Available in PDF, EPUB and Kindle. Book excerpt: A soja e uma leguminosa de grande importancia em virtude, principalmente, de seu elevado conteudo de oleo e proteina de grao. Nos anos agricolas 1995/96 e 1996/97, foram conduzidos dois experimentos - um a campo e outro em casa de vegetacao, na Universidade Estadual de Londrina, visando: (1) quantificar os teores de oleo e proteina em dois grupos de genotipos de soja, sendo que um grupo conduzido a campo foi constituido por 25 linhagens (geracoes F9 e F10), oriundas de topocruzamentos entre soja tipo alimento com dois testadores tipo grao: Doko e FT-2, alem das cultivares FT_Monsanto, Doko e FT-2, totalizando por 39 genotipos, entre cultivares e linhagens de soja tipo alimento; (2) estimar as correlacoes fenotipicas, genotipicas e de ambiente existentes entre os teores de oleo, proteina e tamanho das sementes, nesses genotipos; e, (3) identificar genotipos para consumo humano de forma direta, com elevado teor de proteina. O delineamento estatistico utilizado foi o de blocos casualizados com tres repeticoes, sendo que no experimento a campo cada repeticao foi constituida de uma linha de semeadura de 5m de comprimento e no experimento em casa de vegetacao constitui-se de um vaso com tres plantas. Foram avaliados os caracteres peso de Cem Sementes (PCS, expresso em gramas / 100 sementes), teor de oleo (TO), e teor de proteina (TP), expresso em %. Com base nas medias das parcelas (repeticoes), realizaram-se analises individuais de variancia para cada um dos dois anos avaliados e, tambem analises conjuntas. Visando verificar a existencia de diferencas significativas entre as medias dos tramentos, aplicou-se o teste de Duncan. Alem disso, estimaram-se as correlacoes existentes entre os tres caracteres e realizou-se o desdobramento da interacao entre tratamentos e anos. De um modo geral, os tratamentos apresentaram um baixa variabilidade para o caracteres TO e TP, e essa baixa variabilidade foi mais pronunciada para o carater TP entre os genotipos conduzidos a campo. A populacao conduzida a campo apresentou um teor de oleo de 16,62%, variando de 12 (GA22) a 20,37% (GA14), e um teor medio de proteina de 38,64%, variando de 35,66 (FT-2) a 41,75% (GA17). Ja a populacao conduzida em casa de vegetacao apresento um teor medio de proteina de 36,75% variando de 32,95 (Paranagoiana) a 41,56% (PI408251). Em casa de vegetacao, as correlacoes entre os teores de oleo e proteina foram negativas e significativas (r= -0,45**, rg= 0,65, para analise conjunta). Na analise conjunta, o tamanho das sementes apresentou correlacoes significativas e positivas com teor de oleo (Rf=0,20,rg=0,24), bem como, tambem, com o teor de proteina (rf=9,0,02, rg=0,04). Na condicao de casa de vegetacao, as analises individuais mostram que a relacao do peso de cem sementes com os teores de oleo e proteina foram baixas e muito afetadas pelos efeitos dos anos. Destacaram-se, dentre os tratamentos conduzidos a campo, GA23 E GA20; e, dentre os tratamentos conduzidos em casa de vegetacao, PI408251, Waseda, B6F4 (L-3 less), PI423909 e Tambagura, pelo elevado teor de proteina e pela estabilidade obtidas, principalmente em relacao aos teores de oelo e proteina.

