than previously seen. Among the many threats to biodiversity; the destruction of habitats, population growth, pollution, invasive species and overexploitation, climate change is having an adverse effect on biodiversity. The link between biodiversity and climate change has been established for quite some time now. Ecosystems are already showing negative impacts under current levels of climate change. This essay will argue that climate change is a huge
as this will help assessing the risk of a particular species invading successfully, which is covered in chapter 5. The various options of detecting, controlling and eradicating biological invasions is detailed in chapter 6. Chapter 7 concludes this essay. Reptiles, including the dinosaurs that dominated terrestrial life for millions of years, are well known throughout the world. Far from primitive, reptiles have adapted physiologically to a huge range of habitats and come in all shapes and sizes (Pincheira-Donoso
In the last decade or so a host of scientific essays and books have questioned the efficacy of selection and mutation as a mechanism for generating morphological novelty, as even a brief literature survey will establish. Thomson (1992:107) expressed doubt that large-scale morphological changes could accumulate via minor phenotypic changes at the population genetic level. Miklos (1993:29) argued that neo-Darwinism fails to provide a mechanism that can
