Monitoring Horseshoe Crab Breeding with NYC Audubon

On Friday, June 9, the MSNH joined NYC Audubon in their annual survey of horseshoe crab breeding in Jamaica Bay. The weather was perfect on this full moon night and as the sky darkened we saw lots of male horseshoe crabs come in with the tide searching the shallow waters for females. We witnessed several males trying to latch onto a single female hoping to externally fertilize her eggs. We were lucky enough to see some eggs in the sand which looked like beautiful tiny green marbles. We also saved a sea robin which had been abandoned on the beach by nearby fishermen and released it back into the water where it fanned out its dragon like fins. NYC Audubon's annual horseshoe crab survey is crucial for monitoring the population of these magnificent ancient arthropods, which are in decline due to overharvesting for medical and fishing purposes. A special thank you to Dottie, NYC Audubon and to all participants for such a wonderful event!

Horseshoe crabs, despite their name and superficial resemblance, are not crabs. They actually belong to their own class Xiphosura in Chelicerata, an arthropod group that also includes the classes Arachnida (spiders, scorpions, ticks, etc), Eurypterida (the extinct sea scorpions and also MSNH's logo taxon), and Pycnogonida (sea spiders). Worldwide only four extant species of horseshoe crabs exist and all species except the Atlantic horseshoe crab, Limulus polyphemus, are found in the Indo-Pacific Ocean. Extinct horseshoe crab species have also been described and the oldest fossil, found in Canada, dates to the Upper Ordovician, 445 million years ago! Despite their remarkable old age, horseshoe crabs have changed little morphologically since their first appearance and are therefore often referred to as 'living fossils' in the scientific literature. To learn more about horseshoe crabs, check out our taxon of the month for April!

Songs of Trees with award winning author and ecologist Dr. David Haskell

On Saturday, June 3, the MSNH visited a Bradford pear tree on the busy northwest corner of 86th Street and Broadway with awarding winning author and ecologist Dr. David Haskell. This tree, which goes unnoticed by hundreds of pedestrians every day, is one of many trees featured in Haskell's latest book, The Songs of Trees. During the event, Haskell explained the origins of this Bradford pear tree and highlighted the ways in which this individual tree, and many other trees in the city, interact with their environment. For example, Haskell explained how trees like this one save the city millions of dollars each year by keeping the sidewalks cool in the summer heat and providing protection from flooding. They also help control air pollution and act as a river bank where people can step aside to take a break from the ongoing pedestrian traffic. Participants then engaged in activity where they got to use their five senses to examine a tree of their choosing taking time to experience the natural world around them that most people take for granted. To learn more about the The Songs of Trees, check out Ed Yong's interview in The Atlantic and Paul Kvinta's profile in Outside Magazine.

Dr. David Haskell is a biology professor at Sewanee: The University of the South. He received his B.A. from the University of Oxford and his Ph.D. from Cornell University. Haskell's first book, The Forest Unseen, was winner of the National Academies’ Best Book Award for 2013 and finalist for the 2013 Pulitzer Prize in nonfiction, among other honors. A profile by James Gorman in The New York Times said of Haskell that he “thinks like a biologist, writes like a poet, and gives the natural world the kind of open-minded attention one expects from a Zen monk rather than a hypothesis-driven scientist.”

Botany Walk in Central Park with NYBG botanists Daniel Atha and Richard Abbott

On Saturday, May 6, botanists Daniel Atha and Richard Abbott from The New York Botanical Garden, led the MSNH on a guided botany walk through Central Park. Atha began by describing the interesting history of Manhattan's landscape, particularly Central Park and Upper West Side to help us understand the ecology of the area. We then ventured into the park to see both native and non-native plant species and learned which characteristics (e.g., leaf shape and bark color) are used to identify them. Abbott discussed the differences between spontaneous plants which are plants that are not planted by humans and invasive or non-native plants, which are plants that are not native to an area. Many non-native plant species are able to outcompete native plant species because humans have drastically modified the landscape making it difficult for native species to survive. We also learned ways that the public could get involved (see links below) in helping botanists monitor the flora of the NY region.

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. 

If you have any questions related to this event, you can email Dr. Parzer directly at hparzer@outlook.com.

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.

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.
