LEC.101: Global Environmental Challenges

  • Terms Taught: Full Year Course
  • US Credits: 4 Semester Credits
  • ECTS Credits: 8 ECTS
  • Pre-requisites: None

Course Description

At the beginning of a student's university experience it is important that a wide-angle view of the environmental world is taken. The importance lies in exposing students to the breadth of topic and approach taken to successfully characterise and solve environmental problems in the broadest context. The module deliberately links themes from the natural and social sciences to focus on key processes and issues in ways that are relevant to students on all LEC degree schemes. Whilst avoiding specialist technical and theoretical details (these are dealt with in subject-specific modules), the module avoids superficiality by placing emphasis on the complex interactions between key environmental and societal processes, and on breadth of new knowledge. Topical themes are taught at a variety of scales, with emphasis on linking the global and the local. At the end of the module students are very well informed of the subject diversity they could study on progression to Part 2 and, therefore, equipped to make educated decisions about the direction of their degrees.

Educational Aims

Through lectures and tutorials the module will teach students critical thinking skills and will require students to understand and evaluate key contemporary environmental issues from a variety of perspectives. Key research, communication and safety skills that underpin the attainment of environmental knowledge and understanding are delivered through small group, team and individual work.

Outline Syllabus

Global Environmental Challenges emphasises the multidisciplinary and interdisciplinary approaches that must be taken in order to understand and solve environmental problems. The module syllabus is aimed at providing LEC Part 1 students with an appreciation of these holistic approaches in relation to their individual backgrounds and degree schemes in terms of both introductory academic knowledge and foundation skills. The curriculum adopted is based around LEC's three research actions. This has the very important embedded benefit of giving new LEC students a clear view of LEC activities as well as introducing 60% of LEC academic staff and their associated areas of expertise. Delivery of academic material is through 38 bi-weekly presentations whilst key skills are nurtured through 11 fortnightly small-group tutorials that support a project-based approach. The generic curriculum is given below, followed by a more detailed specification.

Understanding a changing planet

The global environment and society are now threatened by unprecedented changes resulting from human activities, including intensive agriculture and fossil fuel use, as well as facing natural hazards such as volcanic eruptions or climatic extremes. "Global Environmental Challenges" explores these threats through a series of research-informed presentations from a broad cross-section of expert LEC staff. LEC recognises the need to balance disciplinary and interdisciplinary understanding that addresses the physical, chemical, biological and social aspects of "Global Environmental Challenges". We work together to contribute to finding sustainable approaches to resilience and adaptation. LEC.101 aims to start students on the road to understanding and contributing to addressing "Global Environmental Challenges".

Improving global stewardship

The environment supplies the resources on which the health, wealth and wellbeing of all societies depend; however, unsustainable resource use is damaging to societal wellbeing. Interdisciplinary interactions that embrace both the social and natural sciences improve environmental resource management in ways that respect not only the need for environmental protection but also sustainable development that is just, equitable and inclusive. "Global Environmental Challenges" explores sustainable approaches to food production, clean air and water; energy and essential minerals, as well as the ecosystems that provide a range of services from fertile soils and sustainable pest control to cultural wellbeing.

Innovation for a better environment

LEC recognises that sustainable development depends on promoting sustainable patterns of consumption and production as well as protecting and managing the natural resources vital for economic and social development. "Global Environmental Challenges" encompass, therefore, eco-innovation, which is innovation that reduces the environmental impact of products, processes and services or improves the efficient and responsible use of resources.

Course Description

Aquatic ecosystems host biodiversity which helps to underpin some of the most important ecosystem services on the planet such as carbon storage and sustainable fisheries. Understanding what is there and what it does is vital if we are to maintain and manage aquatic resources and combat the multiple stressors that they face. Through a series of lectures and practicals, students will be introduced to the concept of water as a medium for life and the challenges that poses for organisms spanning from microbes to whales and including those organisms that are subsidised by marine / estuarine production. A focus will be upon ecophysiology and how organisms respond and adapt to environmental gradients such as oxygen availability, salinity, pressure or exposure. The relationship between structure and function, and the importance of considering scales of both space and time will be stressed throughout. The module will finish with an exploration of the ecosystem services provided.

Theory from the lectures will be supported by a site visit to Morecambe Bay to make some field observations and collect samples for a subsequent lab session. Two further lab-based practicals will use fish to investigate aquatic adaptations.

LEC.246: Environmental Physiology

  • Terms Taught: Lent / Summer Terms Only
  • US Credits: 4 Semester Credits
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: Normally biology or biochemistry majors only.

