Is the Fynbos Biome Especially Susceptible to Invasion by Alien Plants? A Re-analysis of Available Data
نویسندگان
چکیده
Floristic analyses do not support the hypothesis that the fynbos biome is more susceptible to alien plant invasions than are other South African biomes. Current levels of infestation, as indicated by vegetation surveys, indicate that the fynbos is more severely invaded than the other biomes. Hypotheses that have been proposed to explain the invasion of the fynbos by alien plants are listed. Virtually no critical testing of these hypotheses has been conducted. It is suggested thatfuture research should concentrate on defining the roles of anthropogenic disturbance, physiological competition and predation in determining the outcome of the competitive interaction between alien and indigene.

Question: How can vegetation gradients be described in riparian zones located in a species-rich mountain range and how do these gradients explain the variation found in the vegetation? Location: Hottentots Holland Mountains, Western Cape, South Africa. Methods: Three gradients (geographic, longitudinal, lateral) were defined to describe the complex vegetation patterns found here. The gradients ...
متن کاملRelease from belowground enemies and shifts in root traits as interrelated drivers of alien plant invasion success: a hypothesis
Our understanding of the interrelated mechanisms driving plant invasions, such as the interplay between enemy release and resource-acquisition traits, is biased by an aboveground perspective. To address this bias, I hypothesize that plant release from belowground enemies (especially fungal pathogens) will give invasive plant species a fitness advantage in the alien range, via shifts in root tra...
