Module description

This module will introduce some key topics in marine biodiversity including methods of assessing marine biodiversity, distribution of species in space and time, maintenance of marine biodiversity, and regulation of populations.

The module also introduces key marine taxa. Selected examples will focus on adaptations in planktonic organisms, biodiversity hot-spots such as coral reefs and explore disturbance and succession. The self learning component investigates the utility of nucleotide databases for reference RNA and environmental metagenomes in biodiversity research. Two practicals will examine the biodiversity in muddy and sandy shores, and the morphological and genetic diversity in marine amphipods.

Module aims

The aim of this module is to introduce key topics in marine biodiversity

Module learning outcomes

On successful completion of the module, students will be able to:

1. describe the key methods in assessing marine biodiversity
2. explain the patterns of diversity in marine systems, considering gradients of diversity on global scales, with depth in the oceans and through evolutionary time;
3. explain the mechanisms that generate and maintain patterns of diversity
4. show competence in retrieving relevant information from diverse sources, interpreting scientific data and demonstrate ability to organize and execute a self-learning task;
5. demonstrate competence in written communication and information retrieval;
6. demonstrate competence in data presentation, analysis and interpretation, numeracy, information retrieval and written communication.

Module information

No additional information available.

Learning and teaching methods

20 x 1 hour lectures (including 1 on directed learning material and 1 or more covering DAI material), plus 1 revision class before summer exam. There will be a total of 2 practicals: the first will run over two days (4 + 3 hours), the second is scheduled to run for 3 hours.
