Evaluating germinability of eight desert halophytes under long-term seed storage: Implications for conservation

Plant Diversity, 2019
Ex situ conservation in seed banks is a potential complementary conservation strategy for native plant species. It is well established that ex situ seed banking of native wild plants prolongs seed viability and thereby preserves genetic and species ...

Vegetation Re-development After Fen Meadow Restoration by Topsoil Removal and Hay Transfer [PDF]

, 2009
We investigated the effects of different restoration treatments on the development of fen meadow communities: (1) depth of topsoil removal, with shallow (circa 20 cm) and deep (circa 40 cm) soil removal applied, (2) transfer of seed-containing hay, and ...

Large old trees need more conservation attention: A case of Tamarix aphylla in the arid deserts of the United Arab Emirates

Journal of Asia-Pacific Biodiversity, 2015
Large old trees are often recognized for the provision of variety of ecosystem services to humanity. This paper reports the existence of a large old Tamarix aphylla (L.) Karst. tree in the Hamriyah area of Sharjah, the United Arab Emirates.

The effect of successional stage and salinity on the vertical distribution of seeds in salt-marsh soils [PDF]

, 2009
Seed bank density and similarity between seed bank and above-ground vegetation along depth were compared between two salt-marshes different in age. In addition, the effect of salinity on the variation in seed bank density and similarity between seed bank

Similarity between seed bank and herb layer in a natural deciduous temperate lowland forest

Acta Societatis Botanicorum Poloniae, 2011
Forest seed banks mostly studied in managed forests proved to be small, species poor and not reflecting aboveground species composition. Yet studies conducted in undisturbed communities indicate a different seed bank characteristic. Therefore we aimed at

Banana seed genetic resources for food security: Status, constraints, and future priorities

Food and Energy Security, 2022
Storing seed collections of crop wild relatives, wild plant taxa genetically related to crops, is an essential component in global food security. Seed banking protects genetic resources from degradation and extinction and provides material for use by ...

The Relationship between the Soil Seed Bank and Above-Ground Vegetation of a Coastal Barrier Island [PDF]

, 1995
The germinable soil seed bank is described from a coastal barrier island off the northwest coast of Florida, USA. Soil samples collected from seven vegetation types, recently deposited dredge spoil and unvegetated areas in autumn 1990 and spring 1991 ...

The Relative Contributions of Seed Bank, Seed Rain, and Understory Vegetation Dynamics to the Reorganization of Tsuga Canadensis Forests After Loss due to Logging or Simulated Attack by Adelges tsugae [PDF]

, 2013
Profound changes are occurring in forests as native insects, nonnative insects, or pathogens irrupt on foundation tree species; comprehensive models of vegetation responses are needed to predict future forest composition.

Organic Cropping Systems do not Increase Weed Seed Numbers but do Increase Weed Diversity [PDF]

, 2020
The influence of different cropping systems on the soil weed seed bank after the first crop rotation within a five-field crop rotation (barley undersown with red clover, red clover, winter wheat, pea, potato) in three organic (Org) and in two ...

Seed rain and seed bank of a draw-down zone and their similarities to vegetation under the regulated water-level fluctuation in Xiangxi River

Journal of Freshwater Ecology, 2020
Construction of the Three Gorges Reservoir converted areas of the original terrestrial ecosystem along the shores into a draw-down zone with a fluctuating water-level at an elevation ranging between 145 and 175 m. The water-level fluctuation is regulated
