BZ3220 - Population and Community Ecology

Credit points: 3
Year: 2012
Student Contribution Band: Band 4
Administered by: School of Marine & Tropical Biology

Animals and plants live in populations. Groups of populations inhabiting the same area make up biological communities. Processes operating at these levels control the biodiversity of habitats and regions. This subject presents the conceptual framework needed to understand these processes and illustrates that framework using examples drawn from many systems including tropical rainforests, which are among the most complex and diverse ecological systems in existence. Topics presented include population growth, species interactions, community patterns and dynamics, food webs and the effects of disturbance and scaling on diversity. In addition to an increased understanding of concepts, students gain hands-on experience in tropical research.

There are additional charges for this subject; please contact the School for details.

Learning Outcomes

  • gain an ability to critically evaluate original research;
  • understand how communities can be defined and measured and how processes act at the community level;
  • understand the composition and structure of rainforest communities and how they are affected by basic processes;
  • understand modern concepts of population processes and species interactions and their relation to the structure and function of biological communities.

Graduate Qualities

  • The ability to define and to solve problems in at least one discipline area;
  • The ability to think critically, to analyse and evaluate claims, evidence and arguments, and to reason and deploy evidence clearly and logically;
  • The ability to find and access information using appropriate media and technologies;
  • The ability to evaluate that information;
  • The ability to select and organise information and to communicate it accurately, cogently, coherently, creatively and ethically;
