Stability and Variability in Competitive Communities
Science, 1999Long-term variability in the abundance of populations depends on the sensitivity of species to environmental fluctuations and the amplification of environmental fluctuations by interactions among species. Although competitive interactions and species number may have diverse effects on variability measured at the individual species level, a combination ...

Habitat size influences community stability
Ecology, 2021AbstractMechanisms linked to demographic, biogeographic, and food‐web processes thought to underpin community stability could be affected by habitat size, but the effects of habitat size on community stability remain relatively unknown. We investigated whether those habitat‐size‐dependent properties influenced community instability and vulnerability to

Mathematical Biosciences, 1969
Abstract The existence, uniqueness, and global stability of the stationary-state distribution of species in an ecosystem is examined on the assumption that the mode of interaction between species is nonlinear. These results extend the work of MacArthur [2], where linear interaction between species was treated.

The stability and efficiency of directed communication networks
Review of Economic Design, 2000This paper analyzes the formation of directed networks where selfinterested individuals choose with whom they communicate. The focus of the paper is on whether the incentives of individuals to add or sever links will lead them to form networks that are efficient from a societal viewpoint. It is shown that for some contexts, to reconcile efficiency with

Stability considerations in community organization
Journal of Theoretical Biology, 1979Abstract We show how mathematical stability considerations (persistence in a fluctuating environmental fluctuation) suggest that competing species should partition the habitat dimension more finely than the food-type dimension.

Stabilized precoder for indoor radio communications
IEEE Communications Letters, 2000A low complexity, stabilized precoder for broadband indoor radio is presented, which uses radial root reduction for stability, and so avoids the use of a module operator. Simulations show that the stabilized precoder has comparable performance to Tomlinson-Harashima (1971) precoding with perfect automatic gain control (AGC), and is immune to AGC ...

Communication: Antibody stability and behavior on surfaces
The Journal of Chemical Physics, 2015Antibody microarrays have the potential to revolutionize molecular detection in scientific, medical, and other biosensor applications, but their current use is limited because of poor reliability. It is hypothesized that one reason for their poor performance results from strong antibody-surface interactions that destabilize the antibody structure and ...

Biodiversity, Stability, and Productivity in Competitive Communities
The American Naturalist, 2000Three markedly different models of multispecies competition-one mechanistic, one phenomenological, and one statistical-all predict that greater diversity increases the temporal stability of the entire community, decreases the temporal stability of individual populations, and increases community productivity. We define temporal stability as the ratio of

Community Dynamics and Stability
2013This chapter explores the implications of climate change for community composition, dynamics, and stability. It also looks at further examples in which climatic variability mediates interactions among species, in some cases degrading community stability and in other cases promoting it.

Spatiality and Community Stability
2020What allows interacting, diverse species to coexist in nature has been a central question in ecology, ever since the theoretical prediction that a complex community should be inherently unstable. Although the role of spatiality in species coexistence has been recognized, its application to more complex systems has been less explored. In this chapter, I
