Concordant patterns of morphological, stable isotope, and genetic variation in a recent ecological radiation (Salmonidae:Coregonus spp.)

Moisés Bernal, Daniel Yule, Wendylee Stott, Lori Evrard, Thomas Dowling & Trevor Krabbenhoft
Groups of sympatric taxa with low inter-specific genetic differentiation, but considerable ecological differences, offer great opportunities to study the dynamics of divergence and speciation. This is the case of ciscoes (Coregonus spp.) in the Laurentian Great Lakes, which are characterized by a complex evolutionary history and are commonly described as having undergone an adaptive radiation. In this study, morphometrics, stable isotopes and transcriptome sequencing were used to study the relationships within the Coregonus artedi complex...

Data from: Range-wide population genetic analysis of Seaside Sparrows (Ammospiza maritima) supports at least five distinct population segments that do not align with current subspecies descriptions

Amie Settlecowski, Kathryn Davis, Mackenzie Roeder, Carolyn Enloe, Thomas Virzi, Margaret Hunter, Stefan Woltmann & Sabrina Taylor
As an obligate salt marsh species, Seaside Sparrows (Ammospiza maritima) are vulnerable to numerous threats including climate change, coastal erosion, sea level rise, and both natural and anthropogenic disasters. Of the nine recognized subspecies, two are extinct and one is endangered. Previous genetic analyses of mitochondrial DNA (mtDNA) and microsatellite loci showed that current taxonomy does not accurately reflect underlying genetic diversity, with possible consequences for the distribution of conservation resources. To further inform Seaside...

Over the hills and through the farms: Land use and topography influence genetic connectivity of northern leopard frog (Rana pipiens) in the Prairie Pothole Region

Justin Waraniak, David Mushet & Craig Stockwell
Context Agricultural land-use conversion has fragmented prairie wetland habitats in the Prairie Pothole Region (PPR), an area with one of the most wetland-dense regions in the world. This fragmentation can lead to negative consequences for wetland obligate organisms, heightening risk of local extinction and reducing evolutionary potential for populations to adapt to changing environments. Objectives This study models biotic connectivity of prairie-pothole wetlands using landscape genetic analyses of the northern leopard frog (Rana pipiens) to:...

Changes in habitat suitability for wintering dabbling ducks during dry conditions in the Central Valley of California

Erin Conlisk, Kristin Byrd, Elliott Matchett, Austen Lorenz, Michael Casazza, Gregory Golet, Mark Reynolds, Kristin Sesser & Matthew Reiter
In arid and Mediterranean regions, landscape-scale wetland conservation requires understanding how wildlife responds to dynamic freshwater availability and human actions to enhance wetland habitat. Taking advantage of the Landsat satellite time series (2007–2016) and structured and community science bird survey data, we built species distribution models to describe how three duck species – Northern Pintail (Anas acuta), Green-winged Teal (A. crecca), and Northern Shoveler (A. clypeata) – respond to freshwater supply and food resources on...

Caution is warranted when using animal space-use and movement to infer behavioral states

Frances E. Buderman, Tess M. Gingery, Duane R. Diefenbach, Laura C. Gigliotti, Danielle Begley-Miller, Marc M. McDill, Bret D. Wallingford, Christopher S. Rosenberry & Patrick J. Drohan
Background: Identifying the behavioral state for wild animals that can’t be directly observed is of growing interest to the ecological community. Advances in telemetry technology and statistical methodologies allow researchers to use space-use and movement metrics to infer the underlying, latent, behavioral state of an animal without direct observations. For example, researchers studying ungulate ecology have started using these methods to quantify behaviors related to mating strategies. However, little work has been done to determine...

Riparian buffers provide refugia during secondary forest succession

Michelle E. Thompson, Brian J. Halstead & Maureen A. Donnelly
Aim Secondary forests regenerating from human disturbance are increasingly becoming a predominant forest type in many regions, and they play a significant role in forest community dynamics. Understanding the factors that underlie the variation in species responses during secondary succession is important for understanding community assembly and biodiversity monitoring and management. Because species vary in ecology and behavior, responses to ecosystem change should vary among species. Here, we show that habitat type (riparian, upland), phylogeny,...

Sharing land via keystone structure: retaining naturally regenerated trees may efficiently benefit birds in plantations

Yuichi Yamaura, Akira Unno & J. Royle
Meeting food/wood demands with increasing human population and per-capita consumption is a pressing conservation issue, and is often framed as a choice between land sparing and land sharing. Although most empirical studies comparing the efficacy of land sparing and sharing supported land sparing, land sharing may be more efficient if its performance is tested by rigorous experimental design and habitat structures providing crucial resources for various species––keystone structures––are clearly involved. We launched a manipulative experiment...

