ABSTRACT: The large amount of degraded areas and productive potential of the legal reserves in Brazil make restoration an environmental demand and a commercial opportunity. We modelled the diameter growth as a function of age of eight tree species in restoration plantations in the Brazilian Amazon. From 14 years of annual forest inventory data, for each species, we tested variations of logistic function: simple logistic, logistic with covariant (plant area at the time of planting), logistic with random effect, logistic with random effect and covariant. Amongst the studied species, Schizolobium parahyba var. amazonicum, Tectona grandis and Simarouba amara showed the highest growth rates while Cordia alliodora, Cedrela odorata and three species of the genus Handroanthus showed slower growth. The gains from using the covariant in modeling were small for both fixed and mixed-effect models. Gains from the inclusion of the random effect were substantial. Mixed-effect models had the best performance in modeling the growth of the species. Our results provide basis for a critical view of the criteria and possibilities for degraded areas restoration and management practices in legal reserves of the Amazon. An economic analysis is required to ensure the viability of these areas? sustainable exploitation. TÍTULO: Modelos de crescimento não linear para espécies de árvores usadas na restauração florestal no Arco do Desmatamento da Amazônia brasileira RESUMO: A grande quantidade de áreas degradadas e o potencial produtivo das reservas legais no Brasil tornam a restauração uma demanda ambiental e oportunidade comercial. Modelamos o crescimento do diâmetro em função da idade de oito espécies de árvores em plantações de recomposição na Amazônia brasileira. A partir de 14 anos de dados de inventário florestal anual, testamos variações da função logística: logística simples, logística com covariante (área da planta na época do plantio), logística com efeito aleatório, logística com efeito aleatório e covariante. As espécies Schizolobium parahyba var. amazonicum, Tectona grandis e Simarouba amara apresentaram as maiores taxas de crescimento, enquanto Cordia alliodora, Cedrela odorata e três espécies do gênero Handroanthus apresentaram crescimento mais lento. Os ganhos com o uso da covariante na modelagem foram pequenos para modelos de efeitos fixos e mistos. Os ganhos com a inclusão do efeito aleatório foram substanciais. Os modelos de efeitos mistos tiveram o melhor desempenho na modelagem do crescimento das espécies. Nossos resultados fornecem subsídios para uma visão crítica sobre os critérios, possibilidades de recomposição e práticas de manejo de áreas degradadas em reservas legais na Amazônia. Uma análise econômica é necessária para garantir a viabilidade da exploração sustentável dessas áreas.

Transposable elements are ubiquitous and constitute an important source of genetic variation in addition to generating deleterious mutations. Several filamentous fungi are able to defend against transposable elements using RIP(repeat-induced point mutation)-like mechanisms, which induce mutations in duplicated sequences. The sequenced Colletotrichum graminicola genome and the availability of transposable element databases provide an efficient approach for identifying and characterizing transposable elements in this fungus, which was the subject of this study. We identified 132 full-sized Tc1-Mariner transposable elements in the sequenced C. graminicola genome, which were divided into six families. Several putative transposases that have been found in these elements have conserved DDE motifs, but all are interrupted by stop codons. An in silico analysis showed evidence for RIP-generated mutations. The TCg1 element, which was cloned from the Brazilian 2908 m isolate, has a putative transposase sequence with three characteristic conserved motifs. However, this sequence is interrupted by five stop codons. Genomic DNA from various isolates was analyzed by hybridization with an internal region of TCg1. All of the isolates featured transposable elements that were similar to TCg1, and several hybridization profiles were identified. C. graminicola has many Tc1-Mariner transposable elements that have been degenerated by characteristic RIP mutations. It is unlikely that any of the characterized elements are autonomous in the sequenced isolate. The possible existence of active copies in field isolates from Brazil was shown. The TCg1 element is present in severalC. graminicola isolates and is a potentially useful molecular marker for population studies of this phytopathogen. Key words: RIP, transposase, transposon MenosTransposable elements are ubiquitous and constitute an important source of genetic variation in addition to generating deleterious mutations.
