Observations at a Volleyball Court, accompanied by an ID & Behavioral Challenge

While on holiday in Oklahoma this weekend, I happened by this volleyball court on the way to the pool.   My attention was immediately drawn to movements that I observed in my periphery.  Here is what I observed from sand level…

and close-up from above…

The species may be territorial.  While individuals came close to each other it appeared like there were brief chases and overall there was an emergent spatial pattern (I think you can see it in the first video) suggestive of territoriality.   I tried to follow the movement of a single individual but it was too difficult for me.

After spending more time, continuing to ignore my children swimming and doing flips of the side of the pool, I made these more detailed observations suggestive of territoriality as well.  In the first video, you will see interactions between numerous live individuals with a single dead individual of the same species…

Here is a close-up image of an instance of this behavior…

In the second video, you will see interactions of these hymenoptera with a mottled leaf…

Here is a close-up image of an instance of this behavior…

The fact that the colors of the leaf are similar to some of those found in the wasps themselves made me wonder if I could elicit the behavior with another leaf.  The leaf I chose to use, unlike the one I found them naturally interacting with, was entirely yellow.  What do you hypothesize will happen?

Around the periphery of the volleyball court, I noticed holes in the sand that were approximately the same diameter as the cylinder shape of the insect themselves (see below), although maybe a bit weathered.  I should have dug them up but didn’t think of it at the time.

I had noticed similar behavior in a much smaller number of cicada killers in a children’s sandbox, but had no idea what type of hymenoptera this species was.  Similar, I wondered, was this a mating swarm?  Where they recently emerged individuals?  What was the ratio of genders?  How long does this behavior persist?  What resources might they use to maintain their energy?

A few curious individuals did happen to come by while I was making my observations, and I received seemingly conflicting reports on their longevity.  One adult mentioned that they are there all the time, while a couple of kids arriving to play volleyball hadn’t noticed them there the day before.  In fact, later that night I saw, from afar, four people playing volleyball.  I might add, that to get some of the images and video, I walked in amongst the swarm.  I did so slowly but felt that they may have ignored me even if I had walked in at a normal pace.

So, here’s the challenge…

• What is the genus and/or species of this hymenoptera?  and
• What the heck are they doing?

As mentioned in response to Brad’s post on aphids, I think a collection of such videos and images could make an interesting series of ecological activities for students, and possibly a series of models for them to produce their own reports, blogs, etc… on interesting outdoor observations that can motivate learning of particular ecological principles.

For anyone that responds with the answers, unknown to me with any certainty, it would be nice, and potentially helpful in the future, for you to provide links to websites that helped in your identification.

Observations of tadpoles in a local pond

Two days ago, while driving my eldest daughter and a friend to morning swim practice, we ran across, but not over, a rather large snapping turtle crossing the road.  This happened just east of Mission Road on 71st Street in Shawnee Misson, Kansas (it appears that he may have grown up in Indian Hills County Club).  Although the turtle appears to have lived quite a productive live to that moment, we figured that we might increase its life span by moving him somewhere a little bit less populated.

Yesterday, my two younger children and I, released our find in a wetland area adjacent to the Blue River in southern Johnson County.  While there, I treated my kids to one of the ponds I frequent with students when I am teaching about amphibians.  Here is an interesting observation that we made…

A quick google search this morning suggests that field biologist may not fully understand this behavior, and not for lack of thoughtful consideration and experimentation.  I know that school is out and that critical observations and experimentation are dependent on the life cycle of an organism who doesn’t realize that, but I share this observation none-the-less, for its potential…

…and if you want to ID the tadpoles you can do that too…

Reflections on the KABT Field Trip in Logan County, June 4-6, 2010

I am not sure what KABT’s goal for the field trip were but for me they were two-fold.  I wanted to provide an inspirational outdoor experience for four of my senior students, and two of my children, who eagerly participated in the trip, while learning myself about the wonderful short-grass prairie from our very own sage, the Yoda-like natural history master, Stan Roth. 

In both regards the trip was a resounding success, even though I failed to continue to follow Noah’s driving lead into better pastures where he was finally able to witness the character of our pursuit, the endangered a recently re-established Black-Footed Ferret (see Noah’s posts). 

