Fire-scarred trees record 700 years of natural and cultural fire history in a northern forest

A new paper in Ecological Monographs presents a 700-year dendrochronological record of fire in Trillemarka-Rollagsfjell nature preserve in southern Norway. Burn scars on old tree stumps chronicle social change, from the population crash at the time of the bubonic plague, through a spike in slash-and-burn agriculture, to the rise of the timber economy.     Until the modern era, the human mark…

The Rim Fire one year later: a natural experiment in fire ecology and management

The enormous conflagration known as the Rim Fire was in full fury, raging swiftly from crown to crown among mature trees, when it entered the backcountry of Yosemite National Park in California’s Sierra Nevada in late August 2013. But inside the park, the battle began to turn, enacting a case study in the way management decisions and drought can combine to fuel large, severe fires.

The control of nature: stewardship of fire ecology by native Californian cultures

Before the colonial era, 100,000s of people lived on the land now called California, and many of their cultures manipulated fire to control the availability of plants they used for food, fuel, tools, and ritual. Contemporary tribes continue to use fire to maintain desired habitat and natural resources.

Celebrating Earth Day in 2014

Me and milkweed fruit – my #NatureSelfie for #EarthDay. Nash Turley, a naturalist, photographer, musician, and PhD student in evolutionary ecology at the University of Toronto, snapped this shot in Ithaca, NY, in 2011. He tweeted, “Everyday is Earth Day; the fact that the calendar says today is ‘Earth Day’ doesn’t really mean anything to me. Sort of like how aboriginal cultures don’t have a word for ‘nature’ because they didn’t see themselves as separate from nature….the fact that we have a day for the Earth shows how disconnected modern societies are from ‘nature’.”
Earth Day started as a grassroots protest movement in 1970 and has solidified into an annual event. What does Earth Day mean in 2014?

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.

Ecology branches into the tree of life

An August 2012 supplementary issue of Ecology explores the interface of ecology and phylogenetics.

Watercolor and pencil. Österreichisches Museum für angewandte Kunst, Vienna. NATURALISTS of the late 19th century tended to holistic interpretations…

The genealogy of watersheds

When I was a kid, July and August always included at least one fishing trip with my grandmother. She was not a great angler, but she was brave. I will never forget watching her tramp through tall weeds in search of grasshoppers. Upon finding one, she would quickly snatch it up with her bare hands and then smilingly pierce it with a small hook on the end of her ancient fishing pole. It did not take long for a hook thus baited to attract a bite.

From the Community: Ecology in uncommon roles

Based on news articles and studies from last week, ecology can be involved in serenading your mother, inspiring fashion, describing the fundamentals of politics and guiding robots in nano-scale terrain. Here are a few examples of ecology in uncommon roles from the second week in May.
