This book was released on 1989 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revisao taxonomica do genero Kielmeyera Martius permitiu uma avaliacao detalhada das suas caracteristicas morfologicas. Este estudo mostra que especies de Kielmeyera sao bastantes diversificadas em seus caracteres vegetativos e florais. Dentro de todas as caracteristicas examinadas, em um total superior a quatro mil especimes herborizados, o habito e os caracteres vegetativos evidenciaram-se com o maior grau de diversidade. Neste trabalho, os atributos morfologicos externos sao considerados basicos para a identificacao e a classificacao das especies de Kielmeyera; todavia, informacoes suplementares oriundas de outras disciplinas auxiliaram na conclusoes alcancadas no tratamento taxonomico do genero. Variacoes na morfologia externa, no habito e na fenologia, intra-especificamente, sao topicos estudados pelo autor em frequentes e extensivos trabalhos de campo em inumeras e diferentes localidades brasileiras com o objetivo de analisar as especies in loco. Consequentemente, este estudo permitiu a observacao de populacoes naturais de muitas especies de Kielmeyera dentro dos seus parametros de distribuicoes geografica e ecologica. Em contraste as caracteristicas vegetativas, as flores exibem importantes e confiaveis caracteres morfologicos com valores diagnosticos e taxonomicos. A morfologia dos frutos de Kielmeyera e muito constante em quase a totalidade das especies. Nesta publicacao, as caracteristicas exomorficas em relacao a taxonomia do genero Kielmeyera estao apresentadas em detalhes.

Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book Precious Heritage written by Bruce A. Stein and published by Oxford University Press. This book was released on 2000-03-16 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
