PhD Chap1 done! With an all-star cast, I built a reproductive phenology dataset by integrating flowering and fruiting observations from as many sources as possible. The dataset covers: 255yrs, most Subtropical rainforests in Aus, and 915 species. doi.org/10.1002/ecog...
Spatial distribution of reproductive phenology observations in Australian subtropical rainforest flora for three time periods: (a) 1770–1970, (b) 1971–2000 and (c) 2001–2025. The mapped region spans from 21 to 35°S and 150 to 155°E.

Take home points for John Dwyer's talkTemperature niche of two tree species in relation to Brisbane's temperature now and the prediction for 2070. We want street trees to last 50+ years, so they need to be able to cope with future climates. Croton would be better suited in this instance.Graph showing temperature niche of species best able to cope with Brisbane's future temperatures, with Owenia venosa as the example.
