Data from: Overlap of spatial and temporal spawning distributions of spring and summer Chinook Salmon results in hybridization in the upper Columbia River

Gregory Fraser, Patrick DeHaan, Christian Smith, Jennifer Von Bargen, Mathew Cooper & Thomas Desgrosseillier
The upper Columbia River in Washington State (main-stem and tributary habitat between McNary and Chief Joseph dams) is inhabited by two major lineages of Chinook Salmon (Oncorhynchus tshawytscha); endangered spring Chinook Salmon and summer Chinook Salmon which are not ESA listed. The lineages are highly genetically divergent from one another and historically spatial and temporal isolating mechanisms maintained these genetic differences. Both lineages occur in the Entiat River, a system where anthropogenic activity has changed...

Proximity to oil wells in North Dakota does not impact nest success of ducks but lowers nest densities

Kevin Ringelman, Cassandra Skaggs, Charles Loesch, Michael Szymanski, Frank Rohwer & Kaylan Kemink
Over the past decade, the United States has seen a rapid increase in oil and gas extraction from areas where resources were previously thought to be unrecoverable, particularly the Bakken shale formation in North Dakota. The Bakken overlaps with the Prairie Pothole Region, the most critical habitat in North America for breeding ducks, where oil and gas extraction through hydraulic fracturing has the potential to impact more than a million duck pairs in the United...

Panmixia in a sea ice-associated marine mammal: evaluating genetic structure of the Pacific walrus (Odobenus rosmarus divergens) at multiple spatial scales

The dataset includes 5303 Pacific walrus genotypes for 114 single nucleotide polymorphisms used in the manuscript "Panmixia in a sea ice-associated marine mammal: evaluating genetic structure of the Pacific walrus (Odobenus rosmarus divergens) at multiple spatial scales". Biopsy samples were collected from Pacific walruses hauled-out on sea ice in the Bering and Chukchi seas from 2013-2017 in June of each year. Genotypes are presented in two columns per locus and missing data is coded as...

Using incidental mark-encounter data to improve survival estimation

Seth Harju, Scott Cambrin, Roy Averill-Murray, Melia Nafus, Kimberleigh Field & Linda Allison
1. Obtaining robust survival estimates is critical, but sample size limitations often result in imprecise estimates or the failure to obtain estimates for population subgroups. Concurrently, data are often recorded on incidental re-encounters of marked individuals, but these incidental data are often unused in survival analyses. 2. We evaluated the utility of supplementing a traditional survival dataset with incidental data on marked individuals that were collected ad-hoc. We used a continuous time-to-event exponential survival model...

David M. Latham, Stephen Lewis, Carol McIntyre, Tricia Miller, Kelsey Russell, Dale Seip … & Judy Williams
We provide here the data used in analysis of 3 test cases, presented in the manuscript "Ecological insights from three decades of animal movement tracking across a changing Arctic". We utilized the new Arctic Animal Movement Archive (AAMA), a growing collection of 201 standardized terrestrial and marine animal tracking studies from 1991–present. The AAMA supports public data discovery, preserves fundamental baseline data for the future, and facilitates efficient, collaborative data analysis. With three AAMA-based case...

rhinoceros auklet microsatellite data

Theresa Burg, Marie Prill, Katharine Studholme, Alice Domalik, Strahan Tucker, Catherine Jardine, Mark Maftei, Kenneth Wright, Jesse Beck, Russell Bradley, Ryan Carle, Thomas Good, Scott Hatch, Peter Hodum, Motohiro Ito, Scott Pearson, Nora Rojek, Leslie Slater, Yutaka Watanuki, Alexis Will, Aidan Bindoff, Glenn Crossin, Mark Drever & Mark Hipfner
We tested the hypothesis that segregation in wintering areas promotes population differentiation in a sentinel North Pacific seabird, the rhinoceros auklet (Cerorhinca monocerata). We collected tissue samples for genetic analyses on five breeding colonies in the western Pacific Ocean (Japan) and 13 in the eastern Pacific Ocean (California to Alaska), and deployed light-level geologgers on 12 eastern Pacific colonies to delineate wintering areas. Loggers were deployed previously on one colony in Japan. There was strong...

Data from: An isolated white-tailed deer (Odocoileus virginianus) population on St. John, US Virgin Islands shows low inbreeding and comparable heterozygosity to other larger populations

Scott Taylor, Suzanne Nelson & Jon Reuter
This is the first study to document the genetic diversity of the white-tailed deer population on St. John, US Virgin Islands. The island population was founded by a small number of animals, has very limited hunting or predation, and recently experienced a reduction in size following an extended drought in 2015. DNA samples were collected from hair from 23 anesthetized adult deer (13 males, 10 females) ranging in age from 1-8 years (3.36+ 1.9 yr)...

