Water availability dictates how plant traits predict demographic rates

Alice Stears, Peter Adler, Dana Blumenthal, Julie Kray, Kevin Mueller, Troy Ocheltree, Kevin Wilcox & Daniel Laughlin
A major goal in ecology is to make generalizable predictions of organism responses to environmental variation based on their traits. However, straightforward relationships between traits and fitness are rare and likely vary with environmental context. Characterizing how traits mediate demographic responses to the environment may enhance predictions of organism responses to global change. We synthesized 15 years of demographic data and species-level traits in a shortgrass steppe to determine whether the effects of leaf and...

Teamwork Makes the Dream Work: Collaboratively Navigating Information Literacy Instruction in the Classroom

Niki Fullmer & Katie Strand
Teaching students to critically think and effectively research and write is a tall task, but an important one in ensuring students become informed citizens. The good news is we don’t have to face these challenging concepts alone. In Spring 2022, USU Librarians conducted a research study to better understand information literacy instruction that is occurring in our local high schools as well as understand teacher/librarian collaborations. Presenters will share key findings from this study and...

Modeling management strategies for chronic disease in wildlife: predictions for the control of respiratory disease in bighorn sheep

Kezia Manlove, Emily Almberg, E. Frances Cassirer, Jennifer Ramsey, Keri Carson, Justin Gude & Raina Plowright
1. Controlling persistent infectious disease in wildlife populations is an on-going challenge for wildlife managers and conservationists worldwide. 2. Here, we develop a dynamic pathogen transmission model capturing key features of M. ovipneumoniae infection, a major cause of population declines in North American bighorn sheep (Ovis canadensis). We explore the effects of model assumptions and parameter values on disease dynamics, including density versus frequency dependent transmission, the inclusion of a carrier class versus a longer...

Tipping the balance: the role of seed density, abiotic filters, and priority effects in seed-based wetland restoration

Emily Tarsa, Bailey Holdaway & Karin Kettenring
Sowing native seeds is a common approach to reintroduce native plants to degraded systems. However, this method is often overlooked in wetland restoration despite the immense global loss of diverse native wetland vegetation. Developing guiding principles for seed-based wetland restoration is critical to maximize native plant recovery, particularly in previously invaded wetlands. Doing so requires a comprehensive understanding of how restoration manipulations, and their interactions, influence wetland plant community assembly. With a focus on the...

Chemical defense strategies, induction timing, growth, and tradeoffs in Pinus aristata and Pinus flexilis

David Soderberg
Tradeoffs among plant defense investment and fitness traits, including growth, are often invoked to explain evolutionary strategies targeted at resisting herbivores. Many Pinus species have specialized herbivores, including the mountain pine beetle, Dendroctonus ponderosae, (MPB), and have historically been a focus of defense investigations. We compared defense traits of two high-elevation Pinus species, P. aristata and P. flexilis, that are hosts to MPB and hypothesized to have different growth and defense traits and potential tradeoffs....

Data from: Population genomic evidence of selection on structural variants in a natural hybrid zone

Zachariah Gompert, Linyi Zhang, Samridhi Chaturvedi, Chris Nice & Lauren Lucas
Structural variants (SVs) can promote speciation by directly causing reproductive isolation or by suppressing recombination across large genomic regions. Whereas examples of each mechanism have been documented, systematic tests of the role of SVs in speciation are lacking. Here, we take advantage of long-read (Oxford nanopore) whole-genome sequencing and a hybrid zone between two Lycaeides butterfly taxa (L. melissa and Jackson Hole Lycaeides) to comprehensively evaluate genome-wide patterns of introgression for SVs and relate these...

American Beaver: GPS and VHF tag data from resident and translocated beavers on the Price and San Rafael Rivers, Utah

Julie Young, Emma Doden, Tal Avgar & Phaedra Budy
Wildlife translocations can dramatically alter animal movement behavior. Thus, identifying common movement patterns post-translocation can aid in setting expectations and anticipating animal behavior in subsequent efforts. American and Eurasian beavers (Castor canadensis; C. fiber) are frequently translocated for reintroduction efforts, to mitigate human-wildlife conflict, and for use as an ecosystem restoration tool. However, little is known about movement behavior of translocated beavers post-release, especially in desert rivers where resources are patchy and dynamic. We identified...

Scale-dependent species-area relationship: niche-based versus stochastic processes in a typical subtropical forest

Haibao Ren, Jens-Christian Svenning, Xiangcheng Mi, James A. Lutz, Jinxing Zhou & Keping Ma
Determining the patterns and drivers of the small-scale species-area relationship (SAR) is crucial for improving our understanding of community assembly and biodiversity patterns. Niche-based and stochastic processes are two principal categories of mechanisms potentially driving SARs. However, their relative importance has rarely been quantified rigorously owing to scale-dependence and the simplified niche volumes often used. In a fully mapped, 24-ha plot of a typical subtropical forest, we built the SARs and well-defined niche-hyper-volumes of a...

ddRAD data for: Multiple introductions and overwintering shape the progressive invasion of Aedes albopictus beyond the Alps

Laura Vavassori, Ann-Christin Honnen, Norah Saarman, Adalgisa Caccone & Pie Müller
Aedes albopictus originates from Southeast Asia and is considered one of the most invasive species globally. This mosquito is a nuisance and a disease vector of significant public health relevance. In Europe, Ae. albopictus is firmly established and widespread south of the Alps, a mountain range that forms a formidable biogeographic barrier to many organisms. Recent reports of Ae. albopictus north of the Alps raise questions of 1) the origins of its recent invasion, and...

Data from: Bighorn sheep show similar in-host responses to the same pathogen strain in two contrasting environments

Kezia Manlove, Annette Roug, Kent Hersey, Cameron Martinez, Michael Martinez, Kerry Mower, Talisa Ortega, Eric Rominger, Caitlin Ruhl, Nicole Tatman & Jace Taylor
Ecological context – the biotic and abiotic environment, along with its influence on population mixing dynamics and individual susceptibility – are thought to have major bearing on epidemic outcomes. However, direct comparisons of disease events in contrasting ecological contexts in wildlife systems are often confounded by concurrent differences in host genetics, exposure histories, or pathogen strains. Here, we compare disease dynamics of a Mycoplasma ovipneumoniae spillover event that affected bighorn sheep populations in two contrasting...
