Halophila stipulacea biomass and density data relating to phytomyxid infection. This dataset is associated with the following publication: Kaldy, J., C. Sullivan, A. Dieppa, I. Cappielo Cosme, M. Orizondo Lugo, and M. Schiebout. First record of Phytomyxid infection of the non-native seagrass Halophila stipulacea in Puerto Rico. BOTANICA MARINA. Walter de Gruyter GmbH, Berlin, GERMANY, bot-2022-0074, (2023).

This data release includes metadata and tabular datasets that document (1) Austropuccina, Ceratocystis and Myrtaceae qPCR (quantitative polymerase chain reaction) DNA detections in Passive Environmental Samplers (PES), (2) wind speed, wind gust speed, and wind direction measurements collected at two sites in the Kahuku Unit of Hawai'i Volcanoes National Park (HAVO) where paired PES were located, (3) localities, sites and elevations where PES were located, and (4) Genbank accession numbers for Austropuccinia and Ceratocystis DNA sequences amplified from samples collected in a subset of PES. These raw data were analyzed and reported in the manuscript "Environmental Monitoring for Invasive Fungal Pathogens of ʽŌhiʽa (Metrosideros polymorpha) on the Island of Hawaiʽi".

Variability in abundance of virus-like particles (VLP), VLP decay rates and prokaryotic mortality due to viral infection were determined in three Antarctic areas: Bellingshausen Sea, Bransfield Strait and Gerlache Strait, during December 1995 and February 1996. VLP abundance showed very small spatial variability in the three areas (7 X 10^6 - 2 X 10^7 VLP/ml). VLP abundance, on the other hand, decreased one order of magnitude from the surface to the bottom, in two stations where deep vertical profiles were sampled. Low seasonal variability in VLP abundance was found when comparing each area separately. Diel VLP variability was also very low. VLP abundance showed the lowest values when solar irradiation was maximal, in two of the three stations where diel cycles were examined. Viral decay rates (VDR) were determined using KCN in two kinds of experiments. Prokaryotic mortality due to viral infection was always higher than that due to bacterivores in the stations where both factors of prokaryotic mortality were measured. Viral infection accounted for all the prokaryotic heterotrophic production in Bellingshausen Sea and Gerlache Strait and for half of the prokaryotic heterotrophic production in Bransfield Strait. These high values of prokaryotic mortality due to viral infection are difficult to reconcile in nature, and more work is necessary to determine the mechanisms involved in the disappearance of viruses.

Campy STICS data. This dataset is associated with the following publication: Lye, D., I. Struewing, T. Gruber, K. Oshima, E. Villegas, and J. Lu. A Gallus gallus Model for Determining Infectivity of Zoonotic Campylobacter. Frontiers in Microbiology. Frontiers, Lausanne, SWITZERLAND, 10: 2292, (2019).

This dataset includes bacterial abundance, cell volume and activity data collected using CTD rosette and bottle sampler. These data were collected aboard Nathaniel B. Palmer during cruises 96-4a (OCT 17-NOV 06, 1996), 97-01 (Jan 14 - Feb 06, 1997), and 97-03 (Apr 12 - 28, 1997), as part of the JGOFS Southern Ocean Project. The principal investigator is Dr. Hugh Ducklow, Virginia Institute of Marine Science.
