| Ten plants were collected from both a turlough basin population and a damp ruderal population bimonthly for a year. |
|
| Most of the non-endemic species within this group have adapted to ruderal areas, while none of the endemics occupies this kind of habitat. |
|
| Many, but not all, of these alien species persist as ruderal or agrestal weeds. |
|
| The low nutrient availability may allow stress-tolerant species to coexist with more ruderal species. |
|
| These could be due to the fact that most of the non-endemic species within this group have adapted to ruderal areas, while none of the endemics occupies this kind of habitat. |
|
| Plants easily adapt to a multitude of agrestal and ruderal habitats. |
|
| These populations are morphologically distinct from the more typical ruderal form which often occurs in close proximity in surrounding pastureland. |
|
| Most of the introduced woody species exist in ruderal habitats. |
|
| In these treatments, habitats listed for this grass include marshes, bottomland forests, river banks, exposed bars and shores, and open ruderal areas. |
|
| The term ruderal means growing in waste places or rubbish, and is descriptive of the habitat of perhaps the majority of weeds. |
|
| We have already spotted other very rare species in the area, including the ruderal bumblebee and the redshanked carder bee. |
|
| The earliest successional species were common ruderal annuals followed by perennials, Solidago altissima and Symphyotrichum pilosum. |
