1 Untangling interactions: do temperature and habitat fragmentation gradients simultaneously impact biotic relationships? by Poppy Lakeman-Fraser, and Robert M. Ewers Proceedings B Volume 281(1787): July 22, 2014 ©2014 by The Royal Society

2 Field site localities. Poppy Lakeman-Fraser, and Robert M. Ewers Proc. R. Soc. B 2014;281: ©2014 by The Royal Society

3 Temperature variation across latitude in New Zealand. Poppy Lakeman-Fraser, and Robert M. Ewers Proc. R. Soc. B 2014;281: ©2014 by The Royal Society

4 Interactive effects of habitat fragmentation (fragment area and edge effect) and temperature (along a surrogate gradient of latitude) on three trophic levels (plant: (a,b); herbivore: (c,d); parasitoid: (e,f)) across two biotic measures (density: (a,c,e); a...

5 The nature and magnitude of interaction effects among fragment area (A), distance to habitat edges (E) and temperature differences as represented by a latitudinal gradient of study locations (L) on three trophic levels: (a) the host plant M. excelsum, (b) t...
