    Ex situ conservation priorities for the wild relatives of potato (solanum L. Section petota).

    PloS one 10(4) e0122599.

    Crop wild relatives have a long history of use in potato breeding, particularly for pest and disease resistance, and are expected to be increasingly used in the search for tolerance to biotic and abiotic stresses. Their current and future use in crop improvement depends on their availability in ex situ germplasm collections. As these plants are impacted in the wild by habitat destruction and climate change, actions to ensure their conservation ex situ become ever more urgent. We analyzed the state of ex situ conservation of 73 of the closest wild relatives of potato (Solanum section Petota)...

    Distributions, ex situ conservation priorities, and genetic resource potential of crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas].

    Frontiers in plant science 6 251.

    Crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas] have the potential to contribute to breeding objectives for this important root crop. Uncertainty in regard to species boundaries and their phylogenetic relationships, the limited availability of germplasm with which to perform crosses, and the difficulty of introgression of genes from wild species has constrained their utilization. Here, we compile geographic occurrence data on relevant sweetpotato wild relatives and produce potential distribution models for the species. We then assess the comprehensiveness of...

    Downscaling Pest Risk Analyses: Identifying Current and Future Potentially Suitable Habitats for Parthenium hysterophorus with Particular Reference to Europe and North Africa

    PLOS ONE 10(9) e0132807.

    Pest Risk Assessments (PRAs) routinely employ climatic niche models to identify endangered areas. Typically, these models consider only climatic factors, ignoring the ‘Swiss Cheese’ nature of species ranges due to the interplay of climatic and habitat factors. As part of a PRA conducted for the European and Mediterranean Plant Protection Organization, we developed a climatic niche model for Parthenium hysterophorus, explicitly including the effects of irrigation where it was known to be practiced. We then downscaled the climatic risk model using two different methods to identify the suitable...

    The Domestication of Annatto (Bixa orellana) from Bixa urucurana in Amazonia

    Economic Botany 69(2) 127-135.

    Annatto (Bixa orellana) is an important colorant domesticated in the Neotropics, although it is not clear where or from which wild populations. We reviewed the available biological, archaeological, and ethnographic information about annatto, and integrated this with our recent ethnobotanical observations of cultivated and non–cultivated populations in order to evaluate the hypothesis that what is classified as Bixa urucurana is the wild ancestor of cultivated annatto, Bixa orellana. Most B. urucurana populations we found in Amazonia occurred in open forests or anthropogenic landscapes,...

    Future climate effects on suitability for growth of oil palms in Malaysia and Indonesia

    Scientific Reports 5 14457.

    The production of palm oil (PO) is highly profitable. The economies of the principal producers, Malaysia and Indonesia, and others, benefit considerably. Climate change (CC) will most likely have an impact on the distribution of oil palms (OP) (Elaeis guineensis). Here we present modelled CC projections with respect to the suitability of growing OP, in Malaysia and Indonesia. A process-oriented niche model of OP was developed using CLIMEX to estimate its potential distribution under current and future climate scenarios. Two Global Climate Models (GCMs), CSIRO-Mk3.0 and MIROC-H, were used to...

    Risk evaluation of pesticide use to protected European reptile species

    Biological Conservation 191 667-673.

    Environmental contamination is supposed to be a reason for population declines in reptiles. Especially intensification and expansion of agriculture are leading to increased pesticide exposure risks for wildlife. In the European Union, Special Areas of Conservation (SACs) have been established for the conservation of taxa listed in Annex II of the Habitats Directive. In the SACs, agricultural land use is legal. Therefore, we conducted a risk evaluation of pesticide exposure for Annex II reptiles by calculating proportions of land use with regular pesticide applications within SACs. Using three...

    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...
