“…A potential reason could be the thermophilic nature of many of the taxa identified in the anticyclone, including the larvae of a Red Sea Lessepsian invader, Nerita sanguinolenta. An adult individual of this species was recently recorded on the Israeli Mediterranean coast for the first time (Rabi et al, 2020). Mesoscale and sub-mesoscale structures can promote introductions of invasive species or recruitment of harmful species, such as the destructive crown-of-thorns starfish (Miller et al, 2015), the extremely venomous box jellyfish Irukandji (Gershwin et al, 2013) and a sea urchin overgrazing the kelp forests (Ling and Johnson, 2009).…”

Abstract. Planktonic food webs were studied contemporaneously in a mesoscale cyclonic (upwelling, ∼ 13 months old) and an anticyclonic (downwelling, ∼ 2 months old) eddy as well as in an uninfluenced background situation in the oligotrophic southeastern Mediterranean Sea (SEMS) during late summer 2018. We show that integrated nutrient concentrations were higher in the cyclone compared to the anticyclone or the background stations by 2–13-fold. Concurrently, Synechococcus and Prochlorococcus were the dominant autotrophs abundance-wise in the oligotrophic anticyclone (∼ 300 × 1010 cells m−2). In the cyclone, functional groups such as dinoflagellates, Prymnesiophyceae and Ochrophyta contributed substantially to the total phytoplankton abundance (∼ 14 × 1010 cells m−2), which was ∼ 65 % lower at the anticyclone and background stations (∼ 5 × 1010 cells m−2). Primary production was highest in the cyclonic eddy (191 mgCm-2d-1) and 2–5-fold lower outside the eddy area. Heterotrophic prokaryotic cell-specific activity was highest in the cyclone (∼ 10 fgCcell-1d-1), while the least productive cells were found in the anticyclone (4 fgCcell-1d-1). Total zooplankton biomass in the upper 300 m was 10-fold higher in the cyclone compared with the anticyclone or background stations (1337 vs. 112–133 mg C m−2, respectively). Copepod diversity was much higher in the cyclone (44 species), compared to the anticyclone (6 small-size species). Our results highlight that cyclonic and anticyclonic eddies show significantly different community structure and food-web dynamics in oligotrophic environments, with cyclones representing productive oases in the marine desert of the SEMS.

“…An exception to the higher species diversity within the cyclone was the gastropods that showed higher diversity in the anti-cyclone station. A potential reason could be the thermophilic nature of many of the taxa identified in the anti-cyclone, first time (Rabi et al, 2020). Mesoscale and sub-mesoscale structures can promote introductions of invasive species or recruitment of harmful species, such as the destructive crown-of-thorn starfish (Miller et al, 2015), the extremely venomous box jellyfish Irukandji (Gershwin et al, 2013), and a sea urchin overgrazing the kelp forests 810 (Ling and Johnson, 2009).…”

Abstract. Planktonic food-webs were studied contemporaneously in a mesoscale cyclonic (upwelling, ~13 months old) and an anti-cyclonic (down-welling, ~2 months old) eddies, as well as in an uninfluenced-background situation in the oligotrophic southeastern Mediterranean Sea (SEMS) during late summer 2018. We show that integrated nutrients concentrations were higher at the cyclone compared to the anti-cyclone or the background stations by 2–13 fold. Concurrently, Synechococcus and Prochlorococcus were the dominant community component abundance-wise in the oligotrophic anti-cyclone (~300 × 1010 cells m−2). In the cyclone, pico- and nanoeukaryotes such as dinoflagellates, Prymnesiophyceae and Ochrophyta contributed substantially to the total phytoplankton abundnce (~14 × 1010 cells m−2) which was ~65 % lower in the anti-cyclone/background stations (~5 × 1010 cells m−2). Primary production was highest in the cyclonic eddy (191 mg C m−2 d−1) and was 2–5 fold lower outside the eddy area. The calculated doubling time of phytoplankton was ~3 days in the cyclone and ~5–10 days at the anti-cyclone/background stations, further reflecting the nutritional differences between these environments. Heterotrophic prokaryotic cell-specific activity was highest in the cyclone (~10 fg C cell−1 d−1), while the least productive cells were found in the anti-cyclone (4 fg C cell−1 d−1). The calculated doubling time of heterotrophic bacteria were 1.4 days in the cyclone and 2.5–3.5 days at the anti-cyclone/background stations. Total zooplankton biomass in the upper 300 m was tenfold higher in the cyclone compared with the anti-cyclone or background stations (1337 vs. 112–133 mg C m−2, respectively). Copepod diversity was much higher in the cyclone (44 species), compared to the anti-cyclone (6 small-size species). Our results highlight that cyclonic and anti-cyclonic eddies show significantly different community compositions and food-web dynamics in oligotrophic environments, with cyclones representing productive oases in the marine desert of the SEMS.

“…Similar research has been conducted by Juniar et al (2021) regarding the molecular identification of the COI gene in specimens from the northern coast, Madura, Indonesia which shows a species similarity level of C. oualaniense at 98.26-100%. In addition, molecular identification using the COI gene in Neritidae members has been carried out by Rabi et al (2020) on the Mediterranean coast, Israel, to a high level of similarity of species from Nerita sanguinolenta Menke 1829 at 99.04-99.36%.…”

Abstract. Djoemharsjah IS, Ambarwati R, Rahayu DA. 2023. DNA barcoding Clithonsp. (Gastropoda: Neritidae) from Badur Beach, Madura, Indonesia, based on COI gene molecular marker. Biodiversitas 24: xxxx. Neritidae is polymorphic with various shell colors and patterns; therefore, they were doubts about the identifying species from the genus Clithon, namely Clithon sp. from Badur Beach of Madura Island, Sumenep District, East Java Province, Indonesia. In addition, DNA barcoding could provide genetic information using short DNA sequences to quickly and precisely identify species. This study aimed to identify the genus Clithon sp. from Badur Beach, based on Cytochrome Oxidase subunit I(COI) genes and analysis of phylogenetic relationships. The research methods include sampling, sample preservation, morphological identification of species, DNA isolation, amplification, electrophoresis, and sequencing using the Sanger method with genetic analysis using bioinformatics software. The results of COI barcode identification obtained a DNA sequence length of 490bp with a similarity value of the three Clithon sp. samples between 96.75 to 98.97%. The identification with the Barcode of Life Data System consisted of three variations of nucleotide bases, and the average value of the genetic distance with the in-group was 1.74% as Clithon sp. The Phylogenetic tree Clithon sp. from Badur Beach, was in the same clade as Clithon sowerbianum Récluz 1843 and Clithon mertonianum Récluz 1843 with the Neighbor-Joining Tree and Maximum Likelihood methods with bootstrap values between 96-100. Therefore, the COI barcode DNA markers analysis successfully identified Clithon sp. from Badur Beach, Madura, Indonesia as C. sowerbianum.
