Book Description
Previous studies have reported that moths of the Geometridae family are good candidates for determining the effect of forestry practices on moth diversity because of their weak flight ability and high habitat fidelity. This report examines a red spruce forest site in New Brunswick on a plot by plot basis to determine the effect of silvicultural prescriptions on insect diversity as exemplified by the community of Geometridae. The objective was to compare species richness, abundance, diversity statistics, and complementarity of the geometrid fauna of an uncut plot with similar data from plots that had undergone silvicultural prescriptions. Results are presented & compared among plots that were subjected to selection cutting, strip cutting, and clear-cutting.

Book Description
This volume represents a uniquely comprehensive overview of our current knowledge on tropical montane cloud forests. 72 chapters cover a wide spectrum of topics including cloud forest distribution, climate, soils, biodiversity, hydrological processes, hydrochemistry and water quality, climate change impacts, and cloud forest conservation, management, and restoration. The final chapter presents a major synthesis by some of the world's leading cloud forest researchers, which summarizes our current knowledge and considers the sustainability of these forests in an ever-changing world. This book presents state-of-the-art knowledge concerning cloud forest occurrence and status, as well as the biological and hydrological value of these unique forests. The presentation is academic but with a firm practical emphasis. It will serve as a core reference for academic researchers and students of environmental science and ecology, as well as practitioners (natural resources management, forest conservation) and decision makers at local, national, and international levels.

Book Description
This report describes a study conducted as part of research on biota associated with specific forest successional stages and, in particular, to identify taxa that might be strongly linked to old stands. Lepidoptera were chosen for the study because they serve important roles as herbivores, pollinators, & prey; are easily collected; are sensitive to forest disturbances; and are well enough known taxonomically for their diversity to be assessed. A baseline examination of this assemblage was carried out in a mature stand and an old stand near Lac La Biche, Alberta. Comparisons between the two stands are made with regard to temporal & within-stand variability in moth species composition, variability associated with stand age, & species associated with a particular stand. In addition, the potential for Lepidoptera and its taxonomic sub-groups to serve as biodiversity indicators in the boreal forest was examined.

Book Description
The green-striped mapleworm. (Anisota rubicunda (Fab.)), a native of North America, is distributed widely throughout the eastern half of the United States and the southern parts of adjacent Canadian Provinces. Its southern range extends from the Carolina coast to the gulf coast in Alabama and Mississippi. It has been recorded as far west as Nebraska and Kansas. The insect causes heavy defoliation throughout its range but is most destructive near its southwestern limits.

Book Description
This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Book Description
"The management of tropical forest ecosystems is essential to the health of the planet. This book addresses forest insect pest problems across the world's tropics, addressing the pests' ecology, impact and possible approaches for their control. Fully updated, this second edition also includes discussions of new areas of interest including climate change, invasive species, forest health and plant clinics. This work is an indispensible resource for students, researchers and practitioners of forestry, ecology, pest management and entomology in tropical and subtropical countries."--pub. desc.
