ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophysiognomies (Restinga Forest, REF; Lowland Ombrophilous Dense Forest, LLF; and Montane Ombrophilous Dense Forest, MTF). Spore abundance was lowest in LLF and highest in REF, with no statistical differences relative to MTF. Spore diversity indices and root colonization rates were not statistically different among the phytophysiognomies. However, principal components analysis revealed that AMF community structure differed according to forest phytophysiognomy. Hierarchical partitioning analysis indicated that most of the AMF community variables were better explained by phytophysiognomy than by chemical and physical attributes of the soil. In addition to the plant community, clay content, pH, Boron, P, S and CEC best explained some of the AMF community variables. Thus, we conclude that while several factors determine AMF community structure in the Atlantic Forest, phytophysiognomy is the most significant.

Resumo: O presente artigo apresenta algumas reflexões sobre o repertório desenvolvido no componente curricular Teclado e suas possíveis contribuições para a formação inicial de professores de música. Desenvolvido em aulas coletivas, parte do repertório é analisado e aplicado por meio de atividades realizadas no componente pertencente a matriz curricular do curso de Licenciatura em Música da Universidade Estadual de Feira de Santana. São objetos da análise três métodos: 1) Diorama de Cacilda Borges Barbosa (caderno preparatório); 2) 13 Pequenas Peças Brasileiras de Moema Craveiro Campos; 3) Miniaturas (peças para piano) de Maria da Graça Santos. Como resultado, verifica-se que o domínio de conhecimentos e práticas musicais é fundamental para o exercício docente na área, visto que o fazer musical é uma ferramenta essencial para o ensino de música. Todavia, o fazer musical deve ser ampliado a partir da articulação com saberes teóricos e pedagógicos musicais.

Abstract: This paper presents some thoughts on the repertoire developed in the curricular component keyboard and their contributions to the initial training of music teachers. Developed in group lessons, part of this repertoire is analyzed and applied through activities performed in the component pertaining to curriculum of the Bachelor's Degree in Music at the State University of Feira de Santana. They are objects of analysis three methods: 1) Diorama - Cacilda Borges Barbosa (preparatory documents); 2) 13 Small Parts Brazilian -Moema Craveiro Fields; 3) Miniatures (piano pieces) - Mary Grace Santos. As a result, it appears that the domain knowledge and musical practices is critical to the teaching practice in the area, as the music making is an essential tool for music education. However, music making was extended from the joint with theoretical knowledge.

AIM: To apply the Lamendin et al. (1992) technique on a Brazilian sample to assess its accuracy on this specific population. METHODS: The authors present two measurements in single-rooted teeth: the peridontosis and transparency of the root. Then, these variables are inserted in an equation to estimate the individual's age. The sample comprised 49 teeth obtained from the collection of the Forensic Medicine Institute of Guarulhos, Brazil. Statistical analysis was performed with t and paired t tests, comparing chronological and estimated ages. RESULTS: It was possible adjust the original formula for Brazilians by linear regression analysis: A = (P x 0.18) + (T x 0.47) + 31.77. Where, A = age; P = (periodontosis height x 100)/root height; and T = (transparency height x 100)/root height. CONCLUSIONS: The method is accurate only for young adults but it could be used with caution in individuals between 45 and 60 years of age to assist in estimating an age range. However, the technique loses its efficacy in older individuals.
