Host-mediated niche construction of bacterial communities in an aquatic microecosystem
Abstract. Microbes coordinate homeostasis in host-associated and environmental ecosystems alike, but the connectivity of these biomes is seldom considered.

Excited to share our new paper out in @isme-microbes.bsky.social. We asked if environmental microbial communities can be adaptively modulated by host species that transiently acquire their symbionts from the environment #SymbioSky #MicrobiomeSky

Viral Dark Matter: Illuminating Protein Function, Ecology, and Biotechnological Promises
Viruses are the most abundant biological entities on Earth and play central roles in shaping microbiomes and influencing ecosystem functions. Yet, most viral genes remain uncharacterized, comprising w...
