After yesterday‘s late night, we were all slow to rise this morning. Which turned out to be okay, because at around 5:30 a.m. the crew decided to move to our next site; the movement of the ship was all the incentive we needed to sleep in.
When the ship stopped we got up for breakfast. Today’s first site is–like yesterday afternoon’s site–on Isla Gordon. From the map this site appears to have a glacier-fed stream that enters the sea near the end of a small sound, and this is indeed what we have found. But what we couldn’t see from the map is that the glacier is over the rise of a tall, steep slope, and after yesterday’s exhaustion, there wasn’t much enthusiasm for such a climb. So most of us chose to collect specimens on a relatively flat Magellanic tundra.

As the sky slowly darkened last night, we passed site after site that we all thought looked like great collecting localities. Today we begin finding out.
Isla Hoste
For our first collecting site, we have headed as far east as we will go on this leg of the trip. We are anchored in one of the innumerable, unnamed sounds that dot this area, on the north-central coast of Isla Hoste. Between Isla Hoste and Isla Gordon lies the Beagle Channel (named for Charles Darwin’s ship, the HMS Beagle), and we are planning to bounce back and forth across the southwest arm of the Channel.

I first stepped out onto the deck of our ship around 5 a.m. today. The sun wasn’t quite up and the mountainous islands were dark shapes against a gray, cloud-choked sky. I love early mornings alone with nature. Unfortunately I was dressed only in my sleeping clothes, so the light rain and cold quickly drove me back to my warm bunk.

We have a different ship this year, the Don José Miguel. It is relatively new and belongs to the same owner as our ship last year, the Don José Pelegrín. It is about a meter wider than the Pelegrín, making it seem much more spacious. On the Pelegrín the bunks were narrower and lower; the roomier bunks on the Miguel allow me to turn over without bumping into the bunk above me. But although the bunk room has more space, there is no place to put luggage except under the lower bunks, an inconvenient process which requires the removing of mattresses and the slats. As a consequence, most of our luggage is piled in the middle of the room, providing an obstacle course, especially in the middle of the night.
We have a large group this year, with eleven scientists and five crew. Out of the ten flying into Punta Arenas, only four made it on time. I arrived eight hours late due to mechanical problems in Atlanta causing me to miss my connection in Santiago. From Santiago I was scheduled to fly to Punta Arenas, on Sky, but when I arrived late, they told me that there was nothing they could do that day and that they had no responsibility to do so. So, I went to the larger airline, Lan, and was able to purchase a new ticket for later that same day; almost surely cheaper than a hotel and dinner in Santiago! When I arrived in Punta Arenas at around midnight, I found an empty airport completely devoid of taxis.
Our Chilean collaborator Juan Larraín, also had a Sky flight to Punta Arenas that was delayed–he was stranded at his layover in Puerto Montt and arrived four hours late. This is not an airline I intend to use again! Matt von Konrat, of the Field Museum in Chicago, also found himself delayed and had to spend the night in Dallas/Fort Worth. He arrived about eight hours late, finally landing in Punta Arenas around 3 a.m. After my late-night, taxi-less arrival, I knew Matt would have the same problem. Seeing as he speaks very little Spanish, Juan and I arranged for a taxi to pick us up at our hotel at 2:15 a.m., take us to the airport, wait, and bring us all back to the hotel. When Matt arrived in the baggage claim area, he looked very tired and weary, but his facial expression changed immediately to one of relief when he spotted us waiting for him.

Returning for a second expedition is Blanka Shaw from Duke University, as well as Matt (who has made a really great project website), Juan, and our facilitator/scientist, Ernesto Davis. I don’t think I can count how many trips Ernesto made to the airport, especially with all the missed and canceled flights. He is our hero.
The turn of the year from 2011 to 2012 was an exciting time for the scientists who work, teach, and research at The New York Botanical Garden.
No longer necessary: The describing of plants in Latin, followed by a translation in English.
In December, scientists at the Botanical Garden, the American Museum of Natural History (AMNH), New York University, and Cold Spring Harbor Laboratoryannounced that they had created the largest genome-based tree of life for seed plants to date. In January, James S. Miller, Ph.D., Dean and Vice President for Science at the Garden, explained important changes in the requirements for the naming of newly discovered plants beginning in 2012. Earlier in 2011, Dr. Miller had been the lead author on an article in the online journal PhytoKeys summarizing the changes. To say that these scientific advancements are huge is a gross understatement, but how to understand them?
Let’s use plain English, which is exactly what the new plant-naming requirements do. As outlined in an op-ed published in the New York Times on January 22, Dr. Miller, who took part in the International Botanical Congress in Melbourne, Australia, where the changes were approved, explains that plants will still be named in Latin, but that they will no longer have to be described in Latin. This laborious process–which has been on the botanical books since 1908–is only the first hurdle each botanist must clear before he may name a new plant species. The next step, the publishing of this description in a printed, paper-based journal, has also been done away with by the International Code of Botanical Nomenclature in an effort to speed the naming of plants. Why the hurry? As Dr. Miller says, “as many as one-third of all plant species (may be) at risk of extinction in the next 50 years.” One way to save a plant is to name a plant. From there, scientists–freed from the strictures of Latin–may further investigate the plant and all of its potentialities.
Our last attempt at hosting this “inside look” at The New York Botanical Garden‘s Science campus was rained out by a certain tropical storm (we’re looking at you Irene), so we’re trying again. And this time we’re making it even bigger and better than before!
The Science Open House weekend will be held in conjunction with the second Thain Family Forest Dedication festival weekend, which means there will be a ton of fun activities for the whole family! Start inside with a look at the beautiful Pfizer Plant Research Laboratory, then explore the fascinating William and Lynda Steere Herbarium, and finally, listen to Garden scientists talk about their forest-based research. Then head outside and enjoy the beauties of fall in the Garden’s historic, 50-acre Thain Family Forest: take an expert-led nature walk, canoe down the Bronx River and learn about its wildlife, climb a tree with an arborist, and so much more. The Garden is never the same two days in a row, so come spend a day in one of the world’s greatest urban gardens, The New York Botanical Garden!

