Determining species diversity and functional traits of beetles for monitoring the effects of environmental change in the New Zealand alpine zone

Alpine invertebrate populations are expected to be highly sensitive to a changing climate because temperature plays an important role in their development, reproduction, and survival. However, high levels of rarity and endemism make it particularly challenging to measure climate effects on this grou...
