Aim? The physiological requirements and tolerances of a species partially determine both its habitat preferences within a community and its broader geographic range. Therefore, we predicted that local ecology should be correlated with geographic distr . . .

In their recent comment in this journal, T. M. Blackburn and colleagues called into question the use of standardized partial regression modelling (also called path analysis and structural equation modelling) when null expectations for regression coeff . . .

A recent paper by Karels et al., 'The biogeography of avian extinctions on oceanic islands' (Journal of Biogeography, 2008, 35, 1106-1111), uses structural equation modelling to assess the causes of the number of island bird species driven extinct in . . .
