The aquarium trade is an important and rapidly growing vector for introduced species in the United States. We examined this by surveying pet stores San Francisco Bay–Delta region to compile a list of fish commonly stocked. identified which these might be able survive Bay–Delta, investigated store representatives' knowledge attitudes about biological invasions. A restrictive analysis using conservative estimates temperature tolerances environmental conditions found that local includes 5 can...
Although prevention is the most cost-effective way to avoid enormous expenses associated with plant invasions, invasive plants continue be imported as trade commodities for horticultural use. With very little government regulation of imports plants, efforts have turned toward fostering voluntary initiatives encourage self-regulation by horticulture trade. Our study takes first step evaluating potential success these initiatives. We conducted a survey nursery professionals gauge their...
The early phases of biological invasions are poorly understood. In particular, during the introduction, establishment, and possible lag phases, it is unclear to what extent evolution must take place for an introduced species transition from established expanding. this study, we highlight three disparate data sources that can provide insights into evolutionary processes associated with invasion success: control organisms, horticultural introductions, natural history collections. All...
In mountain regions around the world, downhill ski areas represent a significant source of anthropogenic disturbance while also providing recreation and revenue. Ski‐run creation always results in some level disturbance, but intensity varies greatly with construction method. Ski runs may be established either by clearing (cutting removing tall vegetation) or then machine‐grading (leveling soil surface heavy equipment). To quantify how these different intensities initial affect ecosystem...
Summary The importance of site history (including initial disturbance intensity and propagule arrival) in determining successional trajectories is a key theoretical applied line research ecology. Abandoned ski slopes provide an opportunity to study processes following differing intensities. Some are graded with heavy equipment when constructed (‘graded’, severe disturbance), while others simply cleared tall woody vegetation (‘cleared’, lesser disturbance). In blocked chronosequence abandoned...
