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: Wild chimpanzees have demonstrated impressive long-term memory by regularly revisiting hidden underground army ant nests over multiple years.
📈 One key stat: Approximately 67.6% of identified adult chimpanzees revisited at least one ant nest during a five-year study, highlighting their capability for spatial memory.
💬 One key quote: “An adult female chimpanzee named Hiila revisited one of the monitored army ant nests 25 days across 5 years.”
1️⃣ The big picture: Chimpanzees are known for their intelligence, but recent findings reveal just how sophisticated their memory can be. In a study conducted over five years, researchers observed wild chimpanzees in Dindefelo, Senegal, and found that they could recall the locations of concealed army ant nests. This behavior not only demonstrates their ability to remember specific locations but also suggests a complex understanding of foraging strategies. By revisiting these nests, the chimps optimize their foraging efforts and secure access to a valuable food source.
2️⃣ Why is this good news: This discovery showcases the remarkable cognitive abilities of chimpanzees, reinforcing their status as one of the most intelligent species on the planet. Understanding how these animals use their memories can provide insights into their survival strategies and social behaviors in their natural habitats. The findings also highlight the need for conservation efforts as these habitats face threats from deforestation and climate change, reminding us of the importance of protecting these incredible creatures and their environments.
3️⃣ What’s next: Further research will focus on exploring the nuances of chimpanzee memory and foraging strategies across different habitats. Scientists plan to investigate how environmental factors influence the availability of resources and the cognitive demands placed on chimpanzees. These studies could also pave the way for examining similarities in memory and foraging techniques among other primates, potentially enhancing our understanding of animal cognition as a whole.
