Sound emissions from human activities represent a pervasive environmental stressor. Individual responses in terms of behaviour, physiology or anatomy are well documented but whether they propagate through nested ecological interactions to alter complex communities needs to be better understood. This is even more relevant for freshwater ecosystems that harbour a disproportionate fraction of biodiversity but receive less attention than marine and terrestrial systems.

We evaluate the diversity of soft rot (SRP) of the genera and over 2 years in a temperate, mixed-use watershed. The abundance of isolated strains correlates with the agricultural gradient along the watershed with a positive correlation found with temperature, nitrate, and dissolved organic carbon water concentration.

We report here, for the first time, changes in gene expression induced by variations in pH/pCO in the widespread and abundant coccolithophore . Batch cultures were subjected to increased partial pressure of CO (pCO; i.
