Finding Life in Dead Plants: Exploring Herbaria Through BHL

Read the full blog post

Visit any major botanical research institute today and you’ll find a herbarium, or collection of preserved plant specimens. These specimens are used to identify plants, to track where and when particular plants grow, and to help understand how plants are influenced by climate change and other environmental factors.

Formal herbaria have been around for about five hundred years. The first recorded herbarium was created by Italian physician and botanist Luca Ghini in the early 1500s. Called a Hortus Siccus, or “dry garden”, the herbarium was populated by drying plants under pressure between pieces of paper and then mounting the specimens for study. Today, herbaria are integral to botanical research.

Dr. Maura Flannery, Professor Emerita of Biology at St. John’s University in New York and a Research Associate in the A.C. Moore Herbarium at the University of South Carolina – Columbia, studies the complex history of herbaria, their many uses, their digital future, and relationships between herbaria and botanical art. While she has been studying biology and its links to art over most of her career, Flannery’s interest in herbaria emerged about ten years ago.

Smithsonian Libraries, BHL, and My Research on South Asian Mammals

Read the full blog post

I’m a Deep Time – Peter Buck Fellow in the Department of Paleobiology at the Smithsonian’s National Museum of Natural History where I study the ecology and evolution of prehistoric vertebrates, especially fossil mammals from the Indian subcontinent. The Indian subcontinent has one of the richest mammalian fossil records anywhere in the world. The Siwalik Hills and surrounding regions in Northwest India and Pakistan have a fossil record ranging from about 23 million years ago to about half a million years ago, making this region an ideal place to study how mammalian communities have changed through time.

Fossil mammals in India were first discovered by British explorers and naturalists in the 1830s and 40s. Hugh Falconer, Proby Cautley, W.E. Baker, and H.M. Durand discovered one of the largest deposits of fossil mammals from the Pliocene and Pleistocene (3.6 million years to 0.6 million years) in the region between the rivers Yamuna and Sutlej. These fossils eventually made their way back to the Natural History Museum in London and form one of the most important fossil collections in the world. These collections form the basis of my research on the reassessment of the taxonomy of fossil mammals from India, the biogeography of South Asian mammals, and paleocommunity change.

Building the Smithsonian’s Dinosaurs with Materials from the Smithsonian Libraries and BHL

Read the full blog post

My name is Michelle Pinsdorf, and I am a paleontologist and preparator of fossil vertebrates in the Smithsonian National Natural History Museum’s Department of Paleobiology. Preparators’ work can cover a wide variety of duties, from fieldwork to discovering new fossil specimens, to freeing those specimens from their surrounding host rock in our laboratories, to safely housing specimens for research collections, and helping to build exhibits for specimens going out on display. We call it “grave to cradle” work.

Most of the time you’ll find a fossil preparator leaning over a lab bench with a fine tool in hand, peering through a microscope and exposing the details of a fossil that helps researchers identify and publish about it. But for the past five years, my lab colleagues and I have been working on the renovation of the Natural History Museum’s fossil exhibits. This has involved the dismantling of many previously exhibited fossil mounts to allow for the conservation of the fossils and remounting them in new poses and settings. With the significant scientific value of these fossils, a lot of research and planning happens before each individual specimen is worked on.

Exploring Prehistoric Sloths: From Thomas Jefferson to Sloth Poop

Read the full blog post

I study sloths, and as popular as they have become on the internet, the thing most people do not realize is that we are living in a world majorly deprived of most types of sloth. Today there are only two types of sloths: two-fingered (genus Choloepus) and three-fingered (genus Bradypus). (You may have heard them referred to a two-toed and three-toed, but they both have three digits on their hind limb, so the difference is on the forelimb, in other words, their hand, hence: fingers.) There are only a few species of each kind of sloth and they all live in the trees of tropical rainforests in Central and South America.

