I am an animal ecologist with an interest in how populations and communities respond to environmental change, predation and management. My research group has an aquatic ecology focus with current projects ranging from coastal fisheries, aquaculture, habitat restoration and freshwater management and ecology. ############################# External Collaborations Professor Lennart Persson, Dr Pär Byström, Dr Tomas Brodin (Umeå) and Professor Andre de Roos (Amsterdam) Professor Tim Benton (Leeds) and Professor Stuart Piertney (Aberdeen) Jo Preston (Portsmouth), Chris Houghton (Southampton), Alison Debney, Thea Cox and Charlie Endsor (ZSL), Tim Glover, Morven Robertson and Jacob Kean Hammerson (Blue Marine Foundation), Philine Zu Ermgassen (The Nature Conservancy) Tamas Muller (Szent István University, Godollo) Dr Arne Schroder (Berlin) and Dr Anieke van Leeuwen (Princeton) Professor Bernt-Erik Saether and Vidar Grotan(NTTU, Trondheim), Dr Ron Bassar (Oxford), Robert Arlinghaus (Berlin), Andres Lopez-Sepulcre (CNRS) Rob Dyer (Essex and Kent Inshore Fisheries and Conservation Authority -IFCA) Jane Heywood & Ewan Hunter (CEFAS) Martin Taylor (University of East Anglia) ###################################################################################### Undergraduate Final Year projects in the Cameron lab Here is a list of project areas I could offer in the 2019-20 academic years Some are listed under summer or autumn/winter as does not matter when it is done Summer Projects Marine fish behaviour and ecology (1 field based project available) Substrate and habitat selection of native and non-native oysters (summer - field based) (NEW) Summer breeding birds ecology and behaviour - (1-2 field based - with Essex&Suffolk Water and BTO/WWT) Temperature dependence of oyster behaviour and physiology (1 project - lab based) Autumn/Winter term projects Eco-evolutionary feedbacks from sexual selection to population dynamics Local adaptation in zooplankton to predation trade-offs Habituation to recreational disturbance in Estuarine Birds (winter project) (NEW) Winter Waterbirds ecology and behaviour - (1-2 field based - with Essex&Suffolk Water and BTO/WWT) Size structured functional responses of temperate and tropical freshwater fish Life History evolution / Animal Behaviour in the Trinidadian guppy (Poecilia reticulata) Temperature dependence of oyster behaviour and physiology (1 project - lab based) Marine fish behaviour and ecology (1 field OR 1 lab based based project available) I am happy to discuss other project ideas you may have

Research and professional activities

Research interests

Animal movement and dispersal

Open to supervise

Estuarine ecology, global change and European oyster restoration

We work on saltmarsh ecology, the use of estuaries as nursery habitats for juvenile fish, the ecology and conservation of endangered European flat oysters and the thermal ecology of animals in coastal environments

Open to supervise

Evolution of Ontogenetic Niche Shifts and Asymmetry in Guppies

At present this research in my lab is being led by PhD student Matt Bond, but it represent a larger body of work develop by Lennart Persson (Professor of Ecology, Umea) and Andre de Roos (Professor of Theoretical Ecology, Amsterdam).
