Jessica M. Driscoll, Justin T. Brandt
2017, Scientific Investigations Report 2017-5057
The Albuquerque Bernalillo County Water Utility Authority (ABCWUA) drinking water supply was almost exclusively sourced from groundwater from within the Albuquerque Basin before 2008. In 2008, the San Juan-Chama Drinking Water Project (SJCDWP) provided surface-water resources to augment the groundwater supply, allowing for a reduction in groundwater pumping in the...
Genetic differentiation and inferred dynamics of a hybrid zone between Northern Spotted Owls (Strix occidentalis caurina) and California Spotted Owls (S. o. occidentalis) in northern California
Mark P. Miller, Thomas D. Mullins, Eric D. Forsman, Susan M. Haig
2017, Ecology and Evolution (7) 6871-6883
Genetic differentiation among Spotted Owl (Strix occidentalis) subspecies has been established in prior studies. These investigations also provided evidence for introgression and hybridization among taxa but were limited by a lack of samples from geographic regions where subspecies came into close contact. We analyzed new sets of samples from Northern...

Mark Erik Hansen, Nancy T. DeWitt, Billy J. Reynolds
2017, Data Series 1031
DescriptionLand development and alterations of the ecosystem in south Florida over the past 100 years have decreased freshwater and increased nutrient flows into many of Florida's estuaries, bays, and coastal regions. As a result, there has been a decrease in the water quality in many of these critical habitats, often...

Peter S. Coates, Brian G. Prochazka, Mark A. Ricca, Gregory T. Wann, Cameron L. Aldridge, Steven E. Hanser, Kevin Doherty, Michael S. O’Donnell, David R. Edmunds, Shawn P. Espinosa
2017, Open-File Report 2017-1089
Population ecologists have long recognized the importance of ecological scale in understanding processes that guide observed demographic patterns for wildlife species. However, directly incorporating spatial and temporal scale into monitoring strategies that detect whether trajectories are driven by local or regional factors is challenging and rarely implemented. Identifying the...
