The shape of a seed bank tree

open access: yesJournal of Applied Probability, 2022
AbstractWe derive the asymptotic behavior of the total, active, and inactive branch lengths of the seed bank coalescent when the initial sample size grows to infinity. These random variables have important applications for populations evolving under some seed bank effects, such as plants and bacteria, and for some cases of structured populations like ...

Seed bank persistence of artificial vegetation under stochastic shock in desert regions

open access: yesEcological Indicators, 2021
Seed bank persistence plays a significant role in maintaining the sustainability of artificial vegetation in desert regions. However, the periods of droughts after each rainfall event form a series of stochastic shocks and result in depletion of the seed

Soil Seed Bank and above-ground vegetation at Chitgar Forest Park of Tehran [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2016
After over five decades of establishing plantations in Chitgar Forest Park in Tehran, no study has yet been carried out on the soil seed bank in this region.

A global synthesis of fire effects on soil seed banks

open access: yesGlobal Ecology and Conservation, 2022
Fire is a major disturbance affecting plant communities in terrestrial ecosystems. Understanding fire effects on soil seed banks is critical in the context of altered global fire regimes. Through a systematic and quantitative review of the literature, we

New records of alien Euphorbia hypericifolia L. (Euphorbiaceae) from the United Arab Emirates [PDF]

open access: yesCheck List
Euphorbia hypericifolia L. (Euphorbiaceae) is reported here as a new record for the vascular flora of the United Arab Emirates. This species is native to the tropics and subtropics of the New World and was recorded from a mountain wadi bank (gravel or ...

Response of Composition, Diversity and Functional Groups of Soil Seed Bank under Corrective Practices of Floodwater Spreading in the Kowsar Aquifer Management Station, The Province of Fars [PDF]

open access: yesپژوهش‌های آبخیزداری, 2021
Floodwater spreading plays an important role in restoring and enhancing the vegetative cover, improving soil fertility, groundwater recharge and desertification control. These have been achieved in some of the arid and semi-arid regions of Iran.

SEEDS AND SEED BANKS [PDF]

open access: yesNew Phytologist, 1987
SummaryThe involvement of four factors (life history, predation, possession of a persistent seed bank and seedling establishment) in the evolution of seed size in flowering plants is discussed. Among herbacaeous plants, biennials seem to have larger seeds than annuals and perennials, a difference which may explain the capacity of some biennials to ...

Simulated Photovoltaic Solar Panels Alter the Seed Bank Survival of Two Desert Annual Plant Species

open access: yesPlants, 2020
Seed bank survival underpins plant population persistence but studies on seed bank trait-environment interactions are few. Changes in environmental conditions relevant to seed banks occur in desert ecosystems owing to solar energy development.

Microscale Insight into Microbial Seed Banks [PDF]

open access: yesFrontiers in Microbiology, 2016
Dormancy is a general microbial life-history trait that leads to the emergence of seed banks across diverse ecosystems. While the primary forces driving seed banks include macroscale factors like resource supply, the importance of microscale factors such as individual encounters with resource molecules are often overlooked.

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

open access: yesPlant 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 ...
