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?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. 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?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. 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.

Stay impactful,

📰 The quick summary: Research from the University of Lincoln reveals that red-footed tortoises experience lasting mood states similar to mammals and birds, challenging traditional beliefs about reptile emotions and providing valuable insights for improving captive animal welfare.
📈 One key stat: Tortoises living in enriched environments were more likely to interpret ambiguous cues positively, indicating a more optimistic state of mind that could significantly improve animal welfare standards.
💬 One key quote: “This is an exciting finding that represents a significant shift in our understanding of what reptiles can experience, with important implications for how we care for these animals in captivity and interact with them in the wild,” said Oliver Burman, Professor of Animal Behavior and Welfare at the University of Lincoln.

1️⃣ The big picture: Scientists at the University of Lincoln have discovered that red-footed tortoises can experience long-term mood states, similar to those observed in mammals and birds. The research team applied cognitive bias tests designed for humans to 15 tortoises to measure how they interpret ambiguous situations. Their findings show that tortoises in enriched environments displayed more optimistic responses and fewer signs of anxiety. This breakthrough challenges long-held beliefs that reptiles have limited emotional capacity and provides new evidence of sentience in animals that diverged from mammals hundreds of millions of years ago.

2️⃣ Why is this good news: This discovery has far-reaching implications for animal welfare laws and practices, especially as reptiles become increasingly popular as pets. Understanding that tortoises can experience moods helps create more appropriate care guidelines that consider their emotional well-being, not just physical needs. The findings align with the UK’s Animal Welfare Act, which recognizes animal sentience as a basis for protection. More broadly, this research suggests that emotional experiences may be more widespread throughout the animal kingdom than previously thought, potentially transforming how humans interact with and care for various species across evolutionary lines.

3️⃣ What’s next: Scientists will likely expand research to other reptile species to determine how widespread these emotional capabilities are. Animal welfare organizations can use these findings to develop enhanced guidelines for reptile care in captivity. Conservation efforts may also benefit from better understanding tortoise emotional needs, potentially improving breeding programs and habitat protection initiatives.
