Data from: The importance of functional responses among competing predators for avian nesting success

Kristen Ellis, Randy Larsen & Dave Koons
1. The relationship between the rate of predation and prey abundance is an important component of predator-prey dynamics. However, functional responses are less straightforward when multiple predators compete for shared prey. Interactions among competing predators can reduce or enhance effects of predation on prey populations. Because many avian populations experience high rates of nest predation, understanding the role of specific predators on nest mortality will lead to more informed conservation and management strategies which attempt...

Mass ratio effects underlie ecosystem responses to environmental change

Melinda Smith, Sarah Koerner, Alan K. Knapp, Meghan Avolio, Francis Chaves, Elsie Denton, John Dietrich, David Gibson, Jesse Gray, Ava Hoffman, David Hoover, Kimberly La Pierre, Andrea Silletti, Kevin Wilcox, Qiang Yu & John Blair
1. Random species loss has been shown experimentally to reduce ecosystem function, sometimes more than other anthropogenic environmental changes. Yet, controversy surrounds the importance of this finding for natural systems where species loss is non-random. 2. We compiled data from 16 multi-year experiments located at a single site in native tallgrass prairie. These experiments included responses to 11 anthropogenic environmental changes, as well as non-random biodiversity loss - either the removal of uncommon/rare plant species...

Data from: Modeling multi-species and multi-mode contact networks: implications for persistence of bovine tuberculosis at the wildlife-livestock interface

Mark Q. Wilber, Kim M. Pepin, , Scott E. Hygnstrom, Michael J. Lavelle, Tatiana Xifara, Kurt C. Vercauteren & Coleen T. Webb
1. Individual- and species-level heterogeneity in contact rates can alter the ability of a pathogen to invade a host community. Many pathogens have multiple modes of transmission -- by direct or indirect contact. It is important to identify the role of heterogeneity in different types of transmission when managing the risk of disease spillover at the interface among different host species. 2. We developed a network-based analysis to explore how individual- and species-level heterogeneity shape...

Ensemble model output of North American atmospheric CO2 simulation (full WRF-chem output)

S. Feng, T. Lauvaux, K.J. Davis, K. Keller, R. Rayner, T. Oda, K. Gurney, Y. Zhou, C. Williams, A.E. Schuh, J. Liu & I. Baker
The uncertainty in biospheric carbon dioxide (CO2) flux estimates drives divergent projections of future climate and uncertainty in prescriptions for climate mitigation. The terrestrial carbon sink can be inferred from atmospheric CO2 observations with transport models via inversion methods. Regional CO2 flux estimates remain uncertain due to the mixture of uncertainties caused by transport models, prior estimates of biospheric fluxes, large-scale CO2 boundary inflow, the assumptions in the inversion process, and the limited density of...

Data from: Community-based wildlife management area supports similar mammal species richness and densities compared to a national park

Christian Kiffner, Seth Thomas, Talia Speaker, Victoria O’Connor, Paige Schwarz, John Kioko & Bernard Kissui
Community-based conservation models have been widely implemented across Africa to improve wildlife conservation and livelihoods of rural communities. In Tanzania, communities can set aside land and formally register it as Wildlife Management Area (WMA), which allows them to generate revenue via consumptive or non-consumptive utilization of wildlife. The key, yet often untested, assumption of this model is that economic benefits accrued from wildlife motivate sustainable management of wildlife. To test the ecological effectiveness (here defined...

Data from: Prolonged exposure to manure from livestock administered antibiotics decreases ecosystem carbon-use efficiency and alters nitrogen cycling

Carl Wepking, Brian Badgley, Jeb Barrett, Katharine Knowlton, Jane Lucas, Kevan Minick, Partha Ray, Sarah Shawver & Michael Strickland
Microbial communities drive soil ecosystem function but are also susceptible to environmental disturbances. We investigated whether exposure to manure sourced from cattle either administered or not administered antibiotics affected microbially-mediated terrestrial ecosystem function. We quantified changes in microbial community composition via amplicon sequencing, and terrestrial elemental cycling via a stable isotope pulse-chase. Exposure to manure from antibiotic-treated cattle caused: i) changes in microbial community structure; and ii) alterations in elemental cycling throughout the terrestrial system....

