Foraging ecology of hoverflies: morphology of the mouthparts in relation to feeding on nectar and pollen in some common urban species
- F. Gilbert
- Environmental Science
- 1 August 1981
The feeding behaviour of hoverflies (Diptera: Syrphidae) is compared with field observations to find patterns that correspond with previous accounts of the feeding behaviour.
Phylogeny of Palaearctic Syrphidae (Diptera): evidence from larval stages
- G. Rotheray, F. Gilbert
- Biology
- 1 September 1999
The phylogeny of Palaearctic Syrphidae was estimated using 187 larval morphological characters obtained from about 65% of the fauna and based the analysis at the generic level and a key to genera using larval characters are provided.
The Evolution of Imperfect Mimicry
- F. Gilbert
- Biology
- 2005
This chapter outlines the basic ideas of mimicry theory, and shows how they fail to account for the commonly imperfectly mimetic patterns of the main taxonomic group in the Holarctic that contains mimics; the hoverflies (Diptera, Syrphidae).
The Natural History of Hoverflies
- G. Rotheray, F. Gilbert
- Environmental Science
- 2011
Hoverflies are one of the few insect groups with a growing appeal but with no book devoted to their natural history, this book is to fill this gap and to take readers into the world of hoverflies by giving an account of their major features, attributes, habits and behaviour.
Corridors maintain species richness in the fragmented landscapes of a microecosystem
- F. Gilbert, Andrew Gonzalez, Isabel Evans-Freke
- Environmental ScienceProceedings of the Royal Society of London…
- 7 April 1998
Using moss patches as model microecosystems, this work provides probably the first field experimental test of the idea that corridors can reduce the rate of loss of species, and therefore help to maintain species richness.
Climate‐based models of spatial patterns of species richness in Egypt’s butterfly and mammal fauna
- T. Newbold, F. Gilbert, S. Zalat, Ahmed El‐Gabbas, T. Reader

It is suggested that climate-based models of species richness could provide a rapid method for selecting potential areas for protection and thus have important implications for biodiversity conservation.
Helminth infections in Apodemus sylvaticus in southern England: interactive effects of host age, sex and year on the prevalence and abundance of infections
- J. Behnke, J. Lewis, S. N. Zain, F. Gilbert
- BiologyJournal of Helminthology
- 1 January 1999
The patterns of between-year variations in the prevalence and abundance of infection were different for each of the six species for which sufficient quantitative data were available to enable statistical analysis.
Phylogeny of Syrphidae (Diptera) inferred from combined analysis of molecular and morphological characters
- G. Ståhls, H. Hippa, G. Rotheray, J. Muona, F. Gilbert
- Biology
- 1 October 2003
The results support at least two independ- ent origins of entomophagy in syrphids, and frequent shifts between larval feeding habitats within the saprophagous eristalines.
The phylogeny and systematics of European predacious Syrphidae (Diptera) based on larval and puparial stages
- G. Rotheray, F. Gilbert
- Biology
- 1989
Interpretation of the cladogram suggests that, within Syrphinae, a system of five tribes can be recognized and that a major trend has been a shift from ground layer to arboreal larval habitats, with an increasing degree of obligate dependence on soft-bodied Homoptera as prey.
The equilibrium theory of island biogeography : fact or fiction?
- F. Gilbert
- Environmental Science
- 1 September 1980
It is concluded that there is little support for its tenets and the application of the equilibrium theory of island biogeography to nature conservation and ecology is therefore premature.
