Population dynamics of glow-worms

Te Papa researcher: Julia Kasper

This research investigates whether glow-worms from different geographic regions are genetically different from one other – by sampling glow-worms from across the country for genetic analyses, and by rearing larvae to adulthood for morphological analysis.

The outcomes will have fundamental scientific value to the study of the ecology of insects with restricted dispersal ability. This research is directly relevant for sustainable conservation management, to iwi and to ongoing management of glow-worm populations subject to tourism.
