Table 3. Results of Poisson GLMM for species richness recorded in BRUV deployments.
Factor | Co-efficient | Std Error | df | t-value | p-value |
Depth | −0.277 | 0.067 | 36 | −4.1489 | 0.0002 |
Mixed Habitat | 0.330 | 0.092 | 36 | 3.575 | 0.0010 |
Reef Habitat | 0.382 | 0.121 | 36 | 3.169 | 0.0031 |
Predictor variables have been scaled and centered and co-efficients are on the scale of the link function (log). Spatial clusters introduced as part of the sampling design were included as a random effect and the effects of habitat type (sediment, mixed or reef) are presented relative to sediment habitat.
