Genetics and elephant conservation

Article Abstract:

Genetic diversity plays an important role in ensuring a species' survival, since it gives them the ability to adapt to changes in environment. In a study evaluating the effectiveness of genetic techniques in regulating the ivory trade, scientists examined mitochondrial deoxyribonucleic acid (DNA) variants to determine African elephants' geographic variation and population subdivision. In another study, DNA fingerprinting was applied to establish Asian elephants' paternity and degree of relatedness. Results obtained by these studies underscore the importance of genetics in the formulation of strategies for the protection of endangered species.

Remote sensing, geographic data and the conservation of biological resources

Article Abstract:

The use of remote sensing technology has become more necessary in view of the global changes caused by human activities. This technology, which relies mainly on satellite images and aerial photographs, enables scientists to track the impact of humans on the environment through simultaneous observations of large areas of the earth. The Geographic Access, Image and Analysis software was developed to aid in the analysis and management of data and images provided by remote sensing. It allows the integration of raster and vector data, the creation of thematic mapsand the display of Landsat and SPOT images.

Negotiating for conservation

Article Abstract:

The habitat conservation plan (HCP) is useful for enforcing the Endangered Species Act, ensuring the conservation of wildlife and allowing landowners to maximize their profits from their properties. To ensure the success of an HCP, it should be based on scientific findings, involve long-term monitoring and be flexible depending on conditions. Because these elements are not always present, not all HCP proposals should be approved. The agencies responsible for the negotiation of HCPs are the US Fish and Wildlife Service and the National Marine Fisheries Service.
