• Publication: Diverse and temporally-variable particle-associated microbial communities are insensitive to bulk seawater environmental parameters

  There is a growing recognition of marine microenvironments’ roles as reservoirs of biodiversity, sites of enhanced biological activity and in facilitating biological interactions. Here, we examine the bacterial community inhabiting free-living and particle-associated seawater microenvironments at the Pivers Island Coastal Observatory (PICO). 16S rRNA gene libraries from monthly samples (July 2013-August 2014) were used to…

• Publication: Selective feeding by the giant barrel sponge enhances foraging efficiency

  Foraging theory predicts the evolution of feeding behaviors that increase consumer fitness. Sponges were among the earliest metazoans on earth and developed a unique filter-feeding mechanism that does not rely on a nervous system. Once thought indiscriminate, sponges are now known to selectively consume picoplankton, but it is unclear whether this confers any benefit. Additionally,…

• Publication: Diel regulation of hydrogen peroxide defenses by open ocean microbial communities

  Diel regulation of hydrogen peroxide defenses by open ocean microbial communities Hydrogen peroxide (HOOH) is omnipresent in natural waters. Given that sunlight is the primary source of HOOH, we investigated the relationship between time of day and microbial HOOH degradation. Genes encoding HOOH-degrading enzymes were significantly more abundant during the day in ocean metatranscriptomes. While…
