The dynamical theory of coevolution: a derivation from stochastic ecological processes
It is shown that the coevolutionary dynamic can be envisaged as a directed random walk in the community's trait space and a quantitative description of this stochastic process in terms of a master equation is derived. Expand
On the origin of species by sympatric speciation
This work uses multilocus genetics to describe sexual reproduction in an individual-based model and considers the evolution of assortative mating, which leads to reproductive isolation between ecologically diverging subpopulations and conforms well with mounting empirical evidence for the sympatric origin of many species. Expand
Hybridization and speciation
A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation. Expand
Evolutionary Branching and Sympatric Speciation Caused by Different Types of Ecological Interactions
It is shown that evolution under branching conditions selects for assortativeness and thus allows sexual populations to escape from fitness minima and concludes that evolutionary branching offers a general basis for understanding adaptive speciation and radiation under a wide range of different ecological conditions.

Maturation trends indicative of rapid evolution preceded the collapse of northern cod
It is shown that, up until the moratorium, the life history of northern cod continually shifted towards maturation at earlier ages and smaller sizes, which strongly suggests fisheries-induced evolution of maturation patterns in the direction predicted by theory. Expand
Speciation along environmental gradients
It is shown that along an environmental gradient, evolutionary branching can occur much more easily than in non-spatial models, and this facilitation is most pronounced for gradients of intermediate slope. Expand
The Geometry of Ecological Interactions: Simplifying Spatial Complexity
This volume, written by world experts in the field, gives detailed coverage of the main areas of development in spatial ecological theory, integrating a perspective from field ecology with novel methods for simplifying spatial complexity and offers a didactical treatment with a gradual increase in mathematical sophistication.

Live Where You Thrive: Joint Evolution of Habitat Choice and Local Adaptation Facilitates Specialization and Promotes Diversity
Unless trapped by maladaptive genetic constraints, joint evolution of local adaptation and habitat choice in the models analyzed here always leads to specialists, independent of life cycle, density regulation, and trade‐off strength, thus raising the bar for evolutionarily sound explanations of generalism. Expand
Evolutionary dynamics of predator-prey systems: an ecological perspective
A formal framework for this purpose is suggested, extending from the microscopic interactions between individuals through the mesoscopic population dynamics responsible for driving the replacement of one mutant phenotype by another, to the macroscopic process of phenotypic evolution arising from many such substitutions. Expand
Adaptive Dynamics of Pathogen–Host Interactions
This chapter explains why the traditional approach of predicting evolutionary outcomes by maximizing the basic reproduction ratio of a disease is not always appropriate. Since pathogens tend toExpand
