Abstract We developed an approach that combines distribution data, environmental geographic information system layers, environmental niche models, and phylogenetic information to investigate speciation processes. We used Ecuadorian frogs of the family Dendrobatidae to illustrate our methodology. For dendrobatids there are several cases for which there is significant environmental divergence for allopatric and parapatric lineages. The consistent pattern that many related taxa or nodes exist in… 

DOES NICHE CONSERVATISM PROMOTE SPECIATION? A CASE STUDY IN NORTH AMERICAN SALAMANDERS

The results demonstrate that even the relatively subtle climatic differences between montane and lowland habitats in eastern North America may play a key role in the origin of new species.

Genomic data reject the hypothesis of sympatric ecological speciation in a clade of Desmognathus salamanders

The hypothesis of ecological speciation based on microhabitat partitioning is rejected and it is suggested that there are two cryptic lineages, each containing the same pair of morphotypes.

Evidence for ecological processes driving speciation among endemic lizards of Madagascar

The findings provide strong evidence of a role for ecological processes driving speciation, rather than the classic expectation of speciation through geographic isolation, but demonstrate that the link between ecological speciation and parapatry is complex and requires further analysis of a broader taxonomic sample to fully resolve.

Niche Divergence at Intraspecific Level in the Hyrcanian Wood Frog, Rana pseudodalmatina: A Phylogenetic, Climatic, and Environmental Survey

The findings strongly support the hypothesis that WRC and ERC have undergone substantial niche divergence and are constrained by a unique set of climatic and macro-environmental conditions.

Understanding the ecological niche to elucidate spatial strategies of the southernmost Tupinambis lizards

This work modelled species distributions of two phylogenetically, geographically and ecologically close Tupinambis species (Teiidae) that occupy the southernmost area of the genus distribution in South America and proposed that niche plasticity could be the mechanism enabling their co-occurrence.

Adding more ecology into species delimitation: ecological niche models and phylogeography help define cryptic species in the black salamander (Aneides flavipunctatus).

This work demonstrates the ease and utility of using spatial analyses of environmental data and phylogenetics in species delimitation, especially for groups displaying fine-scaled endemism and cryptic species.

Phylogenetic patterns in zopherine beetles are related to ecological niche width and dispersal limitation

Niche conservatism has been proposed as the mechanism driving speciation in temperate montane clades through range fragmentation during climatic oscillations. Thus, a negative relationship between

Ecological and geographic modes of species divergence in wild tomatoes.

This work used climatic, geographic, and biological data from nine wild Andean tomato species to describe each species' ecological niche and to evaluate the likely ecological and geographical modes of speciation in this clade.

Divergent lineages and conserved niches: using ecological niche modeling to examine the evolutionary patterns of the Nile monitor (Varanus niloticus)

Examining the climatic niche of three genetic lineages of the Nile monitor (Varanus niloticus) to better understand the processes involved in generating patterns of genetic variation, and to potentially clarify their taxonomic status, indicates an allopatric mode of differentiation.

Environmental niche divergence between genetically distant lineages of an endangered water beetle

Using a modelling approach directed to generate niche representation from distributional data, a significant environmental niche divergence for allopatric lineages of O. glaber was found that followed an aridity gradient.
