Monarch butterflies with more white spots are more successful at reaching their long-distance wintering destination, a new study suggests.
Although it’s not yet clear how the spots aid the species’ migration, it’s possible that the spots change airflow patterns around their wings.
“We undertook this project to learn how such a small animal can make such a successful long-distance flight,” says Andy Davis, an assistant researcher in the Odum School of Ecology at the University of Georgia and lead author of the study published in PLOS ONE.
“We actually went into this thinking that monarchs with more dark wings would be more successful at migrating because dark surfaces can improve flight efficiency. But we found the opposite.”
The monarchs with less black on their wings and more white spots were the ones that made it to their ultimate destination, nearly 3,000 miles away in south and central Mexico.
“It’s the white spots that seem to be the difference maker,” Davis says.
The researchers analyzed nearly 400 wild monarch wings collected at different stages of their journey, measuring their color proportions. They found the successful migrant monarchs had about 3% less black and 3% more white on their wings.
An additional analysis of museum specimens that included monarchs and six other butterfly species showed that the monarchs had significantly larger white spots than their nonmigratory cousins.
The only other species that came close to having the same proportion of white spots on its wing was its semi-migratory relative, the southern monarch.
The authors believe the butterflies’ coloring is related to the amount of radiation they receive during their journey. The monarchs’ longer journey means they’re exposed to more sunlight. As a result, they have evolved to have more white spots.
“The amount of solar energy monarchs are receiving along their journey is extreme, especially since they fly with their wings spread open most of the time,” Davis says. “After making this migration for thousands of years, they figured out a way to capitalize on that solar energy to improve their aerial efficiency.”
But as temperatures continue to rise and alter the solar radiation reaching Earth’s surface, monarchs will likely have to adapt to survive, says coauthor Mostafa Hassanalian, an associate professor at the New Mexico Institute of Mining and Technology.
“With greater solar intensity, some of that aerial efficiency could go away,” Davis says. “That would be yet one more thing that is hindering the species’ fall migration to Mexico.”
But it’s not all bad news for the flying insects.
Davis’ previous work showed that summer populations of monarchs have remained relatively stable over the past 25 years. That finding suggests that the species’ population growth during the summer compensates for butterfly losses due to migration, winter weather and changing environmental factors.
“The breeding population of monarchs seems fairly stable, so the biggest hurdles that the monarch population faces are in reaching their winter destination,” Davis says. “This study allows us to further understand how monarchs are successful in reaching their destination.”

Welcome back to Found, where we get the stories behind the startups.
This week Darrell and Becca are joined by Ben Lamm, the founder and CEO of Colossal, a genetics startup that looks to bring extinct species back to life to help with environmental conservation efforts. Ben talked about how he got to this point in his career after starting numerous other companies in the AI, gaming and space sectors. He talked about why Colossal chose to start its de-extinction efforts with the mammoth and why de-extinction is about way more than just bringing the species back. Plus, he talks about why they structured the experimental startup like a software company.

Last week, the U.S. Federal Trade Commission, which protects consumers from deceptive business practices, issued an advisory titled “Keep your AI claims in check.”
When it comes to marketing, “false or unsubstantiated claims about a product’s efficacy are our bread and butter,” wrote Michael Atleson, an attorney with the FTC’s Division of Advertising Practices.
Artificial intelligence is a on everyone’s lips at the moment, “and at the FTC, one thing we know about hot marketing terms is that some advertisers won’t be able to stop themselves from overusing and abusing them.”
Given the renewed interest, “for companies where AI was previously No. 4 on the list of proof points, machine learning capabilities should merge into the main hook of the announcement,” advises PR strategist Camilla Tenn.

“If AI-related coverage can get a new, unknown brand into its target publications today, it could help get the brand’s pitch deck in front of potential investors or partners tomorrow,” she writes in TC+.
Tenn recommends imitating major players like Google and Samsung, which have dedicated teams that release a steady stream of material about “ongoing projects” tied to prevailing tech trends.
“Even if those projects don’t see the light of day, the PR team has strategically positioned the brand as ‘innovative,’” says Tenn. “With this precedent, startups should not feel abashed to use any means necessary to get their name out there.”
Good advice for marketing mercenaries, but keep those pitches straight — reporters know when we’re being sold to, and the FTC isn’t messing around.

Dear Sophie,
I started working for my current employer on STEM-OPT, but I’ve lost out in the H-1B lottery four times. Thankfully, my employer transferred me to an international office, and I am now coming back to the U.S. on an L-1 visa.
I’ve heard many complaints from my classmates about not being able to switch employers on an L-1 visa. I don’t see myself staying at my employer for six more years, which is the estimated time until I can get a green card based on my employer’s internal policy.
What are my options for changing my immigration status so I can work at a startup in the U.S. within a year or two?

