    In situ conservation of CWR in Spain: present and future

    Crop Wild Relative,(10) 24-26.

    One of the tasks carried out under the frame of the PGR Secure project was the development of national strategies for the preservation of CWR across Europe. These national strategies have produced lists of prioritized CWR, inventories and also studied the in situ and ex situ conservation status of the CWR selected, as well as generated proposals for better conservation and better access to them (Fitzgerald, 2013; Rubio Teso et al., 2013; Panella et al., 2014).

    Factors Affecting Seed Germination and Seedling Emergence of Asia Minor Bluegrass ( Polypogon fugax )

    Weed Science 63(2) 440-447.

    Abstract Little published information is available related to seed germination and seedling establishment of Asia Minor bluegrass, a problematic grass weed in some regions of China. The objective of this study was to examine the effects of different environmental factors on Asia Minor bluegrass seed germination. The optimum temperature for germination was around 10 to 20 C, and more than 90% of seeds germinated under 20/10 and 25/15 C temperature regimes. Also, light and pH did not appear to have any effect on seed germination. Asia Minor bluegrass was sensitive to osmotic stress, but...

    Taxonomy in the electronic age and an e-monograph of the papaya family (Caricaceae) as an example

    Cladistics Forthcoming.

    The need for taxonomists to take full advantage of biodiversity informatics has been clear for at least 10 years. Significant progress has been made in providing access to taxonomic resources online, including images of specimens (especially types), ori- ginal species descriptions, and georeferenced collection data. However, in spite of persuasive calls for e-monography, there are few, if any, completed project, even though monographic research is the only mechanism for reducing synonymous names, which are estimated to comprise 50% of all published names. Caricaceae is an economically...

    Endemic wild potato (Solanum spp.) biodiversity status in Bolivia: Reasons for conservation concerns

    Journal for Nature Conservation 22(2) 113-131.

    Crop wild relatives possess important traits, therefore ex situ and in situ conservation efforts are essential to maintain sufficient options for crop improvement. Bolivia is a centre of wild relative diversity for several crops, among them potato, which is an important staple worldwide and the principal food crop in this country. Despite their relevance for plant breeding, limited knowledge exists about their in situ conservation status. We used Geographic Information Systems (GIS) and distribution modelling with the software Maxent to better understand geographic patterns of endemic wild...

    Hotspots and gaps in the world collection of subterranean clover (Trifolium subterraneum L.)

    The Journal of Agricultural Science Forthcoming.

    Subterranean clover (Trifolium subterraneum L.) is the most important annual pasture legume in the winter-dominant rainfall areas of Southern Australia. Systematic germplasm collections of subterranean clover from its centre of origin have been made since the 1950s, particularly by Australian scientists, in order to broaden the genetic base of the species. The present study reports on a meta-analysis of the distribution of the world collection of subterranean clovers and their relationships to eco-geographic variables of the collection sites in their native habitat. Diversity hotspots (areas...

    Predicting potential global distributions of two miscanthus grasses: implications for horticulture, biofuel production, and biological invasions

    PloS one 9(6) e100032.

    In many regions, large proportions of the naturalized and invasive non-native floras were originally introduced deliberately by humans. Pest risk assessments are now used in many jurisdictions to regulate the importation of species and usually include an estimation of the potential distribution in the import area. Two species of Asian grass (Miscanthus sacchariflorus and M. sinensis) that were originally introduced to North America as ornamental plants have since escaped cultivation. These species and their hybrid offspring are now receiving attention for large-scale production as biofuel...

    Bioclimatic evaluation of geographical range in Fragaria (Rosaceae): consequences of variation in breeding system, ploidy and species age

    Botanical Journal of the Linnean Society 176(1) 99-114.

    The evaluation of the intrinsic and extrinsic forces that determine geographical range sizes and niche breadth is key to the understanding of species distributions and for informing the conservation of biodiversity. Fragaria (Rosaceae) contains the economically important cultivated strawberry (Fragaria × ananassa subsp. ananassa) and numerous wild species. Using georeferenced species records and global bioclimatic data, we describe the bioclimatic niches for 21 Fragaria spp. and investigate the relationship between their niches and geographical range size, breeding system, ploidy and time...

    Multiple lines of evidence for the origin of domesticated chili pepper, Capsicum annuum, in Mexico

    Proceedings of the National Academy of Sciences of the United States of America 1-6.

    The study of crop origins has traditionally involved identifying geographic areas of high morphological diversity, sampling populations of wild progenitor species, and the archaeological retrieval of macroremains. Recent investigations have added identification of plant microremains (phytoliths, pollen, and starch grains), biochemical and molecular genetic approaches, and dating through (14)C accelerator mass spectrometry. We investigate the origin of domesticated chili pepper, Capsicum annuum, by combining two approaches, species distribution modeling and paleobiolinguistics, with...

    Balancing bioenergy and biosecurity policies: estimating current and future climate suitability patterns for a bioenergy crop

    GCB Bioenergy 6(5) 587-598.

    In an apparent paradox, bioenergy crops offer potential benefits to a world adjusting to the challenges of climate change and declining fossil fuel stocks, as well as potential ecological and economic threats resulting from biological invasions. In considering this paradox it is important to understand that benefits and threats may not always be apparent in equal measure throughout the potential range of each candidate biofuel species. In some environments, a species could potentially produce valuable biological materials without posing a significant invasion threat. In this study, we develop...

    Quantifying and mapping ecosystem services: Demand and supply of pollination in the European Union

    Ecological Indicators 36 131-141.

    Biotic pollination is an important ecosystem service for the production of many food crops. The supply of pollination is mostly studied at the landscape scale while recent studies on the demand for pollination services provide a global-scale picture based on aggregate national-level data. This paper quantifies both demand and supply of pollination in the European Union (EU) at a relatively high spatial resolution, allowing an analysis of the match between demand and supply. Finally, we evaluate how policies interact with the spatial differences between demand and supply of this ecosystem...
