Trophic cascades linking wolves (Canis lupus), coyotes (Canis latrans), and small mammals

Creator:: Miller, Brian J., Harlow, Henry J., Harlow, Tyler S., Biggins, Dean, and Ripple, William J.
Abstract:: When large carnivores are extirpated from ecosystems that evolved with apex predators, these systems can change at the herbivore and plant trophic levels. Such changes across trophic levels are called cascading effects and they are very important to conservation. Studies on the effects of reintroduced wolves in Yellowstone National Park...

The hydrology of the humid tropics

Creator:: Wohl, Ellen, Barros, Ana, Brunsell, Nathaniel, Chappell, Nick A., Coe, Michael, Giambelluca, Thomas, Goldsmith, Steven, Harmon, Russell, Hendrickx, Jan M. H., Juvik, James, McDonnell, Jeffrey, and Ogden, Fred
Abstract:: Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth, land use and climate change will profoundly influence tropical hydrology, yet understanding of key hydrological interactions is limited. We propose that efforts...

The effect of elevated temperature exposure on the fracture toughness of solid wood and structural wood composites

Creator:: Sinha, Arijit, Nairn, John A., and Gupta, Rakesh
Abstract:: Fracture toughness of wood and wood composites has traditionally been characterized by a stress intensity factor, an initiation strain energy release rate (G[subscript init]) or a total energy to fracture (G[subscript f]). These parameters provide incomplete fracture characterization for these materials because the toughness changes as the crack propagates. Thus...

Revisiting the neutral axis in wood beams

Creator:: Davis, Philip M., Gupta, Rakesh, and Sinha, Arijit
Abstract:: For wood beams, it is often assumed that the neutral axis (NA) is located at the centroid of the beam. This would be the case for isotropic and homogeneous materials but these prerequisites are not valid for wood. The varying grain patterns and knots located throughout wood make wood anisotropic...
