The field experiment compared the response to increased input of nutrients and energy (artificial detritus) to an empirical model of intra-guild predation (IGP)...

Elephant agricultural use metrics in Mara-Serengeti ecosystem

Nathan Hahn
Agricultural use metrics were calculated for 66 elephants as part of a study to characterize crop use tactics in the Mara-Serengeti ecosystem in Kenya and Tanzania. Metrics were calculated to capture mean agricultural use, maximum use from a moving average, and the difference between mean and max use. These metrics were used to classify agricultural use tactics for each elephant using Gaussian mixture models. Tables are provided with metrics and tactic classifications for the lifetime...

Landscape genomics of the streamside salamander: Implications for species management in the face of environmental change

Marc Beer, Rachael Kane, Steven Micheletti, Christopher Kozakiewicz & Andrew Storfer
Understanding spatial patterns of genetic differentiation and local adaptation is critical in a period of rapid environmental change. Climate change and anthropogenic development have led to population declines and shifting geographic distributions in numerous species. The streamside salamander, Ambystoma barbouri, is an endemic amphibian with a small geographic range that predominantly inhabits small, ephemeral streams. As A. barbouri is listed as near-threatened by the IUCN, we describe range-wide patterns of genetic differentiation and adaptation to...

Directional selection shifts trait distributions of planted species in dryland restoration

Kathleen Balazs, Seth Munson, Caroline A. Havrilla & Brad Butterfield
1. The match between species trait values and local abiotic filters can restrict community membership. An often-implicit assumption of this relationship is that abiotic filters select for a single locally optimal strategy, though difficulty in isolating effects of the abiotic environment from those of dispersal limitation and biotic interactions has resulted in few empirical tests of this assumption. Similar constraints have made it difficult to assess whether the type and intensity of abiotic filters shift...

Functional diversity response to geographic and experimental precipitation gradients varies with plant community type

Xiaoan Zuo, Shenglong Zhao, Huan Cheng, Ya Hu, Shaokun Wang, Ping Yue, Renrao Liu, Alan K. Knapp, Melinda D. Smith, Qiang Yu, Sally E. Koerner & Liu Renrao
Precipitation is a primary determinant of plant community structure in drylands. However, the empirical evidence and predictions are lacking for how plant functional diversity in desert and steppe communities respond to altered precipitation regimes. We examined how precipitation changes along the natural and experimental gradients affect different components of functional diversity in desert-shrub and steppe-grass communities. We compared the associations of precipitation changes with community-weighted means (CWM) of six traits, functional divergence (FDvar) of each...

Data from: Effects of Bark Beetle Outbreaks on Forest Landscape Pattern in the Southern Rocky Mountains, U.S.A.

Kyle Rodman, Robert Andrus, Cori Butkiewicz, Teresa Chapman, Nathan Gill, Brian Harvey, Dominik Kulakowski, Niko Tutland, Thomas Veblen & Sarah Hart
Since the late 1990s, extensive outbreaks of native bark beetles (Curculionidae: Scolytinae) have affected coniferous forests throughout Europe and North America, driving changes in carbon storage, wildlife habitat, nutrient cycling, and water resource provisioning. Remote sensing is a crucial tool for quantifying the effects of these disturbances across broad landscapes. In particular, Landsat time series (LTS) are increasingly used to characterize outbreak dynamics, including the presence and severity of bark beetle-caused tree mortality, though broad-scale...

Data from: Flower consumption, ambient temperature and rainfall modulate drinking behavior in a folivorous-frugivorous arboreal mammal

Óscar M. Chaves, Vanessa B. Fortes, Gabriela P. Hass, Renata B. Azevedo, Kathryn E. Stoner & Júlio César Bicca-Marques
In these datasets we provided information on the drinking behavior in 14 wild groups of brown howler monkeys (Alouatta guariba clamitans) inhabiting small, medium, and large Atlantic Forest fragments in southern Brazil. We provided two datasets: (1) full data on the drinking behavior of the 14 study groups, and (2) the dataset used to run the GLMMs described in the main manuscript. Overall, we found a wide variation in the mean rate of drinking among...

The cost of travel: how dispersal ability limits local adaptation in host-parasite interactions

Pieter Johnson, Dana Calhoun, Wynne Moss, Travis McDevitt-Galles, Tawni Riepe, Joshua Hallas, Thomas Parchman, Chris Feldman, Josh Cropanzano, Jay Bowerman, Tyler Achatz, Vasyl Tkach & Janet Koprivnikar
Classical theory suggests that parasites will exhibit higher fitness in sympatric relative to allopatric host populations (local adaptation). However, evidence for local adaptation in natural host-parasite systems is often equivocal, emphasizing the need for cross-infection experiments conducted over realistic geographic scales and comparisons among species with varied life history traits. Here, we conducted cross-infection experiments to test how two trematode (flatworm) species (Paralechriorchis syntomentera and Ribeiroia ondatrae) with differing dispersal abilities varied in the strength...

