#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.