Course Description

Macroscopic plants and animals interact with their environments in what appear to be fundamentally different ways. Animals, especially humans, possess sophisticated control and co-ordination systems, which regulate their physiology as well as complex patterns of behaviour. Plants, apparently, lack such sophisticated responses, yet both groups are clearly highly successful. Environmental Physiology ‘crosses the great divide’ between animal and plant biology, examining the whole-organism responses of animals and plants to light, pollution and disease-causing micro-organisms. We consider how such responses are controlled and co-ordinated, and how information is communicated between individuals in both animals and plants. The scope of LEC.246 is broad, extending from the consequences of environmental change on human health to communication between plants. The theme is the central role of physiology in determining a wide range of biological responses, with the overall aim of providing an integrated understanding of the mechanisms by which both animals and plants cope with their environment. The course includes nine hours of lab work.

Educational Aims

After completing this course students should be able to:

  • Describe how animals and plants perceive light.
  • Describe the effects of ultraviolet light on animals and plants and the mechanisms for protection from its damaging effects.
  • Show how various pollutants affect the health of plants and humans.
  • Describe the various forms of innate immunity in animals and discuss the conservation of anti-microbial defence mechanisms during evolution.
  • Show how plants resist infection by microorganisms.
  • Describe mechanisms by which plants perceive environmental signals and co-ordinate their responses to them

  • US Credits: 4 Semester Credits.
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: Equivalent to LEC.142 and LEC.243

Course Description

Employers expect graduate biologists, especially those aiming for careers as field biologists or ecologists, to have gained experience of basic field biology skills and common survey techniques. This module aims to provide students with these essential field skills in order to increase their competitiveness and potential for accessing the job market at the end of their degrees. The module will focus primarily on identification skills of several groups of organisms including plants and animals. This knowledge provides the basis for characterising and identifying habitat types in order to carry out environmental assessments. Students will be introduced to the Phase I habitat survey method and other sampling techniques appropriate for assessing populations of indicator species of each habitat. This module will be delivered in the field at Lancaster University field station and will include, where possible, excursions to natural habitats in the surrounding areas, such as the Yorkshire Dales National Park and the Arnside and Silverdale Area of Outstanding Natural Beauty.

Educational Aims

On completion of this module students will be able to:

  • Use field guides and keys for taxonomic identification.
  • Demonstrate identification skills of the key taxa used in the module, such as (a) common plants in order to map habitats and identify standard habitat types and (b) common and indicator species of target habitats from one or more insect groups.
  • Use the Phase 1 habitat survey manual to classify target habitats within broad categories.
  • Use field equipment for recording a set of environmental variables and ecosystem processes.
  • Identify appropriate sampling methods and apply them in the field.

Outline Syllabus

The module will be an intensive 5-day course in the middle of summer term, likely Week 24 (mid May). The module will have five sections, almost entirely delivered in the field by several lecturers. The main field site will be Hazelrigg Lancaster University field station. The students will be taken through a habitat and biodiversity (indicator taxa) survey at the Hazelrigg field site. There will be also short sessions at the site on: monitoring bird breeding parameters (including demonstration of handling and ringing birds); moth trapping (including species level identification of macro-moths) and small mammal trapping (including species level identification and demonstration of tagging). In addition there will be two days when excursions will be made to off-campus sites (e.g. to a species-rich meadow in the Yorkshire Dales and to sites of highly diverse insect communities such as the Morecambe bay region to see Fritillary butterflies).

Workshop (2h) in week 23:

  • Introduction to the module and health and safety in the field.

Day 1 (8h) in week 24:

  • Introduction to the Phase I habitat survey method, focusing on several habitats present at the field station (grasslands and woodlands) and including some elements of the National Vegetation Classification.
  • To complete a Phase I survey it is necessary to have a general knowledge of plant species. Therefore most of the day will focus on plant identification using identification keys and field guides.
  • Session on bird nest monitoring.

Day 2 (8h) in week 24:

  • Excursion to a species-rich meadow in the Yorkshire Dales, practising plant identification skills.

Day 3 (8h) in week 24:

LEC.248: Vertebrate Biology

  • Terms Taught: Lent / Summer Term only
  • US Credits: 4 Semester Credits  
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: Equivalent to LEC.142

Course Description

Vertebrates (including fish, amphibians, reptiles, birds and mammals) display a staggering diversity of shapes and sizes, and are adapted to a wide array of environments from hot deserts to freezing oceans. The aim of this module is to introduce you to this broad range of forms and functions, putting molecular, cellular, physiological and behavioural processes firmly within a whole organism and evolutionary context. This module will introduce you to the major vertebrate taxonomic groups; it will explore how they have evolved to exploit different environmental niches on land, in water and in flight; and how their anatomy, reproduction, thermoregulation, feeding, breathing, moving, and communication have all become fine-tuned to cope with the challenges of their evolved lifestyle.