But back in prehistoric times, there were many types of sloths: more than 80 genera across five different families. They lived as far north as the Yukon Territory and Alaska, as far south as Patagonia, and stretched from coast to coast in the United States and even colonized islands throughout the Caribbean. The smallest of these fossil sloths were still bigger than any sloth alive today, and the biggest extinct sloths were the size of modern elephants (but could probably walk around on two legs like an awkward bear). All this means there is a lot to learn about the sloths that are no longer with us.

Flower Flies and BHL: Empowering Taxonomic Research on Important Pollinators

Read the full blog post

The family Syrphidae, commonly called hover flies or flower flies, include some 6,000 living species. As “one of the most abundant groups of flower visiting insects”, with adults of most species feeding almost exclusively on pollen and nectar or honeydew, these flies are among the most important pollinators, both for wild plants and numerous crops.

The multi-volume Diptères exotiques nouveaux ou peu connus (1838-[43]) by Justin Macquart contains the first descriptions of numerous Diptera species, including many members of the Syrphidae. Systema Dipterorum, the biosystematic database of world Diptera, attributes 430 Syrphidae names to Macquart.

“Macquart wrote so many early Syrphidae genus and species descriptions that it’s almost impossible to write a syrphid taxonomic paper without referencing this title at some point,” explains Dr. Andrew D. Young.

Young is a University of California, Davis postdoc, working out of the California Department of Food and Agriculture Plant Pest Diagnostics Center, where he specializes in Diptera taxonomy and phylogenetics. Although he studies Tephritidae (fruit flies) in his current position, most of Young’s entomological training has been focused on Syrphidae. While Macquart’s monographic series is an essential resource for this group, it’s not easy to come by.

“Each volume is several hundred pages, and was published in the mid 1800s, so hardcopies are not particularly easy to get ahold of,” explains Young. “Most of the time when you do find a hardcopy, it’s one that’s been photocopied so many times it’s barely legible.”

Fortunately, Diptères exotiques nouveaux ou peu connus is freely available on the Biodiversity Heritage Library (BHL).

Getting Fishy with BHL: Empowering Discoveries and Connections Around Museum Collections

Read the full blog post

Twitter is a popular communication channel amongst the scientific community. Scientists use the platform to communicate with colleagues and share their research findings with both other scientists and the public.

Twitter may also be a valuable source of data for researchers. For example, ecologists from the University of Gloucestershire found that “Twitter-mined” data is useful for phenological studies, such as winged-ant emergence or the appearance of house spiders in the fall.

Twitter conversations can also spark unexpected discoveries. For example, a recent @BioDivLibrary Twitter conversation helped uncover a connection between the scientific literature and a museum’s collections.

Between Nature and Society: Empowering Research on the History of Science

Read the full blog post

Charles Darwin’s Library is a digital edition and virtual reconstruction of the surviving books owned by Charles Darwin. Produced as a collaboration between BHL, Cambridge University Library, the Library & Archives of the Natural History Museum in London, and the Darwin Manuscripts Project, the collection draws on original copies and surrogates from other libraries and includes over 500 of the 1,480 books in Darwin’s library. Notably, these books are complemented with fully-indexed transcriptions of Darwin’s annotations.

Charles Darwin’s Library is particularly meaningful to Dr. B. Ricardo Brown, Professor of Social Science and Cultural Studies at the Pratt Institute. Brown has devoted years of research to Darwin and the impact of his evolutionary theories on debates around monogenetic vs. polygenetic human origins. Brown’s 2010 book, Until Darwin: Science, Human Variety and the Origin of Race, explores the complex web of factors that influenced these debates from the 17th-19th centuries and the impact of the publication of On the Origin of Species on this scientific discourse.

Brown spent nearly 10 years researching this book. Today, BHL’s open access collections offer researchers considerable time-savings.

“I am sure that if I had the kind of access to texts that BHL now provides researchers, I could have reduced the research time for Until Darwin in half,” muses Brown.
