plastid matK phylogeny ,Caesalpinioideae ,[SDV]Life Sciences [q-bio] ,Cercidoideae ,mimosoid clade ,Papilionoideae ,Detarioideae ,Duparquetioideae ,Dialioideae - Abstract
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most widely sequenced across the legumes, and in most legume lineages, this gene region is sufficiently variable to yield well-supported clades. This analysis resolves the same major clades as in other phylogenies of whole plastid and nuclear gene sets (with much sparser taxon sampling). Our analysis improves upon previous studies that have used large phylogenies of the Leguminosae for addressing evolutionary questions, because it maximises generic sampling and provides a phylogenetic tree that is based on a fully curated set of sequences that are vouchered and taxonomically validated. The phylogenetic trees obtained and the underlying data are available to browse and download, facilitating subsequent analyses that require evolutionary trees. Here we propose a new community-endorsed classification of the family that reflects the phylogenetic structure that is consistently resolved and recognises six subfamilies in Leguminosae: a recircumscribed Caesalpinioideae DC., Cercidoideae Legume Phylogeny Working Group (stat. nov.), Detarioideae Burmeist., Dialioideae Legume Phylogeny Working Group (stat. nov.), Duparquetioideae Legume Phylogeny Working Group (stat. nov.), and Papilionoideae DC. The traditionally recognised subfamily Mimosoideae is a distinct clade nested within the recircumscribed Caesalpinioideae and is referred to informally as the mimosoid clade pending a forthcoming formal tribal and/or clade-based classification of the new Caesalpinioideae. We provide a key for subfamily identification, descriptions with diagnostic charactertistics for the subfamilies, figures illustrating their floral and fruit diversity, and lists of genera by subfamily. This new classification of Leguminosae represents a consensus view of the international legume systematics community; it invokes both compromise and practicality of use.

The pit membrane in bordered pits of conifer tracheids is characterized by a porous margo and central thickening (torus), which is traditionally considered to function as an impermeable safety valve against air-seeding. However, electron microscopy based on 33 conifer species, including five families and 19 genera, reveals that pores occur in the torus of 13 of the species studied. The pores have a plasmodesmatal origin with an average diameter of 51 nm and grouped arrangement. Evidence for embolism spreading via pores in tori is supported by the pore sizes, which correspond relatively well with the pressure inducing cavitation. Predictions based on earlier correlations between pit structure and cavitation resistance were only weakly supported for species with punctured tori. Moreover, species with punctured tori are significantly less resistant to cavitation than species with non-punctured tori. Nevertheless, absolute pore diameters must be treated with caution and correlations between theoretical and measured air-seeding pressures are weak. Because most pores appear not to traverse the torus but are limited to one torus pad, only complete pores would trigger air-seeding. Embolism spreading through a leaky torus is not universal across gymnosperms and unlikely to represent the only air-seeding mechanism.

(jurema-de-imbira), às vezes, ser confundida com Mimosa tenuiflora (Willd.) Poir. (jurema-preta) ou vice-versa, este trabalho objetivou apresentar novos dados referentes à anatomia e densidade básica da madeira das duas espécies, visando oferecer subsídio para identificação das duas espécies, identificar caracteres anatômicos da madeira relacionando-os com o ambiente caatinga e apresentar o potencial energético que sua madeira possui. O estudo anatômico e a determinação da densidade da madeira foram realizados com amostras ao nível do peito (1,30 m acima do solo) e em dois galhos com diferentes diâmetros, de espécimes ocorrentes nos municípios de Serra Talhada e Sertânia, Pernambuco, Brasil. As espécies apresentam distinção expressa através do tipo de casca, coloração do cerne e do alburno, além das características peculiares da madeira. Mimosa ophthalmocentra apresenta camadas de crescimento distintas, constituídas por linhas de parênquima axial contendo cristais, parênquima axial escasso e menor quantidade de raios por mm2. Já Mimosa tenuiflora apresenta camadas de crescimento distintas, porém sem cristais, parênquima axial vasicêntrico, em faixas ou aliforme confluente, e maior percentagem de raios. Ambas apresentam algumas estruturas da madeira com as características anatômicas comuns às diversas espécies do gênero Mimosa, contribuindo assim para uma melhor caracterização do gênero. Pelos parâmetros anatômicos da madeira e pela elevada densidade básica (>0,84 g/cm3), concluiu-se que as duas espécies apresentam perspectivas seguras para a produção de álcool combustível e carvão vegetal desde a fase de lenho juvenil. Mimosa ophthalmocentra apresenta maior potencial energético, pela maior percentagem de fibras e por possuir parênquima escasso e menor percentagem de raios. Feira de Santana

