Assessing the performance of index calibration survey methods to monitor populations of wide-ranging low-density carnivores

Egil Droge, Scott Creel, Matthew Becker, Andrew Loveridge, Lara Sousa & David Macdonald
Apex carnivores are wide-ranging, low-density, hard to detect, and declining throughout most of their range, making population monitoring both critical and challenging. Rapid and inexpensive index calibration survey (ICS) methods have been developed to monitor large African carnivores. ICS methods assume constant detection probability and a predictable relationship between the index and the actual population of interest. The precision and utility of the resulting estimates from ICS methods have been questioned. We assessed the performance...

An improved understanding of ungulate population dynamics using count data: insights from western Montana

Terrill Paterson, Kelly Proffitt, Jay Rotella & Robert Garrott
Understanding the dynamics of ungulate populations is critical given their ecological and economic importance. In particular, the ability to evaluate the evidence for potential drivers of variation in population trajectories is important for informed management. However, the use of age ratio data (e.g., juveniles:adult females) as an index of variation in population dynamics is hindered by a lack of statistical power and difficult interpretation. Here, we show that the use of a population model based...

Data from: Designing data science workshops for data-intensive environmental science research

Allison Theobold, Stacey Hancock & Sara Mannheimer
Over the last 20 years, statistics preparation has become vital for a broad range of scientific fields, and statistics coursework has been readily incorporated into undergraduate and graduate programs. However, a gap remains between the computational skills taught in statistics service courses and those required for the use of statistics in scientific research. Ten years after the publication of "Computing in the Statistics Curriculum,'' the nature of statistics continues to change, and computing skills are...

Temporal and spatial limitations in global surveillance for bat filoviruses and henipaviruses

Daniel Becker, Daniel Crowley, Alex Washburne & Raina Plowright
Sampling reservoir hosts over time and space is critical to detect epizootics, predict spillover and design interventions. However, because sampling is logistically difficult and expensive, researchers rarely perform spatio-temporal sampling of many reservoir hosts. Bats are reservoirs of many virulent zoonotic pathogens such as filoviruses and henipaviruses, yet the highly mobile nature of these animals has limited optimal sampling of bat populations. To quantify the frequency of temporal sampling and to characterize the geographical scope...

Data From: A new perspective on transient characteristics of quiet stance postural control

Cody Reed, Ajit Chaudhari, Lise Worthen-Chaudhari, Kimberly Bigelow & Scott Monfort
Postural control provides insight into health concerns such as fall risk but remains relatively untapped as a vital sign of health. One understudied aspect of postural control involves transient responses within center of pressure (CoP) data to events such as vision occlusion. Such responses are masked by common whole-trial analyses. We hypothesized that the transient behavior of postural control would yield unique and clinically-relevant information for quiet stance compared to traditionally calculated whole-trial CoP estimates....

Analytic dataset informing prediction of subterranean cave and mine ambient temperatures

Meredith McClure, Daniel Crowley, Catherine Haase, Liam McGuire, Nathan Fuller, David Hayman, Cori Lausen, Raina Plowright, Brett Dickson & Sarah Olson
Caves and other subterranean features provide unique environments for many species. The importance of cave microclimate is particularly relevant at temperate latitudes where bats make seasonal use of caves for hibernation. White-nose syndrome (WNS), a fungal disease that has devastated populations of hibernating bats across eastern and central North America, has brought renewed interest in bat hibernation and hibernaculum conditions. A recent review synthesized current understanding of cave climatology, exploring the qualitative relationship between cave...

Response of lion demography and dynamics to the loss of preferred larger prey

Milan Vinks, Scott Creel, Paul Schuette, Matthew Becker, Elias Rosenblatt, Carolyn Sanguinetti, Kambwiri Banda, Ben Goodheart, Kim Young-Overton, Xia Stevens, Clive Chifunte, Neil Midlane & Chuma Simukonda
Large carnivores are experiencing range contraction and population declines globally. Prey depletion due to illegal offtake is considered a major contributor, but the effects of prey depletion on large carnivore demography are rarely tested. We measured African lion density and tested the factors that affect survival using mark-recapture models fit to six years of data from known individuals in Kafue National Park (KNP), Zambia. KNP is affected by prey depletion, particularly for large herbivores that...

