Project Details

Title: 'The Diversity and Ecophysiology of Bryophytes as Indicators of Hydrology in Trinidad and Tobago'

Summary: Bryophytes are known to exhibit high levels of diversity and occupy a large variety of habitats in tropical forests. They are an important component of forest ecosystems and are a notable feature of the epiphytic community. In Trinidad and Tobago, as plant group, they have not been as well studied as their vascular relatives. The liverworts in particular are also underrepresented in the local herbarium collections. The distribution patterns of stable isotopes, abundance and diversity of epiphytic bryophytes have been shown to correlate with altitudinal variation on the continental mainland. The current research investigates these distribution patterns and diversity of bryophytes on an island scale across the Northern Range of Trinidad and Main Ridge of Tobago. Specific objectives include the estimation of the species richness and diversity of bryophytes and identification of spatial and seasonal patterns in oxygen and carbon stable isotopes in rainfall, atmospheric water vapour and tissue (water and organics) of bryophytes in response to altitudinal variation.
