About the Book

La diversité des lichens est un indicateur utile pour évaluer la santé de l'environnement dans lequel ils se trouvent. La déforestation et l'évolution de l'utilisation des sols modifient la structure des populations et les conditions de l'écosystème pour la plupart des biotes. L'identification par des tests morphologiques et chimiques a révélé un total de 89 espèces, dans 27 familles, et 22 de ces espèces étaient spécifiques à un site. Les Parmeliaceae et les espèces d'Usnea, d'Heterodermia et de Dirinaria applanata dominent la zone. Les espèces identifiées se présentent sous six formes de croissance et ont été recensées sur neuf types de substrat. Les lichens foliacés et corticoles étaient les plus représentés. Le plus grand nombre d'espèces (79) avec des valeurs de diversité et de richesse des espèces de 5,70 et 29,7% respectivement et 17 espèces restreintes ont été enregistrées dans le site le plus vierge à des altitudes >1000 m. Les clés d'identification produites dans l'étude fournissent un guide instructif sur les lichens du Mont Cameroun. Les descriptions détaillées de 89 espèces contribuent de manière significative aux connaissances sur le terrain. Cette étude fournit un large spectre d'espèces de lichens qui informent sur les changements dans notre environnement, avec des implications pour la gestion et la conservation des paysages forestiers dans le monde entier.
