Farewell to fish tails...

Now that I have returned home safely and jumped right back into work with the Forest Service I figured it is about time to reflect on my final thoughts from Australia and wrap up the fish tails until my next adventure!  Just about 6 months ago I arrived in Australia without a place to live, not knowing anyone, and not much of a sense of what to expect at work or where work (or anything for that matter) even was!  Since then I have vastly expanded my professional scope of skills and experiences, made amazing friends, travelled a beautiful country and had opportunities to try all sorts of new things from SCUBA diving to vegemite to hang gliding.  Although the NMSC offered an atmosphere that could leave some feeling lost at first, and unsure of what projects to jump into or what initiatives to kick off, it was perfect for a self-driven intern and employee like myself.  Specific tasks that I needed to accomplish on a weekly basis were outlined but the rest of my time was driven by my research interests as I had a large say as to which researchers and projects I would be working with so that I could be both useful to them as well as take advantage of the vast learning opportunities.  I spent the majority of my time working in the Ocean Acidification Lab, Aquaculture Facilities, Bycath Reduction, Marine Organisms Genetics (specifically mollusks), Scuba fish and coral surveys, as well as working some weekends in the aquarium giving fish talks and I even dabbled with a little bartending (outside the center that is).  I was able to dive at least a few times a week, spend time in the field, on research vessels, commercial fishing boats, in the lab and in the aquarium.  This multiplicity of experiences was what I appreciate most about my time in Australia as it helped me to exceed my primary goal of diversifying and expanding my range of fisheries research experience, specifically to from freshwater to marine environments. 

The most valuable advice I could give to future students interested in such a program is to go into the experience with an entirely open mind and take advantage of any opportunity that comes your way.  Working, interning and travelling abroad helped to grow personally and professionally on many levels.  I found the experience to be immensely fulfilling as well as opening up so many opportunities for my future career.  Many thanks to everyone that has helped to make this wonderful experience possible! Until my next adventure, this is all for Fish Tails (from Down Under)……………..

The Final Aussie Adventure

Needless to say my final weeks in Australia were a hectic few, scrambling to finish up the mollusk collecting and dissecting and wrap up all other remaining projects at work as well as trying to squeeze in one last adventure to explore the Great Ocean Road and Melbourne.  There were quite a few late nights in the lab but we successfully obtained tissue samples from a wide range of mollusk families at a variety of eastern locations.  The samples are all packed in their microplates and ready to be shipped off to Canada to have their barcodes read!  The main challenge we encountered was trying to preserve the shell for taxonomic records of each tissue sample we collected, in many cases we simply had to smash the shell to obtain the tissue.  As the first primary marine mollusk collection for the Barcode of Life we anticipated encountering some challenges to work through and hoped to use our experiences to create a standard protocol for future collections so I consider it a success and am thrilled to have gotten to the initiative going, as it will continue on at the Marine Center until no mollusk is left behind!

                Beyond the late nights in the lab I was also able to squeeze in my trip to Victoria.  We flew into Melbourne, at which point we rented a Wicked Van (fully equipped with road trip camping essentials and raunchy slogans and paintings all over it) and set out on the Great Ocean Road.  The drive was amazing as we headed west along the Victorian coast line and stopped at the iconic spots such as Bells Beach and the 12 Apostles and some quiet spots for some great hiking and more koalas than I ever would have imagined seeing in the wild.  On the return drive we took a bit of a detour to Lake Elizabeth which is known for its platypus sightings, but after many hours of traipsing through the rain in search of platypus I finally had to accept that I wasn’t going to get to cross “seeing a platypus” off my bucket list just yet (which gives me more of an excuse to head back to Australia sooner than later I suppose).  I was however fortunate enough to get to see a colony of fairy penguins as we made our way back to Melbourne; and still had time to visit the aquarium, casino and museum before I returned to Coffs to pack up and say my final goodbyes.  All in all, it was a great little adventure to wrap up the enormous adventure that my time in Australia has been! 

Grey Nurse Sharks

Finally Made it to Manta Arch and Shark Gutter at South solitary over the weekend to check out all the endangered Grey Nurse Sharks! The season to see these amazing creatures is just beginning to pick up as the water cools down.  We saw around 10 nurses on our dive (approximately 25 to 28 m depth) but as winter progresses is not rare to see about 20 together at one time.  Grey Nurse Sharks are critically endangered and were the first protected shark species in the world.  They grow to about 3.5 meters in length and were nearly hunted to extinction as they were thought to be ferocious and responsible for human attacks due to their size and appearance (they are actually not aggressive sharks).  Even though deliberate killing has been banned they still face many threats including shark netting on beaches, commercial fishing trawling, bottom set fishing lines and finning (cutting off of shark's fins for human consumption, illegal in most areas now but still prevalent).  Additionally, they do not reach sexual maturity until they are 6 to 8 years old giving birth every other year to 1 or 2 young, this slow maturity increases their susceptibility to population decline.  Marine sanctuaries, such as that in the Solitary Islands, aid in protecting breeding and feeding grounds, ban fishing and collecting and impose conduct regulations for diving with Grey Nurses.   However, without accurate population estimates (estimates range anywhere from 300 to 1300 individuals) or widespread management plans to assist in their recovery they are still greatly at risk for extinction.

