ConservationInspired Merchandise: It’s All About Dollars and Sense By Corrin LaCombe
Brown Endowed Research Coordinator Conservation Education
I remember when I first read the article “Orangutans in Your Shopping Cart and Gorillas in Your Cellular Phone” by primatologist Lily Dietz. At first, I thought what on Earth is she talking about—there are no orangutans in my shopping cart or gorillas in my phone! But as I made my way through her article, I began to realize what Lily was saying. You see, palm oil (used in everything from food to cosmetics) and coltan (a metal found in our cell phones and other electric devices) are harvested from prime orangutan and gorilla habitat, respectively. Lily was showing us that our consumption choices matter.

Intrigued, I began acquiring additional information about how our dollars and decisions affect animals and ecosystems around the world. I dove headfirst into books, such as Jane Goodall’s Harvest for Hope, Colin Tudge’s Feeding People Is Easy, and Daniel Quinn’s Ishmael. And I quickly learned that with one choice, one meal, one conscious purchase at a time, we can contribute to conservation and improve our planet. I brought this focus to my work at the Institute for Conservation Research and am very excited that San Diego Zoo Global is doing quite a lot on both the consumption and production side of the market.
I quickly learned that with one choice, one meal, one conscious purchase at a time, we can contribute to conservation and improve our planet. To address consumption, we recently signed on as an official member of the Roundtable on Sustainable Palm Oil (RSPO). The group represents an international network of producers, distributors, and conservationists dedicated to transforming the market to make sustainable palm oil the norm, which would reduce impact on animals like orangutans in Borneo as well as sun bears in Borneo and other parts of Asia. As a new member of this network, we are working to ensure that if and when we use products made with palm oil, our dollars will only support environmentally responsible palm oil producers and distributors. No more orangutans in our shopping carts! To address production, we collaborate with local artisans in regions where we have active conservation projects. Our intention is to bring beautiful handicrafts and other unique

products from our field sites to expanded markets, including San Diego Zoo and Safari Park gift shops. We recognize that conserving an ecosystem and its species can’t be accomplished if poverty prevails in the area. To create successful and sustainable conservation projects, we need a solid strategy that makes both environmental and economic sense for local communities. Through training workshops and creative thinking, we collaborate with community members to find markets for their products as well as ensure a sustainable local ecosystem. Through this process, alternative income sources are made available, providing artists and other community members with greater opportunities to earn a livelihood through craftsmanship and symbolic representation of plants and animals found in their own backyards. Our first round of “conservation-inspired� products are currently being handmade by artisans (pictured) in the Lambayeque region of northern Peru, an area where our scientists have been working to understand and protect a population of Andean bears for the past seven years. As a collaboration with the Spectacled Bear Conservation Society, this initiative has created more than 200 environmentally friendly, sustainable job opportunities as well as adorable felt animals for sale. We encourage you to harness your purchasing power by buying one of these unique pieces or any other product that helps support and conserve nature. Through our careful consumerism, we can all help to save species: it just takes one conscious purchase at a time.

hen an egg doesn’t hatch, what went wrong? Captive breeding of critically endangered birds, where every egg counts, can be tricky. Here in the Reproductive Physiology Division, we are working hard to assist avian conservation programs by developing new fertility testing methods. One new method I am helping to develop is in ovo sperm detection. Barren eggs are not uncommon, and every year we receive hundreds of potentially infertile eggs from the Zoo, Safari Park, and off-site breeding facilities. Numerous undeveloped eggs from a given breeding pair may indicate their inability to produce offspring. This can occur for a variety of reasons, including sterility, genetic incompatibility, or the absence of mating. Although discovering the absence of sperm within an egg does not provide all the answers, it is a key piece of the puzzle that can help narrow down the potential cause of a reproductive problem. When eggs arrive in our lab, the yolk membranes are removed and stained for sperm. There is nothing more exciting than locating sperm under the microscope! Not only does this indicate that the male is producing viable motile sperm, but their presence also provides hope that offspring from that pair may be possible in the future. Most of the eggs received by our lab are partially incubated, and we know that sperm slowly degrade during the incubation process. Determining a sperm degradation timeline is especially helpful for kiwi conservation. This species has an unusually long incubation period of

CONSERVATION UPDATE
almost three months, so its eggs spend a significant amount of time incubating before they are declared potentially infertile and sent our way for sperm detection. Although one of the female kiwis at the Zoo is producing eggs, none of them have hatched. But because we have been able to identify sperm in a few of their eggs, now we know that they are actively breeding! In 2012, I also analyzed eggs from a San Clemente loggerhead shrike subspecies on that island, where we have managed a breeding facility funded by the U.S. Navy since the early 1990s. One of the captive pairs had laid a clutch and then abandoned it. The male was one of the program’s oldest birds, and Conservation Program Manager Dr. Susan Farabaugh suspected that he might be ready for retirement. She brought several fresh eggs to the lab from the fruitless shrike pair, as well as a presumed fertile egg from a prolific pair that had accidentally broken during incubation. Upon inspection, I located a single sperm on the membranes from the unsuccessful pair, while the cracked egg contained numerous glowing sperm. This revealed the older male’s reproductive problem, and Susan immediately paired the female with a younger male. Her decision paid off, resulting in three additional chicks! While sperm detection is not the only method for assessing breeding potential, it is an important management approach for our avian conservation programs. It is yet another tool for managers to more confidently assess breeding pairs, allowing us to hatch the greatest number of chicks before the end of the breeding season. For birds on the verge of extinction, every chick brings the species one step closer to recovery.
