Ecosystems in a Changing Global Environment

Human impacts on the world¿s ecosystems are profound and without precedent in Earth's history. The urgent need to understand the impacts of overexploitation, land-use change and anthropogenic climate change has meant that ecosystem science has become one of the most important biological disciplines. This module will introduce students to the fundamental principles of ecosystem science by exploring human impacts on key marine and terrestrial ecosystems and their feedbacks on global climate. In doing so, it will cover the interacting roles of (1) climatic tolerance, trophic interactions, carbon sequestration and fire on land, and (2) biodiversity, energy, nutrients and extinction in the sea.

10 credits

Plant Habitat and Distribution

This course will: provide experience of work in the laboratory and in the field; provide an introduction to the techniques employed in the study of plants in relation to their habitats and the vegetation in which they occur; develop skills in record keeping, observation, sampling, identification, problem solving, task-oriented team work, data interpretation, communication and the application of biological principles; and help develop an understanding of aspects of the plant environment and the importance of environmental variables and plant traits in controlling species distributions. This course consists of an integrated series of 12 sessions which include lectures and practical work relevant to understanding controls on plant distributions and community composition. The course includes 2 field excursions (soil and vegetation sampling), 7 practical classes (soil chemical analysis, experimental ecology, vegetation data analysis and vegetation processes), 8 lectures and 1 session for synthesis, interpretation and presentation of the data for the module as a whole.

Following a brief examination of the rationales for conservation the course discusses some of:(i)the fundamental issues in conservation planning, such as selecting appropriate units for conservation and priority assessment(ii)the research tools commonly used by conservationists, such as population viability analysis(iii)the ways in which ecological theory guides conservation action. These topics are illustrated using case studies of animal and plant conservation in both terrestrial and marine ecosystems from temperate and tropical regions.

10 credits

Symbiosis

In this module, we will explore the nature of symbiosis between plants, animals, bacteria and fungi. We will investigate the 'continuum of symbiosis' from parasitism to mutualism using specific examples drawn from natural and agricultural ecosystems to demonstrate how symbionts regulate the structure and function of host communities and the challenge their control poses. We will investigate methods of controlling parasites as well as how symbionts may be harnessed to regulate host communities in restoration ecology, for biological control and ecosystem service provision (e.g. pollinators) using an integrated teaching approach employing lectures and guest seminars from specific experts in the field.

10 credits

Population and Community Ecology 2

The first part of the module will consider the main characteristics of, and processes behind, climate from the global to the local scale. The second part of the module will examine the physical characteristics of the oceans and their geographical variation, and the role of the oceans in the climate system.

20 credits

Unlocking Past Environmental Changes

The landscape we live in is a dynamic place and has been in the past as well. Huge changes at a global, regional and local scale have occurred in the last 2.6 million years of the earth's history (Quaternary period). These changes are ongoing with implications for both present and future environments. Methods and techniques to investigate past environmental changes from proxy data are outlined and illustrated. The module also looks at how palaeoenvironments have responded to past climate changes thereby putting a context for present day climate changes and predicting future changes.

20 credits

Glacial Processes and Hazards

This module examines glaciers and ice sheets of the World focussing on how they are believed to function and with some consideration of their historic and future changes.

We examine how glaciers and ice sheets come into existence through an understanding of climate and the concept of glacier mass balance. We then consider how glaciers work including on topics such as ice flow, hydrological drainage, ice streams, ice shelves, glacial lakes, and icebergs. Hazards to humankind are also explored. How glaciers modify the underlying landscape is dealt with via a section on glacial geomorphological processes and landforms, and we consider how landscapes evolve under the influence of ice.

20 credits

Understanding Dynamic Landscapes

This module on the earth surface processes looks at the relationship between processes and landforms at a variety of scales in space and time. It examines endogenic processes originating within the earth, exogenic processes occurring at the earth/atmosphere/ocean interface and the way they interact to create landforms. The module discusses geomorphological concepts, frameworks and monitoring techniques and will elucidate a range of quantitative modelling approaches, where numerical expressions are introduced. Case studies drawn from staff research (e.g. aeolian/fluvial/volcanic) alongside practical classes and an appreciation of the importance of new measurement techniques to process understanding, will directly support learning.

