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...

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 40 m from high-risk buildings near wildland vegetation could reduce loss in WUI wildfire disasters 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 building loss in WUI wildfire disasters. Objectives In a Colorado case study, I used distance-based empirical modeling to refine potential risk of building loss in WUI wildfire disasters to focus risk-reduction efforts. Methods New empirical modeling...

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...

An insect-pollinated species in a wind-pollinated genus: case study of the endemic plant, Laramie chickensage (Artemisia simplex)

Madison S Crawford & Lusha Tronstad
Artemisia simplex (Laramie chickensage) is an imperiled, endemic plant in southeastern Wyoming, USA. To fill critical information gaps, we measured its seed viability and pollination mechanisms, measures that are lacking for many rare and endemic plants yet critical for the perpetuation of species. Artemisia simplex cover varied among sites and occupied 5.5% (range: 1.3–14.6%) of the area on average. This unique plant typically produced viable seeds under ambient conditions but did not self-pollinate. Characteristics of...

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...

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...

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...

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...

Genomics‐informed delineation of conservation units in a desert amphibian

Brenna Forester, Melanie Murphy, Chad Mellison, Jeffrey Petersen, David Pilliod, Rachel Van Horne, Jim Harvey & W. Chris Funk
Delineating conservation units (CUs, e.g., evolutionarily significant units, ESUs, and management units, MUs) is critical to the recovery of declining species because CUs inform both listing status and management actions. Genomic data have strengths and limitations in informing CU delineation and related management questions in natural systems. We illustrate the value of using genomic data in combination with landscape, dispersal, and occupancy data, to inform CU delineation in Nevada populations of the Great Basin Distinct...

Climate disequilibrium of fishes along elevation and latitudinal gradients: implications for climate tracking

Mark Kirk
Aim: Differences in realized and fundamental thermal niches can reveal how temperature constrains species distributions. Because climate-induced range shifts assume that temperature influences distribution limits (i.e., climate equilibrium assumption), understanding the factors that determine the realized thermal niche of species is critical for understanding their climate tracking abilities. Location: Thermal niches were evaluated for two scales: Globally (n = 95 species) and across the Great Plains – Rocky Mountain region, U.S.A (n = 28 species)...

Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna

Harry Wells, Ramiro Crego, Jesse Alston, S. Kimani Ndung'u, Leo Khasoha, Courtney Reed, Abdikadir Hassan, Samson Kurukura, Jackson Ekadeli, Mathew Namoni, Peter Stewart, Duncan Kimuyu, Amelia Wolf, Truman Young, Tyler Kartzinel, Todd Palmer, Jacob Goheen & Robert Pringle
1. Whether wild herbivores confer biotic resistance to invasion by exotic plants remains a key question in ecology. There is evidence that wild herbivores can impede invasion by exotic plants, but it is unclear whether and how this generalises across ecosystems with varying wild herbivore diversity and functional groups of plants, particularly over long-term (decadal) time frames. 2. Using data from three long-term (13- to 26-year) exclosure experiments in central Kenya, we tested the effects...

Nutritional condition and net body weight for adult female mule deer (Nov 2017–Mar 2018), Wyoming, USA

Anna Ortega, Tayler LaSharr, Matthew Kauffman & Kevin Monteith
Many temperate and polar animals have developed physiological and behavioral adaptations to survive the challenging conditions of winter. Some animals hibernate to reduce energetic expenditure while other animals, including ungulates, migrate to avoid cold temperatures and deep snow. Despite moving vast distances between seasonal ranges, many migratory ungulates are unable to escape the energetic challenges of winter and often rely on reserves of fat to withstand food scarcity and a negative energy balance. The mobilization...

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...

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...

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...

Body size and digestive system shape resource selection by ungulates: a cross-taxa test of the Forage Maturation Hypothesis

Saeideh Esmaeili, Brett Jesmer, Shannon Albeke, Ellen Aikens, Kathryn Schoenecker, Sarah King, Briana Abrahms, Bayarbaatar Buuveibaatar, Jeffrey Beck, Randall Boone, Francesca Cagnacci, Simon Chamaillé-Jammes, Buyanaa Chimeddorj, Paul Cross, Nandintsetseg Dejid, Jagdag Enkhbayar, Ilya Fischhoff, Adam Ford, Kate Jenks, Mahmoud-Reza Hemami, Jacob Hennig, Takehiko Ito, Petra Kaczensky, Matthew Kauffman, John Linnell … & Jacob Goheen
The Forage Maturation Hypothesis (FMH) states that energy intake for ungulates is maximized when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource selection should vary across ungulate species. By combining GPS relocations with remotely-sensed data on forage characteristics and surface water, we quantified the effect of body size and digestive system in determining movements of 30 populations of hindgut fermenters (equids) and ruminants across biomes. Selection for...

The gut microbiome reflects ancestry despite dietary shifts across a hybrid zone

Danny Nielsen, Joshua Harrison, Nathan Byer, Trevor Faske, Thomas Parchman, W. Brian Simison & Marjorie Matocq
The microbiome is critical to an organism’s phenotype, and its composition is shaped by, and a driver of, eco-evolutionary interactions. We investigated how host ancestry, habitat, and diet shape gut microbial composition in a mammalian hybrid zone that occurs across an ecotone between distinct vegetation communities. We found that habitat is the primary determinant of diet, while host genotype is the primary determinant of the gut microbiome—a finding further supported by intermediate microbiome composition in...

Data from: Maternal effects and the legacy of extreme environmental events for wild mammals

Tayler LaSharr
Nutrition underpins population dynamics of large herbivores. The environmental, physiological, and nutritional state of a mother can have a lifetime effect on her offspring. For ungulates, nutrition of the mother during gestation can have an important and often underappreciated effect on the lifetime phenotype, behavior, and success of her offspring. Research in captive settings has shown even with animals that are closely related (i.e., have similar genetic makeups), maternal condition can have serious lifetime implications...

Data from: Rocky Mountain forests are poised to recover following bark beetle outbreaks, but with altered composition

Kyle Rodman, Robert Andrus, Amanda Carlson, Trevor Carter, Teresa Chapman, Jonathan Coop, Paula Fornwalt, Nathan Gill, Brian Harvey, Ashley Hoffman, Katharine Kelsey, Dominik Kulakowski, Daniel Laughlin, Jenna Morris, José Negrón, Katherine Nigro, Gregory Pappas, Miranda Redmond, Charles Rhoades, Monique Rocca, Zoe Schapira, Jason Sibold, Camille Stevens-Rumann, Thomas Veblen, Jianmin Wang … & Sarah Hart
Amplified by warming temperatures and drought, recent outbreaks of native bark beetles (Curculionidae: Scolytinae) have caused extensive tree mortality throughout Europe and North America. Despite their ubiquitous nature and important effects on ecosystems, forest recovery following such disturbances is poorly understood, particularly across regions with varying abiotic conditions and outbreak effects. To better understand post-outbreak recovery across a topographically complex region, we synthesized data from 16 field studies spanning subalpine forests in the Southern Rocky...

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...

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...

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...
