Nobody likes moving. The packing, taping, lifting, shipping… it can be major hassle. But nobody’s experience compares to what’s going on at the California Academy of Sciences. They’re moving to their new 400,000 square-foot building in Golden Gate Park after three years in downtown San Francisco. But they’ve got a lot more to move than most people. Try 38,000 live animals and 20 million scientific specimens.

From fossils and gemstones to bird eggs and a stuffed Kodiak bear, it takes a lot of creativity to pack their collection. Everything seems to have special requirements. Their fish collection is made up of 200,000 jars - all filled with alcohol. And since it’s a flammable liquid, they’ll need a licensed hazmat driver to take it across town.

The live animals take extra care, of course. In this story, we followed the move of three black tip reef sharks. They hadn’t been fed in a few days (so they wouldn’t make any, um, deposits in their holding tank) and they weren’t easy for the staff to catch, but they made it safely to their new exhibit. Even the largest of the three, F3 as she’s known, made it ok, despite being a little groggy at first from too much oxygen.

As curator Bart Shepherd put it, their new Philippine Coral Reef Exhibit is a giant science experiment. The water for the 200,000 gallon tank comes straight from the Pacific Ocean through a four mile pipe. But most impressively, the Academy has been growing coral just for the exhibit. Just managing the water chemistry alone has been a major project, but now several dozen colonies of coral are happily planted in their new home.

Make sure to check out the audio slide show for this story to see how the new building is shaping up. And check out a few of the posts from QUEST science blogger Cat Aboudara, who is an Academy staff member, for more details on what it takes (here, here and here).

A “penguin suit” doesn’t just refer to a tuxedo anymore.

Why does Pierre, the Academy’s 25-year-old penguin
need a wetsuit?Thanks to an innovative treatment at the California Academy of Sciences. Pierre, the Academy’s 25-year-old penguin was recently fitted with a wetsuit! Pierre’s feathers were thinning and not growing back. Because penguins rely on their feathers for warmth, Pierre was often shivering and uncomfortable without the protection of his feathers. When medical tests concluded there was no medical reason for the feather loss and more conventional treatments proved unsuccessful, senior aquatic biologist & penguin handler, Pam Schaller came up with a more creative approach to keep Pierre warm.

Pam was very familiar with the warmth of wetsuits. She then mused why couldn’t a wetsuit be designed for a penguin? She approached Academy veterinarian, Freeland Dunker with her left field idea. At first, he was dubious but after talking with Pam, he agreed it was worth a try as long as the wetsuit was fitted to insure it did more good than harm. In other words, as long as the wetsuit was fitted not to impede movement or cause rashes, it was worth a shot. Pam knew the best person to design a custom wetsuit would be Celeste Argel, the Early Childhood Specialist at the Academy, who is an excellent and creative seamstress. Celeste was asked to collaborate with Pam to develop and fit a wetsuit just Pierre’s size.

But how do you go about designing a penguin wetsuit? The answer seems to be trial and error. Celeste sat down with me and went over the details about the unusual experience. The process from idea to creation required a great deal of patience and re-fitting.

Celeste, Pam and Pierre met several times in order to customize dimensions. The first fitting consisted of Pam restraining Pierre in order for Celeste to take measurements. From the start, Celeste marveled at the strength of Pierre. “From far away,” she commented, “penguins just look so cute and cuddly but being up close gave me an appreciation for just how strong penguins really are.” With measurements in hand, Celeste drafted up a pattern for the wetsuit and created the first prototype from white cotton bed linens.

On the second fitting, Celeste was faced with a new challenge - getting Pierre’s flippers through the armhole. Pam wanted to keep the armholes as small as possible to maximize warmth. In doing so, Pierre’s flippers had to be bent at the joint and folded in upon themselves in order to thread them though the armholes. While Pam again restrained Pierre, Celeste applied pressure at the joint to fold his wings. “It was amazing and scary to fold up Pierre’s flipper. I wanted to make sure I wasn’t hurting him but to fold his flipper required a bit of pressure at the joint,” Celeste related. With the prototype on, Celeste was able to use a marker and note where the suit had to be taken in or taken out to make Pierre more comfortable. And then again, it was back to the drawing board.

A few more fittings took place to streamline the suit and to ensure that Pierre’s flippers had full mobility. Then Velcro was added to the back of the suit. Pierre was let loose in the penguin enclosure to see how he moved. Both Celeste and Pam sat down to watch his movements and observed where the fabric was bunching. Pierre seemed to be adjusting to his suit quite well but the other penguins, new to a mostly white Pierre, started poking and prodding to investigate the newly adorned bird. Because of the interest from the other birds, the session in the suit only lasted a few minutes. Celeste changed the color of the prototype to a dark brown to see if the other penguins would respond differently and they did. They accepted Pierre with a dark physique. More sessions in the new prototype followed and when Pierre jumped into the water and swam around with the suit on, Celeste and Pam knew it was time for the neoprene fitting.

