Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

A Hybrid Framework for Stock Price Forecasting Using Metaheuristic Feature Selection Approaches and Transformer Models Enhanced by Temporal Embedding and Attention Pruning

Applied AI Letters, Volume 7, Issue 1, February 2026.
Workflow of the proposed hybrid BWO‐Transformer framework for stock price prediction. ABSTRACT Accurately predicting stock prices remains a major challenge in financial analytics due to the complexity and noise inherent in market data. Feature selection plays a critical role in improving both computational efficiency and predictive performance. In this

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline
