Nature 2002. 416: 389:395 Increasing climate includes phenology of organisms. Phenology is the seasonal timing of species developing life history over the growing season. Examples include flower development, bird migrations.
Many plants in the Miami Valley are flowering earlier Many plants in the Miami Valley are flowering earlier. Some species are substantially earlier. There appears to be a relationship between phenology change and time of the year there is an apparent straight-line relationship early in the diagram. But Phlox and Hosta throw off the relationship
We divide these species into responders and stable species We divide these species into responders and stable species. The source of this variation is unknown. Some species respond to temperature- others to photoperiod (how long the sun is in the sky). This may be the source of variation: Why?
Why are these species flowering earlier Why are these species flowering earlier? We found that flowering change is most closely linked to winter temperaturess. There was also a relationship with temperature in June. Why?
If you combine temps Jan through Feb If you combine temps Jan through Feb. The relationships with the most rapidly changing specie is strong. What does this mean?
One of the impending issues in ecological systems with climate change is the idea of climate-response mismatching. This comes about when one species responds to increasing global temperature while other species upon which t he species relies, do not. Why does this matter? What are some examples?
What does this mean for restoration http://www.nrs.fs.fed.us/atlas/