No one needs a mega-influencer like Serena Williams or a Kardashian to build buzz for their startup — an evangelist with just a few thousand followers can push qualified customers into your product funnel.
But before hiring a TikTok or YouTube personality, brand marketers should brush up on the laws that govern how influencers operate, and the risks associated with failing to comply.
“Novel legal issues and risks have emerged for both influencers and brands,” says Nicholas Sandy, a litigator at Pryor Cashman.
“Key, recurring issues relate to copyright licensing and infringement, disclosures and statements in endorsements, compliance with securities laws, and defamation.”

TechCrunch+ roundup: Ocean tech investor survey, AI and PR, L-1 visa options by Walter Thompson originally published on TechCrunch
Climate change is a problem important and pressing enough that investors have begun to grasp the opportunities that arise when trying to solve it. Now, they’ve started to cast their nets wider for other, adjacent opportunities.
Tech that serves to conserve the oceans while using it to replace older, more harmful means of generating energy and food seems to be one such opportunity. In fact, when we asked 10 investors in the sector to share their thoughts on the space, we quickly learned that ocean conservation tech startups are seeing more and more interest from generalist investors now that climate change is hot and people are seeking more ways to mitigate its effects.
“Climate change used to be more focused on terrestrial operations. It is now ‘warming’ up to ocean conservation,” Daniela Fernandez, managing partner of Seabird Ventures, told TechCrunch.
The world’s oceans and its climate have always been tightly coupled. Winds generate ocean currents, which in turn influence weather patterns both over the open water and deep into the continents.
“Our planet is 70% ocean, so the urgency of facing and solving climate change can only be properly addressed if we include the ocean in the equation,” said Rita Sousa, partner at Faber Ventures.
The open ocean also contains tremendous amounts of energy. Previously, accessing it meant drilling into the ocean floor to tap hard-to-reach deposits of oil and gas. But today, it increasingly means tapping the enormous energy represented by the ocean’s winds and waves. Just offshore wind alone has the potential to meet global electricity demand by 2040, according to the IEA, which is well in excess of all offshore oil and gas production today.
Stephan Feilhauer, managing director of clean energy at S2G Ventures stressed the viability of technologies like offshore wind as commercial alternatives to fossil fuels: “Offshore wind has established supply chains across the globe. It is possible today to manufacture, install and operate gigawatts of offshore wind energy using technology and equipment that is well established and has years of operational data to help us understand its performance. Offshore wind is the only ocean-based renewable technology that meets these criteria today.”
The oceans are constantly exchanging gases with the atmosphere, too; most importantly withdrawing and storing about 30% of all carbon dioxide pollution. The ocean’s capacity as a carbon sink has created problems for myriad marine life, which have depended on historically stable acidity levels that are now creeping higher. However, this very capacity also creates opportunities to put key nutrient cycles to work and capture humanity’s excess emissions.
“A healthy ocean will continue to provide crucial opportunities for carbon sequestration,” said Peter Bryant, program director (oceans) at Builders Initiative. “There are a number of opportunities for increasing the ocean’s ability to store carbon. We have biological approaches that include ecosystem restoration, seaweed cultivation and iron fertilization; chemical solutions where you use minerals to lock dissolved carbon dioxide into bicarbonates; and electromagnetic approaches that store carbon by running electric currents through seawater.”
Founders and investors have a growing appreciation for the ocean’s potential as a resource for renewable energy and its capacity to buffer and even solve some of the climate problem. “We’re confident in the ocean’s resilience here. It’s simply one of the best resources we have in the fight against climate, and that means opportunity,” said Reece Pacheco, partner at Propeller. “We won’t achieve our climate goals without the ocean. Full stop.”
Christian Lim, managing director at SWEN Capital Partners, agreed: “It took too much time, but finally the ocean is being recognized as a critical piece of our fight against climate change.”
We spoke with:
Climate change is the elephant in the room. Has the issue’s rising profile sucked the air out of the room or is it bringing attention to ocean conservation that otherwise wouldn’t be there? How have things changed in the past five years?
Climate change has been a topic for decades. It used to be a “nice to have” about a decade ago: “If you have the extra funds to perform climate risk assessment, then we will dedicate it to climate change.”
Now, it’s more of a “must have.” If we don’t address climate change, we’ll see more extreme weather events. Over the past five years, we’ve seen more focus on ocean conservation, but there is still a $149 billion annual ocean funding gap. Climate change used to be more focused on terrestrial operations. It is now “warming” up to ocean conservation.
We are just now beginning to see a distinct shift in tone. The thinking used to be that “the ocean is a victim of climate change,” but now the thought is more “the ocean can become a climate hero” and plays a huge role in reducing our carbon footprint. Yet, this shift is still very much in its infancy. In particular, the philanthropic community is just starting to recognize that there is an urgent need to support efforts to develop ocean-based climate solutions.
