Board of Trustees Dear Friends, Chair of the Board Cynthia P. Heckscher The conclusion of our 200th year represents a new beginning for the Academy. In our Trustees third century, we will weave sustainability into our institutional fabric, working diligently Peter A. Austen to promote critical evaluation of some of the most crucial environmental issues of our John F. Bales III time. We have enlisted the expertise of Resonate (page 14), a strategic sustainability Helen Y. Bowman management firm that is enabling us to construct a plan to further integrate sustainability Byron T. Clark into our public programs, budget, and internal operations. We are exploring innovative Carl S. Cutler Abbie Dean ways to help our visitors and other members of the Philadelphia community to reduce Harvey I. Forman their environmental footprints. These initiatives are the perfect additions to our renowned John A. Fry programs in biodiversity and environmental research. George W. Gephart Jr. In this issue of Academy Frontiers you’ll notice a few changes. We hope these Mark L. Greenberg adjustments will bring you even closer to our work. A theme of this issue is Mongolia, Catherine T. Hunt where our scientists have been working for nearly 20 years to track biodiversity and David P.

Drawn to Dinosaurs: Hadrosaurus foulkii Art of Science Gallery Open through June 9, 2013 The Academy of Natural Sciences was the first in the world to create a mounted dinosaur skeleton for display, and to this day the Academy is known as “the dinosaur museum.” Drawn to Dinosaurs: Hadrosaurus foulkii is an intimate exhibit that reveals the science and art of visualizing a living animal based on fragmentary fossils. The centerpiece is a full cast of the plant-eating duck-billed dinosaur Hadrosaurus foulkii, discovered in 1858 in Haddonfield, N.J., by an Academy member and later reconstructed by the artist Benjamin Waterhouse Hawkins based on Academy research.

After a decade of sampling, the scientists have collected hundreds of thousands of specimens from more than 400 sites across Mongolia. The team has developed guides that help identify the nearly 1,500 species of aquatic insects; a third of these species are known in the country for the first time because of the fieldwork. Some species they discovered are new to science, including crane flies the scientists named in honor of Clyde and Tuya Goulden. “Our goal has been to understand the aquatic insect diversity of Mongolia—so Mongolians could use that data to make assessments of water quality in the future and protect their biodiversity,” Gelhaus says. In 2012, Academy Curatorial Assistant and butterfly expert Stephen C. Mason Jr. Jon Gelhaud/ANS Jon (more on page 7) joined Gelhaus in Mongolia.

Almost every July since, Gelhaus has led 15 to 20 scientists and students from the United States, Mongolia, and Europe on expeditions across the steppe to collect insects and assess their habitats. Aquatic insects comprise the majority of any stream’s biodiversity, Gelhaus explains. Their larvae play an important role as food for fish and other water-dwelling organisms, and the adults fly throughout the stream areas, becoming prey for birds and terrestrial insects. Examining the aquatic insect diversity at any given site helps scientists to measure water quality. They can reveal the impacts of climate change, development, or animal grazing by evaluating the balance between insect species tolerant of and sensitive to these changes.

Resonate: A Leader in Sustainability and Service Nancy Cleveland and Jen Anderson say they are starting to see the Academy as their Center City office— in a good way. The co-founders of Resonate, a strategic sustainability management firm, empower companies to endure into the future by helping them to understand and manage the ways in which their activities impact people and the planet. Cleveland and Anderson have been partnering with the Academy to develop its sustainability plan for more than a year. In selecting Resonate, the Academy’s goal was to integrate sustainability into its strategic operations and to fill gaps in public education and engagement on this critical issue. Merging Resonate’s expertise in sustainability planning with the Academy’s long-standing commitment to environmental stewardship has been more rewarding than either team imagined. “The Academy is a wonderful client because so many things that have come up are already being done,” Cleveland says. “The Academy can contribute enormous value to the process of understanding what’s happening on the planet with reference back to the long historical record that constitutes its Jen Anderson (left) and Nancy Cleveland M.A. Hartsock/ANS collections.

Students and Science

Last fall 1,200 middle school students came to the Academy for two exciting STEM (science, technology, engineering, and math) career days, made possible by a generous grant from Philadelphia- based chemical manufacturer FMC Corporation with additional support from Pfizer, Inc. About 15 FMC scientists demonstrated scientific activities up close and hands-on, all to inspire students to pursue careers in the field. The Academy provided interactive activities and teacher resources for bringing math and science into the classroom. Gary Horn
