Keep Your Distance: Determining Sampling and Distance Thresholds in Machine Learning Monitoring
, 2022 Machine Learning~(ML) has provided promising results in recent years across different applications and domains. However, in many cases, qualities such as reliability or even safety need to be ensured. To this end, one important aspect is to determine whether or not ML components are deployed in situations that are appropriate for their application ...

Domestic Cat Abundance and Activity Across a Residential Land Use Gradient
Frontiers in Ecology and Evolution, 2021 Free-ranging domestic cats are a detriment to wildlife and humans by preying on native species and transmitting disease. As a result, removing free-ranging cats from the landscape has become a conservation and public health priority.

Distance Sampling Detection Functions: 2D or Not 2D? [PDF]
Biometrics, 2016 SummaryConventional distance sampling (CDS) methods assume that animals are uniformly distributed in the vicinity of lines or points. But when animals move in response to observers before detection, or when lines or points are not located randomly, this assumption may fail.

Remote Sensing, 2022 Conservation of wildlife depends on precise and unbiased knowledge on the abundance and distribution of species. It is challenging to choose appropriate methods to obtain a sufficiently high detectability and spatial coverage matching the species ...

The effect of a multi-target protocol on cetacean detection and abundance estimation in aerial surveys [PDF]
Royal Society Open Science, 2019 A double-platform protocol was implemented in the Bay of Biscay and English Channel during the SCANS-III survey (2016). Two observation platforms using different protocols were operating on board a single aircraft: the reference platform (Scans ...

The unmarked R package: Twelve years of advances in occurrence and abundance modelling in ecology
Methods in Ecology and Evolution, 2023 Species distribution models (SDMs) are widely applied to understand the processes governing spatial and temporal variation in species abundance and distribution but often do not account for measurement errors such as false negatives and false positives ...

The number and distribution of polar bears in the western Barents Sea
Polar Research, 2017 Polar bears have experienced a rapid loss of sea-ice habitat in the Barents Sea. Monitoring this subpopulation focuses on the effects on polar bear demography.

Urban birds in the Sonoran Desert: estimating population density from point counts
Huitzil, 2015 We conducted bird surveys in Hermosillo, Sonora using distance sampling to characterize detection functions at point-transects for native and non-native urban birds in a desert environment.
