Ecosystem implications of conserving endemic versus eradicating introduced large herbivores in the Galapagos Archipelago
Guillaume Bastille-Rousseau, James P. Gibbs, Karl Campbell, Charles B. Yackulic, Stephen Blake
2017, Biological Conservation (209) 1-10
Restoration of damaged ecosystems through invasive species removal and native species conservation is an increasingly common practice in biodiversity conservation. Estimating the degree of ecosystem response attributable specifically to eradication of exotic herbivores versus restoration of native herbivores is often difficult and is complicated by concurrent temporal changes in other...
Climate change and the eco-hydrology of fire: Will area burned increase in a warming western USA?
Donald McKenzie, Jeremy S. Littell
2017, Ecological Applications (27) 26-36
Wildfire area is predicted to increase with global warming. Empirical statistical models and process-based simulations agree almost universally. The key relationship for this unanimity, observed at multiple spatial and temporal scales, is between drought and fire. Predictive models often focus on ecosystems in which this relationship appears to be particularly...

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...
Improving the Hawaiian seismic network for earthquake early warning
Alicia Hotovec-Ellis, Paul Bodin, Weston Thelen, P. Okubo, John E. Vidale
2017, Seismological Research Letters (88) 326-334
The motivation for earthquake early warning (EEW) is the fact that in many applications a few extra seconds of notice ahead of the about-imminent strong shaking can provide significant benefit. Reducing data latencies, accelerating processing times, and tuning seismic station distributions increase...

Experts correctly describe demography associated with historical decline of the endangered Indiana bat, but not recent period of stationarity
Wayne E. Thogmartin, Carol A. Sanders-Reed, Jennifer Szymanski, Lori Pruitt, Michael C. Runge
2017, PeerJ (5)
Demographic characteristics of bats are often insufficiently described for modeling populations. In data poor situations, experts are often relied upon for characterizing ecological systems. In concert with the development of a matrix model describing Indiana bat (Myotis sodalis) demography, we elicited estimates for parameterizing this model from 12 experts. We...
Electrical resistivity investigation of fluvial geomorphology to evaluate potential seepage conduits to agricultural lands along the San Joaquin River, Merced County, California, 2012–13
Krishangi D. Groover, Matthew K. Burgess, James F. Howle, Steven P. Phillips
2017, Scientific Investigations Report 2016-5172
Increased flows in the San Joaquin River, part of the San Joaquin River Restoration Program, are designed to help restore fish populations. However, increased seepage losses could result from these higher restoration flows, which could exacerbate existing drainage problems in neighboring agricultural lands and potentially damage crops. Channel deposits of...

Comparing stream-specific to generalized temperature models to guide salmonid management in a changing climate
Andrew K. Carlson, William W. Taylor, Kelsey M. Hartikainen, Dana M. Infante, Beard Jr., Abigail Lynch
2017, Reviews in Fish Biology and Fisheries (2) 443-462
Global climate change is predicted to increase air and stream temperatures and alter thermal habitat suitability for growth and survival of coldwater fishes, including brook charr (Salvelinus fontinalis), brown trout (Salmo trutta), and rainbow trout (Oncorhynchus mykiss). In a changing climate, accurate stream temperature modeling is increasingly important for sustainable...

Nonlethal laparoscopic detection of intersex (testicular oocytes) in largemouthbass (Micropterus salmoides) and smallmouth bass (Micropterus dolomieu)
Vicki S. Blazer, Alexander H Macleod, Mark A Matsche, Lance T Yonkos
2017, Environmental Toxicology and Chemistry (36) 1924-1933
Intersex in wild fish populations has received considerable attention in the scientific literature and public media. Conventional detection of testicular oocytes (TO), the presence of immature oocytes within testis of male fish, employs transverse sectioning of excised testis and is lethal. This present study used a non-lethal laparoscopic technique to...