Diurnal timing of nonmigratory movement by birds: the importance of foraging spatial scales

Julie Mallon, Marlee Tucker, Annalea Beard, , Keith Bildstein, Katrin Böhning-Gaese, John Brzorad, Evan Buechley, Javier Bustamante, Carlos Carrapato, José Castillo-Guerrero, Elizabeth Clingham, Mark Desholm, Christopher DeSorbo, Robert Domenech, Hayley Douglas, Olivier Duriez, Peter Enggist, Nina Farwig, Wolfgang Fiedler, Anna Gagliardo, Clara García-Ripollés, Juan Antonio Gil, Morgan Gilmour, Roi Harel … & Bill Fagan
Timing of activity can reveal an organism’s efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to...

Efficacy of cover crops for pollinator habitat provision and weed suppression

Karla Gage, Casey Bryan, Sedonia Sipes, Mike Arduser, Leila Kassim, David Gibson & Drew Scott
Pollinator declines have been documented globally, but little information is available about native bee ecology in Midwestern US agriculture. This project seeks to optimize pollinator support and weed suppression in a 3-year crop rotation with a fallow growing season. During fallow, one of five cover crop treatments (T1: crimson, red, and ladino clover and Bob oats [Trifolium incarnatum, T. pratense, T. repens, Avena sativa]; T2: crimson clover and oats; T3: red clover and oats; T4:...

Data from: Quantifying spatiotemporal occupancy dynamics and multi-year core-use areas at a species range boundary

Nathan Hostetter, Daniel Ryan, David Grosshuesch, Timothy Catton, Sarah Malick-Wahls, Tamara Smith & Beth Gardner
Aim Many species face large-scale range contractions and predicted distributional shifts in response to climate change, shifting forest characteristics, and anthropogenic disturbances. Canada lynx (Lynx canadensis) are listed as threatened under the U.S. Endangered Species Act and were recently recommended for delisting. Predicted climate-driven losses in habitat quality and quantity may negatively affect the northeastern Minnesota lynx population, one of six remaining resident populations in the contiguous United States. We develop a large-scale monitoring protocol...

Seasonal survival and reversible state effects in a long-distance migratory shorebird

Rose Swift, Amanda D. Rodewald, James Johnson, Brad Andres & Nathan Senner
1. Events during one stage of the annual cycle can reversibly affect an individual’s condition and performance not only within that stage, but also in subsequent stages (i.e., reversible state effects). Despite strong conceptual links, however, few studies have been able to empirically link individual-level reversible state effects with larger-scale demographic processes. 2. We studied both survival and potential reversible state effects in a long-distance migratory shorebird, the Hudsonian Godwit (Limosa haemastica). Specifically, we estimated...

Evaluation of the Impacts of Radio-Marking Devices on Feral Horses and Burros in a Captive Setting

Kathryn A. Schoenecker, Sarah R. B. King & Gail H. Collins
Radio-collars and other radio-marking devices have been invaluable tools for wildlife managers for >40 years. These marking devices have improved our understanding of wildlife spatial ecology and demographic parameters and provided new data facilitating model development for species conservation and management. Although these tools have been used on virtually all North American ungulates, their deployment on feral horses (Equus ferus caballus) or burros (E. asinus) has been limited. To determine if radio-collars and radio-tags could...

Data from: Effects of arthropod inquilines on growth and reproductive effort among metacommunities of the purple pitcher plant (Sarracenia purpurea var. montana)

Rebecca Hale, Elise Powell, Leila Beikmohamadi & Mara Alexander
Many plant species harbor communities of symbionts that release nutrients used by their host plants. However, the importance of these nutrients to plant growth and reproductive effort is not well understood. Here, we evaluate the relationship between the communities that colonize pitcher plant phytotelmata and the pitcher plants’ vegetative growth and flower production to better understand the symbiotic role played by phytotelma communities. We focus on the mountain variety purple pitcher plant (Sarracenia purpurea var....

Habitat openness and edge avoidance predict saltmarsh sparrow abundance better than habitat area

Hallie Marshall, Erik Blomberg, Valerie Watson, Meaghan Conway, Jonathan Cohen, Maureen Correll, Chris Elphick, Thomas Hodgman, Alison Kocek, Adrienne Kovach, W. Gregory Shriver, Whitney Wiest & Brian Olsen
The Saltmarsh Sparrow (Ammospiza caudacuta) is a tidal marsh bird facing rapid population decline throughout its range, largely caused by degradation and loss of breeding habitat. Thus there is a need to preserve tidal marshes in the northeastern United States, but to do so requires an understanding of the habitat features that support robust populations. Previous studies have shown Saltmarsh Sparrow abundance increases with marsh size, but in similar bird species, area sensitivity is more...