Reflecting on Goals... Part 1

      When submitting a proposal to OSU to have a work site/ program approved for internship credits a large part of the process included developing professional, personal and cross cultural goals for the time abroad.  As I was answering a series of check in questions for my advisor I couldn’t help but to reflect on a funny experience I encountered with one of my personal/ cross cultural goals.  One of my goals was to learn to use the public transportation systems of Australia to be able to get around and between the cities and actually know where I was going.  It sounds like a simple thing to learn but the extent of my bus riding prior to coming to Australia was taking the school bus my freshman year of high school and the last (and only) train ride I had been on was probably the scenic tour ride of the Gorge.  My first experience on the train was just from Coffs Harbour to Sydney Central and then switching trains at Sydney Central to hop on the one that runs to the airport.  All went well and I figured out what trains went where from what platforms and how to get around the city.  All in all, Sydney Central was not nearly as bustling and crazy of a place as I had thought it would be.  Feeling good about having taken on Sydney, I figured Brisbane and Cairns would be no problem.  This time I even took a few busses to get around and made it there just fine, but it was on the way back that I must have gotten a little too cocky about my new found skills.  I was taking the train in Brisbane from my hostel to the airport to return to Coffs.  It was clearly morning commute time for all the business professionals of Brisbane dressed in their suits, meanwhile I had just hopped off the live aboard dive boat, ran out of any form of clean clothes days before, and just had my back pack with some dive gear and dirty clothes at this point.  The train I wanted to catch was just about to leave as I got up to the platform and even though I knew there was another train going exactly where I needed to go 4 minutes later I thought I’d dash on and give it a try.  I made it on but the doors closed on my backpack I was wearing and thus I was stuck in the door because I could not wiggle out of my back pack.  I flailed around like a turtle on my back for awhile trying to push the giant red “door open” button that was just out of my reach meanwhile everybody just stood and watched until I finally asked someone if they could push the button for me. When they begrudgingly did the door finally opened and I was unstuck from it and flung forward.  Needless to say it was definitely an embarrassing train ride but at least now I know what all of the posters around the train station mean when they say “it is safer to wait for the next train”.

More on Mollusks

      Mollusk collection has finally begun in full force.  Beyond general surveying to examine mollusk range as an indicator species for greater issues such as sea level rise, biodiversity loss in increased temperatures, sensitivity to pH levels etc... we will be extracting DNA samples for genetic analysis for the Barcode of Life Initiative.  Obtaining this genetic data will define species boundaries which can be difficult due to solely based on morphology due to phenotypical variation. Thus a baseline catalogue of of species will become accessible which is essential to identify what exactly it is we are trying to conserve.  All data is gathered into the worldwide BOLD database which offers morphological and geographical data on the species in addition to the barcodes.  As the database grows I think it will be interesting to examine the ecophenotypes and genetic variability by region offering insight into their evolution and species delimitation.  As a strong database continues to develop it will have many additional uses such as determining the diets and trophic levels of organisms by doing gut samples and obtaining DNA from the prey in the stomach and intestines and thus identifying exactly what it has eaten by matching barcodes from gut contents to barcodes in the database.  This would me much more accurate and easier than current gut analysis techniques as the food that is too digested to be identified normally could still be identified by obtaining DNA that would still be extractable.  Another increasingly common application of DNA barcode information is using it to crackdown on seafood fraud which has become more prevalent in recent years.  Currently the FDA is utilising this information and it is likely that other agencies will begin to as well given the success the FDA is having.  As the database becomes more complete (it encompasses all species not just mollusks, mollusks are just the category that is most in need of genetic analysis currently) it will become more widely utilised for a range of research and practical applications.

     Within the next month we are hoping to collect 200 species of mollusks with 2 specimens of each species.  Last Wednesday's collection yielded approximately our first 30 species from rocky shore habitats at Mulloway Beach and Thursday was a day of diving to survey South and Split Solitary Island's mollusks and collect on the third dive at Muttonbird Island.  Unfortunately currents were strong and visibility dropped from about 12 meters at Split and South to 1 meter at Muttonbird so we were only able to collect about 10 species.  This week we did a rocky shore collection from Woolgoolga and I was fortunate to have the help of a few of Steve's (the head mollusk researcher at the NMSC) third year marine science students to turn some boulders and search for mollusks.  We found another 20 or so species we had not yet collected but I was worried we might lose a couple when the guys thought it would be funny to put an octopus in my bucket of samples, needless to say octopus love eating mollusks.  It all worked out in the end despite an angry octopus spraying me with water and causing a scene while trying to get it out of the bucket before it ate any samples.  After the slight ordeal, I still have plenty of mollusks from the last 2 weeks to keep me busy for awhile. Collecting will prove to be the easy part;  After getting some photos for each specimen they go into 95% ethanol until I will have time to dissect them in the lab.  I have to obtain a tissue sample without contaminating it with any contents from the stomach or intestines in order to get a clean DNA sample.  For bivalves it is supposed to be ideal to sample from the adductor muscle and for gastropods just behind the operculum but the smaller the mollusk the harder it becomes.  I have a feeling by it is going to take all 400 samples to master the best technique! 

I will try and get some mollusk photos up soon!
