Coexistence of Two Closely Related Cyprinid Fishes (Hemiculter bleekeri and Hemiculter leucisculus) in the Upper Yangtze River, China

Diversity, 2020
Species coexistence is one of the most important concepts in ecology for understanding how biodiversity is shaped and changed. In this study, we investigated the mechanism by which two small cyprinid fishes (H. leucisculus and H.

Species competition: coexistence, exclusion and clustering [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009
We present properties of Lotka–Volterra equations describing ecological competition among a large number of interacting species. First we extend previous stability conditions to the case of a non-homogeneous niche space, i.e. that of a carrying capacity depending on the species trait.

Effective Resource Competition Model for Species Coexistence [PDF]

Physical Review Letters, 2021
Local coexistence of species in large ecosystems is traditionally explained within the broad framework of niche theory. However, its rationale hardly justifies rich biodiversity observed in nearly homogeneous environments. Here we consider a consumer-resource model in which a coarse-graining procedure accounts for a variety of ecological mechanisms and

Rapid evolution promotes fluctuation‐dependent species coexistence [PDF]

, 2021
Recent studies have demonstrated that rapid contemporary evolution can play a significant role in regulating population dynamics on ecological timescales.

Pollinator‐mediated plant coexistence requires high levels of pollinator specialization

Ecology and Evolution, 2023
In pollen‐limited plant communities, the foraging behavior of pollinators might mediate coexistence and competitive exclusion of plant species by determining which plants receive conspecific pollen. A key question is whether realistic pollinator foraging

Dynamical Mechanism for Coexistence of Dispersing Species [PDF]

Journal of Theoretical Biology, 2001
Dispersal of organisms may play an essential role in the coexistence of species. Recent studies of the evolution of dispersal in temporally varying environments suggest that clones differing in dispersal rates can coexist indefinitely. In this work, we explore the mechanism permitting such coexistence for a model of dispersal in a patchy environment ...

Soil vs. canopy seed storage and plant species coexistence in species-rich Australian shrublands

, 2007
The fire-prone shrublands of southwestern Australia are renowned for their high plant species diversity and prominence of canopy seed storage (serotiny).

Temporal mortality-colonization dynamic can influence the coexistence and persistence patterns of cooperators and defectors in an evolutionary game model [PDF]

Computational Ecology and Software, 2014
In the present report, the coexistence and persistence time patterns of Prisoners' Dilemma game players were explored in 2D spatial grid systems by considering the impacts of the mortality-colonization temporal dynamic specifically.

Species-specific traits plus stabilizing processes best explain coexistence in biodiverse fire-prone plant communities

, 2013
Coexistence in fire-prone Mediterranean-type shrublands has been explored in the past using both neutral and niche-based models. However, distinct differences between plant functional types (PFTs), such as fire-killed vs resprouting responses to fire ...

Desiccation of rock pool habitats and its influence onpopulation persistence in a Daphnia metacommunity [PDF]

, 2009
Habitat instability has an important influence on species' occurrence and community composition. For freshwater arthropods that occur in ephemeral rock pools, the most drastic habitat instabilities are droughts and the intermittent availability of water.
