Ecology and Evolution, 2018 Grazing‐induced changes in plant quality have been suggested to drive the negative delayed density dependence exhibited by many herbivore species, but little field evidence exists to support this hypothesis. We tested a key premise of the hypothesis that

Animal Conservation, EarlyView.Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Neurobiology of DiseasePrion disease phenotypes (prion strains) are primarily determined by the specific misfolded conformation of the cellular prion protein (PrPC). However, post-translational modifications, including glycosyl phosphatidyl inositol (GPI) membrane anchoring ...

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability
Andrology, EarlyView.ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

The endpoint multilinear Kakeya theorem via the Borsuk--Ulam theorem [PDF]
, 2012 We give an essentially self-contained proof of Guth's recent endpoint multilinear Kakeya theorem which avoids the use of somewhat sophisticated algebraic topology, and which instead appeals to the Borsuk-Ulam ...

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe
Archaeometry, EarlyView.ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Rapid generation of prion disease models using AAV‐delivered PrP variants in knockout mice
Brain Pathology, Volume 36, Issue 4, July 2026.We developed a rapid AAV‐based system to generate prion disease models in weeks rather than months. Following systemic AAV9P31 delivery of modified PrP to knockout mice, we achieved brain‐wide expression and successful propagation of both classical (RML) and atypical (GSS‐A117V) prion strains.
