The making of novel ecosystems: A process‐based framework for measurement, analysis and application

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

Selective Formation of Pd‐DNA Hybrids Using Tailored Palladium‐Mediated Base Pairs: Towards Heteroleptic Pd‐DNA Systems

open access: yesAngewandte Chemie, Volume 136, Issue 11, March 11, 2024.
The selective creation of Pd‐DNA supramolecular structures using the [Pd(Aqa)] complex (Aqa=8‐amino‐4‐ hydroxyquinoline‐2‐carboxylic acid) highlights its enhanced affinity for cytosine compared to the previously reported [Pd(Cheld)] (Cheld=chelidamic acid).

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Changes in community composition and functional diversity of European bats under climate change

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Climate change is predicted to drive geographical range shifts that will result in changes in species diversity and functional composition and have potential repercussions for ecosystem functioning. However, the effect of these changes on species composition and functional diversity (FD) remains unclear, especially for mammals, specifically ...
