REV IEW AND SYNTHESES Eight questions about invasions and ecosystem functioning
*Correspondence: E-mail: [email protected] Abstract I pose eight questions central to understanding how biological invasions affect ecosystems, assess progress towards answering those questions and suggest ways in which progress might be made. The questions concern the frequency with which invasions affect ecosystems; the circumstances under which ecosystem change is most likely; the f...
متن کاملCharacterizing ecosystem-level consequences of biological invasions: the role of ecosystem engineers
Invasions by exotic species represent both threats to ecosystems as well as opportunities to learn more about them. Among the invaders that will have the largest impacts are those that directly modify ecosystems and thus have cascading effects for resident biota. Exotics can affect ecosystems by altering system-level flows, availability, or quality of nutrients, food, and physical resources (e....
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 , 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...
متن کاملRecognition systems and biological invasions
Recognition systems are an integral component of the biology of all species. The highly tuned nature of many recognition systems may make them particularly sensitive to environmental and genetic changes. In this review, we examine how biological invasions influence recognition systems and discuss how plasticity in recognition systems may contribute to the success of species in new environments....
