@article{Holland2008StrongEO, title={Strong effect of dispersal network structure on ecological dynamics}, author={Matthew D. Holland and Alan Hastings}, journal={Nature}, year={2008}, volume={456}, pages={792-794} }

A central question in ecology with great importance for management, conservation and biological control is how changing connectivity affects the persistence and dynamics of interacting species. Researchers in many disciplines have used large systems of coupled oscillators to model the behaviour of a diverse array of fluctuating systems in nature. In the well-studied regime of weak coupling, synchronization is favoured by increases in coupling strength and large-scale network structures (for…

Network structure or connectivity pattern is critical in determining collective dynamics among interacting species in ecosystems. Conventional research on species persistence in spatial populations…

Connectivity, Cycles, and Persistence Thresholds in Metapopulation Networks

- Environmental SciencePLoS Comput. Biol.

This work determines the qualitative and quantitative conditions by which dispersal and network structure control the persistence of a set of age-structured patch populations and reveals new insights regarding the determinants of persistence, stability, and thresholds in complex metapopulations.

The effects of dispersal and river spatial structure on asynchrony in consumer–resource metacommunities

- Environmental Science

River network structure influences many important population and community processes. Previous work examining ecological dynamics in river networks has focused on within-trophic-level dynamics, with…

Dispersal-induced synchrony, temporal stability, and clustering in a mean-field coupled Rosenzweig-MacArthur model.

- Environmental ScienceChaos
- 2015

It is shown that asymmetry in dispersal rate plays a crucial role in determining inhomogeneity in an otherwise homogeneous metapopulation and an unusual emergent state in the network, namely, a multi-branch clustered inhomogeneous steady state, which arises due to the intrinsic parameter mismatch among the patches.

A dispersal-induced paradox: synchrony and stability in stochastic metapopulations.

- Environmental ScienceEcology letters
- 2011

It is shown that in many realistic scenarios, dispersal is expected to promote both synchrony and stability at once despite this apparent destabilising influence of synchrony, which is widely held that synchrony paradoxically prevents dispersal-induced stability.

Metacommunity stability and persistence for predation turnoff in selective patches

- Environmental SciencebioRxiv

This study presents how a predation turnoff in selective patches affects the stability and persistence of a metacommunity and identifies the network configurations that exhibit a unique number of clusters.

Effects of branching spatial structure and life history on the asymptotic growth rate of a population

- Environmental ScienceTheoretical Ecology
- 2009

This work applies matrix population models to a stage-structured population in a network of habitat patches connected in a dendritic arrangement to illustrate how spatial structure, directional dispersal, survival, and reproduction interact to determine population growth rate and distribution.

Long-range dispersal promotes species persistence in climate extremes.

- Environmental ScienceChaos
- 2019

This study investigates the persistence of species in a spatial ecological model, where dispersal is considered as a function of temperature and yields how the temperature influences species decision of dispersal, resulting in either short-range or long-range dispersal.

Chimera States in Ecological Network Under Weighted Mean-Field Dispersal of Species

- Environmental ScienceFront. Appl. Math. Stat.
- 2019

This work explores various possible emergent collective population patterns using a simple ecological network model of all-to-all connected patches where a particular type of dispersal process is controlled by a weighted mean-field diffusion to include the failed migration between the interacting patches.

Beyond connectivity: how the structure of dispersal influences metacommunity dynamics

The results illustrate the effectiveness of measures of spatial structure for predicting asynchrony and its effects on community dynamics, providing a deeper understanding of the relationship between spatial structure and species persistence in metacommunities.

Complex dynamics and phase synchronization in spatially extended ecological systems

This work examines the synchronization of complex population oscillations in networks of model communities and in natural systems, where phenomena such as unusual ‘4- and 10-year cycle’ of wildlife are often found.

Dispersal and the Stability of Predator-Prey Interactions

- Environmental ScienceThe American Naturalist
- 1981

Neither spatial structure (texture) nor density-dependent dispersal are additionally required to obtain long-term persistence, and the critical problem of avoiding synchrony in a spatially contiguous, locally unstable system can apparently be solved by size alone.

Persistence of multispecies host-parasitoid interactions in spatially distributed models with local dispersal.

Previous work on spatially distributed host-parasitoid interactions is extended to wider questions of community structure, by considering various three-species systems: two parasitoid species attacking a common host species; two host species attacked by a single parasitoids species; or a host-Parasitoids-hyperparasIToid interaction.

This study identifies a large spatial network of temporary ponds, which are used as breeding sites by several amphibian species, and investigates how the structural properties of the spatial network change as a function of the amphibian dispersal distance and the hydric conditions.

Habitat Patch Arrangement and Metapopulation Persistence of Predators and Prey

The need to combine experimentation with modeling to understand the mechanisms of spatial dynamics is illustrated, as tests whether spatial dynamics can stabilize metapopulations with a small number of patches and tests the influence of patch arrangement.

The metapopulation capacity is introduced, a new measure for highly fragmented landscapes, which is rigorously derived from metAPopulation theory and can easily be applied to real networks of habitat fragments with known areas and connectivities.

Collective dynamics of ‘small-world’ networks

- Computer ScienceNature

Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Graphical Representation and Stability Conditions of Predator-Prey Interactions

- Mathematics, Environmental ScienceThe American Naturalist
- 1963

The general nature of the predator-prey interaction has been depicted as a graph of predator versus prey densities from which conditions for stability of the interaction are predicted, and variations of the graph are introduced, and it is shown that an otherwise unstable interaction may be stabilized by the presence of either an inviolable prey hiding place, or extremely low predation pressure.

Synchronization on small-world networks.

- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2002

Phase synchronization is observed to emerge in the presence of even a tiny fraction P of shortcuts and to display saturated behavior for P > or similar to 0.5, indicating that the same synchronizability as the random network (P=1) can be achieved with relatively small number of shortcuts.
