Lifestyle modulates riverbed diazotrophy: from abundance and activity to diversity of free-living and biofilm-associated N2 fixers

Rand Lander, Carla Villamarin, Hagar Siebner, Shai Arnon, Edo Bar‐Zeev

This study quantifies N2 fixation rates, diazotroph abundance, and diversity in the hyporheic zone, showing biofilm-associated diazotrophs are more active and abundant than free-living ones.

Heterotrophic diazotrophy along a river to lake continuum: lifestyle and contribution to N2 fixation

Eyal Geisler, Hagar Siebner, Max Kolton, Guy Sisma‐Ventura, Eyal Rahav, Shai Arnon, Edo Bar‐Zeev

This study quantifies the contribution of heterotrophic diazotrophs to N2 fixation in a river-lake continuum, showing their dynamic lifestyles and significant role in nitrogen cycling.
