Tradeoffs between elemental homeostasis and growth govern freshwater phytoplankton responses to salinization

open access: yesLimnology and Oceanography, EarlyView.
Abstract Anthropogenic salinization resulting from road salt application can degrade aquatic environments by altering the structure and function of phytoplankton communities, ultimately reducing flows of resources through aquatic food webs. However, physiological mechanisms underlying taxon‐specific responses to salinization are often poorly linked to ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Population genomic analyses reveal extensive genomic regions within selective sweeps associated with adaptation and demographic history of a wheat fungal pathogen

open access: yesNew Plant Protection, EarlyView.
Applying population genomics, this study revealed that Pst exhibits slower linkage disequilibrium decay compared to rust fungi with known sexual reproduction, identified extensive hard and soft sweeps linked to Pst adaptation, and demonstrated that crop domestication and breeding programs have significantly influenced pathogen population sizes ...
