BIOL3074 Global Challenges in Biology

Module Overview

This module will consider human-caused global challenges and their impact on marine and terrestrial ecosystems. We will discuss the main causes of global change, including greenhouse gases, changes in temperature and rainfall, and human land use, as well as how these changes can subsequently trigger other drivers of change (e.g. ocean acidification, soil characteristics, loss of biodiversity) or social challenges (e.g. food security). Biological responses to these global changes will be considered in terms of how organisms, species and communities may acclimatize, adapt or change. After consolidating understanding of the causes of, and biological responses to, global change, we will consider what these impacts mean for ecosystem structure, function, ecosystem services and natural resource management.

Write effectively for readers from a range of backgrounds – communication skill

Syllabus

This module will cover the following topics: 1. The world’s oceans are a major sink for atmospheric CO2 with implications for sea surface temperature, sea levels and the seawater carbonate chemistry (ocean acidification). We will explore the main causes and ecological consequences of warming, ocean acidification and changing sea levels for marine organisms and habitats. The course will look at individual mechanisms that may allow organisms to acclimatise or adapt to changing environmental conditions in marine systems. 2. Land use change in relation to food security – the course will explore environmental issues surrounding large scale geographic change in term of land use, and ways in which ecological knowledge can be used to maximise food production alongside with biodiversity conservation. 3. Greenhouse gases in relation to climate, land use change, and food production – we will explore the biological processes, primarily microbial, underlying greenhouse gas fluxes from soils and ruminant livestock. The causes of soil degradation will be described and the initiatives/programmes designed to restore soil health and sequester greenhouse gases will be discussed. 4. Ecosystem service change in relation to biodiversity loss – the course will also focus on topical and emotive issues such as loss of biodiversity, degradation of ecosystem services and economic valuation of nature, and provide a sound scientific background to these topics that are seldom out of the public eye. The course will illustrate how the increasingly important ecosystem service framework and interdisciplinary approach can be applied to address global challenges.
