Assessment of ecosystem integrity of lowland dipterocarp forest ecosystem using remote sensing
Ecosystem Integrity Index (EII) is a concept to determine the quality or the health of an ecosystem. The EII development can assist forest managers and decision makers in the conservation effort and forest management in Malaysia through the development of a simple and easy-to-adopt index. The aim …

A macroinvertebrate bioassessment of two streams on Turnbull National Wildlife Refuge (TNWR)
… Cheney, WA to evaluate the health status and ecosystem integrity of the water bodies. Turnbull National Wildlife Refuge contains over 3,000 acres of wetlands, and provides high quality habitat for migrating and breeding waterfowl. However, these wetlands are impacted by both high nutrient …

Estimating Reservoir Storage Dynamics Using Satellite Remote Sensing and Hypsometric Information
… significantly influences downstream hydrology, ecosystem integrity, and water availability. However, a persistent lack of publicly accessible reservoir operation data, especially in transboundary and developing regions, hampers our understanding of storage dynamics and limits the development of …

Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
… are increasingly important as providers of ecosystem services including habitat for numerous wildlife species. It is crucial to maintain a balance between timber production and conservation of biodiversity on managed landscapes. Salamander populations can play key roles in the function and …

Response of rodents to land use gradients in small-holder farms in Northern Limpopo: implications for ecologically-based rodent management (EBRM)
… dynamics and species composition, but also their ecosystem services and integrity. Understanding how rodents respond to these land use changes (crop, grazing and settlement) will not only improve the implementation of Ecologically Based Rodent Management (EBRM), but might also enable the …

Soil rutting prediction using Random Forest model
… can have profound impacts on forest health and ecosystem integrity, disrupting soil structure, compacting soil layers, and altering drainage patterns. Consequently, soil erosion may occur, leading to the loss of topsoil, nutrient depletion, and reduced soil fertility, ultimately affecting forest …

Site Characterization, Sustainability Evaluation and Life Cycle Emissions Assessment of Underground Coal Gasification
… that UCG can integrate economic activity with ecosystem integrity, respect for the rights of future generations to the use of resources and the attainment of sustainable and equitable social and economic benefits. The important aspects of UCG that need to be considered for its sustainable …

Effects of protected areas and climate change on the occupancy dynamics of common bird species in South Africa
… because they have been shown to drive important ecosystem patterns, and a decline in abundance and diversity of common species can indicate drastic declines in ecosystem integrity. This thesis comprises four data chapters; in the first three I model the occupancy dynamics of 200 common, resident …

The ecological impacts of agrivoltaics in semi-arid grasslands
… meet renewable energy goals without compromising ecosystem integrity. While agrivoltaic systems theoretically enable multifunctional landscapes providing both energy and ecosystem services, comprehensive understanding of their ecological impacts remains limited. I conducted multi-scale assessments …

Valuing ecosystem services in a green economy
SCOPE: Ecosystems are being degraded and destroyed worldwide at a rate unprecedented in human history. Accordingly a great deal of interest is currently being focussed on ecosystems, the role they play in planetary life support, and the need for a market mechanism to conserve these formerly …

The Effect of Select Biological and Environmental Factors on the Horizontal Gene Transfer and Functionality of the TOL Plasmid: A Case Study for Genetic Bioaugmentation
… structure and a long-term instability in ecosystem integrity. Furthermore, the degradative activities of such foreign microbes may be compromised when introduced into an unfamiliar environment during bioaugmentation, thereby resulting in a lower bioremediation potential. </p><p>Horizontal …

The IUCN red list for ecosystems: how does it compare to South Africa's approach to listing threatened ecosystems?
… for Conservation of Nature (IUCN) Red List of Ecosystems (RLE) standards is an important development that has received broad acceptance globally. More than 100 countries across the globe including South Africa and Myanmar have adopted the IUCN RLE standards as their national framework for …
