Teacher essay summary
Overall this is an excellent essay, showing a high level of comprehension. It has a clear structure, covers not just the definition of hotspots, but problems with that definition and why they might arise. It is largely articulate and demonstrates a wide reading base. To make it even better, the author should concentrate on her writing style. At times she allows her sentences to get very long, and loses coherency as a result. She is also overly dependent on a few sources that she unnecessarily quotes rather than paraphrasing in her own words. In a few places the writing is repetitive or convoluted, and as a result the essay is very long, despite lacking detail in a few key areas. At my (Russell group) university, this would score 5 stars.

"I have never experienced such intense delight... such a plenitude of forms, colours, behaviours-such a magnitude of Life! What explains the riot?"
- Darwin (1851)
"The current massive degradation of habitat and extinction of species is taking place on a catastrophically short timescale, and their effects will fundamentally reset the future evolution of the planet's biota."
- Novacek & Cleland (2001)
Biodiversity may be regarded as 'the number, variety and variability of living organisms' (MacDonald, 2003: 406). Whilst global variation in biological diversity has long been a source of fascination, it has recently been the basis for increasing concern (Tilman, 2000). Awareness of the extent and rate of the current biodiversity crisis (or the 'sixth extinction', as termed by Leakey & Lewin, 1996) has led to a significant re-assessment of the role of biodiversity in ecosystem functioning and the scope for policy intervention to enable its preservation, exemplified by the international ratification of the Convention on Biodiversity in 1992. The identification and analysis of spatial patterns of biodiversity has been central to conservation goals of maximum preservation at the least
