abstract = {Oak hybridization have important effects on the structure of herbivorous insect communities and associated natural enemies. We tested the effects of hybridization between Q. magnoliifolia and Q. resinosa on insect gallers trophic networks and their parasitoids. We characterized the genotypes of 35 individuals of Q. magnoliifolia, 30 of Q. resinosa, and 57 hybrids using eight nuclear microsatellite markers. We collected 6,798 galls from the oak hybrid complex distributed in 33 gall morphospecies on Q. magnoliifolia, 28 on Q. resinosa, and 42 on hybrid oaks. Galler-parasitoid networks were realized by 21 gall morphospecies and 21 parasitoid species for Q. magnoliifolia; 16 gall morphospecies and 30 parasitoid species for Q. resinosa; and 25 gall morphospecies and 23 parasitoid species for hybrids. Plant-galler networks were different among three oak groups, having the hybrid network higher values of diversity of interactions, nestedness and modularity and lower values of specialization than Q. magnoliifolia and Q. resinosa networks. Hybrid network of gallers and parasitoids had higher diversity of interactions, connectance and generality and lower modularity than Q. magnoliifolia and Q. resinosa networks. Hybrids are more vulnerable to insect galler incidence having low pressure by parasitoids, which allow more gall incidence in hybrid plants. Our study corroborated that hybridization generates changes in oak genetic composition influencing insect gallers trophic networks and their parasitoids. Our findings are also consistent with the rule of genetic similarity which suggest a relationship between plant genetics and the associated arthropod community, where genetically similar plants support similar arthropod communities.},

abstract = {The climatic and geological changes that occurred during the Quaternary, particularly the fluctuations during the glacial and interglacial periods of the Pleistocene, shaped the population demography and geographic distribution of many species. These processes have been studied in several groups of organisms in the Northern Hemisphere, but their influence on the evolution of Neotropical montane species and ecosystems remains unclear. This study contributes to the understanding of the effect of climatic fluctuations during the late Pleistocene on the evolution of Andean mountain forests. First, we describe the nuclear and plastidic DNA patterns of genetic diversity, structure, historical demography, and landscape connectivity of Quercus humboldtii, which is a typical species in northern Andean montane forests. Then, these patterns were compared with the palynological and evolutionary hypotheses postulated for montane forests of the Colombian Andes under climatic fluctuation scenarios during the Quaternary. Our results indicated that populations of Q. humboldtii have high genetic diversity and a lack of genetic structure and that they have experienced a historical increase in connectivity from the last glacial maximum (LGM) to the present. Furthermore, our results showed a dramatic reduction in the effective population size followed by an expansion before the LGM, which is consistent with the results found by palynological studies, suggesting a change in dominance in Andean forests that may be related to ecological factors rather than climate change.},

abstract = {The Mexican highlands are areas of high biological complexity where taxa of Nearctic and Neotropical origin and different population histories are found. To gain a more detailed view of the evolution of the biota in these regions, it is necessary to evaluate the effects of historical tectonic and climate events on species. Here, we analyzed the phylogeographic structure, historical demographic processes, and the contemporary period, Last Glacial Maximum (LGM) and Last Interglacial (LIG) ecological niche models of Quercus castanea, to infer the historical population dynamics of this oak distributed in the Mexican highlands. A total of 36 populations of Q. castanea were genotyped with seven chloroplast microsatellite loci in four recognized biogeographic provinces of Mexico: the Sierra Madre Occidental (western mountain range), the Central Plateau, the Trans-Mexican Volcanic Belt (TMVB, mountain range crossing central Mexico from west to east) and the Sierra Madre del Sur (SMS, southern mountain range). We obtained standard statistics of genetic diversity and structure and tested for signals of historical demographic expansions. A total of 90 haplotypes were identified, and 29 of these haplotypes were restricted to single populations. The within-population genetic diversity was high (mean hS = 0.72), and among-population genetic differentiation showed a strong phylogeographic structure (NST = 0.630 > GST = 0.266; p <.001). Signals of demographic expansion were identified in the TMVB and the SMS. The ecological niche models suggested a considerable percentage of stable distribution area for the species during the LGM and connectivity between the TMVB and the SMS. High genetic diversity, strong phylogeographic structure, and ecological niche models suggest in situ permanence of Q. castanea populations with large effective population sizes. The complex geological and climatic histories of the TMVB help to explain the origin and maintenance of a large proportion of the genetic diversity in this oak species.},

abstract = {The tree of life is highly reticulate, with the history of population divergence emerging from populations of gene phylogenies that reflect histories of introgression, lineage sorting and divergence. In this study, we investigate global patterns of oak diversity and test the hypothesis that there are regions of the oak genome that are broadly informative about phylogeny. We utilize fossil data and restriction-site associated DNA sequencing (RAD-seq) for 632 individuals representing nearly 250 Quercus species to infer a time-calibrated phylogeny of the world's oaks. We use a reversible-jump Markov chain Monte Carlo method to reconstruct shifts in lineage diversification rates, accounting for among-clade sampling biases. We then map the > 20 000 RAD-seq loci back to an annotated oak genome and investigate genomic distribution of introgression and phylogenetic support across the phylogeny. Oak lineages have diversified among geographic regions, followed by ecological divergence within regions, in the Americas and Eurasia. Roughly 60% of oak diversity traces back to four clades that experienced increases in net diversification, probably in response to climatic transitions or ecological opportunity. The strong support for the phylogeny contrasts with high genomic heterogeneity in phylogenetic signal and introgression. Oaks are phylogenomic mosaics, and their diversity may in fact depend on the gene flow that shapes the oak genome.},
