The Lionesses of Lafupa


The Lafupa Pride - here showing two of the three females we witnessed stalking a mixed herd of zebra and hartebeast. The lady in the back is likely pregnant, and didn't take part in the hunting activities, choosing to stay in the nice shade instead! This hunt was unsuccessful.

The lions are nearly invisible out here, with their coloration as well as their behavior. They can be bedded down in the grass, taking a siesta...and you can drive right up to them without a response. So if you decide you need to stop and take a pee, and you didn't detect them, you may regret it.

The Packing Begins


The challenge: pack almost 50 VHF collars in checked luggage along with all our personal items, staying under the required weight (50 lbs), and not getting arrested because we appear to be smuggling expensive items into the country to be sold!  The line of collars in the far back are for wild dog and cheetah, the middle row collars for lions and hyenas, the front collars for wildebeest.

Many already know, but for those who don't, I successfully completed my Master's degree at Montana State University (what a relief!), and have accepted a position with the Zambian Carnivore Programme, where I'll be stationed in Kafue National Park studying most of the animals that are capable of eating me. I'm leaving May 19th, and will be in Zambia for approximately 7 months, returning in December-ish (with a quick return in Aug for my roommates', Aaron and Amber's, wedding!).

Stay tuned for more....

Defended

The reason for the two year silence (wow, I can't believe its been over two years since I've posted on here last!):

A Friendly Penguin Wave (Goodbye?!)

The 2012 Weddell seal science season for our crew is just about wrapped up, sadly enough.  Our camp has been pulled off the ice, and we've been busy scurrying around, returning equipment and gear, cleaning and washing everything.  We leave in 7 days!  Aaack!

It has been an incredible season with a lot of valuable data collected by a solid crew.  There are literally hundreds of people to thank for making this project a success...a substantial proportion of them working as support staff here on station.  Nothing would be possible without their wonderful and friendly support.  And I certainly can't forget to thank YOU (if you are a tax-paying American citizen).  Because this project is completely funded by the National Science Foundation, YOU are paying for it.

This may be my last season here on the ice, and so I hope you have enjoyed some of my attempts to capture not only the project, but also the incredible scenery and majesty of this place.  I may have a few more posts left in me, and then I predict Aspiring Ecologist to go silent for an indeterminate period.

A big, final THANK YOU to all my blog followers!  I received so much encouraging feedback, which helped me to keep at it, and I'm stoked there is so much interest in the Antarctic and the seals.

To the elementary classrooms that have been following along, THANK YOU too!  Keep admiring the world around you...even in your own backyard, there are incredible examples of how diverse, complex, and beautiful the natural world is.  And nothing is better to lift the spirits than to waddle around like a penguin for a bit.  Or even a seal if you can manage it.

Adios Amigos!

The Pack Ice is In

The sea ice edge transformed by fast flowing pack ice and peculiar penguins:

White Islanders

About 60 years ago, the sea ice melted so far back into McMurdo Sound, that it began melting and breaking off the ice shelf all the way back to an island, called White Island.  Previous to this event, no seals were found at White Island, but the melting allowed several (estimated to be three females and two males based on an ongoing study by Tom Gelatt) seals to get to the island and take advantage of its underwater resources (food!).  But the seals did not prepare for the fact that they would never be allowed to leave again.  The next year, and every year after, even to the present time, the sea ice has not melted or broken out to White Island, and the ice edge has always been maintained at a distance too far for the seals to make it out.  So the seals have remained, and they have kept breeding.  Each season, we take a helicopter twice to White Island to tag any pups that are born, collect genetics samples (a tiny tissue sample from their flipper), and assess their status.  Since it is a small population, inbreeding is basically guaranteed and even though they seem to be doing just fine when we show up and tag a couple pups, there is a high degree of inbreeding depression (fancy way of saying decreased fitness, or reproduction in this case, because of low genetic diversity).  But they do keep breeding, and they do keep recruiting.  In 2000, the total population was estimated at 27 individuals (10 males, 17 females).

I wish I had more recent figures than that (figures come from a paper published by Gelatt et. al. 2010 "History and fate of a small isolated population of Weddell seals at White Island, Antarctica"), but this year, we tagged three new pups, and probably saw about 10 seals on the ice...which really says nothing because there are probably many more seals below the ice.  It is a very interesting population, and a great example of isolation occurring naturally, which we can then, thanks to multiple visits per year by the project, keep track of population dynamics to see what its doing, and possibly where its headed.

North shore, looking back towards Ross Island (Mt Erebus to the left, McMurdo is located outside the photo further left).  Between White Island and Ross Island, it is an expanse of ice shelf glacier coming down off the continent to the sea.  That is basically the distance a seal would have to swim to get out.

The Edge

A helo flight to Marble Point (to tag pups from mom's that were previously tagged and retag any adults that needed it), brought us along the edge of the sea ice, where some pack ice has been blown in.  I have never seen this before, typically (the past two seasons being typical for me), it is just vast open ocean.  Pack ice tends to bring more critters, as some, like the leopard seal, crabbeater seal, and Ross's seal, are much more tightly associated with pack ice.  Here are a few shots of the pack ice:

Comparative Fat Content Analysis

...a real science-y way of saying "Look at how fat that pup has gotten!"

Before:

About 70 pounds.

After: 

Pup is on the left (!)  About 270 pounds.  See how the mom diminishes as well.

Blubbery fatso (that's a compliment)

Chubs sleeping in a collapsed cornice
Working amongst the fatties.  Note the seal behind Jason...thats a mom whos been nursing for about a month...she used to be quite rotund, now you can see her shoulder and hip bones now that the pup has incorporated all her mass.
