Survival, rarity, and extinction in tropical stony corals

open access: yesConservation 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 ...

Mellin Transforms on Binary Fields

open access: yesApplied and Computational Harmonic Analysis, 2000
Some boundedness and inversion results are proved for a large class of operators on binary fields, i.e., on 2-series and 2-adic fields. As a special case, it is obtained, that the Mellin transform on any binary field can be extended to a bounded linear isometry on \(L_2\).

Factors Influencing Species Distribution Model Performance in Tropical Reef Fishes

open access: yesDiversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Reliable biodiversity assessments using species distribution models (SDMs) are essential for effective conservation and management. Understanding factors influencing SDM performance is crucial for improving model reliability, yet such links remain underexplored in marine systems.

One-sided Variations on Tries: Path Imbalance, Climbing, and Key Sampling [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
One-sided variations on path length in a trie (a sort of digital trees) are investigated: They include imbalance factors, climbing under different strategies, and key sampling.

A Robust Reversible Watermarking Algorithm Resistant to Geometric Attacks Based on Tchebichef Moments

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.
