Food Availability Cannot Explain Dispersal and Settlement Decisions of a Grassland Bird

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We test a commonly assumed explanation for animal movements—namely that food availability shapes where animals disperse to. Based on the results of four strong predictions, 3 years of data, and hundreds of individual birds, we show that food cannot explain breeding dispersal in this system, and we propose alternative explanations consistent with our ...

An injectable subunit vaccine containing Elongation Factor Tu and Heat Shock Protein 70 partially protects American bison from Mycoplasma bovis infection

Frontiers in Veterinary Science
Mycoplasma bovis (M. bovis) is the etiologic agent of high mortality epizootics of chronic respiratory disease in American bison (Bison bison). Despite the severity of the disease, no efficacious commercial vaccines have been licensed for the prevention ...

Unraveling the Evolutionary History of Snow Sheep (Ovis nivicola): Genome‐Wide Single Nucleotide Polymorphism Analysis Reveals Genetic Diversity and Clarifies Taxonomy

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study chronicles all described subspecies of snow sheep (Ovis nivicola) since 1829, reviewing taxonomic assessments by key systematists. Using genome‐wide SNP genotyping on 337 samples from 15 populations, we validate and refine subspecies classifications, revealing eight genetic clusters and proposing a new subspecies (O. n. ernsti).

Fecal glucocorticoid metabolites associated with nutrition in American plains bison

Frontiers in Ecology and Evolution
American plains bison (Bison bison) take advantage of naturally-available nutrients, especially protein, by shifting grazing among cool-season grasses, forbs, legumes, and warm-season grasses as plant species transition from growing to dormant states ...

Soil nutrients and microbial community resistant to patch‐burn grazing in southwestern North Dakota

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Patch‐burn grazing uses the interactive effects of prescribed fire and herbivory to increase heterogeneity in aboveground ecosystem properties. Understanding how management that targets aboveground heterogeneity translates to soil properties and processes provides an important whole‐system context for practitioners.

Cattle and bison grazing decreases monarch egg and larval abundance in the Central United States

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Monarch butterflies have experienced massive population declines and have been proposed to be listed as threatened under the U.S. Endangered Species Act. Milkweeds (Asclepias spp.) are the sole host plant for monarch larvae, and milkweed abundance has dramatically declined in the past 25 years due to increased usage of herbicides and the ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.
