What's up in research?
Published Saturday July 8, 2006 · Permalink
It has been a log time without writing about research. New country, new city, new job. In addition, consulting and professional service. Last but not least, family and friends come first: the end result is very little time to blog and even less for writing about research.
So, what am I doing at the moment? Simple, trying to figure out areas where I am not hitting diminishing returns too quickly. For example, estimating two hundred variance components is too rich, if we can do the job with ten. The practical return from all the additional works tends to zero: we are not making much of a difference. So, what’s the point? Yes, I can publish that, but who cares?
From a practical point of view, the real issue for me is on what is affecting competitiveness in a big way. Forestry is a long term endeavour, and the longer the rotation the higher the risk. From that point of view, extending rotation because radiata pine wood quality is not good enough borders on the stupid. Doh, of course is crappy wood; answers:
- Use something else or is there life beyond radiata pine?
- Select and breed for trees that have decent (I do not mean good) quality.
So, what are my current obsessions?
- Profitable shorter rotations. What are the limiting factors (hint: crappy wood quality, small size pieces and scale of the operations) to make this happen?.
- Very early selection of adequate trees. Notice emphasis: selection does not to be perfect to be useful. Adequate selections at age two is much better than good selections at age ten years.
- Why do trees grow the way they do in wood properties? Why do trees choose different strategies that have such dramatic differences in wood quality?
- Rapid turn-over breeding strategies. Are we still taking fifteen years for a breeding cycle? It is 2006! Can’t we do any better?
There is an obvious quantitative void in my obsessions, I know. But I am going back to attempting to understand some basic processes before I embark in more number cruncing. Despite of this, I am also interested (but not obsessed) in the following problems:
- Simulation of breeding strategies. I have a project working on this topic starting in October this year.
- Mate allocation and population structure. Trying to show that we can get rid of sublines and other artificial groupings when using sensible mating policies.
- Large scale genetic evaluation: how simple is simple enough? My way to help having frequent genetic evaluations.
What else? I am involved in a couple of three projects with students, dealing with wood quality, breeding or both. I have a new Ph.D. student starting in August on the interaction of economics and breeding. Ah, I almost forgot: there is a large number of lectures coming my way, better look busy…
