He thereupon proceeded to supplement his avifaunal survey with a shotgun sampling, undertaken by himself and several natives whom he engaged, that yielded four hundred and thirty-two specimens.
The unbiased sampling undertaken allowed us to compare the same forest vegetation characteristics at two levels of compositional resolution across local, regional and national scales.
Simulated sampling undertaken in a parallel research effort suggests that the overestimation of the SEs was probably much larger for the ALS-based estimates compared to the NFI estimates.
Sample sites were around the entire circumference of Osprey Reef but with 92% of sampling undertaken at the Entrance site (Fig. 1).
We consider that these declines in prevalence and concentration are likely to be representative of the situation in north-western India because of the wide distribution of sampling sites and scale of sampling undertaken (>4,500 carcass samples analysed in T1 – T3).
This was a quantitative, exploratory, cross-sectional study with convenience sampling, undertaken during November 2011 to January 2012.
The demographic characteristics of those agreeing to take part were determined and further targeted sampling undertaken to ensure the study sample remained representative.
Further confirmation that X. laevis was absent from the angling pond was provided by the 'continuous sampling' undertaken by anglers: no captures were reported up to late 2014.
