Explanation of Boundary Layer Oxygen Diffusion Limitation Hypothesis for Sea Star Wasting

Ian Hewson, Department of Microbiology, Cornell University **I was asked recently to put together a non-oceanographer/scientist explanation of sea star wasting and our recent work on boundary layer oxygen diffusion limitation, which is below** Seven years into our investigation of sea star wasting, we have learned much about starfish, their biology, and how they interact… Read More Explanation of Boundary Layer Oxygen Diffusion Limitation Hypothesis for Sea Star Wasting

New Preprint on Sea Star Wasting – It’s all about the Boundary Layer

After many years of concerted investigation, the team and some colleagues now have multiple, convergent lines of evidence to suggest that sea star wasting disease is a sequela of organic matter remineralization (and subsequent hypoxic conditions) in the boundary layer overlying respiratory surfaces. We see this reflected in microbiome trends during wasting (copiotrophs –> anaerobes).… Read More New Preprint on Sea Star Wasting – It’s all about the Boundary Layer

Mini-Review on Marine Coronaviruses

Gideon Mordecai (UBC) and I have recently published a mini-review on marine coronaviruses in the journal Frontiers in Microbiology. While not much is known about the true diversity of coronaviruses in marine ecosystems (because they are hugely under-sampled), we can learn about how they may behave in marine habitats through other enveloped, ssRNA viruses.

Postdoc Fellowship!

Any postdocs want to come and work with me? Here’s a great opportunity for funding from the Simons Foundation: https://www.simonsfoundation.org/grant/simons-postdoctoral-fellowships-in-marine-microbial-ecology/ Broadly, any projects should be focused around microbial ecology – so probably NOT projects related to disease pathobiology. Ideas for viable projects include: Virus-zooplankton interactions; Viral-biofoulant (e.g. barnacles, tunicates, etc) interactions; Microbiology of metazoan diseases;… Read More Postdoc Fellowship!
