Trophic Structure and the Isotopic Niche Dynamics of the Tasiujaq (Eclipse Sound, Nunavut, Canada) Marine Food Web

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 9, September 2025.
ABSTRACT Rapid warming in the Arctic is causing cumulative impacts on ecosystems, including widespread reduction in sea ice extent, resulting in shifts in primary production, which can have cascading bottom‐up trophic influences on marine food web structure and function. Understanding trophic interactions and the structure of local food webs across the

Balancing Doses of EL222 and Light Improves Optogenetic Induction of Protein Production in Komagataella phaffii

open access: yesBiotechnology and Bioengineering, Volume 122, Issue 9, Page 2478-2498, September 2025.
ABSTRACT Komagataella phaffii, also known as Pichia pastoris, is a powerful host for recombinant protein production, in part due to its exceptionally strong and tightly controlled PAOX1 promoter. Most K. phaffii bioprocesses for recombinant protein production rely on PAOX1 to achieve dynamic control in two‐phase processes.

Stochasticity Shapes Microbial Communities in High‐Altitude Lakes, Whereas Species Selection and Homogenization Dispersal Are More Important in Lowland Lakes: Case of Benthic Diatoms in Alpine Lakes

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Lakes microalgal communities are shaped by differing ecological processes depending on their altitude. Based on benthic samples of biofilms analyzed with metabarcoding in several European countries around the Alps, we showed that high‐altitude lake communities are driven by stochastic processes, whereas in lowlands they are driven by homogenizing ...

Ion Source Complementarity for Characterization of Complex Organic Mixtures Using Fourier Transform Mass Spectrometry: A Review

open access: yesMass Spectrometry Reviews, Volume 44, Issue 5, Page 808-829, September/October 2025.
ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.
