Adaptive radiation, nonadaptive radiation, ecological speciation and nonecological speciation
Trends in Ecology & Evolution, 2009Radiations of ecologically and morphologically differentiated sympatric species can exhibit the pattern of a burst of diversification, which might be produced by ecological divergence between populations, together with the acquisition of reproductive isolation ('ecological speciation').

Ecological speciation in a Caribbean marine sponge
Molecular Phylogenetics and Evolution, 2006This is a pre-print from the publisher. No page numbers are provided. ; We are most grateful to M.A. Becerro for assisting in the sample collection. We thank V. Paul, the staV at the Smithsonian Marine Station at Fort Pierce and the Caribbean Coral Reef Ecosystem Program (CCRE) for providing the facilities needed to perform the study.

Ecological Speciation in Corals
2018The ocean is generally a homogenous environment with few geographic barriers that allow populations to connect over hundreds of kilometers, increasing gene flow and slowing down diversification and the formation of species. However, biodiversity in the ocean is vast across thousands of kilometers and even within single individuals (e.g., coral colonies)

The Ecology of Nonecological Speciation and Nonadaptive Radiations
Trends in Ecology & Evolution, 2019Growing evidence for lineage diversification that occurs without strong ecological divergence (i.e., nonadaptive radiation) challenges assumptions about the buildup and maintenance of species in evolutionary radiations, particularly when ecologically similar and thus potentially competing species co-occur.

Ecological Causes of Speciation
1998Abstract How environments cause new species to form remains a fundamental problem in the search for diversity’s origins. Major ideas on the subject were elaborated and discussed earlier this century (Fisher 1930; Wright I 940; Muller 1940; Mayr 1942, 1963; Simpson 1944, 1953; Dobzhansky 1951) but were not resolved.

TAXON, 2010
Abstract Ecology affects each of the three principal processes leading to speciation: genetic differentiation among populations within species, acquisition of reproductive isolation among populations, and the rise of ecological differentiation among such populations, allowing them to coexist.

The ecological basis of speciation
2000Abstract The rise of ecological and phenotypic diversity in adaptive radiation is accompanied by one or more episodes of speciation. Determining how the new species form, and why the pace of species formation is higher during some periods than others, is thus crucial to understanding the process.

Speciation: The Ecological Transition
2000Abstract The role of ecological processes in speciation has been the subject of debate for several decades (Schluter, 1998). Two principal ideas emerge. The most prominent is that divergent natural selection on populations in different envi-ronments drives the development of pre- and postzygote barriers to gene ex change (Mayr, 1942 ...
