Determinants of Tubastraea coccinea invasion and likelihood of further expansion in the northern Gulf of Mexico

Invasive species have large economic and ecological impacts and are the leading driver of extinction for both plants and animals worldwide. In the USA, coral reefs, which provide $3.4 billion per year in ecosystem services, are impacted by invasive marine species. One such species is Tubastraea coccinea, which was the first scleractinia to invade the western Atlantic and recently has spread to natural reefs within the northern Gulf of Mexico (GoM). We document this recent invasion by compiling occurrence records, develop a species distribution model identifying important determinants of invasion, and project potential range expansion. Our results indicate T. coccinea currently is distributed along the GoM coast from the Florida Keys to southern Texas, with documented localities clustered ≈ 100 km off the Louisiana coast and ≈ 200 km off the Texas coast, and sparsely distributed elsewhere. Our species distribution model identified five environmental factors that together contribute > 99% to the overall model. These factors include two surface variables (mean pH and mean calcite, contributing ≈ 40%) and three benthic variables (maximum current velocity, minimum iron, and minimum dissolved oxygen, contributing ≈ 60%). Our model suggests potential habitat for range expansion is distributed mainly within the western portion of the northern GoM, with the highest probabilities of occurrence (0.8 < P < 1.0) clustered along the Texas and Louisiana coasts between 88 and 97°W (near the border between states).

We reported the genus Parasphyraenops (Perciformes: Serranidae) in the Brazilian Biogeographic Province. Four Parasphyraenops incisus specimens were identified based in body shape and color pattern through underwater remote video records, on shallow coral reefs in the Bahia state, Brazil. In the video frames P. incisus was observed swimming close to the pomacentrid Chromis multilineata at 14 m depth, being this the shallowest record for this species. The present record expands on 6.500 km the southern limit of distribution of P. incisus in the Western Atlantic.

“…The impacts of climate change over reefs are varied: marine heatwaves may be severe causing widespread bleaching and mortality ( Fordyce et al , 2019 ; Leggat et al , 2019 ), while more moderate events may cause bleaching with little to no mortality ( Heron et al , 2016 ). Warmer temperatures have also been linked to outbreaks of coral disease ( Heron et al , 2010 ; Randall and van Woesik, 2015 ) and the emergence of novel species interactions ( Miranda et al , 2018 ; Vergés et al , 2019 ). As such the preservation of reefs requires effective management plans that can mitigate the cumulative negative impacts of both local and global stressors to conserve ecosystem function.…”

High flow conditions mediate damaging impacts of sub-lethal thermal stress on corals’ endosymbiotic algae

The effects of thermal anomalies on tropical coral endosymbiosis can be mediated by a range of environmental factors, which in turn ultimately influence coral health and survival. One such factor is the water flow conditions over coral reefs and corals. Although the physiological benefits of living under high water flow are well known, there remains a lack of conclusive experimental evidence characterizing how flow mitigates thermal stress responses in corals. Here we use in situ measurements of flow in a variety of reef habitats to constrain the importance of flow speeds on the endosymbiosis of an important reef building species under different thermal regimes. Under high flow speeds (0.15 m s−1) and thermal stress, coral endosymbionts retained photosynthetic function and recovery capacity for longer compared to low flow conditions (0.03 m s−1). We hypothesize that this may be due to increased rates of mass transfer of key metabolites under higher flow, putatively allowing corals to maintain photosynthetic efficiency for longer. We also identified a positive interactive effect between high flow and a pre-stress, sub-lethal pulse in temperature. While higher flow may delay the onset of photosynthetic stress, it does not appear to confer long-term protection; sustained exposure to thermal stress (eDHW accumulation equivalent to 4.9°C weeks) eventually overwhelmed the coral meta-organism as evidenced by eventual declines in photo-physiological function and endosymbiont densities. Investigating flow patterns at the scale of metres within the context of these physiological impacts can reveal interesting avenues for coral reef management. This study increases our understanding of the effects of water flow on coral reef health in an era of climate change and highlights the potential to learn from existing beneficial bio-physical interactions for the effective preservation of coral reefs into the future.
