Distribution and Habitat Suitability of Artemisia annua in China Under Climate Change Scenarios

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We used an optimized MaxEnt model to assess the current and future suitable habitats of Artemisia annua in China under CMIP6 climate scenarios. Suitable areas are projected to contract overall and shift northeastward, primarily constrained by winter temperature and elevation.

Georeferencing of close range photogrammetric data [PDF]

, 2011
The paper presents some general approaches for indirect georeferencing of close range photogrammetric data being acquired for various applications by the imaging systems of different types either independently or in integration. Various digital metric or

Toward Consistent Canopy Characterization From Low‐Cost UAV Imagery

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We show that UAV‐based crown segmentation can reliably characterize dominant canopy trees in a structurally complex tropical forest. Focusing on these key individuals improves the assessment of forest structure and supports ecological monitoring at multiple scales. ABSTRACT Monitoring tropical forest structure at landscape scale requires cost‐effective

UAV Data Collection Co-Registration: LiDAR and Photogrammetric Surveys for Coastal Monitoring

Drones
When georeferencing is a key point of coastal monitoring, it is crucial to understand how the type of data and object characteristics can affect the result of the registration procedure, and, above all, how to assess the reconstruction accuracy. For this

Transitioning From Rice‐Wheat to Diversified Rice‐Based Rotations Enhances Rice Production and Mitigates Greenhouse Gas Emissions Across Asia

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice‐wheat cropping systems underpin food security across Asia but also represent major sources of agricultural greenhouse gas (GHG) emissions. Replacing wheat with diversified crop species to create alternative rice‐based cropping systems may become an effective strategy for sustainable production.

Eyespots in Automeris Moths Mimic Sympatric Owl Species (Lepidoptera: Saturniidae)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Eyespot mimicry is a common anti‐predator strategy in moths, yet the mechanism underlying its effectiveness in Automeris remains unresolved. Using species distribution models, convolutional neural networks, and saliency mapping, we show that Automeris eyespots are visually confusable with sympatric owl eyes and that this similarity is concentrated in ...

Georeferencing in QGIS 2.0

, 2013
In this lesson, you will learn how to georeference historical maps so that they may be added to a GIS as a raster layer. Georeferencing is required for anyone who wants to accurately digitize data found on a paper map, and since historians work mostly in

Surface grain-size mapping of braided channels from SfM photogrammetry [PDF]

Earth Surface Dynamics
Braided channels are known as fluvial systems with a high heterogeneity of physical conditions, resulting from particularly active interacting processes of coarse sediment sorting and transport.
