Individual snag detection using neighborhood attribute filtered airborne lidar data

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., and Olsen, Michael J.
Abstract:: The ability to estimate and monitor standing dead trees (snags) has been difficult due to their irregular and sparse distribution, often requiring intensive sampling methods to obtain statistically significant estimates. This study presents a new method for estimating and monitoring snags using neighborhood attribute filtered airborne discrete-return lidar data. The...

Evaluating the influence of land use, drought and reach isolation on the occurrence of freshwater mussel species in the lower Flint River Basin, Georgia (U.S.A.)

Creator:: Shea, Colin P., Peterson, James T., Conroy, Michael J., and Wisniewski, Jason M.
Abstract:: North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...

Prediction of understory vegetation cover with airborne lidar in an interior ponderosa pine forest

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., Gitelman, Alix, and Olsen, Michael J.
Abstract:: Forest understory communities are important components in forest ecosystems providing wildlife habitat and influencing nutrient cycling, fuel loadings, fire behavior and tree species composition over time. One of the most widely utilized understory component metrics is understory vegetation cover, often used as a measure of vegetation abundance. To date, understory...

Factors influencing spawner success in a spring Chinook salmon (Oncorhynchus tshawytscha) reintroduction program

Creator:: Sard, Nicholas M., O'Malley, Kathleen G., Jacobson, Dave P., Hogansen, Michael J., Johnson, Marc A., and Banks, Michael A.
Abstract:: Dams have contributed to the decline of migratory fishes by blocking access to historical habitat. The active transport (trap and haul) of migratory fish species above existing dams can sometimes support population recovery when the use of fish ladders or dam removal is infeasible. However, little is known about the...

Photoacclimation of natural phytoplankton communities

Creator:: Graff, Jason R., Westberry, Toby K., Milligan, Allen J., Brown, Matthew B., Dall’Olmo, Giorgio, Reifel, Kristen M., and Behrenfeld, Michael J.
Abstract:: ABSTRACT: Phytoplankton regulate internal pigment concentrations in response to light and nutrient availability. Chlorophyll a to phytoplankton carbon ratios (chl:C phyto) are commonly reported as a function of growth irradiance (Eg) for evaluating the photoacclimation response of phytoplankton. In contrast to most culture experiments, natural phytoplankton communities experience fluctuating environmental...

Combining and aggregating environmental data for status and trend assessments: challenges and approaches

Creator:: Maas-Hebner, Kathleen G., Harte, Michael J., Molina, Nancy, Hughes, Robert M., Schreck, Carl, and Yeakley, J. Alan
Abstract:: Increasingly, natural resource management agencies and nongovernmental organizations are sharing monitoring data across geographic and jurisdictional boundaries. Doing so improves their abilities to assess local-, regional-, and landscape-level environmental conditions, particularly status and trends, and to improve their ability to make short-and long-term management decisions. Status monitoring assesses the current...

A Hybrid DNA Extraction Method for the Qualitative and Quantitative Assessment of Bacterial Communities from Poultry Production Samples

Creator:: Rothrock, Michael J., Jr., Hiett, Kelli L., Gamble, John, Caudill, Andrew C., Cicconi-Hogan, Kellie M., and Caporaso, J. Gregory
Abstract:: The efficacy of DNA extraction protocols can be highly dependent upon both the type of sample being investigated and the types of downstream analyses performed. Considering that the use of new bacterial community analysis techniques (e.g., microbiomics, metagenomics) is becoming more prevalent in the agricultural and environmental sciences and many...
