• W2113668040 abstract "Globally, invasion of an ecosystem by alien species is acknowledged as one of the major threats to biodiversity. Disturbances that modify ecosystem structure and dynamics have been shown to facilitate invasion success. Increasing population and related changes in land cover determine the amount of disturbances to which an ecosystem is subjected. The aim of this thesis is: (1) to examine changes in population and land cover following malaria eradication in the Terai of Nepal; (2) to investigate factors influencing the presence, abundance and age composition of the invasive species Chromolaena odorata (L.) R. King & H. Robinson in the Shorea forests of the Terai in Nepal; and (3) to provide evidence for the hypothesis that the success of Chromolaena is dependant on the degradation status of the Shorea forests. Land cover and census data were used to estimate changes in population growth and subsequent changes in land cover and population pressure on forest and arable land. Gaussian regression models were employed to examine relationships of Chromolaena cover, biomass and biometric properties to independent variables comprised of understorey light intensity (mj m day), understorey biomass and grazing. Relationships of Chromolaena presence and age composition to independent variables were examined using logistic regression. Human population in the Terai has increased substantially after the initiation of malaria eradication programmes in the early 1950s. Forest cover has declined while arable land area has increased. Human population pressure on forest resources have risen considerably since 1958. Understorey light intensity and understorey biomass differed significantly in grazed and ungrazed areas. Grazing is taken as an indicator of human presence. This suggests that increased human utilization together with grazing has degraded the Shorea forests in terms of forest canopy openness and understorey biomass levels. Chromolaena presence, cover, biomass and biometric traits were significantly related to understorey light intensity and understorey biomass. Grazing exhibited an indirect effect on Chromolaena cover and biomass. Higher values for Chromolaena cover; biomass and biometric properties (height, diameter, number of stems and number of branches) were found in areas with medium understorey light intensity (1.5 – 3 mj m day) and low understorey biomass. The age composition of Chromolaena populations was also significantly related to understorey light intensity and understorey biomass, where the probability to find Chromolaena populations with potential to reproduce was low in environments with low light intensity. Populations that existed in environments characterised by low light intensity (<1.3 mj m day) and high understorey biomass appeared to be small plants that had not matured beyond seedling stage. That these plants would set flower and produce seeds is highly unlikely. Human utilisation of forests in the Terai intensified after the initiation of malaria eradication programmes made the Terai suitable for settlement to people from the Hill and Mountain regions. Human use together with grazing has contributed to bringing about changes in the forest overstorey and understorey by making forest canopies more open and reducing understorey biomass levels. This has helped the successful establishment of Chromolaena, where success is measured in terms of presence, cover, biomass, biometric traits, and age composition." @default.
