Promised self I won’t cry, am a big Congress now. RT TimEntwisle #ibc18 Last day, final talks, closing session, farewells & tearful tweets..
IBC11
July 29, 2011
It is indeed the last day of the International Botanical Congress. There’s no plenary session this morning and the schedule of symposia is light with a mere 15 parallel sessions. As before I’ll try to collate the tweets by talk.
An early morning session on algae and how they are responding to environmental change, and dealing with it. Wow. #ibc18
TimEntwisle
July 29, 2011
John Raven: Marine phytoplankton main contributors to algal productivity and about half the total carbon fixed in biosphere. #ibc18
TimEntwisle
July 29, 2011
J Raven: CO2 up, carbonate in water goes down, and calcification (algal walls) goes down (more so if temperature goes up). Not good. #ibc18
TimEntwisle
July 29, 2011
J Raven: marine algae will move to higher latitudes to cope with CO2 induced ocean changes or if run out of latitude, evolve (if can) #ibc18
TimEntwisle
July 29, 2011
J Raven: Globally phytoplankton in warmer ocean have less N and P but more light, could offset stimulation by CO2. #ibc18
TimEntwisle
July 29, 2011
J Raven: Putting aside carbon, phosphorus, nitrogen, temperature and light, iron may be limiting. Or may not. #itainteasy #ibc18
TimEntwisle
July 29, 2011
J. Raven: Some +ve, some -ve, regarding evolutionary adaptation: some diffs in strains and ability to tolerate high tem. #ibc18
TimEntwisle
July 29, 2011
Last session: rebuilding botanical capacity. Dealing with a pandemic of plant-blindness. #ibc18
IBC11
July 29, 2011
First: Andrea Kramer on US Botanical Capacity Assessment Project. #ibc18
IBC11
July 29, 2011
Kramer: concern re: decline in botany since 1955. Study showing school children much more able to ID animals than plants. #ibc18
IBC11
July 29, 2011
Kramer: first challenge in defining boanical capacity. Overlap between education, research and management. #ibc18
IBC11
July 29, 2011
Kramer: precipitous decline in botany degrees vs general biology since c. 2000. Many unis have eliminated bot depts. #ibc18
IBC11
July 29, 2011
Kramer: US Bureau of Land Mgmt has 1 botanist per c. 4 million acres of land. #ibc18
IBC11
July 29, 2011
Kramer: survey of more than 1500 respondents who IDed themselves as working or studying in plant sciences. #ibc18
IBC11
July 29, 2011
Kramer: many respondents asking for field botany experience. A lot of courses no longer include it. #ibc18
IBC11
July 29, 2011
@IBC11 Student decline problem: botanical research underpins solutions to most of world’s problems: food, health, fuel, environment #ibc18

last morning of the #ibc18. Botanic Gardens and climate change session. Leif Schulman on European BGs and CC mitigation and adaptation.
Jim_Croft
July 29, 2011
#ibc18. Schulman. in the last 2-3 decades, conservation added to research, display and education as major function of botanic gardens.
Jim_Croft
July 29, 2011
Schulman: trend to urban ‘green roofs’ may introduce invasives, but may offer large reserve of biodiversity for conservation. #ibc18.
Jim_Croft
July 29, 2011
Pfiel: methods for detecting: Lineage sorting vs paralogy vs hybridisation.#ibc18
danieljmurf
July 29, 2011
Catriona Hurd: 35% of anthropogenic CO2 absorbed by oceans – good for us but no so good for marine organisms (change in acidity). #ibc18
TimEntwisle
July 29, 2011
Hurd: low ocean pH will cause algal and invertebrate skeletons to dissolve #ibc18
davidorlovich
July 29, 2011
Will leave ?@davidorlovich to track algae while I go and talk to Mr Marnie on @702sydney #ibc18

Hurd: stole a flume from Port Harrison #ibc18
davidorlovich
July 29, 2011
Roxi Steele @ #ibc18 # phylogenomics: costs for Illumina will soon compete with traditional DNA barcoding (100x data for 1-10x the cost)
JChrisPires
July 29, 2011
Hurd: In the short term, coralline algae can compensate for low pH by raising it in the boundary layer. Long term effect unknown #ibc18
davidorlovich
July 29, 2011
Hurd: the benthic film on abalone photosynthesizes, slightly pushing up pH in boundary layer #ibc18

