“…Zooplankton are an essential component of aquatic food webs, creating a crucial link between primary producers and higher trophic level consumers. [1][2][3] Zooplankton provide a rich and abundant source of lipids, the densest form of molecular energy available in marine ecosystems. 4,5 On average, lipids yield greater than two-thirds more energy (per gram) than either carbohydrates or proteins, making them the ideal energy storage molecule for zooplankton.…”

“…The sulfo-phospho-vanillin (SPV) reaction is a popular method for determining total lipids in a variety of sample types: human serum, meibum, microalgae, mosquitos, sh, and more. 19,[27][28][29][30][31][32] The reaction is performed in two steps: (1) treatment of lipids with concentrated sulfuric acid and heat to create carbocation chromogen intermediates, and (2) reaction of those intermediates with vanillin in the presence of phosphoric acid to generate a pink chromophore. The reaction mechanisms are complex and are reported in detail by McMahon et al 28 Herein, we analyze the performance of the SPV assay for measuring the total lipid content (% of wet weight) of various large crustacean zooplankton common to the Arctic and North Pacic oceans in an inter-laboratory comparison study.…”

“…Elevating temperatures are also shifting the whole plankton community towards smaller size, starting from phytoplankton and reaching to species-level decrease in the body size of adult copepods (Daufresne et al, 2009;Garzke et al, 2016). Cascading effects of changing zooplankton composition and the abundance of copepods on fish stocks are well acknowledged in the literature (Lomartire et al, 2021), and these effects have also been related to temperature and salinity changes in the Baltic Sea (Möllmann et al, 2008). Moreover, the importance of body size and the abundance of larger zooplankton taxa, such as copepods, are highlighted by size selectivity of some planktivorous fishes (Lehtiniemi et al, 2007).…”

Combined effect of salinity and temperature on copepod reproduction and oxidative stress in brackish-water environment

et al. 2022

Climate-induced warming and increased river inflows are forcing the Baltic Sea to radical changes in the near future; organisms living in this brackish-water ecosystem are already experiencing osmotic stress, which, together with thermal stress, may have severe consequences on the ecosystem. The aim of this work was to study the combined effect of decreasing salinity and increasing temperature on reproductive success and oxidative stress in zooplankton by using a calanoid copepod Acartia sp. as a model organism. The field study was conducted during summer 2020 in the western Gulf of Finland, using three sampling sites with naturally differing salinity levels. Additionally, the copepods from these sites were experimentally exposed to ambient or 3°C elevated temperature for 72 h. The copepods derived from the deepest and the most saline sampling site suffered less oxidative damage and exhibited relatively high reproduction, while the temperature treatment itself had little effect. On the other hand, the field-based monitoring data showed otherwise; temperature increased lipid peroxidation, glutathione-s-transferase activity, or both in all three sampling sites. Meanwhile, egg production rate was negatively associated with temperature in the area with the lowest salinity. Moreover, egg production rate decreased from June to September along with increasing temperatures in the mid-salinity sampling site, while similar change occurred also in the highest-salinity site between August and September. The combined effect of salinity and sampling date on reproduction indicates the importance of even subtle salinity changes on copepods. Moreover, the data suggest that the unusually strong heatwave was responsible for increased oxidative stress during the sampling season and possibly forced a trade-off between antioxidant activity and reproductive effort.

“…Zooplankton link primary producers and higher trophic levels and so play a key role in ecosystem functioning through the cycling of carbon and nutrients in the water column and subsequent export to benthic communities (Piepenburg et al 1997;Mayor et al 2020;Tarrant 2020;Lomatire et al 2021). Zooplankton species may position themselves on a fine scale in the water column to occupy optimal habitat spaces near the peak of their food resource (Herman 1983;Norrbin et al 2009;Basedow et al 2010) but often without directly matching their prey distribution (Greer et al 2013).…”

Spatial occurrence and abundance of marine zooplankton in Northeast Greenland

We present a large-scale survey of mesozooplankton (size range 0.2–20 mm) across coastal, shelf, and slope locations in Northeast Greenland (latitudes 74–79° N, August 2015 and September 2017). Our study is centred on the Video Plankton Recorder (VPR) for non-invasive in situ observations of taxa distribution and abundance while simultaneously recording oceanographic profiles. A modified WP-2 plankton net (85-μm mesh size) was used primarily not only to verify taxa detected by the VPR but also to make a preliminary comparison of abundance estimates by the two gears. A total of 35 zooplankton taxa were identified with 10 genera alone among copepods (Hexanauplia). Selected taxa from the VPR (N=16) were associated with the temperature-salinity spaces and the chlorophyll a-depth profiles in the study area. From surface to > 900 m depth, the overall temperature and salinity ranged between −1.9 and 6.8 °C and 26.6 and 35.3, respectively. Two copepod genera dominated, i.e. Pseudocalanus prevailed in the upper sub-zero layers in coastal waters whereas Calanus was omnipresent, but mainly abundant in the warmer Atlantic waters at the shelf break. Chlorophyll a levels were in general very low (< 2 mg m-3) and peaked at 30–50 m depth, suggesting post-bloom conditions. Overall, zooplankton abundances tended to increase from the coast towards the slope (9–344×103 individuals m-2). Biodiversity in terms of taxon richness, on the other hand, showed the opposite trend and decreased from 16 taxa at the coast to 5 taxa further offshore.
