Transcriptomic responses of sponge holobionts to in situ, seasonal anoxia and hypoxia

This study examines the transcriptomic responses of two sponge species and their microbial symbionts to seasonal anoxia and hypoxia, revealing species-specific adaptations and limited metabolic changes under low oxygen conditions.

Oxygen production via NO dismutation in different ammonia oxidizers.

The paper investigates oxygen production via NO dismutation in various ammonia oxidizers, finding that multiple AOA and AOB species can produce oxygen and N2 under low-oxygen conditions.

Oxygen production by an ammonia-oxidizing archaeon

This study shows that the ammonia-oxidizing archaeon Nitrosopumilus maritimus produces oxygen and dinitrogen in the dark, challenging previous assumptions about its metabolic role in oxygen-depleted environments.

The effects of seasonal anoxia on the microbial community structure in demosponges in a marine lake (Lough Hyne, Ireland)

This paper investigates how seasonal anoxia affects microbial communities in sponge species in a marine lake, finding that some sponges rely on specific symbionts for anoxic tolerance.

The global explosion of eukaryotic algae: the potential role of phosphorus?

This study investigates whether phosphorus availability influenced the rise of eukaryotic algae by comparing competition between cyanobacteria and algae under different phosphorus conditions.

Very few sites can reshape a phylogenetic tree

The paper shows that removing specific sites from phylogenetic datasets can produce alternative tree topologies, highlighting issues with gene representation and standardization in phylogenetic analysis.
