Taxonomic Composition, Paleoecology and Biostratigraphy of Late Cretaceous Diatoms from Devon Island, Nunavut, Canadian High Arctic

Diatoms are the most diverse group of algae, playing a major role in global carbon and silicon cycles (Kidder and Erwin, 2001; Armbrust, 2009) and inhabiting virtually any environment that provides moisture and sunlight (Mann, 1999). Thus, they offer important information to help reconstruct paleoen-vironments and clarify stratigraphic relationships. Their strati-graphic range extends down at l...

Creating a Little Big Bang on Long Island

Niger: too little, too late.

Niger—with the world’s fastest growing population, its highest total fertility rate (TFR), a small and diminishing amount of arable land, low annual rainfall, a high level of malnutrition, extremely low levels of education, gross gender inequities and an uncertain future in the face of climate change—is the most extreme example of a catastrophe that is likely to overtake the Sahel. The policies...
