APES & MONKEYS - Updates From the San Diego Zoo

"Orangutans Clyde and Cinta" by Tanya Howard, San Diego Zoo Blog 2/8/2013

Clyde is doing really great at the Rolling Hills Wildlife Adventure in Salina, Kansas (he moved there in May 2011, see post Changes for Orangutans).  Clyde and Rusa continue to get along well.  Both animal staff and animals alike love Clyde.  He is the only male with whom female Ruse has been paired that she likes!  But who wouldn’t like Clyde?  He is the sweetest male, and all the girls like him (well, except Indah, of course).  There is not any expectation of an offspring from them, though.  Rusa has some reproductive issues that would make getting pregnant very difficult.  A baby would be a happy surprise.  The keeper there was telling me that Clyde is funny about his browse; he is turning his nose up at the Midwest varieties of trees and leaves.

After a few setbacks, Cinta is with all of the orangutans at the St. Louis Zoo (he arrived there in October 2012).  Originally, the staff was planning on introducing Cinta to the mother and daughter there, hoping for a successful pairing with the older female.  Unfortunately, the females had a different idea!  While reevaluating the situation, the staff noticed that Cinta and Robbie, their 19-year-old male, seemed compatible.  They were separate from one another but were sharing food back and forth and hanging out near one another.  Staff never planned on introducing the two males, but they decided to try and then, later on, Robbie and Cinta could together be reintroduced to the girls.

This has proven to the best of solutions.  Cinta and Robbie are now best of friends!  They hang out together and share food.  Just last week, staff put all four together with a much-improved outcome.  Now, whenever there are any problems, Robbie steps in and defends Cinta (not that Cinta needs much help—he is much faster that the girls!  Keepers are very positive about the improvements they have seen and expect things to continue to get better.  We will keep our fingers crossed for a successful pairing!




"What Might Monkeys Be Up To?" by Chia Tan, San Diego Zoo Blog 2/12/2013

February 10 marks the beginning of a new year, the Year of the Snake, according to the Chinese lunar calendar.  I cannot help but reflect on what I have done in the past year and contemplate what I wish to accomplish in this new year.

Last year, my research project focused on an investigation of wild Guizhou snub-nosed monkeys in China using camera traps.  This work was conducted in Fanjingshan National Nature Reserve (FNNR) in collaboration with the reserve’s administration.  We set up a network of over 100 camera traps to monitor, in addition to the Guizhou snub-nosed monkey, many hard-to-see wildlife species in the reserve (see post Monkeys, Leopard Cats, and Bears, Oh My!,).  Some of our unexpected captures were images of Guizhou snub-nosed monkeys moving about in the middle of the night (see article in Primates).  Although these monkeys are considered daytime active species very much like humans, our camera-trap data provided unequivocal proof that they are routinely active after dark.  What might the monkeys be up to?

Guizhou snub-nosed monkeys’ nocturnal habit, we believe, is motivated by the need to acquire as much food as possible.  In other words, the monkeys are up at night because they are hungry.  To some people, this discovery may seem like a non-discovery, but many great scientific discoveries are inherently simple, and they often start out with a simple observation, like the apple that fell on Newton’s head.  But I digress, back to the monkeys.

An important outcome of our camera-trap study, besides showing the behavioral flexibility the monkeys have to cope with living in a highly seasonal environment, is the need for researchers to rethink methodological designs that minimize observer bias.  If we habitually observe diurnal primates during the daytime we, of course, have data that only show them being active during the hours we observe them.  Camera traps, therefore, are excellent devices to augment our data collection.  And, because of the amount of photographs we have, you can count on me spending much of my time this year uncovering more secrets about the animals in Fanjingshan.

An intrinsic part of what I do as a scientist is to assist students with their professional development.  Through mentorship of students, I help foster future colleagues and, in turn, expand my network of collaborators.  This past year several of my students completed their research thesis, attained a higher degree, received scholarships, and/or launched new projects.  James Dopp is a graduate of the University of Vermont who worked with me in Fanjingshan in 2010 through 2012.  He has been awarded a Fulbright Fellowship to further sharpen his research skills in primate conservation in China.

Kefeng Niu, a resident biologist of FNNR, continued to benefit from my coaching.  In August, he successfully delivered a paper in English at the International Primatological Society Congress.  The Congress also provided Kefeng a chance to meet other professionals, among them, Dr. Marco Gamba, my Italian colleague from the University of Torino.  I introduced Marco and his research on primate vocal communication to Kefeng.  We later invited Marco to join us in Fanjingshan to resume our wonderful discussion about snub-nosed monkey biology with China’s renowned primate expert, Yeqin Yang (see post Saving Monkeys Takes a Team).  And the rest, as they say, is history, because when Marco left Fanjingshan, he had already signed a five-year research agreement with the reserve administration and gained a prospective PhD student, Kefeng Niu.  Mama mia!

Recently, my mentorship pool of students included a junior from High Tech High International.  Her name is Cameron Ishee, and though only 16, she is well on her way to transforming how people perceive and treat animals.  Because of Cameron’s ability to speak Chinese (Mandarin), I asked her to help me create a series of bilingual video lessons for the children in the Little Green Guards program in Guizhou (see post March of the Little Green Guards).  Each episode stars Cameron as Yi Jie Jie (or Big Sister Yi) teaching an English alphabet letter and about half a dozen animal-related words associated with the featured letter.  To make learning memorable and fun, we segue from the classroom lessons into video segments of our Zoo and Safari Park animals.  In doing so, we are achieving several objectives: introducing a world-class animal collection to underprivileged children who would otherwise never have the opportunity to travel to San Diego, and enhancing the school curriculum by teaching these children a highly valued foreign language that only children living in the more affluent urban areas of China are learning.

Our pilot episode is almost complete.  Cameron and I will continue making more episodes this year.  Just a little spoiler alert here, snake will be featured in our upcoming episode:  “S is for Snake.”
