Area of Expertise:
Dr. Evgeny Pakhomov is a biological oceanographer with a broad range of interests covering topics from species ecology, at the level from zooplankton to fish, to ecosystem structure as well as physical-biological and biochemical coupling. Most of his research has been done in the Southern Ocean. Recently, he has developed interests in stable isotope ecology, in particular in techniques that use compound specific measurements to reconstruct trophic pathways in pelagic ecosystems. During the past several years, he has also been involved in research studying variability and responses of marine ecosystems to climate change using stable isotopes, large-scale and retrospective analyses. His secondary research interests concentrate on projects studying the land-sea interface, particularly how land use and population density in catchments affect the stable isotope ecology of riverine, estuarine and coastal ecosystems.
Some of his main research projects include:
- Midwater food webs project aims to develop a broad understanding of the fundamental ecological principles driving the composition, diversity, density and stability of the midwater plankton and micronekton communities in the world ocean. It is started as a comparative study to identify the differences/similarities in the community and food web structure (carbon cycling) in different ecological realms, including the mesopelagic zones of polar (Antarctic), temperate (Chatham Rise) and tropical (near Hawaii) regions.
- Rivers Inlet Ecosystem Study (RIES) is formulated around the aim to develop an understanding of factors influencing the early life history of Rivers Inlet sockeye salmon (Oncorhynchus nerka), with special focus on spring plankton abundance in the inlet.
- Salmon resilience – the impact of climate change and fisheries on sockeye salmon’s genetic diversity and population structure: this project aims to gain a better understanding of the interaction of overfishing and climate change in declining fish populations. This study focuses on sockeye salmon a species of key importance in the Pacific Northwest.
- Understanding the ecosystem role of Pacific herring in coupled social-ecological systems: advancing forage fish science: a multi PI NSERC Strategic project aiming to assess ecosystem services provided by forage fish, in particular Pacific herring
