We estimated measurement error (ME;) associated with 15 skeletal characters in seven
species of passerine birds. The total sample variance of the characters, from three …

The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment 1 , 2 , 3 , 4 . Such behavioural rhythms are well studied …

… step at 94C for 3 mm, 30 cycles of PCR were carried out, each cycle consisting of 30 s at
94C, 30 s at Tm in Table 1 and 30 s at 72C. Amplification products were resolved on 6 per cent …

… ground surveys here have revealed sites of global conservation importance for shorebirds,
in particular within the Gulf of Fonseca, including the Estero del Delta Real in Nicaragua (S. …

… Also, we can corroborate Studd & Robertson’s (1989) result that plumage streaking of
males measured in two successive breeding seasons neither consistently increased (nl14) nor …

We used multi-locus DNA fingerprinting to characterise the genetic mating system of the
socially monogamous yellow warbler (Dendroica petechia). Over 2 years there were no …

… The magnitudes of the mean and standard error of β geo were correlated, so we transformed
each taxon-specific β geo to Fisher’s z scale to obtain a z i value for the i th taxon [64, 65]. …

… We took advantage of natural variability in provisioning behaviour among s ordinate white-browed
scrubwrens, Sericornisfrontalis, to assess the effect of help Scrubwrens are a small …

… association, then the pattern across species seems best interpreted as a consequence of
both breeding synchrony and extra-pair mating being correlated with some other variable(s), …
