“…The results from this study indicate that overall taxonomic richness and diversity, as well as the relative abundance of many reef-associated fishes, were generally highest for habitat types with the greatest relative vertical relief (e.g., ledges and fragmented hard bottom). These results largely corroborate the notion that, for many reef-associated taxa, overall diversity and species abundance are generally higher on high-relief reef habitats (Sluka et al 2001;Gledhill and David 2004;Koenig et al 2005;Harford et al 2016;McLean et al 2016). Given its importance as a correlate of abundance and reef-fish assemblage structure, vertical relief in some measure will be essential in developing an optimal habitat-based sampling strategy.…”

“…; McLean et al. ). In the present study, the relief ranged from 0.2 to 4.0 m in the habitat types that were characterized by notable vertical relief (e.g., fragmented hard bottom and ledge habitat), although pinnacles of 10 m or more occurred along the eastern Gulf of Mexico shelf break and in several artificial habitats (Keenan et al.…”

Increasingly restrictive management regulations have greatly reduced the utility of fishery‐dependent data for characterizing temporal changes in the abundance of managed fish populations, so fishery‐independent data are becoming more important for the accurate assessment of stock status. A notable downside to fishery‐independent data is the high cost of conducting surveys, and efforts to maximize survey efficiency are critical given ongoing reductions in agency funding. We conducted a pilot study to explore the utility of classifying side‐scan‐sonar mapping data to provide a practical a priori characterization of reef habitat in the eastern Gulf of Mexico. An analysis of side‐scan‐sonar mapping data identified five distinct reef habitat types (low‐relief hard bottom, mixed hard bottom, fragmented hard bottom, ledges, and potholes) that were subsequently sampled with stereo baited remote underwater video (S‐BRUV) arrays and trap‐mounted GoPro cameras. The permutational analysis of variance indicated that the assemblage structure of reef fish differed significantly (P < 0.01) among all of the pairs of habitats except ledges and fragmented hard bottom; assemblage structure did not differ among cameras (P = 0.45). Overall species richness and diversity were significantly higher in the habitats with greater vertical relief, as were the abundances of several economically and ecologically important reef fishes, although many taxa were observed across all of the habitat types. Benthic habitats that are identified from side‐scan‐sonar mapping data are important determinants of reef‐fish assemblage structure and may prove to be useful as a stratification scheme for reef‐fish surveys, although additional research is necessary to explore the transferability of these results to the rest of the eastern Gulf of Mexico.

“…In order to test the predictions of earlier spatial studies (e.g., Barley et al, 2017b;Meekan, Cappo, Carleton, & Marriott, 2006;Ruppert et al, 2013), we compared both the pre-and postrecovery of communities of mesopredatory fishes at Ashmore Reef to other nearby reefs in the region that are either currently being fished (the Scott Reefs) and have low numbers of sharks or have been protected for almost three decades (the Rowley Shoals) and have relatively "pristine" predator communities. As habitat also influences reef fish communities (Darling et al, 2017;Fitzpatrick, Harvey, Heyward, Twiggs, & Colquhoun, 2012;Friedlander & Parrish, 1998;McLean et al, 2016;Valdivia et al, 2017) and likely drives predatorprey interactions (Ritchie & Johnson, 2009), we compared changes occurring in communities of mesopredatory fishes through time in both reef and near-reef environments at Ashmore Reef. Contrasts between these habitats may be particularly important given the growing evidence that reefs sharks and other predatory fish species can consume non-reef-based prey (Frisch, Ireland, & Baker, 2014;Frisch et al, 2016;McCauley et al, 2012).…”

The recovery of communities of predatory fishes within a no‐take marine reserve after the eradication of illegal fishing provides an opportunity to examine the role of sharks and other large‐bodied mesopredatory fishes in structuring reef fish communities. We used baited remote underwater video stations to investigate whether an increase in sharks was associated with a change in structure of the mesopredatory fish community at Ashmore Reef, Western Australia. We found an almost fourfold increase in shark abundance in reef habitat from 0.64 hr−1 ± 0.15 SE in 2004, when Ashmore Reef was being fished illegally, to 2.45 hr−1 ± 0.37 in 2016, after eight years of full‐time enforcement of the reserve. Shark recovery in reef habitat was accompanied by a two and a half‐fold decline in the abundance of small mesopredatory fishes (≤50 cm TL) (14.00 hr−1 ± 3.79 to 5.6 hr−1 ± 1.20) and a concomitant increase in large mesopredatory fishes (≥100 cm TL) from 1.82 hr−1 ± 0.48 to 4.27 hr−1 ± 0.93. In contrast, near‐reef habitats showed an increase in abundance of large mesopredatory fishes between years (2.00 hr−1 ± 0.65 to 4.56 hr−1 ± 1.11), although only smaller increases in sharks (0.67 hr−1 ± 0.25 to 1.22 hr−1 ± 0.34) and smaller mesopredatory fishes. Although the abundance of most mesopredatory groups increased with recovery from fishing, we suggest that the large decline of small mesopredatory fish in reef habitat was mostly due to higher predation pressure following the increase in sharks and large mesopredatory fishes. At the regional scale, the structure of fished communities at Ashmore Reef in 2004 resembled those of present day Scott Reefs, where fishing still continues today. In 2016, Ashmore fish communities resembled those of the Rowley Shoals, which have been protected from fishing for decades.

“…We used likelihood ratio tests to evaluate the significance of model parameters, and adjusted p-values for multiple comparisons (Benjamini & Hochberg, 1995;Neyman & Pearson, 1933). To aid interpretation of model results, we assessed the relative support for each predictor by summing the AIC weights of all models including that term (Burnham & Anderson, 2002;McLean et al, 2016). We generated all figures using the package "ggplot2" in R (Wickham, 2009).…”

Aim We use publicly available data to assess the influence of ocean basin, various biological traits and sea surface temperature on biogeographic range extent for temperate, continental shelf fish species spanning 141 families. Location Coastal waters of the temperate Northern Hemisphere. Taxon Teleost Fishes (Infraclass Teleostei). Methods We assess the relationship between species range extent and depth range, maximum body length, schooling behaviour and use of multiple habitats for 1,251 species of northern, temperate, continental shelf fishes in different basins (Atlantic vs. Pacific) and margins (east vs. west) using linear mixed‐effect models with family and genus as nested random effects. We further assess the relationship between species range endpoint distribution and latitudinal temperature gradient using generalized linear models. Results We found strong positive relationships between the number of species northern range endpoints and the steepness of the latitudinal sea surface temperature gradient on the western margins of the Atlantic and Pacific Oceans, but no relationship on the eastern margins of these ocean basins. The strongest predictors of range extent in our global model are ocean basin/margin and depth range. Maximum body length, schooling behaviour and use of multiple habitats are also significant predictors of range extent in the global model. The factors influencing range extent differ by basin and margin. Main conclusions There are broad differences in patterns of species range extent and distribution of species ranges among basins/margins. These differences appear to be driven in part by variation in latitudinal water temperature gradient between basin margins. Our data suggest that sharp latitudinal temperature gradients may pose a barrier to dispersal and range expansion along the western margins of the Atlantic and Pacific Oceans, but not necessarily on the eastern margins. Our work also suggests that several post‐settlement traits may be associated with range extent either globally or in some temperate basins.