Celeste conducted research to see how neoprene would act differently than cotton. From her research, she concluded that the whole suit would have to be taken in at least an inch because of the give of the material. However, Celeste didn’t have a machine to sew neoprene effectively so Pam asked Oceanic Worldwide, who supplied wetsuits to the human staff at the Academy, to manufacture a neoprene suit. Pam delivered the working prototype and the patterns to Oceanic who agreed to donate their time and materials. “We were really excited to do it,” said Teo Tertel, company marketing specialist. “We heard most of these penguins only live to 20, and our little buddy there was already 25. Anything we could do to help them, we were all for it.”

When the suit from Worldwide was delivered, it still wasn’t quite ready. The neoprene suit fit differently than expected and had to be re-fitted all over again. However neoprene can be glued instead of sewn so it was a matter of trying the suit on Pierre, marking where it didn’t fit snugly and adjusting. “I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely streamlined,” Pam remarked on the final alterations. There were hiccups with a penguin being in a wetsuit for the first time and being curious about the Velcro and tabs. So nothing was left unaltered for Pierre’s comfort and mobility.

With all the alterations finally done, a final set of patterns was delivered to Oceanic Worldwide and they again donated their time to manufacture the final wetsuit for Pierre. All the hard work paid off for all involved when Pierre became warm again. It was a huge bonus when he also started to gain weight and his feathers began to grow back. The goal of designing the wetsuit for Pierre was to keep him comfortable and warm and the custom suit worked much better than expected. Having Pierre happy and healthy without the further need of the wetsuit was a perfect outcome for a very unusual treatment.

The camera has long been an invaluable tool of field researchers. For example, the initial identification of a new mammal species was initiated by a camera trap set up by Francesco Rovero of the Trento Museum of Natural Sciences in the Ndundulu Forest in Tanzania’s Udzungwa Mountains. Both Francesco Rovero and Galen Rathbun of the California Academy of Sciences followed this photographic proof toward the discovery of a new species of Giant Elephant Shrew - the grey-faced Sengi. Photographs allow researchers to view their surroundings in a more intimate way and extrapolate meaningful data. It can even lead to incredible discoveries.

The California Academy of Sciences is asking youth to get behind the camera to find discoveries in their backyard. On April 15, 2008, the Academy launched a photo contest for youth between the ages of 8 & 12 - “Through the Lens: California in your backyard”. Future photographers, researchers and scientists are right in our own backyard and the Academy is curious about what they are seeing in their surroundings. This contest will give youth a chance to have a researcher’s eye - to “get up close” and document what they observe.

The photographers with the “best eye” will have their work hung in a museum. The work of winning photographers will be exhibited as part of the Children’s Gallery at the Grand Re-opening of the California Academy of Sciences on September 27, 2008 and throughout the inaugural year. Winning photographers will also be awarded cash prizes.

It is up to the photographer how to convey the theme of this contest - “California in your backyard” and the Academy’s mission - to explore, explain and protect the natural world. All photographers entering the contest are encouraged to have lots of fun and be as creative as possible.

The deadline to submit photographs is May 26, 2008. Contest rules and submission instructions can be found at www.calacademy.org/contest. Aspiring and curious youth photographers are encouraged to submit work. It might be the catalyst to another great discovery!

A Baobab TreeIt is not only animals that can be become endangered but plants and trees as well. One of California Academy of Science’s research areas has been Madagascar. Coined as an “Island of Evolution,” Madagascar hosts a rich biodiversity of plant and animal life that is indigenous to the area and, unfortunately, highly threatened. Among the endangered in Madagascar is the Baobab Tree - Adansonia grandidieri.

Baobab is the common name of the genus Adansonia. The genus contains eight species of tree – six are native to Madagascar, while one species occurs in Mainland Africa and one in Australia. The Baobab tree is the national tree of Madagascar and is also known as the boaboa, bottle tree, the monkey bread tree, or the upside down tree: It looks as if someone took a tree out by the roots and turned it upside down. Throughout most of the year, its branches are bare, making them resemble a network of roots. All Baobab tree species occur in naturally dry areas and shed their leaves in the dry season to survive harsh drought conditions. Baobab trees can reach a height of 80 feet and a trunk diameter of 23- 36 feet. The trees store water inside the trunk during the dry season. During the rainy season, the trunk will increase or decrease in girth depending on rainfall amounts. It is difficult to determine how long these trees live, as their wood does not create growth rings, but current evidence points to a lifespan of up to 400 years.

