The environmental behavior of iron, as well as its uptake by plants, its absorption by human and animals and its storage and transport all depend on its oxidation state, making redox speciation ...

While Madagascar is famous for its incredible diversity of plants and animals, a new study suggests that the island’s rate of speciation has slowed to a crawl. The research, published last week in the ...
