Diversity and composition of the epiphytic flora in an urban agglomeration: The case of city of Douala, Cameroon
Epiphytes constitute an element of climate regulation in the tropical zone. In Cameroon, the decline in forest area of about 220,000 ha, partly due to urbanization, has been observed. The research aim was to characterize the epiphytic flora of the urban ecosystem of Douala. Four zones represented by nine neighbourhoods were chosen for the surveys. Four transects of a maximum distance of 500 m were scanned on each...

Effect of IAA on spore germination and gametophyte development in Ceratopteris thalictroides (l.) brongn. from Sitamata Wild Life Sanctuary, Rajasthan
The effect of different concentrations of Indole acetic acid (IAA) on spore germination and gametophyte development of Ceratopteris thalictroides, a leptosporangiate fern of the family Pteridaceae found at the marshy places near Sitamata sanctuary in Rajasthan, was observed. The highest spore germination percentage was recorded in the 2 to 6 ppm concentration range of IAA, with minimum in the 10 ppm concentration. The...

Effects of land use on floristic composition and diversity of woody vegetation in the commune of Enampore, Senegal
The diversity of woody vegetation is threatened by intensified land use and soil chemistry. However, the effects of land use and soil chemistry on woody vegetation are not well known. The objective of this study was to determine the influence of land use classes (upland, uncultivated lowland, cultivated lowland, and tans) on the diversity and structure of woody vegetation in the commune of Enampore. To do this, an...
