Acclimation of Charophytes to Spectral Composition of Light at Limiting Irradiances

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Irradiance is regarded as a key factor determining the maximum colonization depth (Z0) of submerged macrophytes. However, the relevance of acclimation capabilities to spectral composition under such low‐light conditions remains poorly understood.

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, Volume 2026, Issue 6, June 2026.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Influence of VOCs on the auto-ignition of Mediterranean plants

Journal of Physics: Conference Series
Abstract In view of the increasing frequency of extreme fires, this work proposes to identify the compounds that promote the auto-ignition of plants and thus the spread of wildfires. The objective is to better understand the biochemical and thermochemical aspects of wildfire propagation in order to better anticipate extreme fires such as

Insurance and the “Irrationalization” of Disaster Policy: A Political Crisis Theory for an Age of Climate Risk

The British Journal of Sociology, Volume 77, Issue 3, Page 482-495, June 2026.
ABSTRACT In the last several years, disaster insurance programs around the world have experienced disruptions that many observers interpret to be a primary symptom of “climate crisis” (Bittle 2024). Governments have responded to these disruptions through disjointed and at times contradictory measures: they treat disasters, alternately, as “Acts of God”

Leveraging Roadless Areas to Support Strict Protection in the EU

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Strictly protected areas exhibit lower levels of disturbance to habitats and species and are central to biodiversity conservation. Yet only 4% of the EU's land is currently placed under strict protection, far below the 10% target set by the EU Biodiversity Strategy for 2030. This study examines the potential of roadless areas to contribute

Milestones, revisited: Iterative and nonlinear identity development in Gen‐Z

Journal of Research on Adolescence, Volume 36, Issue 2, June 2026.
Abstract This study examined how sexual and gender identity development experiences, commonly operationalized as “milestones,” were navigated by Gen‐Z LGBTQ+ young people. Using a life‐history calendar approach, milestone‐related experiences were treated as heuristic sites of meaning‐making rather than fixed developmental benchmarks.
