Enhancing the Conservation of Crop Wild Relatives in England
Humans require resilient, rapidly renewable and sustainable supplies of food and many other plant-derived supplies. However, the combined effects of climate change and population growth compromise the provision of these supplies particularly in respect to global food security. Crop wild relatives (CWR) contain higher genetic diversity than crops and harbour traits that can improve crop resilien...
متن کاملBack into the wild—Apply untapped genetic diversity of wild relatives for crop improvement
Deleterious effects of climate change and human activities, as well as diverse environmental stresses, present critical challenges to food production and the maintenance of natural diversity. These challenges may be met by the development of novel crop varieties with increased biotic or abiotic resistance that enables them to thrive in marginal lands. However, considering the diverse interactio...

متن کاملVicarious Learning: more than common ground
The Vicarious Learner project is investigating the roleof dialogue in learning and, more specifically, how learners benefit fromopportunities to ’overhear’ other learners. A direct challenge to thisconcept comes from a study by Schober and Clark which claims that only direct participants can learneffectively from dialogue. We dispute this claim both on grounds thattheir own data indicate otherw...
متن کاملEcogeography and utility to plant breeding of the crop wild relatives of sunflower (Helianthus annuus L.)
Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding. Geographic occurrence, bioclimatic, and biophysical data were used to predict species distributions, range overlap and niche occupancy in 36 taxa closely related to sunflower (Helianthus annuus L.). Taxa lacking com...
