by Suzie Henderson, Athens Science Café What is an ecosystem engineer? Every ecosystem, even arctic ice [2], is subject to the influence of ecosystem engineers [3]. An ecosystem engineer alters habitat and consequently changes resource availability to other organisms [2]. Even though all organisms play a role in resource cycling to varying degrees, not all
Written and Illustrated by Uma Nagendra Uma Nagendra is a PhD Candidate at the University of Georgia and became interested in studying natural disasters since Hurricane Katrina hit her hometown of New Orleans. She enjoys finding creative ways to demonstrate complicated ecological concepts—preferably if it involves running around outside or drawing pictures. When not crawling over downed
If you read the first installment of our ScienceCafé invasive species series, you may have already guessed the name of this topic: Pueraria lobata, or… kudzu! Before kudzu arrived in the states and poison ivy was the only three-leaved vine, times were simpler. No one worried about kudzu invading their yard and killing their plants
If you drive longer than five miles in the South, you'll undoubtedly see an abandoned lot covered in kudzu. Up until the 1950s, farmers transplanted the fast-growing vine from Asia to the U.S. to stop soil erosion along roads. Individual kudzu vines can grow more than 100 feet per growing season, easily spreading over the
I will attempt to graze over a topic ubiquitous in the southeast: invasive plants. With over 5,000 nonnative plant species in the U.S., you could say that this is no small problem, whether it is in our hands or not. You may ask yourself: Why should I care about the spread of some obnoxious, ugly
Around mid-summer each year, stories about wildfires, especially in the Western United States begin to dominate the news. Since 2000, there have been between 40,000 to 100,000 wildfires in the U.S. each year that are responsible for an average of 19 fatalities and 7 million burned acres (about the size of Massachusetts). When humans live