Invigoration or enervation? Figure data and code

Adele Igel & Susan Van Den Heever
This repository contains the figure data and code required to generate the figures that appear in Igel and van den Heever (2021) Invigoration or enervation of convective clouds by aerosols? in Geophysical Research Letters. We present new theoretical calculations which starkly contrast previous results. Prior foundational work suggested that aerosols strongly invigorate convective cloud updrafts via changes to cold-phase processes. We show that the peak magnitude of invigoration by this mechanism is substantially reduced for...

Socio-ecological drivers of public conservation voting: restoring gray wolves to Colorado, USA

Mark Ditmer, Rebecca Niemiec, George Wittemyer & Kevin Crooks
Understanding factors that influence real-world public conservation behaviors is critical for developing successful conservation policies and management actions. Citizens of Colorado, USA recently passed a ballot initiative to restore the gray wolf to its former range within the state. The >3 million votes offer an unprecedented opportunity to test factors that influenced decisions to support or oppose this conservation action. We created spatial linear regression models to assess the relationship between support for wolf restoration...

Probability of occurrence and phenology of pine wilt disease transmission by insect vectors in the Rocky Mountains

David Atkins, Seth Davis & Jane Stewart
1. Pine wilt disease, caused by pinewood nematode (Bursaphelenchus xylophilus; PWN), is a damaging and globally distributed insect-vectored forest pathogen. Native forest tree mortality associated with PWN is newly reported from the Front Range of Colorado, but there is no regional information on PWN frequency or biology of local insect vectors, limiting management options. 2. A sampling array was established to survey PWN in native pines (Pinus ponderosa) and longhorn beetles (Monochamus clamator & Monochamus...

Pathway enrichments from untargeted metabolomics of plasma of Peromyscus leucopus and Mus musculus with or without LPS treatment

Alan Barbour, Nurul Islam, Ana Milovic & John Belisle
Animals that are competent reservoirs of zoonotic pathogens commonly suffer little morbidity from the infections. To investigate mechanisms of this tolerance of infection, we used single-dose lipopolysaccharide (LPS) as an experimental model of inflammation and compared the responses by two rodents: Peromyscus leucopus, white-footed deermouse and reservoir for agents of Lyme disease and other zoonoses, and the house mouse Mus musculus. Four hours after injection with LPS or saline, blood, spleen and liver samples were...

Bird strikes at commercial airports explained by citizen science and weather radar data

Cecilia Nilsson, Frank La Sorte, Adriaan Dokter, Kyle Horton, Benjamin Van Doren, Jeffrey Kolodzinski, Judy Shamoun-Baranes & Andrew Farnsworth
1. Aircraft collisions with birds span the entire history of human aviation, including fatal collisions during some of the first powered human flights. Much effort has been expended to reduce such collisions, but increased knowledge about bird movements and species occurrence could dramatically improve decision support and proactive measures to reduce them. Migratory movements of birds pose a unique, often overlooked, threat to aviation that is particularly difficult for individual airports to monitor and predict:...

Resources do not limit compensatory response of a tallgrass prairie plant community to the loss of a dominant species

Francis Chaves &
The effect of species loss on ecosystem productivity is determined by both the functional contribution of the species lost, and the response of the remaining species in the community. According to the mass-ratio hypothesis, the loss of a dominant plant species, which has a larger proportionate contribution to productivity, is expected to exert an overwhelming effect on this important ecosystem function. However, via competitive release, loss of a dominant species can provide the opportunity for...

Winds aloft over three water bodies influence spring stopover distributions of migrating birds along the Gulf of Mexico coast

Hannah Clipp, Jeffrey Buler, Jaclyn Smolinsky, Kyle Horton, Andrew Farnsworth & Emily Cohen
Migrating birds contend with dynamic wind conditions that ultimately influence most aspects of their migration, from broad-scale movements to individual decisions about where to rest and refuel. We used weather surveillance radar data to measure spring stopover distributions of northward migrating birds along the northern Gulf of Mexico coast and found a strong influence of winds over non-adjacent water bodies, the Caribbean Sea and Atlantic Ocean, along with the contiguous Gulf of Mexico. Specifically, we...

