Bacterioplankton communities reveal horizontal and vertical influence of an Island Mass Effect Open
Summary Coral reefs are highly productive ecosystems with distinct biogeochemistry and biology nestled within unproductive oligotrophic gyres. Coral reef islands have often been associated with a nearshore enhancement in phytoplankton, a p…

Giant kelp microbiome altered in the presence of epiphytes Open
Characterizing patterns in the microbial communities associated with canopy‐forming kelps is critical to understanding the mechanisms shaping macroalgal microbiomes. Using 16S rRNA gene sequencing, we characterized bacterial and archaeal c…
An Island Mass Effect Resolved Near Mo’orea, French Polynesia Open
We sought to resolve the extent, variability, and magnitude of productivity enrichment around a high tropical island consistent with the phenomenon of an Island Mass Effect (IME). Key biogeochemical constituents and physical oceanographic …

Parasitic nematodes of marine fishes from Palmyra Atoll, East Indo-Pacific, including a new species of Spinitectus (Nematoda, Cystidicolidae) Open
Here, we present the results of a taxonomic survey of the nematodes parasitizing fishes from the lagoon flats of Palmyra Atoll, Eastern Indo-Pacific. We performed quantitative parasitological surveys of 653 individual fish from each of the…

Parasitic copepods (Crustacea, Hexanauplia) on fishes from the lagoon flats of Palmyra Atoll, Central Pacific Open
We surveyed copepods parasitic on the fishes at Palmyra, a remote atoll in the Central Indo-Pacific faunal region. In total, we collected 849 individual fish, representing 44 species, from the intertidal lagoon flats at Palmyra and recover…
Elevated <i>p</i> CO <sub>2</sub> alters marine heterotrophic bacterial community composition and metabolic potential in response to a pulse of phytoplankton organic matter Open
Summary Factors that affect the respiration of organic carbon by marine bacteria can alter the extent to which the oceans act as a sink of atmospheric carbon dioxide. We designed seawater dilution experiments to assess the effect of p CO 2…

Monogenea of fishes from the lagoon flats of Palmyra Atoll in the Central Pacific Open
A survey of the monogeneans of fishes from the lagoon flats of Palmyra Atoll detected 16 species already reported from the Indo-West Pacific faunal region. A total of 653 individual fish from 44 species were collected from the sand flats b…
Elevated pCO2 enhances bacterioplankton removal of organic carbon Open
Factors that affect the removal of organic carbon by heterotrophic bacterioplankton can impact the rate and magnitude of organic carbon loss in the ocean through the conversion of a portion of consumed organic carbon to CO2. Through enhanc…
The Effects of pCO2 on Bacterioplankton-Mediated Carbon Cycling Open
The concentration of atmospheric carbon dioxide (CO2) is increasing at extraordinary rates (e.g. Le Quéré et al. 2016). Effectively mitigating the impacts of increasing atmospheric CO2 on climate change, the ocean has absorbed roughly 30 %…
