A viabilidade técnica de plantios comerciais de Calophyllum brasiliense Cambess. foi avaliada na empresa JAMP Agropecuária e Reflorestadora Ltda. no município de Dueré, estado do Tocantins no período de 2009 a 2014 a partir da instalação de um inventário florestal sistemático contínuo. Foramamostrados 384 indivíduos em 35 ha distribuídos em 96 subparelas (0,96% de intensidade amostral) de 32m2. O plantio apresentou baixa variabilidade (CV < 20%) para variável HT (CV = 14,82%) e para variável DAP (CV= 18,60%) aos 74 meses de idade. Também apresentou distribuição normal defrequência (≥ 68% dois indivíduos devem estar entre o intervalo de mais ou menos um desvio padrão da ...
Os mosquitos constituem o grupo com maior capacidade vetorial de patógenos entre os artrópodes hematófagos. Dentre os de importância médica, as Mansonia spp. e as Coquillettidia spp. demonstram serem vetores potenciais de diversos arbovírus associados a doenças humanas em várias regiões do mundo. A presente tese está estruturada em cinco capítulos e teve como objetivo estudar a bioecologia e morfologia de mosquitos com ênfase na tribo Mansoniini em áreas do aproveitamento hidrelétrico na Amazônia – UHE – JIRAU, no estado de Rondônia, Brasil. Para captura dos adultos de Culicidae, utilizamos capturador de Castro, aspiradores movidos a bateria, armadilhas luminosas do tipo ...

This book is intended to provide an overview for the identification and establishment of biodiversity islands. It presents examples and case studies where the biodiversity islands approach is being used in a variety of locations and contexts worldwide. It will contribute to design parameters on appropriate sizing and spatial distribution of biodiversity islands in order to be effective in conservation and regeneration across the landscape, using integrated landscape management approaches. This book is essential given the current worldwide trend of habitat destruction and the need to preserve biodiversity and its values. The chapters are organized in five sections. The first section provides ...
This book integrates the latest global developments in forestry science and practice and their relevance for the sustainable management of tropical forests. The influence of social dimensions on the development of silvicultural concepts is another spotlight. Ecology and silvicultural options form all tropical continents, and forest formations from dry to moist forests and from lowland to mountain forests are covered. Review chapters which guide readers through this complex subject integrate numerous illustrative and quantitative case studies by experts from all over the world. On the basis of a cross-sectional evaluation of the case studies presented, the authors put forward possible silvicultural contributions towards sustainability in a changing world. The book is addressed to a broad readership from forestry and environmental disciplines.
This book focuses on the importance of human antimicrobial peptides (AMP) in keeping the host healthy and preventing infectious diseases. The first chapters deal with several examples of the role of AMP in different epithelial organs (skin and wound healing, eye, lung, genito-urinary tract, gut), which are exposed to different kinds of infectious microorganisms and as a result produce different patterns of AMP. Examples of the dysregulation of AMP expression and function promoting infections are discussed. The capacity of AMP to restrict the availability of essential metals to bacteria as an efficient antibacterial strategy in nutritional immunity is discussed in the next chapter. Our current understanding of how vitamin D, the sunshine vitamin, influences AMP-expression and how this can affect our health is also addressed. Last but not least, the role of AMP in HIV infection and the immunomodulatory properties of AMP highlight the diverse facets of AMP in host immunity. AMP’s specific functions, including in fighting multi-resistant bacteria, suggest that they may offer therapeutic benefits – a question that is discussed in the final chapter.
