Tinental shelf (Fig 1). 3 years prior to this, an extensive study linking fish and coral species diversity was undertaken at 14 internet sites around Lizard Island, enabling the examination of the underlying effects of diverse exposure regimes on changes within the fish communities of Lizard Island coral reefs following Cyclone Ita. In specific, we ask the following concerns: ?How did coral cover, fish density, biomass, species richness and assemblage structure transform following Cyclone Ita, and did modifications differ among web-sites with unique exposure regimes? ?Did certain species endure greater declines than other folks, and are there constant patterns in their trophic affiliations? ?How well did the results at broad resolutions (e.g. total abundance) examine with those performed at finer resolution, such as species level analyses? We show that the degree of modify measured at coarse levels masked high species-level turnover, and that fish neighborhood changes soon after the cyclone were strongly affected by wave exposure and depth.Materials and MethodsCoral and fish communities were surveyed at fourteen web-sites at Lizard Island around the northern Terrific Barrier Reef (14?9.873S, 145?six.715E) in September 2011 and once again in January 2015 (Fig 1), 10 months soon after Cyclone Ita crossed the island. This analysis was conducted at Lizard Island Study Station, a facility in the Australian Museum. Permits to conduct the investigation are granted by the Terrific Barrier Reef Marine Park Authority; relevant permits are held by the Museum. The field research didn’t involve protected or endangered species, and no ethics approvals were necessary. The web sites were selected to maximise the diversity of habitats and exposure regimes located at Lizard Island, including protected fringing and patch reefs, lagoonal habitats, reef passes and steep reefs slopes exposed for the VUF10460 web prevailing climate. Sites were classified by exposure for the prevailing sou-easterly trade winds and incorporated four sheltered (northwest facing), three lagoon, 4 oblique (northeast and southwest facing) and three exposed (southeast facing) web sites (Fig 1). Coral and reef fish surveys have been conducted concurrently at two depths per web page; shallow (35m) and deep (8-10m). The very first observer (alternately MJE and DMC in 2011; DMC in 2015) recorded the abundance and size (total length for the nearest cm) of all diurnal, non-cryptic reef fish species along three 50 m transects (five m wide belt for bigger, mobile fishes and 1 m wide belt for smaller sized, site-attached fishes). Fish density was expressed as individuals per 1000 m2; species richness was applied as a measure of diversity. Biomass was calculated according toPLOS 1 | DOI:ten.1371/journal.pone.0156232 June 10,3 /Cyclones and Coral Reef Fish Community ChangeFig 1. Lizard Island and Serious Tropical Cyclone Ita. A.
