TL;DR: In this article, the authors identify the risk factors to which children with delayed development referred to the Center of Applied Psychology of FFCLRP-USP over the last five years had been exposed.
Abstract: The objective of the present study was to identify the risk factors to which children with delayed development referred to the Center of Applied Psychology of FFCLRP-USP over the last five years had been exposed. The group consisted of 12 boys and 10 girls ranging in age from 1 month to 8 years. The data were extracted from the interviews held with the mothers as the time of child enrollment in the service. The problems reported by de mothers on the occasion of the complaint and the adverse events and circumstances that ocurred in the child’s life were classified according to the Category System elaborated by the authors of the present study. The results showed that, in addition to retardation, the most frequent problems reported on the occasion of the complaint were speech, motor coordination, learning and agitation/restlessness problems. Analysis of the adverse circumstances in the life history of this group of children demonstrated that all of them had been exposed to one or more biological risk conditions, the most frequent being congenital problems, mother’s physical health problems during pregnancy, child’s physical health problems, convulsive seizures, complications of delivery, and hospitalization. Furthermore, 36% of the children had been exposed to environmental risk factors, especially those linked to inadequate attitudes and practices of care and education. On the basis of the results obtained, we discuss the implications of the presence of biological risks as an important condition for access to specialized services on the part of the children and their families.

TL;DR: Evidence is provided that the social paper wasp Polistes satan is a successful predator on the larvae of two economically important and resilient crop pests, the sugarcane borer Diatraea saccharalis and the fall armyworm Spodoptera frugiperda.
Abstract: Biocontrol agents can help reduce pest populations as part of an integrated pest management scheme, with minimal environmental consequences. However, biocontrol agents are often non-native species ...

TL;DR: In the transects IV and V, the highest values of diversity and smaller abundance of shrimp X. kroyeri were found and the similarity in relation to other points has low similarity due to its characteristics, such as location in the bay and type of substrate.
Abstract: The aims of this study were to identify spatially and temporally the composition and diversity of decapod crustaceans caught at fisheries of shrimp Xyphopenaeus kroyeri in Ubatuba bay. Samples were obtained monthly with a shrimping boat from September 1995 to August 1996 at 8 permanent transects. In total were collected 233094 individuals belonging to 85 species. The greatest riches were obtained for Brachyura (49 species) and Anomura (16 species). In the transects IV and V, the highest values of diversity and smaller abundance of shrimp X. kroyeri were found. Regarding the similarity, transects IV and V has low similarity in relation to other points due to its characteristics, such as location in the bay and type of substrate. Studies on the diversity of bycatch of commercially important shrimps are essential for management plans and conservation of renewable natural resources.

TL;DR: A model where evolution of sexual dimorphism in 2D:4D first originates from the advent, in a given digit, of increased tissue sensitivity to steroids is proposed and might explain several cases of steroid-mediated integration among sexually dimorphic traits.
Abstract: Developmental associations often explain phenotypic integration. The intersected hormonal regulation of ontogenetic processes fosters predictions of steroid-mediated phenotypic integration among sexually dimorphic traits, a statement defied by associations between classical dimorphism predictors (e.g. body size) and traits that apparently lack sex-specific functions (e.g. ratios between the lengths of Digits II and IV - 2D:4D). Developmental bases of female-biased 2D:4D have been identified, but these remain unclear for taxa presenting male-biased 2D:4D (e.g. anura). Here we propose two alternative hypotheses to investigate evolution of male-biased 2D:4D associated with sexually dimorphic body size using Leptodactylus frogs: I)‘hypothesis of sex-specific digit responses’ - Digit IV would be reactive to testosterone but exhibit responses in the opposite direction of those observed in female-biased 2D:4D lineages, so that Digit IV turns shorter in males; II) ‘hypothesis of identity of the dimorphic digit’- Digit II would be the dimorphic digit. We compiled the following databases using Leptodactylus frogs: 1) adults of two species from natural populations and 2) testosterone-treated L. fuscus at post-metamorphic stage. Studied traits seem monomorphic in L. fuscus; L. podicipinus exhibits male-biased 2D:4D. When present, 2D:4D dimorphism was male-biased and associated with dimorphic body size; sex differences resided on Digit II instead of IV, corroborating our ‘hypothesis of identity of the dimorphic digit’. Developmental steroid roles were validated: testosterone-treated L. fuscus frogs were smaller and exhibited masculinized 2D:4D, and Digit II was the digit that responded to testosterone. We propose a model where evolution of sexual dimorphism in 2D:4D first originates from the advent, in a given digit, of increased tissue sensitivity to steroids. Phenotypic integration with other sexually dimorphic traits would then occur through multi-trait hormonal effects during development. Such process of phenotypic integration seems fitness-independent in its origin and might explain several cases of steroid-mediated integration among sexually dimorphic traits.
