Ecology

"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".

Domaine benthique marin

♦ Fraction de la biosphère, extrêmement mince, liée intimement au fond des mers et des océans. Il s’étend de la ligne de rivages jusqu’aux plus grandes profondeurs. Trois grandes zones bathymétriques se succèdent ainsi du continent vers le large :

le plateau continental (0-200 mètres, avec la présence d’un estran ou zone intertidale ou de balancement des marées dans les mers à marée) ;

  • le talus continental (zone de rupture de pente de 200-2.000mètres ;
  • les fonds bathyaux-abyssaux au-delà de 2.000 mètres.

On distingue le système phytal (où l’existence d’organismes photosynthétiques est possible), et un système aphytal où il n’y a plus assez de lumière pour assurer la photosynthèse.

♦ Équivalent étranger : Marine benthic realm.
