“…The lagoon has a total estimated annual economic value of $7.6 billion [ 2 ]. It is connected, at its southern end, to the St. Lucie Estuary (SLE), another important resource for the area [ 3 ]. The IRL has a high biodiversity because it is located at the border between temperate and sub-tropical regions, allowing it to have plant and animal species from both climates [ 4 ].…”

“…Freshwater is introduced into the IRL via runoff from local waterways and, most prominently, discharges from Lake Okeechobee, which are diverted into the SLE through the C-44 canal during periodic releases based upon the Lake’s water level [ 3 ]. This introduction of freshwater and its associated contaminants causes problems for the ecosystem [ 3 ]. The high flow conditions and drastic reduction of salinity associated with these discharges is so prominent in the SLE that it has reduced and prevented the recovery of oyster reefs [ 6 ].…”

Defining the sediment prokaryotic communities of the Indian River Lagoon, FL, USA, an Estuary of National Significance

et al. 2020

The Indian River Lagoon, located on the east coast of Florida, USA, is an Estuary of National Significance and an important economic and ecological resource. The Indian River Lagoon faces several environmental pressures, including freshwater discharges through the St. Lucie Estuary; accumulation of anoxic, fine-grained, organic-rich sediment; and metal contamination from agriculture and marinas. Although the Indian River Lagoon has been well-studied, little is known about its microbial communities; thus, a two-year 16S amplicon sequencing study was conducted to assess the spatiotemporal changes of the sediment bacterial and archaeal groups. In general, the Indian River Lagoon exhibited a prokaryotic community that was consistent with other estuarine studies. Statistically different communities were found between the Indian River Lagoon and St. Lucie Estuary due to changes in porewater salinity causing microbes that require salts for growth to be higher in the Indian River Lagoon. The St. Lucie Estuary exhibited more obvious prokaryotic seasonality, such as a higher relative abundance of Betaproteobacteriales in wet season and a higher relative abundance of Flavobacteriales in dry season samples. Distance-based linear models revealed these communities were more affected by changes in total organic matter and copper than changes in temperature. Anaerobic prokaryotes, such as Campylobacterales, were more associated with high total organic matter and copper samples while aerobic prokaryotes, such as Nitrosopumilales, were more associated with low total organic matter and copper samples. This initial study fills the knowledge gap on the Indian River Lagoon bacterial and archaeal communities and serves as important data for future studies to compare to determine possible future changes due to human impacts or environmental changes.

“…Bivalves from genus Anadara (Handayani et al 2015) and Paphia (Zarkasyi et al 2016) preferred waters with higher salinity. McKeon et al (2015) stated that the grouping of bivalve communities occurred due to different salinity. Salinity affected production, distribution, lifespan, and migration orientation of bivalves (Islami 2013).…”

Susetya IE, Desrita, Ginting EDD, Fauzan M, Yusni E, Saridu SA. 2018. Diversity of bivalves in Tanjung Balai AsahanWaters, North Sumatra, Indonesia. Biodiversitas 19: 1147-1153. Local and regional market demands for bivalves increase outsideTanjung Balai City and Asahan District Waters, North Sumatra, Indonesia. As a result, high exploitation of bivalves occurred. In theother hand, there were less comprehensive information and studies on the diversity of bivalves in this area. This study aimed todetermine the diversity of bivalves and water quality of Tanjung Balai Asahan Waters; was conducted between July 2016 and November2017. Sampling of bivalves was conducted monthly. Several physical and chemical parameters were quantified. Data analysis includedcommunity structure analysis and Principal Component Analysis (PCA). The result showed that there were 16 species of bivalves from7 families in Tanjung Balai Asahan Waters. Station 2 had the highest composition of bivalves, while the lowest was noted at Station 1.The mean abundance of bivalves at stations 1, 2 and 3 were 352±22 ind/m2, 222±14 ind/m2 and 388±30,2 ind/m2, respectively. Ingeneral, the index of diversity was categorized as low to moderate. The evenness index was categorized as low to high, while thedominance index indicated the absence of dominant species at almost all stations except station 1. Water quality of the waters was stillin capacity to support the life of bivalves. Based on PCA analysis, it was obtained that the abundance of bivalves was positivelycorrelated with nitrite, nitrate, phosphate, salinity, and pH.

“…A high degree of phenotypic plasticity allows organisms to adapt physically and behaviourally to spatially and temporally variable environments, allowing them to survive under climatic changes (West-Eberhard, 2003; Murren et al , 2015). Inhabiting highly diverse and changeable marine habitats, bivalves are subjected to several ecological drivers of species distribution (McKeon et al , 2015), which further contributes to high phenotypic plasticity being reflected in great morphological diversity.…”

Morphometric relationships and relative growth of 20 uncommon bivalve species from the Algarve coast (southern Portugal)

This study reports the morphometric relationships and relative growth of 20 uncommon bivalve species collected along the Algarve coast (southern Portugal). Morphometric relationships were established between three linear variables (shell length, height and width) and one ponderal variable (total weight) and the relative growth between variables (isometry vs allometry) was analysed in order to assess their variation throughout ontogeny. In addition, morphometric indices (elongation, compactness, convexity and density) based on ratios of those linear and ponderal variables were calculated in order to further characterize morphologically the bivalve species. A total of 2512 individuals belonging to nine bivalve families were analysed, comprising specimens with broad ranges in both shell length (11.8–109.0 mm SL) and total weight (0.2–354.6 g TW). All morphometric relationships were highly significant (P < 0.001) and displayed invariably high correlation coefficients (r = 0.727–0.998). Among a total of 60 morphometric relationships, 27 isometries, 25 positive allometries and 8 negative allometries were registered. The morphometric indices displayed a remarkable variation among taxa, reflecting the high morphological diversity of these miscellaneous bivalve species. Discriminant analysis provided a spatial visualization of the species morphometric variables that further evidenced their main shape features, the distinctness between some species and families (e.g. Pharidae and Cardiidae) and the morphological resemblance among some species belonging to other families (e.g. Veneridae and Tellinidae). Overall, this information is useful and has practical application in diverse research fields, including studies on systematics and taxonomy, physiology, biology, ecology, fisheries assessment and management.
