Predicting Extinction Risk:The Importance of Life History and Demography

Mon, 28 Jul 2014 14:46:17 +0000

The changing climate is no longer simply a concern for the future, it is a reality. Understanding how the biodiversity that we share our planet with will respond to climate change is a key step in developing long-term strategies to conserve it. Recent research by UCL CBER’s Dr Richard Pearson identifies the key characteristics that [...]

It Pays to Be Different:Evolutionary Distinctiveness and Conservation Priorities

Tue, 15 Jul 2014 13:15:25 +0000

The world is currently experiencing an extinction crisis. A mass extinction on a scale not seen since the dinosaurs. While conservationists work tirelessly to try and protect the World’s biodiversity, it will not be possible to save everything, and it is important to focus conservation efforts intelligently. Evolutionary distinctiveness is a measure of how isolated [...]

Synthetic Biology and Conservation

Mon, 07 Jul 2014 16:20:18 +0000

Synthetic biology, a hybrid between Engineering and Biology, is an emerging field of research promising to change the way we think about manufacturing, medicine, food production, and even conservation and sustainability. A review paper released this month in Oryx, authored by Dr Kent Redford, Professor William Adams, Dr Rob Carlson, Bertina Ceccarelli and CBER’s Professor [...]

Measure Twice, Cut Once: Quantifying Biases in Sexual Selection Studies

Wed, 25 Jun 2014 10:44:30 +0000

Bateman’s principles are conceptually quite simple, but form the basis of our understanding of sexual selection across the animal kingdom. First proposed in 1948, Bateman’s three principles posit that sexual selection is more intense in males than in females for three reasons: 1) males show more variability in the number of mates they have (mating [...]

Technology for Nature?

Mon, 16 Jun 2014 13:23:54 +0000

Many of our greatest technological advances have tended to mark disaster for nature. Cars guzzle fossil fuels and contribute to global warming; industrialised farming practices cause habitat loss and pollution; computers and mobile phones require harmful mining procedures to harvest rare metals. But increasingly, ecologists and conservation biologists are asking whether we can use technology [...]

Obituary: Professor David Wilkie, born 6th August 1923, died 3rd March 2013

4 April 2013

A picture of Ian as a young handsome RAF pilot

My colleague David Wilkie who died recently at the age of 89 was an extraordinary and endearing character. As an undergraduate at Glasgow University he played football for Queens Park, then an amateur club in the professional Scottish league, having previously represented Scotland as a schoolboy. David's studies were interrupted in 1942 when, at the age of just 19, he volunteered for service in the RAF.

Following training on Spitfires in South Africa David was transferred to Burma where he flew Hurricanes in the war against Japan. When the war ended he remained in the Far East where he flew Dakotas and DC3's and helped evacuate prisoners of war from the infamous Changi prison in Singapore. During this period David was the personal pilot to Air Officer Commanding (AOC) RAF Burma, Hugh Saunders (later Air Chief Marshall Sir Hugh Saunders). Pilot Officer Wilkie returned to Scotland in December 1946 saying that he had flown every day for four years and never wanted to fly again. He never did.


After completing his undergraduate studies David remained in Glasgow where he joined the laboratory of the distinguished geneticist Guido Pontecorvo who was then engaged in the fine structure mapping of genes in the the ascomycete fungus, Aspergillus nidulans. His PhD complete, David was appointed in 1954 to a Lectureship in the Department of Botany, University College London where he was to remain for his entire academic career.

At UCL David initially continued research on the genetics of Aspergillus showing among other things that the mutagenic wavelength of UV light was 260 nm rather than 280 nm and, thus, was inducing changes in nucleic acid and not protein. In 1959-1960 a Rockefeller Foundation Visiting Fellowship to the Genetics Department of the University of Washington, Seattle signalled a change of research direction. In Seattle David came under the 'inspired guidance' (his words) of Herschel Roman and Don Hawthorne who were among a small group of geneticists who foresaw the enormous research potential of working with a single celled organism, the budding yeast Saccharomyces cerevisiae. Over the next ten years David's work explored the possibility that, in addition to genes located on the chromosomes in the nucleus, yeast also possessed genes in the mitochondrion, the organelle that generates most of the cell's energy. This was a risky, even foolhardy, research venture in the early 1960's but with typical patience and resourcefulness David was able to show that not only did such genes exist, but also that they were linked together on a small mitochondrial 'chromosome.' By 1963 the work had advanced sufficiently to publish a monograph entitled The Cytoplasm in Heredity which was the standard reference in this area for a number of years.


Mitochondria remained the focus of David's research for the next 30 years (he often described himself as a 'mitochondriac'). From the 1970's his thoughts increasingly turned to the role of mitochondria in cancer; in particular as targets for chemotherapy. Once again, this was a controversial topic albeit one that has received increasing credence as more and more is understood about these fascinating organelles. Throughout David's career at UCL he was a much loved undergraduate teacher, a kind and generous mentor to postgraduate students and a patient and meticulous examiner.  David retired from UCL in 1988 but carried on his research a couple of days a week in a corner of my lab. My students loved having him around; perhaps in part because there was always shortbread for afternoon tea!


I feel honoured to have shared my working life with such a distinguished scientist and such a remarkable man.

Emeritus Professor of Cell Biology, UCL