Data from: Predation probabilities and functional responses: How piscivorous waterbirds respond to pulses in fish abundance

Nathan Hostetter, Quinn Payton, Daniel Roby, Ken Collis & Allen Evans
How predators respond to changes in prey abundance (i.e. functional responses) is foundational to consumer-resource interactions, predator-prey dynamics, and the stability of predator-prey systems. Predation by piscivorous waterbirds on out-migrating juvenile steelhead trout (Oncorhynchus mykiss) is considered a factor affecting the recovery of multiple Endangered Species Act-listed steelhead populations in the Columbia River basin. Waterbird functional responses, however, may vary by predator species and location, with important implications to predator management strategies. We used a...

Functional composition of plant communities mediates biomass effects on ecosystem service recovery across an experimental dryland restoration network

Bradley Butterfield, Kathleen Balazs & Seth Munson
Land degradation can result in a loss of critical ecosystem services that we often seek to restore through re-establishment of desired plant communities. Trait-based approaches have the potential to target specific ecosystem services based on associations between the functional composition of plant communities and ecosystem properties that serve as indicators of those services. The effect of functional composition on ecosystem recovery may depend on the amount of restored plant biomass, itself a supporting service frequently...

Interannual variation in climate contributes to contingency in post-fire restoration outcomes in seeded sagebrush steppe

Allison Simler-Williamson, Cara Applestein & Matthew Germino
Interannual variation, especially weather, is an often-cited reason for restoration “failures”; yet its importance is difficult to experimentally isolate across broad spatiotemporal extents, due to correlations between weather and site characteristics. In the analysis associated with this dataset, we examined post-fire treatments within sagebrush-steppe ecosystems to ask: 1) Is weather following seeding efforts a primary reason why restoration outcomes depart from predictions? and 2) Does the management-relevance of weather differ across space and with time...

Compensatory recruitment unlikely in high elevation amphibian populations challenged with disease

Bennett Hardy, Erin Muths, Bradley Lambert, Scott Schneider, Chris Funk & Larissa Bailey
Population-level variation in host responses to disease can be observed across a wide array of host-pathogen systems. Some host populations are extirpated, some persist at lower densities or abundances, and others rebound to pre-disease levels. Understanding the causes of this variation, and the mechanisms of successful persistence, can serve as vital information for species conservation. One such mechanism of population persistence that has gained support in the amphibian Batrachochytrium dendrobatidis (Bd) host-pathogen system is the...

Global analysis of environmental and socioeconomic factors associated with human burden of environmentally mediated pathogens

Susanne Sokolow, Isabel Jones, Chelsea Wood, Kevin Lafferty, Andres Garchitorena, Skylar Hopkins, Andrea Lund, Andrew MacDonald, Nicole Nova, Chris LeBoa, Alison Peel, Erin Mordecai, Meghan Howard, Julia Buck, David Lopez-Carr, Michele Barry, Matthew Bonds & Giulio De Leo
This repository contains four datasets that support repeatability of the analyses in the Sokolow et al. paper published in Lancet Planetary Health. Descriptions of the four datasets are included in the metadata document. This study found that 80% of pathogen species known to infect humans are environmentally mediated, causing about 40% of contemporary infectious-disease burden (global loss of 130 million years of healthy life annually). More than 91% of this environmentally-mediated disease burden occurs in...

Local weather and endogenous factors affect the initiation of migration in short- and medium-distance songbird migrants

Theodore Zenzal, Darren Johnson, Frank Moore & Zoltan Nemeth
Migratory birds employ a variety of mechanisms to ensure appropriate timing of migration based on the integration of endogenous and exogenous information. The cues to fatten and depart from the non-breeding area are often linked to exogenous cues such as temperature or precipitation and the endogenous program. Shorter-distance migrants should rely heavily on environmental information when initiating migration given the relatively close proximity to the breeding area. However, the ability to fatten and subsequently depart...

Invasive predator diet plasticity has implications for native fish conservation & invasive species suppression

Hayley Glassic, Christopher Guy, Dominique Lujan, Lusha Tronstad, Michelle Briggs, Lindsey Albertson & Todd Koel
Diet plasticity is a common behavior exhibited by piscivores to sustain predator biomass when preferred prey biomass is reduced. Invasive piscivore diet plasticity could complicate suppression success; thus, understanding invasive predator consumption is insightful to meeting conservation targets. Here, we determine if diet plasticity exists in an invasive apex piscivore and how plasticity could influence native species recovery benchmarks and invasive species suppression goals. We compared diet and stable isotope signatures of invasive lake trout...

Data from: Haploid gynogens facilitate disomic marker development in paleotetraploid sturgeons

Richard Flamio, Dominic G. Swift, David S. Portnoy, Kimberly A. Chojnacki, Aaron J. DeLonay, Jeffrey Powell, Patrick J. Braaten & Edward J. Heist
Acipenseriformes (sturgeons and paddlefishes) are of substantial conservation concern, and development of genomic resources for these species is difficult due to past whole genome duplication. Development of disomic markers for polyploid organisms can be challenging due to difficulty in resolving alleles at a single locus from those among duplicated loci. In this study, we detail the development of disomic markers for the endangered pallid sturgeon (Scaphirhynchus albus) found in North America. One of the strategies...

