So… Which method to chose?
0 guenee 0 Starts on: 2017.12.22By now, if you’ve read my blogpost and followed my journey, you’ve gained much knowledge on earthworms and how to sampls them. You also know that AITC method is more efficient than the octet one. What you might not know is that sometimes, a specific method really is the only way. To help you decide […]

Overview of my internship: “Comparison of the efficiency of two earthworm sampling methods in peri urban areas”
0 guenee 0 Starts on: 2017.12.22During my internship, I had to compare two earthworm sampling methods: the Allyl IsoThioCyanate method (a behavioral, chemical method) and the octet method (a behavioral, electrical method). To know more about these methods, you can read my “My sampling methods” blogpost. These sampling were performed in 18 peri urban sites around the Plateau de Saclay. […]

My sampling methods
0 guenee 0 Starts on: 2017.12.22There are a lot of earthworm sampling methods that exist. Some are passive (hand-sorting for example) while others are behavioral [1]. During my internship, I compared two sampling methods: an electrical one (the octet method) and a chemical one (the AITC -allyl isothiocyanate). Both of these methods are behavioral method, however the AITC method […]

From Darwin to this day
0 guenee 0 Starts on: 2017.12.14Earthworms are great indicators to study the impacts of land use and management on ecosystem, as they respect the four criteria for bio-indicators: reproducibility, specificity, reliability and relevance [1]. In 1984, they became standard organisms when studying ecotoxicology within the European Union [2 – 3]. They are specifically known to be good indicators of soil […]

Knowing your ecological groups
0 guenee 0 Starts on: 2017.12.14In France alone, there is over 100 species of earthworm [1]. But before we jump in how to differentiate them, let’s focus a bit on their ecological groups. There are 3 main ecological groups : the epigeics (Greek epigeios, upon earth), endogeics (Greek endogeios, within earth) and the anecics (Greek anecic, out of earth”). Each […]
