Phenology

A male broad-tailed hummingbird sips nectar. The phenology of the early-season nectar plants the bird favor is changing more rapidly than the birds, leading to the potential for a mismatch that could affect both birds and their nectar resources. Credit, David Inouye.

GLOBAL CHANGE IS NOW. Ecology can help.

Same Data, Different Century. Sometimes I believe I was born to be a 19th century naturalist. Compiling long term records of flowering phenology involves stitching together old data (for example, this herbarium specimen from 1895) with new data (a phenology observation collected on a smartphone app in 2013). As I trek across Mount Desert Island in the 21st century, I am keenly aware of the naturalists who came before me; in my mind, I insert myself into the troupe of Harvard boys whose field notes and camp logs have become my baseline data. I really love S. A. Eliot's sweater. Caption, Caitlin McDonough MacKenzie.

In phenology, timing is everything

If you’ve ever thought that botany doesn’t involve enough time travel, you are not alone. Plant ecologists studying climate change and and the timing of flowering are constantly wondering ‘is this happening when it used to happen?’ My job would be infinitely easier if I had access to a time machine.

A unified field theory for public participation in scientific research

Disparate citizen science disciplines come together at the Public Participation in Scientific Research conference by Liza Lester, ESA communications officer The idea of a big, cross-disciplinary meeting had been floating around citizen science circles for a while. Though public participation in scientific research has deep roots in the history of science, in the last few years it has taken off…

Phenology, bees and climate change video

The Goddard Space Flight Center at NASA just put out this excellent video about pollination, phenology and the effects of climate change. Although NASA has satellite data showing that spring green-up has been occurring a half-day earlier each year, it’s a bit harder to figure out whether a corresponding change in phenology is occurring among pollinators. The video shows beekeepers–scientists…
