2.4.1 Estuarine species

Nutrient runoff from the land is a major source of nutrients in estuarine habitats. Shallow-water estuaries are some of the most nutrient-rich ecosystems on Earth, due to coastal development and the effects of urbanization on nutrient runoff. Figure 2.19 shows some typical nitrogen pathways. Nitrogen loadings in rainfall are typically assimilated by plants or denitrified, but septic tanks tend to add nitrogen below the reach of plant roots, and if situated near the coast or rivers can lead to

1.7.5 Theory

Again, research is conducted in a context of existing ideas, evidence, and thinking. One key skill is the demonstration of cognisance of the theoretical context and of how it shapes your own research, including:

  • understanding key theoretical strands and theoretical concepts in your discipline

  • understanding how theory shapes your research question

  • the ability to contribute something useful to the theoretical debate in
