Bioacoustics for Reef Biodiversity

In honor of the upcoming  #WorldOceansDay  ~ this Friday, June 8th.… I thought I’d share some newly acquired knowledge…. Stay curious!

Coral reefs are hugely important ocean ecosystems that deserve our admiration and protection.  The ridiculous diversity of marine life that can be observed by just patiently maintaining neutral buoyancy in the same spot for a :45 minute dive is jaw dropping.

My niece, Katie, graduated from the University of Puget Sound with a degree in Biology. She then spent several years working as a conservation biologist in the Samoan Islands. Is that work?

Beyond the sea… Katie’s passion includes music.  A classically trained musician (piano, cello, etc. at your age), she has creatively combined her two loves: the ocean and music into hauntingly beautiful electronic compositions under her stage name, Hydrah.  Her musical art embraces bioacoustics as she weaves sounds from the coral reefs into her digital sound tracks.

Bioacoustics is a scientific field that combines biology and sound.  Our human ancestors “studied” bioacoustics for survival.  It was used for hunting prey or avoiding predators. More modernly, understanding echolocation or identifying bird songs and the howling of wolf packs might come to mind as bioacoustics being used to help us improve our understanding of the natural world.

Katie introduced me to an exciting, emerging field of research currently swirling around bioacoustics as it relates to protecting our endangered coral reefs.  Who knew this existed? Not me!  This might be an area that my sea-loving scientific students should consider for their futures… and our planet’s.

Scientists are learning that they can “listen” to coral reefs to identify and quantify the diversity of marine life living there. Using highly sensitive recorders, bioacoustic marine scientists can study the sound vibrations made by the various living organisms on the reef.  This is a non-invasive and possibly more efficient and accurate way of measuring the biodiversity of marine life on a coral reef than current methods of visually sampling and counting each organism.  Biodiversity is essential for the survival of unique ecosystems like kelp forests and coral reefs.  The diversity of life is what keeps food webs in balance.

Biacoustics could do more than just allow us to effectively analyze reef problems, bioacoustics could SAVE our reefs!  The greatest promise lies in the opportunity to record and playback these living sounds on coral reefs that have been bleached or otherwise damaged as a way of attracting larval fish and corals that can repopulate the ecosystem.   Here is a hope-filled post from a young scientist/blogger with direct experience in this budding field of bioacoustics as it relates to coral reef conservation…Reef Rhythms

And… if coral reefs inspire you…don’t miss this special opportunity to see the highly acclaimed documentary, Chasing Coral.  The Houston Museum of Natural Science (HMNS) has a one-night-only screening of the film at their Wortham Giant Screen Theatre on Wednesday, June 6th at 6pm.  Emma Hickerson, Research Coordinator for NOAA’s Flower Garden Banks and Marine Sanctuary, will be there to provide commentary about the film and to answer questions.  Ask her about opportunities to use bioacoustics to restore damaged reefs.  How could bioacoustics help our own Texas Gulf Flower Gardens?   Ticket link.

Farewell Saturn Superstar!

cassiniTomorrow, September 15, 2017 at 6:55am Central Time,  just shy of twenty years after launching, the space probe, Cassini, will end its mission by crashing into Saturn.  Cassini, you might remember from our space probe studies, has made remarkable discoveries during its time visiting Saturn.  With the help of the ESA’s hitchhiking probe, Huygens, Cassini discovered lakes of liquid methane (CH4) on Saturn’s moon, Titan, and jets of H2O erupting from its moon, Enceladus.  It has opened our imaginations to the possibility of life on Saturn’s moons.
Cassini/Huygens Discoveries

Life on Enceladus?

If I remember correctly, our friends, Steele, Adrian and Kaylie were our 6th grade experts on this hard-working, history making space probe.  I imagine they will be up early, closely watching the NASA Live Feed tomorrow morning to see their probe’s “Grand Finale” before school. NASA TV Live  I expect that this will be an oddly emotional moment for the very serious and rationale scientists that have worked for over three decades on the Cassini/Hyugens mission.  Thomas Burk, a JPL engineer that has worked tirelessly on the Cassini mission for decades was quoted this week saying:   “It’s been part of my life for so long, this spacecraft, it’s going to be a shock to have this happen,”     I wonder..  How will our experts, Steele, Adrian and Kaylie, feel as Cassini is vaporized tomorrow morning in Saturn’s atmosphere?

“Open your log book.” “Don’t forget the date!”

How many times have you heard me say the words in the title of this blog post?   I just thought I’d share that I use a science log book too!  

I’m using my log book these days for scientific drawings of the corn snake babies.  I need to make sure I can tell which baby corn snake is which.  It is important that I know who’s who so that I can keep track of each baby’s health.  Who shed? Who ate? Who made waste?  Who didn’t?   I keep the log book by their habitat.  

