Animal movement models with mechanistic selection functions
Mevin Hooten, Xinyi Lu, Martha J. Garlick, James A. Powell
2020, Spatial Statistics (37)
A suite of statistical methods are used to study animal movement. Most of these methods treat animal trajectory data in one of three ways: as discrete pro- cesses, as continuous processes, or as point processes. We brie y review each of these approaches and then focus in on the latter. In the context of...
Lesser prairie-chicken (Tympanuchus pallidicinctus) use of man-made water sources
Trevor S. Gicklhorn, Clint W. Boal, Philip K. Borsdorf
2020, Southwestern Naturalist (65) 197-204
The lesser prairie-chicken (Tympanuchus pallidicinctus) occurs in the semiarid southern Great Plains, a region prone to periods of drought. Researchers generally believe that lesser prairie-chickens are able to satisfy their water requirements through preformed water and metabolic processes, but also know that they experience low survival and reproductive success during...

Abigail Jean Lawson, Brian Folt, Anna Maureen Tucker, Francesca T. Erickson, Conor P. McGowan
2020, Conservation Biology 1683-1685
Population viability analysis (PVA) is a widely used tool that applies demographic data in simulation frameworks to assess extinction risk for species or populations. It is used in diverse conservation applications, including evaluating management effectiveness, relative risk of threats, and potential changes to protective status (Beissinger & McCullough, <a id="#cobi13818-bib-0002R" class="bibLink...

Debris-flow growth in Puerto Rico during Hurricane Maria: Preliminary results from analyses of pre- and post-event lidar data
Jeffrey A. Coe, Erin K. Bessette-Kirton, Dianne L. Brien, Mark E. Reid
2020, Conference Paper, Proceedings of the 13th International Symposium on Landslides
On September 20, 2017, Hurricane Maria triggered widespread debris flows in Puerto Rico. We used field observations and pre- and post-Maria lidar to study the volumetric growth of long-travelled (>400 m) debris flows in four basins. We found overall growth rates that ranged from 0.7 to 30.4 m3 per meter...
Mapping Phragmites australis live fractional cover in the lower Mississippi River Delta, Louisiana
Amina Rangoonwala, Rebecca J. Howard, Elijah W. Ramsey III
2020, Open-File Report 2020-1131
In response to a co-occurring non-native scale infestation and Phragmites australis dieback in southeast Louisiana, normalized difference vegetation index (NDVI) satellite mapping was implemented to track P. australis condition in the lower Mississippi River Delta. While the NDVI mapping successfully documented relative condition changes, identification of cause required a quantitative-biophysical...
Reptiles under the conservation umbrella of the greater sage‐grouse
David S. Pilliod, Michelle I. Jeffries, Robert Arkle, Deanna H. Olson
2020, Journal of Wildlife Management (84) 478-491
In conservation paradigms, management actions for umbrella species also benefit co‐occurring species because of overlapping ranges and similar habitat associations. The greater sage‐grouse (Centrocercus urophasianus) is an umbrella species because it occurs across vast sagebrush ecosystems of western North America and is the recipient of extensive...

Brian D Peer, Barbara E. Kus, Mary J. Whitfield, Linnea S. Hall, Stephen I Rothstein
2020, Human-Wildlife Interactions (14)
The brown-headed cowbird (Molothrus ater; cowbird) is unique among North American blackbirds (Icteridae) because it is managed to mitigate the negative effects on endangered songbirds and economic losses in agricultural crops. Cowbird brood parasitism can further affect species that are considered threatened or endangered due to anthropogenic land...

Underwater photographic reconnaissance and habitat data collection in the Florida Keys—A procedure for ground truthing remotely sensed bathymetric data
Zachery W. Fehr, Kimberly K. Yates
2020, Open-File Report 2020-1118
Bathymetric geoprocessing analyses of the Florida Reef Tract have provided insights into trends of seafloor accretion and seafloor erosion over time and following major storm events. However, bathymetric surveys sometimes capture manmade structures and vegetation, which do not represent the desired bare-earth data. Therefore, ground truthing is essential to maintain...
