Using Financial Theory to Protect Puerto Rico’s Tree Frog
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists applied modern portfolio theory from finance to protect endangered species like Puerto Rico’s smallest tree frog by diversifying conservation investments across different habitats to maximize survival chances.
📈 One key stat: Northern Puerto Rico has seen sea level rise rates increase sixfold from 2.08mm to 12.12mm per year between 2010-2016, putting coastal wetland habitats at immediate risk.
💬 One key quote: “Diversification of investments is kind of a magic bullet for stability under future market uncertainty,” says Mitch Eaton, lead author of the study and research ecologist at the Southeast Climate Adaptation Science Center.
1️⃣ The big picture: Scientists have found an innovative way to protect endangered species by applying economic principles to conservation efforts. Using modern portfolio theory, commonly used in finance, researchers modeled different scenarios to safeguard Puerto Rico’s smallest tree frog, the coquí llanero, which lives only in three small coastal wetland areas. The approach focuses on diversifying conservation investments across different habitats to minimize extinction risks, similar to how investors spread financial risk across various assets. This method helps conservation managers make strategic decisions about habitat protection and species relocation while dealing with challenges like climate change and limited resources.
2️⃣ Why is this good news: This new approach gives conservation managers a practical framework to make better decisions about protecting endangered species. By treating conservation like an investment portfolio, they can strategically select and protect different types of habitats that help species survive under various future scenarios. The method can be scaled up to protect multiple species simultaneously and enhance overall ecosystem resilience. The research also identified promising new habitats on Puerto Rico’s eastern coast that could help expand the geographic range for endangered species like the coquí llanero.
3️⃣ What’s next: Scientists need to continue researching and refining this portfolio approach while collaborating with conservationists and policymakers to implement these strategies effectively. Securing adequate funding and public support for conservation initiatives remains crucial. The focus now shifts to practical application – identifying and protecting new habitat refuges, planning species relocations when needed, and monitoring the success of these diversified conservation strategies.
