Rejection of Schmidt et al.'s estimators for bear population size

Ecology and Evolution, 2019
Aerial distance sampling of bears to estimate population size has been used throughout many parts of Alaska. The distance sampling models are complex since they need to account for undetected bears and differences in detection probabilities.

Towards the mother-of-all-models: customised construction of the mark-recapture likelihood function [PDF]

Animal Biodiversity and Conservation, 2004
With a proliferation of mark–recapture models and studies collecting mark–recapture data, software and analysis methods are being continually revised. We consider the construction of the likelihood for a general model that incorporates all the features ...

An evaluation of population indices for northern bobwhite

Wildlife Society Bulletin, 2019
Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...

Home‐site fidelity and homing behavior of the big‐headed turtle Platysternon megacephalum

Ecology and Evolution, 2021
Site fidelity refers to the restriction of dispersal distance of an animal and its tendency to return to a stationary site. To our knowledge, the homing ability of freshwater turtles and their fidelity is reportedly very low in Asia.

Flexible and non-invasive passive integrated transponder (PIT) tagging protocols for tropical freshwater fish species

MethodsX, 2018
Passive integrated transponder (PIT) tagging has proven to be an effective mark-recapture technique for many temperate freshwater and marine fish species, but its adaptability to tropical freshwater species remains largely unknown.
