“…It can respond quickly to changes in its habitat (Crow 1979 ) and accumulate copper, nickel, zinc, cadmium and silver (Bielmyer-Fraser et al. 2022 ), indicating a high potential for Z. palustris in bio-monitoring and phytoremediation of heavy metals in water. The taxonomic classification of the genus Zannichellia has been contentious.…”

Zannichellia palustris Linnaeus 1753 is a cosmopolitan submerged species capable of rapidly responding to environmental changes, with potential applications in the ecological treatment of heavy metal pollution in water bodies. This study aimed to characterize the complete chloroplast genome of Z. palustris , which has not been reported previously. The chloroplast genome of Z. palustris displays a quadripartite structure with a length of 155,262 base pairs (bp), comprising a large single copy (LSC) region of 85,397 bp, a small single copy (SSC) region of 18,057 bp, and a pair of inverted repeat (IR) regions of 25,904 bp. The GC content of the genome is 35.8%, with corresponding values of 33.4% for the LSC, 28.2% for the SSC, and 42.5% for the IR regions. The genome contained 130 genes, including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis within the order Alismatales revealed that Z. palustris clusters with the clade of Potamogeton perfoliatus , P. crispus and Stuckenia pectinata .

The St. Johns River (SJR) is a dynamic system, spanning 310 miles of Florida’s eastern coast and provides ecological, recreational, and commercial benefit for the state. The lower SJR basin, located near Jacksonville, forms an estuarine environment where tidal flow from the Atlantic Ocean mixes with freshwater moving through the river toward the ocean. Anthropogenic influences, such as increased development, dredging, and wastewater discharge from a variety of sources has changed the water quality in the river over past years. In this study, a variety of water quality parameters and a suite of metals were measured in water samples collected from eight sites in the lower SJR from 2019 to 2022, continued from previous work which documented these parameters in the river from 2017 to 2019. Aquatic communities such as phytoplankton can be indicative of river health, therefore, phytoplankton were collected from each site and the diatom component identified. The total number of taxa in each sample ranged from 60 to 190, with 25 taxa accounting for the majority (64%). The species Thalassiosira wongii was first discovered in the lower SJR during this study, previously documented from southern Brazil and the North Pacific. Like water chemistry, seasonal fluctuations in phytoplankton abundance and diversity were observed, with a relative abundance of Skeletonema costatum and Skeletonema subsalsum in times of lowered diversity. Further, decreased phytoplankton diversity correlated with increased metal contamination in the lower SJR. This study provides new information about the impact of human disturbance on biotic communities.
