Corticolous Lichen Diversity on Trees in Urban and Suburban Settings in New Amsterdam, Berbice, Guyana | Chapter 3 | Advanced Research in Biological Science Vol. 1

 Given the insufficiency of information on corticolous lichens in city and suburban areas in Guyana, this study was conducted to label, document and compare corticolous lichen variety on the barks of trees in city and suburban surroundings in New Amsterdam, Guyana. Within each of four study sites a 50m by 20m plot was delineated and healthful mature trees were sampled for the occupancy of corticolous lichens. Forty-one athletic trees from five species were intentional using (10cm by 50cm) graduated system quadrats on the tree core (N, S, E, W) at 150cm height. This study written 14978 individual lichens belonging to 10 classifications, 13 genera and 18 class. Species richness, smoothness and diversity of corticolous lichens communities were driven and Shannon Diversity Index, Simpson’s Diversity Index, Pielou’s Index, Menhinick’s Index and Whittaker’s diversity index were secondhand as the basis for equating lichen difference. The results revealed that the city sites studied were more various and had a higher variety richness and species smoothness than the suburban sites. The overall variety (0.8902) of New Amsterdam was indicative of a very various lichen society. Pairwise comparison of Whittaker’s suspect diversity index for all four sites was 0.5. Menhinick’s Index for copiousness for New Amsterdam was 0.1471. Cladonia parasitica, Hypotrachyna laevigata and Usnea cornuta were restricted to Swietenia mahagoni trunks and Dirinaria applanate was restricted to Cocos nucifera. Corticolous flowerless plant diversity arose to have been affected by the difference of host trees because the species copiousness of corticolous lichens decreased as host forest specificity decreased.
