The ALE lab has a brand new website! <a href="http://ale.cfaes.ohio-state.edu/">gardinerlab.cfaes.ohio-state.edu</a><br />
<br />
Since this website has a handy "News" feature we probably will not be posting any more blog posts here.<br />
<br />
Also, don't forget to check out our <a href="https://www.facebook.com/pages/The-Agricultural-Landscape-Ecology-Lab/266781896717694">Facebook</a> which is where we post ALE Lab news as well!<br />

Chelsea and Mary recently published a paper in the open access journal: PLOS ONE. This paper investigated the intraguild predation (IGP) hypothesis for native lady beetle decline. Previous studies have suggested that native lady beetles are declining due to predation on their eggs and larvae by exotic lady beetles. Through egg predation experiments we found that significantly more native lady beetle eggs were consumed by predators than exotic lady beetle eggs. However, using video surveillance, we discovered exotic lady beetles to be an uncommon predator, providing evidence against the IGP hypothesis for native lady beetle decline. Additionally, the guild of predators observed feeding on native and exotic lady beetle egg masses was diverse and interesting, which could lead to many more questions!</div>

They are generalist predators which means: they eat many different things, especially agricultural and house hold pests! Since they hunt a variety of pests we consider them to be important biological control agents, meaning they eat pests for us so we don't have have to use as many insecticides.<br />
<br />
Spiders may be among the most misunderstood of arthropods. Most people have heard about the brown recluse to be dangerous, however much of that information is misleading. For starters...the range of the brown recluse just barely reaches the South-western tip of Ohio, so Ohioans should not fear!<br />

We found two wild honey bee hives. Sorry...didn't take any pictures, we just avoided them. We were not very interested in finding out if the bees were aggressive or not, although it is probably safe to say they were not aggressive since it took us awhile to notice them.</div>

I probably should have checked the weather before making that decision...several inches of snow later.....I collected what was left of the caterpillars this afternoon. Two sets (six caterpillars total) were on plants that died and though I tried, I could not find the caterpillars! Of the two other sets I did find, there were two caterpillars that had interesting marks. First I referenced what some common predation marks might look like:<br />

What do you guys think? Both of these caterpillars had been secured to branches of a pine tree. I'm guessing this experiment would be a lot more interesting if it was done in the spring!<br />

There is a bit more to the program than just the experiment but the fun part for us is that we get to test out the experiment before preparing the teaching materials that will be used for the outreach program. If you can't find the caterpillars, you can click the photo for a larger image.</span></span><br />

<br />
We had left some vegetation in the field after harvesting back in August-September. We figured since we have first year plants this would be beneficial as the plants need their leaves to photosynthesize (create energy) to build up their roots systems.<br />
<br />
Before we cut the plants down the field looked like this:<br />

Many growers will cover their hop plants with mulch or compost after cutting them back. This is supposed to help protect the crowns from freezes. We decided to go mulch free to find out how that method would work for Ohio hop growers.<br />

