Exploring seed longevity of UK native trees: implications for ex situ conservation
UK trees require increased conservation efforts due to sparse and fragmented populations. Ex situ conservation, including seed banking, can be used to better manage these issues. We conducted accelerated ageing tests on seeds of 22 UK native woody species, in order to assess their likely longevity and optimize their conservation...Davies, Rachael M. ; Hudson, Alice R. ; Dickie, John B. ; Cook, Charlotte ; O'Hara, Tom …

Trade‐off between seed dispersal in space and time.
Seed movement and delayed germination have long been thought to represent alternative risk‐spreading strategies, but current evidence covers limited scales and yields mixed results. Here we present the first global‐scale test of a negative correlation between dispersal and dormancy. The result demonstrates a strong and consistent pattern that species with...Chen, Si‐Chong ; Poschlod, Peter ; Antonelli, Alexandre ; Liu, Udayangani ; Dickie, John B.

Conserving orthodox seeds of globally threatened plants ex situ in the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK: the status of seed collections
We reviewed the status of orthodox seed collections of globally threatened plants conserved in − 20 °C long-term storage at the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK in terms of their geographic and bioclimatic representativeness, taxonomic and genetic diversity, quality and physiological status. The comprehensive dataset used spans... -

Macroevolutionary patterns in seed component mass and different evolutionary trajectories across seed desiccation responses.
Seed coat and seed reserve show substantial mass variation, play different roles in plant life strategies and are shaped by different selective forces. However, remarkably little is known about the macroevolution of the relative allocation in seed components and its influence on important ecophysiological processes. Using phylogenetic comparative methods and...Chen, Si‐Chong ; Wu, La‐Mei ; Wang, Bo ; Dickie, John B.
