The Range‐Resident Logistic Model: A New Framework to Formalise the Population‐Dynamics Consequences of Range Residency

open access: yesEcology Letters, Volume 28, Issue 12, December 2025.
We introduce the range‐resident logistic model, an extension of the spatial logistic model that incorporates empirically supported range‐resident movement, showing that neglecting range residency can lead to under‐ or overestimating population carrying capacity.

Population Structure Plays a Key Role in Community Stability

open access: yesEcology Letters, Volume 28, Issue 12, December 2025.
Population structure is a widespread yet underappreciated feature of ecological communities. Here, we develop a general theoretical framework integrating life‐stage structure into community matrix models and show that stage‐specific interactions—especially asymmetric predator‐prey dynamics—can fundamentally alter stability outcomes. Our findings reveal

Solution of the Nonlinear Mixed Volterra-Fredholm Integral Equations by Hybrid of Block-Pulse Functions and Bernoulli Polynomials

open access: yesThe Scientific World Journal, 2014
A new numerical method for solving the nonlinear mixed Volterra-Fredholm integral equations is presented. This method is based upon hybrid functions approximation.

Solution of fractional Volterra–Fredholm integro-differential equations under mixed boundary conditions by using the HOBW method

open access: yesAdvances in Differential Equations, 2019
A new approximate technique is introduced to find a solution of FVFIDE with mixed boundary conditions. This paper started from the meaning of Caputo fractional differential operator. The fractional derivatives are replaced by the Caputo operator, and the

Exponential Convergence for Numerical Solution of Integral Equations Using Radial Basis Functions

open access: yesJournal of Applied Mathematics, 2014
We solve some different type of Urysohn integral equations by using the radial basis functions. These types include the linear and nonlinear Fredholm, Volterra, and mixed Volterra-Fredholm integral equations.
