Studies of the origin and maintenance of disjunct distributions are of special interest in biogeography. Disjunct distributions can arise following extinction of intermediate populations of a formerly continuous range and later maintained by climatic specialization. We tested hypotheses about how the currently disjunct distribution of the Blossomcrown (Anthocephala floriceps), a hummingbird species endemic to Colombia, arose and how is it maintained. By combining molecular data and models of…

Genetic data and niche differences suggest that disjunct populations of Diglossa brunneiventris are not sister lineages

ABSTRACT Disjunct distributions within a species are of great interest in systematics and biogeography. This separation can function as a barrier to gene flow when the distance among populations

Recent diversification in the high Andes: unveiling the evolutionary history of the Ecuadorian hillstar,Oreotrochilus chimborazo(Apodiformes: Trochilidae)

This work generated a dataset of ten microsatellite markers and complementary data on morphometrics, plumage variation and ecological niches to understand the evolution of Oreotrochilus chimborazo, a high Andean species of hummingbird that might have experienced rapid diversification in the recent past.

Ecological niche modelling of the wattled crane (Bugeranus carunculatus) suggest range expansion and contraction during the Pleistocene

The results support the idea that the current disjunct distribution of the wattled crane is driven by climate oscillations during the Pleistocene that generated range expansion and retraction of the species and also support the hypothesis that theCurrent occurrence of the Species isdriven by other factors such as food and habitat availability.

Complete mitochondrial genomes do not distinguish phenotypically distinct lineages of Andean Coeligena hummingbirds

The results indicate that various evolutionary mechanisms playing out over a complex biogeographic scenario in the Colombian Andes drove divergence in phenotypes and mitochondrial genomes of Coeligena hummingbirds, and lead to alternative hypotheses to be tested with whole-genome analyses.

Realized niche and microhabitat selection of the eastern green lizard (Lacerta viridis) at the core and periphery of its distribution range

Peripheral populations seem to compensate for overall harsher climatic conditions by responding to different parameters of the microhabitat compared to core populations, pointing out the general implications of a higher specialization degree of peripheral populations in relation to climate change and habitat fragmentation.

Modeling Avian Distributions and Niches: Insights into Invasions and Speciation in Birds

This review will introduce the theoretical background of niche concepts and niche conservatism, followed by an outline of popular methods for modeling and analyzing environmental niches.

Henicorhina anachoreta ( Troglodytidae ) , another endemic bird species for the Sierra Nevada de Santa Marta

Evidence that the Henicorhina wood-wren inhabiting the upper slopes of the Sierra Nevada de Santa Marta merits status as a species distinct from the lower élevation taxon, H. bangsi, based on genetic and phenotypic evidence as well as differences in song is presented.

Only if humans leave more room and time to birds and other organisms can be expected to maintain such a number of diverse bird species, although they will keep modifying, splitting, and becoming extinct—but for natural reasons.

Evolución del riesgo de extinción y estado actual de conservación de las aves de Colombia

Periodic assessment of extinction risk is fundamental to monitor progress or regression on species conservation status. We analyzed changes through time in red lists and red data books in Colombia in

Splits , lumps and shuffles

Vocal variation is analysed to assess species limits in two Crypturellus species—groups for which taxonomic changed have been mooted: the red-legged complex of CryptureLLus erythropus and allied forms, and the Brown Tinamou CryptUREllus obsoletus.



Investigating the origin of transoceanic distributions: Mtdna shows Mabuya lizards (Reptilia, Scincidae) crossed the Atlantic twice

Two alternative hypotheses explaining the presence of Mabuya in both Africa and tropical America are refuted on the basis of molecular clock considerations.

Selection and geographic isolation influence hummingbird speciation: genetic, acoustic and morphological divergence in the wedge-tailed sabrewing (Campylopterus curvipennis)

Coalescent analyses of the evolution of phenotypic traits suggest that selection is driving song evolution in wedge-tailed sabrewing lineages in Mesoamerica but drift could not be rejected as a possibility for morphological divergence.


It is shown that phylogeographic studies in vertebrates suggest that divergence of alleles in ancestral species can comprise from less than 10% to over 50% of the total divergence between sister species, suggesting that the problem of ancestral polymorphism in dating population divergence can be substantial.

Niche Conservatism and Disjunct Populations: A Case Study with Painted Buntings (Passerina ciris)

All present-day niche models for both species predicted a single contiguous breeding range, which suggests that the gap in the Painted Bunting range is not bioclimatic in origin, and comparative analyses of the three different environments suggest little biOClimatic divergence.

Climatic niche divergence or conservatism? Environmental niches and range limits in ecologically similar damselflies.

N niche differences across Fennoscandia suggest that species differences in physiological tolerances limit range expansions northward, and that current and future climate could have large effects on the distributional ranges of these and ecologically similar insects.

A single Mid-Pleistocene long-distance dispersal by a bird can explain the extreme bipolar disjunction in crowberries (Empetrum)

It is concluded that a single dispersal by a bird from northwestern North America to southernmost South America, taking place in the Mid-Pleistocene, is sufficient to explain the disjunction in crowberries.

Limits to elevational distributions in two species of emberizine finches: disentangling the role of interspecific competition, autoecology, and geographic variation in the environment

Focusing on Buarremon brush-finches, a group in which distributions represent one of the best examples of the potential role of competition limiting elevational ranges, it is shown that when distributions are compared along axes of climatic variation, some patterns of elevational range variation do appear to be consistent with predictions of the hypothesis that release from competition underlies expanded Elevational ranges in allopatry.

Molecules, ecology, morphology, and songs in concert: how many species is Arremon torquatus (Aves: Emberizidae)?

This study begins to tackle the thorny issue of species delimitation in a complicated group of Neotropical passerine birds in which sets of characters vary substantially across space, but do not obviously vary in a concerted fashion.


The results do not support an ecological speciation model for Mexican Jay lineages because, in most cases, the allopatric environments they occupy are not significantly more divergent than expected under a null model.
