Risky business: how an herbivore navigates spatio-temporal aspects of risk from competitors and predators

Katey Huggler, Joseph Holbrook, Matthew Hayes, Patrick Burke, Mark Zornes, Daniel Thompson, Justin Clapp, Patrick Lionberger, Miguel Valdez & Kevin Monteith
Understanding factors that influence animal behavior is central to ecology. Basic principles of animal ecology imply that individuals should seek to maximize survival and reproduction, which means carefully weighing risk against reward. Decisions become increasingly complex and constrained, however, when risk is spatiotemporally variable. We advance a growing body of work in predator-prey behavior by evaluating novel questions where a prey species is confronted with multiple predators and a potential competitor. We tested how fine-scale...

Heterogeneity in risk-sensitive allocation of somatic reserves in a long-lived mammal

Rachel Smiley, Rachel Smiley, Brittany L. Wagler, Tayler LaSharr, Kristin Denryter, Thomas Stephenson, Alyson Courtemanch, Tony Mong, Daryl Lutz, Doug McWhirter, Doug Brimeyer, Patrick Hnilicka, Blake Lowrey & Kevin Monteith
Patterns of food quality and availability, when combined with energetic demands in seasonal environments, shape resource acquisition and allocation by animals and hold consequences for life-history strategies. In long-lived species with extensive maternal care, regulation of somatic reserves of energy and protein can occur in a risk-sensitive manner, wherein resources are preferentially allocated to support survival at the cost of investment in reproduction. We investigated how Rocky Mountain bighorn sheep (Ovis canadensis), an alpine mammal...

10Be concentrations constraining surface age and valley growth rate in a seepage-derived drainage network in the Apalachicola River basin, Florida

Emma Harrison, Brandon McElroy & Jane Willenbring
Measuring rates of valley head migration and determining the timing of canyon-opening are insightful quantifications for the history and evolution of planetary surfaces. Horizontal spatial gradients of in situ-produced cosmogenic nuclide concentrations provide a framework for assessing the migration of these and similar topographic features. We developed a theoretical model for the concentration of in situ produced cosmogenic radionuclides in valley walls during retreat of a valley head. The retreat rate is inversely proportional to...

A polygenic architecture with habitat-dependent effects underlies ecological differentiation in Silene

Susanne Gramlich, Xiaodong Liu, C. Alex Buerkle, Adrien Favre & Sophie Karrenberg
Ecological differentiation can drive speciation but it is unclear how the genetic architecture of habitat-dependent fitness contributes to lineage divergence. We investigated the genetic architecture of cumulative flowering, a fitness component, in second-generation hybrids between Silene dioica and S. latifolia transplanted into the natural habitat of each species. We used reduced-representation sequencing and Bayesian Sparse Linear Mixed Models (BSLMMs) to analyze the genetic control of cumulative flowering in each habitat. Our results point to a...

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...

Cats and dogs: A mesopredator navigating risk and reward provisioned by an apex predator

Mitchell J. Brunet, Kevin Monteith, Katey Huggler, Justin Clapp, Daniel Thompson, Patrick Burke, Mark Zornes, Patrick Lionberger, Miguel Valdez & Joseph Holbrook
Successfully perceiving risk and reward is fundamental to the fitness of an animal, and can be achieved through a variety of perception tactics. For example, mesopredators may ‘directly’ perceive risk by visually observing apex predators, or may ‘indirectly’ perceive risk by observing habitats used by predators. Direct assessments should more accurately characterize the arrangement of risk and reward; however, indirect assessments are used more frequently in studies concerning the response of GPS-marked animals to spatiotemporally...

Predicting potential distributions of large carnivores in Kenya: An occupancy study to guide conservation

Femke Broekhuis, Shadrack Ngene, Arjun Gopalaswamy, Anastacia Mwaura, Stephanie Dloniak, Dedan Ngatia, Peter Tyrrell, Yumi Yamane & Nicholas Elliot
Aim: Species distribution maps are frequently the foundation upon which species-specific conservation strategies are developed, however, mapping species distribution is challenging, especially across large spatial extents. Our aim was to use a novel empirical approach to predict the national distribution for all six large carnivore species found in Kenya to guide conservation and management decisions by identifying knowledge and conservation gaps. Location: Kenya Methods: Data on carnivore presence and absence were collected through questionnaires and...

The role of multiple Pleistocene refugia in promoting diversification in the Pacific Northwest

Megan Smith, Jessica Wallace, David Tank, Jack Sullivan & Bryan Carstens
Pleistocene glacial cycles drastically changed the distributions of taxa endemic to temperate rainforests in the Pacific Northwest, with many experiencing reduced habitat suitability during glacial periods. In this study, we investigate whether glacial cycles promoted intraspecific divergence and whether subsequent range changes led to secondary contact and gene flow. For seven invertebrate species endemic to the PNW, we estimated Species Distribution Models (SDMs) and projected them onto current and historical climate conditions to assess how...

Estimates of circadian period for family lines of Boechera stricta

Robby McMinn
Circadian clocks confer adaptation to predictable 24-h fluctuations in the exogenous environment, but it has yet to be determined what ecological factors maintain natural genetic variation in endogenous circadian period outside of the hypothesized optimum of 24 h. We estimated quantitative genetic variation in circadian period in leaf movement in 30 natural populations of the Arabidopsis relative Boechera stricta sampled within only 1° of latitude but across an elevation gradient spanning 2460−3300 m in the...

