Fire and seed dormancy: a global meta-analysis.

ABSTRACT:

Background and aims

Fire-released seed dormancy (SD) is a key trait for successful germination and plant persistence in many fire-prone ecosystems. Many local studies have shown that fire-released SD depends on heat and exposure time, dose of smoke-derived compounds, SD class, plant lineage and the fire regime. However, a global quantitative analysis of fire-released SD is lacking. We hypothesized that fire-released SD is more prevalent in fire-prone than in non-fire-prone ecosystems, and in crown fire compared with surface fire ecosystems. Additionally, we expected to uncover patterns in the relationship between fire cues and SD classes at the global scale that mirror those identified in local or regional studies.

Methods

In total, 246 published germination studies from 197