Dunlin subspecies exhibit regional segregation and high site fidelity along the East Asian−Australasian Flyway

Benjamin Lagassé, Richard Lanctot, Mark Barter, Stephen Brown, Chung-Yu Chiang, Chi-Yeung Choi, Yuri Gerasimov, Steve Kendall, Joseph Liebezeit, Konstantin Maslovsky, Alexander Matsyna, Ekaterina Matsyna, David Payer, Sarah Saalfeld, Yoshimitsu Shigeta, Ivan Tiunov, Pavel Tomkovich, Olga Valchuk & Michael Wunder
The degree that individuals migrate among particular breeding, migration, and wintering sites can have important implications for prioritizing conservation efforts. Four subspecies of Dunlin (Calidris alpina) migrate along the East Asian−Australasian Flyway (EAAF). Each subspecies has a distinct and well-defined breeding range, but their migration and winter ranges are poorly defined or unknown. We assessed the migratory connectivity of 3 of these subspecies by evaluating a dataset that encompasses 57 years (1960–2017), and comprises more...

Supplementary materials: Monitoring recovery of overgrazed lichen communities on Hagemeister Island, southwestern Alaska

Patrick Walsh & Trevor Goward
Understanding the recovery rate of overgrazed lichen communities has value to mangers of lands in northern regions. We describe lichen community composition and present recovery rate measurements for a 12-year period following overgrazing by reindeer (Rangifer tarandus) on Hagemeister Island, Alaska. Reindeer were removed from the island in 1993 following overgrazing and average total lichen biomass increased from 504.2 kg/ha (SD 205.4) in 2003 to 795.3 (SD 489.6) in 2015. We estimate time to recovery...

Among‐family variation in survival and gene expression uncovers adaptive genetic variation in a threatened fish

Avril M. Harder, Janna R. Willoughby, William R. Ardren & Mark R. Christie
Variation in among‐family transcriptional responses to different environmental conditions can help to identify adaptive genetic variation, even prior to a selective event. Coupling differential gene expression with formal survival analyses allows for the disentanglement of treatment effects, required for understanding how individuals plastically respond to environmental stressors, from the adaptive genetic variation responsible for differential survival. We combined these two approaches to investigate responses to an emerging conservation issue, thiamine (vitamin B1) deficiency, in a...

Burrowing Owl (Athene cunicularia) nest phenology influenced by drought on nonbreeding grounds

Catie Porro, Martha Desmond, Julie Savidge, Fitsum Abadi Gebreselassie, Kirsten Cruz-McDonnell, Jennifer Davis, Randall Griebel, Rebecca Eckstein & Nancy Hernandez Rodrguez
Migratory birds are demonstrating changes in phenology linked to climate change. Understanding these changes requires connecting events that occur over the multiple regions occupied during their annual cycle. The Burrowing Owl (Athene cunicularia) is a species of concern in North America, with pronounced declines in regions of the Great Plains. Using a dataset that spanned ten breeding sites from South Dakota to northern Mexico in various years during 1989-2017, we observed both advances and delays...

Data from: Postwar wildlife recovery in an African savanna: Evaluating patterns and drivers of species occupancy and richness

Kaitlyn Gaynor, Joshua Daskin, Lindsey Rich & Justin Brashares
As local and global disturbances reshape African savannas, an understanding of how animal communities recover and respond to landscape features can inform conservation and restoration. Here, we explored the spatial ecology of a wildlife community in Gorongosa National Park, Mozambique, where conservation efforts have fostered the recovery of large mammal populations after their near‐extirpation during Mozambique’s civil war. We deployed a grid of 60 camera traps and used a hierarchical, multi‐species occupancy modeling approach to...

Response of lion demography and dynamics to the loss of preferred larger prey

Milan Vinks, Scott Creel, Paul Schuette, Matthew Becker, Elias Rosenblatt, Carolyn Sanguinetti, Kambwiri Banda, Ben Goodheart, Kim Young-Overton, Xia Stevens, Clive Chifunte, Neil Midlane & Chuma Simukonda
Large carnivores are experiencing range contraction and population declines globally. Prey depletion due to illegal offtake is considered a major contributor, but the effects of prey depletion on large carnivore demography are rarely tested. We measured African lion density and tested the factors that affect survival using mark-recapture models fit to six years of data from known individuals in Kafue National Park (KNP), Zambia. KNP is affected by prey depletion, particularly for large herbivores that...
