Conservation On-Site: The Mountain Yellow-Legged Frog

by | January 29th, 2014

As you visit Oakland Zoo this winter and spring you may notice that the animals and projects we are supporting at our Quarters for Conservation booth in Flamingo Plaza have changed.   I would like you to pay special attention to the developing partnership with the San Francisco State University Mountain Yellow-Legged Frog project.   This project teams up Oakland Zoo with San Francisco State University in bringing awareness to and supporting the recovery of this critically endangered species that is found right here in the mountains of California.

Yellow-legged_frog_Point_Reyes

Once one of the most numerous species found in their alpine habitat in the Sierra Nevada, Transverse, and Peninsular ranges they are now one of the rarest despite this habitat being found in some of the most well-managed and inaccessible areas of the state.    During some of the initial research looking into this decline the focus was on the impact and removal of game fish that were introduced to their alpine habitats, such as trout.   The Mountain Yellow-Legged Frog evolved in a habitat where such efficient predators were not common and the eggs, tadpoles, and frogs themselves became easy prey.  With the management and removal of these introduced fish species some areas showed rapid recovery of frogs.    However, some did not, and in fact the overall population continued to decline.    The emerging disease known as the chytrid fungus (Batrachochytrium dendrobatidis) was found to be the cause of this continued decline and was attacking the frogs during one of their most sensitive transitions in life, the one between tadpole and juvenile life stages.    The chytrid fungus works by attacking the keratin in the skin of juvenile and adult frogs preventing them from being able to use their skin to respirate and exchange water leading to their deaths, wiping out whole populations.   For some reason the disease does not affect the tadpoles of the Mountain Yellow-Legged Frog, but it will remain with them through the several years they spend as a tadpole.    This makes the tadpoles, along with several other frog species that are not affected, a means to not only infect their own kind with this deadly fungus, but to make it almost impossible to eliminate from the environment.

With this revelation the focus to save the Mountain Yellow-Legged Frog changed to not only manage and remove non-native fish, but to support the frogs in gaining resistance to the chytrid fungus during this transition in their life.   The support comes in the form of a bacterium called Janthinobacterium lividum.    The bacteria was discovered on the skin of a fellow amphibian, the red-backed salamander, and later discovered to also be present on the skins of Mountain Yellow-Legged Frog in varying levels.   This bacterium has the unique feature of having anti-fungal properties and when found in greater numbers on amphibian skin can help to increase resistance to the chytrid fungus.    Now, in steps Dr. Vance Vredenburg and the San Francisco State University Mountain Yellow-Legged Frog Project.   Dr. Vredenburg has been pioneering skin bio augmentation treatments using Janthinobacterium lividum to support juvenile frogs that are being rereleased or will be re-released into their habitats in both Northern and Southern California.     Through a partnership with San Diego Zoo, San Francisco Zoo, and soon Oakland Zoo, San Francisco State University is hoping to tip the balance for these frogs by collecting them as eggs from their habitat, hatching them in captivity, raise them to juvenile frogs, treating them with this anti-chytrid bacterium, and release them back into their natal ponds and streams.   It is hoped that not only will this prove to provide long term resistance to chytrid, but will be naturally passed between frogs as they naturally congregate together in the shallows off the banks of the rivers and lakes they live.

If you are interested in learning more about the plight of the Mountain Yellow-Legged Frog and supporting them as well during their most vulnerable transitions you can join us on Wednesday February 5th at 6:30 p.m. in the Marian Zimmer Auditorium at our Conservation Speaker Series event when Dr. Vance Vredenburg joins us to discuss his work with the Mountain Yellow-Legged Frog and the implications his research has to save this and potentially numerous other amphibian species worldwide.

