Understanding variation in marine protected areas: a spatio-temporal study of species richness and oceanographic patterns across the Galápagos Islands


Project Description

Human impacts across the world’s oceans are causing profound changes in ecosystem structure and species distributions. Understanding such ecosystem-wide changes requires a comprehensive baseline that can be widely used to track, manage and minimise perturbations. Progress in ocean biodiversity research has to date been limited by inconsistent data collection and inadequate levels of interaction between oceanography and biology. This project will combine the study of environmental DNA (eDNA) to detect marine species richness patterns with cutting-edge oceanographic modelling.
The rapid development of eDNA metabarcoding methods (i.e. the study of genetic material recovered from environmental samples such as seawater and sediment, to simultaneously identify species) has allowed the reliable sequencing of genomic material across the entire tree of life. This project will use eDNA metabarcoding to provide the first large-scale study of species richness patterns, from microbes to whales, of the Galápagos Islands. The objectives are:
1. Quantify oceanographic drivers shaping species richness patterns and population connectivity.
2. Predict impacts of contemporary climate dynamics on marine ecosystems.
3. Unravel the effects of human impacts on marine species richness patterns.
Our approach will allow forecasting future changes in ocean currents and evaluate their effects on coastal and shelf-sea ecosystems across the archipelago.
