Tinental shelf (Fig 1). Three years before this, an comprehensive study linking fish and coral species diversity was undertaken at 14 web-sites about Lizard Island, enabling the examination from the underlying effects of distinct exposure regimes on adjustments in the fish communities of Lizard Island coral reefs following Cyclone Ita. In certain, we ask the following questions: ?How did coral cover, fish density, biomass, species richness and assemblage structure adjust following Cyclone Ita, and did alterations vary amongst web pages with unique exposure regimes? ?Did certain species suffer higher declines than others, and are there consistent patterns in their trophic affiliations? ?How effectively did the results at broad resolutions (e.g. total abundance) examine with those done at finer resolution, including species level analyses? We show that the degree of modify measured at coarse levels masked higher species-level turnover, and that fish community alterations right after the cyclone had been strongly affected by wave exposure and depth.Supplies and MethodsCoral and fish communities have been surveyed at fourteen web pages at Lizard Island around the northern Fantastic Barrier Reef (14?9.873S, 145?6.715E) in September 2011 and again in January 2015 (Fig 1), 10 months following Cyclone Ita crossed the island. This research was carried out at Lizard Island Research Station, a facility on the Australian Museum. Permits to conduct the research are granted by the Terrific Barrier Reef Marine Park Authority; relevant permits are held by the Museum. The field studies did not involve protected or endangered species, and no ethics approvals were required. The internet sites were selected to maximise the diversity of habitats and exposure regimes discovered at Lizard Island, such as protected fringing and patch reefs, lagoonal habitats, reef passes and steep reefs slopes exposed to the prevailing climate. Web sites were classified by exposure towards the prevailing sou-easterly trade winds and integrated four NSC23005 (sodium) site Sheltered (northwest facing), three lagoon, four oblique (northeast and southwest facing) and 3 exposed (southeast facing) websites (Fig 1). Coral and reef fish surveys have been carried out concurrently at two depths per website; shallow (35m) and deep (8-10m). The initial observer (alternately MJE and DMC in 2011; DMC in 2015) recorded the abundance and size (total length to the nearest cm) of all diurnal, non-cryptic reef fish species along 3 50 m transects (5 m wide belt for bigger, mobile fishes and 1 m wide belt for smaller, site-attached fishes). Fish density was expressed as people per 1000 m2; species richness was used as a measure of diversity.
