Abstract:
Understanding how local adaptation arises within species is essential when making predictions about how populations may respond to environmental change. Serpentine soils present an ideal system to study the processes leading to local adaptation in plant populations. Theses soils have a scattered distribution, are deficient in several nutrient minerals, have high heavy metal content, and a poor water holding capacity; all factors contributing to a strong selective pressure against plant growth.

Abstract:
Plant morphology and function are sensitive to rising atmospheric carbon dioxide (CO2) concentrations, but evidence that CO2 concentration can act as a selective pressure driving evolution is sparse. Plants originating from naturally high CO2 springs are subjected to elevated CO2 concentration over multiple generations, providing an opportunity to predict how adaptation to future atmospheres may occur, with important implications for future plant conservation and crop breeding strategies. Using Plantago lanceolata L. from such a site (the ‘spring’ site) and from an adjacent ambient CO2 site (‘

Abstract:
The obligately outbreeding root hemiparasite Striga hermonthica (Orobanchaceae)is a serious threat to subsistence agriculture in sub-Saharan Africa. Resistance to this parasite in its crop hosts, such as rice, sorghum and maize, is not common, and the evolution of host adaptations that are able to overcome new sources of resistance is an ever-present risk. Research into host adaptation in S. hermonthica has generally sought to correlate the genetic relationship between Striga individuals with host identity; however, such approaches must be supported by lab-based evidence of host adaptation, ot
