SOES3013 Zooplankton Ecology and Processes

Module Overview

Aims and Objectives

Module Aims

In this course you will learn to recognise the diversity of marine zooplankton taxa; the factors that regulate their distribution and abundance; and the fundamental role they play in marine pelagic ecosystems. The specific objectives are to: 1. Establish the role of zooplankton in the pelagic marine community and introduce holo- and mero-plankton diversity and functional biology. 2. Review zooplankton reproduction and life cycle strategies. 3. Understand how biotic and abiotic factors regulate zooplankton distribution and abundance at various temporal and spatial scales; larval transport and meroplankton settlement. 4. Review the technologies available to sample the community in the field and to introduce procedures for laboratory analysis of abundance and biomass. 5. Establish the role that zooplankton play in marine pelagic food web ecology; introducing the impact of zooplankton grazing, zooplankton as predators and ‘alternative’ food resources. 6. Critically evaluate methods used to determine diet, feeding rates and trophic role. 7. Introduce the responses of zooplankton to tidal advection and behavioural / physiological methods to avoid displacement; diel vertical migration and its impact on the individual and community. 8. Assess how zooplankton is used as indicators of water mass movements and hydroclimatic change in the global ocean.

Learning Outcomes

Having successfully completed this module you will be able to:

  • Appreciate the diversity of mero- and holo-plankton; be able to carry out a taxonomic description of several marine zooplankton groups.
  • Have a practical working knowledge of zooplankton sampling; be able to identify common species of zooplankton found in UK estuarine and coastal waters.
  • Understand how biotic (life history strategies, behaviour, trophic interactions) and abiotic (hydrodynamics, climate) factors regulate zooplankton distribution and abundance.
  • Appreciate the behavioural and physiological responses used by zooplankton to counter tidal advection/population dispersal and to undertake 24-hour diel vertical migration.
  • Understand the role that zooplankton play in marine pelagic food webs; appreciate the constraints to measuring zooplankton feeding in the laboratory and in the field using different methodological approaches.
  • Be aware how plankton dynamics and pelagic ecosystem function will differ in response to hydroclimatic variability, through the use of zooplankton indicator species and long-term datasets.
  • Use a range of library information services to aid production of well-structured written reports.

Syllabus

Marine zooplankton communities consist of permanent and temporary members, including the larvae of many fish and benthic invertebrates, thus acting as vehicles for population exchange and diversification. Zooplankton play an important role in the functioning of marine ecosystems and in biogeochemical cycles, because they are key components of the trophodynamics of pelagic ecosystems, linking primary production to higher trophic levels - fish, mammals and seabirds. In addition to their functional role, marine zooplankton are considered to be good indicators of climate change because a) most species are short lived, which leads to tight coupling between environmental change and plankton dynamics, and b) they are free floating, so respond easily to changes in temperature and oceanic current systems by expanding and contracting their ranges. In this course you will learn to recognise the diversity of marine zooplankton taxa; the physiological and hydroclimatic factors that regulate their distribution and abundance; and the fundamental role they play in marine pelagic ecosystems. Responses of individual zooplankters to their environment will be studied by examining factors regulating tidal advection, larval settlement and the implications of diel vertical migration. The useful of plankton indicators of climate change will be explored. Practical classes are designed to introduce the diversity of mero- and holo-planktonic forms and to train students in formal taxonomic identification of temperate water species. Methods for evaluating feeding rate and diet will be carried out during a critique of a research paper.
