Ethnic segregation in nations straddling the world’s highest terrains may be reinforced by the biological tolerance different peoples have to altitude, according to one of the first studies to examine the effect of elevation on ethnic demographics.

Research from Princeton University published in the journal Applied Geography suggests that people native to low-lying areas can be naturally barred from regions such as the Tibetan Plateau, the Andes or the Himalayas by altitude sickness, which is caused by low oxygen concentration in the air and can be life-threatening. As a result, the homogeny of the local population can increase with elevation. In nations shared by people of high- and lowland extractions, this separation can potentially increase ethnic tension.

GAINESVILLE, Fla. — Paving a highway across South America is providing lessons on the impact of road construction elsewhere.

That’s what a University of Florida researcher and his international colleagues have determined from analyzing communities along the Amazonian portion of the nearly 4,200-mile Interoceanic Highway, a coast-to-coast road that starts at ports in Brazil and will eventually connect to ones in Peru.

ARAMARK executive, industry experts share entrepreneurial lessons with students

Believe in the power of possibility. “Possibility for success, possibility to impact others, possibility to create jobs and contribute to your communities – the possibility of successful business ownership is real for you,” Christina Estrada told students in a keynote address at the sixth annual Hospitality and Entrepreneurship Summit held recently on the University of Delaware campus in Newark.

For Estrada, global chief diversity officer for ARAMARK, possibility is rooted in an entrepreneurial spirit that sparks creative thinking into diversification.

“As an aspiring entrepreneur you need creative thinking after the big idea,” said Estrada. “You need to understand your industry and know what your customers need that is unique, as well as what they want consistently and that is reliable. As an aspiring entrepreneur, you need to believe in the power of possibility.” (more…)

To Turn Up The Heat in Chilies, Just Add Water

Biologists have learned in recent years that wild chilies develop their trademark pungency, or heat, as a defense against a fungus that could destroy their seeds. But that doesn’t explain why some chilies are hot and others are not.

New research provides an answer: Hot chilies growing in dry areas need more water to produce as many seeds as non-pungent plants, but the Fusarium fungus is less of a threat in dryer environments so chilies in those areas are less likely to turn up the heat. In wetter regions, where Fusarium thrives, wild chilies build up their reserves of spicy capsaicin in self-defense. (more…)

*Historical ecology of the Andes indicates desert-like setting on the horizon*

Catastrophic drought is on the near-term horizon for the capital city of Bolivia, according to new research into the historical ecology of the Andes.

If temperatures rise more than 1.5 to 2 degrees Celsius (3 to 5 degrees Fahrenheit) above those of modern times, parts of Peru and Bolivia will become a desert-like setting.
