Sediment‐stressed reefs over the past 420 Myr

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.
