Ecology

Dent, J. & Molles, L. (2016). Call-based identification as a potential tool for monitoring Great Spotted Kiwi. Emu, 116, 315-322. doi:10.1071/MU15079

What it's about:

This research has led to a 2020/2021 Verum Group project "Individual Recognition & Monitoring of Great Spotted Kiwi" led by Laura Molles. The study will hopefully pave the way for monitoring of the Great Spotted Kiwi population in a non-invasive manner, avoiding the need to capture the birds.    Email Laura Molles

Valderrama, S., Molles, L., Waas, J. & Slabbekoorn, H. (2013). Conservation implications of song divergence between source and translocated populations of the North Island Kōkako. Journal of Applied Ecology, 50, 950-960. DOI:10.1111/1365-2664.12094

What it's about:

This research investigated variation in song, and response to song, among source and translocated populations of the endangered North Island kōkako - combining together song, translocations, and conservation.    Email Laura Molles

Molles, L. & Vehrencamp, S. (2001). Songbird cheaters pay a retaliation cost: evidence for auditory conventional signals. Proceedings of the Royal Society of London, Series B 268, 2013–2019. DOI:10.1098/rspb.2001.1757

What it's about:

This research was an early and convincing demonstration of an important concept in animal communication.    Email Laura Molles

Geochemistry

What it's about:

Geochemists team up with an economist to identify bounding chemical and economic conditions that determine the applicability of passive and active mine water treatment options. Email James Pope and Dave Trumm

What it's about:

Realgar and gold precipitation processes usually occur at > 100 in geothermal systems – we identified these geochemical processes at ambient temperature in historic mine waste. Email James Pope and Dave Trumm
