“…This may be the case in streams and shallow, stagnant waters (Sand-Jensen et al 1992;Weisner, Graneli & Ekstam 1993). However, seedlings from seed of the same population are also able to germinate (Clevering 1995) and grow terrestrially, as has been shown in the present study, without showing differ ences in RGR with S.l. tabernaemontani.…”

“…Stratified seeds, obtained from the same sources as described in Clevering (1995) were germinated in an incubator with a light/dark regime of 12 h at 3 0°C and 12 h at 10°C in 2-cm deep water (submerged treatment) or in waterlogged (terrestrial treatment) sandy substrate. One week after germination, the submerged seedlings were planted in pots of 150 ml and the terrestrial ones in pots of 500 ml.…”

Summary1. Adults of the emergent macrophytes Scirpus lacustris ssp. lacustris {S.l. lacustris), S. lacustris ssp. tabernaem ontani (S.L tabernaem ontani) and S. maritimus occur along a gradient in water depth from deep to shallow water. This study examined whether seedlings of these taxa respond differently to changing hydrological conditions. 2. Seedlings of both S. lacustris subspecies showed the highest relative growth rate (RGR) under terrestrial growth conditions, whereas S. maritimus did so under submerged growth conditions. In all three taxa, shading reduced the mean RGR of terrestrial seedlings more strongly than that of submerged ones. 5. Growth of all three taxa was reduced considerably after seedlings were transferred from terrestrial to submerged growth conditions. This effect was stronger with increas ing age of seedlings. W hen transferred the other way round, seedlings of S.l. tabernae montani and S. m aritimus adapted quickly to the terrestrial growth conditions, whereas the thin leaves of S.L lacustris partly dried out. 6. It was concluded that although seedling establishment of all three Scirpus taxa will be most successful under terrestrial conditions, subsequent fluctuating water levels may act as a strong selective force. This may determine the distribution of Scirpus taxa along a gradient in water depth during seedling establishment.

“…From each population, the inflorescences of 60 shoots were collected at random, with each shoot separated from each other by at least 10 m. In the laboratory, the seeds were separated from the spikes and those coming from distinct populations were mixed to a homogeneous sample representative of the study area. The seeds were stored in darkness at 4 ∞C in order to stimulate germination (Clevering 1995).…”

Helophyte germination in a Mediterranean salt marsh: Gut-passage by ducks changes seed response to salinity

et al. 2004

Abstract.Questions: In seeds which are regularly consumed by waterbirds in the field, how does gut-passage modify their response to salinity gradients? Locations: Doñana National Park salt marsh, south-west of Spain. Methods: Seeds of Scirpus litoralis and Scirpus maritimus were collected and force fed to mallards (Anas platyrhynchos). Both the ingested seeds (passage) and non-ingested seeds (controls) were exposed, in germination chambers, to a salinity range similar to that observed in the field (0-32 dS/m). After 30 days, the total percentage germination, the duration of the dormancy period and the germination speed were computed. The response of the different germination parameters to ingestion and salinity was analyzed using generalized lineal models. Recovery tests on seeds that did not germinate in the various treatments and tests of the effect of ingestion on the intrinsic variability in seed response were also performed. Results: An increase in salinity reduced germinability and increased the length of dormancy, while gut passage increased the intrinsic variability of the temporal seed response in both species. In S. litoralis there was a significant interaction between the effects of salinity and passage on germination rate. Passage increased germination rate at low salinities (£2 dS/m) but decreased it at high salinities (≥4 dS/m). Conclusion: Gut-passage by ducks significantly changes seed response to salinity. The outcome of plant-animal interactions can be influenced by environmental gradients. Studies of germination in response to gut passage that do not take such gradients into account may produce misleading results.
