Habitat Selection

The role of habitat selection versus species-sorting in shaping species distributions across a canopy cover gradient. Research conducted at Koffler Scientific Reserve (KSR). See French and McCauley (2018).

Canopy cover surrounding aquatic mesocosms limited the number of visits by adult dragonflies, but did not affect the survival of larval dragonflies. It is therefore likely that previously observed patterns of decreasing larval dragonfly diversity with increasing canopy cover (McCauley et al. 2008) are driven by the limited attraction of adults to closed habitats.

Movement Behaviour

Whether forests impose a barrier on dispersal by adult dragonflies to reproductive habitats. Research conducted at Koffler Scientific Reserve.



Community Recovery

The influence of landscape matrix conditions on the recovery of larval dragonfly communities following a drought. In collaboration with researchers through the Edwin S. George Reserve.
