Identifying Marine Key Biodiversity Areas In The Greater Caribbean Region, Michael S. Harvey Jul 2018

Identifying Marine Key Biodiversity Areas In The Greater Caribbean Region, Michael S. Harvey

Biological Sciences Theses & Dissertations

Anthropocene biodiversity extinction rates are increasing, suggesting a possible sixth global mass extinction event. Biological conservation planners are consequently seeking ways to more effectively protect species at national, regional and global scales. In 2010, the Convention on Biological Diversity (CBD) issued a number of conservation goals (Aichi Targets), including the establishment of protected areas (PA) in terrestrial, freshwater and marine areas of eminent conservation concern by 2020 to reduce and eventually eliminate species’ extinctions, as well as preserve hotspots of biodiversity and dynamic ecosystems. While well-established, adequately enforced PAs increase the likelihood of preserving species and habitats most at risk …

The protection of biodiversity is one of the most important goals in terrestrial and marine conservation. Marine conservation approaches have traditionally followed the example of terrestrial initiatives. However, patterns, processes, habitats, and threats differ greatly between the 2 systems - and even within the marine environment. As a result, there is still a lack of congruence as to how to best identify and prioritize conservation approaches moving from the static terrestrial and nearshore realm into a more fluid, 3-dimensional pelagic realm. To address this problem, we investigate how the conservation science literature has been used to inform and guide management …

Plant and animal populations are frequently found in habitats where the environmental conditions are considered extreme or challenging for life form to exist. These conditions may be classified as either: (1) Supreme: a situation characteristic of degradation conditions where only a few species live under stress, and (2) Extra-ordinary: habitats that provide high biodiversity that are under stress conditions. Due to the differences in what we consider extreme conditions, it is necessary to distinguish between these two categories, because they are not comparable. Our presentation will include examples of these two extreme environmental categories.