Data from: Vocal characteristics of prairie dog alarm calls across an urban noise gradient

Graeme Shannon, Megan F. McKenna, Grete Wilson-Henjum, Lisa M. Angeloni, Kevin R. Crooks & George Wittemyer
Increasing anthropogenic noise is having a global impact on wildlife, particularly due to the masking of crucial acoustical communication. However, there have been few studies examining the impacts of noise exposure on communication in free-ranging terrestrial mammals. We studied alarm calls of black-tailed prairie dogs (Cynomys ludovicianus) across an urban gradient to explore vocal adjustment relative to different levels of noise exposure. There was no change in the frequency 5%, peak frequency or duration of...

Vertebrate and invertebrate herbivory data

Melinda Smith & David Gibson
Data are from a factorial experiment designed to test the effects of small mammals and above- and below-ground invertebrates on plant species richness and composition in native tallgrass prairie (Gibson et al. 1990, https://doi.org/10.1007/BF00318268).

Urbanization impacts apex predator gene flow but not genetic diversity across an urban-rural divide

Daryl R Trumbo, Patricia E Salerno, Kenneth Logan, Mat Alldredge, Roderick B Gagne, Christopher P Kozakiewicz, Simona Kraberger, Nick Fountain-Jones, Meggan E Craft, Scott Carver, Holly B Ernest, Kevin Crooks, Sue VandeWoude & W. Chris Funk
Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near human developed areas, but urbanization may be detrimental to their movement ecology, population structure, and genetic diversity. To investigate potential effects of urbanization in population connectivity of pumas, we performed a landscape genomics study of 130 pumas on the...

Data from: Integrated modeling predicts shifts in waterbird population dynamics under climate change

Qing Zhao, G. Scott Boomer & J. Andrew Royle
Climate change has been identified as one of the most important drivers of wildlife population dynamics. The in-depth knowledge of the complex relationships between climate and population sizes through density dependent demographic processes is important for understanding and predicting population shifts under climate change, which requires integrated population models (IPMs) that unify the analyses of demography and abundance data. In this study we developed an IPM based on Gaussian approximation to dynamic N-mixture models for...

Data from: Intrinsic traits of woodland caribou Rangifer tarandus caribou calves depredated by black bears Ursus americanus and coyotes Canis latrans

Matthew A. Mumma, Guillaume Bastille-Rousseau, Steve E. Gullage, Colleen E. Soulliere, Shane P. Mahoney & Lisette P. Waits
Individuals in substandard physical condition are predicted to be more vulnerable to predation. Support for this prediction is inconsistent partly as a result of differences across systems in the life histories of predator and prey species. Our objective was to examine the physical condition of woodland caribou (Rangifer tarandus caribou) calves depredated by two predators with different life histories in Newfoundland, Canada. Black bears (Ursus americanus) are capable of chasing calves at high speeds over...

Larger genomes linked to slower development and loss of late-developing traits

Molly C. Womack, Marissa J. Metz & Kim L. Hoke
Genome size varies widely among organisms and is known to affect vertebrate development, morphology, and physiology. In amphibians, genome size is hypothesized to contribute to loss of late-forming structures, although this hypothesis has mainly been discussed in salamanders. Here we estimated genome size for 22 anuran species and combined this novel dataset with existing genome size data for an additional 234 anuran species to determine whether larger genome size is associated with loss of a...

Data from: Seasonal climate effects on the survival of a hibernating mammal

Caylee A. Falvo, David N. Koons & Lise M. Aubry
Global climate change and associated regional climate variability is impacting the phenology of many species, ultimately altering individual fitness and population dynamics. Yet, few studies have considered the effects of pertinent seasonal climate variability on phenology and fitness. Hibernators may be particularly susceptible to changes in seasonal climate since they have a relatively short active season in which to reproduce and gain enough mass to survive the following winter. To understand whether and how seasonal...

Data from: Extreme site fidelity as an optimal strategy in an unpredictable and homogeneous environment

Brian D. Gerber, Mevin B. Hooten, Christopher P. Peck, Mindy B. Rice, James H. Gammonley, Anthony D. Apa & Amy J. Davis
1. Animal site fidelity structures space-use, population demography, and ultimately gene flow. Understanding the adaptive selection for site fidelity patterns provides a mechanistic understanding to both spatial and population processes. This can be achieved by linking space-use with environmental variability (spatial and temporal) and demographic parameters. However, rarely is the environmental context that drives the selection for site fidelity behavior fully considered. 2. We use ecological theory to understand whether the spatial and temporal variability...