Wildfire influences individual growth and breeding dispersal, but not survival and recruitment in a montane amphibian

Gabriel Barrile, Anna Chalfoun, Wendy Estes-Zumpf & Annika Walters
Global wildfire regimes are changing rapidly, with widespread increases in the size, frequency, duration, and severity of wildfires. Whereas the effects of wildfire on ecological state variables such as occupancy, abundance, and species diversity are relatively well-documented, changes in population vital rates (e.g., survival, recruitment) and individual responses (e.g., growth, movement) to wildfire are more limited because of the detailed information needed on the same individuals both pre- and post-fire. We capitalized on the 2018...

Data from: Defensible-space treatment of 114,000 ha within 40 m of high-risk buildings could reduce WUI wildfire disaster risk to low levels across Colorado's 27 million ha

William Baker
Context WUI wildfire disasters are increasing, as fires are pushed by strong winds and drier fuels across landscapes and into communities. Possible disasters make maintaining and restoring landscape-scale fire in fire-adapted ecosystems difficult. Rapid action is needed to reduce wildfire disasters. Objectives In a Colorado case study, I used new distance-based empirical modeling to refine the risk of WUI wildfire disasters to focus the task of reducing them. Methods New empirical modeling results showed 95%...

Ecological outcomes of hybridization vary extensively in Catostomus fishes

Elizabeth Mandeville, Elizabeth Mandeville, Robert Ogden Hall & Alex Buerkle
Hybridization outcomes vary geographically and can depend on the environment. Hybridization can also reshape biotic interactions, leading to ecological shifts. If hybrids function differently ecologically in ways that enhance or reduce fitness, and those ecological roles vary geographically, ecological factors might explain variation in hybridization outcomes. However, relatively few studies have focused on ecological traits of hybrids. We compared the feeding ecology of Catostomus fish species and hybrids by using stable isotopes δ13C and δ15N...

Data From: Getting cited early: influence of visibility strategies, structure, and focal system on early citation rates

Emily R. Gelzer, Michel P. Laforge, Justine A. Becker, Nathaniel P. Hough, Mallory Sandoval Lambert, Marie-Pier Poulin, Rebecca Thomas-Kuzilik, Tana L. Verzuh & Jerod A. Merkle
Elucidating factors that contribute to citation rates of scientific articles can help scientists write manuscripts that have a stronger influence on their scientific field and wildlife management, and are accessible to a broad audience. Using a cohort of 778 articles published in The Journal of Wildlife Management from 2011–2015, we examined how visibility strategies (e.g., open access, increasing the Atlmetric Attention Score, self-citations), article structure, and focal system – all factors authors can predominantly control...

Links between personality traits and problem-solving performance in zebra finches (Taeniopygia guttata)

Lisa P. Barrett, Jessica L. Marsh, Neeltje Boogert, Christopher N. Templeton & Sarah Benson-Amram
Consistent individual differences in behaviour across time or contexts (i.e., personality types) have been found in many species and have implications for fitness. Likewise, individual variation in cognitive abilities has been shown to impact fitness. Cognition and personality are complex, multidimensional traits. However, previous work has generally examined the connection between a single personality trait and a single cognitive ability, yielding equivocal results. Links between personality and cognitive ability suggest that behavioural traits coevolved and...

Environmentally associated variation in dispersal distance affects inbreeding risk in a stream salamander

Brett Addis & Winsor Lowe
Avoiding inbreeding is considered a key driver of dispersal evolution, and dispersal distances should be especially important in mediating inbreeding risk because the likelihood of mating with relatives decreases with dispersal distance. However, a lack of direct data on dispersal distances has limited empirical tests of this prediction, particularly in the context of the multiple selective forces that can influence dispersal. Using a headwater salamander system, we tested whether spatial variation in environmental conditions leads...

Climatic drivers and ecological impacts of a rapid range expansion by non-native smallmouth bass

Mark Kirk
Smallmouth bass (Micropterus dolomieu) are a globally introduced fish species that have experienced widespread range expansions in recent decades and which can have deleterious effects on native fish communities. Rapidly assessing their expansions will aid conservation and management actions geared towards controlling their spread and mitigating their impacts. Smallmouth bass have recently experienced a rapid upstream expansion in a Great Plains river (Laramie River, Wyoming, USA), which provided an opportunity to evaluate the drivers and...

Phylogenomic analyses in Phrymaceae reveal extensive gene tree discordance in relationships among major clades

Diego F. Morales-Briones, Nan Lin, Eileen Huang, Dena Grossenbacher, James Sobel, Caroline Gilmore, David Tank & Ya Yang
• Premise of the study: Phylogenomic datasets using genomes and transcriptomes provide rich opportunities beyond resolving bifurcating phylogenetic relationships. Monkeyflower (Phrymaceae) is a model system for evolutionary ecology. However, it lacks a well-supported phylogeny for a stable taxonomy and for macroevolutionary comparisons. • Methods: We sampled 24 genomes and transcriptomes in Phrymaceae and closely related families, including eight newly sequenced transcriptomes. We reconstructed the phylogeny using IQ-TREE and ASTRAL, evaluated gene tree discordance using PhyParts,...

Responses to natural gas development differ by season for two migratory ungulates

Mallory Sandoval Lambert, Hall Sawyer & Jerod Merkle
While migrating, animals make directionally persistent movements and may only respond to human-induced rapid environmental change (HIREC), such as climate and land-use change, once a threshold of HIREC is surpassed. In contrast, animals on other seasonal ranges (e.g., winter range) make more localized and tortuous movements while foraging and may have the flexibility to adjust the location of their range and the intensity of use within it to minimize interactions with HIREC. Because of these...
