Extreme Marine Habitats
Run by School of Ocean Sciences
20 Credits or 10 ECTS Credits
Organiser: Dr Andy Davies
Overall aims and purpose
The vast array of habitats found within the Earth's oceans is central to a wide diversity of life. Amongst them are deep-sea habitats thousands of meters from the surface, hydrothermal vents at temperatures of hundreds of degrees centigrade, wave swept rocky shores or challenging polar conditions where temperatures plummet. In this module, we will focus on a range of different extreme marine habitats, introducing the physiologically challenging conditions that determine the abundance and geographical distribution of marine organisms.
This module will: - Explain why no extreme habitat is extreme to the organisms that live there. - Introduce a range of extreme habitats including the deep-sea, hydrothermal vents, cold-seeps and wave-swept rocky shores. - Examine the physiological and morphological adaptations that organisms have undergone to fully exploit each extreme habitat.
This module will consider the environmental and physiological factors that determine the distribution and abundance of marine organisms in a range of extreme environments. The environments covered are: hydrothermal vents, deep-sea habitats, sea ice and cold hydrocarbon seeps. How the organisms have managed to adapt physiologically within these environments will be discussed and students will be shown the similarities and differences between these ecosystems and those in less extreme environments
Knowledge and basic understanding reliant entirely on the taught programme. Basic understanding of subject-specific theories, concepts and principles. Presents a competent overview of an extreme habitat in their assessment.
Wider knowledge and moderate understanding based on the taught programme, but with evidence of enquiry beyond that. Understanding of subject-specific theories, concepts and principles and some understanding of specialist areas. Presents a detailed, well researched and illustrated assessment showing clear understanding of the topic and questions posed
A very wide knowledge base extending well beyond the directly taught programme showing an in-depth understanding of the concepts presented. Thorough understanding of subject-specific theories, concepts and principles and in-depth understanding of more specialist areas. Presents an insightful, carefully argued, illustrated assessment showing clear evidence of independent thought.
The environmental and biological factors controlling the distribution patterns of organisms in the extreme environments of the oceans.
How organisms are able to cope with the extreme physiological demands of their environment.
The concept of extreme environments and the fact that they are not extreme for the organisms that inhabit them.
