Pollen DNA metabarcoding identifies regional provenance and high plant diversity in Australian honey.

Accurate identification of the botanical components of honey can be used to establish its geographical provenance, while also providing insights into honeybee ( L.) diet and foraging preferences. DNA metabarcoding has been demonstrated as a robust method to identify plant species from pollen and pollen-based products, including honey.

Speleothem growth intervals reflect New Zealand montane vegetation response to temperature change over the last glacial cycle.

Flowstone speleothem growth beneath Mount Arthur, New Zealand shows a clear relationship to vegetation density and soil development on the surface above. Flowstone does not currently form beneath sub-alpine Nothofagus forest above ca. 1000-1100 m altitude but U-Th dating shows it has formed there during past intervals of warmer-than-present conditions including an early-mid Holocene optimum and the last interglacial from ca.
