Environmental DNA: An emerging tool for understanding aquatic biodiversity
Trey Simmons, Damian M. Menning, Sandra L. Talbot
2020, Alaska Park Science (19)
Field surveys for aquatic organisms provide critical information that is important for robust resource management. However, such surveys are expensive and labor intensive, particularly in large, remote landscapes like those that characterize much of Alaska. Traditionally, characterizing aquatic biodiversity necessitated the physical capture and identification of individual organisms, which required...

Coming to terms with the new normal: Forest health in the Sierra Nevada
Jodi Axelson, John J. Battles, Adrian J. Das, Phillip J. van Mantgem
2020, Fremontia (47) 50-56
The vast conifer forests of California’s Sierra Nevada range inspire awe and create lasting memories. The size and longevity of these trees make them seem both otherworldly and everlasting. Indeed, their grandeur is such that visitors may not appreciate how these forests are connected to the larger landscape, and so...
Hydrologic monitoring networks in the Death Valley Regional Flow System, Nye County, Nevada and Inyo County, California
Steven R. Reiner, Peggy E. Elliott, Katherine J. Earp, Wayne R. Belcher
2020, Fact Sheet 2020-3018
IntroductionWater is an important resource in the arid southwest region of the United States where there is a limited supply of surface water and groundwater. In the Death Valley regional groundwater flow system (DVRFS) in southern Nevada and eastern California, groundwater is the main source of supply for agricultural, commercial,...
Combining models of the critical streakline and the cross-sectional distribution of juvenile salmon to predict fish routing at river junctions
Dalton Hance, Russell Perry, Jon R. Burau, Aaron R. Blake, Paul Stumpner, Xiaochun Wang, Adam Pope
2020, San Francisco Estuary and Watershed Science (18)
Because fish that enter the interior Delta have poorer survival than those emigrating via the Sacramento River, understanding the mechanisms that drive entrainment rates at side channel junctions is critically important for the management of imperiled juvenile salmon. Here, we implement a previously proposed process-based conceptual model to study entrainment...

A multiscale approach to understanding migratory land bird habitat use of functional stopover habitat types and management efforts
Theodore J. Zenzal Jr.
2020, Newsletter
It is hard to believe that many of the small “backyard birds” people see during spring and autumn can make migratory journeys that span thousands of kilometers. In fact, over two-thirds of all land birds (i.e., those not associated with aquatic habitats) and over half of the migratory species in...
Species and genetic diversity in Lake Huron in 2018
Wendylee Stott, Edward F. Roseman, Chris C. Wilson
2020, Special Publication 2020-01
Fish community objectives (FCOs) for species and genetic diversity (DesJardine et al. 1995) complement the species- or genera-specific objectives by recognizing that diversity within and among species can improve ecosystem resiliency through portfolio effects (DuFour et al. 2015). In Lake Huron, native species (such as Lake Trout and Lake Whitefish),...

2020, Report, 2019 Lake Ontario Unit Annual Report
In Lake Ontario, lake trout restoration efforts have not established a self-sustaining population. Herein we describe efforts to evaluate standard and new surveys, and to estimate dispersal from stocking locations, to better understand impediments to natural reproduction. In 2019, lake trout egg deposition was sampled at two locations, Stony Island...

Behavior, size, and body condition predict susceptibility to management and reflect post-treatment frequency shifts in an invasive snake
Melia G. Nafus, Amy A. Yackel Adams, S. M. Boback, Siers, Robert Reed
2020, Global Ecology and Conservatuin (21)
Foraging behavior can have population-level effects that are of interest for wildlife management. For invasive species, foraging behavior has been tied to establishment ability and rate of spread and is generally of import in understanding invasion biology. A major method for controlling invasive vertebrates is using food-based baits as attractants....
