Seed mass, dispersal and establishment in Carduus thistles

19 The negative correlation between dispersal and establishment appears to be well documented 20 in the plant literature; smaller seeds tend to disperse better but germinate less well, and 21 produce smaller seedlings. However, because dispersal capacity is often quantified using 22 proxies, such as the settling velocity of wind-dispersed seeds, little is known about the exact 23 shape of this ...

Spatial dynamics of invasive Carduus thistles

Managing invasive species is inherently a spatial problem, even though the application of management is local. For efficient management of invasive species, we must therefore understand their spatial population dynamics. Once key demographic and dispersal rates are studied in detail, spatial population models can be constructed and utilized to evaluate the impact of various management options. ...

Landscape connectivity and seed dispersal characteristics inform the best management strategy for exotic plants.

Exotic plant invasions have triggered environmental and economic problems throughout the world. Our ability to manage these invasions is hindered by the difficulty of predicting spread in fragmented landscapes. Because the spatial pattern of invasions depends on the dispersal characteristics of the invasive species and the configuration of suitable habitat within the landscape, a universal mana...

Are Introduced Species Better Dispersers Than Native Species? A Global Comparative Study of Seed Dispersal Distance

We provide the first global test of the idea that introduced species have greater seed dispersal distances than do native species, using data for 51 introduced and 360 native species from the global literature. Counter to our expectations, there was no significant difference in mean or maximum dispersal distance between introduced and native species. Next, we asked whether differences in disper...
