A practical guide to characterising ecological coexistence. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Coexistence is simultaneously one of the most fundamental concepts of ecology, and one of the most difficult to define. A particular challenge is that, despite a well‐developed body of research, several different schools of thought have developed over the past century, leading to multiple independent, and largely isolated, branches of ...

Fluctuating Growth Rates Link Turnover and Unevenness in Species-Rich Communities. [PDF]

Ecol Lett
Through a minimal model of ecological community dynamics, we explain how the interplay between environmental stochasticity, intra‐ and interspecific competition and dispersal relates to the maintenance of diversity, the commonness of rarity and compositional turnover.

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

Oikos, EarlyView.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

Oikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

Generalized graphical mixed models connect ecological theory with widely used statistical models

Methods in Ecology and Evolution, EarlyView.
Abstract Ecological dynamics are often analysed across multiple sites, times, and variables. Ecologists typically represent interactions across space, time, and variables using generalized linear mixed models (GLMMs), generalized additive models (GAM), and structural equation models (SEM).

A Dynamical Model for the Shallow‐to‐Deep Transition of Amazonian Moist Atmospheric Convection

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The development of deep convection and the timing of storm convection initiation over land are generally poorly represented by weather and climate models, probably due to the poor representation of the interaction between shallow and deep convection.

ADVANCING LOTKA-VOLTERRA SYSTEM SIMULATION WITH VARIABLE FRACTIONAL ORDER CAPUTO DERIVATIVE FOR ENHANCED DYNAMIC ANALYSIS

Journal of Applied Analysis & Computation
Summary: This study investigates the application of the Caputo derivative with a variable fractional order to time-dependent models of Ordinary Differential Equations (ODEs), aiming to enhance the simulation accuracy of dynamic systems characterized by complex, nonlinear temporal behaviors.

Numerical Parameter‐Space Studies of Various Types of Thundercloud Gamma‐Ray Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Until recently, mainly two types of hard radiation were observed in thunderstorms: intensive, short‐lived terrestrial gamma‐ray flashes (TGFs) and weak, long‐lasting gamma‐ray glows (GRGs). The Airborne Lightning Observatory for Fly's Eye GLM Simulator and TGFs (ALOFT, GLM: Geostationary Lightning Mapper) flight campaign revealed additional ...

Fields of rational constants of cyclic factorizable derivations

Electronic Journal of Differential Equations, 2015
We describe all rational constants of a large family of four-variable cyclic factorizable derivations. Thus, we determine all rational first integrals of their corresponding systems of differential equations.

Modeling species co‐occurrence effects to inform invasive barred owl management and recovery of the northern spotted owl

Ecological Applications, Volume 36, Issue 2, March 2026.
Abstract Robust estimation of wildlife populations represents a cornerstone of wildlife research and provides critical information to guide management, including identifying at‐risk species, setting harvest rates, and evaluating predator and invasive species control programs.