This book was released on 2008 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: O elevado valor sócioeconômico da soja é atribuído, em grande parte, à combinação muito favorável de altos teores de proteína e óleo, juntamente com níveis adequados de produtividade de grãos. Porém, existe uma alta correlação negativa entre os teores de proteína e óleo, fato que dificulta o melhoramento simultâneo destes caracteres. Além disso, também existe tendência de correlação negativa e moderada entre o teor de proteína e a produtividade de grãos. Existem evidências de que a seleção para a densidade da semente pode promover ganhos indiretos simultâneos no teor de proteína e na produtividade de grãos. Assim, os principais objetivos deste trabalho foram: a) estimar parâmetros genéticos relacionados com a herança da densidade da semente; b) avaliar a eficiência da seleção para densidade da semente no melhoramento do teor de proteína e da produtividade de grãos. Para o estudo de herança foram utilizados quatro cruzamentos diferentes: USP98-06.011. x Abura, M-SOY 8001 x Abura, USP98-06.027.03 x Biloxi e USP98-06.009.01 x PI 239.235, sendo que os parentais e as plantas F 2 foram avaliados durante a safra 2006/07. Já para avaliar as respostas correlacionadas à seleção para densidade da semente foram delineados três experimentos distintos: Experimento Inicial, no qual foram avaliadas 520 progênies F 7:6, durante a safra 2005/06; Experimento Densidade, em que foram avaliadas 100 progênies F8:6 selecionadas para densidade da semente; Experimento Alimentos, em que foram avaliadas 100 progênies F8:6 selecionadas para soja tipo alimento. Os dois últimos experimentos foram realizados durante a safra 2006/07, e as progênies avaliadas neles foram selecionadas dentre as 520 progênies F7:6 do Experimento Inicial. Os resultados permitiram chegar as seguintes conclusões: a) existe ampla variabilidade genética para densidade da semente; b) a herdabilidade no sentido amplo para este caráter é baixa quando estimada na geração F2, mas em geração avançada de endogamia atinge valor alto; c) a herança genética é aditiva e, assim, o caráter não manifesta hereose; d) existe correlação moderada e positiva da densidade da semente com a produtividade de grãos e o teor de proteína e, por outro lado, a correlação entre a densidade da semente e o teor de óleo é negativa; e) é possível identificar genótipos tipo alimento com médias altas de produtividade de grãos e teor de proteína; f) a seleção para aumentar a densidade da semente é eficiente no melhoramento simultâneo do teor de proteína e da produtividade de grãos, permitindo a obtenção de genótipos com alta produtividade de proteína; g) a seleção para reduzir a densidade da semente não promove aumentos significativos do teor de óleo.

Available in PDF, EPUB and Kindle. Book excerpt: There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.

Book excerpt: Descended from a long and ancient lineage, tapirs are important tropical forest seed dispersers. However, today, all species of tapirs are threatened to various degrees by habitat destruction and hunting. This action plan was written with wildlife biologists, ecologists, administrators, educators and local conservation officials in mind and is aimed at those countries with tapir populations. It provides a brief natural history of each species and its objective is to aid in their conservation by catalyzing conservation action. In addition, it is hoped that the contents of the plan will stimulate further research into this fascinating group of animals.

This book was released on 2008-05-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to help identify major gaps in our knowledge of how gender and age affect psychiatric diagnoses and to stimulate much-needed research to fill these gaps, Age and Gender Considerations in Psychiatric Diagnosis serves as both a valuable short-term source for the DSM-V Task Force and its disorder-specific workgroups, and a long-term guide for future studies that will contribute to revised psychiatric classifications in these three areas. Here, 47 experts present findings in three areas of psychiatric research that historically have been neglected but rightfully have received increasing attention in recent years and thus are worthy of investigation into their clinical features, etiology, and course: 1. Significant gender differences in prevalence, symptom profiles, and risk factors for mental disorders, including neurodevelopmental, neurophysiological, and environmental factors for men and women that cut across diagnostic categories-for example, the critical importance of gender in how psychiatric illness develops and presents; DSM's approach to gender to date; and relevant research findings and gaps in the epidemiology, etiology, and pathophysiology of disorders and the gender-related expression of psychopathology, including the controversial and complex question of whether DSM should have different diagnostic criteria for men and women. 2. Mental disorders in infancy and early childhood, including diagnosis and measurement of psychopathology; PTSD and social and cognitive factors related to the experience of stress; reactive attachment disorder (unique in part because of its specificity to early childhood); mood and anxiety disorders and difficulties in diagnosis; sleep disorders, including two new disorders, Night-Waking Dysomnia and Sleep-Onset Dysomnia; feeding disorders, including the need to address overeating and overfeeding (especially given the alleged U.S. epidemic of obesity); early childhood manifestations of behavior disorders; and early symptoms and diagnosis of autism. 3. Mental disorders in the elderly, such as dementia and depression, once considered normal consequences of aging but now understood to represent mental disorders, including the need to identify specific brain structure abnormalities, biomarkers, and the many contributing biological, psychosocial, and environmental factors of mental illness in late life and to understand their roles in the elderly to better diagnose and monitor disease progression. Written for clinicians and researchers alike, this thought-provoking compendium contributes critical information that helps enhance our understanding of the causes of mental disorders, develop effective preventive and treatment interventions, and inform future editions of DSM and ICD.
