas y familias; b) la estructura y formas de crecimiento de las unidades domésticas: familias y no-familias; c) los tipos de familias: la diversificación del modelo conyugal, el surgimiento del modelo monoparental y los determinantes próximos de estas estructuras; d) la dinámica interna de la familia: la formación y la expansión; e) las familias de mujeres; f) las familias de los hijos; g) las familias de los ancianos; h) las perspectivas de la familia.
