概括

这项研究确定了八种Geosmithia真菌物种,包括四种新物种,与南非的树皮甲虫有关. 它扩大了我们对南半球真菌生物多样性和宿主真菌关系的理解.

科学领域:

菌类学菌类学是指菌类学.
昆虫学昆虫学是一门学科.
生物多样性研究的研究.

背景情况:

属Geosmithia (Sordariomycetes) 经常与木虫一起发现,但在分类学和生态学上仍未得到充分研究,特别是在南半球.
之前在南非的调查发现了皮甲虫中的Geosmithia物种,但缺乏彻底的物种识别.

研究的目的:

隔离,识别和描述南非西开普省与树皮甲虫相关的Geosmithia物种.
重新检查以前从南非收集的Geosmithia标本.
为促进对Geosmithia属的分类学和生态学的理解做出贡献.

主要方法:

从南非西开普省的本土树木收集树皮甲虫.
隔离和识别相关的Geosmithia真菌.
对所有分离物体进行ITS区域的DNA测序,对子集进行BT,EF1a和RPB2的额外测序.

主要成果:

遗传学分析证实了四种已知的地质植物物种:G. flava,G. langdonii,G. omnicola和G. pumila.
鉴定并描述了四种新的Geosmithia物种:G. capensis,G. multisociorum,G. oroboidis和G. stellenboschiana. 这些物种包括:
G. multisociorum被确定为半球范围内的通用主义者,而G. oroboidis则特定于单一的南非甲虫宿主. G. capensis和G. stellenboschiana在南非表现出宿主特异性,但在其他地方分布更广泛.

结论:

这项研究显著扩大了南非Geosmithia已知的多样性,描述了四种新物种.
该研究强调了Geosmithia属内的不同程度的宿主和地理特异性.
这些发现为全球与树皮甲虫相关的Sordariomycetes真菌的分类学和生态学提供了关键数据.

关键词:

生物光学科的生物光学科.伪善的人是伪善的本土的土著居民.人类遗传学是一个学科.斯科利蒂娜 (Scolytinae) 是一个小鸟类.索尔达里奥米塞特斯 (Sordariomycetes) 是一种有毒的植物.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
