Abstract

Biodiversity loss is happening at an unprecedented rate, and invasive species are one of the main contributors to the global biodiversity decline. Invasive species are alien (non-native) organisms that become overpopulated and cause environmental harm to the native environment. For example, a recent global meta-analysis shows that 30 invasive predator species have been linked to the extinction or endangerment of 738 vertebrate species, accounting for 58% of all bird, mammal, and reptile extinctions. For effective biology conservation, some questions are worth answering: Do invasive species have any invasion limits? Or are they capable of invading habitats significantly different from their native environment due to their strong adaptability?