Data from: A migratory divide spanning two continents is associated with genomic and ecological divergence

Sheela Turbek, Drew Schield, Elizabeth Scordato, Andrea Contina, Xin-Wei Da, Yang Liu, Yu Liu, Emilio Pagani-Núñez, Qing-Miao Ren, Chris Smith, Craig Stricker, Michael Wunder, David Zonana & Rebecca Safran
Migratory divides are contact zones between breeding populations with divergent migratory strategies during the non-breeding season. These locations provide an opportunity to evaluate the role of seasonal migration in the maintenance of reproductive isolation, particularly the relationship between population structure and features associated with distinct migratory strategies. We combine light-level geolocators, genomic sequencing, and stable isotopes to investigate the timing of migration and migratory routes of individuals breeding on either side of a migratory divide...

Integrated animal movement and spatial capture-recapture models: simulation, implementation, and inference

Beth Gardner, Brett McClintock, Sarah Converse & Nathan Hostetter
Over the last decade, spatial capture-recapture (SCR) models have become widespread for estimating demographic parameters in ecological studies. However, the underlying assumptions about animal movement and space use are often not realistic. This is a missed opportunity because ecological questions related to animal space use, habitat selection, and behavior cannot be addressed with most SCR models, despite the fact that the data collected in SCR studies -- individual animals observed at specific locations and times...

Quantifying the relationship between prey density, livestock and illegal killing of leopards

Mahmood Soofi, Ali Turk Qashqaei, Marzieh Mousavi, Ehsan Hadipour, Marc Filla, Bahram Hasanzadeh Kiabi, Benjamin Bleyhl, Arash Ghoddousi, Niko Balkenhol, Andrew Royle, Chris R. Pavey, Igor Khorozyan & Matthias Waltert
Many large mammalian carnivores are facing population declines due to illegal killing (e.g., shooting) and habitat modification (e.g., livestock farming). Illegal killing occurs cryptically and hence is difficult to detect. However, reducing illegal killing requires a solid understanding of its magnitude and underlying drivers, while accounting for the imperfect detection of illegal killing events. Despite the importance of illegal killing of large carnivores in comparison with other causes of mortality, its relationship with potential drivers...

Data from: Estimating bee abundance: Can mark-recapture methods validate common sampling protocols?

Emma Briggs, Christopher Baranski, Olivia Münzer Schaetz, Gabriela Garrison, Jaime Collazo & Elsa Youngsteadt
Wild bees can be essential pollinators in natural, agricultural, and urban systems, but populations of some species have declined. Efforts to assess the status of wild bees are hindered by uncertainty in common sampling methods, such as pan traps and aerial netting, which may or may not provide a valid index of abundance across species and habitats. Mark-recapture methods are a common and effective means of estimating population size, widely used in vertebrates but rarely...

Population genetics reveals bidirectional fish movement across the Continental Divide via an interbasin water transfer

Audrey Harris, Sara Oyler-McCance, Jennifer Fike, Matthew Fairchild, Christopher Kennedy, Harry Crockett, Dana Winkelman & Yoichiro Kanno
Interbasin water transfers are becoming an increasingly common tool to satisfy municipal and agricultural water demand, but their impacts on movement and gene flow of aquatic organisms are poorly understood. The Grand Ditch is an interbasin water transfer that diverts water from tributaries of the upper Colorado River on the west side of the Continental Divide to the upper Cache la Poudre River on the east side of the Continental Divide. We used single nucleotide...

Seaside Sparrow nest location, fate, and nest predator distribution data

Elizabeth Hunter
Nest failure for coastal marsh bird species is primarily caused by predation and nest flooding. As sea level rise makes nest flooding more likely, the threat of nest predation will constrain the potential adaptive responses of marsh nesting species. Thus, understanding the predictors of nest predation is important for the conservation of salt marsh-dwelling bird species, such as Seaside Sparrows (Ammospiza maritima; SESP). Predator activity may be influenced by landscape features (particularly habitat edges), potentially...

Redwood Creek Chinook salmon life cycle model code and data

Emily Chen, Nicholas Som, John Deibner-Hanson, David Anderson & Mark Henderson
Understanding the spatial and temporal habitat use of a population is a necessary step for restoration decision making. For Chinook salmon (Oncorhynchus tshawytscha), variation in their migration and habitat use complicate predicting how restoring habitats will impact total recruitment. To evaluate how juvenile life history variation affects a population’s response to potential restoration, we developed a stage-structured model for a Chinook salmon population in a northern California river with a seasonally closed estuary. We modeled...

Confirmation that eagle fatalities can be reduced by automated curtailment of wind turbines

Christopher McClure, Brian Rolek, Leah Dunn, Jennifer McCabe, Luke Martinson & Todd Katzner
1. Automated curtailment is potentially a powerful technique to reduce collision mortality of wildlife with wind turbines. Previously, we used a before-after-control-impact framework to demonstrate that eagle fatalities declined after automated curtailment was implemented with the IdentiFlight system at a wind power facility in Wyoming, USA. We received substantial interest and feedback regarding our study and, here, we implement several analytical suggestions and include more recent data that strengthen the inference we draw from our...
