Varying Responses to Heat Stress and Salinization Between Benthic and Pelagic Riverine Microbial Communities.

Microbial communities play a crucial role in the functioning of freshwater ecosystems but are continuously threatened by climate change and anthropogenic activities. Elevated temperatures and salinisation are particularly challenging for freshwater habitats, but little is known about how microbial communities respond to the simultaneous exposure to these stressors. Here, we use mesocosm experiments and amplicon sequencing data to investigate the responses of pelagic and benthic microbial communities to temperature and salinity increases, both individually and in combination.

Tire wear particles drive size-dependent loss of freshwater bacterial biofilm diversity.

Tire wear particles (TWPs) represent a significant, yet understudied, source of anthropogenic pollution in aquatic environments, contributing to microplastic contamination and potentially altering microbial ecosystems. As TWPs are continuously released through abrasion during vehicle use, they accumulate in rivers and sediments, where they can act as surfaces for microbial biofilm formation. In this study, we investigated how TWP characteristics - particle size (small & large), wear condition (unused & used), and vehicle type (car & truck) - affect microbial biofilm composition after four weeks of exposure in the River Rhine, compared to natural sediment.

The impact of elevated temperature and salinity on microbial communities and food selectivity in heterotrophic nanoflagellates in the Boye River.

Microbial predator-prey interactions play a crucial role in aquatic food webs. Bacterivorous protists not only regulate the quantity and biomass of bacterial populations but also profoundly influence the structure of bacterial communities. Consequently, alterations in both the quantity and quality of protist bacterivory can influence the overall structure of aquatic food webs.

Risk beyond neutropenia: insights into neutrophil migration from newly diagnosed AML until late after allogeneic stem cell transplantation.

Quantification of neutrophil counts is the most relevant assessment of cellular immunity in clinical practice. Patients with neutropenia are considered at risk and are categorized according to its severity. The incidence of febrile neutropenia varies, but patients with acute myeloid leukemia are traditionally considered at high risk, especially following myelotoxic treatments.
