Monitoring the structure of restored forests and assessing aboveground carbon density through canopy metrics derived from digital aerial photogrammetry and LiDAR

open access: yesRestoration Ecology, EarlyView.
Monitoring forest dynamics is crucial to understanding forest succession drivers and ensuring successful restoration outcomes. Laser scanners onboard robust drone systems are valuable for penetrating forest canopies and providing structural details. With the growing accessibility to low‐cost drones equipped with advanced optical sensors, photogrammetry

Qualitative properties of the heat content

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We obtain monotonicity and convexity results for the heat content of domains in Riemannian manifolds and in Euclidean space subject to various initial temperature conditions. We introduce the notion of a strictly decreasing temperature set, and show that it is a sufficient condition to ensure monotone heat content.

Temporal field phenomics of transgenic maize events subjected to drought stress: Cross‐validation scenarios and machine learning models

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) to predict key phenotyping traits in maize (Zea mays L.) and monitor plant response to drought

The multidepot drone general routing problem with duration and capacity constraints

open access: yesInternational Transactions in Operational Research, Volume 32, Issue 6, Page 3756-3779, November 2025.
Abstract This paper studies the multidepot drone general routing problem with duration and capacity constraints (MDdGRP), an extension of the classical general routing problem with several depots. A fleet of drones with limited flight time and payload, each one located in a different depot, must jointly perform the service.

Low Heat Flow in the Anhydros Basin, Aegean Sea, Recorded by Deep Subsurface Temperatures

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Subseafloor in situ temperatures in a drilled hole in the Anhydros Basin, Aegean Sea, measured during International Ocean Discovery Program (IODP) Expedition 398, yielded a low heat flow (<0.023 W/m2) despite active magmatism and rifting in the region.

Two Strategies for Researching the Endangered Yangtze Finless Porpoises Suggest Data‐Poor Areas Are Worthy of Greater Conservation Efforts

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Two strategies were used to assess the abundance and distribution of Yangtze finless porpoises in the Jingjiang section of the Yangtze River to make up for the lack of knowledge about this area. These results provide support for the management and conservation of finless porpoises.

Stratified, Spatially Balanced Cluster Sampling for Cost‐Efficient Environmental Surveys

open access: yesEnvironmetrics, Volume 36, Issue 5, July 2025.
ABSTRACT Large‐scale environmental surveys relying on intensive fieldwork are expensive, but survey sampling methodology offers several options to improve their cost‐efficiency. For example, sites selected for field assessments can be arranged in clusters to reduce the time spent moving between the sites, and auxiliary data can be utilized to stratify ...
