Exhibition: Drawn to Paint: Paintings of Arboretum Trees

Fri May 10 (All day) to Sun Jul 21 (All day)

Location: 

Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston

Artist, Paul Olson, has been discovering the nuances of the Arnold Arboretum’s collections since he first passed through its gates in 2011. A landscape painter for decades, Olson explores the grounds with sketchbook in hand, typically in the early morning hours. His goal is to be unencumbered by any agenda and open to what the light of the day presents. In 2012, he had an exhibition at the Arboretum titled “Drawn to Woods.” The expressive ink drawings in that show were all completed en plein air—on-site in the open air.

In this new exhibition, Olson brings his on-site...

Ethnobotany at Harvard

12:00pm to 2:00pm

Location: 

Harvard University Herbaria, 22 Divinity Ave., Cambridge

Historically, plants have provided humans with most of our drugs, fibers, food, dyes, perfumes, building materials, and even musical instruments. But how has this diverse and fascinating field been studied and what has been learned? In fact, for over 100 years, Harvard has played a pivotal role in the study of human-plant interactions, leading to the creation of the field of ethnobotany.

In this interactive lecture we will explore the science and history of some of the most important Harvard botanists and explorers through their unique specimens—now housed in the Harvard...

How does an egg become an egg? Why do chickens continue to lay eggs day after day? What controls the shape of eggs? Why do eggs of different species of birds have different colors? And how strong are eggshells?

In this talk which follows previous talks about bird flight, migration, and feathers, Lorna Gibson answers common questions about bird eggs.

Landscape Plant Selection, Planting, and Establishment

1:00pm to 3:30pm

Location: 

Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston

Ensuring the long-term health of your landscape starts with healthy plants from the nursery, proper site selection and preparation, and sound planting and establishment.

Film Screening: Lobster War: The Fight Over the World's Richest Fishing Grounds

6:00pm to 8:00pm

Location: 

Geological Lecture Hall, 24 Oxford St., Cambridge

Lobster War is an award-winning documentary film about a conflict between the United States and Canada over waters that both countries have claimed since the end of the Revolutionary War. The disputed 277 square miles of sea known as the Gray Zone were traditionally fished by U.S. lobstermen. But as the Gulf of Maine has warmed faster than nearly any other body of water on the planet, the area’s previously modest lobster population has surged. As a result, Canadians have begun to assert their sovereignty, warring with the Americans to claim the bounty.

Lecture: Chasing Ants (And Their Microbes) in the Rainforest

6:00pm

Location: 

Geological Lecture Hall, 24 Oxford St., Cambridge

Microbes play critical roles in the biology and health of human beings, but we are not the only species that benefits from intimate relationships with microbes. Ants, for instance, rely on the microbial communities living in their guts to process food and make strong armor.

Corrie Moreau will discuss this unique aspect of ant biology and what it tells us about the diversity and dominance of ants in terrestrial ecosystems, the evolutionary history of social insects, and the broad-scale evolutionary patterns of life.

Lecture: Self-Domestication in Bonobos and Other Wild Animals

6:00pm

Location: 

Geological Lecture Hall, 24 Oxford St., Cambridge

Domesticated animals such as dogs, pigs, and horses often sport floppy ears, patches of white hair, and other features that are unknown in their wild ancestors. These traits—collectively referred to by scientists as a “domestication syndrome”—are the result of breeding less aggressive individuals.

Drawing from his new book, The Goodness Paradox (2019, Pantheon Books), Richard Wrangham will show that our cousin apes, the bonobos, also exhibit a domestication syndrome, making them the first clear example of a “wild domesticate.” Self-domestication in the wild now seems...

Around the World in 80 Trees

7:00pm to 8:15pm

Location: 

Weld Hill Building, Arnold Arboretum, Boston

Trees are one of humanity’s most constant and varied companions. From India’s sacred banyan to the fragrant cedar of Lebanon, they offer us sanctuary and inspiration – not to mention the raw materials for everything from aspirin to maple syrup.

In Around the World in 80 Trees, Jonathan Drori uses plant science to illuminate how trees play a role in every part of human life, from the romantic to the regrettable, to the downright ridiculous. Stops on the trip include the lime trees of Berlin’s Unter den Linden boulevard, which intoxicate amorous Germans and hungry bees...
