Alan Pearse & Grant Hamilton have recently had a paper accepted for publication in Ecology and Evolution. This paper investigates the effect of spearfishing and habitat associations on the abundance of humphead wrasse (Cheilinus undulatus) and bumphead parrotfish (Bolbometopon muricatum). These fish are listed as Endangered and Vulnerable, respectively, on the IUCN Red List of Threatened species. The main results can be seen in Figure 2 below:
Figure 2: Average number of adult B. muricatum and C. undulatus per hectare by level of historical fishing pressure and reef strata. The error bars represent the upper bound of the 95% confidence intervals (Pearse et al., 2018).
