摘要: Fragmentation et insectes : theorie application aux pelouses calcaires. La perte d’habitat constitue la plus importante menace a long terme pour survie des especes decoule de trois processus principaux : destruction l’habitat, l’augmentation fragmentation l’alteration qualite l’habitat. qui se traduit par creation plusieurs petits fragments spatialement isoles partir d’un seul fragment continu, consequence diminution l’abondance, densite diversite specifiques ; effets lisiere l’isolement restants. Quelques resultats preliminaires sur les communautes (diversite abondance specifiques) papillons jour calcaires vallee du Viroin (Belgique) seront presentes.