Until now, most climate funders focused on terrestrial or atmospheric issues, and ocean funders focused on important, but only tangentially climate-related ocean issues such as ending unsustainable fishing practices and establishing marine protected areas. The ocean is already the biggest carbon sink on the planet, and we need to better understand both what absorption of all that carbon is doing to ocean ecosystems, and how much more it can potentially contribute without disrupting its other critical ecosystem functions.
It’s also been encouraging to see governments taking action to truly prioritize and create financial incentives for investing in climate/ocean innovations, such as the bipartisan Infrastructure Law passed in the U.S. in 2022. There is also an upswell of talent realizing that working a “typical” job is no longer an option if we won’t have a livable planet in the next seven years. We are seeing society reset its priorities and climate is one of the highest ones at the moment.
Climate change has been called “recession-proof” because governments and investors have come to recognize the scope, scale and urgency of the issue. Do you think that’s true of ocean conservation tech as well?
Yes. Climate change and ocean restoration are inherently linked. The ocean is humanity’s biggest protection against climate change, as it produces more than half the air we breathe and absorbs 93% of excess heat from global warming.
Ocean tech and climate change companies and investors all have the same goal. The urgency of the climate crisis has kept passionate funders and entrepreneurs engaged in the development of solutions regardless of the state of the economy.
Climate change has affected the oceans greatly, causing everything from rising water temperatures to more acidification. How are you approaching the question of climate change in your investments?
Seabird Ventures is internally tracking impact and reporting on social and/or environmental factors in our investments. We have externally reported on the following key ocean impact areas:
To fix the climate, these 10 investors are betting the house on the ocean by Tim De Chant originally published on TechCrunch
For an ecosystem that covers a majority of the planet, the oceans have basically been ignored by startups and investors alike.
Sure, plenty of money is spent on ocean-based industries, but most of today’s marine investments are into either extractive industries like fishing or oil and gas, or activities like shipping, which aren’t extractive but don’t exactly benefit marine ecosystems.
However, in recent years, there has been a sea change in perspectives. Founders and investors have started to look for opportunities to conserve, and even enhance, the ocean’s resources rather than exploit them.
“There is tremendous potential for the ocean to provide more food, more efficiently, with less environmental impact and even regeneratively,” said Reece Pacheco, a partner at Propeller.
Because the oceans take up so much of the planet and the space is relatively uncharted, there are plenty of opportunities for investors to find niches ripe with financial and environmental upsides.
“Our systems are at a point where it is more productive to work with nature than against it,” said Sanjeev Krishnan, chief investment officer at S2G Ventures. “While energy and agriculture are further along the J-curve, the oceans sector is more nascent but presents an investable opportunity that impacts almost every sector of the global economy.”
In that way, ocean conservation tech mirrors climate tech, which has been growing so fast that some have called it “recession-proof.” Of course, some question whether any sector is truly recession-proof and that applies to ocean conservation tech as well.
That doesn’t mean that investors aren’t bullish, though. “I’m not sure I would characterize the ocean economy as recession-proof, but the investment opportunities are real from a venture capital perspective,” said Tim Agnew, general partner at Bold Ocean Ventures.
Even some of the most intractable and high-profile problems facing the world’s oceans, like plastic pollution, are inspiring investors to dive in.
“People have been looking at solving these problems in the wrong way,” said Daniela Fernandez, managing partner at Seabird Ventures. “Profitability and scalability depend on the approach and business model that is being implemented to solve the plastic pollution crisis. We have to think beyond community beach cleanups — there are actually extremely investable approaches to solving the plastic problem.”
Investors like Fernandez are looking with fresh eyes at both new problems like plastic pollution and old ones like aquaculture and fisheries management. In the process, they’re betting that innovative approaches to solving those problems will not just create returns but create disruptions and innovations that spill over into adjacent sectors.
“Part of our thesis is that ocean conservation technologies can solve big problems for big ocean-going industries and adjacent industries,” said Kate Danaher, managing director at S2G Ventures.
But, she added, there’s still more room to grow. “We need to make the case to even more climate-focused and generalist investors.”
To get a better idea of how startups and investors are thinking about ocean conservation tech and the opportunities therein, we spoke with:
What is your investment thesis for ocean conservation tech in 2023? What sort of growth are you expecting in the sector?
