Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

People and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Individual Uncertainty and Policy Compliance During the COVID‐19 Pandemic

Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Ample scholarship examines the extent to which public policies in representative democracies reflect the priorities and needs of the public, often finding that individuals are unaware of many policy issues and policy responses. This may be especially true when issues of risk and scientific uncertainty are involved, which can be difficult for ...

Preconditioning of Local Convective Initiation in Central Europe by Land–Atmosphere Coupling: Heated Condensation Framework Diagnostics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract This study investigates the role of land‐atmosphere coupling in favorable conditions for locally triggered convection in central Europe. The region is in so‐called transitional zones located between wet and dry climates, which favor land‐atmosphere coupling in summer.