Educational Aims

The specific educational aims are as follows:

  • Knowledge and Understanding: On successful completion of this module students should be able to link vertebrate physiology and structure with its function and evolution. They should be able to explain how organs and systems differ across taxonomic groups and how they have evolved to match the animals lifestyle and environment. They should be able to list the major vertebrate taxonomic groups, describe their evolutionary relationships to each other and summarise key concepts in areas such as anatomy, reproduction, thermoregulation, digestive biology, communication and ageing.
  • Skills: On successful completion of this module students should be able to:(i) Distinguish between the various vertebrate taxonomic groups based on form, physiology and behaviour.(ii) Describe how form, physiology and behaviour have evolved both through evolutionary time and via adaptation to environmental challenges.(iii) Use data collected by modern tracking devices and image analysis software to infer movement behaviours at continental scales and adaptations at local scales.(iv) Describe how different traits have evolved in different taxonomic groups to tackle similar environmental challenges (e.g. flight, thermoregulation, reproduction, etc.).

LEC.331: Food and Agriculture in the 21st Century

  • Terms Taught: Lent / Summer Terms only
  • US Credits: 4 Semester Credits
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: No pre-requisite, but college level Geography preferred

Course Description

This module will explore the social, political and environmental challenges facing food systems in the world today. We will look at the history, culture and development of contemporary food systems through a focus on our interactions with plants, animals and the landscape before bringing the discussion up to the present with an analysis of key debates surrounding food security and food sovereignty. Through an exploration of case studies from across the globe, we will consider the connections between changing diets, landscapes and agrarian reform and challenge you to develop innovative and alternative solutions for the future.

The knowledge and understanding on the history, contemporary debates, and future of food and agriculture that you develop in this module will be transferable to contemporaneous or further study across the spectrum of human-environmental relations. This is because food and agriculture have always been fundamental to society while at the same time being principal drivers of environmental change at multiple scales. Learning would hence be applicable elsewhere in examining the nature and evolution of 'global assemblages' and landscape-society inter-relationships. This module will develop your skills of debate and analysis drawing on environmental history, human geography, anthropology, sociology, historical and political ecology and cultural studies.

Educational Aims

On successful completion of this module students will be able to:

  • Debate current issues around the origins of food and agriculture and their relationships to human evolution and history
  • Describe how the post Columbian world system (e.g. post 1491) and colonialism profoundly transformed food and agriculture worldwide
  • Describe how conventional agriculture and the world food system emerged and how it functions today
  • Describe with the nature of and debates around alternative agricultures such as organic and agroecology
  • Describe the social, ethical, economic and environmental challenging facing food systems today
  • Understand the key differences between approaches based on food security and those based on food sovereignty, fair trade and food justice
  • Understand the connections between production and consumption and how these shape the food systems that we see in place today
  • Describe and evaluate some of the potential 'alternative' solutions to food security and how these sit in relation to more 'conventional' perspectives

Outline Syllabus

This 10 week course consists of 1 lecture and 1 hour of workshop per week for 9 weeks, with a local fieldtrip in week 8. Weekly topics are as follows:

LEC.342: Issues in Conservation Biology

  • Terms Taught: This module runs in weeks 1-5 of Lent Term only.
  • US Credits: 4 Semester Credits
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: Equivalent to LEC.145

Course Description

Conservation of biodiversity is a major goal of humanity, yet justifications for conservation are multifaceted and their relative importance varies among people and societies. Conservation objectives may also come into conflict with economic activity and development. While providing a grounding in the science of biological conservation this course also focuses on some of the key current challenges in conservation biology, where conservation objectives may trade-off against other human objectives. The course highlights our emerging understanding of the complex relationships between biodiversity conservation, the health of ecosystems and human wellbeing.

Educational Aims

On successful completion of this module students will be able to:

  • Demonstrate a broad understanding of how humanity benefits from ecosystem services and the primary justifications from conserving biodiversity.
  • To discuss in detail several case studies where conservation comes into conflict with other economic and social objectives.
  • To discuss the challenge of conserving biodiversity while meeting the world's growing demand for food.
  • To display a deep understanding how the developing world will meet the dual challenges of economic development and biodiversity conservation.

Outline Syllabus

The proposed module will be arranged around two 2h sessions each week. There will also be two field excursions to local sites of interest, which will replace the discussion sessions on the respective weeks. The module will be taught by a broad array of staff within LEC representing ecological, sociological and economic aspects of conservation biology. There will also be sessions run by local professionals who manage trade-offs between economic activity and conservation.

