Conserving wild bees for crop pollination
A substantial proportion of the worlds crops rely on insect pollination, yet for many we have little or no information as to which pollinators are most effective. Pollinator management has traditionally focussed exclusively on one species, the honeybee, Apis mellifera. Yet this bee is not able to adequately pollinate some crops, and is an unreliable pollinator in cold and wet climates. Natural ...
متن کاملEnhancing 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 کاملPotential Implications of Climate Change on Aegilops Species Distribution: Sympatry of These Crop Wild Relatives with the Major European Crop Triticum aestivum and Conservation Issues
Gene flow from crop to wild relatives is a common phenomenon which can lead to reduced adaptation of the wild relatives to natural ecosystems and/or increased adaptation to agrosystems (weediness). With global warming, wild relative distributions will likely change, thus modifying the width and/or location of co-occurrence zones where crop-wild hybridization events could occur (sympatry). This ...
متن کاملTransgene introgression in crop relatives: molecular evidence and mitigation strategies.
Incorporation of crop genes into wild and weedy relative populations (i.e. introgression) has long been of interest to ecologists and weed scientists. Potential negative outcomes that result from crop transgene introgression (e.g. extinction of native wild relative populations; invasive spread by wild or weedy hosts) have not been documented, and few examples of transgene introgression exist. H...
متن کاملA case for conserving common species
I grew up in a country where fish were, first and foremost, food. At the age of nine or so, I started following my dad and uncle to nearby rivers to fish on weekends, and soon I learned to make my own tackle and go back to the rivers to fish with my friends. We never caught a lot of fish, but every fish we caught came home with us to be eaten. It never occurred to us to consider what ecological...
