A complex of white‐eared opossums (Didelphis spp.) is distributed across three distinct areas of South America, but recent taxonomic treatments have disagreed regarding species limits in the group. We used ecological niche modelling to test whether ecological niches have been conserved or have diverged among the three forms in this group. Differences in combinations of niche and range were clear; however, when hypotheses of accessible areas for each species were considered, coarse‐grained niche… 

Which Factors Determine Spatial Segregation in the South American Opossums (Didelphis aurita and D. albiventris)? An Ecological Niche Modelling and Geometric Morphometrics Approach

The morphometric analyses show that a degree of shape discrimination occurs between the species, strengthened by allometric differences, which possibly allowed them to occupy marginally different feeding niches supplemented by behavioral shift in contact areas and a significant, but weak, shift in shape occurs only in D. aurita in sympatric areas.

Patterns of morphological and ecological similarities of small-eared shrews (Soricidae, Cryptotis) in tropical montane cloud forests from Mesoamerica

Estimating species’ potential distributions provides insights to evaluating the effect of geographic barriers on lineage divergence and making stronger inferences when delimiting species, and for detecting divergent ecological niches between candidate species.

Niche models at inter- and intraspecific levels reveal hierarchical niche differentiation in midwife toads

The results support that Alytes toads, examined at both the intra- and interspecific levels, tend to occupy similar, if not identical, climatic environments.

Using Ecological Niche Models and Niche Analyses to Understand Speciation Patterns: The Case of Sister Neotropical Orchid Bees

The results show that the realized niche of Atlantic-Amazonian sister species of orchid bees, which have been previously treated as allopatric populations of three species, had limited niche overlap and similarity, which agrees with their current taxonomy, which treats each of those populations as distinct valid species.

Geographical distribution and niche conservatism in populations of Orthogeomys dariensis (Rodentia: Geomyidae) in the Chocó Biogeographical region

The results support the existence of a single species, O. dariensis (sensu Hafner 2015), with a broad and continuous distribution in the Choco biogeographic region, consistent with recent analyzes of DNA data showing very low genetic divergence between populations north and south of Darien-Baudo.

Comparative niche modeling of two bush-shrikes (Laniarius) and the conservation of mid-elevation Afromontane forests of the Albertine Rift

ABSTRACT Avian endemism in the Albertine Rift is among the highest of any region in Africa. Conservation of these forests is a high priority, but informed prioritization has been hampered by limited

The Importance of Intraspecific Variation for Niche Differentiation and Species Distribution Models: The Ecologically Diverse Frog Pleurodema thaul as Study Case

Whether evolutionary lineages differ in their environmental and geographic niches and how phylogenetic, environmental and geographical distances covary between clades is evaluated and results indicate that there is little overlap between geographic areas and environmental niches.

Molecular systematics of the Amazonian endemic genus Hylexetastes (Aves: Dendrocolaptidae): taxonomic and conservation implications

Phylogenetic analyses support the paraphyly of the polytypic H. perrotii as currently delimited and the elevation of Hylexetastes perrotii uniformis to full species rank, as well as the presence of three evolutionary significant units (ESUs) within this newly delimited species.

Integrating morphology, phylogeography, and ecological niche modeling to explore population differentiation in North African Common Chaffinches

Diagnosing distinct evolutionary taxa requires careful assessment of genetic, morphological, ecological, and behavioral variation within and among populations. In this study, data on phenotype

Divergence is not enough: the use of ecological niche models for the validation of taxon boundaries.

According to the results, niche divergence does not seem to support taxon boundaries at species level, but may have had important consequences for local adaptation and in generating phenotypic diversity at intraspecific level.



Applications of ecological niche modeling for species delimitation: a review and empirical evaluation using day geckos (Phelsuma) from Madagascar.

It is concluded that ecological niche modeling offers great potential for species delimitation, especially for taxonomic groups exhibiting low vagility and localized endemism and for groups with more poorly known distributions, and should be especially sensitive for detecting recent parapatric speciation driven by ecological divergence.

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.

Ecological niche modelling as an exploratory tool for identifying species limits: an example based on Mexican muroid rodents

This work used the genetic algorithm for rule‐set production for modelling the ecological niche as a means of inferring ecological divergence in allopatric populations of muroid rodents for which taxonomic identity is uncertain and shows that niche differentiation is significant in most of the identified phylogroups.

Cryptic Speciation Patterns in Iranian Rock Lizards Uncovered by Integrative Taxonomy

A combination of genetic, morphological and ecological criteria are used to delimit cryptic species within two species complexes, D. chlorogaster and D. defilippii, both distributed in northern Iran.


An approach that combines distribution data, environmental geographic information system layers, environmental niche models, and phylogenetic information to investigate speciation processes is developed and will be increasingly useful as knowledge of distribution and phylogeny of tropical species increases.

Grinnellian and Eltonian niches and geographic distributions of species.

It is argued that it is useful to define Grinnellian and Eltonian niches on the basis of the types of variables used to calculate them, the natural spatial scale at which they can be measured, and the dispersal of the individuals over the environment.

Predicting distributions of known and unknown reptile species in Madagascar

It is concluded that ecological niche modelling using recent locality records and readily available environmental coverage data provides informative biogeographical data for poorly known tropical landscapes, and offers innovative potential for the discovery of unknown distributional areas and unknown species.


It is concluded that the white-eared Didelphis can be split into 3 groups of populations referred to as albiventris, pernigra, and imperfecta, which merit taxonomic recognition at the species level.

Delimiting cohesion species: extreme population structuring and the role of ecological interchangeability

Based on a synthetic evaluation of ecological interchangeability, geographical concordance, and morphological differentiation, it is concluded that Promyrmekiaphila comprises six cohesion species, five of which are cryptic (i.e. undetectable by conventional means).
