Abstract

Abstract Scabiosa atropurpurea is an invasive herbaceous plant now found in 9 states, including 19 counties in north-central Texas and 2 counties in adjacent Oklahoma. Scabiosa atropurpurea forms dense colonies along roadsides and in old agricultural fields and poses a threat to native and improved grasslands. We evaluated the response of S. atropurpurea to mowing and prescribed fire. Mowing caused a marked increase in the density of S. atropurpurea. However, S. atropurpurea declined when there was no management at all and when exposed to growing season fire. Mowing of S. atropurpurea during roadside management and other management contexts leads to persistence and spread of this species. In complex communities, this plant will likely decline and growing season fires may help accelerate these declines.

刈割和规定火对德克萨斯州中北部一入侵种群的影响

摘要赤藓是一种入侵草本植物，目前在9个州发现，包括德克萨斯州中北部的19个县和邻近的俄克拉荷马州的2个县。萎缩小赤藓沿着路边和古老的农田形成密集的群落，对原生和改良的草原构成威胁。我们评估了S.atropurpurea对割草和规定火灾的反应。割草使萎缩葡萄的密度显著增加。然而，当完全没有管理时，当暴露在生长季节的火灾中时，S.atropurpurea就衰落了。在路边管理和其他管理环境中割草导致该物种的持续存在和传播。在复杂的社区中，这种植物可能会衰退，生长季节的火灾可能会加速这种衰退。

期刊介绍： The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
