Research interests

My research interests are diverse, but extend across the fields of evolutionary ecology, trophic ecology, ecosystem function and conservation. I typically work in aquatic systems and have no particular loyalty to any point along the salinity gradient. My research typically involves the use of stable isotope analysis combined with other techniques, including population ecology, molecular genetics and morphometrics.

Research Interests: The ecology, evolution and conservation of fish and other aquatic taxa, including jellyfish.   Rapid speciation & cryptic population structuring.   Ecosystem function and cryptic energetic subsidies.  The development of stable isotope analysis as a standard method in aquatic ecology.

Study taxa:   Coregonid fishes including pollan (Coregonus autumnalis), whitefish (Coregonus lavaretus), European eel (Anguilla anguilla), guppies (Poecilia reticulata), 3-spined sticklebacks (Gasterosteus aculeatus), Orestias chungarensis. Macroalgal-reef associated fishes of the Chilean coastal zone e.g. Cheilodactylus variegatus, Paralabrax humeralis & Pinguipes chilensis.

Study sites:  I am involved in studies examining the ecology of lakes, rivers and coastal zones across the world, with current focus on Ireland and the UK (especially Lough Neagh and Strangford Lough), Chile, and Finland.

My work is multidisciplinary and amongst others, I have ongoing research collaborations both with colleagues within QMUL and elsewhere, including The Helmholtz Center for Marine Sciences (GEOMAR), Queen's University of Belfast, University of Helsinki, University of Oslo, Centre for Ecology and Hydrology, University of Chile, Santiago, Environment Agency, Glasgow University, Scottish Natural Heritage, University of the West Indies, National University of Ireland, Galway, University College Cork, University of Konstanz, University of Köln,and the Institute of Vertebrate Biology, Czech Republic.

In December 2011, Thompson Reuters identified our (Graham & Harrod, 2009) paper on fish and climate change as an Emerging Research Front paper in the field of Plant & Animal Science on Sciencewatch.com

In December 2012, Oceanography discussed our (Syväranta et al. 2012) recent paper suggesting that the diet of ocean sunfish Mola mola extended beyond that of obligate jellyfish predators. In the same month Carl Zimmer summarised for National Geographic, a recent paper (Manousaki et al., 2013)  where we used isotopic analysis to support advance molecular techniques to understand rapid evolution of lip-size in crater lake cichlids.
