Evening Primrose by any Other Name is a Moth Plant

Plants provide us with many things that we use on a daily basis – from the buildings in which we live and work, to our clothing and food. For flowering plants to thrive and reproduce, they often rely on pollinators to transport pollen between flowers.

Pollination ultimately results in fruits and seeds, ranging from the strawberries and almonds in your breakfast to the tomatoes in your pasta sauce. While scientists know a lot about honeybees, very little is known about many other pollinators – bats, birds, bees, butterflies, moths, flies, etc. – that are essential to pollinating wildflowers and native plants.

Young Scientists Network, Share Urban Research in New York City

For young scientists, the years between completing a dissertation and becoming established in your field of research is sometimes an isolating time. The scholarly support of coursework is behind you just at the moment when you have refined your area of expertise.   As a research social scientist with the U.S. Forest Service’s New York City Urban Field Station, I wanted to help bridge that gap by fostering a network of young scholars and engaging them in New York City as a living laboratory for urban research.

For three days, the Urban Field Station, located at Fort Totten in Queens, New York City, served as a home base for scientists participating in a workshop titled, “Urban Natures: Engaging Social Science Perspectives.” The workshop was a rare opportunity for Ph.D. candidates and early-career faculty members in disciplines including geography, environmental psychology, natural resource management, and environmental studies, to explore the connections between research and practice in social-ecological systems in a peer-to-peer setting.

Moths Aflutter in Honor of National Moth Week

The luna month (Actiasl luna) have pale green wings with long curving tails and a wing span of roughly 3 to 4 inches. They are strong fliers with an attraction to light and can been seen, depending on the area of the country, between May and September. (National Park Service)

Imagine wandering through your favorite botanic garden in the early evening and catching a glimpse of the moon reflected off of something lime green that moves from flower to flower while closer to the ground the yellow glow of fireflies help illuminate the night.

It’s enough to make you feel like you’re in a Shakespearean forest.

But the lime green is really the wings that belong to what some consider the most beautiful insect – the Luna moth. Those who do catch a glimpse of this unique moth are lucky – as they are rarely seen due to their short life span. Read more »

Leaf Litter Keeps Ground-Roosting Bats Warm

When winter weather arrives, most bats hibernate in caves, but a few species migrate to warmer areas. Warmer being relative, the migrating bats may still end up in places that are too cold for comfort, and sometimes hibernate under leaf litter for short periods of time.

Roger Perry, a wildlife biologist at the U.S. Forest Service’s Southern Research Station, studied these temporary hibernation sites to find out how much protection they offered bats, and how much energy bats expend to stay alive.

The leaf litter study took place in and around the Alum Creek Experimental Forest of the Ouachita National Forest in Arkansas, and focuses on eastern red bats, a migratory species that remains active through most of the winter. When winter temperatures are not too cold the bats roost in trees, but when temperatures plunge, the bats temporarily hibernate underneath leaf litter. Read more »

A Lifetime of Statistics

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

As long as I can remember, I’ve had a passion for numbers and statistics. That’s why I’ve dedicated the last 39 years of my life to this amazing field.

I earned my degree in statistics in 1975 and shortly after that joined the U.S. Census Bureau, where I worked for 21 years.  At the Census Bureau, I had a really diverse experience, having worked on crime, housing, economics, and labor statistics, before ending up with the Census of Agriculture team. It was when this team transitioned to the National Agricultural Statistics Service (NASS) in 1997 that I joined my new home away from home at USDA. Read more »

Getting Geeky at the 3rd Annual USA Science and Engineering Festival

When you think of agriculture do you think of science and engineering? You should! Farmers are some of our original scientists, tinkering with plant varieties and farming techniques to find ways to reliably grow food. At USDA, we still do that kind of research in a never-ending effort to find better ways to produce food, fuel, and fiber. We also do a lot of research you might not think of when you think about agriculture: from forensic genetic analysis to track down unwanted pests to figuring out how to turn spent grain from distilleries into biodegradable kitty litter.

On April 26-27, the 3rd Annual USA Science and Engineering Festival took over the Walter E. Washington Convention Center in Washington, D.C. Over 325,000 people came out to celebrate discovery and innovation through over 3,000 hands-on activities and 150 performances and lectures.  USDA pulled all of the stops to show our geeky side and hopefully convince a few young booth visitors to consider agriculture when they think about careers in science.