PARENTS GET A “TIME-OUT”

by | January 28th, 2014

Hey Parents!parentnightout

Need a fun place to leave the kids while you go out and enjoy some time alone with your sweetheart on Valentine’s Day? Look no further than Oakland Zoo. Starting this year, the Zoo is offering a fun new program called “Parents Night Out” that might be just what you’re looking for. But it’s more than simply “babysitting at the Zoo” – geared for children aged 4 to 10 years, this program offers a full evening of entertaining animal-themed fun. Once you drop off your kids, you can rest easy knowing they’re having a good time and being well taken care of. They’ll start off enjoying a pizza dinner, followed by a cool guided walk through the Children’s Zoo to visit animals such as alligators, bats, turtles, frogs, lizards and bugs. They will even get a sneak peek at where the ZooKeepers prepare the food for all the animals of the Zoo. Later, in the auditorium, your kids will be able to participate in a fun game or craft, followed by an ‘animal close-up’, where they get to meet an animal up close and personal. Then, we top off the evening with an exciting animal-themed movie. All this for $30 per child (plus $25 for each additional sibling.) Not bad to ensure some quality couple time on Valentine’s Day.

You can drop off your kids at the Marian Zimmer Auditorium at 5:30 in the evening and stay out till 10:00pm, giving you a full evening to “get away from it all” with dinner, dancing, a movie, or a romantic stroll. And when you come back to pick up your kids, they’ll have plenty of exciting things to share about their evening at the Zoo. And if things take off like we’re expecting, we’re hoping to expand our Parents Night Out program on selected Friday or Saturday evenings at other times during the year. So if you want to have one of those special Valentine’s Days like you used to have, give Oakland Zoo a call and sign your kids up for “Parents’ Night Out.” Then, go out and hit the town. We’ll see you when you get back!

 

Fulong Means Forest: Our Time with Sun Bears

by | January 3rd, 2014

Time with Bears:

Fulong means forest in Lundayieh, a tribal language in Borneo. A tiny sun bear cub, the smallest of all bear species, was found in the forest by a hunter’s dog and brought to the master who gave him the name Fulong.  The man kept the bear in a cage as a pet — but when he found out he could give her a better life, he relinquished her to the Bornean Sun Bear Conservation Centre, where we sat this morning in rapt attention as Gloria, the head of education, told us the history of some of the beautiful sun bears at the centre.Bear2

Sun bears and the work of Siew Te Wong was our inspiration to embark on a conservation expedition to Borneo in the first place. We have been in full support of his efforts to give a wonderful home to sun bears that all have a different conservation back story. This new center is right next to the Sepilok Orangutan Center and sure to be a hit. Many visitors to Borneo know about Orangutans, and now many will know about this amazing bear.BearGifts

After six years of helping Wong work as the founder and raise funds for this center, it is a THRILL for our group to be here to help them get ready for their soft opening to the public in January. After a survey of our skills and their needs — Gloria and I put together a schedule – and we rolled up our sleeves and got to work!IMG_7531

What a day we are having! In the rain and heat, one group is moving gravel with shovels and wheelbarrows, watching for venomous snakes and tiger leeches. Another is in the bear house, chopping diets of banana, papaya, green beans – and heating an oatmeal-like super nutritious bear meal. Some even enjoy cleaning the night houses in this sparkling new facility.IMG_7523

Carol and Jereld are off with Ling Mai to set up camera traps. We then work with her to create a matrix for observing bears which we will try out this afternoon. Diana then helps create a program to illustrate the data that will be gathered. Carol and Rob sit together at a laptop editing copy for the educational signage for hours and hours, quite happily. Tina then gives her ideas around signage design. We hardly want to break for lunch, but we do, ‘cause it is hot and we have worked up quite an appetite.IMG_7650

After lunch with the bear staff, Lovesong and Mary go off with the bear keepers, exchanging stories and ideas on how to best care for a sun bear. A crew works with Gloria to envision the visitor center’s future displays and interactives. Another crew gathers around Ernie to discuss the gift shop and other ways to bring in extra funds to the program. Apparently t-shirts and postcards are the big sellers, but creativity is flowing. I get to download about education programs, volunteer positions and conservation action and messaging. I also got the pleasure of taking portraits of the staff for their website.
IMG_7658As the afternoon rolls along, I feel so fortunate to have gotten to be here on this day atthis time in the center’s history. What a joy to share what we could with them, and how inspiring to meet this talented and dedicated staff who shared so much with us. We are all lucky, especially bears like Fulong!

 

Holiday Gifts for the Animals

And our sun bears love Kongs. Sometimes, we even fill them with peanut butter, which is the sun bears’ favorite thing to eat.

