Landscape wetness and beaver wetlands enhance environmental prevalence of Francisella spp.
Ecosphere, Volume 17, Issue 6, June 2026.Abstract Identifying the contributions of biotic and abiotic factors in pathogen transmission is essential to mitigate vector‐borne and zoonotic disease risk. Francisella tularensis is the etiological agent of the infectious disease tularemia in wildlife and humans. Environmental factors driving transmission in wildlife, including the role of hares and

Salted Peat: The Forgotten Casualty of Rising Sea Level in Freshwater Coastal Tropical Peatlands
Global Change Biology Communications, Volume 1, Issue 2, June 2026.This paper invites reflection on the largely overlooked risk that rising sea levels may salinize coastal tropical peatlands, potentially destabilizing vegetation, carbon cycling, and livelihoods. By synthesizing emerging evidence, it highlights a critical blind spot in climate models and adaptation frameworks that warrant urgent scientific and policy ...

The Shrinking Caspian Sea: Eco‐Hydrological Responses to Human and Climate Pressures
Earth's Future, Volume 14, Issue 6, June 2026.Abstract The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood.

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Compound flooding involves the interaction of multiple flood processes (e.g., coastal, fluvial, and pluvial) and is modulated by several factors (e.g., weather, climate, topobathy, morphology, time‐lag). In tropical and subtropical regions globally, Tropical Cyclones (TCs) are a primary cause of compound flooding as they generate substantial ...
