Marine ecosystem classification and conservation targets within the Agulhas ecoregion, South Africa
… and mapping, and (ii) to determine the conservation targets for selected national marine ecosystem types to inform improved management of the marine environment, through Marine Spatial Planning processes. Visual surveys of the seabed were conducted to quantify epifauna during the ACEP …

Incorporating costs and processes into systematic conservation planning in a biodiversity hotspot
… to stem the rapid destruction of biodiversity, conservationists must set clear priorities for action. Systematic Conservation Planning (SCP) is an approach that uses spatially explicit data to identify areas that meet conservation targets efficiently, usually focusing on species’ representation. …

Variation In Habitat Thresholds: An Analysis Of Minimum Habitat Requirements Of North American Breeding Birds
… `extinction thresholds' could be translated to conservation targets, under the condition that we can derive generalities. I investigated the level of variation in landscape-level habitat thresholds for a suite of North American, forest-associated, breeding birds. Records from Breeding Bird …

The global network of marine protected areas: developing baselines and identifying priorities
Recently adopted global marine protection targets aim to protect 10-30% of marine habitats within the next 3 to 5 years. However, these targets were adopted without prior assessment of their attainability. Moreover, our ability to monitor progress towards such targets has been constrained by a lack …

Adapting Protected Area Networks to the Impacts of Climate Change: Potential Options for the Sub-Saharan Africa Important Bird Area (IBA) Network
… climate change represents a major challenge to conservation over the 21st Century and beyond. Currently, conservation is largely reliant upon static Protected Areas (PAs) to conserve uncommon species. However, evidence from past climate change events suggests that species distributions are …

The application of systematic conservation planning in the succulent Karoo biome of South Africa
Systematic conservation planning is about making spatially explicit decisions regarding the use of land, based on the observed or expected biodiversity present at a site and the potential for that same site to support alternative /and-uses that are not compatible with the persistence of …

A systematic conservation assessment of habitat transformation and degradation in the Little Karoo, South Africa
… Endangered, Vulnerable and Least Threatened). Conservation targets were modified according to the number of species and degree of endemism within each vegetation unit. Finally, using long-term climate and agricultural census records, the historic causes of degradation in the region were also …

Housing, health and affordable warmth: an investigation into the link between fuel poverty risk and the health of older people
… were peripheral to environmentally driven energy conservation targets, designed primarily to reduce carbon dioxide emissions to meet national climate change commitments. However, these targets can militate against solving immediate needs of the fuel poor. Those who cannot afford sufficient fuel …

The influence of location on the structure and functioning of private land conservation networks in the Western Cape province of South Africa
… areas are an important tool for biodiversity conservation. Statutory protected areas are, however, perceived to currently be insufficient in extent and functioning for achieving conservation goals. Conservation action on privately owned land plays an increasingly vital role in expanding the …

Applications of the IUCN Red List in evaluating global extinction risk of timber tree species.
… for rapid species assessment in order to inform conservation actions. However, the use of ‘big data’ is coming to the fore in ecological research, and offers a valuable chance to meet international assessment targets such as those of The Global Strategy for Plant Conservation (GSPC), which call …

Towards ecological restoration strategies for Peninsula Shale Renosterveld: testing the effects of disturbance-intervention treatments on seed germination on Devil's Peak, Cape Town
… Shale Renosterveld is essential to redress its conservation target shortfall. The ecosystem is Critically Endangered and, along with all other renosterveld types in the Cape lowlands, declared 'totally irreplaceable'. Further to conserving all extant remnants, ecological restoration is required …

Investigation of a Novel MPCM-S Based PV/T System
In order to meet energy conservation targets and minimize global warming effects, this research is aimed to rise the efficiency of the PV/T system. This research investigates the usage of microencapsulated phase change slurry (MPCM-S) to replace conventional cooling fluids such as water. The phase …

A Genomics Approach to Conservation, Systematics, and Phylogeography to Understand Two Lineages of Lamiales
… and diversification, and (5) addresses conservation concerns and prospects in a phylogenetic context. Phylogenetic analyses indicate that Barlerieae is monophyletic (given our sampling) and resolve relationships among all thirteen currently recognized genera in Barlerieae. Strong support …

Protecting the deep: The combined impact of climate change and bottom trawling on VME indicator taxa in New Zealand and implications for management
… Economic Zone and explores implications for conservation. The research explores (i) climate change impacts and potential refugia, (ii) the added pressure of bottom trawling, and (iii) management strategies with policymakers and fishery regulators to fast-track spatial protection measures in …

Marine stressor and receptor interactions: A new approach to incorporate multiple stressor impacts into marine spatial management
… stressors increases the risk of focussing conservation efforts on areas that could become ecologically diminished in the future. To ensure that global biodiversity conservation targets are upheld under ongoing anthropogenic conditions, practitioners must identify robust and ecologically …