Biotic and abiotic drivers of plant-pollinator community assembly across wildfire gradients

Joseph LaManna, Laura Burkle, R. Belote & Jonathan Myers
1. Understanding how abiotic disturbance and biotic interactions determine pollinator and flowering-plant diversity is critically important given global climate change and widespread pollinator declines. To predict responses of pollinators and flowering-plant communities to changes in wildfire disturbance, a mechanistic understanding of how these two trophic levels respond to wildfire severity is needed. 2. We compared site-to-site variation in community composition (β-diversity), species richness, and abundances of pollinators and flowering plants among landscapes with no recent...

Data from: Soil microbes alter herbivore-induced volatile emissions in response to cereal cropping systems

Shealyn Malone, Amy Trowbridge, David Weaver, Fabian Menalled, Tim Seipel & Megan Hofland
Soil microbes can influence the emissions of plant volatile organic compounds (VOCs), which serve as host-location cues for insect pests and their natural enemies. Agricultural practices steer unique soil microbial communities, but how this influences crop VOCs and subsequent insect attraction remains unknown. The aim of this study was to investigate the effect of diversified agricultural practices on constitutive and herbivore-induced VOC emissions by crops through soil-microbe legacy effects. In a full factorial experiment, we...

Uncovering patterns of freshwater positive interactions using meta‐analysis: identifying the roles of common participants, invasive species and environmental context

Michael MacDonald, Lindsey Albertson, Benjamin Tumolo, Michelle Briggs, Zachary Maguire, Sierra Quinn, Jose Sanchez-Ruiz, Jaris Veneros & Laura Burkle
General understanding of freshwater positive interactions has been far outpaced by knowledge of these important relationships in terrestrial and marine ecosystems. Positive interactions are sensitive to human impacts, necessitating synthetic approaches to elucidate broad patterns and predict future changes if these interactions are altered or lost. We conducted a global meta-analysis to evaluate the magnitude of positive interactions across freshwater habitats. In 340 studies, we found substantial positive effects, with facilitators increasing beneficiaries by, on...

Individual variation creates diverse migratory portfolios in native populations of a mountain ungulate

Blake Lowrey, Doug McWhirter, Kelly Proffitt, Kevin Monteith, Alyson Courtemanch, Patrick White, John Paterson, Sarah Dewey & Robert Garrott
Ecological theory and empirical studies have demonstrated population‐level demographic benefits resulting from a diversity of migratory behaviors with important implications for ecology, conservation, and evolution of migratory organisms. Nevertheless, evaluation of migratory portfolios (i.e., the variation in migratory behaviors across space and time among individuals within populations) has received relatively little attention in migratory ungulates, where research has focused largely on the dichotomous behaviors (e.g., resident and migrant) of partially migratory populations. Using GPS data...

Repeated fire shifts carbon and nitrogen cycling by changing plant inputs and soil decomposition across ecosystems

Adam Francis Pellegrini, Sarah Hobbie, Peter Reich, Ari Jumpponen, Jack Brookshire, Anthony Caprio, Corli Coetsee & Robert Jackson
Fires shape the biogeochemistry and functioning of many ecosystems, and fire frequencies are changing across much of the globe. Frequent fires can change soil carbon (C) and nitrogen (N) storage by altering the quantity and chemistry of plant inputs through changes in plant biomass and composition as well as altering decomposition of soil organic matter. How decomposition rates change with shifting inputs remains uncertain because most studies focus on the effects of single fires, where...

Data from: Assessing cetacean populations using integrated population models: an example with Cook Inlet beluga whales

Eiren Jacobson, Charlotte Boyd, Tamara McGuire, Kim Shelden, Gina Himes Boor & André Punt
Effective conservation and management of animal populations requires knowledge of abundance and trends. For many species, these quantities are estimated using systematic visual surveys. Additional individual-level data are available for some species. Integrated population modelling (IPM) offers a mechanism for leveraging these datasets into a single estimation framework. IPMs that incorporate both population- and individual-level data have previously been developed for birds, but have rarely been applied to cetaceans. Here, we explore how IPMs can...

Matthew T. Regan, Scott W. H. Young & Sara Mannheimer
Objective: Reflective assessment is an effective method of teacher evaluation, serving as an approach for, assessing teaching practices, generating insights, and connecting with colleagues, ultimately supporting meaningful transformation of teaching practice. In this paper, three librarians model a reflective assessment approach in evaluating and improving their experiences implementing learner-driven teaching practices in credit-bearing courses in topics related to library and information studies. Methods: Following a model of reflective assessment, we ask ourselves how our practice...

