April 2021. Many congratulations to Louise Rutterford, who has successfully completed her PhD studying the impact of climate change on European shelf fish communities. Many thanks to Mike Burrows and Orly Razgour for externalling.
April 2021. Pleased to have contributed to a paper taking steps to resolve the freshwater crab diversity East Africa, led by Neil Cumberlidge and Emily Johnson, out now in European Journal of Taxonomy.
March 2021. How do fishers balance physical risk and economic reward? Our recent paper, led by Nigel Sainsbury, addresses this question in fishery of southwest England. Out now in Global Environmental Change.
August 2020. In 2013 we found populations of Korogwe tilapia in lakes in the south of Tanzania, hundreds of miles from where we expected them to be in the north of the country. A new paper in Molecular Ecology shows that the southern populations are genomically and morphologically distinct from those in the north.
The southern populations fit the criteria to be considered a new species - but they are already hybridizing extensively with introduced large-bodied Nile tilapia. Unique diversity is being lost before it is even recognised.
Well done to Tabitha Blackwell and the teams in the UK and Tanzania for their work on this, it's been a big effort. I'm hoping some of these unique southern Korogwe tilapia can be conserved before they are admixed to extinction.
July 2020. Well done to Katherine Maltby! Her paper projecting the effects of climate warming on European marine fishes in Journal of Applied Ecology.
June 2020. Toby Champneys has been quantifying the competitive behaviour of invasive and native tilapia fishes in laboratory conditions. The paper is in Hydrobiologia.

December 2019. Have a look at our new study led by Hannes Svardel showing the hybrid origins of the spectacular radiation of cichlid fishes in Lake Malawi, out now in Molecular Biology and Evolution.
September 2019. Welcome to new postgraduate students Harry Layfield and Sophie Ward. Harry will be studying for a PhD on the ecology and evolution of African riverine faunas, while Sophie will be studying for a research Masters focussed on riverine fish morphological diversity. I am also looking forward to co-supervising Costanza Zanghi (predator-prey interactions in a changing world) and Kosta Manser (freshwater electric ecology).
September 2019. We are pleased to be starting a new GCRF Translational Award on the eDNA surveillance of invasive tilapia in Tanzania next month. It will be great to continue working with Tanzanian colleagues, and to help the expanding aquaculture sector.
July 2019. Well done Rupert Collins et al. - our new paper on the limitations of using COI for fish metabarcoding out now in Methods in Ecology and Evolution.
July 2019. Nile tilapia is indigenous to Lake Tanganyika, in all probability. See our new paper in Environmental Biology of Fishes.
June 2019. Are mesopelagic fish really rare in polar seas as acoustic surveys suggest? Well, probably not... it's just that that they are less detectable because polar species tend not to have swimbladders. Read all about it in Tracey's new paper in Proc Roy Soc B.
May 2019. Our study of Lake Malawi cichlid fish lateral lines using microCT scans is out now in iScience. Well done Duncan Edgely who drove this forward!
May 2019. Lovely new paper from Jennifer Freer and colleagues exploring potential influences of climate change on Southern Ocean myctophids - out now in Diversity and Distributions.
April 2019. I'm pleased to have contributed to the most complete phylogeny of the tilapia genus Oreochromis. These fish are of immense importance for fisheries and aquaculture, and now we have a clearer idea of their evolutionary history. The work, published in Molecular Phylogeny and Evolution, has been led by Julia Day (UCL) and Antonia Ford (now Roehampton).
