Different relationships were found between physiological structure and bottom-up variables, with HNA bacteria apparently more responsive to phytoplankton only during the bloom, coinciding with larger average cell sizes of LNA bacteria.Moderate phytoplankton-bacterioplankton coupling of biomass and activity was only observed in the bloom and post-bloom phases, while relationships between both compartments were not significant under stratification. With all data pooled, bacteria were only weakly bottom-up controlled. Our analyses show that the biomass and 3 production of planktonic algae and bacteria followed opposite paths in the transition from bloom to oligotrophic conditions.

Nutrient supply controls picoplankton community structure during three contrasting seasons in the northwestern Mediterranean Sea

“…It is remarkable that LNA (0.054 ± 0.003 µm 3 ) were larger than HNA (0.045 ± 0.003 µm 3 ) bacteria during F1 (Table 2) (Gomes et al 2015), whereas the opposite trend, frequently observed in temperate waters (Calvo-Díaz & Morán 2006), was observed during F2 and F3. LNA bacteria were larger during F1 compared to F2, whereas the opposite trend was found for HNA bacteria.…”

“…Two aliquots from the same sample were used for the study of picophytoplankton (0.6 ml) and heterotrophic bacteria (0.4 ml), analyzed at high (∼mean 52 µl min for picoeukaryotes (Worden et al 2004). More details about the processing and analysis of flow cytometry samples are provided in Gomes et al (2015).…”

Impact of grazing, resource availability and light on prokaryotic growth and diversity in the oligotrophic surface global ocean

“…Data were inspected in a green fluorescence (FL1) versus light side scatter (SSC) plot and analysed as detailed as in Gomes et al (2015). Samples of 1.2 ml seawater were fixed with a paraformaldehyde-glutaraldehyde mix (1% and 0.05% final concentrations respectively) and stored at −80 C until analysis in the laboratory within a maximum of 7 months after the end of the cruise.…”

Distribution Dynamic of Heterotrophic Bacteria in Jakarta Bay

“…Hal ini sesuai dengan penelitian yang dilakukan Karrasch et al (2001), Pearce et al (2011), dan Gomes et al (2015) lurus dengan banyaknya fitoplankton yang mengalami blooming. Ruyitno (2007) dalam penelitiannya di perairan Kalimantan Timur menemukan adanya keterkaitan antara distribusi bakteri dengan konsentrasi klorofil-a yang menunjukkan adanya hubungan antara kelimpahan fitoplankton dengan bakteri heterotrofik.…”
