German-born forester Wilhelm Schlich (1840-1925) helped establish forestry as a scientific discipline in Great Britain. He emphasized sustainable forestry practices and the importance of preserving the productive power of the soil as a silvicultural objective.

On 9 March 2020, New York University announced that it was taking classes remote, and less than two weeks later the entire campus, including our beloved Bobst Library, shut down. While I was relieved that the university was taking the pandemic seriously and acting quickly to flatten the curve, the shut-down posed serious challenges not just to teaching but to research for both me and my students.

Thoreau the writer.  Thoreau the philosopher.  Thoreau the naturalist.  Thoreau the citizen.

The myriad of Henry David Thoreau’s titles demonstrates the fusion of interests that propelled his path toward becoming one of the key naturalist figures in history. Classic works like Walden and Civil Disobedience brought Thoreau literary renown as he proclaimed the philosophies of Transcendentalism and environmentalism. As a naturalist, his records of field specimens amassed in journals both while living at Walden Pond and long after. Though praised for his place in the American literary canon, he also made significant contributions to the scientific community. His field notes and data are now helping scientists learn more about species’ resilience, the effects of climate change, and the historical landscape of New England.

BHL has deployed a new taxonomic name finding tool to improve the speed and accuracy of identifying names throughout its 58+ million pages.

BHL is now usingGlobal Names Architecture’s (GNA) gnfinder tool to locate taxonomic names in the BHL corpus. Prior to this deployment, BHL’s name finding services were based on an index of scientific names created by GNA developers six years ago by parsing every page in BHL one by one. This took 45 days to accomplish, and the cost of repeating this process made updating or improving the index infeasible.

The gnfinder tool uses fast, scalable programming languages to significantly reduce computational time. Using Open Source applications in Go and Scala, the tool detects candidate scientific names and compares them to millions of scientific name-strings aggregated by GNA for verification. The new process decreases the time needed for name detection and name verification from 35 days to 5 hours and from 7 days to 12 hours, respectively. As a result, the entire BHL corpus can now be indexed in less than a day, compared to the 45 days needed for the previous index. Additionally, by significantly reducing computational time, implementing iterative improvements to the index is now achievable.

Considered the father of American landscape architecture, Frederick Law Olmsted co-designed many of the most well-known urban parks and landscapes in the United States in partnership with Calvert Vaux (Wikipedia). As Adam Gopnik wrote in The New Yorker, “Was there a patch of grass in nineteenth-century America that he didn’t design? Stanford, Prospect Park, and the Biltmore Estate, in North Carolina; the space around the United States Capitol and preservation plans for Niagara Falls and Yosemite.” In addition to his impressive accomplishments in landscape architecture, including seventeen large urban parks across the United States — most notably Central Park — he was also a journalist, abolitionist, gentleman farmer, and conservationist

That we live in a changing world should come as no surprise, yet how we measure that change can greatly impact our ability to respond to it. I am a scientist who works in the field of historical ecology — that is the use of non-traditional records to try and understand what ecosystems looked like in the past. My students Kate Henderson and Megan Hazlett and I are based out of the State University of New York College of Environmental Science and Forestry, where we look at how the state’s waters and shores have changed in order to better craft conservation goals. While we work on a variety of ecosystems, they are united by our need to understand where we come from in order to help direct where we are going.

Zoological knowledge typically comes from one of two primary sources: the living and the dead — observations of animals going about their business in their habitats; and the study of preserved specimens. We rarely get the whole picture of an animal’s natural history without both and each feed into how species are portrayed to those that have never seen them.
