Climate change touches every life on the planet — so why are so many environmental scientists white men?

Last year, UCLA became the first university to launch a center for diversity in environmental science to counter the problem. Its goal: to inspire a generation of leaders that actually matches the demographics of the U.S. population.

This year, the Center for Diverse Leadership in Science’s first class of fellows takes flight, building a critical mass to ensure students and faculty of diverse backgrounds have what they’ll need to succeed, from funding to a supportive community of scientists with similar backgrounds.

“With challenges like climate change, the stakes have never been higher for ensuring we have scientific literacy coupled with representation and innovation,” said Aradhna Tripati, the center’s founder and a UCLA climate scientist. “We need every person’s imagination to overcome some of the greatest challenges our society has faced.”

Karen McKinnon, a professor in the UCLA Institute of the Environment and Sustainability knows only too well how that sense of isolation affects a student. As one of just a few women in her doctoral program, McKinnon experienced first-hand what it’s like to be a minority in an academic setting.

“The experience of having only a small number of female peers was challenging because you always felt just a little bit out of place,” said McKinnon, who is also a professor of statistics. “It was a visual reminder that I was not the ‘typical’ scientist.”

In the United States, 86 percent of the environmental science workforce is white and 70 percent is male, despite the fact that the EPA found in a 2018 study that non-white communities had a 28 percent higher health burden from environmental issues. Those under the poverty line had a 35 percent higher health burden.

The inaugural fellows class consists of 47 high school, undergraduate students, graduate students and postdoctoral researchers, along with 22 faculty fellows from UCLA. The students will work in groups on research and outreach campaigns while the faculty fellows serve as mentors and role models.

The fellows aim to break barriers that prevent women and minorities from pursuing academic careers in the sciences through group collaboration, workshop training sessions and community outreach. Students are paid for their work with financial support from the National Science Foundation and private donations.

Ronald Thompson, a second-year environmental science student from Sacramento, said he is one of few black students in most of his classes.

“Diversity provides comfort in a work environment and shows that you can do anything despite your race, religious beliefs or sexuality,” said Thompson, who wants to pursue a research career in conservation biology. “It lets you be comfortable with what you’re doing and makes you feel like you’re not being judged or looked at differently.”

For his research component of the fellowship, Thompson works with other undergraduates in a group overseen by a doctoral candidate to analyze sediment from ancient lakes across the western United States. Their research aims to discover how those lakes persisted through past changes in climate — and how they might react to modern climate change. While the work is fulfilling, Thompson said the best part is working with others just as passionate as himself about the environment.

“People go above and beyond what is required of them out of pure passion for the work they do,” Thompson said. “Everyone wants to be a part of the change that promotes a better future.”

Next year, Thompson will be paired with a faculty fellow for one-on-one mentorship, a cornerstone of the fellowship program.

Tripati said that having a continuum of scientists at all levels — from high school students to professors — is an effective strategy to build professional communities that are inclusive of all forms of diversity: gender, sexual orientation, gender identity, race and ethnicity.

Lack of diversity in such programs can have global implications when it comes to environmental issues, she added.

“If you don’t have women in science, you’re missing some of that talent pool,” McKinnon said. “There remain a lot of fundamental questions to answer about how the climate system responds to human influence.”

One way to make students more comfortable in class is to encourage teachers to embrace inclusive teaching techniques, said Jasper Kok, who is one of the faculty fellows and an associate professor of atmospheric and oceanic sciences in the UCLA College. Every class includes a 10-minute exercise during which students work with their neighbors.

“Techniques that engage students and let them work collaboratively help those students who feel like they don’t belong feel more at home and more likely to stay in that field,” he said.

For student fellow Thompson, the benefits are more personal.

“It’s an opportunity to give back to communities and be a role model to other college students, high school students and middle school students,” he said.

Painted Lady Butterfly

UCLA aflutter over the butterfly effect

Painted Lady Butterfly

You’ve seen the butterflies fluttering across Los Angeles and speeding through campus. You’re likely to see them for another couple of weeks, according to research scientist Jeff Holmquist, a community ecologist at the UCLA White Mountain Research Center and the UCLA Institute of the Environment and Sustainability.

