Hall of Human Origins Tour

On Sunday, January 29, Anna Ragni, a Ph.D. student in anthropology, led 26 participants on a tour of the Hall of Human Origins at the American Museum of Natural History. Ragni took us on a journey through the course of human evolution. She discussed morphological changes, particularly in bone and tooth structure, that occurred during this time and explained the significance of recent anthropological discoveries. 

Anna Ragni is a Ph.D. Candidate at the Richard Gilder Graduate School of the American Museum of Natural History. As a master’s student at the University of Arkansas, she worked on the evolution of diet in Brazilian monkeys and South African fossil hominins. For her Ph.D., Ragni is studying how development plays a role in the evolution of bipedal locomotion using CT scanning of modern primates.

Notes from the Field Presentations

On Sunday, December 4th, The Metropolitan Society of Natural Historians hosted Notes from the Field Presentations at the Richard Gilder Graduate School of the American Museum of Natural History (AMNH). During this event, three researchers from the AMNH, Columbia University and the City University of New York discussed their recent field expeditions across the world to look for fossils, deep sea creatures and leeches. 

Abagael West is a paleontologist who specializes in the study of fossil mammals. She received her B.A. in Zoology from the University of Cambridge in 2010, and is currently a Ph.D. candidate at Columbia University, in the collaborative program with the Richard Gilder Graduate School at the AMNH. After defending her Ph.D. in late December, she is moving to the Carnegie Museum of Natural History as a Rea Postdoctoral Fellow. Her research is on several aspects of the evolution and relationships of the Notoungulata, an extinct order of hoofed mammals from South America. She is particularly interested in using ancient DNA and protein sequences to test and augment traditional paleontological hypotheses and datasets. West discussed her field expedition to Antarctica to look for fossils. To learn about this Antarctica expedition, visit the project's website or twitter account. Various new articles were also published about the expedition in Arctic Sun, Forbes, and the Guardian. A youtube video about the project is also available.

Michael Tessler is a fourth year Ph.D. Candidate at the AMNH’s Richard Gilder Graduate School. He is generally interested in biodiversity and has conducted studies on leeches, mosses, and bacteria. The focus of these studies has included taxonomy, systematics, ecology, and conservation. He has helped pioneer new methods for comparisons of sites for conservation purposes and CT scanning of soft-bodied invertebrates to describe new species of leeches. Tessler presented his experiences traveling across Asia, Europe, North America, South America and Central America to look for leeches in both terrestrial and aquatic habitats and also discussed some cultural experiences from his travels. If you would like to learn more about Tessler and his research, please visit his website or the website of the Leech Lab at the AMNH.

Maggot Art With Dr. Jennifer Rosati

It was a chilly autumnal day on October 29th when members of the Society gathered at John Jay College's campus. Led by Dr. Jennifer Rosati, a professor of forensic entomology at John Jay, and her two research assistants, the attendees' charge was two-fold: to explore the lifecycle of the blow fly, which plays an important part in time-of-death determinations, and to utilize third-instar larvae to create unique works of art. Dr. Rosati explained how blow flies are typically the first insects to interact with a body immediately after life is terminated. Within minutes, adult flies can lay up 350 eggs on the dead tissue. It is here that the maggots (larvae) remain until they have amassed enough energy to engage in their "wandering" stage. Taking advantage of the maggots' search for a suitable place to pupate, Society members dipped the maggots in non-toxic acrylic paint and watched them as they took off in all directions on canvas. The maggots had no particular direction to travel, and as such, they simply wandered all around and eventually off the edges of the paper. Everyone likely spent as much time chasing maggots as the maggots spent creating colorful trails. When the maggots stopped wandering, they were all collected so that they may continue on to become pupae. Dr. Rosati also provided a brief tour of the facility in which she works and showed off the extensive fly development collection in her lab. In the end, attendees were left with Pollock-esque works they could take home to show their friends and family - with a perfect backstory about bugs just in time for Halloween.

