Melon‐Headed Whale (Peponocephala electra) Occurrence in the Equatorial Mid‐Atlantic Ocean With Descriptions of Their Whistles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Acoustic studies for any cetacean species in tropical Atlantic Ocean waters are scarce, especially for oceanic dolphins, such as the melon‐headed whale, Peponocephala electra. Here we describe a unique visual and acoustic record for this species, filling an information gap about the acoustic patterns of these delphinids in this part of the ...

A Trojan horse inside the gates: Alien–native mating interactions in mixed populations of Solidago taxa

Plant Biology, Volume 28, Issue 1, Page 261-271, January 2026.
DAPI flow cytometry identified post‐invasion processes—hybridisation, introgression, and polyploidization—in mixed populations of Solidago canadensis, S. virgaurea and S. ×niederederi. Abstract The establishment and possible impacts of alien–native hybrids depend on their formation frequency and ability to spread using generative and vegetative ...

Study on the Characteristics of Surface Subsidence Induced by the Construction of a Subsurface Karst Tunnel Beneath an Airport

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The tunnels in Southwest China are located in environmentally sensitive areas with intensive karst development and close proximity to airports. Surface subsidence in these regions poses serious risks to both tunnel construction safety and airport operational safety.

A Coarse‐to‐Fine 3D LiDAR Localization With Deep Local Features for Long‐Term Robot Navigation in Large Environments

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
The location of a robot is a key aspect in the field of mobile robotics. This problem is particularly complex when the initial pose of the robot is unknown. In order to find a solution, it is necessary to perform a global localization. In this paper, we propose a method that addresses this problem using a coarse‐to‐fine solution.
