Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity
Molecular Ecology Resources, Volume 26, Issue 2, February 2026.ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Can Umbral and q-calculus be merged? [PDF]
, 2019 The q-calculus is reformulated in terms of the umbral calculus and of the associated operational formalism. We show that new and interesting elements emerge from such a restyling. The proposed technique is applied to a different formulations of q special

A Family of Hybrid Functions Generated by the Composition of Bessel and Mittag–Leffler Functions
Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, we employ a symbolic technique to introduce a new family of Mittag–Leffler–Bessel functions (MLBFs), formed by compositionally combining the classical Bessel functions of the first kind with the three‐parameter Mittag–Leffler function.

On the ψ− Sheffer F− Polynomials and Their Degenerate Matrices
Journal of Mathematics, Volume 2026, Issue 1, 2026.In this study, we systematically construct a novel framework within umbral calculus by integrating the structures of generalized F‐calculus and degenerate sequences. Utilizing Roman’s foundational approach to umbral calculus, we first introduce a new family of ψ − F− linear functionals and their corresponding ψ − F− differential operators on the ...

On Randomised Strategies in the $λ$-Calculus [PDF]
, 2018 International audienceIn this work we study randomised reduction strategies-a notion already known in the context of abstract reduction systems-for the λ-calculus. We develop a simple framework that allows us to prove a randomised strategy to be positive

Metabolic traits and thresholds to inform marine ecological conservation and restoration
Journal of Applied Ecology, Volume 62, Issue 6, Page 1350-1363, June 2025.Integrating organismal responses to environmental stressors into monitoring protocols can provide early warning indicators of ecosystem health. This approach strengthens conservation and restoration initiatives, supporting policy decisions in the face of increasing coastal development and climate change.

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?
Journal of Animal Ecology, Volume 93, Issue 9, Page 1338-1350, September 2024.Sexual dimorphism in coadaptive host–parasite relationships are poorly understand. The comparative nature of the presented studied as well as the generalisation of the results for the geographic region sampled makes this study of general interest of ecologists, evolutionary biologists, physiologist and parasitologist, among others.

, 2021 Recently, Kim-Kim introduced the lambda-umbral calculus, in which the lambda-Sheffer sequences occupy the central position. In this paper, we introduce the fully degenerate Bell and the fully degenerate Dowling polynomials, and investigate some ...

Higher-Order Pattern Complement and the Strict λ-Calculus
, 2003 We address the problem of complementing higher-order patterns without repetitions of existential variables. Differently from the first-order case, the complement of a pattern cannot, in general, be described by a pattern, or even by a finite set of ...
