Our takeaway: if we want to understand forest soils, we need to look beyond fungi. Metatranscriptomics reveal important players that PCR-based approaches miss. Really happy to share our new article: Protistan Predators Outshine Fungi in Forest Soil Activity. #ProtistsOnSky #MicrobialEcology #Soil

Chapter 3 of my thesis is now available as a preprint in @biorxiv-ecology.bsky.social We compared 3+ years of coastal microbial time-series from an equatorial site (EAMO, 6°S) and a temperate site (BBMO, 41°N). Our work reinforces the need for observatories across latitudes to track ocean change.

Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long-term microbial ob...

New research suggests that a tiny phytoplankton that is an essential part of the marine food web may decline sharply as oceans warm.