If you are sad that you missed the trip, continue on since I did my best to record it all for you…

More specifically, follow along to see what I saw, learn what I learned, listen while I contemplate what KABT may have learned, and educate yourself on the prairie dog wars of Logan County, Kansas in hopes of a return trip to this wonderful county…

Looking for a new outdoor ecology investigation to conduct with your students?  … something that will require them to get their hands dirty?  … and aid in their learning and appreaciation for our native fauna? 

Then look no further than the new citizens science project, Earthworms Across Kansas organized by Dr. Bruce Snyder at Kansas State University.  As stated on their website and in an introductory letter I recieved a few weeks ago…

Earthworms Across Kansas is a free program that engages middle and high school students throughout the state in answering some basic, yet unanswered questions about Kansas earthworms, such as “Which species are here?” and “What are the ranges of these species?”

The project aims to educate Kansas’ middle and high school students about earthworm biology and invasive species issues by engaging them as citizen scientists.  One-third of the approximately 170 species of earthworms known to reside in the United States have arrived here from another continent.  We expect that most every earthworm your students collect will be an exotic species.

We are currently recruiting teachers to participate (online registration form), although only until we run out of kits.  Once registered, you can prepare for your participation by viewing curricula and lesson plans associated with earthworm biology that will be posted online through May.  In July or August your kit will be mailed, and your students can complete their collecting anytime during the 2010-2011 academic year.  The data from across the state will be uploaded on their interactive google map, and thus facilitate your students answering the basic questions posed by the project.

If you’d like more information about the program before registering certainly visit their website, and if you have further questions, please email the project at earthworm@k-state.edu.

I haven’t read through the protocols for this project yet but thought you may interested in learning from the active worm collectors and the research associated with their methods.  Check out Worm Grunting, Fiddling, and Charming—Humans Unknowingly Mimic a Predator to Harvest Bait published in PLOS.  Besides the article there are a number of interesting quicktime video links demonstrating the research.

George Pisani and Bill Busby are looking for help.  You, your students and other interested parties can help expand the knowledge of two Eastern Kansas snakes:  Red-bellied and Smooth Earth Snakes.  Note that these are some of the earliest snakes to show up in the spring (March).  Spread the word to others in your community.  If you want to participate you’ll need to get going. Here are the details:

Smooth Earth Snake and Redbelly Snake Population Survey

Kansas Biological Survey (KBS) is conducting a survey of these two Kansas snakes recognized as Threatened in the State. We are looking for new populations and ask that students and teachers in the eastern counties of Kansas be on the lookout for these species in your area, and report sightings to us using the report form available at http://people.ku.edu/~gpisani/SWGform.html. Sightings must be confirmed by us, either by a live specimen (which may be released at capture point after we confirm identification) and/or high-quality photograph. We also need detailed documentation of habitat in which you may find them! If you find either species, note the area well and contact us ASAP! We especially need people to help us in Linn and Anderson counties; email us as soon as possible if you can help.

Both species are cool-weather snakes, and are among the very earliest to emerge from hibernation. Look for them under cover objects (tin, rocks, wood) from early March on (depending upon temperature). A great way to locate these snakes is to distribute 2ftx4ft pieces of salvaged barn tin (the corrugated kind) in likely habitat, especially edge zones between woods and unmowed grass areas. Part of this effort is to determine just what sorts of habitat both species prefer, so don’t overlook pastures, woods , or whatever habitat is in your area.. Spread some tin [with landowner permission]; see what comes in! And don’t forget to remove the tin when done sampling an area..
For an overview of current Kansas records of these species, visit the Kansas Herpetofaunal Atlas pages from links on our web site (above).

To add incentive, we will award publications to people with the most confirmed sightings in new localities during 2010 as follows:

Most new localities reported: A copy of 2nd printing (1980) Autecology of the Copperhead 1960 by Henry S. Fitch and also a copy of 2nd printing (1991) Reproductive Cycles in Lizards and Snakes 1970 by Henry S. Fitch.
Second place, most new localities reported: CHOICE OF ONE OF THE FOLLOWING- a copy of 2nd printing (1980) Autecology of the Copperhead 1960 by Henry S. Fitch and also a copy of 2nd printing (1991) Reproductive Cycles in Lizards and Snakes 1970 by Henry S. Fitch.
Third place, most new localities reported:  A copy of Biology, status and management of the Timber Rattlesnake (Crotalus horridus): A guide for conservation (1993), by William S. Brown.

