Idea about dinosaur relationship dates back to the scientific debates of the 1860s

(1) What are birds?

Thomas Huxley (1825 - 1895)

(1) What are birds?

Huxley noticed five things about birds

• Fluffy body covering

• Birds can fly (bipinate feathers) +

Bi d b d h i • Birds brood their nests

• Birds take care of their young

• Birds have hollow bones (air sac system) +• Birds have hollow bones (air-sac system) +

“Barrington provides us with a baseline from which to track

changes in Irish birds over the last 120 years”

(Prof. Tim CroweUniv Cape Town)

• > 5,000 records of Irish birds and co. (700 species)• > 10 years data (1886 - 1899)• complete wings and legs• complete wings and legs• measurements, body mass, wing length• migratory and non-migratory species

How does this position UCD globally?

• Very little current work in this area: data resolution issue

Limited examples:• Predicting areas of biodiversity risk/management (Lee & Jetz 2008 Proc Roy Soc)• Identification of phylogenetic distribution of threatened UK birdsd a o o p y og d s bu o o a d U b ds(Thomas, G. 2009. Proc Roy Soc.)

• We have unique data: time-resolved, geographically constrained

• We are a major player in Evolutionary Biology:(www ucd ie/bioenvsci/research/evolution htm)(www.ucd.ie/bioenvsci/research/evolution.htm)

Conclusions & prospectus:

• (1) Birds are dinosaurs and have a deep evolutionary history

• (2) Because of their biology, birds are sensitive indicators of climate change

• (3) Two examples of current research, one that is (3) Two examples of current research, one that is uniquely Irish and relevant

• (?) Skeletal pneumaticity was important in avian evolution

• (?) Historical data can be used to inform the • (?) Historical data can be used to inform the present, and perhaps make future predictions

(4) Lessons for Ireland

• We can contribute to the climate change debate• We can contribute to the climate change debate

• Evolutionary biology underpins climate responses

• We have access to unique data (‘lab Ireland’)We have access to unique data ( lab Ireland )

• Stimulate research in all areas

• Get young people interested in science

• Graduate programmes in areas like evolution, palaeontology and climate change biology

‘prevailing scientific dogma can be an impediment to innovative ideas’(see for e.g. Nicholls 2009 Nature Darwin 200: A flight of fancy)

Key UCD Message

• The Innovation Imperative: Productivity growth in the Irish economy has slowed to close to zero. The only way to rediscover productivity growth and be able only way to rediscover productivity growth and be able to sustain it is by innovation and the embedding of the knowledge society.

• The Energy and Climate Change Imperative: We have hugely demanding energy and emission reduction obligations – the only way to meet them is through the use of markets and innovation.

• The Earth Systems Institute response to these imperatives We will be an engine showing how to imperatives - We will be an engine showing how to use research and innovation – smart technology and smart policy - to regain competitiveness and productivity generate jobs and meet our energy and productivity, generate jobs and meet our energy and climate change obligations