No. of bitstreams: 1 Silva, Lazaro Benedito da.pdf: 4693404 bytes, checksum: 982b50afec1db948d03e325eca4d95ce (MD5) Previous issue date: 2009-04 Este trabalho objetivou estudar a anatomia e a densidade básica da madeira de Caesalpinia pyramidalis utilizada pelas comunidades locais, ocorrente na caatinga de Pernambuco, nos municípios de Serra Talhada e Sertânia, assim como comparar a percentagem dos elementos do lenho no tronco e nos galhos, na própria árvore, a fim de estabelecer o potencial total do lenho para produção de energia. As amostras do lenho do tronco (DAP) e de ramos de seis árvores da espécie foram coletadas nos dois municípios acima citados, em 2002. As análises das amostras seguiram os métodos usualmente empregados em estudo de anatomia de madeiras. Pelos parâmetros anatômicos do lenho e a elevada densidade básica (>0,84 g/cm3), concluiu-se que Caesalpinia pyramidalis revela grande quantidade de celulose e lignina, portanto apresentou perspectivas seguras para produção de álcool combustível e carvão vegetal. Pode-se propor o uso do lenho do tronco e dos galhos como combustível, desde a fase jovem da madeira, pela grande concentração de fibras, menor concentração de vasos e menor quantidade de parênquima, nos espécimes dos dois municípios.

A demanda de uso energético da vegetação da Caatinga tem gerado modificações nas paisagens e perda de diversidade biológica por insuficiência de informações sobre o manejo das espécies. Considerando o fato da estacionalidade climática ser um fator de influência na sobrevivência, ritmo biológico, rebrota e produtividade das plantas, neste estudo objetivou-se avaliar a influência da sazonalidade climática sobre a sobrevivência e a produção de biomassa de Caesalpinia pyramidalis Tul. (Caesalpiniaceae). Para tal, foram selecionados aleatoriamente 180 indivíduos de C. pyramidalis, sendo estes distribuídos em três blocos de 1ha de caatinga (60 indivíduos por bloco). O delineamento experimental foi de blocos ao acaso com 6 tratamentos (sendo duas estações climáticas e três anos consecutivos de avaliação) para a avaliação da sobrevivência e com 4 tratamentos (duas estações climáticas e dois anos de medição) para a avaliação da biomassa aérea. As avaliações foram realizadas em duas estações: seca e chuvosa, sendo metade dos indivíduos de cada bloco (n = 30) submetidos à corte raso em cada uma das estações. Após o corte, a quantificação do peso fresco foi determinada em três componentes previamente definidos como lenha, estaca e graveto. As plantas foram monitoradas por 3 anos, sendo a sobrevivência anual registrada e a produção de biomassa da rebrota medida no último ano. A sobrevivência das plantas foi similar e elevada nos três anos, independente da estação climática. As plantas recém cortadas apresentaram elevado percentual de lenha e as rebrotas apresentaram elevado percentual de graveto. O tamanho inicial das plantas não esta relacionado à variação do peso fresco da rebrota. O estudo mostra que, apesar de ocorrer regeneração das plantas após corte raso, o tempo de três anos não é suficiente para recuperação da produção dos produtos madeireiros em C. pyramidalis, sendo necessário um tempo de repouso maior para um novo ciclo de corte, visando manter a produção da espécie para atender a demanda energética da população rural. The demand for wood fuel from caatinga vegetation has caused landscape modifications and loss of biodiversity due to insufficient information on species management. As seasonal climate influences plant survival, biological rhythm, regrowth and productivity, this study aimed to evaluate the influence of seasonality on the biological rhythm and biomass production of Caesalpinia pyramidalis Tul. (Caesalpiniaceae).A total of 180 individuals of C. pyramidalis were randomly selected, distributed in three blocks of 1 ha of caatinga (60 trees each). The experiment was arranged in a randomized block design with six treatments (two seasons and three consecutive evaluation years) for survival and four treatments (two seasons and two measurement years) for aerial biomass production. Measurements were carried out in two seasons: dry and wet, with half of the number of individuals in each block (n=30) being coppiced in each season. After cutting, fresh weight was determined for three components: fuel wood, posts and "twigs and leaves". The trees were monitored for three years, their survival monitored annually and regrowth biomass production measured in the last year. The survival of the trees was high and similar during the three years, independent of the season in which they were coppiced. When originally cut, the trees provided a high percentage of fuel wood and the regrowth provided a high percentage of "twigs and leaves". The original size of the trees does not explain the variation in regrowth fresh weight.. The study shows that, despite sprouting after coppicing, three years are not sufficient to provide adequate wood production in C. pyramidalis. A longer fallow period is necessary to guarantee sufficient growth to meet wood fuel demand of the rural population.