Data from: Anacapa Toolkit: an environmental DNA toolkit for processing multilocus metabarcode datasets

Emily E. Curd, Zack Gold, Gaurav S. Kandlikar, Jesse Gomer, Max Ogden, Taylor O'Connell, Lenore Pipes, Teia M. Schweizer, Laura Rabichow, Meixi Lin, Baochen Shi, Paul H. Barber, Nathan Kraft, Robert Wayne & Rachel S. Meyer
1. Environmental DNA (eDNA) metabarcoding is a promising method to monitor species and community diversity that is rapid, affordable, and non-invasive. Longstanding needs of the eDNA community are modular informatics tools, comprehensive and customizable reference databases, flexibility across high-throughput sequencing platforms, fast multilocus metabarcode processing, and accurate taxonomic assignment. As bioinformatics tools continue to improve, addressing each of these demands within a single bioinformatics toolkit is becoming a reality. 2. Here we present an open...

Data from: Genomic pedigree reconstruction identifies predictors of mating and reproductive success in an invasive vertebrate

Brenna A Levine, Marlis R Douglas, Amy A Yackel Adams, Bjorn Lardner, Robert N Reed, Julie A Savidge & Michael E Douglas
The persistence of an invasive species is influenced by its reproductive ecology, and a successful control program must operate on this premise. However, the reproductive ecology of invasive species may be enigmatic due to factors that also limit their management, such as cryptic coloration and behavior. We explored the mating and reproductive ecology of the invasive Brown Treesnake (BTS: Boiga irregularis) by reconstructing a multigenerational genomic pedigree based on 654 single nucleotide polymorphisms for a...

Data from: Feline immunodeficiency virus in puma: estimation of force of infection reveals insights into transmission

Jennifer Reynolds, Scott Carver, Mark Cunningham, Ken Logan, Winston Vickers, Kevin Crooks, Sue VandeWoude & Meggan Craft
Determining parameters that govern pathogen transmission (such as the force of infection, FOI), and pathogen impacts on morbidity and mortality, is exceptionally challenging for wildlife. Vital parameters can vary, for example across host populations, between sexes and within an individual's lifetime. Feline immunodeficiency virus (FIV) is a lentivirus affecting domestic and wild cat species, forming species-specific viral--host associations. FIV infection is common in populations of puma (Puma concolor), yet uncertainty remains over transmission parameters and...

Persistence of an endangered native duck, feral mallards, and multiple hybrid swarms across the main Hawaiian Islands

Caitlin Wells, Philip Lavretsky, Michael Sorenson, Jeffrey Peters, Jeffrey DaCosta, Stephen Turnbull, Kimberly Uyehara, Christopher Malachowski, Bruce Dugger, John Eadie & Andrew Engilis
Interspecific hybridization is recognized as an important process in the evolutionary dynamics of both speciation and the reversal of speciation. However, our understanding of the spatial and temporal patterns of hybridization that erode versus promote species boundaries is incomplete. The endangered, endemic koloa maoli (or Hawaiian duck, Anas wyvilliana) is thought to be threatened with genetic extinction through ongoing hybridization with an introduced congener, the feral mallard (A. platyrhynchos). We investigated spatial and temporal variation...

Pojected temperature rise for 2040, 2060, 2080 and 2100, considering NOAA's climate model

Hussam Mahmoud
The data provided is the projected temperature rise for 2040, 2060, 2080 and 2100, considering the climate model from the NOAA’s (National Oceanic Atmospheric Administration) Geophysical Fluid Dynamics Laboratory GFDL-CM3 under three Representative Concentration Pathway (RCP) scenarios, which are named for the approximate radiative forcing in year 2100: the lower forcing scenario RCP 2.6, a moderate scenario RCP 6.0 and the higher forcing scenario RCP 8.5

Data from: Aridity Drives Spatiotemporal Patterns of Masting Across the Latitudinal Range of a Dryland Conifer

Andreas Wion, Peter Weisberg, Ian Pearse & Miranda Redmond
Masting, or the synchronous and irregular production of seed crops, is controlled by environmental cues and resource budgets. Increasing temperatures and shifting precipitation regimes may alter the frequency and magnitude of masting, especially in species that experience chronic resource stress. Yet the effects of a changing climate on seed production are unlikely to be uniform across populations, particularly those that span broad abiotic gradients. In this study, we assessed the spatiotemporal patterns of masting across...

