“…They included: two reef‐builders – a brooder coral and a broadcast‐spawning coral, which are essentially the two modes of larval development in scleractinian corals (Baird et al ); and two reef fishes – a roving herbivorous fish (surgeonfish) and a large carnivorous fish (snapper), regarded as playing critical roles in ecological processes and having fisheries importance on coral‐reef ecosystems (Bellwood et al , Graham et al ). Life‐history parameters were obtained from experimental or empirical observations within the study region (Pires et al , , Neves and Pires , Rocha et al , Neves and Silveira , Lins‐de‐Barros and Pires , Freitas et al ). Although the values used for these parameters do not represent species‐specific information, they reflect plausible values for keystone species with significant ecological value for coral reefs.…”

Integrating multiple species connectivity and habitat quality into conservation planning for coral reefs

Incorporating connectivity into the design of marine protected areas (MPAs) has met with conceptual, theoretical, and practical challenges, which include: 1) the need to consider connectivity for multiple species with different dispersal abilities, and 2) the role played by variable habitat quality in determining the spatial patterns of connectivity. We propose an innovative approach, combining biophysical modeling with a routinely-used tool for marine-reserve design (Marxan), to address both challenges by using ecologically-informed connectivity parameters. We showed how functional demographic connectivity for four candidate reef-associated species with varying dispersal abilities and a suite of connectivity metrics weighted by habitat quality can be used to set conservation objectives and inform MPA placement. Overall, the strength of dispersal barriers varied across modeled species and, also across species, we found a lack of spatial concordance of reefs that were high-quality sources, self-persistent, and stepping-stones. Including spatially-heterogeneous habitat quality made a considerable difference to connectivity patterns, significantly reducing the potential reproductive output from many reefs. We also found that caution is needed in combining connectivity data from modeled species into multi-species matrices, which do not perform reliably as surrogates for all connectivity metrics of individual species. We then showed that restricting the habitat available for conservation has an inequitable impact on different connectivity objectives and species, with greatest impact on betweenness centrality and long-distance dispersers. We used Brazilian coral reefs as a case study but our approach is applicable to both marine and terrestrial conservation planning, and offers a holistic way to design functionally-connected reserves to tackle the complex issues relevant to planning for persistence.

“…Brazilian coral species have high level of endemism and are predominantly found in shallow waters, with the scleractinian coral Siderastrea stellata (Verril, 1868) being one of the main reef builders. It is a colonial, massive, and symbiotic coral (Lins-de-Barros and Pires, 2007) with a spatial distribution that encloses all Brazilian reefs and coral communities from nearly 0 to 23 • S (Castro and Pires, 2001). For Siderastrea stellata, that often grows in shallow water in reef tidal pools (where temperatures normally range between 25 and 31 • C), optimum calcification has been observed at temperatures between 28 and 30 • C. For this particular species, the aragonite saturation seems to play a less relevant role than SST for calcification, especially when SST reaches ∼ 26 • C (da Silva et al, 2009).…”

Ideas and perspectives: Southwestern tropical Atlantic coral growth response to atmospheric circulation changes induced by ozone depletion in Antarctica

Abstract. Recent Southern Hemisphere (SH) atmospheric circulation, predominantly driven by stratospheric ozone depletion over Antarctica, has caused changes in climate across the extratropics. Here, we present evidence that the Brazilian coast (southwestern Atlantic) may have been impacted from both wind and sea-surface temperature changes derived from this process. Skeleton analysis of massive coral species living in shallow waters off Brazil are very sensitive to air-sea interactions, and seem to record this impact. Growth rates of Brazilian corals show a trend reversal that fits the ozone depletion evolution, confirming that ozone impacts are far reaching and potentially affect coastal ecosystems in tropical environments.

Abstract. Climate changes induced by stratospheric ozone depletion over Antarctica have been recognized as an important consequence of the recently observed Southern Hemisphere atmospheric circulation. Here we present evidences that the Brazilian coast (Southwestern Atlantic) may have been impacted from both winds and sea surface temperature changes derived from this process. Skeleton analysis of massive coral species living in shallow waters off Brazil are very sensitive to air–sea interactions, and seem to record this impact. Growth rates of Brazilian corals show a trend reversal that fits the ozone depletion evolution, confirming that ozone impacts are far reaching and potentially affect coastal ecosystems in tropical environments.
