The tomato powdery mildew fungus Oidium neolycopersici.
Powdery mildew fungus, reported to attack over 60 species in 13 plant families, particularly members of the Solanaceae and Curcubitaceae, is extremely common in glasshouse tomatoes world wide but increasing in importance on field grown tomato crops. Expand
Molecular Support for Species Status of the Nazca Booby (Sula granti)
Compared sequence variation in the mitochondrial cytochrome-b gene among 75 Nazca Boobies and 37 Masked Booby representing three subspecies from the central and eastern Pacific and Atlantic oceans indicated strong differentiation of cytochrom-b variation among taxa. Expand
Initial events in the colonisation of tomatoes by Oidium lycopersici, a distinct powdery mildew fungus of Lycopersicon species
The rDNA intergenic spacer sequence of Oidium lycopersici was determined and compared with the sequences of other powdery mildew fungi found on tomato, but it exhibited a close similarity to Erysiphe aquilegiae var. Expand
Strategy for exploiting exotic germplasm using genetic, morphological, and environmental diversity: the Aegilops tauschii Coss. example
Hexaploid bread wheat evolved from a rare hybridisation, which resulted in a loss of genetic diversity in the wheat D-genome with respect to the ancestral donor, Aegilops tauschii. Novel geneticExpand
Mathematical models for invasive species management: Grey squirrel control on Anglesey
A stochastic, spatial model is developed that represents the real habitat structure, distribution and linkage on Anglesey and the neighbouring mainland and includes the key population and epidemiological dynamics of the red-grey-squirrelpox system and has important implications for the conservation of threatened red squirrels throughout the UK and in Europe.

Blue Carbon Stocks and Cross-Habitat Subsidies
Blue carbon ecosystems (including saltmarsh, mangrove, seagrass meadows, and other soft sediment habitats) play a valuable role in aquatic carbon dynamics and contribute significantly to globalExpand
Modelling the impact of forest design plans on an endangered mammal species: the Eurasian red squirrel
The Eurasian red squirrel is under threat in the UK from the introduced North American grey squirrel. National measures to save the species include large conifer forest reserves where managementExpand
Mathematical models for red squirrel conservation
In this thesis we develop mathematical models to understand the process of ecological invasion when the invading species also carries a disease that is harmful to the native species. In particular weExpand
Enigmadiplosis agapanthi, a new genus and species of gall midge (Diptera, Cecidomyiidae) damaging Agapanthus flowers in England.
Hundreds of adult midges were reared from the Agapanthus sample by the end of September 2014 and all adults showed characters of the tribe Clinodiplosini, not Cecidomyiini, and this enigmatic combination of larval and adult characters merits description of a new species. Expand
