“…The spatial variability of plankton's biomass (Mompean et al, 2013) is influenced by its size (Flynn et al, 2013). Different studies on plankton (Aleksandrov et al, 2009;Bagheri et al, 2012;Dvoretsky, Venger, Makarevich, & Moiseev, 2012;Caric, Jasprica, Krsinic, Vilibic, & Batistic, 2012;Selifonova, 2012;Motylkova & Konovalova, 2010) depicted biomass, abundance, and density determination as these factors are also correlated to oceanographic processes and events (Dvoretsky et al, 2012), temperature (Radchenko, Loboda, Figurkin, Gorbatenko, & Ovsyannikov, 2010), and behavioral patterns (Berge et al, 2014) of the organisms.…”

“…The effect of population size is on primary production (Petitgas et al, 2006) since the phytoplankton SPATIAL DISTRIBUTION OF MARINE PLANKTONS OFF THE COAST OF SITRA 355 is considered the producer (McManus & Woodson, 2012) of the marine ecosystems which inhabit the illuminated (Aleksandrov et al, 2009) part of the sea water. Dinoflagellates are also considered common coastal plankton (Somshekar et al, 2004).…”

“…The zooplankton includes many crustacean larvae (Petitgas et al, 2006) which become food for other plankton (McManus & Woodson, 2012). The spatial distribution of planktons is influenced by the physical characteristic of the ocean water (Aleksandrov et al, 2009). Vertical migration is also described as a synchronized movement of both phytoplankton and the zooplankton (Petitgas et al, 2006).…”

“…The physical structures and processes are important driving force for the distribution and dispersal of the organism. This is attributed to the swimming and behavioral capabilities of individual species (Aleksandrov, Zhigalova, & Zezera, 2009). There is unlimited horizontal distribution of plankton.…”

Determination of the spatial distribution of marine plankton off-coast of Sitra, Kingdom of Bahrain was conducted from August 2014-July 2015 to identify, categorize, and classify taxonomically the phyto-and-zooplankton.Population size was calculated based on abundance, density, and biomass from the collected water samples. Results showed 20 species of phytoplankton and 14 species of zooplankton. The phytoplankton includes 13 species which belong to Phylum Chrysophyta or diatoms, and seven species in Phylum Dinoflagellata or dinoflagellates. The 14 species of zooplankton were categorized to eight phyla-Protozoa, Cnidaria, Platyhelminthes, Rotifer, Annelida, Mollusca, Arthropoda, and Chordata. The identified species of phytoplankton and zooplankton vary in abundance, density, and biomass. Fragillariopsis and Navicula species were identified as the most abundant phytoplankton with higher density and biomass while Ceratium furca and Ceratium fusus of the zooplankton. Statistical analysis using ANOVA (Analysis of Variance) revealed significant differences at p = 0.05 on abundance and density, however, insignificant difference in biomass. Based on dispersion index, the phytoplankton and zooplankton were found to be vertically distributed and aggregated mostly on the upper column where sunlight is abundant. Surface water temperature and salinity significantly affect the spatial distribution and population size of the identified marine plankton.

“…Johannesson and André () did not analyze any zooplankton species in their study. In total, only about 20 marine, holoplanktonic, mesozooplankton species managed to colonize and reproduce in the Baltic proper, resulting in truly autochthonous populations (Aleksandrov, Zhigalova, & Zezera, ; FEMA‐FEHY, ; Hällfors, Niemi, Ackefors, Lassig, & Leppäkoski, ). Among these, crustaceans prevail.…”

This study assessed the genetic relationship between Evadne nordmanni of the Baltic Sea and the North Sea from sequence variation of the mitochondrial cytochrome c oxidase subunit I gene (COI) of 88 specimens from 13 different sites, and from further published data from the Atlantic and Pacific basins. The COI sequences of E. nordmanni from the North and Baltic Seas were represented by a coherent cluster of 28 haplotypes dominated by a central haplotype that accounted for over half of the individuals from these seas, from all samples except one from the Arkona Basin (Baltic Sea). Overall, the North and Baltic Sea populations appear relatively homogenous and the North Sea plausibly represents the source population for the Baltic one. However, the haplotype network also involved a haplogroup of exclusively Baltic Sea haplotypes, comprising four haplotypes represented by 21 individuals and strongly dominated by specimens from the Arkona basin. This inspires discussion about the post‐glacial evolution of a genetically distinct Baltic Sea group, related to a special local salinity regime. Partly as a reflection of the presence of the unique haplogroup, the mean haplotype diversity in the Baltic was twice as high as the mean diversity in the North Sea, h = 0.64 versus h = 0.30.
