Climate change impacts on California's foundational trees: Demographic shifts are already underway

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract Climate change is a leading threat to global biodiversity. Research on climate change impacts on foundational species, which underlie the structure and function of ecosystems, is critical to developing effective conservation responses. To better understand the landscape of existing research and identify research needs, we conducted a scoping ...

Structural color in Junonia butterflies evolves by tuning scale lamina thickness

open access: yeseLife, 2020
In diverse organisms, nanostructures that coherently scatter light create structural color, but how such structures are built remains mysterious. We investigate the evolution and genetic regulation of butterfly scale laminae, which are simple photonic ...

Mammal Community Responses to Increasing Puma Activity in a Suburban Preserve

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using nine years of camera‐trap data from a suburban preserve, we found preliminary, convergent evidence that increasing puma activity coincided with changes in black‐tailed deer, bobcat and coyote activity. Evidence for changes in brush rabbit and grey fox activity, as well as woody plant density, is more tentative and warrants further study, but ...

Ionospheric Vertical Plasma Drifts Over South America: Long‐Term Multi‐Instrument Observations and TIEGCM and WACCM‐X Evaluations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present the first comprehensive multi‐instrument climatological study of quiet‐time equatorial F‐region vertical plasma drifts across South America, a region where the magnetic declination angle varies significantly. Our analysis of well‐established long‐term ground‐based data sets from the Jicamarca incoherent scatter radar spanning 1968 ...

Improved injection needles facilitate germline transformation of the buckeye butterfly Junonia coenia

open access: yesBioTechniques, 2014
Germline transformation with transposon vectors is an important tool for insect genetics, but progress in developing transformation protocols for butterflies has been limited by high post-injection ova mortality.

Presumption of Patent Validity and Litigation Incentives

open access: yesJournal of Public Economic Theory, Volume 28, Issue 3, June 2026.
ABSTRACT We analyze the effects of the presumption of patent validity on litigation incentives and outcomes. We develop a litigation game between a patent holder and an alleged infringing firm. A court resolves the dispute if there is a trial. We model the court's decision‐making as a learning process based on evidence and consider the presumption as a
