Over the past few days, I had a chance to visit some great prairies to do some work on bison. Each prairie is grazed, but they have different histories and current management. When you look closely, the grasses ar...

Improvements on measuring drought tolerance. Just a quick note here on measuring drought tolerance. In the past, we were using a pressure bomb to determine a plant's water potential at which stomatal conductance falls below a threshold (5 mmol m-2 s-1). The scope camera is under $100.

A place to discuss the ecology and evolution of plants as well as the functioning of ecosystems. Companion to Resource Strategies of Wild Plants, Princeton University Press. Sunday, October 26, 2014. A long term record of alpine chamois weights from the Alps shows that body mass has been declining since 1979. The authors propose greater thermoregulatory demands as contributing to the declines, but the authors were unable to determine whether forage quality had declined. Saturday, October 25, 2014. If it ...

A few videos of bison calves walking over the scales and weighing themselves. Once we get EID's on all the mothers, we should be able to ID the calves, since they stay together. The top one weighed in at 50 kg and the bottom at 59 kg. Monday, June 23, 2014. New videos for pressure bomb.

Wild Plants Post: Reviewing literature on bison and nutrition

A place to discuss the ecology and evolution of plants as well as the functioning of ecosystems. Companion to Resource Strategies of Wild Plants, Princeton University Press. Tuesday, March 3, 2015. Reviewing literature on bison and nutrition. I'm going through the old literature on bison.not that there is much new literature. One thing I still haven't found is whether bison gain weight better with low-quality forage than cattle. Or do bison actually grow better on low-quality diets? It's a bit frustratin...

A place to discuss the ecology and evolution of plants as well as the functioning of ecosystems. Companion to Resource Strategies of Wild Plants, Princeton University Press. Tuesday, March 17, 2015. One more thought on Galileo's Middle Finger. One more thought on the book. The corollary from this research is that scientific knowledge does not matter. Dreger's book offers an alternative: evidence does matter. Her most concentrated thoughts on this are found in the epilogue. Dreger offers that counterpoint.

A place to discuss the ecology and evolution of plants as well as the functioning of ecosystems. Companion to Resource Strategies of Wild Plants, Princeton University Press. Monday, March 16, 2015. Book Review: Galileo's Middle Finger. There aren't too many books that would have blurbs on its cover from both Dan Savage and E. O. Wilson. This is probably the only one. And I've never read a book like it. All within 10 years by my count. These stories are not easy reads. These are stories of the role in...

Wednesday, August 27, 2014. Modeling competition for water: calling the race. Sensitivity of water uptake to changes in parameters for crops grown with weeds or weed-free. Parameters in the lower right are a lot more important when competing against weeds than when weed-free. Resources by weed-free crops.suggests that foraging fo...