Insects of Central Park with Dr. Harald Parzer

On a sunny Saturday, September 17, twenty-three natural historians joined Dr. Harald Parzer in Central Park to learn about insects. Parzer showed participants how to identify members of this astonishingly species-rich group of arthropods: three body parts (head, thorax, and abdomen) with three pairs of legs on the thorax. After this introduction, basic sampling techniques were presented, including the well-known butterfly nets, but also more obscure techniques, such as inhaling them with an aspirator or luring them into pitfall traps. A student insect collection demonstrated how insects are preserved and the importance of properly labeling collected specimens. At Shakespeare’s Garden, butterfly nets were provided so that attendees could practice their newly learned insect catching skills. The insects frequently outwit participants, but attendees were still able to catch and observe plenty of insects. One tagged male monarch butterfly was spotted feeding in the garden. There were also plenty of white cabbage butterflies (Piers rapae), which could be easily sexed using the number of black dots on the front wings. Other insects observed include skippers (Hesperidae, with the jet-like rested wings), giant carpenter bees (Xylocarp sp.), leaf beetles (Chrysomelidae), honey bees (Apis mellifera), yellow jackets (Vespula sp.), and the ubiquitous hoverflies (Syrphidae), some of which mimic wasps with their yellow-black abdomen. After talking about the importance of having native wildflowers for pollinators, Parzer discussed some of the extraordinary monarch butterfly (Danaus plexippus) biology and the dramatic decline of overwintering individuals in Mexico. We finally moved to another site, observing large milkweed bugs (Oncopeltus fasciatus) on a native milkweed stand planted by Central Park parks department.

Guided Night Hike to Mount Beacon with arachnologist Dr. Stephanie Loria

On Saturday, July 16, The Metropolitan Society of Natural Historians embarked on a guided evening hike to Mount Beacon led by arachnologist Dr. Stephanie Loria. We learned about arthropod diversity, evolution and reproduction. Along the way, we spotted hundreds of gypsy moth adults, pupae and eggs on the trees. Gypsy moths are an invasive species defoliating the forests of eastern North American. Once at the summit and while enjoying the beautiful sunset, Loria showed us some exciting North American arachnid, insect and myriapod specimens from her teaching collecting. We then descended down in the dark and spotted some brightly fluorescent mushrooms, partially fluorescent millipedes, orb weavers, a click beetle, a frog, harvestmen and long horned-beetles.

Dr. Stephanie Loria is president and co-founder of the MSNH and is a member of the Scorpion Systematics Research Group at the American Museum of Natural History (AMNH). She received her B.S. at Sewanee: The University of the South where she studied population genetics of cave millipedes and completed her Ph.D in December 2015 at the Richard Gilder Graduate School at the AMNH with world-renowned scorpion expert Dr. Lorenzo Prendini. Dr. Loria's research focuses on the diversity and evolution of South and South-East Asian scorpions. She has traveled across the globe for her Ph.D research collecting scorpions and studying specimens in natural history museums.

Guided Tour of the NY Aquarium with ichthyologist Allison Bronson

On Sunday, June 19, ichthyologist Allison Bronson led us on a guided tour of the NY Aquarium. Bronson taught us a lot about fish and coral reefs including how catfish smell, what causes coral bleaching, how to sex sharks, and the evolution cichlids in Lake Victoria. We also saw a nice diversity of fish from all over the world including green moray eel, cownose ray, sand tiger shark, clownfish and some other vertebrates including sea lions, black-footed penguins, river otters and a Pacific walrus. 

Allison Bronson is a Ph.D. student at the Richard Gilder Graduate School of the American Museum of Natural History. As an undergraduate at Humboldt State University in California, she worked on numerous projects including describing new species of extinct fungi and plants, the evolution of smell in toxic newts and predation in marine snails. For her Ph.D., Bronson is studying the evolution of early sharks using fossils and CT scanning. She is also examining the evolution of smell in catfishes from the Congo River Basin.

Lichens in Central Park

On Sunday, April 17, The Metropolitan Society of Natural Historians was led by lichenologist, Jessica Allen from the New York Botanical Garden on a lichen tour in Central Park. We came across several species of lichens growing on rocks and trees that have been largely undisturbed by the throngs of people who frequent the park. Lichens can be found growing throughout the world in some of the most extreme environments, however they are particularly susceptible to pollution. Those that we came across are some of the few that can tolerate pollution. A full species listing of lichens in Central Park can be found in the online field guide created by Allen.
