summer in the talley lab

another exciting summer underway (holy crap - 1/2 over!) here in the lab at University of San Diego. I am lucky to have my previous graduate students finishing up their work, another joining the lab (graduate webpage HERE), and three great undergrads in the lab, working on really interesting questions.

Alex Blanco is a McNair Scholar, continuing work in my lab, but his research is taking him in a new direction. Alex is working on an important but little-studied habitat in southern California wetlands - pools in the vegetated marsh. We are trying to better understand their distribution, and figure out if new technology (camera-equipped drones) can help us more cheaply and efficiently map these and other small-scale features in our wetlands. Of course, being Alex, he also pitches in around the lab, helping us with our other studies as well.

Yuri Bejarano also just joined the lab this summer, a transfer student from New York who is part of University of San Diego's Pre-Undergraduate Research Experience (PURE) Program. Despite the name, the PURE program, under the direction of our (great) new Director of Undergraduate Research, Dr. Sonia Zárate, now also takes transfer students, and I was fortunate to have Yuri choose my lab. She is helping me work on Fundulus parvipinnis (shocking, I know!), and is helping us get a better handle on some of the basics - ontogenetic shifts in diet; length-weight relationships; and the stable isotope signatures of females and some of their component tissues (e.g., eggs vs muscle). She is a great addition to the lab, is an amazingly hard worker and bright student, and I am looking forward to seeing the fruits of her labor!

Also in the lab this summer has been Quinn Montgomery. Quinn is on the crew team, was in my Physical Oceanography course, and is a delight to be around. He does not have a particular project he is focusing on (he has other plans for his capstone research), but has been invaluable in the field!

Of course, there has also been some great stuff going on with the Bahía de los Angeles research this summer - more on that soon!

wow - that was quite the hiatus

But I am back, with a vengeance. This promises to be another exciting semester - projects on islands in the Gulf of California; Director of the Sustainability LLC on campus; mapping local wetlands, and enjoying watching my daughter turn 7!

stay tuned....

on the border

As part of our continuing exploration of environmental, social, and fiscal implications of sustainability, a group of University of San Diego students used last Saturday to explore the Tijuana River Valley. We started with a visit to Wild Willow farm, a small organic farm operated in the flood plain of the Tijuana river. It was a very interesting visit, and we learned a lot about both how small-scale farming works and the issues related to operating in an area with a lot of migrants crossing.

From there it was off to the Tijuana River National Estuarine Research Reserve, where Chris Peregrine from State Parks talked to us about the challenges and the benefits of operating a wetland reserve where >2/3 of the watershed is in Mexico. We got to go see these important and threatened ecosystems, and had lunch at the Visitor's Center.

Finally, we headed up to Friendship Park, the small park on the border that was closed during construction of the new fence. From there you get a sweeping view of the estuary, as well as parts of Tijuana, making it an ideal spot to discuss some of the social and environmental issues that intertwine here. What made this even better was being able to talk both to Agent Kris Strickland of the Border Patrol and Enrique Morones from Border Angels (a non-profit dedicated to reducing the number of migrant deaths while crossing the border). Each of them clearly view the border issues differently, yet both stressed the need for education and compassion, and it was gratifying to see how much common ground there is when reasonable people discuss even a contentious issue.

In short, we packed a lot of learning and broadening of perspective in a single day, which is what undergraduate education is all about. Thanks to everyone who worked so hard to make this possible!

USD students learn about San Diego fisheries

last weekend a group of our students who are part of the sustainability LLC investigated issues around fisheries, food security, and San Diego. We started the trip with a visit to the docks - once a bustling center of a vast tuna fleet, now a small (but still vibrant) home to local fishers. Last saturday, the docks were loaded with hundreds of lobster traps, as the commercial lobster fishery prepared for the season opening. Our group was met by Pete Halmay, "The Urchin King", who is a key figure in the city's fishing industry. Pete explained how local fisheries can be highly sustainable and ecologically healthy, and made a compelling case for eating locally and smart when it comes to seafood. While we were there we got to visit his boat, Fish Addiction, which not only sells fresh catch of the day every weekend, but supplies many of our local restaurants with live urchin. 

We were then given a talk by the other Dr. Talley, who told us about a project she and Adina Batnitzky from USD are working on, trying to (re)connect the City Heights Somali community with fresh, sustainable seafood. 

Finally, we went to The Fish Market restaurant, where we enjoyed browsing the selection of local (and not-so-local) seafood, and sat down as a group to a delicious lunch.

The outing was a lot of fun and enlightening (not to mention delicious), thanks to the enthusiasm and hard work of Drs. Fisher, Duraij, our preceptorial assistants, students, and of course Pete!

