Fire and insects are natural disturbance agents in many forest ecosystems, often interacting to affect succession, nutrient cycling, and forest species composition. We review literature pertaining to effects of fire-insect interactions on ecological succession, use of prescribed fire for insect pest control, and effects of fire on insect diversity from northern and boreal forests in North Ameri...
This study aims to introduce the potential applicability of traditional ecological knowledge and community forestry in Northeast Asia, including China, Japan, and South Korea. In ancient Northeast Asia, forest policies and practices were based on Fengshui (an old Chinese concept regarding the flow of vital forces), with which forests were managed under community forestry. However, these traditi...
The 21”’ century continues a trend of rapid growth in both international trade of forest products and a concern for forests. These two trends are connected. Forces causing trade growth are linked to the loss of native forest resources in some countries and the accumulation of nonnative forest resources in other countries. Factors increasing trade include relaxation of trade barriers, income gro...
Organized by three distinguished members of the JBS Editorial Board – Marc Bickle, PhD, of the Max Planck Institute of Molecular Cell Biology and Genetics (Germany); Hakim Djaballah, PhD, of Institut Pasteur Korea (South Korea); and Lorenz Martin Mayr, PhD, of AstraZeneca (UK) – this special issue demonstrates how RNAi is enjoying a revival of popularity and is increasingly being applied to dis...
Traditionally Land Use Cover Change (LUCC) studies have focused on processes of negative land-cover change, primarily deforestation, partially because examples of positive land-cover change were not common. During the last two decades an outstanding tropical dry forest restoration process had taken place in the province of Guanacaste, Costa Rica, which has given us a unique opportunity to study...
We present a historical overview of forest concepts and definitions, linking these changes with distinct perspectives and management objectives. Policies dealing with a broad range of forest issues are often based on definitions created for the purpose of assessing global forest stocks, which do not distinguish between natural and planted forests or reforests, and which have not proved useful i...
Quantifying the amount of forest and change in the amount of forest are key to ensure that appropriate management practices and policies are in place to maintain the array of ecosystem services provided by forests. There are a range of analytical techniques and data available to estimate these forest parameters, however, not all ‘forest’ is the same and various components of change have been pr...
At one time, JEAB editorial policy was perceived by some to consist mainly of dogmatically enforcing a Skinnerian interpretation of all findings reported in the journal. Partly in response to that undeserved reputation, the journal explicitly defined itself as the place to publish research on the behavior of individual organisms, and not as a place that encourages any particular theoretical ori...