The Adansonia grandidieri is the largest and grandest of the Baobab family. It has a massive cylindrical trunk covered with smooth, reddish-grey bark. When in bloom, the flat crowns of the trees bear bluish-green palm-like leaves and dark brown floral buds or spectacular flowers with white petals. It produces leaves from October to May and flowers from May to August. The flowers open around dusk and they all pollinate on the same night they flower. Nocturnal animals pollinate the trees by licking the nectar from the flowers and repeating this process from tree to tree. Scientists believe only lemurs are now capable of pollinating these trees. Before the colonization of Madagascar, other nocturnal animals and the elephant bird also were seed dispersers, but these species have long gone extinct.

Humans have not only affected the number of animals that can pollinate the tree, they have changed the tree’s environment and exploited its various parts. These trees historically prospered in dry, deciduous forest, especially near seasonal river or lakes. Today, they are mainly found in open, agricultural land because of the increased demand for farming. Many trees are scarred from pegs hammered into the bark by humans, who use them to climb up the trunk to collect seeds. The bark is stripped to make rope and the wood is carted away to use for thatch. Because of the changes made to their environment and the exploitation of their resources, there are few young baobab trees, which could seriously hinder species survival. Numerous organizations and researchers, like those at the Academy, along with the Malagasy government, have realized the importance of conserving the unique biodiversity of Madagascar and are working to protect this hotspot. One measure, which will help the Grandidier’s baobab, is the 2003 pledge from the President of Madagascar to triple the number of protected areas in the region. This will not only help restore an incredible area of biodiversity but also help the Malagasy people. Their livelihoods depend on the continued preservation of their watersheds and forests.

With the appearance of spring, I have been noticing new couples and flirtations come alive after being dormant in the gloomy days of winter. When out with my girlfriend and her new beau last night, it was all the more apparent as the third wheel! This is not the first time that during this time of year, I’ve noticed an increased flirtation and coupling among my friends and I do wonder if there is an evolutionary reason for the heightened activity.

The woman who could probably give me a definitive answer is evolutionary biologist and award winning science journalist, Olivia Judson. Her first book was entitled Dr. Tatiana’s Sex Advice to all Creation. It uses a playful literary tool to elucidate the evolutionary components of sex. The book sets up the chapters as advice columns. One such insect from the book complains:

“Dear Dr. Tatiana - My name’s Twiggy and I’m a stick insect. It’s with great embarrassment that I write to you while copulating, but my mate and I have been copulating for ten weeks already. I am bored out of my skull, but he shows no signs of flagging. He says it’s because he’s madly in love with me, but I think he’s just plain mad. How can I get him to quit? - Sick of Sex in India”.*

By anthropomorphizing animals and posing questions as a catalyst, Judson is able to fuel a fascinating outlet to dive into some of the racier sides of sex and really investigate the evolutionary reasons why they exist. No rock is unturned throughout the book. Frustrated birds, mammals, insects, reptiles, and bacteria write in and reveal quite startling behavior. The prologue of the book asserts that:

“Dr. Tatiana’s Sex Advice to all Creation is a unique guidebook to sex. It reveals, for example when necrophilia is acceptable, and who should commit bestiality with whom. It discloses the best time to have a sex change, how to have a virgin birth, and when to eat your lover. It also advises on more mundane matters - such as male pregnancy and the joys of a detachable penis.”**

Most information is retained when it is enjoyed. My friend first recommended this book a few years ago. He was required to read it in his college class Darwin and Darwinism. We laughed about the required reading list, but I have often given this book to friends who have no interest in science and they have all enjoyed it despite the fact that delving into evolutionary biology is often quite difficult. More so, I found out only recently, this book is also part of the reference material for our docent program at the museum. Every year, Animal Sex Tours are led by the docents throughout the museum. The tours sell out every time and a great deal of creative insight has stemmed from this book. If you, as a reader, are curious - find out more about the author and the book at http://www.drtatiana.com/index.shtml. It is definitely a great science read for the beginning of spring!

Diversity of thought has always been a cornerstone of science; however, diversity amongst scientists has often gone unnoticed. Martin Luther King’s birthday was just celebrated in remembrance of his leadership in the African American community. However, he is not the only pioneer who has brought about great and lasting change. Below are just two examples of the great scientists and innovators in the African American community who have graced the history of science for the betterment of mankind.

George Washington Carver: (1864-1943)
Agricultural Chemist and Innovator

On the epitaph on the grave of George Washington Carver it reads, “He could have added fortune to fame, but caring for neither, he found happiness and honor in being helpful to the world.”

