Introduction
Marco Suarez-Atilano currently works as Lecturer in Faculty of Sciences, UNAM. Mexico. Marco does research in Phylogeography, Species delimitation and Integrative Taxonomy. Their most recent publication is 'Genomic and environmental insights and conservation challenges for two hybridizing iconic crocodile species across Mexico: Crocodylus acutus and C. moreletii'.

Hybridization is of key relevance for conservation of wild species, and yet it is still one of the most controversial issues in conservation. Identifying historical and contemporary factors promoting the formation and maintenance of hybrids is crucial for the management of endangered species, as well as characterizing the environmental factors and...
The phylogenetic relationships among black-tailed rattlesnakes remain poorly understood and some authors indicated that the diversity of this group has been underestimated and additional analyses are required to clarify the biogeographic patterns throughout its distribution in Mexico. Therefore, the aim of this study was to elucidate the phylogenet...
Context:
Gene flow in riparian ecosystems is influenced by landscape features such as orography, climate, and salinity. The 'downstream increase in genetic diversity' (DIGD) hypothesis states that the unidirectionality of the watercourse causes an accumulation of genetic diversity towards downstream populations, while upstream populations are more...
Habitat loss and fragmentation are among the greatest threats to biodiversity since unsuitable habitat can be a significant barrier to gene flow, disrupting the connectivity of populations. In this scenario, landscape genetic approaches have been applied as invaluable tools to demonstrate how contemporary habitat alterations affect gene flow. In th...
Roberts' False Brook Salamander (Pseudoeurycea robertsi) is a critically endangered plethodontid salamander, endemic to the Ne-vado de Toluca Volcano (NTV), Mexico. Little is known about the biology and ecology of this species, including its microhabitats. Thus, this study aimed to collect basic information about P. robertsi. We sampled fourteen fo...
Invasive species represent a major threat for biodiversity. The numbers of independent introductions, introduced propagules, and introduction episodes are critical aspects for invasion success. Here, we traced the source(s) of introduction and determined the historical route of invasion in order to understand the main stages of the invasion process...
Aim:
To infer the geological and climatic factors that have shaped the genetic diversity and structure of a willow species (Salix humboldtiana) in three basins of Central Mexico.
Location:
Central Mexico.
Methods:
We collected samples from 11 populations across two hydrological basins (Balsas and Lerma) and one population from another basin (A...
Land use changes are threatening the maintenance of biodiversity. Genetic diversity is one of the main indicators of biological diversity and is highly important as it shapes the capability of populations to respond to environmental changes. We studied eleven populations of Pseudoeurycea robertsi, a micro-endemic and critically endangered species f...
Interspecific hybridization can lead to adaptation and speciation, especially in the context of recent radiations. The emblematic Crocodylus (true crocodiles) is the most broadly distributed, ecologically diverse, and species-rich crocodylian genus. Nonetheless, their within-species evolutionary processes are poorly resolved mainly due to their pot...
Principles of Maximum-Likelihood for phylogenetic inference (in Spanish)
The runner bean is a legume species from Mesoamerica closely related to common bean (Phaseolus vulgaris). It is a perennial species, but it is usually cultivated in small-scale agriculture as an annual crop for its dry seeds and edible immature pods. Unlike the common bean, P. coccineus has received little attention from a genetic standpoint. In th...
Aim
A fundamental problem in evolutionary biology has been understanding the role of environmental factors in the process of genetic diversification. Our main goal was to define the ecological niches of two Boa imperator lineages, in order to assess if environmental drivers could be associated with the divergence and genetic variation between them....
AimTo evaluate the genetic diversity and phylogeographical structure of Boa constrictor imperator, in order to identify the key historical events responsible for its current distribution and diversity.LocationThe Neotropical region of Mexico and mainland Central America.Methods
We used data from the mitochondrial cytochrome b gene, nuclear ornithin...
Only one study has described the population genetic structure of Boa constrictor imperator and only in a single naturally colonized island. B.c. imperator, a snake with a naturally wide distribution across the Neotropics, was introduced to Cozumel Island, Mexico, in 1971. At present, it is one of the most abundant, widely distributed, terrestrial v...

Hello everyone:
I'm looking for any method which allows to represent (or measure) spatially the genetic diversity in a given landscape (interpolation maybe). I ran EEMS (Petkova 2017) which infers patterns of gene flow among localities and I tried to ran AIS (Miller 2005) and despite this last one works well with microsats (13 loci) the program just crashed with DNA sequences (1500 bp) and SNP's (6000 biallelic), it seems this method was put aside and support for this is not longer available. Thanks in advance
Hello everyone!
I’m trying to perform a model checking over my 4 computed demographic scenarios (SNP data), I already ran the 4 million of scenarios recommended for my data set and this is the first time a I’ve got this warning when I try to perform a model checking:
Something happened during the analysis posterior_prob_4M_scn4 : Program of thread 'posterior_prob_4M_scn4' exited (with return code 1) unsuccessfully.
scenario[rt.scenteste-1].nparam = 10
apres detphistarOK nphistarOK=16
nphistarOK=16 nstat=50
Not enough suitable particles (16)to perform model checking. Stopping computations.
Did anyone have deal with this warning? I’m including the image of my pre evaluation of priors. Thanks in advance
