Abstract

Biodiversity loss is currently one of the most important societal concerns worldwide, and it is caused mainly by habitat loss and fragmentation, biological invasion, and climate change (Vitousek et al. 1996, Newbold et al. 2015, Bellard et al. 2016). Introduced species can have positive effects on human well-being, especially when used for livelihoods benefits (Shackleton et al. 2019). However, introduced species become invasive when they disrupt ecosystem processes by negatively affecting native species through direct, indirect or apparent competition, predation, habitat modification, and alteration of nutrient and water cycles (Long 2003, Mooney et al. 2005, Clout and Rusell 2007, Bellard et al. 2016).
