Using a Brief Body Sway Assessment Device to Track Balance Differences across the Huntington's Disease Integrated Staging System Spectrum

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a mutation in the huntingtin gene on chromosome 4, leading to progressive cognitive decline, motor impairment, and functional disability. Although balance impairment is recognized in HD, its onset and evolution with disease stage remain poorly ...

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

open access: yesOikos, EarlyView.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.
