Finding the flora and fauna: Butterfly Center staff conduct a BioBlitz in Memorial Park

Editor’s Note: The term “BioBlitz” was first coined in 1996 for intense attempts to record all the flora and fauna within a designated area. National Geographic, which has partnered with parks around the country for various BioBlitzes, describes them as “a 24-hour event in which teams of volunteer scientists, families, students, teachers, and other community members work together to find and identify as many species of plants, animals, microbes, fungi, and other organisms as possible within a designated area.”  These quick and dirty surveys are used both to gather information about the biodiversity of a given area, and since members of the public and other non-experts (students, etc.) are often included as participants, as ways of sparking public interest in local flora and fauna.

The “Eco-Tech” panel of the Memorial Park Conservancy recently recruited the Butterfly Center to conduct a preliminary survey or “mini-BioBlitz” of the insect fauna throughout Memorial Park, with the idea of inviting members of the public to help on future surveys. One of the goals of the panel is to get some baseline data on the biodiversity of all the creatures that live in Memorial Park, and from there, make plans on how best to preserve and manage or enhance this wildlife.

We were asked to survey several different natural habitats in Memorial Park (i.e., not the golf course). On a sunny morning in early July, Butterfly Center staff members, our summer intern, and a couple of volunteers drove out to Memorial Park armed with insect nets and containers.  While some surveys (such as birds or trees) can be done without collecting, there are so many kinds of insects (and so few experts) that at least some specimens have to be collected in order to make identifications.  

We decided to sample 10 transects — 100 feet long by about 8 feet wide — each one in a different area. Our first couple of sites were in open prairie vegetation, so we used sweep nets and aerial nets to collect samples. In case you are not versed in insect collection techniques, a “sweep net” is a canvas net bag on a sturdy metal frame that is swished through the vegetation. Periodically, the contents are emptied into Ziploc bags or other containers.

Aerial nets are the more familiar “butterfly nets”: a much lighter, more delicate net bag that is swung through the air (it should NOT be dragged on the ground, used in water, or swiped through bushes!). These nets are more for catching fairly large, individual insects, especially ones that fly, so samples are put directly into a glassine envelope, or vial, or other appropriate container (or, if it is something readily identifiable, simply noted and released). Sweep nets generally collect things like grasshoppers and katydids, walkingsticks, mantids, leaf hoppers, stink bugs, the odd caterpillar, spiders, etc. Aerial nets are useful for larger flying insects such as butterflies, dragonflies and damselflies, wasps, bees, some beetles, certain flies, etc. 

In the more forested areas, sweep nets were not really appropriate, so we used the aerial nets and also took litter samples (scraping up leaf litter and bagging it). Litter samples are typically brought back to the lab to process in a so-called Berlese funnel. Many small arthropods who live in the litter of the forest floor, including springtails and cockroaches, ants, small beetles, millipedes, etc., can be collected in this way.

 Another find in the leaf litter:  a “woolly bear” caterpillar.  This is the larval form of the Giant Leopard moth, Ecpantheria scribonia.  The caterpillar rolls up in a ball, showing red stripes between segments covered with black “fur” (these caterpillars do not sting but probably taste bad so are warningly colored).

There are many other collection techniques, none of which we used in this preliminary survey. Pitfall traps are always fun; they are empty cans or jars set into the ground with their mouths at ground level. Sometimes bait (a little raw chicken or fish, for example) is put in the bottom.

Crawling insects, especially those interested in odorous food, fall into the “pits” and cannot get out. Such traps need to be checked every couple of days — often they will contain different kinds of beetle, maybe a cockroach or two, etc.

Malaise traps are screen tents or baffles that trap small flying insects. The insects get caught in the folds of the screen and since they typically crawl upwards to escape, can be funneled into a container filled with alcohol.

Yellow pans are any wide, shallow container with a yellow (painted or otherwise) bottom.  These are partly filled with water and a bit of liquid detergent. Wasps and pollinating flies, etc., are attracted to the yellow color and cannot escape once they fall into the soapy water. Yellow pans need to be used in open areas in sunny weather and the samples removed every day or two.

Our final survey site was along the banks of Buffalo Bayou, which was much higher than usual so there was not much shore. Here, we mostly used aerial nets. We saw several things in this area that were not seen other places, especially tiger beetles, damselflies, etc. Here, we mostly used aerial nets (or grabbed things with our hands).

By noon, it was blazing hot and we were all soaked in sweat, so we bagged things up and stopped at the Shandy Café (great little place on Memorial Drive) for lunch on our way back to the Museum. 

Although we only collected for about three hours, we have our hands full in identifying everything. We first have to sort things to order, identify what we can, and then we will probably have to send some things off to experts in the various insect groups. I’m sure it will take us several weeks! 

