Enabling High-Resolution Wildlife Tracking: A novel antenna beam-based approach including per-position error estimations for Automated Radiotelemetry Systems Open
Background The increasing importance of wildlife movement data in ecology and conservation has fueled the development of Automated Radiotelemetry Systems (ARTS) using very-high-frequency (VHF) transmitters. To make optimal use of this data…

Leveraging readily available heterogeneous LiDAR data to enhance modeling of successional stages at tree species level in temperate forests Open
In the context of the ongoing biodiversity crisis, understanding forest ecosystems, their tree species composition and especially the successional stages of their development is crucial. They collectively shape the biodiversity within fore…

The devil is in the detail: Environmental variables frequently used for habitat suitability modeling lack information for forest‐dwelling bats in Germany Open
In response to the pressing challenges of the ongoing biodiversity crisis, the protection of endangered species and their habitats, as well as the monitoring of invasive species are crucial. Habitat suitability modeling (HSM) is often trea…

Nature 4.0: A networked sensor system for integrated biodiversity monitoring Open
Ecosystem functions and services are severely threatened by unprecedented global loss in biodiversity. To counteract these trends, it is essential to develop systems to monitor changes in biodiversity for planning, evaluating, and implemen…

<i>spatialMaxent</i>: Adapting species distribution modeling to spatial data Open
Conventional practices in species distribution modeling lack predictive power when the spatial structure of data is not taken into account. However, choosing a modeling approach that accounts for overfitting during model training can impro…

Towards reliable estimates of abundance trends using automated non‐lethal moth traps Open
Monitoring insect abundance or species richness at high spatial and temporal resolution is difficult due to personnel, maintenance, and post‐processing costs as well as ethical considerations. Non‐invasive automated insect monitoring syste…

Classifying the activity states of small vertebrates using automated <span>VHF</span> telemetry Open
The most basic behavioural states of animals can be described as active or passive. While high‐resolution observations of activity patterns can provide insights into the ecology of animal species, few methods are able to measure the activi…

Automated non-lethal moth traps can be used for robust estimates of moth abundance Open
Recent reports of insect decline highlight the need for extensive large-scale insect monitoring. However, obtaining abundance or species richness data at high spatial and temporal resolution is difficult due to personnel, maintenance, and …

Introduction of an automatic and open‐source radio‐tracking system for small animals Open
Movement ecology of small wild animals is often reliant on radio‐tracking methods due to the size and weight restrictions of available transmitters. In manual radio telemetry, large errors in spatial position and infrequent relocations pre…
