Factors Influencing the Range Shift of Plant Species in Wetlands in Northern Region (Ghana), With a Note on the Fish and Bird Communities

ABSTRACT The study examined the role of anthropogenic disturbances, temperature, precipitation and evapotranspiration in the range shift of aquatic plants, fish and bird communities in six wetlands. It was conducted over a 2-year period. The dominance ratio approach was used to determine the range shift of plants. Ordination techniques were used to determine the influence of environmental factors on biological data-set. Of the 40 species of plants sampled, obligate species constituted 35%, wh...

Intertidal Macro-Algal Diversity and Zonation Patterns of the Eastern and Western Coasts of Ghana

ABSTRACT  Based on abundance and distribution of species along the intertidal continuum from the sublittoral to the supralittoral, rocky shores have been divided into zones globally.  Rocky shore zonation has been assumed to follow broad regional and latitudinal patterns with no attention being paid to smaller scale patterns. The aim of this study is to find out if the global 3-zone division is applicable to Ghanaian shores based on multivariate analysis. Macroalgae which constitute th...
