Study finds that improved turf management techniques help golf course ecosystems succeed.
COLUMBIA, Mo. – Currently, there are more than 18,300 golf courses in the U.S. covering over 2.7 million acres. The ecological impacts of golf courses are not always straightforward with popular opinion suggesting that environmentally, golf courses have a negative impact on ecosystems. Now, researchers at the University of Missouri have determined that golf courses can offer a viable habitat for stream salamanders, and enhanced management practices may be beneficial to ecosystems within golf courses.

AUSTIN, Texas — Landscapes with large amounts of paved roads and impervious construction have lower numbers of ground-nesting bumblebees, which are important native pollinators, a study from The University of Texas at Austin and the University of California, Berkeley shows.
The study suggests that management strategies that reduce the local use of pavement and increase natural habitat within the landscape could improve nesting opportunities for wild bees and help protect food supplies around the word. (more…)
A Brown University class on the effect that climate change could have on human health has produced a free new curriculum for high school teachers. The nine-module unit, which reflects feedback from teachers, includes lecture background and ideas for warm-ups, in-class activities, and assessment.
PROVIDENCE, R.I. [Brown University] — Katherine Smith’s students had to wait until they came to Brown University to learn how climate change could affect human health. Now that Smith and her fall semester class have developed a rich new curriculum on the subject for high school teachers, future 10th to 12th graders might not have to wait so long.
The curriculum, a nine-module set of backgrounders, lecture notes and suggested lesson plans and classroom activities, is now available for free download. In 180 total pages, it covers topics ranging from an overview of climate change to more specific units such as how global warming could affect infectious disease, allergies, and the global food supply.

EAST LANSING, Mich. — Having natural habitat in farming areas that supports ladybugs could help increase their abundance in crops where they control pests and help farmers reduce their costs, says a Michigan State University study.
Ladybugs and other predatory insects eat crop pests, saving farmers an estimated $4.6 billion a year on insecticides. Non-crop plants provide these predatory insects with food and shelter, helping them to survive and thrive in areas where they are needed. In an attempt to increase benefits from predatory insects, researchers have often planted strips of flowers along the edges of crop fields. (more…)
*Growth of cropland, loss of natural habitat to blame*
The continued growth of cropland and loss of natural habitat have increasingly simplified agricultural landscapes in the Midwest.
In a study supported in part by the National Science Foundation’s (NSF) Kellogg Biological Station Long-Term Ecological Research (LTER) site in Michigan–one of 26 such NSF LTER sites around the world–scientists concluded that this simplification is associated with increased crop pest abundance and insecticide use.
