Weak global trade‐off between frost and drought resistance in trees

open access: yesNew Phytologist, Volume 249, Issue 2, Page 810-828, January 2026.
Summary Drought and frost stresses play important roles in determining species distributions, especially at range margins. Understanding how stress resistance traits interact to determine vulnerability to climate change is critical. We developed a large global database of published and new measurements of drought resistance (xylem embolism resistance ...

Palynological, tephra, and 14C records from southern Kaitoke, Great Barrier (Aotea) Island, New Zealand, since c. 30,000 cal. yr BP

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 1096-1114, December 2025.
ABSTRACT Here we present results of the last remaining three, unreported pollen and stratigraphic profiles from our previous investigations on Great Barrier Island from southern Kaitoke. The 14C and pollen data extend the island's previous maximum pollen‐vegetation date from c. 7000 cal. yr BP to close to the end of MIS 3 c. 30,000 cal. yr BP.

Environmental evolution of cover deposits on chemically distinctive bare ground, New Zealand: review and temporal contexts

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1120-1152, December 2025.
ABSTRACT Chemically distinctive features such as high salinity, low nutrient contents, and extremes of pH can limit the development of a vegetation cover on soil‐free bare ground. This study synthesises our previous work on the geoecology of numerous chemically distinctive bare sites in the South Island and adds a temporal component within the last ...
