Ciliate-generated advective seawater transport supplies chemoautotrophic ectosymbionts
Vopel, K; Pohn, M; Sorgo, A; Ott, J (Inter-Research, 2001)Variations of [O2] and [H2S] in seawater surrounding laboratory reared sessile ciliates with ectosymbiotic chemoautotrophic bacteria were studied at high spatial and temporal resolutions using amperometric microsensors. ... -
Microclimate of the brown alga Feldmannia caespitula interstitium under zero-flow conditions
Pohn, M; Vopel, K; Grunberger, E; Ott, J (Inter Research, 2001)The microclimate of the brown alga Feldmannia caespitula (J. Agardh) Knoepffler-Peguy interstitium was studied using microelectrode techniques. Zero water flow and irradiances of 170 and 1500 mu mol photons m(-2) s(-1) ... -
Wave-induced H2S flux sustains a chemoautotrophic symbiosis
Vopel, K; Thistle, D; Ott, J; Bright, M; Roy, H (American Society of Limnology and Oceanography (ASLO), 2005)Symbioses involving sulfur-oxidizing bacteria and invertebrate hosts require a source of reduced sulfur, a source of O-2, and transport mechanisms that ensure them a supply of both. We investigated these mechanisms using ...
