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. 

To learn more about arachnids, check out the Arachnids book by arachnologist Jan Beccaloni from the Natural History Museum in London.

A great resource for insect identification is Bug Guide.

For millipede identification, great resources are available on Milli-PEET.

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.

To learn more about Bronson and her research visit here or watch her in this great video, Six Extinctions in Six Minutes, which is part of the Shelf Life video series of the American Museum of Natural History

As Bronson mentioned, the world's ocean biodiversity is at risk of extinction as humans continue to over-harvest fish and other animals for food. To learn how to eat seafood consciously, check out Sea Food Watch and their seafood recommendations app. Additional information on conserving the world's ocean biodiversity can be found here.

Spencer Galen is a Ph.D. candidate at the Richard Gilder Graduate School of the American Museum of Natural History. He received his B.S. from the University of Delaware and an M.S. from the University of New Mexico where he studied the evolution of birds in the Peruvian Andes. Galen has spent time studying birds throughout North and South America, including Costa Rica, Ecuador, Peru, and most recently Cuba. He is originally from New Jersey where he found a passion for studying birds as a child while observing the amazing spring migration that takes places across the eastern United States every year. Presently, his Ph.D. focuses on the evolution of malaria parasites in birds. To learn more about Spencer and his research, please visit his website here.

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.

Geology of Manhattan Skyscrapers

On Sunday, April 3, Jasmine Bayron, Ph.D. student at the CUNY Graduate Center and American Museum of Natural History, led the MSNH on a walk through Central Park. She showed us evidence of glacial recession (which can be seen in the striations of Umpire Rock) and pointed out the erratics left behind by these glaciers. After leaving the park, we examined many small invertebrates in the fossiliferous limestone of Upper East Side buildings. Several of the fossils we observed were bivalves, brachiopods, crinoids and bryozoans.

4th Annual Symposium

On Sunday, February, 28th, The Metropolitan Society of Natural Historians hosted its 4th Annual Symposium in collaboration with the Science Research Mentoring Program (SRMP) of the American Museum of Natural History (AMNH) in the Linder Theater at the AMNH. The SRMP program provides New York City high school students with an opportunity to undertake year-long research projects with AMNH scientists making them more confident and better equipped to pursue their research interests upon entering university. The symposium consisted of 10-minute presentations by 8 researchers from renowned institutions across the tristate area including the AMNH, Princeton University and the New York Botanical Garden. Topics included understanding how fish are able to detect water currents, understanding the paleodiet of our extinct primate relatives, using jaguar scat for conservation efforts, identifying cryptic diversity of orchids and much more. With over 90 attendees, including 49 students from the SRMP program, this was our largest symposium yet! We would like to thank Dr. Mark Weckel and Dr. Rae Wynn-Grant of the AMNH for assistance with organizing, Allison Bronson of the AMNH for helping with logistics, all presenters and attendees for participating, and the Doris Duke Charitable Foundation for supporting conference participation by SRMP students.

Dinosaur Hall Tour at AMNH

On Saturday, January 30th, The Metropolitan Society of Natural Historians was led on a wonderful tour of the American Museum of Natural History's dinosaur exhibit, featuring the latest and largest addition, the Titanosaur spanning 120 feet long from top of the head to tip of the tail. We were led by dinosaur expert, Danny Barta who expounded on the evolution of dinosaurs, and the hypotheses concerning their end and their evolution into the birds around us today. We learned the differences between the two major groups of dinosaurs: ornithischians and saurischians and listened to Barta describe his own research on dinosaur reproduction, growth and development.

NY Eats Bugs


On Saturday, November 21, The Metropolitan of Natural History, The New York Entomological Society, Alimentary Initiatives and The Explorers Club hosted NY Eats Bugs at The Explorers Club on east 70th street between Park and Madison Avenues. During the first half, Crickets and Cocktails, guests enjoyed a variety of hors d’oeuvres and cocktails in the library and on the terrace featuring several edible insects including crickets, mealworms, and water bugs and a special entomophagy cocktail known as Cricket Bitters. After the cocktail hour, guests gathered into the Clark room to listen to presentations given by Dr. Phil Barden, a paleoentomologist from Rutgers University and Katharina Unger, an entrepreneur in entomophagy with Baron Ambrosia, host of the show The Culinary Adventures of Baron Ambrosia, acting as the MC. The second half of the event, New York Banquet of Bugs, featured a six-course dinner prepared by chefs Natalia “Cookie” Martinez from Toronto and Mario Hernandez from The Black Ant restaurant on the lower east side.
