We attributed this decrease to human activities associated with development of the park's infrastructure causing dispersal of animals. |
Experiments suggest that arborescent lycopsid propagules had a rather limited dispersal range. |
In fact, the seed dispersal rate was notably higher when capsules dried after a rainy period. |
As in natural dispersal, we used samaras of the trees, and cleaned, dry shrub seeds. |
The gain was in authorial sympathy and readerly involvement, as well as the dispersal of interpretive possibilities. |
Many of them flourish in a broad range of habitats, and nearly all of them are adapted for wide dispersal. |