Global warming has become one of the planet’s deadliest threats. Since the Industrial Revolution, carbon dioxide concentrations have risen from 280 ppm to nearly 390 ppm, with the potential to reach 550 ppm by 2050 if carbon emissions from fossil fuel combustion are not controlled. The earth has experienced major warming three times; but the Cretaceous warming period took place over millions of years and the Paleocene/Eocene warming happened over thousands of years. In contrast, today’s temperature changes are happening over decades. As a result, many species, perhaps even humans, may not be able to adapt to such rapid and high increases in temperature. One concern that is generally unknown to the public is that photosynthesis, the source of energy for nearly all organisms on the planet, shuts down at around 104° F. Mankind’s extreme disruption of the carbon cycle is causing and will continue to cause serious consequences for life on earth.
Carbon dioxide levels contribute to global warming through the greenhouse effect. Greenhouse gases trap radiation from the sun in the atmosphere, which causes global temperatures to rise because the radiation is not reflected back out of the atmosphere. The reason for today’s increased atmospheric carbon levels can be attributed to the combustion of fuels used for the production of electricity and in transportation, both of which are essential to modern societies; as well as to cutting and burning forests throughout the world. Since there is no precedent for the rapidity of current temperature increases, it is impossible for humans to predict which areas of the world will be affected and at what magnitude. The unpredictability of global warming makes it an especially serious environmental problem.
Rain forests as well as other vegetation types play an important role in reducing the levels of carbon dioxide in the atmosphere. Annually, plants in tropical rain forests around the world take in millions of tons of carbon dioxide and release millions of tons of oxygen through photosynthesis, and this balances the respiration of microbes, plants, and animals, which take in oxygen and expel carbon dioxide. As seen in the accompanying cartoon, plants take in carbon dioxide and water and use the energy of the sun to create carbohydrates that are, in turn, oxidized to produce the energy needed for plants to sustain themselves. The carbohydrates are also the building blocks plants use to make leaves, stems, flowers, and fruits. Oxygen, the byproduct of respiration, is used by organisms to break down ingested carbohydrates to produce the energy needed for them to grow and reproduce. Mankind’s extreme disruption of the carbon cycle is and will continue to have serious consequences for life on earth.
Briefings from the Field, a short lecture series featuring updates from the fieldwork of various Garden scientists, is open to the public Saturday at 2 p.m. in the Arthur and Janet Ross Lecture Hall

James Miller and Hannah Stevens of The New York Botanical Garden talking with director of the University of Puerto Rico's Botanical Garden, Rafael Davila.
The greatest challenge to protecting the world’s plant diversity is that while perhaps as many as 100,000 species of plants face some risk of extinction in the next few decades, in most parts of the world, we simply don’t know which species are the most threatened. Little progress has been made toward identifying the list of globally threatened plant species (which is target 2 of the United Nations Global Strategy for Plant Conservation), so NYBG scientists have developed a streamlined method to survey plant species one at a time, to determine which are “At Risk.”
The rapid review of Puerto Rico’s plant species demonstrates that 461 of them, or 23%, are at possible risk of extinction in the near future. This figure is consistent with analyses from other parts of the world, where it is frequent that about one quarter of species are threatened. Some of these threatened plant species are so rare that they have not been seen for decades and are possibly extinct, others are known from countable numbers of individuals, some less than 25, and thankfully the situation for others is not as dire, though still serious. Having this list will help guide future conservation efforts to the species that most desperately need our attention to ensure their future survival. Some of the participants from the Puerto Rican institutions plan to propagate the most rare species as a prelude to efforts to re-establish viable populations in the wild. The NYBG is extending these efforts and is aiming to complete a review of the entire West Indies in the next year.
