Biological 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....
متن کاملSpace race functional responses.
We derive functional responses under the assumption that predators and prey are engaged in a space race in which prey avoid patches with many predators and predators avoid patches with few or no prey. The resulting functional response models have a simple structure and include functions describing how the emigration of prey and predators depend on interspecific densities. As such, they provide ...
متن کاملCan biological invasions induce desertification?
A common form of land degradation at the desert margins involves the rapid encroachment of woody plants into historic grasslands and the acceleration of soil erosion as a result of the loss of grass cover (Archer, 1989; Schlesinger et al., 1990). The conversion of perennial grasslands into desert scrublands has been documented worldwide (Van Auken, 2000; Ravi, 2008) and has important implicatio...
