  • Telford, Richard J.; Vandvik, Vigdis; Birks, Harry John Betteley (Peer reviewed; Journal article, American Association for the Advancement of Science, 2006)
    In contrast with macroorganisms, whose geographical ranges are typically restricted, many microbial species appear to have cosmopolitan distributions. This observation has been explained as a consequence of ubiquitous ...
  • Telford, Richard J.; Birks, Harry John Betteley (Peer reviewed; Journal article, Springer, 2011-04-27)
    We investigate the effect that uneven sampling of the environmental gradient has on transfer-function performance using simulated community data. We find that cross-validated estimates of the root mean squared error ...
  • Telford, Richard J.; Heegaard, Einar; Birks, Harry John Betteley (Journal article; Peer reviewed, Arnold Publishers, 2004)
    Intercept-based methods of generating a point estimate of a calibrated radiocarbon date are very popular, but exhibit undesirable behaviour. They are highly sensitive to the mean of the radiocarbon date and to adjustments ...
  • Telford, Richard J.; Birks, Harry John Betteley; Saros, Jasmine E.; Hazewinkel, Roderick R. O.; Perren, Bianca B.; Saulnier-Talbot, Émilie; Wolfe, Alexander P. (Peer reviewed; Journal article, Public Library of Science, 2010-04-02)
    Background Although arctic lakes have responded sensitively to 20th-century climate change, it remains uncertain how these ecological transformations compare with alpine and montane-boreal counterparts over the same ...
  • Heegaard, Einar; Birks, Harry John Betteley; Telford, Richard J. (Peer reviewed; Journal article, SAGE, 2005)
    We present a procedure for estimating age-depth relationships in stratigraphical sequences by means of a generalized mixed-effect regression using an ancillary function for the partitioning of the fixed effect and the ...
  • Telford, Richard J.; Vandvik, Vigdis; Birks, Harry John Betteley (Peer reviewed; Journal article, American Association for the Advancement of Science, 2007)
    Pither argues that the relationship we found between regional species-richness maxima and modal lake-pH is expected because both values are constrained by the regional pH range and therefore cannot be interpreted as a ...
