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".

Indice des plantes immergées dans les lacs

♦ Indice qui utilise les observations de plantes aquatiques recueillies par des plongeurs qualifiés, des plongeurs autonomes et des plongeurs en apnée, à l'aide de méthodes normalisées (de Winton et al, 2012). Les informations sur la structure et la composition des plantes immergées sont utilisées pour calculer trois indices :

Les indices de condition indigène et les indices d'impact invasif sont utilisés ensemble pour générer l'indice LakeSPI, qui fournit un indicateur global de la condition écologique d'un lac. Un indice élevé est souhaitable :

  •  0 à 20%     >> Conditions écologiques médiocres
  • 20 à 50%    >> Conditions écologiques modérées
  • 50 à 75%    >> Conditions écologiques élevées
  • 75 à 100%  >> Conditions écologiques excellentes.