Synthesis of Red-cockaded Woodpecker management strategies and suggestions for regional specificity in future management

Franco Gigliotti, Emily Martin & Paige Ferguson
The Red-cockaded Woodpecker ( Dryobates borealis , RCW) was listed under the U.S. Endangered Species Act in 1973 due to significant population declines resulting from habitat loss and fragmentation, and the species has been intensively managed since then. We reviewed management strategies commonly used to conserve the RCW, emphasizing studies conducted after publication of the most recent Recovery Plan in 2003, to evaluate the efficacy of each strategy across the RCW’s range and identify demographic...

Daily abundance of Dall's sheep peaks during late summer in a seasonal habitat of high-management interest

Cody E. Deane, Barrett A. Flynn, Darren L. Bruning, Greg A. Breed & Kim A. Jochum
Informing conservation and management decisions for habitats frequented by species of high management interest often face the challenge of limited resources for conducting wildlife surveys. When surveys are focused on local areas or sparsely distributed species, it may also be difficult to obtain counts sufficient for implementing abundance models that account for imperfect detection. With replicated aerial surveys collected within a 70.25 km2 portion of the Eastern Alaska Range, Alaska, USA during the summers of...

North Pacific harbor porpoise SNP and microhaplotype genotypes, mitochondrial control region haplotype sequences

Phillip Morin, Brenna Forester, Karin Forney, Carla Crossman, Brittany Hancock-Hanser, Kelly Robertson, Lance Barrett-Lennard, Robin Baird, John Calambokidis, Pat Gearin, Bradley Hanson, Cassie Schumacher, Timothy Harkins, Michael Fontaine, Barbara Taylor & Kim Parsons
Harbor porpoises in the North Pacific are found in coastal waters from southern California to Japan, but population structure is poorly known outside of a few local areas. We used multiplexed amplicon sequencing of 292 loci and genotyped clusters of SNPs as microhaplotypes (N=271 samples) in addition to mtDNA sequence data (N=413 samples), to examine the genetic structure from samples collected along the Pacific coast and inland waterways from California to southern British Columbia. We...

Demographic responses to climate change in a threatened Arctic species

Kylee D. Dunham, Anna M. Tucker, David N. Koons, Asheber Abebe, F. Stephen Dobson & James B. Grand
The Arctic is undergoing rapid and accelerating change in response to global warming, altering biodiversity patterns and ecosystem function across the region. For Arctic endemic species, our understanding of the consequences of such change remains limited. Spectacled eiders (Somateria fischeri), a large Arctic sea duck, use remote regions in the Bering Sea, Arctic Russia, and Alaska throughout the annual cycle making it difficult to conduct comprehensive surveys or demographic studies. Listed as Threatened under the...

Predator-prey interactions of terrestrial invertebrates are determined by predator body size and species identity

Ana Miller-Ter Kuile, Austen Apigo, An Bui, Bartholomew DiFiore, Elizabeth Forbes, Michelle Lee, Devyn Orr, Daniel Preston, Rachel Behm, Taylor Bogar, Jasmine Childress, Rodolfo Dirzo, Maggie Klope, Kevin Lafferty, John McLaughlin, Marisa Morse, Carina Motta, Kevin Park, Katherine Plummer, David Weber, Ronald Young & Hillary Young
Predator-prey interactions shape ecosystem and can help maintain biodiversity. However, for many of the earth’s most biodiverse and abundant organisms, including terrestrial arthropods, these interactions are difficult or impossible to observe directly with traditional approaches. Based on previous theory, it is likely that predator-prey interactions for these organisms are shaped by a combination of predator traits, including body size and species-specific hunting strategies. In this study, we combined diet DNA metabarcoding data of 173 individual...

Genotyping-by-sequencing data for a Haitian sorghum breeding program

Geoffrey Morris, Terry Felderhoff, Noah Winans, Rachel Walstead, Jean Rigaud Charles, Gael Pressoir & Kebede Muleta
Rapid environmental change can lead to extinction of populations or evolutionary rescue via genetic adaptation. In the past several years, smallholder and commercial cultivation of sorghum (Sorghum bicolor), a global cereal and forage crop, has been threatened by a global outbreak of an aggressive new biotype of sugarcane aphid (SCA; Melanaphis sacchari). Here we characterized genomic signatures of adaptation in a Haitian sorghum breeding population, which had been recently founded from admixed global germplasm, extensively...

Data from: Infection prevalence and density of a pathogenic trematode parasite decrease with stream order along a river continuum

Landon Falke & Daniel Preston
In lotic ecosystems, the River Continuum Concept (RCC) provides a framework for understanding changes in environmental factors and free-living communities, yet how parasite populations shift along river continua remains less clear. We quantified infections by a pathogenic trematode parasite (Nanophyetus salmincola) in >14,000 host snails across 130 stream reaches spanning 165 km in the Willamette River Basin in western Oregon, USA. Environmental factors – including flow volume, temperature, benthic algae, canopy cover, woody debris, and...
