From ODE to Open Markov Chains, via SDE: an application to models for infections in individuals and populations

Computational and Mathematical Biophysics, 2020
We present a methodology to connect an ordinary differential equation (ODE) model of interacting entities at the individual level, to an open Markov chain (OMC) model of a population of such individuals, via a stochastic differential equation (SDE ...

The interplay between landscape change and plasticity in habitat selection determines dispersal movements and settlement in small non‐flying vertebrates

Oikos, Volume 2026, Issue 5, May 2026.
The response of dispersers to landscape changes depends on both external environmental conditions and individual internal conditions, as well as movement and orientation abilities. Plasticity in habitat selection may also affect how individuals respond to landscape changes.

On coupled systems of Hammerstein integral equations

Boundary Value Problems, 2019
In this paper we deal with generalized coupled systems of integral equations of Hammerstein type with nonlinearities depending on several derivatives of both variables and we underline that both equations and both variables can have a different ...

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

Journal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Two P or Not Two P: Mendel Random Variables in Combining Fake and Genuine p-Values

AppliedMath
The classical tests for combining p-values use suitable statistics T(P1,…,Pn), which are based on the assumption that the observed p-values are genuine, i.e., under null hypotheses, are observations from independent and identically distributed Uniform(0 ...
