“…In the specimens analyzed, we observed some morphological variations such as epitheca slightly conical to (more commonly) rounded (Figure 2). Our material is morphologically like those described by Carty (2014), who also described cells with rounded epitheca. This polymorphism can be explained by changes in water temperature (Popovský & Pfiester 1990).…”

“…The species was identified using specialized literature (Carty 2008;Lewis & Dodge 2011;Carty 2014), and plate designation was based on Kofoid (1909). Samples of P. umbonatum, fixed in Transeau's solution, were observed using an Olympus light microscope (LM; model BX-43), and the digital images were taken with a 5.0-MP QImaging camera using the software Image-Pro Premier 9.1.4.…”

“…There are two species morphologically related to Parvodinium umbonatum recorded from Brazil: P. africanum and P. inconspicuum (Menezes et al 2015). The former differs from P. umbonatum by having thecal plates with vertical surface striations whereas P. inconspicuum has cells are approximately pentagonal, the cingulum is more equatorial, and the apical pore is prominent (Carty 2008;Tardio et al 2009;Lewis & Dodge 2011;Carty 2014).…”

This paper presents the first record of the freshwater dinoflagellate Parvodinium umbonatum (Stein) Carty (Peridiniaceae, Dinophyta) for northeast Brazil, based on samples collected in 2015 from a tank bromeliads at Serra da Jiboia, Bahia. This species was an important component in the local phytotelm community and categorized as frequent in the bromeliads of the area. A description based on morphometrical features, illustrations (LM and SEM), abiotic conditions of the stored water, and geographic distribution of P. umbonatum in Brazil are provided.

Algal blooms in a river-dominated estuary and nearshore region of Florida, USA: the influence of regulated discharges from water control structures on hydrologic and nutrient conditions

et al. 2023

Flow-regulated discharges of water from control structures into estuaries result in hydrologic and water chemistry conditions that impact spatial and temporal variability in the structure and biomass of phytoplankton communities, including the potential for harmful algal blooms (HABs). The relationships between regulated Caloosahatchee River (i.e., C-43 Canal) discharges and phytoplankton communities in the Caloosahatchee Estuary and adjacent nearshore regions on the southwest coast of Florida were investigated during two study periods, 2009–2010 and 2018–2019. During periods of low to moderate discharge rates, when mesohaline conditions predominated in the estuary, and water residence times were comparatively long, major blooms of the HAB dinoflagellate species Akashiwo sanguinea were observed in the estuary. Periods of high discharge were characterized by comparatively low phytoplankton biomass in the estuary and greater influence of a wide range of freshwater taxa in the upper reaches. By contrast, intense blooms of the toxic dinoflagellate Karenia brevis in the nearshore region outside of the estuary were observed during high discharge periods in 2018–2019. The latter events were significantly associated with elevated levels of nitrogen in the estuary compared to lower average concentrations in the 2009–2010 study period. The relationships observed in this study provide insights into the importance of managing regulated discharge regimes to minimize adverse impacts of HABs on the health of the estuary and related coastal environments.
