Freshwater Ecosystems & their Goods & Services 1 (10 credits)
Run by School of Natural Sciences
10.000 Credits or 5.000 ECTS Credits
Organiser: Dr Nathalie Fenner
Overall aims and purpose
In spite of the relatively small percentage of the globe which they cover, freshwater ecosystems have huge significance for both humans and other organisms, even those in marine and terrestrial systems. This module introduces students to the diversity of freshwater habitats, from streams and rivers to ponds, lakes and wetlands. It will consider the evolution of these systems, the chemical and physical factors of importance and how these affect the biological communities within and beyond. Relationships between the different components of freshwater ecosystems will be explored and how they relate to ecosystem goods and services (EG&S). Different methods of classifying water bodies will be examined and the concept of payment for EG&S. Throughout our evolution, humans have had a close relationship with freshwater ecosystems and we will consider the effects of human activity over time and contemporary issues in the field. We will look at fisheries and fish stock assessment in fresh waters, at pollution, habitat disturbance and destruction, and also consider the creation of fresh water bodies. We will explore the consequences of human impacts on fresh waters for biodiversity, the environment and the future. We will consider some of the conflicts between exploitation of resources by humans and conservation. We will examine different approaches to conservation in freshwater systems, and consider the context in which decisions must be made. This module is designed to familiarise students with the knowledge and skills required for research into, and management of, freshwater ecosystems, for which there is a particular demand in the region. It will draw heavily on the expertise of professionals from not only within the University but from outside agencies (e.g. Natural Resources Wales (NRW), local consultancies) for design and delivery of the module.

Demonstrate the skills necessary for self-managed and lifelong learning (undertaking directed reading, time management, working to a deadline)
Describe the main processes and mechanisms which lead to the formation of fresh water ecosystems.
Distinguish between different freshwater systems and describe their main features.
Understand the relationships between chemical, physical and biological components of these systems.
Appreciate how the ecological characteristics of particular habitats determines their management.
Understand and compare the scientific methods employed to study freshwater ecosystems.
Demonstrate knowledge of actual and potential human impacts on freshwaters and their EG&S, but understand the available options for conservation and management of fresh water ecosystems and the context in which any decisions must be made.
Demonstrate the ability to think critically and apply a problem-solving approach (identifying hypotheses, considering options, drawing conclusions from data and considering implications of these conclusions) when presented with a hypothetical or real scenario based on a freshwater ecosystem.
|EXAM||End Module Exam||
Open book exam where students write an essay (1000 words excluding references and figures) answering a question from a list of choices. The topics from which the questions will be formulated will be know in advance, but not the actual essay question. The questions will be released on line and available for 24h.
Teaching and Learning Strategy
Approx. 15hr of lectures (depending on guest lecturer availability etc.), including typically case studies & guest lectures relating to current research and management in freshwater ecosystems, plus interactive sessions where students participate in full class discussion, allowing feedback on their understanding of the material covered to date. More specifically indicative content would be: a. Case study material relating to current research and management in freshwater ecosystems, integrating theory and practice. b. external guest lectures from Natural Resources Wales (NRW) & APEM Ltd c. 1 x 2 h revision & feedback session to prepare for exams.
A virtual or in situ field trip and or case study (approx. day or half day) where students will for example experience conservation measures on the ground and/or contemporary management methodology. Depends on site availability and weather etc.
Private study should supplement all teaching. Online support for the module will be provided via Blackboard, which will supply reference material, links to online resources, guidelines for completing assessments etc. Students will have access to external resources from, for example NRW and consultancy firms (e.g. APEM Ltd) linking content to employability.
