Excited to share the latest from the #eFLOWERproject: a morphospace study of angiosperm flowers led by Andrea López-Martínez and Marion Chartier!
Angiosperm flowers reached their highest morphological diversity early in their evolutionary history
nph.onlinelibrary.wiley.com/…
Morphological trait of different floral 🌼 modules evolve at different rates in #Ericales 🫐 and #angiosperms🌻.
We investigated how evolutionary rates compare among flower modules and how rates and floral disparity are connected.

The image shows the phylogenetic reconstruction of Ericales with the ancestral state reconstruction of the number of fertile stamens. Pies on the nodes show the most likely state at each node and the branches represent one randomly drawn stochastic map. The number of fertile stamens has three states shown in different colors: blue (1-5), yellow (6-10), green (>10).
In general, across Ericales and angiosperms the ranking from fastest to slowest evolutionary rates among floral modules is:
1. Androecium ♂️
2. Perianth 🌼
3. Gynoecium ♀️
2/n
Comparing rates with disparity (Chartier et al 2017), we found 3 ways they co-occur:
- fast evolution & high disparity
- slow evolution & high disparity
- slow evolution & low disparity
never fast evolution & low disparity.

Had a touching and inspiring time this morning at Yandel’ora on Dharawal Country celebrating #NAIDOCWeek by designing and making an ephemeral mural with all ABG staff. This place definitely has a magic to bring people together. @BotanicSydney
Where do fossil flowers fit in the angiosperm phylogeny? Here we provide some possible answers using a diversity of methods, including constrained and unconstrained MP, ML, and BI phylo analyses.
Now out in early-access view in @systbiol: doi.org/10.1093/sysbio/syad0…
New paper in @NewPhyt. Surely every Aussie plant species has been photographed at least once? Turns out a lot haven't! Of ~21,000 native species, 18% didn't have a field photo across 33 online resources. SE states are well-documented, WA has most gaps

I surveyed Wategora Reserve in western Sydney for 380 hours from 2020-2022, recording 1926 species. The reserve contains the critically endangered community Cooks River/Castlereagh Ironbark Forest.

Piece out from myself and Judy Friedlander in @ConversationEDU on citizen science demographics, the recent B&B BioBlitz for school kids, and tips for making good photographic observations of biodiversity (esp. for iNat)

With the @ASBS_botany conference coming to a close, I wanted to share with you the magnificent plant tattoos of plants real and not so real that are residing under the skin of some attendants. See all in the thread. Can you name the plants portrayed?
