Abstract:

The primary problems which plants growing on serpentine soil must overcome are high magnesium concentrations and calcium deficiency. The ability of Allium cratericola to successfully exploit both serpentine and non-serpentine habitats may be due to physiological adaptations which compensate for unusual mineral composition of the soil. Although the Table Mountain soil is described as non serpentine, it bears ionic similarities to the three serpentine soils studied in this investigation. With the advent of modern biochemical techniques in plant physiology, there are ample opportunities to expand

Abstract:

Ultramafic soils enriched in nickel, such as found in Australia and New Caledonia, are associated with unique, diverse and poorly known vegetation communities. Re-establishment of these highly specific ecosystems is still a challenge for Ni mining companies. Ultramafic vegetation communities are the outcome of a long evolution process resulting in their adaptation to the extreme soil conditions found on ultramafic outcrops. Mycorrhizal fungi, a very common plant symbiont, are generally thought to be beneficial to plants in other ecosystems, providing plants with phosphorus and even promoting m

Abstract:

Reproductive barriers are vital to generating new species as well as maintaining distinct species. Investigating reproductive barriers between closely related plant taxa helps us to understand how these barriers are maintained, particularly between rare and widespread relatives. Layia jonesii, a rare San Luis Obispo County serpentine endemic, and L. platyglossa, a common coastal species, co-occur on serpentine derived hillsides and are interfertile. At these locations, L. jonesii is isolated to dry soils near serpentine rock outcrops and L. platyglossa is located on slightly deeper grassland s
