In a recent discussion on Biofortified, a conversation regarding the ability of small scale research plots to represent real world results was raised. For reasons of experimental control, practicality, and economy, the majority of agricultural research is carried out at smaller scales, i.e. through growth chambers, greenhouses, and small field plots. Almost uniformly, the results of such studies are extrapolated to larger “field” level scales for reporting purposes. While this translation may seem like a straight forward conversion, it can have considerable affects on the interpretation and inference made from the research. Specifically, it is important to understand how error rates at the small scale carry over and affect the larger scale results.

There is so much information out there on Colony Collapse Disorder. Wouldn’t it be nice if someone summarized it in one place? Kyle Bailey, undergraduate in biology at Iowa State, has done just that. The following, posted with permission, is an up-to-date review of CCD research. It includes information from a variety of sources, from fact sheets to peer-reviewed journal articles.
Introduction
Honeybees (apis mellifera) are the primary pollinator available to agriculturalists in the United States. This makes them a critical part of US agriculture. Crops such as “almonds (82% of the world’s supply and 100% dependent on interstate pollinators); apples; cherries; blueberries; broccoli; carrots; cranberries; cucurbits like cucumber, melons, squash, pumpkins, and gourds” (Stankus 2008) are heavily reliant on honey bees for pollination. Traveling hives provided by commercial apiary services pollinates many of these crops.
A current epidemic, called Colony Collapse Disorder (CCD), affecting honeybee hives throughout the US threatens the apiarist industry. In the US during 2006-2007 29% of beekeepers reported some loss to CCD with some losing up to 75% of their stock (Winfree, Williams, Dushoff, et al). CCD is characterized as a mysterious loss of worker bees in the hive. There are no corpses to be found as the bees apparently wander far from the hive to die. The hive generally has sufficient food stores to maintain the population. The hives also generally still have undeveloped brood stock. The new brood (as well as the queen) is of course doomed without any adult workers present to care for them and they soon die. Because the bees travel far from the hive there are no bodies to necropsy and attempt to determine a cause (Stankus 2008).
This paper will explore the US economic and agricultural impacts of pollinator loss, and recent research into the causes of and potential solutions to CCD.

Alan McHughen, plant biotechnologist at UC Riverside and author of Pandora’s Picnic Basket, is one of the professors participating in Debating Science, helping the students to develop an informational website about bioethics that may one day be relesased to the public. He recently shared some insights with the group that he has allowed me to share with you (emphasis original)…

Planting for a Greener Yield
By Brandon Hunnicutt
Over the last 15 years, agriculture has been changing technologically at an amazing pace. It is something that is truly fun to look back at and realize where we have come. As a producer of corn, soybeans, wheat, seed corn, and popcorn over many of those years it has truly changed what we are able to do and what we will be able to do in the future.
Equipment technology has created a way for us to be able to be better stewards of our ground and resources. Biotechnology has allowed us to push the food, feed, and fuel production to levels that only a few short years ago, many people would not have thought possible. Plus, we are utilizing fertilizer at a better rate.
