Pulsed boundary layer flow versus tide-driven deep pore-water flow--What drives sulfide vents in oceanic mangrove peat habitats?

Vopel, K; Roy, H (National Museum of Natural History, Smithsonian Institution, 2009)
Sulfide assimilation by ectosymbionts of the sessile ciliate, Zoothamnium niveum

Roy, H; Vopel, K; Huettel, M; Jorgensen, BB (Springer, 2009)

We investigated the constraints on sulfide uptake by bacterial ectosymbionts on the marine peritrich ciliate Zoothamnium niveum by a combination of experimental and numerical methods. Protists with symbionts were collected ...
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 ...
