Managing wildlands to protect species and ecosystem services in response to climate change is challenging. To develop effective long-term strategies, natural resource managers need to account for the projected effects of climate change as well as the uncertainty inherent in those projections. Vegetation models are one important source of projected...
The potential evapotranspiration (PET) that would occur with unlimited plant access to water is a central
driver of simulated plant growth in many ecological models. PET is influenced by solar and longwave
radiation, temperature, wind speed, and humidity, but it is often modeled as a function of temperature
alone. This...
The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and...
Distance learning enables students to study effectively from remote locations. With
televised lectures now commonplace, many disciplines can provide effective distance
learning. While the lecture format serves many disciplines, it does not serve those that
require laboratory work. Currently, there is little distance learning support for laboratory
work.
Second Best...
Large shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future...
Crops were grown at the experimental farms using accepted cultural practices within the limits of experimentation or trials were conducted on growers' field. Most experiments were designed as randomized complete blocks with two to five replications. Herbicide treatments were applied uniformly with equipment ranging from precision plot sprayers to quart...
Recent developments in estimation of the survivability of a U.S. Navy transport barge in random seas are extended to improve accuracy. The single Degree-of-Freedom (DOF) model of a extreme roll response of a barge used in previous research is replaced by a 3-DOF roll-heave-sway model to include linear and nonlinear...
