Neutral models in ecology assume that all species are demographically equivalent, such that their abundances differ ultimately because of demographic stochasticity rather than selection. In spite of their simplicity, neutral models have been found to accurately reproduce static patterns of biodiversity for diverse communities. However, the same neutral

Among numerous mechanisms shaping the unimodal relationship between diversity and community biomass, the trade-off model of "CRS" theory is the most famous one. However, recent researches indicate that this relationship may also emerge under the neutral model where all species are identical with each other.

Carbon Neutral Communities: Model for Integrating Climate Action into Development Planning
2021Climate change has become the axis of discussions pertaining to economic development across the globe. The world is at a tipping point where we cannot afford business-as-usual models that are highly dependent on fossil fuels. Low-emission development strategies have put carbon as an indicator of development.

Topology matters: Network topology affects outcomes from community ecology neutral models [PDF]
Computers, Environment and Urban Systems, 2008 Abstract Topology affects outcomes of processes in planar networks. Hexagon tessellations have different performance than, and are often superior to, square tessellations in applications such as fluid dynamics, percolation theory, self-avoiding walks, survey sample design, and quantization.

Species abundance distribution and population dynamics in a two-community model of neutral ecology
Physical Review E, 2006Explicit formulas for the steady-state distribution of species in two interconnected communities of arbitrary sizes are derived in the framework of Hubbell's neutral model of biodiversity. Migrations of seeds from both communities as well as mutations in both of them are taken into account.

Evolution; International Journal of Organic Evolution, 2017 Community characteristics reflect past ecological and evolutionary dynamics. Here, we investigate whether it is possible to obtain realistically shaped modeled communities-that is with phylogenetic trees and species abundance distributions shaped similarly to typical empirical bird and mammal communities-from neutral community models.

INVASIBILITY AND SPECIES RICHNESS OF A COMMUNITY: A NEUTRAL MODEL AND A SURVEY OF PUBLISHED DATA
Ecology, 2004A widespread but controversial idea in ecology states that the number of invaders of a species assemblage depends on its species richness. Both negative and positive relationships have been reported. We examined whether a simple neutral model where assemblages are generated by drawing individuals from two pools of identical species (native and alien ...

Effects of stream topology on ecological community results from neutral models
Ecological Modelling, 2012Abstract While neutral theory and models have stimulated considerable literature, less well investigated is the effect of topology on neutral metacommunity model simulations. We implemented a neutral metacommunity model using two different stream network topologies, a widely branched network (wide tree) and a narrowly branched network (high tree ...

Convergence of Community Structure: Neutral Model vs. Field Data
Ecology, 1980When I started my study I did not know that species densities were so similar along the two transects. Within the general Chilean area of study there are at least 1 1 species of lizards (Donoso-Barros 1966), out of which nine were found in the transect. In the Californian sites there are eight species.

Spatially explicit models relating to plant populations have developed little since Felsenstein (1975) pointed out that if limited seed dispersal causes clustering of individuals, such models cannot reach an equilibrium. This paper aims to resolve this issue by modifying the Neyman-Scott cluster point process. The new point processes are dynamic models
