Survival, rarity, and extinction in tropical stony corals
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Many reef‐building tropical corals are becoming rare. We considered the meaning of rarity in corals and highlighted taxa that have reached low abundances in the last few decades. The difficulties of quantifying rarity in the marine environment arise from the sheer scale and 3‐dimensional nature of the biome and the inherent challenges therein ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Three voluminous inflated lobate lava flow complexes on the distal rifts of Axial Seamount are much larger than other known flows in the global spreading system. Each complex is 65–100 km2, is up to 130 m thick, and is ∼3.0–4.6 km3, almost 100 times the volumes of historical Axial flows.

CCFF‐Net: Cross‐Channel Feature Fusion Network for Underwater Object Detection
IET Image Processing, Volume 20, Issue 1, January/December 2026.Challenging underwater environmental conditions lead to severe degradation of underwater images, such as intensity attenuation and colour distortion. This issue causes incomplete feature representation of underwater objects, posing difficulties to state‐of‐the‐art detectors.

Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems
IET Optoelectronics, Volume 20, Issue 1, January/December 2026.The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...