This drawing is of a little Okeetee that I’m calling “Torch”.


Feel free to help me out! Send me your scientific drawings of the baby corn snakes as you observe my pictures and videos. Do you have any names you’d like to suggest? 

“Herp” Fans Wanted!

It’s  been a few days since the first of Cookie and Brownie’s offspring started to peek out into the world.   Sadly two eggs are still in the incubator with no signs of hatching.  It’s not too late for hopeful thoughts but the odds of them hatching now are slimming. 

On a happier note, we do have a bunch of healthy little snakes that I have moved into their new home.   Here is a video of them moving in…


I know several of you are interested in adopting one of these cuties so today I thought I’d share how to set up a baby corn snake home. 


I have Cookie and Brownie in the 20 gallon low and long terrarium you see on the right.  It has two very sturdy locking lids.  The “locking’ part is really important as captive corn snakes have good reason to be nicknamed the “Houdini Snake”.   I bought my habitat at an awesome independent reptile shop out in Tomball: http://www.ultimatereptiles.com/

The owner and staff are extremely knowledgeable and helpful especially if you are a first time herp owner. (Herpetology is the study of amphibians and reptiles.). If you never have visited this place …. GO!!  It’s better than the zoo. 

I have all the baby corns right now in the small terrarium you see far left.  I line the floor with paper towels as they are easy to change out every few days while I have so many little ones.  You should start with paper towels too.  Later I will change to the small pebbles/sand you see in the bigger habitats.  


Above is the 50 lb bag of pebbles/sand that I buy from Pets a Plenty. (Fish R Us on 242 sells it too for $17.99) Don’t let anyone talk you into using cedar shavings as a floor material.  Too difficult to clean!! 

I like to add all sorts of cool places for the baby corn snakes to hid.  Cardboard paper towel rolls or empty yogurt cups work well.  You will need a nice light to keep your corn snake warm.  As soon as I placed the new snakes  in their new home several sped over to get a drink of water.  Hatching must make you thirsty 🙂 You will need a heavy water dish that can’t be knocked over. 

Important…. I wet a bunch of sphagum moss and put it in under the snakes’ hide structure.  The moisture makes it easier for them to shed their skin.  

Corn snakes usually have their first shed about one week after hatching and will shed every few weeks as they grow.   A few days after the first shed I can offer the baby corns their first meal.  After the babies have eaten two meals with me then I know that they are healthy and ready for a new home!

Celebrating “One Giant Leap for Mankind”

Today is the 48th anniversary of the Apollo 11 Moon landing.  This moment, 9:56pm Houston time is the 48th Anniversary of the first human foot step on the Moon.

At 3:18pm (CT), on Sunday, July 20, 1969,  Neil Armstrong successfully landed the Lunar Module (named the Eagle) on the lunar surface.  Six hours later, Neil Armstrong descended the steps of the landing module.  At 9:56pm (CT), Neil Armstrong became the first human on the moon.  He spoke these famous first words; “That’s one small step for a man, one giant leap for mankind.”   Twenty minutes later,  Edwin “Buzz” Aldrin became the second human to step on the moon.

Armstrong and Aldrin then “unveiled” a plaque mounted on the leg strut behind the ladder that had two drawings of the Earth; the Eastern and Western hemispheres. It remains there today and reads:

“Here Men From Planet Earth
First Set Foot Upon The Moon
July 1969 A.D.
We Came In Peace For All Mankind”

Video of First Steps!

The two lunar explorers spent a little over two hours collecting surface material, planting the American flag and taking photos.  They then climbed back into the Eagle and slept for several hours while their “unsung hero”, Michael Collins, continued to patiently orbit in the Command Module (Columbia).  On Monday, July 21st at 12:54pm Houston time the upper stage of the Eagle blasted off the surface to rendezvous with Columbia.  After a three day return journey covering 200,000+ miles, on July 24, 1969, the three astronauts splashed down just before dawn in the Pacific Ocean 825 nautical miles SW of Hawaii in the Columbia capsule.

On this day, 48 years ago, Armstrong and Aldrin became the first of only 12 humans (all men, all Americans) to walk on the moon.  Those 12 men are the only humans to ever leave Low Earth Orbit (LEO) and step on another natural object in space.

Mankind has not left LEO since the last Apollo Mission (17) in 1972!  No rocket as powerful as the Apollo missions’ Saturn V has been launched since 1972.   However, those “fun facts” are likely to change in our lifetimes…..

Interestingly, a remarkably similar photo to the one above, appeared in the Houston Chronicle just last week (below).  The photo however was not a celebrating a past NASA mission but instead was from recent NASA maneuvers in the Gulf to practice astronaut exit procedures for the new ORION spacecraft.
