Recruitment limitation of forest communities in a degraded Mediterranean landscape

Question: How does habitat degradation affect recruitment limitation and its components (seed limitation versus establishment limitation) of woody plant communities in a Mediterranean landscape? Location: 1600-1900m a.s.l. in the Sierra Nevada National Park, southern Spain. The landscape is a mosaic composed of native forest and two degraded landscape units: reforestation stands and shrubland. ...

Seed size, seedling morphology, and response to deep shade and damage in neotropical rain forest trees.

To investigate the existence of coordinated sets of seedling traits adapted to contrasting establishment conditions, we examined evolutionary convergence in seedling traits for 299 French Guianan woody plant species and the stress response in a shadehouse of species representing seed size gradients within five major cotyledon morphology types. The French Guianan woody plant community has larger...

Cryopreservation of Smirnovia iranica (Sabeti) Seeds and Evaluation of Cryopreserved Seeds under Laboratory, Greenhouse and Natural Habitat Conditions

Smirnovia iranica (Sabeti) synonym: Smirnovia turkestana (Bunge) is a deciduous perennial bushy species of the Fabaceae (Papilionaceae) family. The species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. They have an important role in natural vegetation of desert and sand dune stabilization. Limited growing areas, grazing due to good pa...

Seed limitation and the coexistence of pioneer tree species

Seed limitation, defined as the failure of seeds to arrive at sites favorable for recruitment, may be a critical force structuring plant communities. When seed limitation is strong, interspecific competition is reduced, and competitive exclusion may be slowed to the extent that diversity can be maintained through speciation and migration. In mature tropical forests, seed limitation may be espec...

Effects of forest fragmentation on seed dispersal and seedling establishment in ornithochorous trees.

Habitat fragmentation increases seed dispersal limitation across the landscape and may also affect subsequent demographic stages such as seedling establishment. Thus, the development of adequate plans for forest restoration requires an understanding of mechanisms by which fragmentation hampers seed delivery to deforested areas and knowledge of how fragmentation affects the relationship between ...
