Upper range limit establishment after wildfire of an obligate-seeding montane forest tree fails to keep pace with 20th century warming

Abstract

Aims How species respond to climate change at local scales will depend on how edaphic and biological characteristics interact with species physiological limits and traits such as dispersal. Obligate seeders, those species that depend on fire for recruitment, have few and episodic opportunities to track a changing climate envelope. in such cases, long-distance seed dispersal will be necessary to take advantage of rare recruitment opportunities. We examine recruitment patterns and seedling growth below, at and above the timberline of an obligate-seeding Australian montane forest tree (Eucalyptus delegatensis) after stand-replacing fire, and place these changes in the context of regional warmin..