Holmquist explained in an interview why there are so many butterflies this year and why he’s betting on this species despite climate change. He also clarifies that the migration has nothing to do with the wildflower super bloom, and why that yellow splat on your windshield is the same thing that helps the butterflies make their migration — and what makes butterflies a nutritious snack.

Where are these butterflies coming from?

These are painted lady butterflies. They have a famous migration pattern. They winter in various places in northern Mexico and Southern California like the Mojave Desert. They prefer open habitat like desert, sage growth and meadows.

Why are we seeing so many in Los Angeles right now?

The big migration years seem to be in wet years, when there’s a lot of food for the caterpillars. Big rain years like the one we just had are just huge for the forage plants that they eat. So the female will lay individual eggs on plants, and they hatch in about 5 to 7 days. The caterpillars just eat and eat for a few days, then make a chrysalis.

I’ve been studying invertebrates my whole career, and butterflies are just extraordinary. To reorganize the body like that takes a huge amount of energy. You may as well imagine eating like crazy for a week, crawling into a sleeping bag for a few weeks, and coming out as an eagle.

They’re flying north where it’s temperate to lay eggs.

Do they migrate every year?

Normally we see a few here, a few there, but yes, there’s always a migration. They’re very fast fliers. They can go about 20 miles per hour, and they’ve been clocked at 25. If I can maintain about 25 miles per hour on my bike, I can fly along with the butterfly flight. It’s quite fun. I’m looking forward to the migration making it north where I am in a few weeks. They also have a return migration that tends to be at high altitude. There’s some mystery there, because it’s really unknown by scientists how frequently they migrate at high altitude. We may be missing some of the picture because they fly quite high.

[Editor’s note: the White Mountain Research Center where Holmquist works is about 260 miles north of UCLA, close to California’s eastern border.]

Are they attracted by the super bloom of wildflowers in Southern California right now?

It’s more that they fly at the same time that flowers bloom. As you’ve seen, they’re on a mission. They’re not stopping to feed. Right now, they’re living on their fat reserves. They’re very good at turning their food into energy in the form of lipids — that is, fat. They have to take a backpack full of food, essentially, to make this migration, and for them that’s an abdomen full of fat. If you see them hit your windshield, you’ll see that yellow splat, and that’s the lipids.

Fat reserves are very important for a lot of insects, and that’s part of why many societies are rediscovering them as food right now, or have traditionally eaten them. Butterflies are very fatty.

I’ve heard of insects as high-protein, but not fatty.

Oh yeah, they’re like little chicharrones. I have a project going right now with our local Paiute tribe, and butterflies are an important traditional Native American food. The Paiute use a different species, but they catch the caterpillars, then roast, salt and boil them, and they preserve very well throughout the year.

Is the change in this year’s migration related to climate change?

My sense is that over time we can expect to see earlier migrations, as the climate warms. I’m not sure this year’s is early, though. And there’s the unknown factor of rain. A lot of butterfly booms are cyclical, but this one is really driven by rains. In a year with more rain, we would anticipate another large migration.

 

 

Are there other ways that climate change could interfere with painted ladies?

It’s possible. They might get too hot earlier. But I wouldn’t bet against the painted lady. It’s probably the world’s most widely distributed butterfly, living everywhere but South America and Antarctica. It’s very well-adapted. There’s a very large migration in Eurasia that’s even more striking than what we have right now, and one that goes from the Sahara to England.

A lot of species are very specific in their choice of host plants, but painted ladies aren’t picky. They’re real generalists. They eat lots of thistles, sage, sunflower and mallow plants. So they’re fine. But we’re in danger of losing so many other species.

As long as people have butterflies on the brain right now, what can they do to support butterflies and biodiversity?

Plant some milkweed. While painted ladies eat lots of plants, monarch butterflies need milkweed. People need to plant the native northern milkweed — the southern, more tropical milkweeds don’t have the same seasonal cycle, and that may remove an important migration cue for monarchs. Other than that, any good nectar plants are good for a butterfly garden.

For painted ladies, maybe slow down a little if you see them while you’re driving. I brake for butterflies. But that may not be the thing to do on the freeway.

Any other advice about the migration?

Enjoy it. This is nature’s fireworks display.
