Introduction
My research lab aims to understand the drivers and consequences of body size change to improve sustainability for large ruminants (bison, cattle, etc.) on working and public lands in a changing world. We study bison (Bison bison) body size change using integrated methods of vertebrate paleontology, thermal biology (thermography), and ecology to inform management and to connect people with nature.

Article
Full-text available
The relationship between body size and temperature of mammals is poorly resolved, especially for large keystone species such as bison (Bison bison). Bison are well represented in the fossil record across North America, which provides an opportunity to relate body size to climate within a species. We measured the length of a leg bone (calcaneal tube...
Article
Full-text available
Bison (Bison bison) are a keystone of a conservation system, but that system is vulnerable to the effects of a changing climate projected to alter land use through the 21st century. The current bison population of North America is approximately 400,000 animals and is maintained by a self‐assembled bison management system (BMS) of various stakeholde...

Full-text available
Future climate projections of warming, drying, and increased weather variability indicate that conventional agricultural and production practices within the Northern Great Plains (NGP) will become less sustainable, both ecologically and economically. As a result, the livelihoods of people that rely on these lands will be adversely impacted. This is...

Unseasonably early blizzards in the northern Great Plains threaten large mammal populations unacclimated for variable and extreme winter conditions. This region averaged 22 blizzards per winter season during the 2010s, up from 6 during the 1960s, and is anticipated to average 32 blizzards by the 2050s. In early October 2013, the fatal Atlas Blizzar...

Fossils of Bison (bison) are scarce on the Colorado Plateau, especially in and around the Greater Grand Canyon Region. Because of poor preservation and collection biases in the region, various resource managers have erroneously designated bison a nonnative and human-(re)introduced species. This decision directly impacts an extant herd of approximat...
Conference Paper
Ecosystem function relies in part on aligned relationships between functional traits of animals and the environments in which they live. Studies of trait-environment relationships have largely focused on communities of native species, but domestic and non-native species also play a role in the functioning of modern ecosystems. We use ecometrics, or...

Several quantitative diagnostic techniques are available to estimate gastrointestinal parasite counts in the feces of ruminants. Comparing egg and oocyst magnitudes in naturally infected samples has been a recommended approach to rank fecal techniques. In this study, we compared the Mini-FLOTAC (sensitivity of 5 eggs per gram (EPG)/oocysts per gram...

Most of us are familiar with the childhood story of Goldilocks and the three bears, where the little girl tries to find the bed that wasn't too hard, nor too soft, but “just right.” This concept can be applied to many facets of life and business. For livestock, discussions and evaluation of body size, carcass weight, and dressing percentage come up...

Full-text available
Bison (Bison bison) restoration has profound implications for ecological, economic and cultural domains, especially restoration into their former historic ranges. Climate change and climate variability, however, threaten sustainable restoration progress. The historic range of bison centered on the prairies of the Great Plains but spanned from Alask...
Technical Report
Full-text available
Currently, the U.S. Department of Agriculture (USDA) considers bison (Bison bison) a non-amenable, “exotic” species. This designation has been applied because bison were first considered a native wildlife game species under states’ laws (i.e. public trust doctrine circa 1700s) and most wildlife laws pre-date agricultural laws (see Geer vs. Connecti...
Data
We reassess the historic maximum extent of where bison once naturally roamed during or near the arrival of colonial explorers to this continent. In a first demonstration of a multidisciplinary meta-analysis for a species’ extent of occurrence, we combined evidence from paleontology (fossils), archaeology (Indigenous and cultural use associated with...
Article
Full-text available
Following the near extinction of bison (Bison bison) from its historic range across North America in late 19th century, novel bison conservation efforts in the early 20th century catalyzed a popular widespread conservation movement to protect and restore bison among other species and places. Since Allen’s initial delineation (1876) of the historic...

Technical Report
Full-text available
North American bison (Bison bison) are an attractive, high-value livestock species that is growing in number and popularity across the United States. While bison ranching has some similarities with cattle ranching, there are significant differences that must be accounted for to ensure long-term sustainability and profitability. Bison are a hardy sp...

A paleontological deposit near San Clemente de Térapa represents one of the very few Rancholabrean North American Land Mammal Age sites within Sonora, Mexico. During that time, grasslands were common, and the climate included cooler and drier summers and wetter winters than currently experienced in northern Mexico. Here, we demonstrate restructurin...

Aim Mammals on islands often undergo remarkable evolutionary changes. The acquisition of ‘low gear’ locomotion, namely short and robust limb elements, has been typically associated with the island syndrome in large mammals and, especially, ruminants. Here we provide an investigative framework to examine biotic and abiotic selective factors hypothes...

Body size of bison (Bison bison) declines with rising global temperature across the fossil record and rising annual temperatures across the Great Plains, but what are the underlying drivers? Body size depends on growth, which depends on maximizing net energy and nutrient flows for the production of tissues at seasonal scales across the range of the...
Thesis

Large grazers are visible and valuable indicators of the effects of projected changes in temperature and drought on grasslands. The grasslands of the Great Plains have supported the greatest number of bison (Bison bison; Linnaeus, 1758) since prehistoric times. We tested the hypothesis that body mass (BM, kg) and asymptotic body mass (ABM, kg) of B...
