Genetic structure reveals a history of multiple independent origins followed by admixture in the allopolyploid weed Salsola ryanii
It has recently become clear that many invasive species have evolved in situ via hybridization or polyploidy from progenitors which themselves are introduced species. For species formed by hybridization or polyploidy, genetic diversity within the newly formed species is influenced by the number of independent evolutionary origins of the species. For recently formed species, an analysis of genet...
متن کاملRecent postglacial range expansion drives the rapid diversification of a songbird lineage in the genus Junco.
Pleistocene glacial cycles are thought to have played a major role in the diversification of temperate and boreal species of North American birds. Given that coalescence times between sister taxa typically range from 0.1 to 2.0 Myr, it has been assumed that diversification occurred as populations were isolated in refugia over long periods of time, probably spanning one to several full glacial c...
متن کاملTranscriptomic Shock Generates Evolutionary Novelty in a Newly Formed, Natural Allopolyploid Plant
New hybrid species might be expected to show patterns of gene expression intermediate to those shown by parental species. "Transcriptomic shock" may also occur, in which gene expression is disrupted; this may be further modified by whole genome duplication (causing allopolyploidy). "Shock" can include instantaneous partitioning of gene expression between parental copies of genes among tissues. ...
متن کاملEvidence for rapid ecological range expansion in a newly invasive plant
Little is known about how an introduced species may expand its ecological range, i.e. the set of local environmental conditions in which it can successfully establish populations. Delimiting this range of conditions is a methodological challenge, because it is impossible to sample all potential field locations for any species in a given region. Developing approaches to track ecological range ov...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