Hey everyone! I figured since I have survived my first week in the ALE lab, it was time to introduce myself. My name is Nicole and in the attached picture is Cody. So what's my story? I was in the Navy for a bit, which is how I ended up with Cody. I was stationed in Italy first, then Spain and in Spain we had a kennel on base. It was love at first sight. Cody was about four or five months old when I got him and he's been with me ever since. I moved to North Carolina when I got out of the Navy and there I attended Queens University of Charlotte where I received my BS in biology. I am all set to graduate from Winthrop University, which is in Rock Hill, SC, in December with my MS in biology. If I had to throw a label on myself, it would be molecular ecologist. I really enjoy having a molecular component to my studies. My thesis research involved sampling amphibian populations at a local state park and testing them for the presence of <i>Batrachochytrium dendrobatidis</i> (Bd). Bd is a chtyrid fungus that infects the skin of amphibians and can cause the disease chytridiomycosis, which can be fatal in some species. I enjoyed my research and was very grateful to have picked up the skill sets I did, especially all the molecular work, while doing it as this was key to my being chosen as the new research assistant for the ALE lab.<br />
<br />
So what will I be doing here anyways? I was hired on to help with what we're calling the vacant lot study, which is the project Mary recently received an amazing grant for. I am very excited to be a part of this research and am looking forward to getting started on the project. The molecular aspect of the study will involve determining what some of the predators are eating. I hope to start testing protocols for that this winter so that we'll be ready when it's time to start collecting the selected specie and begin testing them. Working with arthropods is new for me and this roughly translates to reading, reading and more reading. Thankfully I actually enjoy learning about anything ecology related.<br />
<br />
Even though my first official work day was Monday, I attended the Stinner Summit last Friday with Mary, Chelsea, Andrea and Carol. It was a great introduction to the area and I loved the concept of the summit. The attendees work together to come up with projects that involve healthy agroecosystems and sustainable communities. There are numerous sessions in which attendees break off into groups to develop and explore an idea for a project by coming up with a mini-proposal that is then pitched to the other attendees and, at the end of the day, the attendees donate "Stinner bucks" as well as IOU's (can be for labor, expertise, money, etc.) to the projects they would like to support. The bucks are turned into funding through the Ben Stinner endowment. It was such a cool experience to see so many different groups of people come together and I think at the end of the day there were about six projects that received funding. My time this week has involved learning where to find things in the lab, learning pinning from Chelsea and Cali and yesterday I took my first trip into Cleveland to help Chelsea get soil samples for another project the lab is collaborating on. It's been a fun week and I am truly thankful that the opportunity to be a part of a lab with such a great group of people presented itself to me. I have had nothing but good feelings and excitement since I received the email from Mary saying that I had gotten the job and I know this will continue throughout my time here.

After our first week of pest sampling we have seen no sign of two-spotted spider mite (<i>Tetranychus urticae</i>) or hop aphid (<i>Phorodon humuli</i>). Michigan hop researchers and growers have reported signs of downy mildew in their fields (<a href="http://msue.anr.msu.edu/news/michigan_hop_update_june_12_2013?utm_source=Fruit+Production+-+MSU+Extension+News+-+6-13-13&utm_campaign=Fruit+6-13-13&utm_medium=email" target="_blank">MSU hop update</a>) and we are keeping our eyes open for signs of the disease as well.</div>

My last post was way back in the fall when I joined the ALE lab as a new Masters student. Things have been going great and I now have a project in the works. I am interested in how landscape composition and management practices affect the natural enemies found in vegetable crops, specifically sweet corn and summer squash. I am also sampling for long-legged flies (a type of predatory fly that is rather ubiquitous) to see if they can be a bioindicator group of the natural enemies in agroecosystems.<br />

And now that summer is here, field work is officially under way! I spent last week deploying traps at 16 field sites throughout northeastern Ohio. The three types of traps I am using are pitfall traps (a cup of water in the ground with soapy water to keep the critters from crawling back out):<br />

Ben has tested floral strips which he planted next to his pumpkin plots, and one of the flowers he tested was sweet alyssum. While Ben has been busy writing his thesis...a study came out of Washington State University that tested the effect of sweet alyssum placed next to orchards. They found a significant decrease in the number of aphids in plots with the flowers compared to plots without flowers. For more info check out the article: <a href="http://www.sciencedaily.com/releases/2013/05/130514101446.htm" target="_blank">www.sciencedaily.com: Controlling aphids with flowers</a><br />
<br />
Ben will be presenting his results soon, and we are excited to see if he had similar results!<br />

The mechanisms as to why this is the case have been unclear. Is <i>Harmonia </i>a more effective predator than natives? Is it merely eating the natives at a particular life stage (termed intraguild predation, and the topic of Chelsea's M.S. thesis)? Does it have a faster life cycle and therefore able to reproduce in higher numbers?<br />
<br />
A new study published today in Science reports that <i>H. axyridis </i>may be such an effective invasive species due to microsporidia in its hemolymph. These microsporidia are safe for their hosts, but when native species (to Europe), such as <i>Coccinella septempunctata</i>, were injected with these microsporidia they died. In the field, this may mean that consumption of <i>H. axyridis </i>eggs is lethal to intraguild competitors.<br />
<br />
<i>C. septempunctata </i>is also established in the U.S., and is a dominant competitor of our own native species. It will be interesting to see how these new findings will influence our understanding of American native lady beetle declines.<br />
