Detecting multivariate interactions in spatial point patterns with Gibbs models and variable selection by Rajala, T., Murrell, D. J., Olhede, S. C.

“…We propose a method for detecting significant interactions in very large multivariate spatial point patterns. This methodology thus develops high dimensional…”

The evolution of density–dependent dispersal by Travis, Justin M. J., Murrell, David J., Dytham, Calvin

“…Despite a large body of empirical evidence suggesting that the dispersal rates of many species depend on population density, most metapopulation models assume…”

Beetles in Fragmented Woodlands: A Formal Framework for Dynamics of Movement in Ecological Landscapes by Murrell, David J., Law, Richard

“…1. We consider the movement of carabid beetles in a fragmented woodland landscape. Landscape ecology has lacked a formal framework for the analysis of dynamics…”

THE COMMUNITY-LEVEL CONSEQUENCES OF SEED DISPERSAL PATTERNS by Levine, Jonathan M, Murrell, David J

“…Because it lays the template from which communities develop, the pattern of dispersed seed is commonly believed to influence community structure. To test the…”

Heteromyopia and the spatial coexistence of similar competitors by Murrell, David J., Law, Richard

“…Most spatial models of competing species assume symmetries in the spatial scales of dispersal and interactions. This makes analysis tractable, and has led to…”

Population Growth in Space and Time: Spatial Logistic Equations by Law, Richard, Murrell, David J., Dieckmann, Ulf

“…How great an effect does self-generated spatial structure have on logistic population growth? Results are described from an individual-based model (IBM) with…”

On moment closures for population dynamics in continuous space by Murrell, David J., Dieckmann, Ulf, Law, Richard

“…A first-order moment closure, the mean-field assumption that organisms encounter one another in proportion to their spatial average densities, lies at the…”

The evolution of dispersal distance in spatially-structured populations by Murrell, David J., Travis, Justin M. J., Dytham, Calvin

“…Most evolutionary models of dispersal have concentrated on dispersal rate, with emigration being either global or restricted to nearest neighbours. Yet most…”

A Simple Explanation for Universal Scaling Relations in Food Webs by F. J. Frank van Veen, Murrell, David J.

“…Much of the interest in food webs has been driven by a search for universal patterns that could indicate common organizing principles. In an approach that…”

When does local spatial structure hinder competitive coexistence and reverse competitive hierarchies? by Murrell, David J.

“…Classical theory states that if conspecifics have a greater competitive effect on individuals than heterospecifics then coexistence should occur, and…”

Terrestrial-focused protected areas are effective for conservation of freshwater fish diversity in Lake Tanganyika by Britton, A.W., Day, J.J., Doble, C.J., Ngatunga, B.P., Kemp, K.M., Carbone, C., Murrell, D.J.

“…Freshwater protected areas are rarely designed specifically for this purpose and consequently their conservation benefit cannot be guaranteed. Using Lake…”

The memory of spatial patterns: changes in local abundance and aggregation in a tropical forest by Flügge, Anton J, Olhede, Sofia C, Murrell, David J

“…The current spatial pattern of a population is the result of previous individual birth, death, and dispersal events. We present a simple model followed by a…”

When do we have the power to detect biological interactions in spatial point patterns? by Rajala, T, Olhede, S, Murrell, D. J

“…Determining the relative importance of environmental factors, biotic interactions and stochasticity in assembling and maintaining species-rich communities…”

Local Spatial Structure and Predator‐Prey Dynamics: Counterintuitive Effects of Prey Enrichment by Murrell, David J.

“…The Lotka‐Volterra predator‐prey model with prey density dependence shows the final prey density to be independent of its vital rates. This result assumes the…”

Uniting pattern and process in plant ecology by Murrell, David J., Purves, Drew W., Law, Richard

“…A current focus of ecology is the investigation of the effect of the spatial dimension on population and community dynamics. However, most of the large body of…”
