Abstract
Improved access to multibeam sonar and underwater video technology is enabling scientists
to use spatially-explicit, predictive modelling to improve our understanding of marine ecosystems.
With the growing number of modelling approaches available, knowledge of the relative performance
of different models in the marine environment is required. Habitat suitability of 5 demersal
fish taxa in Discovery Bay, south-east Australia, were modelled using 10 presence-only algorithms:
BIOCLIM, DOMAIN, ENFA (distance geometric mean [GM], distance harmonic mean [HM], median
[M], area-adjusted median [Ma], median + extremum [Me], area-adjusted median + extremum [Mae]
and minimum distance [Min]), and MAXENT. Model performance was assessed using kappa and
area under curve (AUC) of the receiver operator characteristic. The influence of spatial range (area
of occupancy) and environmental niches (marginality and tolerance) on modelling performance were
also tested. MAXENT generally performed best, followed by ENFA-GM and -HM, DOMAIN, BIOCLIM,
ENFA-M, -Min, -Ma, -Mae and -Me algorithms. Fish with clearly definable niches (i.e. high
marginality) were most accurately modelled. Generally, Euclidean distance to nearest reef, HSI-b
(backscatter), rugosity and maximum curvature were the most important variables in determining
suitable habitat for the 5 demersal fish taxa investigated. This comparative study encourages ongoing
use of presence-only approaches, particularly MAXENT, in modelling suitable habitat for demersal
marine fishes.
