The number of sunken seeds of the non-invasive alien species (‘NIAS’) I. balfourii and the invasive alien species (‘IAS’) I. glandulifera in the still and turbid water experiments
| Phase | I. balfourii (NIAS) | I. glandulifera (IAS) | ||
|---|---|---|---|---|
| Istria (YP) | Insubria (OP) | Cracow (YP) | Insubria (OP) | |
| Day 0 | 163 | 199 | 111 | 28 |
| Day 11/12 | 164 | 201 | 127 | 42 |
| Day 62/64 | 165 | 215 | 126 | 43 |
| Second 20 | 99 | 99 | 77 | 44 |
| Second 960 | 100 | 99 | 88 | 61 |
| Second 12,480 | 100 | 99 | 99 | 86 |
The seeds were collected from populations differing in age: ‘YP’ means younger population, and ‘OP’ means older population. The three phases of the still (“Day 0”, “Day 11/12”, and “Day 62/64”) and turbid water experiments (“Second 20”, “Second 960”, “Second 12,480”; see “Materials and methods”) are shown
