Glossary

"Using the right word, the right idea, the right concept, with the most commonly accepted definition, or even better, with the best accepted and understood definition, can sometimes be a feat...”

Patrick Triplet

> With this quote, we wish to pay tribute to the colosal work of this biologist, and doctor of ecology whose great oeuvre, Dictionnaire encyclopédique de la diversité biologique et de la conservation de la nature (The Encyclopaedic Dictionary of Biological Diversity and Nature Conservation) ─ compiled over the course of more than ten years ─ is the basis of many of the definitions found in this glossary. Indeed, it is by using a language with precise words and clearly defined concepts that everyone and anyone can approach and understand fields of study that may not necessarily be within their own expertise.

This glossary of over 6,000 definitions, written in French with corresponding English translations, is here to help you. It covers the complementary fields of Geography, Ecology, and Economics, without forgetting a small detour into the world of Finance, which of course regulates a large part of our existence.

Travelling from one definition to another, this glossary invites you to explore the rich world of conservation and to understand its mechanisms and challenges.

We wish you all : "Happy reading and a safe journey through our world".

Étage médiolittoral

♦ Correspond à la zone de l'estran située entre le niveau moyen des hautes mers de vives-eaux et celui des basses mers de mortes-eaux. Ces limites incluent la majeure partie de la zone de balancement des marées. Sur des fonds durs, l'étage médiolittoral est principalement marqué par la présence d'algues brunes de type Fucus. Dans cet étage, les sédiments ne retiennent à basse mer que l’eau de rétention, l’eau de saturation oscillant avec la marée. Cette possibilité de retenir le film d’eau autour des grains de sable est variable selon la nature du sédiment et selon la pente de la plage. Les organismes dans cet étage doivent pouvoir supporter de fortes fluctuations de salinité, car c’est le facteur maître dans cet étage.
♦ Équivalent étranger : Mediolittoral zone.
