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!

 

The Majestic Elephants at Oakland Zoo…

by | January 21st, 2014

Often, we at the Zoo are asked about the history of our majestic and beautiful African elephants. In her blog below, Gina Kinzley, Oakland Zoo Elephant Keeper, shares a little of the history and personalities of Donna, M’Dunda, Osh and Lisa. Now that you know them a bit more intimately, come to the Zoo and say hi! You can also see how Gina ‘trains’ our elephants to for situations involving medical procedures, foot-maintenance, and mental stimulation exercises in this video, filmed recently.

The African Elephants of Oakland Zoo:

All of the girls come from Africa originally, but their families were killed in a culling. Culling is the very controversial method of population management. At that time, the young orphans were caught and sold for profit, which is how they ended up in the United States. I won’t name the previous facilities that they were all at, but all of them have a history of abuse in ‘free contact’ management. At Oakland Zoo, we practice ‘protected contact’, as we explain is for the safety of the both our elephants and their keepers, in the HBO documentary “Apology to Elephants”.

Donna, 34, came to OZ in 1989. She very quickly became the the dominant female because she had the biggest attitude. She is the most playful out of the girls and loves to have big play bouts at nighttime with large tractor tires and will charge into the pool for a cool down! Personality-wise Donna is impatient, loves to participate in training, and is closely bonded with Lisa, whom she sleeps with every night.elephantpedi

M’Dunda, 44, came to OZ in 1991. She has a bad history of abuse at her previous facility which is amazing because she is an extremely gentle soul and wouldn’t hurt a fly. She loves to solicit play from Osh, and is often spotted at night over the fenceline trunk twirling with him. She can be a little insecure, and scared of new situations. When she first came here she wouldn’t eat her treat boxes! She also has long beautiful tusks.

Lisa, 36, has been at OZ since she has been two years old. She came from Kruger National Park in South Africa and went briefly to a “training” facility for several months then came to the zoo. Lisa is an elephant’s elephant, she likes all of her pachyderm friends, and wants to make everyone happy. She loves her pool, we call her our water baby, and will take daily dips if the weather is right! She is sneaky, agile, and can be very stubborn!

Osh, 19, has been at OZ since 2004. He came from Howletts Wild Animal Park, where he was born and with his family group. Young males in the wild get kicked out of their herd from ages 8-12, and that is what Osh’s mom and aunts started to act toward him, so we gave him a home here. Osh is extremely active, exploratory, and curious. He’s got a very lively and chipper walk, loves to play, browse and graze.

At Oakland Zoo we care deeply about the well-being of elephants in captivity, as well as their conservation in the wild. Currently 96 elephants a day in Africa are being killed for their tusks, or ivory. Now that you’ve learned about how intelligent, unique, and beautiful our elephants are here at the zoo, please visit www.96elephants.org for more information on how you can help elephants in the wild. This issue is very important to us, and increasing public awareness is a priority. Stay tuned over the coming months for more information about the fight against the illegal ivory trade and the work of www.96elephants.org.

Food favorites: Pumpkins, Melons, and Pineapples. Want to feed our elephants? Come to our next Feast for the Beasts event on March 29th!

 

 

Holiday Gifts for the Animals

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!

Toys needed for Sun Bears in Borneo
(Oakland Zoo Conservation Program)

The Bornean Sun Bear Conservation Centre, located in the Malaysian state of Sabah on the island of Borneo, rescues sun bears and seeks to rehabilitate bears that may be suitable to return to the wild.

 

Most of the 28 bears in residence at the Centre are victims of the illegal pet trade….mother bears are killed by poachers for their body parts (paws, bile from the gall bladder) and orphaned cubs are often captured and spend their lives in small bare cages without adequate space or proper diet. Many of the bears at the Centre have never walked on grass or been able to climb a tree, a tragedy for these very arboreal bears. The Centre currently has one new bear house built in

A visitor centre, viewing platform and guest walkway connecting visitors with nearby Sepilok Orangutan Rehabilitation Centre, are all due to be completed in early 2014. Please visit the BSBCC website at www.bsbcc.org.my to learn more and find out how you can support the extraordinary work being done to save the world’s smallest bear species”.