20 credits

Core modules:

Issues in Environmental Science

The course is based around a programme of seminars focussed on important current issues in environmental science, natural resources, sustainability and human-environment interactions. A central aim of the module is to develop a forum for Environmental Science students to consider some of the most important, often controversial, aspects of human impacts upon the environment and the sustainability of the planet. Many of these themes will cross traditional disciplinary boundaries, encompassing environmental science, human geography and geopolitics. Introductory seminars by staff will outline subject areas and teaching methods, and provide example seminars and accompanying abstract, discussion points and starter references.

10 credits

Professional Skills for Environmental Science

Environmental science graduates require an appreciation of the needs of professional statutory and regulatory bodies (PSRBs). Employers appreciate the study and research skills developed at university but want graduates that understand the tools in use by environmental science practitioners. This course describes those tools and guides students through the production of their own environmental consultancy report. The module uses lectures, seminars, problem solving sessions, and independent learning to provide professional skills/knowledge. These skills are applied to field visits and laboratory analyses with particular emphasis is given to risk assessment, environmental impact assessment, environmental management and field skills.

20 credits

Optional modules:

Research Project

In this module students will consolidate the skills and knowledge they have gained in earlier levels of study and apply these in a research project. Students will work in small groups, guided by a member of staff, to identify and plan a biological study. They will collect and statistically analyse data, interpret their results and set them in the context of related studies identified from the literature. They will then present their project in the format of a scientific paper. The project may be lab, field or computer based.

30 credits

Dissertation for Geography & Environmental Science

This module requires the student to prepare, organise, research and report a piece of original work on a geographical topic under guidance by a staff mentor.

The finished product is presented in the style, and at the length, associated with academic journal articles.

40 credits

Human Planet

This course examines the historical, social, cultural and political dimensions of sustainability, focusing on food production and natural resource management on the land and in the oceans. Students will learn how key historical developments led to sustainability issues, how geopolitics perpetuates these in the modern world, and how an understanding of these issues can help us to develop more sustainable ways to live in future. Learning will be achieved through lectures and videos, independent study and classroom discussion sessions.

10 credits

Biology and Ethics

As the pace of biological research continues to increase, society and scientists are continuously faced with ethical issues which, in many cases, we are ill-prepared to consider. This course examines areas where biology and ethics interact using a series of topical examples including medicine, agriculture, industry and the environment. In each case ethical concepts will be examined and discussed in the context of the right to privacy, ownership, current regulation, historical perspectives and the public understanding of science.

10 credits

Evolution of Terrestrial Ecosystems

This module examines the evolution of terrestrial ecosystems, from the invasion of the land by plants and animals in the Ordovician (475 million years ago) up to the present day. All of the major events will be covered: the origin of land plants; the invasion of the land by invertebrate animals (worms, insects, etc); the first forests; the origin of amphibians, reptiles, mammals and birds; beginnings of phtogeographical differentiation; origin of the flowering plants etc. Throughout the course the evolution of terrestrial ecosystems will be considered in light of: (i) the interrelationships between global change and evolving terrestrial ecosystems; (ii) plant-fungal-animal interactions and coevolution.

10 credits

Evolutionary Ecology

Why do some organisms weigh a fraction of a milligram and others many tons? Why do some organisms mature in a few days and others need several years? Why make a myraid of tiny eggs rather than few large offspring? This module will address these, and other questions in life history evolution, using a range of modern approaches. All the main approaches of studying evolutionary ecology will be taught (optimality models, evolutionarily stable strategies, quantitative genetics, comparative methods) and their strengths and weaknesses explored. Equal weight will be given to plant and animal systems.

