Deer Behavior Affects Density Estimates With Camera Traps, but Is Outwighted by Spatial Variability
Henrich, Maik; Hartig, Florian; Dormann, Carsten F.; Kühl, Hjalmar S.; Peters, Wibke; Franke, Frederik; Peterka, Tomáš; Šustr, Pavel; Heurich, Marco Dietmar (Peer reviewed; Journal article, 2022)Density is a key trait of populations and an essential parameter in ecological research, wildlife conservation and management. Several models have been developed to estimate population density based on camera trapping data, ... -
Estimating effective survey duration in camera trap distance sampling surveys
Kühl, Hjalmar S.; Buckland, Stephen T.; Henrich, Maik; Howe, Eric; Heurich, Marco Dietmar (Peer reviewed; Journal article, 2023)Among other approaches, camera trap distance sampling (CTDS) is used to estimate animal abundance from unmarked populations. It was formulated for videos and observation distances are measured at predetermined ‘snapshot ... -
First-Passage Time Analysis Based on GPS Data Offers a New Approach to Estimate Restricted Zones for the Management of Infectious Diseases in Wildlife: A Case Study Using the Example of African Swine Fever
Wielgus, Elodie; Klamm, Alisa; Conraths, Franz J.; Dormann, Carsten F.; Henrich, Maik; Kronthaler, Franz; Heurich, Marco Dietmar (Peer reviewed; Journal article, 2023)An essential part of any disease containment and eradication policy is the implementation of restricted zones, but determining the appropriate size of these zones can be challenging for managers. We designed a new method, ... -
A semi-automated camera trap distance sampling approach for population density estimation
Henrich, Maik; Burgueño, Mercedes; Hoyer, Jacqueline; Haucke, Timm; Steinhage, Volker; Kühl, Hjalmar S.; Heurich, Marco Dietmar (Peer reviewed; Journal article, 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 ... -
Spatial variation in red deer density in a transboundary forest ecosystem
Tourani, Mahdieh; Franke, Frederik; Heurich, Marco Dietmar; Henrich, Maik; Peterka, Tomáš; Ebert, Cornelia; Oeser, Julian; Edelhoff, Hendrik; Milleret, Cyril Pierre; Dupont, Pierre; Bischof, Richard; Peters, Wibke Erika Brigitta (Peer reviewed; Journal article, 2023)Forests in Europe are exposed to increasingly frequent and severe disturbances. The resulting changes in the structure and composition of forests can have profound consequences for the wildlife inhabiting them. Moreover, ...
