TreeSegAgent: Agentic tree instance segmentation via a multi‐anchor pipeline

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Individual‐tree segmentation from three‐dimensional forest point clouds underpins forest inventory, biomass estimation and ecosystem monitoring, but remains challenging in structurally complex stands, where vertical heterogeneity and point‐density degradation weaken the robustness of centre‐offset‐based instance grouping.

An AI‐based and coding‐free integration for forest Leaf Area Index calculation

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Seasonal and spatial variations in Leaf Area Index (LAI, or plant area index, PAI) are challenging to delineate in tropical forests because the changes are often too subtle to be reliably detected. Many existing DHP software tools offer one‐click processing of all images using auto‐threshold segmentation (e.g.

Genomic Assessment of Reintroduced African Wild Dogs Informs Conservation Translocations

open access: yesAnimal Conservation, EarlyView.
Few reintroduction and translocation programs incorporate genomic assessments into management planning, despite ongoing debate over how founder individuals should be selected. Here, we assess the genomic composition of reintroduced African wild dog (Lycaon pictus) populations in private reserves in South Africa, comparing them with a free‐roaming ...

Opium Cultivation Imperilling Endangered Species in Northern Laos

open access: yesAnimal Conservation, EarlyView.
To avoid government eradication efforts, farmers in northeastern Laos shifted opium cultivation deep into a national park, causing a > 1000% increase in protected forest cleared for the crop between 2018 and 2022. This displacement directly threatened endangered species like white‐cheeked gibbons, elephants, and dholes by causing a rise in hunting ...
