Summary: Historical geological events and Pleistocene climatic fluctuations have influenced the genetic differentiation and distribution of the buff-bellied hummingbird. The populations were divided into two groups based on their distribution, and past demographic expansion was observed without changes in population size. The potential distribution of the hummingbird expanded during glaciations and habitat differences played a role in recent diversification.

Summary: Shear wave splitting measurements in the Isthmus of Tehuantepec show a predominantly trench-normal pattern of fast polarization orientations, suggesting a corner flow in the mantle wedge and an entrained flow in the subslab region. Fast orientations parallel to the Absolute Plate Motion indicate anisotropy driven by asthenospheric flow in that region. Comparison with measurements in the Mexican subduction zone reveals a 17 degrees clockwise rotation of fast orientations between east and west Mexico, consistent with a 19 degrees clockwise rotation observed in the Middle American Trench.

Summary: After the M8.2 main-shock in the Isthmus of Tehuantepec, Mexico, seismicity in the region has shown clustering along the collision region, and the rate of occurrence of earthquakes has increased. This paper aims to characterize the behavior of seismic activity in the area by analyzing the sequence of magnitudes using the Gutenberg-Richter law, multifractal detrended fluctuation analysis, visibility graph, and nowcasting method. The findings indicate changes in the Tehuantepec ridge dynamics and a time-dependency of the b-value in the Gutenberg-Richter law.

Summary: The study revealed complex genetic structure and historical evolution of Magnolia tree species in the Tropical Montane Cloud Forests of Mexico, influenced by Pleistocene climatic fluctuations. Environmental factors played a crucial role in genetic differentiation, with demographic expansions predating the Last Interglacial period. Conservation management of genetically diverse populations in remnant forest fragments in the three TMCF regions is essential for the protection of these Magnolia populations.

Summary: In this study, a cryptic species complex of the genus Hetaerina was analyzed, revealing the presence of three highly differentiated taxa with considerable genetic isolation. Low climatic niche overlap was also found among the taxa, suggesting specific environmental conditions for each group. It is proposed that H. americana comprises two cryptic species, which may be reproductively isolated by ecological barriers related to niche divergence.

Summary: This study used the EST method to create the first seismic velocity models of the Tehuantepec subduction zone, revealing the geometry of the slab and its surroundings. The findings provide new insights into the geodynamics and tectonics of the region, highlighting the role of geological features in controlling magmatism and plate subduction dynamics.

Summary: A detailed magnetic mineralogy and archaeomagnetic investigation was conducted on red mural painting samples from the Santo Domingo Convent in Oaxaca, Southern Mesoamerica. The study revealed that titanium-poor titanomagnetite is likely responsible for the pictorial remanent magnetization. Despite a low success rate, the methodology described in the study shows potential for dating a wide range of red mural paintings globally.

Summary: This paper argues that there is a bias in studies of wind energy development politics, focusing more on oppositional voices rather than groups that support or have stakes in wind energy projects. Based on fieldwork and interviews, the paper concludes that different responses to wind energy are influenced by ownership claims over land and notions of legitimacy.

Summary: The role of environment and geographic isolation in phenotypic diversity of the Sinaloa Wren in Mexican pacific slope has been studied. The study found significant variation in morphology and plumage reflectance among the subspecies, with environment playing a larger role in morphological variation and a joint effect of geography and environment in plumage reflectance.

Summary: This study focused on the Amazilia rutila hummingbird species in Mexico, and found three genetic groups that were influenced by geographic barriers and environmental differences. The genetic groups showed distinct positions in the environmental space, particularly between individuals/populations from the Pacific slope and the Yucatan Peninsula. The study highlights the importance of preserving evolutionary significant units and considering environmental drivers in conservation actions.

Summary: This study analyzed the vertical stratification traits of seven common tree species and found the existence of vertical niche differentiation. Functional trait differences were observed among different height groups, among co-occurring species within the same height range, and among different parts of the same tree species at different tree heights. Furthermore, contrasting results between lower and higher height ranges in the relationship between functional trait differences and species abundance differences confirmed obvious vertical niche separation in the community.

Summary: This study examines the evolutionary relationships and paleo-distributional patterns of the Squirrel Cuckoo in Mexico using genetic, morphological, and ecological analyses. The findings suggest that the Mexican subspecies P. c. mexicana and P. c. thermophila have divergent evolutionary histories and ecological niches, supporting their classification as separate species-level taxa.

Summary: This study used geometric morphometrics to investigate leaf variation, DNA barcoding and phylogenetic reconstruction to search for genetic gaps, and population genetic methods to compare predicted ecological niches of two species within the Asteropyrum genus. The results revealed overlapping leaf forms, lack of genetic differentiation, and minimal ecological and geographical differences between the two taxa.

Summary: The phylogeographic structure of Attila spadiceus was described using partial Cytb amplicon region analysis, revealing two principal molecular lineages and lack of reflection of morphological variation in the mitochondrial gene tree. The diversification of A. spadiceus is inferred to have started in the Pleistocene, around 1.5 million years ago, driven by the Isthmus of Tehuantepec region forming two molecular lineages.

Summary: The studies reviewed in this article show that roads have the strongest negative effect on connectivity resistance for anurans in temperate regions. Urbanization, fragmentation, and land cover change into agriculture and grasslands also provide resistance to connectivity for anurans worldwide. In both temperate and tropical regions, rivers are the most important natural element negatively affecting connectivity, while streams and forests cover promote connectivity in all regions. This highlights the importance of considering landscape genetics in conservation plans for anuran species.

Summary: Lagomorpha, the order of mammals including pikas, hares, and rabbits, is split into two families: Ochotonidae and Leporidae. By using ultraconserved elements, researchers were able to unravel the phylogeny of lagomorphs and estimate the timing of cladogenesis in their evolution. The study confirmed the split between lagomorphs and rodents about 65 million years ago, with further splits within the lagomorph order occurring around 60 million years ago. The analysis revealed previously unresolved phylogenetic relationships and provided a robust phylogeny for Lagomorpha.

Summary: This study presents the first genomic resource for the Neotropical otter L. longicaudis, providing detailed characterization of its mitochondrial genome. The AT-rich mitochondrial genome of L. longicaudis is 16,436 bp in length and encodes 13 protein coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a putative control region. The study also provides important insights into the genomic features and phylogenetic relationships of L. longicaudis.
