Substrate availability may limit the response of tropical bacterioplankton biomass to warming

Limnology and Oceanography, Volume 69, Issue 9, Page 2043-2056, September 2024.
Abstract The response of heterotrophic bacterioplankton to the addition of macrophytic dissolved organic matter (DOM) and temperature was investigated in the Red Sea. We added 40 μmol C L−1 of leachates obtained from seagrass and mangrove leaves to natural bacterial communities, incubated them at three temperatures (25.5°C found in situ plus 3°C below ...
