Lidar is able to provide height and cover information which can be used to estimate selected forest attributes precisely. However, for users to evaluate whether the additional cost and complication associated with using Lidar merits adoption requires that the protocol to use lidar be thoroughly described and that a basis...
As remote sensing data continues to proliferate, development and assessment of methods that generate predictions of forest attributes is needed to inform operational use. For several decades, lidar data collected from aerial platforms has informed assessments of forest resources, but many opportunities remain for the technology. We examine and develop...
One of the most common practices regarding estimation of forest attributes is
the partitioning of large forested subpopulations into smaller areas of interest to
coincide with specific objectives of present and future forest management. New
estimators are needed to improve estimation of selected forest attributes in small areas
where the...
Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...
Skeletal muscle, the largest organ in the body in mass, is composed by 600 specialized muscles in humans with unique biochemical, physiological and metabolic identities. Skeletal muscles control body movement, locomotion, and nutrient balance. Muscle formation requires precisely orchestrated environmental signals and regulatory gene networks in time and space. Gene...
The issue of global climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of quantifying forest biomass in recent years. The official U.S. forest carbon reporting is based on the forest biomass estimates...
Airborne discrete-return lidar is an active remote sensing technology capable of obtaining accurate, fine-resolution three-dimensional measurements over large areas. Discrete-return lidar data produce three-dimensional object characterizations in the form of point clouds defined by precise x, y and z coordinates. The data also provide intensity values for each point that...
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
Historically, the difficulty of obtaining pure cultures of abundant marine
microbial plankton has an obstacle to reconstructing the underlying
mechanisms of biogeochemistry in the ocean. While a number of dominant
marine species from the ocean surface have been cultured, the dominant
microbial plankton of the dark ocean proved far more...
This qualitative study explored the gendered professional experiences of male elementary school counselors. The participants or co-researchers were twelve men of varied ethnic and racial backgrounds between 25 and 60 years old. They lived and worked in five US states in urban, suburban and rural settings. They provided school counseling...
