Modelling the flowering of four eucalypts species via MTDg with interactions

Abstract

Phenological indicators (e.g. date of first and last flowering, first arrival of migrating birds) are used as proxies of global climate change (Parry et al. 2008, Hudson et al. 2005; Root et al. 2003). Long-term (1940-1971) synchrony of four Eucalyptus species was recently quantified mathematically at the populationlevel (Keatley et al. 2004, Kim et al. 2008). Recently Hudson et al. (2009) has identified upper and lower temperature thresholds for E. leucoxylon flowering and showed that E. leucoxylon flowering is influenced predominantly by minimum temperature whose effect is highly non-linear. Keatley et al. (2002) reported that changes in temperature are likely to translate to changes in fl..