Our investment thesis is focused on innovations that modernize the seafood supply chain, expand production in a sustainable way and address the impacts of climate change. We believe this investment opportunity is in its early stages and will be a major theme over the next decade as it becomes clearer how impactful the ocean can be in addressing the climate crisis and feeding a growing, more urbanized population.
Ocean-related businesses are at the beginning stages of adopting new technologies to increase efficiencies and productivity.
Is there a meaningful distinction between the tech used by startups focused on coastal regions and the tech built for the open ocean?
Answer is yes and no. Ocean shipping and ocean wind are obviously very different animals from kelp aquaculture and climate resiliency, but both are migrating toward more tech-enabled solutions, including digital technologies, artificial intelligence, data gathering and analysis.
A lot of the problems facing the oceans, like plastic pollution, don’t seem to have much potential for profit. Is that a fair assessment, or have we been looking at these problems in the wrong way?
We just looked at a company that has a booming business of gathering plastic bottles on beaches, separating the types of plastic and selling to companies that are anxious to be able to offer recycled bottles or other products.
There is considerable research going into the transition from plastic packaging to biodegradable packaging. There is plenty of potential for profitable businesses, although the process of cleaning up the oceans is going to require time and money.
What technology are you excited about that has the most potential to create new markets?
Seafood traceability solutions; ropeless traps; microalgae and seaweed are a hugely untapped resource with multiple market opportunities; ocean and weather data collection and analysis.
The ocean today only accounts for 15% of the world’s protein and 2% of its calories. What is the potential for the oceans to provide more, and what should that look like?
The oceans will provide more food that has a much lower carbon footprint than land-based animal protein. Shifting demand from beef to seafood could have a major impact on GHG reduction. Seafood aquaculture, both on- and offshore, is growing much faster than wild-caught seafood and will become a major source of high-quality protein.
What are some of the keystone problems that an ocean-based food system faces?
Social license concerns about aquaculture, species sustainability and the need to broaden consumer tastes to reduce pressure on overfishing.
From aquaculture to kelp farming, there is a range of options to get more food from the oceans. Which do you think is the most promising?
RAS and closed system aquaculture.
What is your investment thesis for ocean conservation tech in 2023? What sort of growth are you expecting in the sector?
Peter Bryant: We invest in technologies and business models that enhance the conservation, regeneration and resilience of ecosystems, optimize the production of and use of resources derived from the ocean, and provide consumers with a sustainable, traceable and secure food.
Kate Danaher: Part of our thesis is that ocean conservation technologies can solve big problems for big ocean-going and adjacent industries. Innovations that create deflationary solutions like saving fuel, lowering water usage or can build diverse revenue streams through multiple industries will be best positioned to weather this economic winter, raise capital and gain traction in the market.
As these types of innovations begin to show commercial results and have a positive environmental impact, we expect that investment in the sector will continue to increase, spurring more oceans-focused funds and increased interest from broader climate funds.
What role have impact investors played in ocean conservation? Investor networks?
Bryant: Within ocean conservation, there are technologies and entire subsectors that are still developing and need patient capital for R&D, reaching product-market fit, and in some cases, creating new markets. Patient capital lets commercially viable companies de-risk themselves and provide them with the runway they need to hit milestones to attract more traditional capital.
Impact investors have also catalyzed the growth of the ocean investment landscape by providing the first capital into ocean funds. Before 2018, there were only a handful of ocean-focused funds; however, in the last 18 months, more than 18 ocean-focused funds have been launched.
This is exciting not only because it will lead to hundreds of millions of new dollars invested in the oceans, but also because it demonstrates that venture and growth equity investors have seen the potential of oceans and are willing to set up funds with an oceans focus. Impact investors who are willing to invest early in these funds are playing a pivotal role in attracting the capital needed to grow the investment landscape in oceans.

Deforestation not only causes the loss of important natural resources, it also contributes to global warming. Deforestation is the cause of about 20 percent of carbon dioxide emissions globally, which is higher than both passenger vehicles and trucks emit.
Large-scale deforestation of the Amazon began several decades ago and has accelerated in recent years, placing Brazil among the countries with the most. But the loss of forests in South America is not an Amazon-specific issue. According to a recent report released by MapBiomas, Argentina has lost almost 20 percent of the Atlantic Forest in the last 37 years.
The Atlantic Forest is a region shared among Argentina (3 percent), Brazil (90 percent), and Paraguay (7 percent). It is composed of tropical and subtropical rainforests extending more than 3,000 kilometers along the Brazilian Atlantic coast and runs inland to the west for almost 1,000 kilometers from the sea, reaching Northeast Argentina and Eastern Paraguay.
