Initial Recovery of the Herbaceous Layer of a Temperate Deciduous Forest After 30 Years of Nitrogen Amendments: Implications for the Success of the Clean Air Act

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Equity in Evacuation Planning and Mitigation: Implications of Transportation Infrastructure and Social Vulnerability

open access: yesGrowth and Change, Volume 57, Issue 2, June 2026.
ABSTRACT This research addresses a critical but underexamined challenge in disaster preparedness: the identification of neighborhoods where evacuation is hardest to accomplish based on physical infrastructure constraints as well as inherent social vulnerability. Existing evacuation approaches emphasize the flow of traffic and the capacity of roads, but

“A Whale of a Chance”: Thomas E. Dewey, the U.S. South, and the Election of 1948

open access: yesPresidential Studies Quarterly, Volume 56, Issue 2, June 2026.

Dissolved Organic Matter and Pretreatment Effects on PFAS Removal by Granular Activated Carbon

open access: yesAWWA Water Science, Volume 8, Issue 3, May/June 2026.
ABSTRACT Granular activated carbon (GAC) adsorption is commonly used to remove per‐ and polyfluoroalkyl substances (PFAS) from water. In this study, we evaluated the impact of dissolved organic matter (DOM) concentration and pretreatment on GAC use rates for PFAS removal.

Dog attacks on wild desert tortoises: A risk model

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

A scalable integrated population model for estimating abundance for gamebird management

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our O‐IPM presents an efficient and practical approach for estimating wildlife population demographics, particularly in situations where data collection is limited. This study demonstrates how information from intensive, localized research can be leveraged to inform broader‐scale management through strategic use of prior information.
