To support ongoing marine spatial planning in New Zealand, a numerical environmental classification using Gradient Forest models was developed using a broad suite of biotic and high-resolution environmental predictor variables. Gradient Forest modeling uses species distribution data to control the selection, weighting and transformation of environmental predictors to maximise their correlation with species compositional turnov...

Rhodoliths are recognised as providing critical ecosystem services in nearshore systems through habitat provision. We tested the influence of rhodolith hosts and habitat on the diversity and composition of sessile and motile invertebrates found associated with two species of rhodolith. Investigations of cryptofauna were undertaken at three beds within the Bay of Islands, northern New Zealand. Lithothamnion crispatum , which wa...
