The island syndrome is a suite of adaptive changes characterized by alterations in ecology, behavior, life history traits, morphology, and physiological processes derived from convergent evolution. Certain island-dwelling birds, such as the Blue Mockingbird (Melanotis caerulescens), have evolved distinct morphological traits, including longer, deep...
The environment and host behaviour are pivotal factors influencing the diversity and composition of microbes in birds’ plumage. The Violet-crowned Hummingbird (Ramosomyia violiceps) is an important pollinator in Western Mexico and is widely distributed across various environments. Differences in bacterial abundance, richness, and composition in the...
The gut microbiome of wild birds contributes to host fitness by supporting nutrient absorption, toxin processing, and immune function. It also fights bacterial pathogens through competitive exclusion and the production of antimicrobial metabolites. This study analyzed the in vitro antagonistic activity of bacteria isolated from the feces of the vio...
E n México, existen alrededor de 140 especies de murciélagos, de las cuales, únicamente tres ingieren sangre de mamíferos y aves. El resto presentan diversas formas de alimentarse, algunos ingieren frutos (frugívoros), otros comen artrópodos o carne (artropodófagos y carnívoros), otros más prefieren el néctar de las flores (nectarívoros). Esta gran...
Historical geological events and Pleistocene climatic fluctuations have played important roles in shaping distribution and population differentiation across taxa. The buff-bellied hummingbird (Amazilia yucatanensis) is widely distributed along the Gulf of Mexico slope and the Yucatan Peninsula. Here, we obtained measurements and sequenced two mitoc...
A major barrier to advancing ornithology is the systemic exclusion of professionals from the Global South. A recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed a long-standing pattern of highlighting individuals, knowledge, and views from the Global North, while largely omitting...
Mexico has over 23,300 vascular plant species, half of which are endemic, and ranks third in species richness in the Americas. Compiling checklists and floras, and examining phylogenetic relationships are the ways we develop a better understanding of species richness. The plant checklist and the metadata of the sequences in GenBank can help determi...
The formation of the Trans-Mexican Volcanic Belt (TMVB) and Pleistocene climatic fluctuations have been shown to influence the diversification of lineages and species distributed throughout central Mexico. In some taxa, however, evidence of lineage diversification is not easily recognized, as often is the case in reptiles. Here we present a phyloge...

Background
The advance of the COVID-19 pandemic and spread of SARS-CoV-2 around the world has generated the emergence of new genomic variants. Those variants with possible clinical and therapeutic implications have been classified as variants of concern (VOCs) and variants of interest (VOIs).Objective
This study aims to describe the COVID-19 pandem...
Lagomorpha (lagomorphs), the order of mammals including pikas, hares, and rabbits, is distributed on all continents. The order currently is hypothesized to comprise 12 genera and 108 species, split into two families: Ochotonidae (pikas) and Leporidae (rabbits and hares). Molecular and morphological attempts have been undertaken to resolve the phylo...
Genomics is the discipline that studies the structure, function, and evolution of genomes and addresses the methodological processes used tosequence and assemble the genome. Analyzing sequencing data requires state-of-the-art computational resources and specialized mathematicalalgorithms and software, which are together known as bioinformatics. The...

EL COLIBRÍ CORONA VIOLETA (Leucolia violiceps) mantiene una amplia distribución en el occidente de México, en estado de Jalisco lo podemos encontrar muy abundante en los parques y jardines de las ciudades, bosques tropicales, selvas secas, vegetación ribereña y en campos agrícolas del estado. Su plumaje es iridiscente en la parte dorsal de tonos br...
The Tropical Montane Cloud Forest (TMCF) is a highly dynamic ecosystem that has undergone frequent spatial changes in response to the interglacial-glacial cycles of the Pleistocene. These climatic fluctuations between cold and warm cycles have led to species range shifts and contractions-expansions, resulting in complex patterns of genetic structur...
Global climate change is associated with changes in precipitation patterns and an increase in extreme weather events, which might shift the geographic distribution of species. Despite the importance of this topic, information is lacking for many species, particularly tropical birds. Here, we developed species distribution models (SDMs) to evaluate...
Two sibling bare-backed bat species (Pteronotus fulvus and P. gymnonotus) have been traditionally differentiated by their size. However, intermediate specimens between the two species have been found in sympatric populations along southern Mexico and it has been suggested that they may be the outcome of a hybridization process between the two speci...
Recent historical and anthropogenic changes in the landscape causing habitat fragmentation can disrupt the connectivity of wild populations and pose a threat to the genetic diversity of multiple species. This study investigated the effect of habitat fragmentation on the structure and genetic diversity of the Mexican greater funnel-eared bat (Natalu...
In December 2019, the first cases of the novel severe acute respiratory syndrome corona-virus 2 (SARS-CoV-2) were identified in the city of Wuhan, China. Since then, it has spread worldwide with new mutations being reported. The aim of the present study was to monitor the changes in genetic diversity and track non-synonymous substitutions (dN) that...
In December 2019, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in the province of Wuhan, China. Since then, it has spread worldwide with new mutations being reported. We performed genomic analysis to identify the changes in genetic diversity of SARS-CoV-2 between December 2019 and November 2020, and through molecul...
The Pleistocene climate cycles and mountain uplift both affected the diversification of taxa in Mesoamerica. Yet, phylogeographic breaks and demographic responses of co-distributed taxa are not congruent. Investigation of more species with widespread distributions across Mexico and Central America will help shed light on how Earth historical events...
Los fructanos son carbohidratos de estructura química diversa distribuidos en diferentes taxa. En las plantas, además de constituir una importante fuente de carbono, han sido asociados con la tolerancia a diferentes tipos de estrés. La biosíntesis de estos compuestos se lleva a cabo por la acción de las enzimas fructosiltransferasas, mientras que s...
Pleistocene climate cycles have been recognized to be a major driver of postglacial northward range expansion of North American bird populations. During glacial maxima, allopatric lineages that were reproductively isolated might have come into secondary contact with one another during expansion periods and the genetic signatures of past hybridizati...
Mexico is a center of diversification for the genus Quercus, with an important number of taxa occurring along the Trans-Mexican Volcanic Belt (TMVB). However, the impact of the interaction between historical and current climatic variation and geological heterogeneity in the TMVB on the genetic and phenotypic diversification within oak species has b...
Large-scale phylogeographical patterns and the underlying factors driving species divergence in Mesoamerica are poorly understood, but it is widely documented that tectonic events and Pleistocene climate changes play an important role in determining species diversification. As glaciations in Mesoamerica developed only around high mountains, one hyp...

Phylogeographical work on cloud forest-adapted species provides inconsistent evidence on cloud forest dynamics during glacial cycles. A study of Rhipsalis baccifera (Cactaceae), a bird-dispersed epiphytic mistletoe cactus, was conducted to investigate genetic variation at sequence data from nuclear [internal transcribed spacer (ITS), 677 bp] and ch...
The cloud forests of Mesoamerica are highly endangered habitats and the existence of narrowly distributed cryptic endemics will increase the number of taxa at potential risk of extinction. Here, we investigate genetic divergence between populations of the azure-crowned hummingbird (Amazilia cyanocephala), a species complex of endemic hummingbirds t...
AimWe used mitochondrial DNA sequences to reconstruct the phylogenetic relationships of Mesoamerican Amazilia hummingbirds (Trochilidae). The phylogeny was used to identify vicariance scenarios, reconstruct ancestral biogeographical areas, and investigate the role of geological events in generating genetic divergence through vicariance events. Loca...
