Predicting the potential threat of Casuarina equisetifolia to three endemic plant species on the Turks and Caicos Islands.
Invasive species are one of the main threats to the loss of global biodiversity. Controlling such species requires a high input of effort and resources and therefore it is important to focus control on areas that will maximize gains for conservation. We present a spatial modelling approach that will help... -

Early Events in Monocot Evolution.
Tracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree. It explores a series of broad but linked themes, providing for the first time a detailed and coherent view...Royal Botanic Gardens, Kew

(Epi)genetic control of secondary seed dormancy depth and germination in Capsella bursa-pastoris.
Despite the importance of secondary dormancy for plant life cycle timing and survival, there is insufficient knowledge about the (epigenetic) regulation of this trait at the molecular level. Our aim was to determine the role of (epi)genetic processes in the regulation of secondary seed dormancy using natural genotypes of the... -

Stimulatory and inhibitory effects of light on Cereus repandus (Cactaceae) seed germination are strongly dependent on spectral quality.
In small seeds, light often promotes germination and longer-term exposure to darkness reduces light sensitivity. In cacti inhabiting harsh environments, a rapid response to light exposure is potentially advantageous for seedling establishment. We exposed dark-imbibed seeds of the cactus to doses of red (RED) light and far-red (FR) light. The...Yang, X-Y. ; Pritchard, Hugh W.

Cryptic Species : morphological stasis, circumscription, and hidden diversity.
Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role...Cambridge University Press

Assessing non-detrimental trade for a CITES Appendix II-listed plant species: the status of wild and cultivated Galanthus woronowii in Georgia.
A process for the review of significant trade in species listed in CITES Appendix II was established to address problems with the application of CITES Article IV. Article IV states that international trade in Appendix II species requires a Scientific Authority of the state of export to determine that such... -

Hyparrhenia variabilis and Hyparrhenia cymbaria (Poaceae): New for the Americas, Successful in Mexico.
(boat thatching grass, ipopo grass) and (no common name), robust African savanna grasses with complex taxonomies, have not yet been reported for the Americas. Large populations were found in central Jalisco, northeastern Michoacán, and Morelos, Mexico. The species grow in maize and sorghum fields as well as on roadsides and... -

Molecular phylogeny resolves a taxonomic misunderstanding and places Geisleria close to Absconditella s. str. (Ostropales : Stictidaceae).
The phylogenetic position of the genus and its type species was reconstructed using sequence data of the mitochondrial small subunit (mtSSU), the nuclear large subunit rDNA (nuLSU) and the first subunit of the RNA polymerase ( ). The species, previously classified in (Eurotiomycetes) and (Dothideomycetes), is sister to the type...Aptroot, André ; Parnmen, Sittiporn ; Lücking, Robert ; Baloch, Elisabeth ; Jungbluth, Patricia …

Pericarp structure of Glebionis coronaria (L.) Cass. ex Spach (Asteraceae) cypselae controls water uptake during germination.
(L.) Cass. ex Spach is a common Mediterranean weed producing distinctive central and peripheral dormant cypselae with a hard fruit coat, which was previously hypothesized to impose physical dormancy. Analysis of water uptake in cypselae and in naked seeds showed that it preferentially takes place at the basal end of...Garland chrysanthemum, Heterocarpy, Imbibition, Pericarp constraint, Glebionis coronaria, Germination, and Dormancy

Seed heteromorphy influences seed longevity in Aegilops.
The genus belongs to the secondary gene pool of wheat and has great importance for wheat cultivar improvement. As a genus with only annual species, regeneration from seeds in is crucial. In several species in , spikes produce different seed morphs, both in size and germination patterns. However, little is...Phenology, Seed conservation, Crop wild relatives, Seed dimorphism, Controlled ageing test, Germination ecology, and Soil seed bank

Contribution of seed banks across Europe towards the 2020 Global Strategy for Plant Conservation targets, assessed through the ENSCONET database.
To meet the international biodiversity targets of the 2011–2020 Global Strategy for Plant Conservation, it is important to assess the success of coordinated ex situ plant conservation initiatives such as the European Native Seed Conservation Network (ENSCONET), which operated during 2005–2009, and the ENSCONET Consortium, which was established in 2010....Medicinal plants, ENSCONET, Crop wild relatives, European Red List of Vascular Plants, Ex situ, Global Strategy for Plant Conservation, and Seed conservation

The Role of Prosopis in Ecological and Landscape Change in the Samaca Basin, Lower Ica Valley, South Coast Peru from the Early Horizon to the Late Intermediate Period.
The lower Ica Valley on the hyperarid south coast of Peru is today largely depopulated and bereft of cultivation, yet its extensive archaeological remains attest to substantial prehispanic populations. This paper describes archaeological investigations to retrace changes in geomorphology, ecology, and land-use in Samaca, one of the riparian oasis basins...Early Intermediate Period, Archaeology, Ecological change, Prosopis pallida, Samaca Basin (Peru), Lower Ica Valley (Peru), Prehispanic populations, Landscape change, South Coast Peru, and Peru

A new Psammina species with exceptionally long conidial arms, with a key to the ten known species of the genus
The algicolous and lichenicolous species Psammina filamentosa is described from the Netherlands and the UK, and is characterized by long (generally over 50 μm) and somewhat tapered conidial arms. Psammina filamentosa is compared with other Psammina specimens found in the same habitat, growing on algae or lichens on the dry...van der Kolk, Henk-Jan ; Earland-Bennett, Peter M. ; Hawksworth, David L.

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 …

Dry architecture: towards the understanding of the variation of longevity in desiccation-tolerant germplasm
Desiccation-tolerant (DT) plant germplasm (i.e. seeds, pollen and spores) survive drying to low moisture contents, when cytoplasm solidifies, forming a glass, and chemical reactions are slowed. DT germplasm may survive for long periods in this state, though inter-specific and intra-specific variation occurs and is not currently explained. Such variability has...Ballesteros, Daniel ; Pritchard, Hugh W. ; Walters, Christina
