Effects of Direct and Indirect Predator Cues on Heteromyid Seed Selection and Seed Fate Open

Kelly J. Sivy · 2021

Many factors affect foraging behavior of rodents, including predation risk, which is thought to influence seed selection and seed handling by desert rodents in patchy environments. Understanding forces that drive seed selection and seed fa…

Gifts of an enemy: scavenging dynamics in the presence of wolves (<i>Canis lupus</i>) Open

Kaija J Klauder, Bridget L. Borg, Kelly J. Sivy, Laura R. Prugh · 2021

Carrion represents an important resource for carnivores. Examining competition for carrion in a risk–reward framework allows for a better understanding of how predator guilds compete for and benefit from carrion. We used trail camera data …

Enemies with benefits: integrating positive and negative interactions among terrestrial carnivores Open

Laura R. Prugh, Kelly J. Sivy · 2020

Interactions among terrestrial carnivores involve a complex interplay of competition, predation and facilitation via carrion provisioning, and these negative and positive pathways may be closely linked. Here, we developed an integrative fr…

Spring food habits of Wolverine (<i>Gulo gulo</i>) in the Colville River watershed, Alaska Open

Ross R. Dorendorf, Kelly J. Sivy, Martin D. Robards, Thomas W. Glass, Kristine L. Pilgrim · 2019

Wolverines (Gulo gulo) are relatively abundant on the North Slope of Alaska, an Arctic ecosystem dominated by tundra habitats that run north from the Brooks Range across a wide coastal plain to the Beaufort Sea. The region contains a range…

Snow Depth, Stratigraphy, and Temperature in Wrangell St Elias NP, Alaska, 2016-2018 Open

Christopher Cosgrove, Laura R. Prugh, A. W. Nolin, Kelly J. Sivy, Ryan Crumley , et al. · 2019

This dataset includes data from late-March snow surveys and hourly digital camera images from two study areas within the Wrangell St Elias National Park, Alaska. These data comprise snow density, stratigraphy, and temperature profiles obta…

Designing studies of predation risk for improved inference in carnivore-ungulate systems Open

Laura R. Prugh, Kelly J. Sivy, Peter J. Mahoney, Taylor R. Ganz, Mark A. Ditmer , et al. · 2019

Quantifying both the lethal and non-lethal (or “risk”) effects of predation has emerged as a major research focus in carnivore-ungulate systems. While numerous studies have examined predation risk and risk effects in recent decades, a lack…

ABoVE: Dall Sheep Lamb Recruitment and Climate Data, Alaska and NW Canada, 2000-2015 Open

Madelon van de Kerk, David L. Verbyla, A. W. Nolin, Kelly J. Sivy, Laura R. Prugh · 2018

This dataset contains estimated annual average Dall sheep (Ovis dalli dalli) lamb-to-ewe ratios for each year from 2000-2015 across the full species range in Alaska and Northwestern Canada. Sheep population data are from surveys conducted …

Range-wide variation in the effect of spring snow phenology on Dall sheep population dynamics Open

Madelon van de Kerk, David L. Verbyla, A. W. Nolin, Kelly J. Sivy, Laura R. Prugh · 2018

Understanding the underlying mechanisms of species distributions and range limits is critical to predicting species responses to climate change. The relationship between climate factors and population performance is often assumed to be con…

ABoVE: Dall Sheep Track Sinking Depths, Snow Depth, Hardness, and Density, 2017 Open

Kelly J. Sivy, A. W. Nolin, Christopher Cosgrove, Laura R. Prugh · 2018

This dataset contains Dall sheep (Ovis dalli dalli) hoof sinking depths in snow tracks, and snow depth, hardness, and density measurements in snow pits adjacent to the tracks. Snow measurements were collected between March 19-22, 2017 at s…

Data from: Apex predators and the facilitation of resource partitioning among mesopredators Open

Kelly J. Sivy, Casey B. Pozzanghera, Kevin E. Colson, Matthew A. Mumma, Laura R. Prugh · 2017

Apex predators may influence carnivore communities through the suppression of competitively dominant mesopredators, however they also provide carrion subsidies that could influence foraging and competition among sympatric mesopredators whe…

Coyote and red fox scat contents Open

Kelly J. Sivy, Casey B. Pozzanghera, Kassidy Colson, Matthew A. Mumma, Laura R. Prugh · 2017

This file contains data of percent volume of items found in 471 coyote and red fox scats collected in interior Alaska, winter 2013-2014. Scat number refers to the sample number, Study refers to the study area from which the scat was colle…

Socioeconomic Benefits of Large Carnivore Recolonization Through Reduced Wildlife‐Vehicle Collisions Open

Sophie L. Gilbert, Kelly J. Sivy, Casey B. Pozzanghera, Adam J. Dubour, Kelly S Overduijn , et al. · 2016

The decline of top carnivores has released large herbivore populations around the world, incurring socioeconomic costs such as increased animal–vehicle collisions. Attempts to control overabundant deer in the Eastern United States have lar…
