Jaume Forcada

Marine Mammal Scientist

Biography

Marine mammal expert and population biologist at BAS. Graduated at the University of Barcelona with a PhD on marine mammal population assessment. He was a research associate at the NOAA Southwest Fisheries Science Center in La Jolla, CA (USA), before joining BAS.

I conducted field work and population assessments on marine mammals in the western Mediterranean, western Sahara, Eastern North Atlantic, North Sea, and Eastern Tropical Pacific. Since I joined BAS in 2002, I have spent 13 seasons working mostly on Antarctic fur seals and to a lesser extent on leopard seals at Bird Island, South Georgia.

Research interests

I research how a range of marine mammals and seabirds in the Southern Ocean respond and adapt to increasing environmental fluctuation. Key components of this research focus upon food web interactions (e.g. energetic requirements, prey preferences), life history and population responses (e.g. intrinsic and environmental impacts, individual effects, genotypes), regional density and ecological impact of key species (e.g. seals and resource consumption in areas managed for fisheries) and anthropogenic impacts (e.g. climate change effects on the physical habitat of marine predators).

My specific work focuses:

Empirical data analysis to evaluate population and demographic parameters
Life history, demographic and population modelling to evaluate individual and population responses to environmental variation
Analysis of phenotypic and genetic variation to asses the consequences of climate change
Assessment of environmental variation on population changes of marine predators and their prey.
Krill predator community dynamics in response to climate change