Michael McKain @ #ibc18 – Origins of bimodal karyotype in Agavaceae, #plastome phylogenomics shows it evolved once, but how did it arise?
JChrisPires

Michael McKain #Phylogenomics & #transcriptomics detect ancient polyploidy shared by Agave and Hosta (and not in Chlorophytum)! @ #ibc18

Now: Alex Sumadijaya from Bogor on plant ID consistency. #ibc18
IBC11
July 29, 2011
Sumadijaya: big increase in demand for IDs from public over recent years. #ibc18
IBC11
July 29, 2011
Sumadijaya: six years of data, thousanfs of records, different patterns of demand for different families & genera. #ibc18
IBC11
July 29, 2011
Sumadijaya: dominant taxa brought for ID include Ficus, Cucurma, Zingiber, Syzygium & Piper i.e. economic pls. #ibc18

IBC11
July 29, 2011
Moraes: urgent need work in areas with agricultural pressure on huge biodiversity. Many areas not collected for decades or centuries. #ibc18
IBC11
July 29, 2011
Moraes: Brazil’s major exports are agricultural, developing economy. Difficult to reach and convince decision-makers. #ibc18
IBC11
July 29, 2011
Moraes: increasing nos of masters grads and doctorates in Brazil, but hard to find a job. (Brazilian brain drain.) #ibc18
IBC11
July 29, 2011
Moraes: need for Brazil to balance priorities inc. health, economic development and investment in science. #ibc18
IBC11
July 29, 2011
Moraes: various bodies who can contribute- Br Natl Centre for Flora Conservation, Atlantic Rainforest Pact, Brazilian Checklist etc. #ibc18

Erica Young: Algae that might save the world… First up, biofuels. #ibc18
TimEntwisle
July 29, 2011
Young: Traditionally microalgae in bioreactors – high maintenance, easily contaminated, require lighting and expensive to harvest. #ibc18

July 29, 2011
4 olympic swim pools could culture world’s cotton but feedstock/sterilization cost same as US oil @TimEntwisle: algae in bioreactors #ibc18
Pathh1
July 29, 2011
Young: Alternative is to cultivate algae in wastewater – contribute to water treatment and produce fuel. #ibc18
TimEntwisle
July 29, 2011
Young: Algae don’t naturally grow in monocultures so ‘algal consortia’ in yucky water [my term] good place to start for algal fuel. #ibc18
TimEntwisle
July 29, 2011
Young: Cladophora (big green alga) grows well in wastewater effluent/easy to harvest/ high nutrient uptake capacity/cleans water. #ibc18
TimEntwisle
July 29, 2011
Young: diatoms cover the Cladophora and they also provide other nice molecules, such as lipids. #ibc18
TimEntwisle
July 29, 2011
Young: Use of mixed algal biomass for fuel could help fund water treatment plants, particularly in poorer communities. #ibc18
TimEntwisle
July 29, 2011
Young: Don’t have luxury of excluding options for fossil fuel reduction: marine, freshwater, biofuels, lipids, cellulose…ALGAE#ibc18
TimEntwisle
July 29, 2011
Young: Ends with "Pond Scum can save the world, if we really want it to". #ibc18

Cornelia Lohne on reducing the climate footprint of a botanic garden. #ibc18 Berlin BG could sequester enough C for 300 cars/yr.
Jim_Croft
July 29, 2011
Lohne. Unfortunately the carbon sequestered in Berlin BG is more than offset by heating, lighting, use of peat. #ibc18
Jim_Croft

Beardall: Algae draw down carbon but also get into sulphur: DMSP produced by algae, released as DMS and sulphate, forms clouds… #ibc18
TimEntwisle
July 29, 2011
Beardall: "sloppy feeding [by algae] leads to release of DMS" (> sulphate > cloud condensation nuclei > clouds > reflects sunlight) #ibc18
TimEntwisle
July 29, 2011
Beardall: DMSP higher as salinity goes up but lower as temperature goes down. But in single cells; may not apply to population. #ibc18
TimEntwisle

Michael Kiehn (briefly fighting technology) "something like this should be expected when someone from Austria presents in Australia." #ibc18
Jim_Croft
July 29, 2011
Beardall: Conclusion: less DMSP production (at least in Gephryocapsa) as temps rise, less clouds, less reflection of solar radiation #ibc18
