Energetic and health effects of protein overconsumption constrain dietary adaptation in an apex predator
Karyn D. Rode, Charles T. Robbins, Craig A. Stricker, Brian D. Taras, Troy N Tollefson
2021, Scientific Reports (11)
Studies of predator feeding ecology commonly focus on energy intake. However, captive predators have been documented to selectively feed to optimize macronutrient intake. As many apex predators experience environmental changes that affect prey availability, limitations on selective feeding can affect energetics and health. We estimated the...

2021, Movement Ecology (9)
BackgroundReintroducing predators is a promising conservation tool to help remedy human-caused ecosystem changes. However, the growth and spread of a reintroduced population is a spatiotemporal process that is driven by a suite of factors, such as habitat change, human activity, and prey availability. Sea otters (Enhydra lutris) are...

Trait heritability and its implications for the management of an invasive vertebrate
Brenna A Levine, Marlis R Douglas, Amy A. Yackel Adams, Bjorn Lardner, Robert Reed, Julie A. Savidge, Michael E Douglas
2021, Biological Invasions
Control methods that target specific traits of an invasive species can produce results contrary to the aims of management. If targeted phenotypes exhibit heritability, then it follows that the invasive species could evolve greater resistance to the applied control measures over time. Additional complications emerge if those traits targeted by...

Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear whether all phenophases, particularly those later in the season, will shift in unison or respond divergently to warming. Here,...

2021, Restoration Ecology
Riparian habitat in the southwestern USA has undergone substantial degradation over the past century, prompting extensive management and restoration of these critical ecosystems. Most restoration efforts, however, do not account for life history traits or riverine complexity that may influence genetic diversity and structure. Here, we use simple sequence repeat...

Historical effective population size of North American hoary bat (Lasiurus cinereus) and challenges to estimating trends in contemporary effective breeding population size from archived samples
Robert S. Cornman, Jennifer A. Fike, Sara J. Oyler-McCance, Paul M. Cryan
2021, PeerJ (9)
BackgroundHoary bats (Lasiurus cinereus) are among the bat species most commonly killed by wind turbine strikes in the midwestern United States. The impact of this mortality on species census size is not understood, due in part to the difficulty of estimating population size for this highly migratory and elusive...
Long‐term surveys support declines in early‐season forest plants used by bumble bees
John Michael Mola, Leif L Richardson, Greg Spyreas, David N. Zaya, Ian Pearse
2021, Journal of Applied Ecology
Populations of bumble bees and other pollinators have declined over the past several decades due to numerous threats, including habitat loss and degradation. However, we can rarely investigate the role of resource loss due to a lack of detailed long‐term records of forage plants and habitats.We use 22‐year repeated...
Surface material and snout-vent length predict vertical scaling ability in brown treesnakes:an evaluation of multispecies barriers for invasive species control on Guam
Eric T. Hileman, DR Bradke, Melia G. Nafus, Amy A. Yackel Adams, Robert Reed
2021, Management of Biological Invasions. (12) 476-494
The combination of snake-proof barriers and an aerial toxicant delivery system for snake suppression may allow large-scale control of invasive brown treesnakes (Boiga irregularis) on Guam. However, suppression or local eradication of several other species (e.g., introduced ungulates, cats, rodents) may be required for successful restoration and recovery of forest...
Investigating vegetation responses to underground nuclear explosions through integrated analyses

2021, Journal of Geophysical Research Biogeosciences (126)
Vegetation has the potential to respond to underground nuclear explosions, yet these links have not been fully explored. Given the lack of previously described signatures, the changes in vegetation are possibly subtle. The integration of multiple different data streams is potentially a useful approach to improve...

Impact of "non-lethal" tarsal clipping on bumble bees (Bombus vosnesenskii) may depend on queen stage and worker size
John Michael Mola, Clara Stuligross, Maureen L. Page, Danielle Rutkowski, Neal M. Williams
2021, Journal of Insect Conservation (25) 195-201
Recent bumble bee declines have prompted the development of novel population monitoring tools, including the use of putatively non-lethal tarsal clipping to obtain genetic material. However, the potential side effects of tarsal clipping have only been tested in the worker caste of a single domesticated species, prompting the need to...
Using enclosed Y-mazes to assess chemosensory behavior in reptiles
M. Rockwell Parker, Andrea Faye Currylow, Eric A. Tillman, Charlotte J. Robinson, Jillian Maureen Josimovich, Isabella M.G. Bukovich, Lauren A. Nazarian, Melia G. Nafus, Bryan M. Kluever, Amy A. Yackel Adams
2021, Journal of Visualized Experiments (170)
Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scent-trailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic...

Pamela L. Nagler, Julia B. Hull, Charles van Riper III, Patrick B. Shafroth, Charles B. Yackulic
2021, Fact Sheet 2020-3061
Tamarix spp. (tamarisk or saltcedar), a shrub-like tree, was intentionally introduced to the U.S. from Asia in the mid-1800s. Tamarisk thrives in today’s human-altered streamside (riparian) habitats and can be found along wetlands, rivers, lakes, and streams across the western U.S. In 2001, a biological control agent, Diorhabda spp. (tamarisk...
