Abstract
Reproductive phenology in relation to fire and substrate in coastal Heath near Lancelin, Western Australia
Highlights
The reproductive phenology of species is one of the key components of community function, being integral to continuation of the species and having ramifications beyond any one particular species if pollinators, seed/fruit dispersers and propagule predators are involved (e.g. Rafferty & Nabity 2017)
Two questions were addressed - how is reproductive phenology affected by time since fire and do communities on different substrates under the same climate have different reproductive timing? In five sites with a range of fire histories differences were observed in both within-year reproductive patterns and total reproductive performance
Data on the intensity of flowering and fruiting were obtained for 162 species which occurred within site quadrats
Summary
The reproductive phenology of species is one of the key components of community function, being integral to continuation of the species and having ramifications beyond any one particular species if pollinators, seed/fruit dispersers and propagule predators are involved (e.g. Rafferty & Nabity 2017). In tropical areas seasonality is important and phylogenetic relationships seem to be strongly correlated with time of flowering within seasons (Wright & Calderon 1995). Within Mediterranean climate regions flowering may be strongly seasonal but phylogenetic constraints are less apparent While most Mediterranean climate regions are strongly seasonal it is usually water not temperature that is the main environmental factor influencing community function Overlaid on this climatic skeleton is the influence of frequent fire to which phenological patterns of some species have developed Overlaid on this climatic skeleton is the influence of frequent fire to which phenological patterns of some species have developed (Pignatti & al. 2002; Pyke 2017)
