    The Ancient Maya Response to Climate Change: A Cautionary Tale

    6:00pm

    Location: 

    Geological Lecture Hall, 24 Oxford St., Cambridge

    Ancient Maya civilization—known for its cities, monumental architecture, ceramics, hieroglyphic writing, and advanced understanding of mathematics and astronomy—suffered a major demise between the tenth and eleventh centuries. The causes continue to be investigated and debated. Paleoenvironmental research over the past twenty years has revealed that the demise coincided with a prolonged intensive drought that extended across the region, providing compelling evidence that climate change played a key role in the collapse of the Maya.

    In this lecture, Billie Turner will examine...

    The Secret Lives of Roots

    2:30pm to 4:00pm

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    The Arnold Arboretum is full of spectacular specimens from around the world that any visitor will appreciate. However, what they observe is only half the story. How a tree uptakes water and nutrients, stays grounded in place, stores energy, and sometimes even propagates itself, is all thanks to its roots. Join horticulturists Andrew Gapinski and Conor Guidarelli as they unearth these questions and more during an exclusive look into the extraordinary world of roots.

    Small Trees for Small Spaces

    10:00am to 12:30pm

    Location: 

    Hunnewell Building and Landscape, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...

    Can Baby Corals Improve the Reefs of Tomorrow?

    6:00pm

    Location: 

    Geological Lecture Hall, 24 Oxford Street, Cambridge, MA

    Aaron Hartmann, 2017–2018 Sarah and Daniel Hrdy Visiting Fellow in Conservation Biology, Department of Organismic and Evolutionary Biology, Harvard University

    Coral reefs are one of Earth’s most biodiverse and imperiled ecosystems. Corals form the foundation of this ecosystem. Substantial effort is being invested to help adult corals survive environmental degradation, but less attention is paid to their offspring and how they establish themselves on the seafloor. Unlike adult corals, baby corals move about in the water column, perhaps allowing them to...

    Back by popular demand with more content! Terry Huang’s bawdy botanical review delves into the sex lives of plants, dramatically explaining the challenges of courtship and consummation for those rooted in place. Alluring suitors with a pungent rotten odor, promising nectar for the exchange of goods, or going at it alone, plants have evolved interesting strategies to ensure their continued existence. From mutualistic partnerships to deceit-filled...

    6:00pm

    Location: 

    Geological Lecture Hall, 24 Oxford Street, Cambridge, MA

    Biodiversity is the sum total of life on Earth and a living legacy to future generations. Sadly, it is declining almost everywhere on the planet. Russell A. Mittermeier, recipient of the 2018 Indianapolis Prize, is a biologist and lifelong conservationist who has traveled across 169 countries and discovered more than 20 species in his quest to save biodiversity hotspots. Focusing on nonhuman primates—our closest living relatives—...

    1:00pm to 2:30pm

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston

    Many plants that we consider to be weeds have rich ethnobotanical histories of their own that tie us closer to our environment. Your guides will explain how these "weedy" plants came to colonize this area while touching on cultural contexts and botanical identification of these wild species—as well as the cultivated medicinal species in the Leventritt Shrub and Vine Garden. Guides: John de la Parra, Associate, Harvard University Herbaria; Ernest Anemone, Co-Guide;...

    Saving Coral Reefs in the Florida Keys

    6:00pm

    Location: 

    Geological Lecture Hall, 24 Oxford Street, Cambridge MA

    James W. Porter, Josiah Meigs Distinguished Professor Emeritus, Odum School of Ecology, University of Georgia

    Coral reefs support more than a quarter of all marine life, yet many are critically endangered. In the Florida Keys, the once common elk horn coral (Acropora palmata) has experienced steep declines since the 1970s. Preliminary blame was attributed to global warming and coral bleaching, but in fact, a human bacterial pathogen associated with a wide range of serious infections was the culprit. James Porter will discuss how Key West residents are saving these reefs...
