BES Poster Presentation

Thanks for checking out my poster at BES Festival of Ecology, 2020!

My name is Suz Everingham, I’m from Sydney, Australia and I’m JUST about to hand in my PhD thesis on plant responses to climate change. The research presented in my poster was part of one of my thesis chapters. I looked at over 40 species flowering time including some of these pretty plants:

I tested overall shifts in flowering time using herbarium speciments, historic field and modern field data. These records came from the Northern Sydney Region (see the map below) and there were a total of 2105 records from 1842-2018 (see histogram of the distribution of records over the years).

Distribution of the records across the years (from 1842-2018). Note that the big spike around 2010-2011 and again in 2018 is due to the high number of field records collected by myself and co-authors.

I found really mixed results – some species flowered earlier in the year, some later, and some showed no singificant trend!

I’m now testing whether there is difference in flowering time shifts for native species compared to non-native species. and also if there is an effect of the growth form or phylogeny of the species on how much flowering time shifted. I hope to share these next results with you soon!

Likewise, there is limited data on photoperiod for these species but this could play a role in controlling flowering time.

Thanks for reading! You’ve now landed on my website, where you can check out my other research and also some of my blog posts about academic and scientific life.
