概括

本地 Monomorium chinense 和 Nylanderia bourbonica 对入侵的红色进口火 (Solenopsis invicta) 呈现出侵略性. 这些本地物种显示出在某些息地控制S. invicta的潜力,特别是在实施侵入性控制措施后.

科学领域:

生态生态学生态生态学
侵袭性物种管理侵袭性物种管理
昆虫学昆虫学是一门学科.

背景情况:

本地是潜在的生物控制代理对入侵物种,如红色进口火 (Solenopsis invicta).
现有的关于本土抑制S. invicta的研究是有限的,主要是基于行为观察.

研究的目的:

为了评估本地 (Monomorium chinense, Nylanderia bourbonica, Iridomyrmex anceps) 对Solenopsis invicta.的攻击性和死亡率.
调查S. invicta.所占息地的本土的丰富性,季节动态和空间分布.

主要方法:

实验室实验评估本地对S. invicta.的侵略性和死亡率.
现场调查使用诱瓶来确定各种息地 (林地,绿地带,草原,农田) 的本土丰度.
在S. invicta控制之前和之后,季节性地和空间地监测本地种群.

主要成果:

在实验室条件下,Monomorium chinense和Nylanderia bourbonica表现出侵略性,并导致S. invicta在实验室条件下显著死亡;Iridomyrmex anceps没有.
在所有研究息地中都发现了M. chinense和N. bourbonica,在绿地带和草原中丰富度更高.
在被入侵的草原上,M. chinense和N. bourbonica种群在S. invicta控制后扩大了它们的范围.

结论:

蒙诺 (Monomorium chinense) 和尼兰德里亚 (Nylanderia bourbonica) 具有抑制Solenopsis invicta入侵的潜力.
这些本土的有效性与它们的丰富性和在特定息地存在有关,控制S. invicta有助于本土的传播.

Hypothesis: Accept or Fail to Reject?

Hypothesis: Accept or Fail to Reject?

The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Limits to Natural Selection

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.
