Can't outrun recurrence: Long‐term outcomes of treating American black bear sarcoptic mange

open access: yesThe Journal of Wildlife Management, EarlyView.
Abstract The growing incidence of sarcoptic mange in American black bears (Ursus americanus) has become a concern for wildlife managers in the eastern United States. Inconsistency in the use of single and multi‐dose treatment approaches makes it difficult to evaluate their effects on post‐release outcomes of mange‐rehabilitated bears, which remain ...

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

open access: yesOikos, EarlyView.
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.

Blackberry Propagation Limitations When Using Floricane Cuttings

open access: yesHortTechnology, 2019
Outdoor production of floricane-fruiting (FF) blackberry (Rubus subgenus Rubus) is problematic in the Northern Great Plains region of the United States because cane injury and plant death will occur from exposure to temperatures −15 °C and colder.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

open access: yesJournal of Polymer Science, EarlyView.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...
