Vom Triplett zum Twist: Mechanismus der photochemischen E/Z‐Isomerisierung des Nahinfrarot‐Photoschalters peri‐Anthracenthioindigo

open access: yesAngewandte Chemie, Volume 137, Issue 38, September 15, 2025.
The full photoisomerization mechanism of the all‐red‐light addressable peri‐anthracenethioindigo (PAT) has been decoded. Theory and transient absorption spectroscopy show that both E→Z$E\rightarrow Z$ and Z→E$Z\rightarrow E$ switching proceed via the triplet state.

Host Evaluation: Reliance on Symbionts: A new metric for quantifying nutrient exchange in nutritional mutualisms

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 9, Page 2048-2066, September 2025.
Abstract Mutualisms between autotrophs and heterotrophs that exchange nutrients are of pivotal importance in the ecology and evolution of life on Earth. However, investigation of holobiont trophic strategy (reliance on autotrophy vs. heterotrophy) is hampered by practical challenges in quantifying their diverse nutritional pathways.

What are the effects of sea lice on wild and farmed Pacific and Atlantic salmon? A systematic map protocol

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
This protocol sets out the research methodologies for a systematic map to identify, collate and describe the information that exists on the effects of sea lice from net‐pen salmon farms on wild, enhanced or farmed Pacific (i.e. Chinook, coho, chum, sockeye or pink salmon) and Atlantic salmon globally. The results will help guide further exploration and
