Two Schemes Based on the Collocation Method Using Müntz–Legendre Wavelets for Solving the Fractional Bratu Equation

open access: yesAxioms
Our goal in this work is to solve the fractional Bratu equation, where the fractional derivative is of the Caputo type. As we know, the nonlinearity and derivative of the fractional type are two challenging subjects in solving various equations.

Fish Assemblages Associated With Multiscale Environmental Variables in Agriculturally Impacted Streams

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Agricultural development is a global wide‐spread alteration to natural landscapes that can impact stream fish assemblages at multiple scales. Knowing how environmental variables affect stream fish diversity and abundance is important for the conservation and management of stream fish assemblages.

Convergence analysis of the Legendre wavelets method for a class of Fredholm-Volterra integro-differential equations of fractional-order

open access: yesMiskolc Mathematical Notes
In this paper, we develop a Legendre wavelets method for the numerical solution of Fredholm-Volterra integro-differential equations of fractional order. The Caputo sense is used to explain the fractional derivative operator.

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Relative Influence of Flow Regime, Natural and Anthropogenic Environment on Multidimensional Stream Fish Diversity

open access: yesEcohydrology, Volume 19, Issue 2, March 2026.
ABSTRACT The flow regime is considered a ‘master variable’ in riverine ecology because it directly influences stream geomorphology and biological communities. However, other environmental and anthropogenic factors have direct and synergistic effects with flow on fish diversity, complicating estimates of the flow regime's true importance. Moreover, most

Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests

open access: yesEcology, Volume 107, Issue 3, March 2026.
Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

The Use of the Legendre Transform in Chemical Thermodynamics: A Powerful Tool

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 2, March 2026.
Starting from Gibbs’ formulation of internal energy, all thermodynamic potentials can be obtained via the Legendre transform, along with a mnemonic rule for their calculation and an analysis of the extensivity of internal energy, culminating in Euler's theorem, the Gibbs–Duhem equation, and the definition of chemical potential.