Hey Kids! Zena the Zookeeper here.  It’s holiday time at Oakland Zoo, and I have a question for you: Name something you love getting during the holidays. If you said, PRESENTS! then you and our animals here at the Zoo have something in common.  Our animals love presents too.  And I’m here to tell you, we just love giving presents to them.  The presents we give our animals are called enrichments.  Those are special toys and games that help our animals live like they are back in the wild.  (If you want to learn more about animal enrichments, check out my blog from September called Animal Enrichment is Important to Chimpanzees!)

So, what kinds of presents do our animals like to receive? All kinds! Our chimps love lots of different toys. For example, one of our female chimps just adores plush-toy snakes. She wears them around her neck like a scarf. The ferrets and chinchillas love hanging beds, and the zebras go nuts for Jolly-Ranger balls.  We zookeepers put treats in the balls and watch the zebras happily work to get them out! Check out the picture here of my fellow 20131002_143235zookeeper prepping the balls with molasses and alfalfa for the Zebras to enjoy.20131002_144428

And, just last week we asked people to send presents for some of our Zoo staff headed to Borneo to help out some rescued sun bears over there.   And boy, did everyone help out! We got so many new toys for them – we even have some pictures of the Bornean bears playing with their new presents from Oakland Zoo.

If you’d like to give a present to one of our Zoo animals this holiday season, be sure to check out the wishlist we zookeepers put up on amazon.com .  It lists all the great toys and enrichment we know our animals love to receive.

 

The goats in the Children’s Contact Yard love butting around big, inflatable balls.  I suspect they may be playing some kind of top-secret goat soccer!

There’s lots to choose from, so I’m sure you’ll find something that will make one of our animals feel wild and wonderful.(Don’t forget to check with an adult before you purchase anything.)

So, until next time, remember – we only have one planet, so let’s all be conservation heroes and take good care of everything on it!

Attention Future Biologists!

by | November 11th, 2013

MollyAtBeachHave you ever wanted to know what it’s like to be a real field biologist, studying wildlife in the great outdoors? What exactly do they do out there with all that cool equipment, anyway? Now, there’s an easy way to find out. Oakland Zoo is proud to introduce its latest educational program, the Field Biology Workshops, where we focus on modern, innovative techniques of field biology and conservation. If you’re a middle or high school student, this could be your opportunity to try your hand at this rewarding career while you’re still in school. And you don’t even have to go anywhere—the Zoo brings it all to your classroom.

The San Diego Institute for Conservation Research (ICR), who offers a summer program for science educators looking to institute their own science programs, was instrumental in helping to get this program off the ground. During a three-day conservation institute for teachers held by ICR, members of the Zoo’s education staff had the opportunity to learn the curriculum and were provided with teaching materials to get started

Here’s how it works. During our engaging one or two-day in-class workshops (an hour each) you’ll get the chance to use modern technology to study wildlife, analyzing real data collected in the field. A good example is with our condor program, the field study that uses GPS technology to track endangered California condors released back into the wild in Baja California and the Ventana Wilderness Area near Big Sur. As a young aspiring scientist, you’ll be asked to analyze data and give thought to the conservation challenges that these animals face in the real world. Using satellite mapping techniques, you’ll study and analyze the condors’ geographic range and make your own decisions about ways to protect it. One of the exercises involves the planning for a proposed wind farm within the condors’ habitat. Based on your analysis of the data, your job is to advise the company on the best place to locate the facility to minimize risk to the birds while still serving the needs of the public.

One of the goals of the Field Biology Workshops is skill-building. We ask the students to come up with answers to these problems; not necessarily focusing on the right answer, but getting the students to think and work like a scientist. Through this program the Zoo is hoping to expand its educational reach by bridging the demographic between its ZooSchool, Teen Wild Guide and ZooMobile programs, offering educational services to students in middle and high schools. The program is still in the planning stages but we’re hoping to be up and running this school year. To find out more about the Field Biology Workshops, please call our Teen Programs Manager, Melinda Sievert at (510) 632-9525 ext 201. So if you’re a middle or high school student who’s interested in biology or if you know someone who is, give Oakland Zoo a call and get that young scientist onboard with the new Field Biology Workshops. See you at the Zoo!