Through our fundraising efforts, our support of the BSBCC helps to fund completion of the much-needed rehabilitation facility in Sabah. Oakland Zoo’s own veterinarians have travelled to Malaysia to provide hands-on assistance in moving and providing medical care to the Sun Bears currently being rehabilitated by the BSBCC. Now, on October 31st, Oakland Zoo staff is leading a trip to Borneo very soon and they will be visiting the Bornean Sun Bear Conservation Centre. The bears at the center have been rescued as orphans due to poaching and often from the illegal pet trade. In fact, our bear, Ting Ting, was one of those cubs as were both parents of Bulan and Pagi.  The staff at the center would love to be able to provide their bears with “Kong” toys such as Pagi is enjoying. Here at Oakland Zoo, Pagi Bear is enjoying her “Kong” toy enrichment. and our zoo travelers are willing to pack such toys in their luggage for the trip.

Can you help out the bears at the Bornean Sun Bear Conservation Centre by purchasing an Extra Large “Kong” toy to send along with them?

You may purchase these and more on Amazon.com.  Just click here for the items specifically requested for the bears and make sure it will arrive by October 31st.  Thank you for caring about sun bears.

Marching for Elephants . . . Join Us!

If you haven’t seen a flyer around town, or a kind face at a table in front of the elephant exhibit at Oakland Zoo to spread the word, I am here to tell you about a very important event that is coming soon. The International Elephant March, created by the iWorry campaign at the Daphne Sheldrick Wildlife Trust, is going to be held on October 4th worldwide! The Daphne Sheldrick Wildlife Trust, or DSWT, is a non-profit who takes in all of the orphaned elephants that lose their mothers and families to the devastating poaching that is currently taking place. There are over one dozen official DSWT sponsored cities that are taking place in the march, and because there are so many people that care, there are now an additional twenty cities worldwide that are hosting a march as well, including San Francisco. Ivory poaching is nothing new, in fact in 1979 there were still 1.3 million African Elephants living, but by 1989 well over half of that population was wiped out due to a demand for their ivory, or tusks, which left a remaining 600,000. In that same year, a ban on selling ivory in Africa was created, which significantly helped to halt the trade. Elephants were left to be in peace . . . mostly. What remained were stockpiles of tusks in many countries in Africa, and with the unfortunate decision to allow a few countries to conduct a one-off sale of these stockpiles, opened up the floodgates.

In China, a sign of wealth is to own ivory, and due to a growing middle class, there is a high demand.

With gangs of poachers who are getting more and more sophisticated with their artillery, corrupt African governments, and the high demand from China,  elephants don’t stand a chance . . . unless we come together and make a change. Slowly, the issue is receiving more press and getting attention from politicians and movie stars. Prince William, David Beckham, Yao Ming, and Leonardo DiCaprio are just a few. The Clinton Foundation are strong supporters of the issue, and President Obama recently has put aside a task force, along with a ten million dollar fund to help stop wildlife trafficking. These are steps, but we need MORE! The more awareness we can create the better, especially amongst youth. When tabling at the zoo, I found that there are a lot of people who think that elephant tusks are just cut off without any harm and that they grow back or that they just fall out like our teeth. This is a huge misconception and according to a study by the International Animal Welfare Foundation that was conducted in China, 70% of Chinese people did not realize that ivory comes from dead elephants. If we can create awareness through social media and campaigning we may have a chance at turning things around for elephants. If we stop the demand, we stop elephants lives from being taken. Currently there are an estimated 400,000 African Elephants left, and conservationists are predicting if we continue at 30,000 plus being killed every year then the species will be extinct in another ten years.

A group of very dedicated and passionate local citizens have joined together to create the San Francisco Elephant March. These people have worked day in and day out, campaigning, writing letters, signing petitions, educating, posting flyers, tabling, and some right here at the zoo! I would like to invite you to join us at the March For Elephants in San Francisco on October 4th at 11am. We will be gathering in Portsmouth Square, marching a peaceful protest, and ending in Union Square to listen to keynote speakers Patrick Freeman, Elephant Field Biologist, Patricia Simms, creator of World Elephant Day, and our neighbor and friend Mr. Ed Stewart, co-founder of Performing Animal Welfare Society. Please visit www.marchforelephantsSF.org for more detailed information. You can register for the march, purchase a t-shirt, and check out the map of the march. Please, I encourage everyone to attend this special event and spread the word about what’s going on with elephants.

Please Join us for the March in San Francisco!
