In case you do not receive our weekly announcements, I'm sending this note about a talk today at 12 in the Herbarium. If you would like to attend in person, we're in Herring Hall — the small old building between Forbes and Marley. The talk will also be live-streamed;
see the link below. </div>

<span style="font-family: Aptos, sans-serif; font-size: 11pt; color: rgb(33, 33, 33);">Ultramafic landscapes are highly selective, characterised by low calcium-to-magnesium ratios, nutrient limitation, and elevated nickel, cobalt, and chromium. These conditions
drive strong edaphic endemism, with many species restricted to small, fragmented outcrops. First identified in the 1950s in Italy in a mustard family species, metal hyperaccumulation, especially of nickel, has evolved multiple times in these systems. After
decades of limited attention, research accelerated in the 1980s as technological advances enabled major breakthroughs in physiology. Studies from Malaysia, New Caledonia, the Philippines, Maryland, California, and elsewhere have since clarified many previously
unknown aspects of this biological anomaly. Meanwhile, as scientists worldwide explored ultramafic ecosystems, Rufus Chaney (USDA), working with collaborators, pioneered the practical application of this biology in the United States, first through phytoremediation
and later phytomining and agromining, using hyperaccumulators for environmental cleanup and metal recovery.</span></p>
