“…The relatively low number of predominantly self-seeding reefs modeled here contrasts with many other studies in different locations (Treml et al, 2008;Gilmour et al, 2009;Thomas et al, 2014), and is likely due to issues of scale. In most larger-scale studies, local recruitment that defines self-seeding occurs on spatial scales of km to a few 10s of km, whereas in Maui Nui, most of the existing MPAs are smaller than 1 km 2 and many of the larger reef tracts are separated by distances on the order of km to a few 10s of km.…”

Connectivity among individual marine protected areas (MPAs) is one of the most important considerations in the design of integrated MPA networks. To provide such information for managers in Hawaii, USA, a numerical circulation model was developed to determine the role of ocean currents in transporting coral larvae from natal reefs throughout the high volcanic islands of the Maui Nui island complex in the southeastern Hawaiian Archipelago. Spatially-and temporally-varying wind, wave, and circulation model outputs were used to drive a km-scale, 3-dimensional, physics-based circulation model for Maui Nui. The model was calibrated and validated using satellite-tracked ocean surface current drifters deployed during coral-spawning conditions, then used to simulate the movement of the larvae of the dominant reef-building coral, Porites compressa, from 17 reefs during eight spawning events in 2010-2013. These simulations make it possible to investigate not only the general dispersal patterns from individual coral reefs, but also how anomalous conditions during individual spawning events can result in large deviations from those general patterns. These data also help identify those reefs that are dominated by self-seeding and those where self-seeding is limited to determine their relative susceptibility to stressors and potential roadblocks to recovery. Overall, the numerical model results indicate that many of the coral reefs in Maui Nui seed reefs on adjacent islands, demonstrating the interconnected nature of the coral reefs in Maui Nui and providing a key component of the scientific underpinning essential for the design of a mutually supportive network of MPAs to enhance conservation of coral reefs.

“…September/October events were dominated by faviids and agaricids, while March/April by acroporids. This is the first indication that there are two peak periods of spawning in the Java Sea, a phenomenon that appears to be common in Southeast Asia (Guest et al 2005;Baird et al 2009) and North Western Australia (Gilmour et al 2009). The two distinct spawning seasons appear to be associated with changes in the monsoon that likely are driven by two annual peaks in insolation and or temperature (van Woesik et al 2006).…”

“…Finally, although a heavily debated issue, the mode of transmission of coral species is likely to affect their likelihood of recruitment to and within the Kermadec Islands. Most brooding corals have larvae that are competent to settle within a few hours or a few days after release (Richmond 1987, Harrison 2006, Gilmour et al 2009), which promotes settlement on, or close to, the natal reef (e.g. Tioho et al 2001).…”

The Kermadec Islands Marine Reserve (29 to 31°S), New Zealand, harbours one of the world's highest latitude scleractinian coral communities, situated close to the lower thermal limits for coral survival. An understanding of how and why similarities and differences exist between so-called 'marginal' coral communities can provide insight into the physical and biological factors that influence coral distributions. In this study, a depth-stratified survey of benthic community structure and coral species assemblages was conducted at 9 sites around the Kermadec Islands. All coral species identified were subtropical non-reef building species, or species with a wide geographic range. Scleractinian coral cover (16 species) was low and variable between sites and depths (5.3 ± 13.9%, mean ± SD) with macroalgae contributing between 36 to 95% of the benthic cover. Multivariate analyses revealed small-scale spatial variability between closely located sites. Resulting data on coral species diversity were compared to published data from coral communities at other 'marginal' locations, as well as those from a range of Australian locations. On a global scale, the Kermadec Islands coral community exhibits greatest affinity with southeastern Australian sites. In comparison, there was a lack of affinity for Australian tropical sites and other high latitude sites, both in Australia and globally. Our analyses suggest that the low diversity, highly variable coral communities of the Kermadec Islands are likely shaped by their isolation and high wave energy, in addition to the low annual temperatures experienced.KEY WORDS: High latitude · Coral community · Kermadec Islands · Regional affinities · Subtropical · New Zealand Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 400: [101][102][103][104][105][106][107][108][109][110][111][112][113] 2010 Marginal reefs and communities frequently occur at high latitudes (subtropics) i.e. above 25°S and 25°N, with well known examples being those of the Persian Gulf, Bermuda, Japan and Lord Howe Island, Australia. Development and coral species diversity of these high-latitude assemblages, at both biogeographic and local scales, are largely regulated by low mean annual and seasonally variable temperatures and irradiances, and the low aragonite saturation state (Buddemeier 1997, Kleypas et al. 1999). Other parameters with local importance include wave exposure (Harriott et al. 1994, Benzoni et al. 2003, Nozawa et al. 2008, low and variable salinity and high turbidity (Harriott & Smith 2002, Manzello & Lirman 2003. Macroalgae play a dominant role in many of these high latitude coral assemblages, their rapid growth out-competing corals for space (Johannes et al. 1983). Further, many high latitude coral assemblages are small and isolated (e.g. Babcock et al. 1986, Brook 1999, Hughes et al. 2002, meaning that they are likely to be largely self-seeding in terms of larval supply (Ayre et al. 1997).Patterns of diversity and distribution in high latit...
