The phrase "alien ecosystems" is correct and usable in written English.
It can be used to describe ecosystems that are not native to a particular area, often referring to species that have been introduced to a new environment.
Example: "The introduction of non-native species has led to the disruption of local flora and fauna, creating alien ecosystems that threaten biodiversity."
Alternatives: "foreign ecosystems" or "exotic ecosystems".
Beckett made a genuinely alien ecosystem, explored how stories and histories mutate and change – the Eden dwellers know about a conflict between the Germ Man and the Juice, for example – and formed a distinctive linguistic world, with words doubled as intensifiers, a range of slang terms (such as "do" for kill, and "slip" for sex) and some profoundly inventive oaths.
We pitched camp in a clearing, ate a lot of Spam and mangos, drank hot cola, and learned how to survive in an alien ecosystem.
Applications of monocultures of hybrids and sometimes alien species, and simple ecosystems of plants and microorganisms are feasible but difficult to apply in some cases.
Multidisciplinary knowledge on the impact caused by invasive alien species (IAS) on ecosystems is crucial for guiding policy makers in the adoption of sustainable management measures.
Naval trade traffic becomes intense, and invasions of islands from the mainland are already common, and they result in the beginning of the introduction of alien species in those ecosystems.
By identifying the functional role of alien invasive species in degraded ecosystems, conservationists have sparked a debate on the role of novel ecosystems in conservation (Hobbs et al. 2009; Kueffer and Kaiser-Bunbury 2014).
Forest edges have been long recognized as the first landscape elements to be invaded by alien plant species in forest ecosystems.
Therefore, the appropriate control and management of bush encroachment and alien plant invasions can restore ecosystems services and enhance the provision of timber and non-timber products to society.
To date, approaches to predict invasion patterns in response to anthropogenic global change have focused on (i) the extent of novel ecosystems, and (ii) alien species richness.
A good way to check hypotheses explaining the invasion of ecosystems by exotic plants is to compare alien and native congeneric species.
