Neonictinoids: dangerous to bees and more, with negative consequences for entire ecosystems

Researchers continue to amass evidence showing the harmful effects of neonictinoids in pesticides.  National Geographic's news report for a general audience gives an overview, and many scientific papers are quickly found with a search on neonictinoids in Web of Science.  Here are a few of the most recent, beginning with two articles in the open access journal PLOS One.

Tan, K., Chen, W., Dong, S., Liu, X., Wang, Y., & Nieh, J. C. (2014). Imidacloprid alters foraging and decreases bee avoidance of predators. PLOS One, 9(7), e102725. doi:10.1371/journal.pone.0102725
Partial abstract: “Concern is growing over the effects of neonicotinoid pesticides, which can impair honey bee cognition. We provide the first demonstration that sublethal concentrations of imidacloprid can harm honey bee decision-making about danger by significantly increasing the probability of a bee visiting a dangerous food source.”

Getting ready for the new year!

Summer is fleeting away, and some of us are trying to squeeze just a little vacation into what is left of August.

Meanwhile, orientation for new faculty has begun and the class of 2018 will be moving in next week.  It's an exciting time of year.  Many of our colleagues around the state have already welcomed incoming and returning students and are in full academic year mode.  By mid-September, these waning days of summer will be a fading memory.  For now, enjoy the relative peace in the science library, where the new book shelves are still brimming with fascinating tomes and a new printer sits gleaming in the copy room, promising reliable performance (hurray!).

Eco Tour app available for download - share it!

Bridget Flynn, OC's Sustainability Coordinator, made the following announcement today:
Oberlin College's Eco Tour app [for iPhone, iPad or iPod] is now live and available for download on the Apple App Store. This app highlights various sustainability-related places of interest on campus.

The campus sustainability map can also be viewed in a Google map online and will be up on the OES website by the end of this week.

OES student intern Parker Oka-Wong developed the app, with guidance and support from CIT, Communications Office, and others over the past year.

Congratulations to the OES team.  Even if you know Oberlin very well, you'll learn something new and interesting and enjoy the images on the app - give it a try!
