Lichen bleaching as a response to long‐term experimental warming in the High Arctic

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

The Miners of South America: Impacts of Climate Change on the Distribution of Geositta Miners Along Elevational Gradients

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
We modeled the current and future distributions of seven Geositta species along elevational gradients in South America under two climate change scenarios. Our results show that most species are projected to lose suitable habitats, particularly under the high‐emission scenario, with distinct responses between lowland and highland taxa.

Exploring the Effects of Ultrasound Processing on Food Packaging Laminated With Aluminum Foil

open access: yesPolymer Engineering &Science, Volume 65, Issue 12, Page 7136-7147, December 2025.
ABSTRACT This study investigates the effects of ultrasound (US) processing on laminated plastic packaging containing aluminum foil for food contact applications. Two multilayer structures, PET/Al/PE and PET/Al/PP, were exposed to US at 25 kHz and 8.75 W/L for up to 40 min at 25°C and 60°C, using a 3% acetic acid as a food simulant.

Landscape and crop diversity contributes to greater yield stability

open access: yesJournal of Applied Ecology, Volume 62, Issue 11, Page 3092-3104, November 2025.
These findings underscore the importance of promoting crop diversity and maintaining heterogeneous agricultural landscapes, particularly in pollinator‐dependent crops. Promoting diverse agricultural landscapes with balanced heterogeneity can enhance the resilience of agricultural systems to climate change and contribute to long‐term food security ...
