Trophic Interactions, Habitat Use, and Pollution Loads of Bottlenose Dolphins (Tursiops Truncatus) in the Florida Coastal Everglades, Florida, USA, 2013-2019
Cetaceans can feed at upper trophic levels and occur from freshwater to open-ocean ecosystems. Due to their abundance, mobility, and high metabolic rates, they have the potential to affect the structure and function of ecosystems through both top-down and bottom-up pathways. To better understand what ecological roles they may play in a system, it is important to understand patterns and drivers of their abundance, habitat use, and trophic interactions. I investigated the trophic interactions and pollutant exposure of common bottlenose dolphins (Tursiops truncatus) of the Florida Coastal Everglades. Based on bulk stable isotope analysis of tissue samples collected using biopsy sampling, it appears that despite their high mobility, bottlenose dolphins restrict their foraging within the habitats where they were sampled. Trophic position and foraging locations affected exposure to pollutants, with high levels of mercury found in dolphins estimated to forage at higher trophic levels and feeding within an inland bay. Mercury levels also varied with age and sex. Dolphins and their prey both contained substantial mercury levels and dolphins’ health could be impacted by this exposure, but the selenium levels we measured might counteract these negative effects.

Fig. 2. Sightings of bottlenose dolphins near Sudak in 2011–2012. Sightings are indicated by circles of different size, depending on the group size category; sightings during the line transect survey (LTS) on August 4, 2012, are marked as filled circles, and other sightings (non LTS) are marked as empty circles. The LTS transects are shown as a zigzag line, and the LTS area is bordered by a contour line.

Fig. 3. Dose, kinetic and functional inhibition assays of N. caninum tachyzoites-triggered NET formation in dolphins. PMN were incubated with tachyzoites, zymosan (1 mg/ ml, positive control) or plain medium (negative control) at different ratios (a; PMN: tachyzoites = 1:1, 1:2, 1:3) and time periods (b; 30, 60 and 90 min). To prove the DNA nature of NETs, the samples were treated with DNase I (a; 15 min). Moreover, cetacean PMN cells were pre-treated with NOX-inhibitor (b; DPI, 10 MM) for 30 min prior to N. caninum stimulation (1:3 ratio; 90 min). After incubation, all samples were analyzed for extracellular DNA by quantifying Pico Green ®-derived fluorescence intensities. Each condition was performed in duplicates. Geometric means of three PMN donors. Differences were regarded as significant at a level of p <0.05 (*) and p <0.01 (**).

(a‾d) Scanning electron microscopy (SEM) analyses revealed NETs being formed by dolphin PMN after co-culture with N. caninum tachyzoites.

(b) Intact cetacean-PMN (black stars) derived a fine filaroid structure (white arrow) being attached to tachyzoites (black arrows).

(e‾l) Co-cultures of dolphin PMN and N. caninum tachyzoites were fixed, permeabilized, stained for analysis of co-localization (i-l; merge, white arrows) of extracellular DNA (e-h; red; Sytox Orange ®) and classical NETs components (all green, white arrows) such as histones (i), NE (j), MPO (k) and pentraxin (l).
