“…Following Nival et al (1975) Ammonium and phosphorus excretion rates were estimated for each taxa and station from the multivariate regression equations by Ikeda (1985) in which independent variables are animal body weight (carbon) and temperature. The daily NH 4 and PO 4 excretion values by total zooplankton equal the sum of values for all taxa.…”

Abstract.This paper presents new results on spatial and temporal distribution patterns of mesozooplankton in the western 20 tropical South Pacific along the 20°S south visited during austral summer (February -April 2015). By contributing to the interdisciplinary OUTPACE (Oligotrophy to UlTra-oligotrophy PACific Experiment) project (Moutin et al., 2017), the specific aims of this study dedicated to mesozooplankton observations were (1) to document zooplankton density, species diversity, and biomass along the transect, and (2) to characterize the trophic pathways from primary production to mesozooplankton . Along a West-East transect of 4000 km from New Caledonia to the French Polynesia, 15 short-duration 25 stations (SD-1 to SD-15, 8hours each) dedicated to a large-scale description, and three long-duration stations (LD-A to LD-C, 5days each), respectively positioned (1) in offshore northern waters of New Caledonia, (2) near Niue Island, and (3) in the subtropical Pacific gyre near the Cook Islands, were sampled with a Bongo Net with 120 μm mesh size net for quantifying mesozooplankton abundance, biomass, community taxonomy and size structure, and size fractionated content of δ Daily grazing pressure on phytoplankton stocks and daily regeneration by zooplankton were as well estimated for the different regions showing contrasted impacts between MA and GY regions. For the 3 LD stations, it was not possible to find any relationship between the abundance and biomass in the water column and swimmers found in sediment traps. Diel vertical migration of zooplankton, which obviously occurs from observed differences in day and night samples, might 25 strongly influence the community of swimmers in traps.Biogeosciences Discuss., https://doi

Abstract:The role of the heterotrophic dinoflagellate Noctiluca scintillans in affecting the nutrient-environment and aquatic ecosystem was investigated in the neritic area of Sagami Bay, Kanagawa, Japan, from January 2002 to December 2006, based on abundance, intracellular nutrient content, excretion rate and response of phytoplankton (diatoms) to enrichment of nutrients extracted from N. scintillans cells. Seasonal variations in abundance and vertical distribution of N. scintillans were significantly related to the physical structure of the water column, water temperature, chlorophyll a and primary productivity. Intracellular nutrient contents, except for Si(OH) 4 -Si, revealed clear seasonal fluctuations, which were significantly correlated to cell size variations. Thalassiosira rotula increased to higher cell abundances at higher concentrations of nutrients, which were extracted from N. scintillans cells. NH 4 + -N and PO 4 3--P excretion rates were much higher during the first 1-3 h, and decreased rapidly with time. Daily NH 4 + -N and PO 4 3--P supply by N. scintillans excretion was estimated to be on average 34.8% and 55.3%, especially 50.6-85.4% and 80.5-135.8% in April-July (monthly mean), of the daily N and P requirement for primary production, respectively. The large amounts of nutrients regenerated and released by N. scintillans excretion can increase the N and P concentrations in ambient seawater, especially in the upper layer in spring-summer, and consequently affect phytoplankton (diatom) abundance. These may exacerbate eutrophication in these waters by a mutually supportive relationship between phytoplankton and N. scintillans: bottom-up control (phytoplankton-N. scintillans) and nutrient supply by N. scintillans to phytoplankton through excretion.

“…Obviously, the exponential relation between temperature and metabolism (e.g. Robinson et al, 1983;Ikeda, 1985), is reflected not only on the level of population P/B ratios (e.g. Tumbiolo and Downing, 1994;, but also in community P/B ratios.…”

Production and productivity (P/B ratio) of the high Antarctic Weddell Sea and Lazarev Sea macrozoobenthos are estimated by an empirical multiple non-linear model (artificial neural network) based on biomass data and other biotic and abiotic parameters. Average community (1500-4300 m). Community P/B ratio increases with depth from 0.18 year to 0.55 year . Taking into account the effects of water depth on production and of temperature on P/B ratio, Antarctic communities show no evidence of unique characteristics with respect to overall energy flow.
