Abstract
Multiple geological and climatic events have created geographical or ecological barriers associated with speciation events, playing a role in biological diversification in North and Central America. Here, we evaluate the influence of the Neogene and Quaternary geological events, as well as the climatic changes in the diversification of the colubrid snake genus Rhadinaea using molecular dating and ancestral area reconstruction. A multilocus sequence dataset was generated for 37 individuals of Rhadinaea from most of the biogeographical provinces where the genus is distributed, representing 19 of the 21 currently recognized species, and two undescribed species. Our analyses show that the majority of the Rhadinaea species nest in two main clades, herein identified as "Eastern" and "Southern". These clades probably diverged from each other in the early Miocene, and their divergence was followed by 11 divergences during the middle to late Miocene, three divergences during the Pliocene, and six divergences in the Pleistocene. The ancestral distribution of Rhadinaea was reconstructed across the Sierra Madre del Sur. Our phylogenetic analyses do not support the monophyly of Rhadinaea. The Miocene and Pliocene geomorphology, perhaps in conjunction with climate change, appears to have triggered the diversification of the genus, while the climatic changes during the Miocene probably induced the diversification of Rhadinaea in the Sierra Madre del Sur. Our analysis suggests that the uplifting of the Trans-Mexican Volcanic Belt and Chiapan-Guatemalan highlands in this same period resulted in northward and southward colonization events. This was followed by more recent, independent colonization events in the Pliocene and Pleistocene involving the Balsas Basin, Chihuahuan Desert, Pacific Coast, Sierra Madre Occidental, Sierra Madre Oriental, Sierra Madre del Sur, Trans-Mexican Volcanic Belt, and Veracruz provinces, probably driven by the climatic fluctuations of the time.

Abstract
Background Mesoamerica is a remarkable region with a high geological and ecological complexity. Within northern Mesoamerica, the biotic province of the Sierra Madre del Sur (SMS) in southwestern Mexico harbors exceptionally high avian endemism and diversity. Herein, we searched for spatially and temporally concordant phylogeographic patterns, in four bird genera from three distinct avian orders co-distributed across Mesoamerica and investigated their causes through hypothesis testing regarding historical processes. Selected species include endemic and differentiated populations across the montane forests of Mesoamerica, and particularly within the SMS. Results We gathered mitochondrial DNA sequences for at least one locus from 177 individuals across all species. We assessed genetic structure, demographic history, and defined a framework for the coalescent simulations used in biogeographic hypothesis testing temporal and spatial co-variance. Our analyses suggested shared phylogeographic breaks in areas corresponding to the SMS populations, and between the main montane systems in Mesoamerica, with the Central Valley of Oaxaca and the Nicaragua Depression being the most frequently shared breaks among analyzed taxa. Nevertheless, dating analyses and divergence patterns observed were consistent with the hypothesis of broad vicariance across Mesoamerica derived from mechanisms operating at distinct times across taxa in the SMS. Conclusions Our study provides a framework for understanding the evolutionary origins and historical factors enhancing speciation in well-defined regions within Mesoamerica, indicating that the evolutionary history of extant biota inhabiting montane forests is complex and often idiosyncratic.

Abstract
Osgoodomys banderanus is a recognized and endemic rodent species of western Mexico, an area known for its high biodiversity and number of endemisms. Phylogeographical relationships within this taxon were analyzed based on mitochondrial (ND3, tRNA-Arginine, ND4L and partial ND4) and nuclear (GHR) nucleotide sequences. We obtained a total of 112 samples from 22 localities, covering the complete distribution of the species. Phylogenetic analyses using Maximum Likelihood and Bayesian inference confirmed that Osgoodomys is a monophyletic group. In addition, phylogenetic and phylogeographic analyses detected three major clades, which do not coincide with the recognized subspecies of O. banderanus. The genetic lineages detected are the western clade (Nayarit, Jalisco and northern Colima), the central clade (Colima, Michoacán, and northern Guerrero) and the eastern clade (central and southern Guerrero). Genetic distances among clades (5-9%) and nucleotide substitutions (30-88) among haplogroups were high, especially in the southern group. Mountain ranges such as the Transmexican Volcanic Belt and the Sierra Madre del Sur, as well as the Balsas River act as geographical barriers for Osgoodomys. Our results suggest the presence of three independent species, which need to be characterized morphologically to confirm our hypothesis.

Abstract
Phanaeusbravoensissp. n. is described from the coniferous-oak forests in the state of Guerrero, and P.huicholsp. n. from coniferous-oak forests and cloud forests in Jalisco and Nayarit. The new species are closely related to P.halffterorum and P.zoque respectively. Morphological trait combination, geographic distribution, and trophic habits show important differences among the studied species. A distribution map and an updated key to separate the species are included.

Abstract
We describe range-wide phylogeographic variation in the Black-headed Grosbeak (Pheucticus melanocephalus), a songbird that is widely distributed across North American scrublands and forests. Phylogenetic analysis of mitochondrial DNA (mtDNA, n=424) revealed three geographically structured clades. One widespread clade occurs throughout the Rocky Mountains, Great Basin, and Mexican Plateau, a second clade is found on the Pacific coast and in coastal ranges; and, a third in the Sierra Madre del Sur of Oaxaca and Guerrero. Some geographical structuring occurs in Mexican Plateau and Sierra Madre Oriental mtDNA clade, presumably because these populations have been more stable over time than northern populations. Multiple mitochondrial groups are found sympatrically in the Okanogan River Valley in Washington, the eastern Sierra Nevada, and the Transvolcanic Belt across central Mexico, indicating that there is a potential for introgression. Analyses of 12 nuclear loci did not recover the same geographically structured clades. Population analyses show high levels of gene flow in nucDNA from the Interior into the Sierra Madre del Sur and Pacific population groups, possibly indicating expansion of the Interior population at the expense of peripheral populations.

Abstract
The dominant controls on global paleomonsoon strength include summer insolation driven by precession cycles, ocean circulation through its influence on atmospheric circulation, and sea-surface temperatures. However, few records from the summer North American Monsoon system are available to test for a synchronous response with other global monsoons to shared forcings. In particular, the monsoon response to widespread atmospheric reorganizations associated with disruptions of the Atlantic Meridional Overturning Circulation (AMOC) during the deglacial period remains unconstrained. Here, we present a high-resolution and radiometrically dated monsoon rainfall reconstruction over the past 22,000 y from speleothems of tropical southwestern Mexico. The data document an active Last Glacial Maximum (18-24 cal ka B.P.) monsoon with similar δ(18)O values to the modern, and that the monsoon collapsed during periods of weakened AMOC during Heinrich stadial 1 (ca. 17 ka) and the Younger Dryas (12.9-11.5 ka). The Holocene was marked by a trend to a weaker monsoon that was paced by orbital insolation. We conclude that the Mesoamerican monsoon responded in concert with other global monsoon regions, and that monsoon strength was driven by variations in the strength and latitudinal position of the Intertropical Convergence Zone, which was forced by AMOC variations in the North Atlantic Ocean. The surprising observation of an active Last Glacial Maximum monsoon is attributed to an active but shallow AMOC and proximity to the Intertropical Convergence Zone. The emergence of agriculture in southwestern Mexico was likely only possible after monsoon strengthening in the Early Holocene at ca. 11 ka.
