Relative importance plots for boosted regression tree analysis of total large-bodied reef fish biomass (all species pooled) and presence/absence of key species.

, 2013
Species selection was based on maximum data density, and management and ecological importance. CAAB = Carcharhinus amblyrhynchos, LUBO = Lutjanus bohar, MASP = Macolor spp., TROB = Triaenodon obesus, NAHE = Naso hexacanthus, SCRU = Scarus rubroviolaceus,

Can denticle morphology help identify southeastern Australian elasmobranchs?

Journal of Fish Biology, Volume 104, Issue 6, Page 1848-1859, June 2024.
Abstract Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising dentine and enameloid. These structures vary across the body of an individual and between species, and are frequently shed and preserved in marine sediments.

Effect of zoning on shark abundance, Great Barrier Reef of Australia.

, 2014
The predicted abundance for (a, b) all shark species pooled, Carcharhinus amblyrhynchos (c, d, e), C. albimarginatus (f, g, h), Galeocerdo cuvier (i, j, k), and Triaenodon obesus (l, m, n) was examined across the range of hard coral cover (%), days since

Comparative assessment of eDNA metabarcoding and longline deployments for elasmobranch surveying across a large tropical marine park network

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 4, April 2024.
Abstract Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is “how do we collect relevant data on biodiversity and population trends to inform their design and measure success?” This question is particularly relevant for marine taxa that are ...

Environmental factors modulate the distribution of elasmobranchs in southern Mozambique

Frontiers in Marine Science
Investigating the spatiotemporal ecology of elasmobranchs is an important precursor to their effective management. Understanding long-term patterns in the movement and habitat use of threatened species can improve management plans so that they yield ...

Summary results of Poisson (P) and negative binomial (NB) regression models used to examine the effect of zoning (areas closed/open to fishing) on the relative abundance of sharks (2004–2010).

, 2014
The performance of P and NB models were compared using Akaike's information criterion (AIC) against nested models and significant differences were evaluated with maximum likelihood ratio tests (χ2 ...

Characteristics of the shark fisheries of Fiji [PDF]

, 2015
Limited information is available on artisanal and subsistence shark fisheries across the Pacific. The aim of this study was to investigate Fiji’s inshore fisheries which catch sharks.

Boosted regression tree (BRT) analysis: Optimal parameter settings, predictive performance, and relative influence of environmental variables on total large-bodied reef fish biomass and presence/absence of key species.

, 2013
Note: Total Biomass values were double-log+1 transformed to achieve pseudo-normality, species were analyzed based on presence/absence. Species selection was based on PRIMER BEST analysis, maximum data density, and management importance.
