LF265-15 Ecological Principles and Processes
Introductory description
This module is designed to give an overview of ecological principles and processes to aid an understanding of the natural world, and to provide a foundation for later studies for students with a special interest in environmental studies.
Module aims
This module will enable students to:
- understand key ecological principles.
- appreciate the complexity of ecosystems and the integration of ecological processes within these systems.
- recognise the role of environmental influences on different levels of organisations within ecosystems.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Lecture Outlines
-
Introduction (DC)
What is ecology? Introduction to the module and lecturers. What does ecology mean for me? The diversity of life on earth.
PART A: The ecology of single species -
Organisms and their environments (DC)
Conditions, resources, the niche concept. -
The evolutionary context (CA)
Integrating ecology and evolution, natural selection, genotype, phenotype, nvironment, phenotypic plasticity, local adaptation, the species concept. -
Life histories (DC)
Ecological strategies, life history evolution, traits and functional ecology, resource allocation, evolutionary stable strategies. -
Single species populations (DC)
Single species: exponential growth, competition or the environment? Population cycles, Chaos.
PART B: Interactions between species -
Interspecific competition and predation (DC)
Trophic interactions: Interspecific competition, predation and predator-prey interactions, indirect interactions (apparent competition). -
Parasitism and disease (DC)
Importance of parasites, life history strategies and co-evolution, host defence, host manipulation. Parasite population ecology -
Living together (DC)
Mutualism, commensalism, engineers; pollination; ant mutualisms; gut inhabitants; mitochondria and chloroplasts; bodyguards; mycorrhizae; lichens; agriculture.
PART C: Biodiversity and the ecology of communities -
Biodiversity (CA)
Species richness, genetic richness and biodiversity, species area relationships and island biogeography, richness and ecosystem functioning, human impacts. Why species and genetic diversity is important. -
Ecological succession (CA)
Disturbance, colonisation, succession, community dynamics, community assembly, diversity and productivity. -
Community ecology (DC)
Introduction to food webs, flow of energy through ecosystems. Metapopulations. Community modules. Trophic cascades. -
Ecological and evolutionary genetics (CA)
Evolutionary ecology from the individual to the ecosystem.
Learning outcomes
By the end of the module, students should be able to:
- Level 5 understanding of key ecological principles, including environmental niches, natural selection and phenotypic plasticity
- Level 5 understanding of how species interact, including competition, predation, symbiosis and parasitism
- Level 5 understanding of biodiversity and the ecology of communities
- level 5 understanding of evolutionary genetics
