Aquatic

Ecosystems

Through observing the dynamic relationship between stream, nutrients, and pesticides the Ecosystem Services team can better understand how coastal ecosystems are impacted by these variables. In addition to the associated impact on the aquatic organisms and the intricate food webs these ecosystems contain.

Goal

To develop an understanding of how both terrestrial and aquatic farming can impact the resilience and functioning of adjacent aquatic ecosystems.

Using the support of local crop and fish farmers, the aquatic team is looking at how farming intensity, farming techniques (e.g., ALUS; alternate land use services) and harvesting alter the abiotic conditions, the structure, and function of individuals to whole ecosystems.

Projects

Land Modification and Nutrient Loading

Measuring the abiotic and biotic structure (biostructure and biodiversity) from genes to whole ecosystems in streams, rivers and lake ecosystems along a gradient in farming intensity (land modification).

Current research is looking at: 

Local streams

Regional: Stream to Coastal Ecosystems

 
 

Biotracer Development and Bioinformatics

Developing biotracer techniques for monitoring the health, diversity and structure of aquatic ecosystems.

Current research is looking at: 

Testing the efficacy of eDNA barcoding in characterizing the biodiversity in benthic streams. 

Using cortisol content of fish scales as a bio-indicator of environmental stress.

Quantifying global seafood using multi-tracer quantitative techniques (AI).

Sustainable Fisheries

Developing techniques to monitor and manage fisheries sustainably both locally and globally.

Current research is looking at: 

Developing early warning signals to detect impending changes to aquatic ecosystems

Socio-economic models and fishery sustainability

Using bio-tracers to understand how anthropogenic subsidies affect native aquatic food webs