Some of the coolest things we found: 

It’s always fun to open up the sweep net and find walkingsticks or praying mantids, or a colorful leafhopper. We picked up quite a few different grasshoppers and a few katydids.  We noted but did not catch too many butterflies (we can identify most of these by sight, so no need to collect).

I like wasps and bees; we saw several of the large red Polistes wasps, carpenter bees, leaf cutter bees, and a really cool “digger” bee starting her nest tunnel in the sand (see attached video clip). A medium-sized beetle that looked like a wasp was visiting flowers in several places. 

The very fast tiger beetles mostly eluded us down at the bayou’s edge, but we did catch a few damselflies there. The most common one there was the lovely Ebony Jewelwing.

Tiger beetles are extremely fast moving, long legged, predatory beetles that often occur in open sandy areas, especially along streams.  We saw many of these, probably Megacephala virginica – and managed to catch a few – along the bayou.  (photo from BugGuide.net by Chris Wirth)

Once we have compiled our results and reported them to the EcoTech Panel, they will then make plans for another survey sometime in the fall. I believe they intend to invite more general participation, so if you are interested in the insects of our area, keep your ears open!

The 10 Kinds of Pandas You Find on the Internet

Everyone knows cute animals basically run the Internet. But what’s the best of the best when it comes to Internet cuteness?

panda bear wallpaper 9

I hereby put forth that pandas are the epitome of Internet animal cuteness, and should reign with their ever-powerful cuteness over the masses from a bamboo throne … which would have to be replaced constantly, because they’d eat it (in an adorable fashion, of course).

Don’t believe me? Check out the 10 kinds of pandas you find on the Internet:

(Or perhaps you’re already panda savvy, in which case you should totally come see Pandas: The Journey Home now playing in the Wortham Giant Screen Theatre.)

10. SAD PANDA

Because nothing’s more adorably sad than a sad panda.

 

9. A-LIST PANDA

When you’re this cute, A-listers can’t get enough photo ops — even though the pandas obviously hog the spotlight.

 

8. PANDA SWAG PANDA

You’d wear a hat of your own face, too, if it were this cute.

 

7. HAPPY PANDA

Nothing is filled with more joy than a happy panda.

 

6. SISYPHUS PANDA

Because when the going gets tough, the tough get going.

 

5. BABY PANDA

Don’t even pretend your baby’s this cute. #SorryNotSorry

 

4. PASSIVE AGGRESSIVE PANDA

Sometimes you just need that extra push and WHO COULD EVER GET MAD AT A PANDA?!

 

3. PANDA POSERS

Everyone’s trying to rip off their adorableness.

 

2. PANDA WITH ALLERGIES

Tell me what’s cuter than a giant panda scared by a surprisingly loud sneeze from an eensie weensie panda. TELL ME.

 

1. ENDANGERED PANDA

Unfortunately, the endangered status of these miraculous creatures makes me a sad panda. However, these crazy-cute guys and gals are starting to make a come back! Learn all about the conservation programs in their native China and see how their population is beginning to rebound in Pandas: The Journey Home, now playing in the Wortham Giant Screen Theatre.

The heart of the world: The star of Jerusalem 3D talks about her hometown and seeing herself on the Giant Screen for the first time

Farah Ammouri and her brother Mohammed after viewing Jerusalem 3D in our Giant Screen Theatre for the first time.

If you haven’t yet heard the mountains of praise for the wildly stunning Jerusalem 3D movie, climb out from under your rock right now. This epic film from National Geographic Entertainment whisks and winds you through one of the world’s most important cities with arguably one of the most storied pasts of all time.

But in a city as multifaceted and layered as Jerusalem, how do you do justice to its many tales without focusing on its politics?

Well, you hear it from the perspectives of those who live it every day.

The production team of Taran Davies, George Duffield, and Daniel Ferguson said in a press release, “Our goal is to look at the roots of the universal attachment to Jerusalem: Jewish, Christian and Muslim. We hope the juxtaposition of these different religions and cultures — all with profound spiritual and historical connections to the city — will reveal how much Jews, Christians and Muslims have in common and inspire all of us to better understand each other.”

So the team asked three girls — a Christian, a Jew, and a Muslim — to lead them around their city for a day. Each girl revealed surprisingly different perspectives — perspectives that form the backbone of Jerusalem 3D‘s magic.

Farah Ammouri, an 18-year-old Muslim, was one of these young women. She spent her entire life in Jerusalem, and she currently attends college in Dallas. We sat down to talk with Ammouri after she traveled to Houston for her very first viewing — ever! — of Jerusalem 3D.

