  Biological invasions have steadily increased over recent centuries. However, we still lack a clear expectation about future trends in alien species numbers. In particular, we do not know whether alien species will continue ...

• Characteristics of native predators are more important than those of alien prey in determining the success of biotic resistance in marine systems 

  Skein, L.; Alexander, M.E.; Robinson, T.B. (2021)

  Predator-driven biotic resistance is known to be more effective in marine systems than in terrestrial and freshwater environments. However, there is little consensus about when such resistance can be expected to succeed ...

• Vegetation and soil recovery following Eucalyptus grandis removal in Limpopo Province, South Africa 

  Ruwanza, S. (2021)

  South African terrestrial ecosystems are invaded by hundreds of alien plant species, and large-scale clearing based on the passive restoration assumption that cleared areas will recover unaided is underway. This study ...

  Human introductions of species beyond their natural ranges and their subsequent establishment are defining features of global environmental change. However, naturalized plants are not uniformly distributed across phylogenetic ...

• Toad-kill: Prey diversity and preference of invasive guttural toads (Sclerophrys gutturalis) in Mauritius 

  Baxter-Gilbert, J.; Florens, F.B.V.; Baider, C.; Perianen, Y.D.; Citta, D.S.; Appadoo, C.; Measey, J. (2021)

  The invertebrate communities of Mauritius host a high degree of endemism, but are also imperilled by an array of factors, including invasive predators. Since their introduction in 1922, guttural toads (Sclerophrys gutturalis) ...

• How competitive intransitivity and niche overlap affect spatial coexistence 

  Yang, Y.Q.; Hui, C. (2021)

  Competitive intransitivity is mostly considered outside the main body of coexistence theories that rely primarily on the role of niche overlap and differentiation. How the interplay of competitive intransitivity and niche ...
