Species invasions exceed extinctions on islands worldwide: a comparative study of plants and birds.
Species richness is decreasing at a global scale. At subglobal scales, that is, within any defined area less extensive than the globe, species richness will increase when the number of nonnative species becoming naturalized is greater than the number of native species becoming extinct. Determining whether this has occurred is usually difficult because detailed records of species extinctions and...
متن کاملBiological invasions
Where do basal bodies come from? The basal body is considered to be a self-replicating organelle. In a process that is not yet completely understood, the daughter basal body is assembled adjacent and orthogonal to the mother organelle. Although this was long speculated to be a templated assembly process, it is likely that the mother basal body acts as the site where components required for asse...
متن کاملBiological Invasions on Oceanic Islands : Implications for Island Ecosystems and Avifauna
Biological invasions present a global threat to biodiversity. but oceanic islands are the systems hardest hit by invasions. Islands are generally depauperate in species richness, trophic complexity, and functional diversity relative to comparable mainland ecosystems. This situation results in low biotic resistance to invasion and many empty niches for invaders to exploit. It also results in isl...
متن کاملImpacts of biological invasions on disturbance regimes.
Human management activities have altered the frequency and intensity of ecosystem disturbance often with enormous impacts on landscape structure and composition. One additional and under-appreciated way in which humans have altered disturbance regimes is through the introduction of invasive non-native species, themselves capable of modifying existing disturbance regimes or introducing entirely ...
متن کاملBiological Invasions , Biological Diversity and Trade
The opening of new markets or trade routes has resulted in the deliberate or accidental introduction of new species, while the growth in the volume of trade has increased the frequency of species introductions. We model the connection between landscape heterogeneity, resource extraction, the level of biodiversity, and the level of trade. We show that the invasion risks of trade reduce the socia...
