Gender Differences and a New Adult Eukaryotic Record for Upper Thermal Tolerance in the Desert Moss Syntrichia Caninervis

Abstract

1.Two Competing Hypotheses Relating to Thermostress Were Proposed to Understand Skewed Sex Ratios in Syntrichia Caninervis, a Reproductive Investment Hypothesis and a Wildfire Selection Hypothesis.2.Nearly All Shoots from Both Sexes Remained Viable (Regenerated in Culture) Following Exposure to 120 °C for 30 Min, Thus Setting a New Upper Thermotolerance Record for Adult Eukaryotic Organisms for a Minimum 30 Min Exposure Time.3.Males Regenerated Faster Than Females, Produced More Biomass, and Suffered Less Fungal Attack Than Females. Findings Support the Wildfire Selection Hypothesis. © 2008 Elsevier Ltd.
