#2: Quantifying biodiversity



🌿 Mathematical deciphering of Biodiversity in the Forests of the Azores 📊


In this fascinating exploration, we plunge into the heart of the natively preserved forests of the Azores to unravel the mysteries of biodiversity, armed with sophisticated mathematical techniques.


🔍 Scientific objective :

Our mission: to understand how mathematics can be used to quantify biological diversity in ecosystems. Through a ten-year study, we are examining the structure of arthropod communities in these isolated forests.


📈 Sampling Techniques :

Using strategically placed arthropod traps, we have been collecting seasonal data since 2012. We are exploring the logistical and statistical challenges involved in ensuring the reliability of the results.


📊 Mathematical analysis :

Using methods such as slope estimates and statistical tests, we analyse alpha-diversity (local diversity) and beta-diversity (differences between communities). We decipher temporal and seasonal trends.


🌳 Importance of Species :

We examine the abundance of hyperdominant and rare species, revealing their crucial role in the stability and functionality of the ecosystem.


💡 Interpretation of Results :

Our conclusions are backed up by statistical significance tests, ensuring that our findings are not the result of chance.
