Accounting for imperfect detection of groups and individuals when estimating abundance

Ecology and Evolution, 2017
If animals are independently detected during surveys, many methods exist for estimating animal abundance despite detection probabilities

Camera traps placed to detect predators underestimate prey densities

Oryx
Mountain ungulates play an important role in ecosystems as primary consumers and as prey for rare predators. Monitoring their populations is therefore critical for conservation efforts.

Abundance Estimation Using Minimum Order Set Distances in Line Transect Sampling

Stats
Line transect sampling is widely used for estimating population abundance, but existing nonparametric estimators of detection density at the transect line often suffer from boundary bias and tuning sensitivity. In this paper, we propose two simple tuning-
