The genetic basis of evolution, adaptation and speciation
Molecular Ecology, 2011A primary question in biology concerns the genetic basis of the evolution of novel traits, often in response to environmental changes, and how this can subsequently cause species isolation. This topic was the focus of the symposium on the Genetics of Speciation and Evolution at the annual meeting of the Canadian Society for Ecology and Evolution, held ...

Adaptation, Speciation and Time
Zoologica Scripta, 1976AbstractFryer, G. (Windermere Laboratory, Ambleside, Westmorland LA22 OLP, U.K.) Adaptation, speciation and time. Zool. Scr. 5 (3–4): 171–172, 1976.—While evolution is usually a gradual process, large morphological changes cannot be excluded as possible agents as is shown by specific examples. Speciation and adaptation are usually synchronous processes

Speciation in evolutionary algorithms
Proceedings of the 13th annual conference on Genetic and evolutionary computation, 2011The use of niching methods for solving real world optimization problems is limited by the difficulty to obtain a proper setting of the speciation parameters without any a priori information about the fitness landscape. To avoid such a difficulty, we propose a novel method, called Adaptive Species Discovery, that removes the basic assumption of perfect ...

Models of adaptation and speciation
2007Chapter 1 There are two ways in which a population can adapt to a rapid environmental change or habitat expansion. It may either adapt through new beneficial mutations that subsequently sweep through the population or by using alleles from the standing genetic variation.

Speciation and Adaptation in Birds
Abstract The field of avian speciation has matured into a rich, diverse, and global endeavor. This chapter focuses on four specific areas of the extensive speciation literature, with an emphasis on studies applying molecular approaches: (1) pre- and postmating reproductive isolating barriers in birds, (2) the genomics of avian ...David P.

Evolution and speciation on holey adaptive landscapes
Trends in Ecology & Evolution, 1997Sewall Wright's powerful metaphor of rugged adaptive landscapes has formed the basis for discussing evolution and speciation for more than 60 years. However, this metaphor, with its emphasis on adaptive peaks and valleys, is to a large degree a reflection of our three-dimensional experience.

Ecological Genomics of Adaptation and Speciation in Fungi
2013Fungi play a central role in both ecosystems and human societies. This is in part because they have adopted a large diversity of life history traits to conquer a wide variety of ecological niches. Here, I review recent fungal genomics studies that explored the molecular origins and the adaptive significance of this diversity.

Adaptive Speciation in Agricultural Pests
2004Introduction Agricultural crops provide an ideal environment for adaptive speciation of pest species. They represent recently colonized habitats, harbor small incipient pest populations, and form environments in which not all the resources are already occupied [together referred to as ecological opportunity, see Schluter (2000)].