Through his work as an agricultural chemist, Dr. George Washington Carver changed the agriculture of the South by discovering three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. From the peanut Dr. Carver created meal, instant and dry coffee, bleach, tar remover, wood filler, metal polish, paper, ink, shaving cream, rubbing oil, linoleum, synthetic rubber, and plastics. From the soybean he obtained flour, breakfast food, and milk. He also significantly boosted the agricultural economy by formulating the crop rotation method, which revolutionized agricultural practice. He educated the farmers to alternate the soil-depleting cotton crops with soil-enriching crops such as peanuts, peas, soybeans, sweet potato, and pecans. He did not profit from these discoveries but freely gave them for the benefit of mankind, and it was said he turned down a $100,000 salary in order to continue his agricultural work. Rising from slavery in Diamond, Missouri, Doctor Carver struggled to gain an education and used it to give back to the land. Dr. Carver died in 1943 and was buried next to Booker T. Washington at Tuskegee Institute where he worked as the Director of Agriculture. On July 17, 1960 the George Washington Carver National Monument was dedicated at Dr. Carver’s birth site. This was the first U.S. federal monument dedicated to an African-American.

Matthew Henson

Matthew Alexander Henson (1866-1955)
Arctic Explorer

“As I stood at the top of the world and thought of the hundreds of men who had lost their lives in the effort to reach it, I felt profoundly grateful that I, as the personal attendant of the commander, had the honor of representing my race in the historic achievement.”

Matthew Henson was the first man to reach the geographic North Pole with long time colleague and explorer Robert Peary. Henson was born of poor parents in Charles County, Maryland. His parents died at the age of twelve and he was then shipped off to be a cabin boy on a merchant ship. He educated himself on the sea and became a skilled navigator. Henson met Commander Robert Peary in 1888 and joined him on an expedition to Nicaragua. Peary was impressed with Henson’s seamanship and recruited him as a colleague. For years they made many trips together, including Arctic voyages in which Henson developed trading with the Eskimos by learning their language, building sleds and training dog teams. In 1909, Peary led his eighth attempt to reach the North Pole and selected Henson to be one of the team of six who would make the final run to the Pole. Peary became ill before reaching the summit and sent Henson ahead as a scout. Later, when measurements were taken, it was discovered that Henson, during his scouting had been the first mortal to walk on the top of the world. Although it was Peary who got most of the acclaim for the exploration, it was Henson who made the first historic steps. On November 28, 2000, the National Geographic Society recognized those steps and awarded the Hubbard Medal to Matthew A. Henson posthumously.

At 5pm on Sunday January 6, 2008, California Academy of Sciences closed its temporary location in order to start the move back to Golden Gate Park. On September 27, 2008 the Academy will open to the public once again in its new home in the Park. Many curious museum-goers have asked, why the long gap between closing and opening? 265 days is long time to move across town.

What is on the public floors of the museum is just the tip of the iceberg of the Academy’s collections. Over a span of more than 150 years, the Academy has built an invaluable collection that acts as a strong backbone for the museum. Twenty million research specimens and 38,000 live animals have to be carefully packed and transported. The Academy is undertaking the most massive move ever undertaken by a museum.

The Botany collection was the first to move out of Howard Street. It took only eleven and a half days to move two million specimens. For perspective, it took 61,300 cardboard inserts bundled with over 40 miles of twine to bundle the flora. Botany is only one of eight Academy research departments preparing to move.

The Academy’s packing list is as varied as its research. Ornithology and Mammalogy have to transport Monarch, the last Grizzly bear of California. Because of its size and girth, it will not be boxed. However, it will take several movers to transport it carefully. Monarch will be joined by 30,000 other mammal specimens, including study pelts, skulls, skeletons, and the world’s largest collection of marine mammal specimens.

It will be even more challenging to move the Academy’s live animals. 38,000 live animals will be moved, water included, back to the Park in tanks of varying sizes. One of the aquarium’s Australian Lungfish will be the oldest living animal to move. Over seventy years old, this fish has seen the Academy through many changes– a move to Howard Street, and now the move back to Golden Gate Park.

The Academy’s Galápagos collection will also be packed up. It features thousands of Geospizine Finches (the group studied by Darwin) and the world’s largest collection of reptiles from the Galápagos.

Cultural keepsakes will be preserved. Pre-Columbian Inca clothing, 12th Century Persian ceramics, fragile feather leis, full-sized Native Alaskan kayaks, 500 Japanese folk toys, and a renowned collection of eating utensils will also find their home in Golden Gate Park.

To give you a sense of the immensity of the project, 20 million specimens include the following:

• Over 200,000 fish specimens preserved in alcohol, including a rare coelacanth (thought to be extinct until discovered in the 1930s);
• 14.5 million insects and arachnids, including more than 874,789 flies, some 524,666 true bugs, nearly 3 million beetles, and more than 700,000 butterflies and moths;
• Nearly 100,000 bird specimens, including the now-extinct Guadalupe Storm Petrel and 10,600 sets of bird nests and eggs;
• More than a quarter of a million reptiles and amphibians from 166 countries.

The sheer volume of this move makes it a migration. Over 20 million specimens can not be moved in a day. It will take every one of those 265 days to move and prepare to share the wealth of the Academy once again with the public.