A provisional module outline follows:

  • Introduction - An overview of the current status of biodiversity and ecosystem services. Followed by a discussion of the values of biodiversity.
  • Wild meat - the impact of hunting on biodiversity and a discussion of the socio-economic drivers which result in over-harvesting and how these can be addressed.
  • Managing fisheries - a local perspective on shell fish harvesting in Morecambe bay and the trade-offs between human use and bird conservation in this internationally important coastal habitat. Lecture plus excursion led by Bob Houghton of the Inshore Fisheries & Conservation Authority.
  • Land sparing or wildlife friendly farming? Should agriculture be done as intensively as possible over minimal land area or using wildlife-friendly methods over larger areas? What are the relative costs and benefits of these approaches.
  • Predator Control in Conservation - an examination of arguments for and against predator control in uplands managed for sport hunting, using the Forest of Bowland as a case study. Lecture plus excursion.
  • Biodiversity and human wellbeing - an examination of the varied links between biodiversity, food provision and health.
  • Pollutants and biotic response in aquatic systems - Managing pollutants to conserve biodiversity in rivers.

LEC.348: Host-Parasite Interactions

  • Terms Taught: Weeks 1-5 of Lent Term only.
  • US Credits: 4 Semester Credits
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: None

Course Description

Plants and animals in their natural environments interact with a wide range of other living organisms. These include both beneficial interactions and damaging encounters with parasites, pathogens and herbivores. This module seeks to build on introductory material from LEC.246 to introduce students to a more detailed appreciation of the range and complexity of plant and animal interactions with parasitic organisms. We will examine the different kinds of organisms that have evolved a parasitic lifestyle and the ways in which they parasitize their hosts. In parallel, the module will introduce the different strategies that plants and animals use to defend themselves, including the recruitment of other organisms to act as allies. The continuing conflict between hosts and parasites results in a so-called 'evolutionary arms race', and we will cover a range of examples of the co-evolution of host defences and parasite counter-measures which enable successful parasites to overcome these defences. The module will also examine the evolutionary costs and benefits of defence, and the evidence for short and long-term immunological memory.

Since the module is aimed primarily at addressing ecological and physiological questions rather than the biomedical aspects of parasitology, the focus will be on invertebrate rather than vertebrate hosts.

Educational Aims

On successful completion of this module students will be able to:

  • Describe the main groups of parasitic organisms and their lifestyles
  • Describe structural and behavioural defences against parasites, pathogens and herbivores in plants and animals
  • Describe the key features of innate and adaptive immunity in plants and animals
  • Identify the main selective pressures shaping the evolution of host resistance to parasites
  • Explain why many defence mechanisms are inducible rather than permanently expressed
  • Explain how specialist herbivores and parasites have co-evolved with their hosts to overcome resistance
  • Describe examples of the links between genetic, biochemical and physiological processes and ecological scale interactions between different organisms
  • Explain the mechanistic basis for, and ecological significance of, immune priming and immunological memory
  • Discuss the need for interdisciplinary research in the field of resistance/immunity to pests and diseases

Outline Syllabus

The module will be taught over 5 weeks, with 2 lectures per week, supported by weekly practical and workshop sessions.

Lecture Topics include:

  • Introductory lecture on evolutionary parasitology
  • Animal defence immunity
  • Plant defence against pathogens and herbivores
  • Parasite strategies to evade host defences
  • Effects on parasitism of interactions with other organisms
  • Host defence trade-offs

LEC.349: Sustainable Agriculture

  • Terms Taught: Lent / Summer Terms Only
  • US Credits: 4 Semester Credits
  • ECTS Credits: 7.5 ECTS
  • Pre-requisites: College level biological or environmental science

Course Description

Modern resource-intensive agriculture has proved incredibly successful in delivering relatively abundant, cheap food (at least in the developed world), but sometimes at considerable environmental cost. Therefore the general public is usually keen to embrace ‘sustainable agriculture’ but is generally unaware of the economic and food production costs of proposed changes in crop management. By emphasising the concept of crop resource use efficiency, this course also focuses on the viability of less intensive agricultural systems.

Educational Aims

On successful completion of this module students will be able to:

  • Identify and understand key issues affecting the sustainability of agriculture, and critically appraise the literature on these issues
  • Understand the economic / societal issues constraining the adoption of more environmentally sustainable agriculture
  • Discuss alternative scenarios and solutions for key environmental problems associated with agriculture
  • Write cogently and critically about key environmental problems associated with modern intensive agriculture and alternative, sustainable solutions

Outline Syllabus

The module will be arranged around two 1 hour lectures each week, that cover a wide range of contemporary management practices and technologies relevant to sustainable agriculture (eg. role of GM crops, irrigation management, crop rotation, intercropping, crop protection) that may vary from year-to year. An additional 3 hour workshop (Weeks 2, 3) or laboratory practical (Weeks 1, 4, 5) will occur later in the week where the emphasis will be on:

  • Assessed student oral presentations on environmental (water or carbon) footprinting of a selected commodity
  • An experiment to test the relative benefits of chemical and biological fertilisers, where experimental design is undertaken by students working in groups
