Invasion patterns of ground-dwelling arthropods in Canarian laurel forests

摘要: Patterns of invasive species in four different functional groups ground-dwelling arthropods (Carnivorous ground dwelling beetles; Chilopoda; Diplopoda; Oniscoidea) were examined laurel forests the Canary Islands. The following hypotheses tested: (A) increasing richness is connected with decreasing invasibility as predicted by Diversity–invasibility hypothesis (DIH); (B) disturbed or anthropogenically influenced habitats are more sensitive for invasions than natural and undisturbed habitats; (C) climatic differences between forest sites do not affect rate invasibility. A large proportion invasives (species abundances) was observed most studied arthropod groups. However, we did find any support DIH based on Regarding impact extrinsic factors ‘disturbance’ ‘climate’ invasion patterns, found considerable Whereas ‘disturbance parameters’ played a minor role only affected relative abundances centipedes (positively) millipedes (negatively), ‘climate significantly linked pattern detritivores. Interactions native invading have been thus far, but cannot completely be excluded.
