Effects of essential fatty acids and N and P-limited algae on the growth rate of tropical cladocerans

Abstract: SUMMARY 1. In this study, the effects of nutrient (N and P) deficiency and the importance of essential polyunsaturated fatty acids (PUFA) [eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] to tropical cladocerans, growth and reproduction were determined in a growth bioassay. 2. The animals were fed N/P-sufficient, N-deficient and P-deficient algae, and also N and P-deficient algae supplemented with fish oil emulsions rich in EPA and DHA. 3. Cladocerans showed different responses to nutrient-deficient algae and also to supplements of fish oil emulsions. Moina micrura was most sensitive to P-deficient alga and, surprisingly, grew better and produced more eggs in N-deficient alga than in N/P sufficient alga. Ceriodaphnia cornuta was less sensitive, growing well in both N and P-deficient algae. This species, however, had a lower clutch size in N-deficient alga. On the other hand, Daphnia gessneri was the most sensitive to mineral limitation, showing decreased growth and clutch size in both nutrient-deficient algae. 4. The PUFA supplements to nutrient-deficient algae increased growth rates only for M. micrura and C. cornuta, suggesting that these fatty acids are important food requirements for these species.

New Data on the Clevosaurus (Sphenodontia: Clevosauridae) from the Upper Triassic of Southern Brazil

Abstract: The sphenodontian fossil record in South America is well known from Mesozoic and Paleogene deposits of Argentinean Patagonia, mainly represented by opisthodontians, or taxa closely related to the modern Sphenodon In contrast, the Brazilian fossil record is restricted to the Caturrita Formation, Late Triassic of Rio Grande do Sul, represented by several specimens of Clevosauridae, including Clevosaurus brasiliensis Bonaparte and Sues, 2006 Traditionally, Clevosauridae includes several Late Triassic to Early Jurassic taxa, such as Polysphenodon, Brachyrhinodon, and Clevosaurus, the latter well-represented by several species The detailed description of the specimen MCN-PV 2852 allowed the first systematic revision of most Clevosaurus species Within Clevosauridae, Polysphenodon is the most basal taxon, and an IterPCR analysis revealed Brachrhynodon as a possible Clevosaurus; C petilus, C wangi, and C mcgilli as possibly distinct taxonomic entities; and the South African Clevosaurus sp is not closely related to C brasiliensis These data indicate the need of a deep phylogenetic review of Clevosauridae, in order to discover synapomorphic characters among the diversity of these Triassic/Jurassic sphenodontians

Anti-bullying interventions in schools: a systematic literature review

Abstract: Resumo Este artigo apresenta uma revisao sistematica da literatura referente a intervencoes rigorosamente planejadas e avaliadas na reducao do bullyin escolar. O levantamento dos artigos foi realizado em quatro bases de dados (Lilacs, Psycinfo, Scielo e Web of Science) orientado pela questao norteadora: Em relacao ao bullyin, quais sao as intervencoes empreendidas para a sua reducao nas escolas? Foram incluidos somente estudos do tipo caso-controle, com foco especifico no bullyin escolar e sem recorte temporal. A qualidade metodologica das investigacoes foi avaliada por meio do check-list SIGN. No total, 18 artigos compuseram o corpus de analise da revisao e todos foram avaliados como de alta qualidade metodologica. As intervencoes realizadas nos estudos revisados foram subdividas em quatro categorias: multidimensionais ou em toda a escola, treinamento de habilidades sociais, curriculares e informatizadas. A revisao sintetiza conhecimentos que podem ser utilizados para pensar praticas e programas de intervencao no Brasil, nas areas da educacao e da saude, com carater multiprofissional.
