The increased exchange of agricultural goods and people has unleashed the spread of alien species in the Caribbean. The Dominican Republic, as well, has been burdened with the introduction of dozens of alien species, including a substantial number with high invasive potential. Some of...
Our primary objectives were to identify high‐risk species and their introduction pathways, to detail the magnitude and mechanism of potential impacts, and, more broadly, to demonstrate the utility of horizon scanning. As a means to facilitate future horizon scans, we document the process...
(虽然并非所有物种都将成为入侵物种,但专家表示,有重要的工具可以mitigate它们的传播和影响,在此过程中保护和恢复生态系统)”以及第三段“The expert assessment found that there were a wide range of options to prevent the spread and impact of invasive species.(专家评估发现,有多种选择可以防止入侵物种的...
These odd characteristics became major assets after man started reshaping the surface of the earth, facilitating their spread. Invasion risk-assessment models, chiefly based on environmental match parameters, are unlikely to predict the dispersion of these (and probably many other) species, whose ...
The unifying characteristic of all invasive species is that they've been unnaturally introduced to their host environment. Therefore, the cause of invasive species is almost always humans. There are a variety of ways that humans transport species into new environments, both intentionally and unintentio...
One of the simplest ways to deal with invasive species is just to eat them. 没错! 对付入侵物种最简单的方法之一就是吃掉它们。 In this programme we’ll be hearing about initiatives in the UK and Belize that are trying to get people to improve things using their stomachs. 在本期节目中,...
Invasive speciesare defined as nonnative species that have been introduced by humans and have established and spread in their introduced range. These last two characteristics – establishment and spread – imply impacts on native communities, although impacts have been quantified for only a small propor...
