Mobilising biodiversity data gathered during environmental impact assessments in South Africa
… study is to identify the barriers to sharing data on species of conservation concern (SCC) in South Africa that are collected during environmental impacts assessments (EIAs) and to propose potential solutions to overcome these barriers. This was done by i) reviewing literature related to this …

In support of natural history digitization: assistive tools for the mobilization of biodiversity data
Much of the primary biodiversity data supporting biology and environmental science are preserved in natural history collections (NHCs). Recently, these collections began to make those data digitally available through online portals thereby improving their accessibility and usability. The processes …

Democratizing plant biodiversity data with coefficients of conservatism for the vascular flora of Tennessee and Kentucky
… flora while utilizing as much pre-existing data as possible. Overall, c-values were successfully applied to 97% of TNKY’s flora (3,295 species). The c-values were then used to create educational modules to democratize biodiversity data. These were made publicly available and sent to nearby …

Building biodiversity data infrastructure for science and decision-making: information needs and information-seeking patterns in South Africa
Biodiversity information is critical to inform science-based policy development as well as to support responsible and accountable land-use planning and decision-making practices. The uptake of available information for these uses is, however, not yet quantified or understood. Here, the extent to …

Biodiversity Assessment: moving towards an evidence-based index for biodiversity offsetting
Biodiversity offsetting is a mechanism for providing physical compensation to redress losses to species and habitats caused by development projects. As offsetting becomes more widespread, so has the evolution and development of frameworks, tools and methodological approaches for assessing …

Antarctic biodiversity surveys using high throughput sequencing: understanding landscape and communities of the Prince Charles Mountains.
… of baseline information on terrestrial Antarctic biodiversity currently impairs efforts to conserve the unique but still largely unknown Antarctic biota. In this thesis I apply metagenetic high throughput sequencing (MHTS) methods to address the deficiency of biological information from remote …

Research data sharing, reuse, and metrics: adoption and challenges across disciplines and repositories
Data sharing is widely believed to be beneficial to science and is now supported by digitization and new online infrastructures for sharing datasets. Nevertheless, differences in research cultures and the sporadic development of data repositories, support services, guidelines, and policies have …

Bee diversity in Angola and community change along an altitudinal gradient at Serra da Chela (Bruco)
… altitudinal gradient (760-1651 m.a.s.l) in the biodiversity rich and critically endangered Angolan escarpment. Pan traps, malaise traps and sweep netting were used at twelve sampling points, with an average of 70 m difference in altitude between points. Sweep netting proved to be the most …

Landscape scale measurement and monitoring of biodiversity in the Australian rangelands
It is becoming increasingly important to monitor biodiversity in the extensive Australian rangelands; currently however, there is no method capable of achieving this goal. There are two potential sources of relevant data that cover the Australian rangelands, and from which measures of biodiversity …
