Slime, spores…fungi!

One of many sessions that will focus on species interactions at ESA’s 2013 Annual Meeting by Nadine Lymn, ESA director of public affairs As different from plants as plants are from animals, Fungi feature varieties that decompose dead organisms, engage in mutually beneficial relationships with other species, cause disease to plants and animals, and act as predators and parasites.  Mycologists—those who study…

One of many sessions that will focus on species interactions at ESA’s 2013 Annual Meeting by Nadine Lymn, ESA director of public affairs Human cases of Lyme disease continue to rise in the United States. The bacterial disease—which, if untreated can cause significant neurological problems, is transmitted to people by black-legged ticks, which pick up the pathogen by feeding on…

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.

The 2001-2002 drought in the Southern Rocky Mountains turned a bark beetle outbreak into an epidemic, withering the lodgepole pines, according to a University of Colorado study published in the October 2012 issue of Ecology

Water for the trees

Saving forests from drought as the climate warms.

Drought complicates the big problems afflicting modern forests. Gordon Grant, Christina Tague, and Craig Allen think that mitigating drought stress should be an active priority for management of US public forests – in keeping with the US Forest Service mission to “improve and protect the forest” and “secure favorable conditions of water flows”.

Zeal to ensure clean leafy greens takes bite out of riverside habitat in California

Perceived food safety risk from wildlife drives expensive and unnecessary habitat destruction around farm fields By Liza Lester, ESA communications officer Meticulous attention to food safety is a good thing. As consumers, we like to hear that produce growers and distributers go above and beyond food safety mandates to ensure that healthy fresh fruits and vegetables do not carry bacteria…

Looking to large tributaries for conservation gains

By Liza Lester, ESA communications officer Mississippi River Basin. Green tributaries have sufficient flow for large-river specialist fishes, and long stretches unobstructed by obstacles of civilization. Blue tributaries fall below a critical flow threshold. Yellow tributaries discharge enough water, but are blocked by dams. On big rivers like the Mississippi, the infrastructure of modern civilization – dams, locks, dikes, power…

Vegetables under plastic

Weighing the costs and benefits of plastic vegetable greenhouses over conventional vegetable production. By Liza Lester, ESA communications officer The USDA Natural Resources Conservation Service offers “seasonal high tunnel” kits as part of a three year trial to assess the potential of the plastic houses for conserving water and soil, reducing pesticide use, and improving yields for small farmers.

Depression-era drainage ditches emerge as sleeping threat to Cape Cod salt marshes

Contemporary recreational fishing combines with old WPA project to hasten marsh die-off By Liza Lester, ESA communications officer   CAPE Cod, Massachusetts has a problem. The iconic salt marshes of the famous summer retreat are melting away at the edges, dying back from the most popular recreational areas. The erosion is a consequence of an unexpected synergy between recreational over-fishing…

Baltimore’s Watershed 263 experiment in socioecology

Ecological restoration makes city dwellers happier and healthier. by Liza Lester, ESA communications officer IN the first summer after my move from the cool green climes of western Washington State to Washington, DC, I gained a primal, physical understanding the urban heat island effect. Summer in the District of Columbia is a hot, humid shock for a native northwesterner, and…
