Sample Out-of-Sample Inference Based on Wasserstein Distance [PDF]
Operations Research, 2021 Financial institutions make decisions according to a model of uncertainty. At the same time, regulators often evaluate the risk exposure of these institutions using a model of uncertainty, which is often different from the one used by the institutions. How can one incorporate both views into a single framework? This paper provides such a framework. It

A semi‐automated camera trap distance sampling approach for population density estimation
Remote Sensing in Ecology and Conservation, 2023 Camera traps have become important tools for the monitoring of animal populations. However, the study‐specific estimation of animal detection probabilities is key if unbiased abundance estimates of unmarked species are to be obtained.

Modelling density surfaces of intraspecific classes using camera trap distance sampling
Methods in Ecology and Evolution, 2023 Spatially explicit densities of wildlife are important for understanding environmental drivers of populations, and density surfaces of intraspecific classes allow exploration of links between demographic ratios and environmental conditions.

Free-Roaming Dog Surveys in Quito, Ecuador: Experiences, Lessons Learned, and Future Work
Frontiers in Veterinary Science, 2021 The selection of a survey method of free-roaming dog populations should be based on analyses of local capacities and management priorities. Here, we compare the results of surveys of the stray dog population in Quito, Ecuador, using two different ...

A method for estimating songbird abundance with drones
Drone Systems and Applications, 2022 Using drones to conduct airborne bioacoustics surveys is a potentially useful new way to estimate the abundance of vocal bird species. Here we show that by using two audio recorders suspended from a quadcopter drone it is possible to estimate distances ...

Long‐term monitoring of wildlife populations for protected area management in Southeast Asia
Conservation Science and Practice, 2022 Long‐term monitoring of biodiversity in protected areas (PAs) is critical to assess threats, link conservation action to species outcomes, and facilitate improved management. Yet, rigorous longitudinal monitoring within PAs is rare.