 

me and Al Gore

I had the honor of meeting Al Gore at a recent Ocean Discovery Institute event, and even got the chance to do so with the (incredible) new Dean of University of San Diego's College of Arts and Sciences, Noelle Norton. A wonderful experience, and he is clearly a man who values education, diversity, and the sciences. 

 

Regrettably, I do not have a picture I can put up of myself with Mr. Gore, so instead here I am with one of our Ocean Discovery Institute Ocean Leaders, and you will have to imagine that she is him.

Biological Oceanography course at sea

We had our annual research cruise for Biological and Geological Oceanography here in the Marine Science & Environmental Studies department, and this year was a new collaboration with the Sea Education Association. It was a phenomenal couple of days at sea - the students got to participate in all aspects of both sailing and research, from deploying neuston nets to setting the sails; we saw lots of great marine life (whales, dolphins, pteropods, and more); and we got to meet Brad Perry from KUSI news. 

 

SEA is a fantastic program, and everyone there, from the captain and chief scientist to the stewards and deck hands was enthusiastic, knowledgeable, and eager to share information about the ship, the physics/biology, and the history of sailing and oceanography.  Plus, fresh-baked bread for our sandwiches? Crazy.

 

These pictures give a little taste of what the trip was like, but cannot do justice to what a great experience it was for our students, and how fun it is to be doing science on this ship. Now I look forward to analyzing the data and seeing what we find. 

 

back and ready for the fall!

After a summer full of travel, research, and fun, the lab is now gearing up for the fall (and feeling a little empty!). 

 

Alex Blanco is still working away at his samples, but it seems like a very interesting picture is developing about how and where the Venerupis philippinarum are invading in Mission Bay.  And Polly has a great set of photos and data for us to integrate into a field guide to San Diego fouling communities, which I hope will be used by local biologists, students, and the public.

 

Our Biological Oceanography course will be heading to sea in mid September to do some research on the SSV Robert C. Seamans, a beautiful tall ship (a brigantine) that the Sea Education Association uses. We will be accompanied by the Geological Oceanography class, and it promises to be a great trip. 

 

I also am fortunate to be in an amazing Preceptorial course - the class is Life in the Oceans, and at the risk of sounding hyperbolic, everything is phenomenal about this class. We have a wonderful Preceptorial Assistant (Maria), are part of a great Living Learning Community (Sustainability), and have some really exciting field trips and activities planned for the semester. I went over to campus today to meet some of the students and their families as they moved in, and I was uniformly impressed with how eager and excited everyone was.

 

So, the updates on the science and classes will be more regular for the next few months - stay tuned!

 

 

a welcome invasion

There is a great group from Smithsonian Environmental Research Center (SERC) taking over my lab to analyze fouling plates.  It is great to see the lab so full of activity, and to get a look at so many fascinating organisms (see pictures below). It is an added bonus that SERC was willing to hire two of our (wonderful) undergrads (Alex and Polly) to help out during the project. In fact, the organism photos below were taken by Polly, who is working on helping to create a field guide to local fouling community organisms.


Special thanks to our recent graduate and new SERCster Brianna Tracy for helping out so much while I am in CT!

travels with ducky

Some brief updates on the lab's adventures so far this summer: 

Voila_Capture.png

1. I was accompanied by my daughter's "blue eyed ducky" on the trip into Mexico - she figures prominently in many photos. 

2. Accompanied by an Ocean Discovery Institute Fellow (Rosa), Ocean Discovery Institute staff (Carla), two of my graduate students from USD (Anai and Liz), and an undergrad from University of New Mexico's Minority Access to Research Careers program (Larisa), we headed down to Bahia San Quintin for some sampling of the bivalve communities (including "sampling" some oysters).

3. After a few days of that, we drove south (stopping to enjoy some fossil beds and cave paintings) and arrived in Bahía de los Angeles, meeting up with more of my crew for Island research (Joel), the Sea Turtle research group (including Dr. John Wang and Ocean Discovery Institute Executive Director and researcher Shara Fisler), wetland scientist Dr. Christine Whitcraft, Meteorologist Jim Purpura, and other staff who somehow manage to do fieldwork, organize the station, and still keep the operation in San Diego running via super slow satellite internet.

4. My team got a phenomenal amount of work done in a few days. We set  pitfall traps on every island in the bay in three days (despite 112 degree heat and, in some cases, climbing hand-over-hand for 100m to reach the top). We also sampled the waters of the bay for nutrients, looking for pattern across a 1 km grid of sampling locations across the 25km length of the bay.

5. Meanwhile, back in San Diego, my (phenomenal) McNair Scholar Alex sampled San Diego Bay benthos with scientists from Smithsonian Environmental Research Center, worked with a student from Mater Dei High (Sergio) on sampling Fundulus parvipinnis, and managed to start his own project looking at an invasive clam in Mission Bay.

Now I am back in San Diego and trying to catch up on writing, email, bills, etc., but will update when possible!
