Data from: The weekend intensive

Elliot Isom
Traditionally, counselor education instruction has taken place in the face-to-face format. However, with the shift toward online learning, more counselor education programs are incorporating distance education into the curriculum. This study is an examination of skills acquisition and comparison of students enrolled in introductory counseling skills courses in an online counselor education program. The courses were delivered online with brief face-to-face meetings in two different formats: four consecutive days or two separate weekends. Results indicated...

Quantifying temporal variation in dietary niche to reveal drivers of past population declines; stable isotope, harvest trends, and land use

Amanda Cheeseman, Brian Tanis & Elmer Finck
1. Given the long and dynamic history of anthropogenic disturbances to ecosystems, it is difficult to determine the drivers of past population declines. These uncertainties dilute the efficacy of conservation efforts and might hinder species and ecosystem recovery. 2. Niche quantification can be a useful tool for understanding drivers of past population declines. Niche parameters reflect key resources used, providing insight into the conditions needed to achieve population stability. By reconstructing a population’s niche position...

Data from: Intraspecific variation of a dominant grass and local adaptation in reciprocal garden communities along a US Great Plains’ precipitation gradient: implications for grassland restoration with climate change

Identifying suitable genetic stock for restoration often employs a ‘best guess’ approach. Without adaptive variation studies, restoration may be misguided. We test the extent to which climate in central US grasslands exerts selection pressure on a foundation grass big bluestem (Andropogon gerardii), widely used in restorations, and resulting in local adaptation. We seeded three regional ecotypes of A. gerardii in reciprocal transplant garden communities across 1150 km precipitation gradient. We measured ecological responses over several...

Data from: Ecotypes of an ecologically dominant prairie grass (Andropogon gerardii) exhibit genetic divergence across the U.S. Midwest grasslands environmental gradient

Big bluestem (Andropogon gerardii) is an ecologically dominant grass with wide distribution across the environmental gradient of U.S. Midwest grasslands. This system offers an ideal natural laboratory to study the nature of population divergence and adaptation in spatially varying climates. Objectives were to: (i) characterize neutral genetic diversity and structure within and among three regional ecotypes derived from 11 prairies across the U.S. Midwest environmental gradient, (ii) distinguish between the relative roles of isolation-by-distance (IBD)...

Data from: Adaptive genetic potential and plasticity of trait variation in the foundation prairie grass Andropogon gerardii across the US Great Plains’ climate gradient: Implications for climate change and restoration

Loretta C. Johnson, Matthew Galliart, Sofia Sabates, Hannah Tetreault, Angel DeLaCruz, Johnny Bryant, Jacob Alsdurf, Mary Knapp, Nora Bello, Sara Baer, Brian Maricle, David Gibson, Jesse Poland, Paul St. Amand, Natalie Unruh, Olivia Parrish & Loretta Johnson
Plant response to climate depends on a species’ adaptive potential. To address this, we used reciprocal gardens to detect genetic and environmental plasticity effects on phenotypic variation and combined with genetic analyses. Four reciprocal garden sites were planted with three regional ecotypes of Andropogon gerardii, a dominant Great Plains prairie grass, using dry, mesic, wet ecotypes originating from western KS to Illinois that span 500 to 1,200 mm rainfall year-1. We aimed to answer: (1)...
