229 Corrigendum Fishing and environmental influences on estimates of unfished herbivorous fish biomass across the Hawaiian Archipelago Jason Helyer, Jameal F. Samhouri* Mar Ecol Prog Ser 575: 1–15, 2017, https://doi.org/10.3354/meps12235 *Corresponding author: [email protected] • Following publication of the manuscript, David Bellwood pointed out that the functional group assignment for 4 of the 26 species considered were misclassified. Specifically, Chlorurus perspicillatus and Chlorurus sordidus are excavators and Ctenochaetus hawaiiensis and Ctenochaetus strigosus are detritivores or particulate feeders (Bellwood & Choat 1990, Bonaldo et al. 2014, Tebbett et al. 2017). However, in our paper the former 2 species were referred to as scrapers and the latter 2 species as grazers based on information contained within the citations we provided on p. 3−4 of the published manuscript. To acknowledge these misclassifications, Table S1 in Supplement 2 (www.int-res.com/articles/ suppl/m575p001_supp.pdf) has been revised. • In addition, throughout the manuscript readers should consider any reference to ‘scrapers’ to imply ‘scrapers and excavators’ and any reference to ‘grazers’ to imply ‘grazers and detritivores’. • Finally, we note that these corrections — while important in terms of their implications about the ecosystem functions of the herbivorous fishes we studied — do not relate to the main focus of our analysis, which was to estimate depletion from unfished biomass using herbivores as an example group.

Bellwood IUCN RESILIENCE SCIENCE GROUP WORKING PAPER SERIES - NO 7 IUCN Global Marine Programme Founded in 1958, IUCN (the International Union for the Conservation of Nature) brings together states, government agencies and a diverse range of non-governmental organizations in a unique world partnership: over 100 members in all, spread across some 140 countries. As a Union, IUCN seeks to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable. The IUCN Global Marine Programme provides vital linkages for the Union and its members to all the IUCN activities that deal with marine issues, including projects and initiatives of the Regional offices and the six IUCN Commissions. The IUCN Global Marine Programme works on issues such as integrated coastal and marine management, fisheries, marine protected areas, large marine ecosystems, coral reefs, marine invasives and protection of high and deep seas. The Nature Conservancy The mission of The Nature Conservancy is to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. The Conservancy launched the Global Marine Initiative in 2002 to protect and restore the most resilient examples of ocean and coastal ecosystems in ways that benefit marine life, local communities and economies.

MARINE ECOLOGY PROGRESS SERIES Vol. 164: 263-271,1998 Published April 9 Mar Ecol Prog Ser Intraspecific and interspecific relationships between host size and the abundance of parasitic larval gnathiid isopods on coral reef fishes Alexandra S. Grutter 'l*, Robert poulin2 'Department of Parasitology, The University of Queensland. Brisbane, Queensland 4072, Australia 'Department of Zoology, University of Otago. PO Box 56. Dunedin. New Zealand ABSTRACT: Parasitic gnathud isopod larvae on coral reef teleosts and elasmobranchs were quantified at Lizard and Heron Islands (Great Barrier Reef), and Moreton Bay, Australia. The relationship between gnathlid abundance and host size was examined across and within species. Of the 56 species examined. 70 % had gnathiids, with counts ranging from 1 to 200 per fish and the elasmobranchs hav- ing the highest numbers. Pomacentrids rarely had gnathiids. In contrast, most labrids had gnathiids. Gnathiid abundance was positively correlated with host size in the species Chlorurus sordidus, Ctenochaetus stnatus, Hernigyrnnus melapterus, Siganus dollatus, and Thalassorna lunare, but not for Scolopsis b~lineatus.Mean gnathlid abundance per host species also correlated with host size across species, even after controlling for the potential confounding effects of uneven sampling effort and host phylogeny Thus host size explains much of the intraspecific and interspecific variation In gnathiid abundance on fish.

Twenty-two reciprocally monophyletic sister- species pairs were identified: 64% were allopatric, and the remainder were sympatric. Age of divergence was similar for allopatric and sympatric species pairs. Sympatric sister pairs displayed greater divergence in morphol- ogy, ecology, and sexually dimorphic colour patterns than did allopatric pairs, suggesting that both genetic drift in allopatric species pairs and ecologically adaptive divergence between members of sympatric pairs have played a role in diversification. Basal species typically have small geographical ranges and are restricted to geographically and ecologically peripheral reef habitats. We found little evidence that a single dominant process has driven diversification, nor did we detect a pattern of discrete, sequential stages of diversification in relation to habitat, ecology, and reproductive biology. The evolution of Chlorurus and Scarus has been complex, involving a number of speciation processes.

The daily periodicity of microincrements forrned with the sagittal otoliths of these two spceies has been validated by oxytetracycline marking in previous studies. These validation studies have come from fishes within three regions of the Pacific (eastem, central and western tropical Pacific).

National Prioritization of Key Vulnerable Reef Fish Species for Fiji, for Targeted Research
National prioritization of key vulnerable reef fish species for Fiji, for targeted research Coral reef fish and invertebrates sold at the Suva market. Photo by: Sangeeta Mangubhai/WCS Introduction The majority of Fiji’s population is coastal and therefore highly reliant on inshore fisheries for their subsistence and local economic needs (Hunt 1999). At least 33 percent of all animal protein consumed in Fiji comes from fish, and subsistence and artisanal fisheries contribute at least US$59.1 million to Fiji’s annual GDP (Gillett 2009). There is growing concerns for the impacts of present day harvesting rates and methods, especially for vulnerable fish and invertebrate species in Fiji. This is resulting in a progressive decline in fish belonging to higher trophic (feeding) groups, a pattern that is termed “fishing down food webs” (Pauly et al. 1998). Coral reef fish vary in their vulnerability to fishing pressure, and how well they can recover, if fishing is stopped or significantly reduced. Recovery potential relates to the rate at which a species can replace the individuals that are lost to natural mortality and to fishing. In general, the medium to larger carnivorous fish high in the food chain are thought to be more vulnerable to fishing (e.g. groupers) requiring in decades to recover, while smaller fish (e.g. herbivores such as rabbitfish) are thought be less vulnerable (Abesamis et al. 2014). Certain life history characteristics of fish species together can be good predictors of vulnerability at the population level to fishing pressure, including: (a) maximum size; (b) body growth rate; (c) lifespan; (d) natural mortality rates; (e) age at maturity; and (f) length at maturity (Abesamis et al.
