Geographical and temporal patterns of diversification in bee hummingbirds (Mellisugini) were assessed with respect to the evolution migration, critical for colonization North America. We generated a dated multilocus phylogeny Mellisugini based on dense sampling using Bayesian inference, maximum-likelihood maximum parsimony methods, reconstructed ancestral states distributional areas framework migratory behavior parsimony, re-rooting methods. All phylogenetic analyses confirmed monophyly inclusion Atthis, Calothorax, Doricha, Eulidia, Mellisuga, Microstilbon, Myrmia, Tilmatura, Thaumastura. consists two clades: (1) South American species (including Tilmatura dupontii), (2) distributed Central America Caribbean islands. The second clade four subclades: Mexican (Calothorax, Doricha) (Archilochus, Calliphlox, Mellisuga) sheartails, Calypte, Selasphorus (incl. Atthis). Coalescent-based dating places origin mid-to-late Miocene, crown ages most subclades early Pliocene, subsequent splits Pleistocene.

Hepatozoon canis is a protozoan transmitted to dogs and other wild carnivores by the ingestion of ticks containing mature oocysts considered principal cause canine hepatozoonosis in world. Here, we examined ribosomal RNA 18S gene sequence variation determine genetic differences phylogeographic diversity H. from various geographical areas around world.We used 550 publicly available sequences 46 countries assess haplotype relationships, structure, indices, relationships among populations. We performed neutrality tests pairwise comparisons fixation index (FST) values between groups FST To whether populations are structured, analyses molecular variance (AMOVAs) spatial analysis (SAMOVA) were performed.The dataset yielded 76 haplotypes. Differentiation indicated that there no phylogeographical structure (GST = 0.302 ± 0.0475). Moreover, when samples grouped continents significant was obtained, meaning genetically differentiated. The AMOVA showed 57.4% explained within all locations treated as single group revealed population into two, three, four (FCT, p > 0.05), suggesting dispersal high. SAMOVA FCT for K 5.

Hybridization and differential introgression associated with environmental shifts in a mistletoe species complex

Scientific Reports, Journal Year: 2018, Volume and Issue: 8(1)

Published: March 29, 2018

Host specialization after host shifting is traditionally viewed as the pathway to speciation in parasitic plants. However, geographical and environmental changes can also influence parasite speciation, through hybridization processes. Here we investigated impact of past climatic fluctuations, environment, shifts on genetic structure patterns gene flow between Psittacanthus calyculatus P. schiedeanus, a Mesoamerican species complex. Using microsatellites (408 individuals), document moderate diversity but high differentiation widespread parental clusters, dry pine-oak forests schiedeanus cloud forests. Bayesian analyses identified third cluster, with admixture clusters areas xeric tropical levels migration rates following secondary contact. Coincidently associations these differ from those species, suggesting that played role shifts. Overall, observed geographic suggest populations could have entered distinct evolutionary pathway. The results provide evidence for highlights importance Pleistocene climate changes, habitat differences, potential history Neotropical mistletoes.

The state of Oaxaca is positioned in a rather unique biogeographical position with the highest diversity vascular plants Mexico. isolation xeric valleys surrounded by complex mountain ranges supplies an excellent opportunity to investigate influence Pleistocene events on species. To test for alternative hypotheses glacial refugia, we used sequences two chloroplast markers examine phylogeographic patterns endemic mistletoe species Psittacanthus auriculatus (Loranthaceae) across its known range and conducted ecological niche modeling (ENM) explore changes distribution through present, future, palaeo periods. Our results revealed groups corresponding individuals/populations from northern locations (western valleys), those southern localities at central Oaxaca. A significant genetic signal differentiation, demographic stability, contraction suitable habitat during Last Glacial Maximum predicted ENMs strongly supported scenario fragmentation Late Pleistocene.

Abstract Lycianthes moziniana (Solanaceae: Capsiceae) is a perennial herb with edible fruits that endemic to Mexico. Three varieties are recognized, all known in the Mexican Transition Zone. var. margaretiana grows Sierra Madre Oriental, whereas L. common along Trans-Mexican Volcanic Belt and Occidental. oaxacana found exclusively del Sur. The Zone complex geological, climatic biogeographical area, result of tectonic volcanic activity has promoted genetic divergence speciation. We determined variation structure moziniana. Using phylogeographical approaches, we described demographic history evolutionary processes leading its divergence. intergenic spacers rpl32-trnL ycf1 were sequenced for 133 individuals pertaining 15 populations. genealogical relationships analysed using haplotype networks. Finally, based on ecological niche models, inferred palaeodistribution during Pleistocene. differences haplogroups matched three varieties. Geological events facilitated these results. isolated populations Oriental Sur, while allowing migration Occidental, middle Holocene.
