Brighter Planet
Year 3, Month 8, Day 26: Big Bee Gets The Honey
The Kitsap Sun (WA) is one of a number of papers running a Seattle Times story about a scientist who studies flowers:
SEATTLE (AP) — University of Washington researcher Elinore Theobald is studying the relationship between flowers and their pollinators on Washington’s highest mountain. And what she is finding so far — avalanche lilies at higher elevation set seed at one-third the rate of lilies elsewhere on the mountain — points to troubling questions.
Is it possible that the lilies are struggling because of a mismatch in their timing with their pollinators? And does that, in turn, point to trouble as the climate changes?
Theobald, a doctoral candidate, is working with field assistants Natasha Lozanoff and Margot Tsakonas to understand not just how a single species might be affected by even small changes in temperature, but how biological interactions between species respond to changing climates.
It is, if you will, a burning question: The average annual temperature in the Pacific Northwest has increased 1.5 degrees Fahrenheit since 1920, and is projected to increase an additional 3.6 to 7.2 degrees or more by the end of the century, according to the Climate Impacts Group at the University of Washington.
What might that mean for plant and animal communities? One way to find out is to head to the mountain, Theobald figured, where the range in elevation can be a proxy for the shifts in climate that are forecast.
She posits that understanding how plant and pollinator interactions are playing out at those different elevations today might be a clue to what will occur in the future. And if you love avalanche lilies, it might not be good.
A flower is a lovesome thing. Sent August 21:
One of the most important things to be learned from studying ecological relationships is that every living thing on the planet is connected intricately with countless other living things. Humanity’s perch at the high end of the food chain depends on the millions of complex symbiotic relationships that collectively form Earth’s biosphere — like those between flowers and their pollinators. The University of Washington’s Elinore Theobald and her team of researchers have uncovered some very troubling evidence suggesting that these examples of nature’s genius in fostering teamwork may be at considerable risk due to the rapid acceleration of global climate change.
Just as individual achievements depend on the infrastructure created by a well-functioning society, so is our species’ collective progress built on an environmental “infrastructure” millions of years in the making. While the past century of industrial growth has brought our civilization to a level of remarkable accomplishment, it has also disrupted the climate in ways that seem likely to have disastrous consequences.
If our internet goes out for an hour, we feel sorely inconvenienced. But the planetary environment is a larger, older, and far more essential kind of “world-wide web” — one we cannot afford to lose.
