Tuesday opened at the Congress and twitterers appreciated that improvements were made.

The day opened with Dr Gerard Oostermeijer: Integrating genetic and ecological data in plant conservation
Gerard Oostermeijer – integrating genetic & ecological data in plant conservation = translating models to on-ground actions #ibc18

Gerard: Plant conservation biologist needs to be jack of all trades #ibc18 Conservation involves on-ground citizen scientists too.

Distribution mapping is bad predictor: by the time pop decline is monitored its almost too late. Don’t fisheries people say this too? #IBC18

#ibc18 Oostermeijer. easy to get funding for on-ground action, not so for e.g. population viability analyses, etc.
Jim_Croft

Oostermeijer: Citizen botanists critical to research & monitoring, but not (along with scientists!) effective early-warning systems. #ibc18

Primula in Netherlands: only 6 populations left, one has pin morph only left. But there is hope with some seedling recruitment. #ibc18

Liparis is pioneer species. But responding to soil acidity not open-ness of habitat. Dynamic habitat means pops are short-lived #ibc18

Oostermeijer: Distribution of plants between islands in Netherlands may be due to "botanists with muddy boots". #ibc18

Decision tree: Often genetic rescue is necessary, but there is fear of outbreeding depression (Franham et al. 2011) #ibc18

Conservation/restoration work> external factors (habitat quality) important but Intrinsic factors are also critical to success. #ibc18
Pathh1
July 25, 2011
#ibc18 Oostermeijer most conservation actions based on belief in importance of external factors, but many are intrinsic to the population.

The followed Plant modelling by Professor Przemyslaw Prusinkiewicz.
#ibc18 plenary. Przemyslaw Prusinkiewicz: Plant modelling. Gross morphology. Principle of hierarchical self organization.
Jim_Croft
July 25, 2011
Przemyslaw Prusinkiewicz: Branching the one of most conspicuous feature of plants – how does such complexity come about? #ibc18
TimEntwisle
July 25, 2011
Prusinkiewicz: Basic Ulam (1962) model of branching: if enough space, grow; if not enough space, don’t grow. #ibc18 Me: good life rule!

To plug his paper again, Towards aspect-oriented functional–structural plant modelling is online at Annals of Botany. We also have a standard policy if you want to blog about an AoB paper we can provide free for you. As far as we’re concerned botanical bloggers are science reporters. If you want to blog about a lot of research, the Research Blogging site can help you get more readers for your posts.

And now on with the sessions.

Peter Crane heads off one of the Keynote Sessions today ‘The past, present and future of plant diversity’ #ibc18

#ibc18 Keynote. Peter Crane: patterns in the history of plant diversity. history of angiosperm fossils, x-ray & electr. flower dissections.

Why study plant fossils? Peter Crane lets us know in no uncertain terms, with review of amazing new understanding since IBC1999 #ibc18

Crane: Early cretaceous (136-108 mya) with bits and pieces of angiosperms – many families and orders. Aroids recently identified.#ibc18
TimEntwisle
July 26, 2011
#ibc18 Crane: the Cretaceous is a very long period (80 m yrs). A lot happened on the angiosperm scene, basal and eu- dicots.
Jim_Croft

#ibc18. Crane describing ‘comfortable consistency’ between the phylogeny of current angiosperms and palaeontological record.
Jim_Croft
July 26, 2011
New understanding from Mesofossils (lignified/carbonized), non-angiosperms, techniques, phylogentic framework, flowers, missing taxa. #ibc18

July 26, 2011
#ibc18 Crane – now the hard stuff – what to do about missing data in the record? especially at the base of the tree, the early divergences.
Jim_Croft

Crane: fossils give us sense of order of synapomorphies but still problems in flower development, need more on structures & full data #ibc18

Lughadha: Most new species of plant likely to be in areas already identified as biodiversity hotspots, or alternatively in herbaria! #ibc18
TimEntwisle
July 26, 2011
I guess herbaria are *the* (taxon) diversity hotspots now. A shame they are mostly dead (a nod to seeds and spores). #ibc18
TimEntwisle
July 26, 2011
@TimEntwisle it seems identified hotspots for undescribed species were not as high in SE Asian rainforest…I am surprised by that.#ibc18

Mobile small RNA may also affect gametophye – Voinnet #ibc18

Voinnet: consequences. Small RNAs reach meristem, de novo methylate meristem DNA & pattern transmitted to new growth –> epivariant #ibc18

Dynamic system allows smallRNA pool activation, moves through plant, adaptation in real time, also transmitted to next generation #ibc18

Next came an ePoster session – which is new to me. There’s nothing to see here alas.

Rapid Fire ePoster Session: "Photography & video recording are not allowed during presentations." < Wha? Why?? #ibc18
