The Goliath frog uses its powerful back legs to escape from attackers. It can jump three metres (10 feet) in a single hop. That's the length of a car.
Development of Canopy Structure in Douglas-fir Forests of the Pacific Northwest
Understanding forest dynamics
The controlling influence of tree canopy structure on many functions of its ecosystem is now widely recognized. Tree canopies can influence the light environment, the way rain is intercepted, the three-dimensional distribution of leafy foliage and the understory microclimate. However, just how these effects develop through time and how they are influenced by canopy structure is still poorly understood. Researchers from the University of Washington and The Evergreen State College, Olympia, Washington, aim to provide the most comprehensive information available to date concerning the structural development of Douglas-fir forests. Results from the study will contribute to a greater understanding of the complex structure of these forests and will in turn aid the conservation of this biological diversity.