A post just came through the KS-Bird list about an interesting Cornell Citizen science program:

The Rusty Blackbird Blitz

Rusty Blackbirds are in decline and Kansas is part of their winter range.  This “blitz”/survey is set up for the first two weeks of Feb.  Check out the link for protocols.  If you decide to get out and count blackbirds don’t just report to eBird;  share your experience here on the KABT BioBlog.

An excerpt from the Cornell eBird website:

January 11, 2010

Populations of Rusty Blackbirds are crashing! Their numbers have plummeted by as much as 88-98% over the last few decades, according to data gathered between 1966 and 2006 for the North American Breeding Bird Survey and Christmas Bird Count. A species that was once considered to be abundant is rapidly disappearing before our eyes. Your observations can help save this species by arming scientists with critical information about its ecology. The Rusty Blackbird Working Group has developed the Rusty Blackbird Blitz, a winter survey whose goal is to count Rusty Blackbirds range-wide just prior to spring migration.  From 30 January – 15 February, search for Rusty Blackbirds in your area and report your observations to eBird.

Before the weekend, I received an e-mail from a colleague asking “Do you know of a good place I can go gather termites… anywhere woody?”

I responded with my suggestions, and because I was intrigued, I replied with a question of my own, “What do you plan to do with them?”

Well, after a making my own way through portions of two decaying logs, and acquiring some special and not-s0-special writing utensils, see what we ended up witnessing by watching the following videos… 

1. Termite and paper (30 sec.)
2. Termite, paper, and pencil drawn Infinity (30 sec.)
3. Termite, paper, and Sanford Uniball Black drawn Infinity (30 sec.)
4. Termite, paper, and Papermate Red drawn Infinity (30 sec.)
5. Termite, paper, and Papermate Red drawn Spiral (30 sec.)

Sorry for the out-of-focus imagery but I hope these 2.5 minutes of observation motivate you as much as they did us before we introduced these creature to our classes today!  Experiment with other colors, other writing utensils, and have fun googling to see what is already known about the behavior you witnessed.

Happy Inquiry!

Those of you who have followed this blog probably know of my long time fascination with antlions.  If you have a ready source of them, they make a great organism to inspire student generated research.  Today, I’ve run across two excellent photo resources on antlions.  Alex Wild’s Mymercos Blog has exceptional images of an antlion in action and in the comments to Alex’s amazing photos you can find a link to Mikko Kolkkala’s images of an antlion parasatoid.  Check them out you’ll be amazed–maybe you’ll even go to the trouble of collecting antlions this summer for the first week of school next year.

No Child Left Inside: How Can We Help Connect Children with Nature?
Tuesday, June 2, 2009
7 p.m. – 8:30 p.m.
Central Resource Library

Is there such a thing as “nature-deficit disorder?” Do children have a biological need to be exposed to the natural world? Whose responsibility is it to make sure that kids get a chance to encounter nature and how can we make sure that these opportunities are available to all? Join our panel of experts from the fields of science, education and community development to explore this important topic.

This year’s Spring field trip will be on Saturday, June 6, at Cheyenne Bottoms Wildlife Area.

From Fort Hays Univeristy Wetlands Education Center Website

We will be meeting at 10am at the Kansas Wetlands Education Center at the Bottoms.  We have reserved a classroom there, and are asking participants to bring any materials we can use to collaborate and create a lesson/lab or two that we can then take back and do with our classrooms next year.  That may mean bringing laptops, microscopes, slides, petri dishes, dropping pipettes, cameras, nets, buckets, binoculars, etc.  The classroom that is reserved has tables and chairs, and that is about it, so we need to bring all of our own lab equipment.

For those who want to arrive Friday and camp out, we will be at the Venango campground at Kanopolis State Park, about 45 minutes northeast of Cheyenne Bottoms.  Friday evening we will have fly fishing, bird watching, and other activities for those who are interested.  Please bring your own camping gear and food.   (Please see the Venango link for camping costs).

Friends and family are welcome!  Hope to see you there!
