Sentence examples for opportunistic sampling from inspiring English sources

Opportunistic sampling may be one strategy to reduce sampling costs, but the accuracy and suitability of the assessments derived from this sampling remain yet poorly addressed, particularly in forest landscapes.

In general, opportunistic sampling was more efficient than systematic sampling, resulting in SDMs with a comparable accuracy for a lower inventory cost or in more accurate SDMs for the same sampling effort.

We conclude that opportunistic sampling along tracks may be a practical and cost-effective option for SDMs in forest landscapes, as long as the density and spatial arrangement of tracks are sufficient to cover the full range of environmental conditions.

This disparity may result, in part, from the different time scales underpinning evolutionary and ecological population structure; however, the power of previous genetic studies to elucidate population structuring has been limited by opportunistic sampling.

This was mainly because the four sampling strategies adequately captured the environmental variability of the study area, and because plots in the opportunistic sampling were located at a sufficient distance from tracks to avoid potential edge effects.

Accurate evaluation of the significance of chlamydial infections in wildlife is otherwise hampered by i) the cross-sectional nature of most impact studies, ii) a lack of standardised diagnostic approaches, iii) limited study sizes, and iv) biases associated with opportunistic sampling.

Ecologists tend to use the term "opportunistic sampling" for this approach (De Barba et al. 2010).

If the sample success rate is extremely low or if samples are difficult to detect and/or chimpanzee density is low, genetic monitoring with opportunistic samples collected over a short period of time may not be feasible.

A theoretical sampling (professional) and opportunistic sample (participants) was proposed.

An opportunistic sample of medical schools was selected in each country.

An opportunistic sample of undergraduate students at UK universities was recruited.