Data from: Translocation with targeted vaccination is the most effective strategy to protect an island endemic bird threatened by West Nile virus

Victoria Bakker, T. Sillett, Walter Boyce, Daniel Doak, T. Winston Vickers, William Reisen, Brian Cohen, Michael Hallworth & Scott Morrison
Aim Invasive pathogens are a growing conservation challenge and often occur in tandem with rapid environmental transformation, such as climate change, drought, and habitat loss. Climate change appears to have facilitated the spread of West Nile virus (WNV), a cause of widespread avian mortality. WNV is considered the primary threat to island scrub-jays (Aphelocoma insularis), endemic to Santa Cruz Island, California. Two approaches have been proposed to safeguard island scrub-jays: (1) vaccination and (2) conservation...

Body mass and hibernation microclimate may predict bat susceptibility to white-nose syndrome

Catherine Haase, Nathan Fuller, Yvonne Dzal, C. Reed Hranac, David Hayman, Cori Lausen, Kirk Silas, Sarah Olson & Raina Plowright
In multi-host disease systems, differences in mortality between species may reflect variation in host physiology, morphology, and behavior. In systems where the pathogen can persist in the environment, microclimate conditions, and the adaptation of the host to these conditions, may also impact mortality. White-nose syndrome is an emerging disease of hibernating bats caused by an environmentally persistent fungus, Pseudogymnoascus destructans. We assessed the effects of body mass, torpid metabolic rate, evaporative water loss, and hibernaculum...

Montana surveys of codling moth damage to apple fruit 2019-2020

Rachel Leisso, Chase Anderson, Tracy Novak, Katrina Mendrey, Olivia Soller & Zach Miller
Codling moth (Cydia pomonella) is the major insect pest of pome fruit (apples and pears) in Montana. This dataset reports codling moth damage to apple fruit ("strikes") in Montana orchards where site managers were not applying pesticides to control codling moth. Data was collected in August or September of 2019 and 2020. Certain sites east of the continental divide have nominally lower incidence of codling moth damage to fruit than sites west of the divide....

Communicating risk in human-wildlife interactions: how stories and images move minds

Sara Guenther & Elizabeth Shanahan
Effectively communicating risk is critical to reducing conflict in human-wildlife interactions. Using a survey experiment fielded in the midst of contentious public debate over flying fox management in urban and suburban areas of Australia, we find that stories with characters (i.e., narratives) are more effective than descriptive information at mobilizing support for different forms of bat management, including legal protection, relocation, and habitat restoration. We use conditional process analysis to show that narratives, particularly with...

Habitat Selection by a Threatened Desert Amphibian

Ross Hinderer
Aim. Habitat degradation and fragmentation are major drivers of amphibian declines. The loss of environmental features that allow for movement between water sources may be particularly detrimental for amphibians in arid environments. Climate changes will increase the importance of microhabitats to amphibians. Enhancing areas to facilitate movement may be a necessary conservation strategy for many animal species that depend on wetlands, including federally-threatened Chiricahua leopard frogs (Lithobates chiricahuensis). Habitat preferences of this frog species are...

Disentangling interactions among mercury, immunity, and infection in a Neotropical bat community

Daniel Becker, Kelly Speer, Jennifer Korstian, Dmitriy Volokhov, Hannah Droke, Alexis Brown, Catherene Baijnauth, Ticha Padgett-Stewart, Hugh Broders, Raina Plowright, Thomas Rainwater, Brock Fenton, Nancy Simmons & Matthew Chumchal
Contaminants such as mercury are pervasive and can have immunosuppressive effects on wildlife. Impaired immunity could be important for forecasting pathogen spillover risks, as many land-use changes that generate mercury contamination also bring wildlife into close contact with humans and domestic animals. However, the interactions among contaminants, immunity, and infection are difficult to study in natural systems, and empirical tests of possible directional relationships remain rare. We capitalized on extreme mercury variation in a diverse...

Ecological and evolutionary drivers of hemoplasma infection and genotype sharing in a Neotropical bat community

Daniel Becker, Kelly Speer, Alexis Brown, Alex Washburne, Brock Fenton, Sonia Altizer, Daniel Streicker, Raina Plowright, Vladimir Chizhikov, Nancy Simmons & Dmitriy Volokhov
Most emerging pathogens can infect multiple species, underscoring the importance of understanding the ecological and evolutionary factors that allow some hosts to harbor greater infection prevalence and share pathogens with other species. However, our understanding of pathogen jumps is primarily based around viruses, despite bacteria accounting for the greatest proportion of zoonoses. Because bacterial pathogens in bats (Order: Chiroptera) can have conservation and human health consequences, studies that examine the ecological and evolutionary drivers of...
