In the UK, National Tree Week (26 November – 4 December) celebrates tree planting within local communities. The latest BES cross-journal Virtual Issue contains recent papers that highlight the global importance of trees and forests as habitat – for species from insects to primates – and in meeting human needs for fuel and agriculture. The selected papers also demonstrate novel methods scientists are using to study trees and forests.
National Tree Week is the UK’s largest tree celebration. It was started in 1975 by the Tree Council and has grown into an event that brings hundreds of organisations together to mark the beginning of Britain’s winter tree planting season.
Landscape connectivity is important for the ecology and genetics of populations threatened by climate change and habitat fragmentation. To begin our Virtual Issue Rayfield et al. present a method for identifying a multipurpose network of forest patches that promotes both short- and long-range connectivity. Their approach can be tailored to local, regional and continental conservation initiatives to protect essential species movements that will allow biodiversity to persist in a changing climate. The authors illustrate their method in the agroecosystem bordered by the Laurentian and Appalachian mountain ranges, that surrounds Montreal.
Basic Techniques for the Arborist Throw-line Launcher
The first of the three videos is a basic overview of the method. In this tutorial, the authors teach you how to find the ideal branch, how to use the throw-line launcher and go through some important safety information. Continue reading →
Seed predation plays an important role in global plant demography. In this video, Adam Davis, of the University of Illinois, demonstrates how field experiments and statistical models can can enable the extrapolation of long-term seed predation rates from short-term data.