10 credits

Sustainable Agro-Ecosystems

This module highlights the threats to global sustainability, with a particular focus on food production and ecosystem functioning, being caused by human impacts on the environment. The module considers how we have got into the present unsustainable mess ¿ of poor land and natural resource management, under valuing of farmers, life-threatening soil degradation causing flooding, pollution of fresh water and soil insecurity, as well as large numbers of people overconsuming and wasting food whilst others don¿t have enough. It shows that how we sustainably manage agro-ecosystems now, and in the immediate future, will determine the fate of humanity. Soils are the foundations of terrestrial ecosystems, food and biofuel production, but are amongst the most badly abused and damaged components of the ecosphere. Climate change, agricultural intensification, biofuels and unsustainable use of fertilizers and fossil fuels pose critical threats to global food production and sustainable agro-ecosystems - and their impacts on soil ecosystems are central to these threats. The module considers soil ecosystems function in nature and the lessons that we can then apply to develop more sustainable agriculture and ecosystem management.

10 credits

Conservation Issues and Management

This module aims to provide the opportunity for students to develop (i) their knowledge of topical issues in conservation, (ii) their ability to identify potential solutions to real-world conservation problems and assess the likely effectiveness of these (iii) their skills in accessing, interpreting and synthesising the primary scientific literature in the field of conservation and (iv) their ability to think independently. This will be achieved by introducing students, through lectures and independent reading, to a range of topical issues in conservation biology, by showing how research can inform the development of action plans and by illustrating how the success of applied measures to mitigate conservation problems can be assessed. Students will then apply their learning by developing action plans for specific conservation problems.

20 credits

Future Plants: From Laboratory to Field

The module will comprise a 5-day UK residential field class to the Lake District National Park and will cover a range of topics that complement and extend knowledge acquired on the BSc Physical Geography programme, including glaciology, climatology, landscape dynamics and environmental science. Evening lectures during the field-trip will provide relevant background. Small group follow-up sessions will be used to support the presentation of research findings in a science piece.

20 credits

Landscape Evolution

The complex distribution and form of Earth’s topography is the product of both surface and tectonic processes, including interactions with climate at local, regional and global scales. Geomorphological processes and rates are influenced by interactions between these factors, as are the geological and geomorphological hazards in different regions. Informed by on-going research by department staff, this module will deepen understanding of (i) the nature and geomorphological implications of global physical processes that has been developed at levels 1 to 2, (ii) the chronological processes used to constrain contemporary and past landscape evolution, and (iii) the landscape development over a range of timescales and hazard implications of these processes. The module will involve consideration of a range of landscapes and the key controls on their evolution and development.

20 credits

The Planets

This module introduces the student to the fascinating discipline of planetary geoscience and exploration. By using the principles of Physical Geography to study unfamiliar environments, we will explore problems that touch upon themes from climate, tectonics, geomorphology, hydrology, and life. The module begins with the Solar System but soon focuses on planetary-scale matters, using the terrestrial planets (Mercury, Venus, Earth, and Mars) as main examples because of an explosion of knowledge gathered from their observation. We will consider the new perspectives that such knowledge offers on the Earth's dynamic systems.

20 credits

Our Frozen Planet

This research-led module will examine glacial environments in their broadest sense including both their contemporary and former states. Typical themes include:

Geoscientific Data Analysis using MATLAB

Matlab® is a computing environment and programming language with over one million users worldwide. Matlab® also has many less scientific uses; it can be used to edit digital photos and listen to online music. This module will introduce students to Matlab® by way of specific real-world examples taken from Geoscience topics using freely-available data. Initially the module will gently introduce students to the basics of using Matlab® before focussing on five broad topics relevant to Geoscience. At each stage, theory will be accompanied by easy to understand practical examples, with the code used for the examples made available to students. Assessment will comprise computer practicals and a research project; the focus of which will be chosen by each student, but which must use Matlab® to analyse and present data. This module will equip students with a valuable transferable skill – the ability to use a programming language to obtain/generate, analyse and present geoscientific data.
