Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Lidar‐Based Object Tracking of Traffic Participants with Sensor Nodes in Existing Urban Infrastructure

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
This paper presents a lidar‐based sensor node design and a rule‐based state observer for edge‐based traffic participant tracking. Unlike other state‐of‐the‐art methods, this state observer enables real‐time, CPU‐only edge processing without relying on machine learning approaches.

MaxEnt Projections of Climate‐Driven Distribution Shifts for Daphniphyllum calycinum in China

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using an optimized MaxEnt model, this study projects climate‐driven distribution shifts of Daphniphyllum calycinum, an ecologically and medicinally important subtropical tree in China. Results reveal that annual mean temperature and dry season precipitation primarily govern its distribution, with future warming scenarios projecting significant habitat ...

Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Multi-Epoch Robust DI-Optimal Ground Control Point Network Design for Georeferencing of Google Earth Imagery

Geomatics
Ground Control Points (GCPs) are essential for accurate georeferencing of optical imagery; however, their selection is often heuristic and affected by temporal changes in image geometry.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Prospects for Complete DNA Barcode Coverage of the New Zealand Insect Fauna

Journal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
The accurate identification of insects supports conservation, biosecurity and ecological monitoring. However, morphological identification is constrained by taxonomic complexity, undescribed diversity, and limited expertise. DNA barcoding can alleviate some of these challenges and complement morphological identification, if reference data are ...
