Persistent border: an analysis of the geographic boundary of an intertidal species (2009)
Herbert, R.J.H., Southward, A.J., Clarke, R.T., Sheader, M., Hawkins, S.J.
The biological performance of species close to their biogeographic boundaries is of critical interest in a period of rapid climate change and can inform predictions of future patterns of...
Hydrological prediction in a non-stationary world (2007)
The paper discusses evidence that common assumptions in the analysis of hydrological time series (homogeneous variability in random fluctuations about a constant mean value) may not be appropriate...

Timing System Design Considerations for a Mobile Astrolabe, (2005)
Lukac,C. F., Wheeler,P. J., Keating,R. E., Clarke,R. T.
The Danjon Astrolabe at the naval Observatory has been traditionally used to determine Universal Time and improve the systematic accuracy of star positions. During the past year, it has been used to...

Fitting and testing the significance of linear trends in Gumbel-distributed data (2002)
The widely-used hydrological procedures for calculating events with T-year return periods from data that follow a Gumbel distribution assume that the data sequence from which the Gumbel distribution...

Attachment of the ciliate Epidinium Crawley to plant fragments in the sheep rumen.
High concentrations of the ciliate Epidinium Crawley are associated with damaged regions of fresh plant material undergoing digestion in the sheep rumen. This finding supports that postulate that...

Thomas, J A, Bourn, N A, Clarke, R T, Stewart, K E, Simcox, D J, Pearman, G S, ...
Habitat quality and metapopulation effects are the main hypotheses that currently explain the disproportionate decline of insects in cultivated Holarctic landscapes. The former assumes a degradation...
The effects of spatial patterns in habitat quality on community dynamics within a site
Clarke, R. T., Thomas, J. A., Elmes, G. W., Hochberg, M. E.
Metapopulation studies of single species have shown that the size and spatial arrangement of patches of assumed uniformly 'suitable' habitat can influence their population dynamics and persistence....
Extreme host specificity by Microdon mutabilis (Diptera: Syrphiae), a social parasite of ants
Elmes, G. W., Barr, B., Thomas, J. A., Clarke, R. T.
Larvae of the syrphid fly Microdon mutabilis are social parasites which live up to two years, feeding on ant brood in nests of Formica lemani ants. We questioned why M. mutabilis is extremely...
