“…We examined six hummingbird species that according to phylogenetic taxonomies belong to different major clades: T. ruckeri in the Hermits (Phaethornithinae), C. thalassinus in the Mangoes (Polytmini), S. sephanoides in the Coquettes (Lophornithini), C. costae in the Bees (Mellisugini), A. chianogaster and H. leucotis in the Emeralds (Trochilini). The clades here were listed starting with the one having the oldest split and following the order in which the splitting continued (Hernández-Baños et al, 2014;McGuire et al, 2009). We compared the estimated fundamental niches (ellipses) of these six species with respect to the phylogenetic relationships among them and noted that T. ruckeri, which has the oldest split in the phylogeny, had the most different estimated fundamental niche (red ellipse in Fig.…”

In the last years, studies that question important conceptual and methodological aspects in the field of ecological niche modeling (and species distribution modeling) have cast doubts on the validity of the existing methodologies. Particularly, it has been broadly discussed whether it is possible to estimate the fundamental niche of a species using presence data. Although it has being identified that the main limitation is that presence data come from the realized niche, which is a subset of the fundamental niche, most of the existing methods lack the ability to overcome it, and then, they fit objects that are more similar to the realized niche. To overcome this limitation, we propose to use the region that is accessible to the species (based on its dispersal abilities) to determine a sampling distribution in environmental space that allow us to quantify the likelihood of observing a particular environmental combination in a sample of presence points. We incorporate this sampling distribution into a multivariate normal model (Mahalanobis model) by creating a weight function that modifies the probabilities of observing an environmental combination in a sample of presences as a way to account for the uneven availability of environmental conditions. We show that the parameters of the modified, weighted-normal model can be approximated by a maximum likelihood estimation approach, and used to draw ellipsoids (confidence regions) that represent the shape of the fundamental niche of the species. We illustrate the application of our model with two worked examples: (i) using presence points of an invasive species and an accessible area that includes only its native range, to evaluate whether the fitted model predicts confirmed establishments of the species outside its native range, and (ii) using presence data of closely related species with known accessible areas to exhibit how the different dispersal abilities of the species constraint a classic Mahalanobis model. Taking into account the distribution of environmental conditions that are accessible to the species indeed affected the estimation of the ellipsoids used to model their fundamental niches.

Genetic structure and phylogeographic patterns of natural populations are of great importance in assessing the conservation status of species. These population properties can be estimated using molecular markers of either mitochondrial DNA (mtDNA) or nuclear DNA (nDNA) to understand the historical, ecological and dispersal patterns that influence genetic exchange within and between populations. Basilinna xantusii is a sexually dimorphic hummingbird endemic to the Baja California Peninsula (BCP). It comprises three ancestral mitochondrial lineages linked to vicariant events, late Pleistocene climate changes and the geographical distribution of oases. This study aimed to determine and understand the current population genetic structure of this hummingbird. The genotypes of 16 microsatellite loci from 100 individuals collected across the geographical range of this species were compared with mtDNA sequences previously published. Cluster analyses identified five populations, two with almost no genetic admixture in the northern part of the BCP and three others with varying levels of admixed ancestry across the BCP. In San José de Magdalena, at the northernmost end of the range of Xantus's Hummingbird, 40% of individuals collected belong to one genetic cluster and the remaining 60% to another, both genetic clusters showing very little admixed ancestry. We hypothesize that, despite being in sympatry, these individuals do not interbreed, unlike the other populations where individuals showed ancestry coefficients of the other genetic groups. The philopatric behaviour of males and the long‐range dispersal capacity of females probably determine the observed genetic differentiation pattern. The mito‐nuclear discordance detected could be due to the molecular markers used and to female‐biased dispersal. Gene flow is asymmetric in this species, being greater from north to south than vice versa, which is probably related to differences in the seasonality of precipitation across the BCP and to urbanization of the oases.
