Biodiversity in model ecosystems, I: Coexistence conditions for competing species [PDF]
, 2005 This is the first of two papers where we discuss the limits imposed by competition to the biodiversity of species communities. In this first paper we study the coexistence of competing species at the fixed point of population dynamic equations.

Competitive coexistence of two Pneumocystis species
Infection, Genetics and Evolution, 2006 Pneumocystis are fungal pathogens of mammalian lungs that can cause lethal pneumonia in immunocompromised hosts. In some mammals, coinfections of genetically distinct Pneumocystis populations have been identified, but the nature of their interaction and its significance are unknown.

Nonequilibrium critical behavior of a species coexistence model
, 2006 A biologically motivated model for spatio-temporal coexistence of two competing species is studied by mean-field theory and numerical simulations. In d>1 dimensions the phase diagram displays an extended region where both species coexist, bounded by two ...

Mobility and asymmetry effects in one-dimensional rock-paper-scissors games
, 2010 As the behavior of a system composed of cyclically competing species is strongly influenced by the presence of fluctuations, it is of interest to study cyclic dominance in low dimensions where these effects are the most prominent.

Frontiers in Ecology and EvolutionBiological invasions can lead to changes in the interspecific association and coexistence patterns of plant species; however, the differences in the interspecific association characteristics of invaded plant communities in heterogeneous habitats and ...

Ecosphere, 2023 Ecological theory posits that higher species richness should be associated with greater exploitation of resources and niche packing resulting from either increasing species niche overlap or specialization of species' niches.

Nonlinear Dynamics of the Rock-Paper-Scissors Game with Mutations
, 2015 We analyze the replicator-mutator equations for the Rock-Paper-Scissors game. Various graph-theoretic patterns of mutation are considered, ranging from a single unidirectional mutation pathway between two of the species, to global bidirectional mutation ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A signal of competitive dominance in mid-latitude herbaceous plant communities
Royal Society Open Science, 2021 Understanding the main determinants of species coexistence across space and time is a central question in ecology. However, ecologists still know little about the scales and conditions at which biotic interactions matter and how these interact with the ...

Feasibility and coexistence of large ecological communities [PDF]
, 2017 The role of species interactions in controlling the interplay between the stability of ecosystems and their biodiversity is still not well understood. The ability of ecological communities to recover after small perturbations of the species abundances ...
