Geologic framework and hydrogeology of the Rio Rico and Nogales 7.5’ quadrangles, upper Santa Cruz Basin, Arizona, with three-dimensional hydrogeologic model
William R. Page, Mark W. Bultman, D. Paco VanSistine, Christopher M. Menges, Floyd Gray, Michael P. Pantea
2018, Scientific Investigations Report 2018-5062
Rapid population growth and declining annual recharge to aquifers in the upper Santa Cruz Basin area of southern Arizona, have increased the demand for additional groundwater resources. This demand is predicted to escalate in the future because of higher temperatures, longer droughts, less aquifer recharge, and decreased river and stream...
Broad‐scale occurrence of a subsidized avian predator: reducing impacts of ravens on sage‐grouse and other sensitive prey
Shawn T. O’Neil, Peter S. Coates, Brianne E. Brussee, Pat J. Jackson, Kristy B. Howe, Ann M. Moser, Lee J. Foster, David J. Delehanty
2018, Journal of Applied Ecology (55) 2641-2652
Expanding human enterprise across remote environments impacts numerous wildlife species. Anthropogenic resources provide subsidies for generalist predators that can lead to cascading effects on prey species at lower trophic levels. A fundamental challenge for applied ecologists is to disentangle natural and anthropogenic influences on species occurrence, and subsequently develop spatially...

Carmine Donatelli, Neil Kamal Ganju, Sergio Fagherazzi, Nicoletta Leonardi
2018, Geophysical Research Letters (45) 4933-4943
Seagrasses are marine flowering plants that strongly impact their physical and biological surroundings and are therefore frequently referred to as ecological engineers. The effect of seagrasses on coastal bay resilience and sediment transport dynamics is understudied. Here we use six historical maps of seagrass distribution in Barnegat Bay, USA, to investigate...

Steven Gray, Alexey Voinov, Michael Paolisso, Rebecca Jordan, Todd BenDor, Pierre Bommel, Pierre D. Glynn, Beatrice Hedelin, Klaus Hubacek, Josh Introne, Nagesh Kolagani, Bethany Laursen, Christina Prell, Laura Schmitt-Olabisi, Alison Singer, Eleanor J. Sterling, Moira Zellner
2018, Ecological Applications (28) 46-61
Including stakeholders in environmental model building and analysis is an increasingly popular approach to understanding ecological change. This is because stakeholders often hold valuable knowledge about socio-environmental dynamics and collaborative forms of modeling produce important boundary objects used to collectively reason about environmental problems. Although the number of participatory modeling...
The influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware
Melanie K. Vanderhoof, Hayley Distler, Megan W. Lang, Laurie C. Alexander
2018, Wetlands Ecology and Management (26) 63-86
The dependence of downstream waters on upstream ecosystems necessitates an improved understanding of watershed-scale hydrological interactions including connections between wetlands and streams. An evaluation of such connections is challenging when, (1) accurate and complete datasets of wetland and stream locations are often not available and (2) natural variability in surface-water...

Computer modelling for ecosystem service assessment
Robert Dunford, Paula A. Harrison, Kenneth J. Bagstad
2017, Book chapter, Mapping ecosystem services
Computer models are simplified representations of the environment that allow biophysical, ecological, and/or socio-economic characteristics to be quantified and explored. Modelling approaches differ from mapping approaches (Chapter 5) as (i) they are not forcibly spatial (although many models do produce spatial outputs); (ii) they focus on understanding and quantifying the...