Data from: Modeling multilocus selection in an individual-based, spatially-explicit landscape genetics framework

Erin Landguth, Brenna R. Forester, Andrew J. Eckert, Andrew J. Shirk, Mitra Menon, Amy Whipple, Casey C. Day & Samuel A. Cushman
We implemented multilocus selection in a spatially-explicit, individual-based framework that enables multivariate environmental gradients to drive selection in many loci as a new module for the landscape genetics programs, CDPOP and CDMetaPOP. Our module simulates multilocus selection using a linear additive model, providing a flexible platform to evaluate a wide range of genotype-environment associations. Importantly, the module allows simulation of selection in any number of loci under the influence of any number of environmental variables....

Data from: SRUD: a simple non-destructive method for accurate quantification of plant diversity dynamics

Pengfei Zhang, George A. Kowalchuk, Merel B. Soons, Mariet M. Hefting, Chengjin Chu, Jennifer Firn, Cynthia S. Brown, Xianhui Zhou, Xiaolong Zhou, Zhi Guo, Zhigang Zhao, Guozhen Du & Yann Hautier
1. Predicting changes in plant diversity in response to human activities represents one of the major challenges facing ecologists and land managers striving for sustainable ecosystem management. Classical field studies have emphasized the importance of community primary productivity in regulating changes in plant species richness. However, experimental studies have yielded inconsistent empirical evidence, suggesting that primary productivity is not the sole determinant of plant diversity. Recent work has shown that more accurate predictions of changes...

Data from: Mismatches between breeding phenology and resource abundance of resident alpine ptarmigan negatively affect chick survival

Gregory T. Wann, Cameron L. Aldridge, Amy E. Seglund, Sara J. Oyler-McCance, Boris C. Kondratieff & Clait E. Braun
1. Phenological mismatches – defined here as the difference in reproductive timing of an individual relative to the availability of its food resources – occur in many avian species. Mistiming breeding activities in environments with constrained breeding windows may have severe fitness costs due to reduced opportunities for repeated breeding attempts. Therefore, species occurring in alpine environments may be particularly vulnerable. 2. We studied fitness consequences of timing of breeding in an alpine-endemic species, the...

Data from: Climate outweighs native vs. non-native range-effects for genetics and common garden performance of a cosmopolitan weed

Christoph Rosche, Isabell Hensen, Adrian Schaar, Uzma Zehra, Marie Jasieniuk, Ragan M. Callaway, Damase P. Khasa, Mohammad M. Al-Gharaibeh, Ylva Lekberg, David U. Nagy, Robert W. Pal, Miki Okada, Karin Schrieber, Kathryn G. Turner, Susanne Lachmuth, Andrey Erst, Tomonori Tsunoda, Min Sheng, Robin Schmidt, Yanling Peng, Wenbo Luo, Yun Jäschke, Zafar A. Reshi & Manzoor A. Shah
Comparing genetic diversity, genetic differentiation and performance between native and non-native populations has advanced our knowledge of contemporary evolution and its ecological consequences. However, such between-range comparisons can be complicated by high among-population variation within native and non-native ranges. For example, native vs. non-native comparisons between small and non-representative subsets of populations for species with very large distributions have the potential to mislead because they may not sufficiently account for within-range adaptation to climatic conditions,...

Data from: A hierarchical Bayesian approach for handling missing classification data

Alison C. Ketz, Therese L. Johnson, Mevin B. Hooten & M. Thompson Hobbs
Ecologists use classifications of individuals in categories to understand composition of populations and communities. These categories might be defined by demographics, functional traits, or species. Assignment of categories is often imperfect, but frequently treated as observations without error. When individuals are observed but not classified, these “partial” observations must be modified to include the missing data mechanism to avoid spurious inference. We developed two hierarchical Bayesian models to overcome the assumption of perfect assignment to...