So this was the first time you’d seen the full movie. What did you think?

It was awesome. I loved it. Most of my own footage I’d seen — they’d shown me the clips of what was happening and how they were filming — so I was up-to-date on how it was going to be. But I didn’t see [any of the other girls'] footage; [Director Daniel Ferguson] only showed me mine.

How did you end up in the movie anyway?

First of all, I’m not an actress, obviously. [laughs] I went to a Catholic school, and our nun asked for girls whose families originate from Jerusalem to be interviewed for a movie. A lot of my good friends were auditioning for the movie. It was awkward for awhile, being selected out of a lot of girls that you know. I auditioned in October and I found out in January of the next year. It was a shock; I didn’t know what to expect. [Ferguson] told me about the movie; that it was going to be about religion but nothing political, and I was fascinated by the idea.

You didn’t want to be a part of it because you have acting aspirations?

Nooooo. [giggles] The girls who casted for the movie … we’re all going into something scientific. I have no aspirations to become an actress.

Did you know either of the other girls [Nadia Tadros, from a Greek Orthodox and Catholic family, and Revital Zacharie, a Jew] before the movie?

I knew the Christian girl [Nadia Tadros]. She’s really good friends with me; she used to go to my school and graduated two years before me. I didn’t know she was a Christian girl, and once I knew, we started talking to each other even more. She helped me a lot [throughout the filming of the movie]; we would give each other mental support and encourage each other.

Has your life changed at all as a result of the film?

It has given me experience. I’ve met a lot of new people, and I’ve learned a lot. My personality has gotten stronger from the movie. Imagine seeing yourself walking down the stairs [referring to a scene in Jerusalem 3D], and everyone looking at you and they are trying to tell them not to look at you. When they don’t look at the camera, they’ll be looking at me, and they tell them, “Don’t look at the girl; act normal.” It’s funny.

How do you view your relationship with Jerusalem now that you’re in the United States?

I’m a bit homesick. I do want to go back to live. I came here to study Genetic Engineering and it’s really hard to study that in Jerusalem. After that, I really want to go back home to my family.

Explore the cherished land of Jerusalem in our Giant Screen Theatre. Get your tickets to Jerusalem 3D.

Woolly mammoths to walk the earth again?

Thats right. Those giant, tusked behemoths could one day soon walk among us again. Maybe I should start at the beginning.

In 2007, a reindeer breeder in the Yamal Peninsula of Siberia named Yuri Khudi discovered a one month old baby woolly mammoth. The baby mammoth, dubbed Lyuba, is roughly 40,000 years old and almost perfectly preserved (missing only her fur and toenails.) Lyuba either suffocated by sinking in mud or drowned in a muddy river.

Large amounts of mud were found in her mouth, trunk and trachea, suggesting that she asphyxiated. This sealed out oxygen and microbes that normally break down soft tissue and helped keep Lyuba perserved. Her body then dehydrated and shrunk to about half of her normal size. Lyuba now stands about waist high on the average person. The permafrost of Siberia then covered her and kept her in pristine condition until she was uncovered 40,000 years later.

Interested? So was National Geographic. They created a documentary about Lyula, the best-preserved baby mammoth ever discovered. Waking the Baby Mammoth premieres this Sunday, April 26, at 8 p.m. Central time, and follows Yuri’s amazing find and the fascinating process of discovery as scientists work to unravel Lyula’s mysteries.  (Check out the video preview below)They investigate the body of the mammoth, learning how she briefly lived and theorizing how she died. The documentary includes CGI graphics that help show how Lyuba and her family might have looked as they survived the harsh conditions of Siberia during the ice age.

Some other things you might not know about wooly mammoths:

The word “mammoth” is thought to have originated from an old Vogul word for “earth.”

Woolly Mammoths began dying out about 10,000 years ago, around the end of the ice age. A small population of dwarfed mammoths survived in Alaska until roughly 3,700 years ago; however, the majority died out long before then.

The first largely intact frozen mammoth carcass was discovered in 1799 in Siberia.

One of the longest mammoth tusks ever found was 16 feet long and weighed more than 200 pounds.

Mammoths are very closely related to the Asian Elephant (they share 99.4 percent of their DNA.) It is possible to take the sperm from a mammoth and impregnant the egg of an elephant, and use a female elephant to incubate. This would give birth to a mammoth/elephant hybrid.

From there, it would be possible to impregnate the hybrid to create an offspring that was even more closely related to the ancient mammoths. In a similar process, you could also take a woolly mammoth egg and clone it to create  a woolly mammoth.

The woolly mammoth genome was the first genome to be reconstructed from an extinct animal It has 4.7 billion base pairs and is the largest known mammal genome.
