However, understanding how these factors specifically impact the genealogical structure of dominant Gramineous species in the Qinghai–Tibet Plateau (QTP) remains a subject of investigation. Elymus sibiricus L. (Gramineae), indigenous to the QTP and widely distributed in Eurasia, exhibits remarkable environmental adaptation and phenotypic diversity, making it an ideal candidate for phylogeographic studies. Based on the analysis of 175 complete chloroplast genome sequences, our results indicated that the ancestors of E. sibiricus originated from the QTP and underwent a complex migration history. After the speciation of E. sibiricus , several geo‐groups exhibited independent differentiation, showing minimal gene flow among them. The current phylogeographic patterns of E. sibiricus are a result of frequent climate alternations and the cold climate during the Quaternary glacial, as well as the presence of several geographical barriers that have restricted the gene flow among different geo‐groups. Our research has revealed for the first time that E. sibiricus has a multilineage origin, and its maternal donors are not limited to a single species. Furthermore, the high quality and mapping depth of the variant file provided reliable data for analyzing the patterns based on raw sequencing data. These findings enhance our understanding of the relationship between plant differentiation and climatic and geographical factors of Eurasia.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135537290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With rapid economic development of Hainan, biodiversity is increasingly at risk. Determining the spatial patterns of plant diversity in Hainan and explaining the drivers behind plant diversity are important considerations in assessing and maximizing the effectiveness of national parks, such as the newly designated Hainan Rainforest National Park. We assessed phylogenetic diversity patterns, and species richness using 106 252 georeferenced specimen records and a molecular phylogeny of 3792 native plant species. Based on phylogenetic range‐weighted turnover metrics, we divided Hainan flora into four major floristic units. The Grade of Membership model was used to further verify the four units, and to understand their boundaries and the internal structure of each floristic unit. Finally, the best combination model was used to explore the driving mechanisms underlying the division. Our results reveal that central Hainan is the most important hotspot for plant endemism and diversity, followed by the southern area. Environmental energy is the main factor determining the spatial patterns of native plant diversity on the island, and accessibility has the greatest impact on native plant diversity among social factors. We explore patterns of spatial phylogenetics and biogeography to identify potential priorities for management and conservation drivers of plant diversity patterns across Hainan, to provide the basis for the effective protection of native plant diversity and the improvement of national parks of Hainan Island.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136130072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some species produce the neurotoxin domoic acid. Herein, two new Pseudo‐nitzschia species were described from Chinese coastal waters and the South China Sea after combining morphological and molecular data, together with biogeographical traits. Pseudo‐nitzschia punctionis sp. nov. was similar to Pseudo‐nitzschia bipertita morphologically, but differed in poroid structure, which was undivided in P. punctionis but divided in two sectors in P. bipertita. This difference corresponded to the presence of two hemicompensatory base changes (HCBCs) in the secondary structure of internal transcribed spacer 2. Pseudo‐nitzschia polymorpha sp. nov. was sister to Pseudo‐nitzschia limii phylogenetically, but distinct by the various shapes of perforations on the valve and copula, which was supported by four HCBCs. In a metabarcoding analysis, multiple new ribotypes were identified within the two new species, and intraspecific genetic divergences were analyzed. Metabarcoding data revealed that P. punctionis had a broader temperature range (12.9–30.5 °C) than P. polymorpha (22.3–30.5 °C). Within the two new species, different traits were found among the amplicon sequence variants regarding temperature and biogeography, representing different microevolutionary directions under environmental selection. The two new species had different biogeographical traits when compared to their closely related species. Domoic acid was detected in strains of P. punctionis at a concentration of 13.5–17.7 fg/cell, but the toxin was not found in strains of P. polymorpha. A combination of characters based on laboratory strains and field metabarcoding data provided more data for delimiting Pseudo‐nitzschia species and gave new insights into their diversity and biogeography.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"52 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87993722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two distinct lineages (JPN1 and JPN2) of panarctic Daphnia cf. pulex sensu Hebert (1995), invaded independently into Japan from North America, provide an excellent opportunity to test this hypothesis because the earlier invader JPN1 has a lower dN/dS ratio than JPN2. Therefore, we examined phenotypic variations in fitness‐related traits, including digestive, life‐history, and morphological traits, among several genotypes within these two lineages. We found that phenotypic variations were smaller within the JPN1 lineage than within the JPN2 lineage. Furthermore, within‐lineage variation of the phenotypic plasticity to changing food levels was smaller in the JPN1 lineage than in the JPN2 lineage. These results support the hypothesis that the JPN1 lineage has been more efficiently subjected to negative selection. However, the magnitude of the phenotypic plasticity of these traits was, on average, at the same level between the JPN1 and JPN2 lineages and its direction differed among genotypes of these lineages, suggesting that the JPN2 genotypes might have exploited niches that were different from those of the JPN1 genotypes.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"32 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74283134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its wide distribution range and current patterns of genetic variation have been influenced by Quaternary climatic oscillations and the demographic processes connected to them. In order to better understand the relationship between evolutionary history and demographic factors in a widespread species with a large genome, we used the single‐nucleotide polymorphism (SNP) array to genotype thousands of SNP markers across 62 natural populations (N = 686 trees) of Scots pine in Eurasia. This provides the largest range‐wide SNPs' genetic diversity assessment of Scots pine to date. Our findings show evidence of past admixture events between genetic clusters that were retained despite the potential for effective pollen‐mediated gene flow across the species' distribution range. We also examined the contemporary population structure of the species and analyzed the range‐wide genetic diversity patterns. Phylogenetic analyses and demographic modeling suggest that the observed divergence patterns between genetic lineages likely predate the last glaciation events. Two of the most distinctive groups are represented by trees from the eastern parts of Fennoscandia and Eastern Russia, which have remained separated since the mid‐Pleistocene. The patterns of genetic variation also confirm the dual colonization of Fennoscandia and the existence of an admixture zone in Central Europe that was formed during multiple waves of postglacial recolonization. This study provides insights into the genetic relationships of Scots pine populations from Europe and Asia and offers a more comprehensive understanding of the species' history.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"87 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76819159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regions of elevated differentiation, referred to as genomic islands, could be shared among closely related species (shared islands) or specific to a lineage (lineage‐specific islands). Shared islands are typically assumed to result from background selection. However, simulations and empirical studies have suggested that positive selection contributes to both shared and lineage‐specific islands. Here, we utilized comparative population genomics to examine the contributions of different evolutionary processes to patterns of genetic differentiation when gene flow and incomplete lineage sorting are minimal. We used whole‐genome resequencing data for 135 individuals from four oak species, including two independent species pairs, Quercus variabilis Blume and Quercus acutissima Carruth. in the subgenus Cerris, and Quercus dentata Thunb. and Quercus griffithii Hook.f. & Thomson ex Miq. in the subgenus Quercus. We found that both shared and subgenus‐specific islands were caused by positive selection, including selective sweeps in current populations and in their most recent common ancestors. Moreover, the recombination rate was a better predictor of genomic differentiation than gene density. Overall, our results reveal that recombination and positive selection impacted genomic differentiation considerably and provide a more precise grasp of how genomic islands formed in Quercus.","PeriodicalId":101317,"journal":{"name":"JOURNAL OF SYSTEMATICS AND EVOLUTION","volume":"56 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80195470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
