#IBC18 on Wednesday

All of Wednesday’s (a half-day) tweets in one post.

Great to see the #ibc18 delegates out and about the Gardens!

…and so is the blog. There’s a slight delay to today’s recap as I was asked to sort out a page for AoB at the IBC. Here it is. You can also read Tim Entwisle’s blog post on the conference so far. There’s also a reminder about tomorrow’s or possibly today’s meet up depending on which time zone you’re in and when your’re reading it.

#ibc18 plenary. Tetsuya Higashiyama on live cell analysis of plant fertilization… Is there anything we shouldn’t know about Arabidopsis?

July 26, 2011
Higashiyama: "rapid and drastic" evolution of genes involved in pollen tube attraction, possibly involved in species differentiation. #ibc18

Such difficult terrain. Higashiyama using every technology he can to see what really happens in angiosperm double fertilisation. #ibc18

Next we have Zander Myburg: The Eucalyptus grandis genome sequence.

@TimEntwisle to a phycologist they all look the same 🙂 #arenttheyonespecies? #ibc18 <= trees just a terrestrial unicellular algal colony?

All trees are immortal colonial organisms (see Hallé). RT @Jim_Croft #ibc18 <= trees just a terrestrial unicellular algal colony?

Myburg: 20 million hectares of eucalypts planted around the world. More popular than the Wollemi Pine! #ibc18
TimEntwisle
July 26, 2011
Myburg "There are a lot of genes and they are in a linear order" – not a trivial statement, apparently. #ibc18
TimEntwisle
July 26, 2011
I’m sure the last slide (Myburg) was what I get when I defrag my computer – a eucalypt genome? #ibc18

Some unlinked scaffolds still to be incorporated into chromosomes – Myburg #ibc18

great data showing burst of retrotransposon activity giving larger size of E. grandis genome – 10% of genome. #ibc18

I’ll be talking about similar study of differences between Brassica sp. tomorrow – hope you all understood Myburg’s dot plots. #ibc18

after a morning of making wood and double fertilization, it’s time for coffee. Bet you wish you were at #ibc18 now, don’t you?

After a break in which I’ll briefly plug Green love talks; cell–cell communication during double fertilization in flowering plants by Tomokazu Kawashima and Frederic Berger in the open access journal AoB PLANTS, it’s time for the keynote symposia, opening with Perspectives on climate change and adaptation.
Guy Midgley introducing perspectives on climate change and adaptation Keynote Session. #ibc18
TimEntwisle
July 27, 2011
Is it just me or is the term ‘natural experiment’ in relation to climate change one of the most scary and reckless things imaginable? #ibc18
Jim_Croft
July 27, 2011
Guy Midgley: CO2 levels – pushing soon towards those not seen since the eocene, a world very different to today. #ibc18
Pathh1
July 27, 2011
Midgley: ‘Ecosystems Uncertain’ = where climate rules (water & temp) don’t work well. It’s 33% of global biomes and fire is important #ibc18
TimEntwisle
July 27, 2011
Midgley on fire: "Saplings can spend decades stuck in a fire trap – escape to trees rare and episodic". #ibc18
TimEntwisle
July 27, 2011
Midgley growing trees at CO2 levels like those prior to when human industry led to 33% increase. "Startling results" on root biomass. #ibc18

#ibc18 keynote talk. midgley gets two rounds of laughter from the audience in one slide. impressive.

#ibc18. Guy Midgely. role of (subambient) CO2 in carbon allocation. Pre industrial African ‘Acacia’ root growth *much* less than now.
Jim_Croft
July 27, 2011
Midgley says we need to take more interest in the impact of high CO2 levels themselves and not just impact on climate. #ibc18

#ibc18. now, William Bond on environmental change and the rise of flowering plants in evolutionary time.
Jim_Croft
July 27, 2011
William Bond: "Fire is a charismatic mega herbivore". #ibc18
TimEntwisle
July 27, 2011
#ibc18 William Bond: "fire is cool" #phraseoftheday

William Bond: Bioboundaries occur over one or two metres; these are the evolutionary theatres where speciation occurs #ibc18

Bond: Mike Crisp et al (2009), phylogenetic biome conservatism with few clades crossing biome boundaries, for "dumb ecologists" #ibc18
TimEntwisle

#ibc18: Bond – woody plants increasing in S Africa and many other parts of the world. #ligninjuggernaut
Jim_Croft
July 27, 2011
Bond:Is the rise of angiosperms an ‘open ecosystem’ success story? They have attributes of weedy species. Fire? Dino(saur)turbation? #ibc18
TimEntwisle
July 27, 2011
#ibc18 Bond: during their initial spread in Cretaceous, angiosperms were ‘small’ and fast-growing. ‘Dinoturbation’ = stomped by a ‘saur.
Jim_Croft
July 27, 2011
Bond: angiosperms as the ultimate weeds and dinosaurs as dispersal agents? "Dinoturbation" my new favourite word. #ibc18
IBC11
July 27, 2011
Bond: Hard to model oxygen levels & fire over geological timescale. Cretaceous oxygen was 25% higher than now fires would spread more #ibc18
Pathh1
July 27, 2011
#ibc18. Bond: angiosperms created understory fuel at a faster rate than the conifers they replaced. Charcoal evidence of Cretaceous fires.
Jim_Croft
July 27, 2011
Bond: if we reach IPCC predictions we may be faced with "a world covered with dreary forests" – the Eocene Scenario! #ibc18
TimEntwisle
July 27, 2011
Thoughts on Bond & modelling. Must be feedback: more fires–>less O2–>less fires–>more O2 . How much O2 needed to burn all forests? #ibc18
Pathh1
July 27, 2011
Bond: forests widespread by Eocene. Analogue to present? #ibc18

Wendy Foden questioning the analysis of how many species will succumb to climate change and then, what do we do with this data? #ibc18
TimEntwisle
July 27, 2011
#ibc18. William Bond: Invasive species as an example of biodiversity innovation.

#ibc18. now, Wendy Foden on climate change susceptibility and adaptability.
Jim_Croft
July 27, 2011
Foden: Quiver Tree (Aloe dichotoma) declining by 80% in some areas, up by 100% in others, but not expanding into predicted new range #ibc18
TimEntwisle
July 27, 2011
#ibc18. Wendy Foden, climate driven changes in distribution of African Quiver Tree, Aloe dichotoma. Visible to the naked eye!

Foden: Analysis of species sensitivity, adaptability and exposure (eg sea level rises) shows Amazon at risk for birds and amphibians #ibc18
TimEntwisle
July 27, 2011
#ibc18 Wendy Foden: susceptibility = sensitivity + unadaptability + exposure. Global risk map based on birds, amphibians, corals.
Jim_Croft
July 27, 2011
Interesting (from Foden work) that priority areas for rare species not always same as for ‘sensitive/exposed/unadaptable’ species. #ibc18

#ibc18. For some reason, the Coral Triangle turns up in analyses of climate change risk/threat for corals. #surprisesurprise #wellbuggerme
