Delimitation and diversity of the genus Badula Juss. (primulaceae) - rare endemic trees of the Mascarene Archipelago
(Trinity College (Dublin, Ireland). Department of Botany, 2010)The western Indian Ocean Mascarene archipelago is a trio of geologically young volcanic islands that have never been connected to a continent or continental fragments. The islands are biologically diverse, and 72% of the ... -
Assessing soil respiration in the soil profile. A study case of gradient-based CO2 efflux and subsurface production rates using soil diffusion chambers
(Trinity College (Dublin, Ireland). Department of Botany, 2010)The impact of global warming on soil respiration is strongly related to the characteristics of deep-soil carbon and may differ with soil depth. Environmental parameters can affect the rates of soil CO2 respiration not only ... -
Phylogenetic classification of the world's tropical forests
(2018)Identifying and explaining regional differences in tropical forest dynamics, structure, diversity, and composition are critical for anticipating region-specific responses to global environmental change. Floristic classifications ... -
Physiological studies of salt tolerance in Plantago maritima (L.)
(Trinity College (Dublin, Ireland). Department of Botany, 2001)The studies described in this thesis were concerned with evaluating the salt tolerance mechanisms of Plantago maritima (L.). This species, a perennial herb, is found growing in various habitats including saline coastal ... -

The flora and vegetation of Pitcairn Island : its phytogeography and conservation
(Trinity College (Dublin, Ireland). Department of Botany, 2001)Good decisions cannot be made about the conservation of nature if we do not know what it is, where it is, and in what abundance. The aim of this thesis was to provide an integrated approach to the conservation of Pitcairn ... -
The exploitation of soil organic phosphate by grassland plants
(Trinity College (Dublin, Ireland). Department of Botany, 2002)This study was concerned with the availability of soil organic phosphate (Po) to plants. To address this issue semi-natural Irish grassland soils and plants were used. Greenhouse experiments were carried out in which soil ... -
