Marcus Garvey Movement Owes Large Debt to Caribbean Expats, UCLA Historian Finds

Conventional wisdom has long held that Marcus Garvey’s Universal Negro Improvement Association, which advocated racial self-help and the unity of the African diaspora, grew out of the heady political and cultural environment of the Harlem Renaissance and benefited African Americans above all other black people. Any Caribbean role, according to this view, was separate and incidental to the primary legacy bequeathed to American race relations by the charismatic Jamaica native.

Now a UCLA historian argues the reverse in the first book of a multi-volume series on the Garvey movement and the Caribbean. From the UNIA’s organizational structure to its most valuable foot soldiers during its first half-decade, Garvey’s Caribbean links were indispensable to the movement’s success, and the region ultimately proved to be its most important theater, contends Robert A. Hill in “The Marcus Garvey and Universal Negro Improvement Association Papers: The Caribbean Diaspora 1910–1920.” (more…)

*Samples of rock, sediment from beneath the sea-floor help explain quakes like Japan’s*

New samples of rock and sediment from the depths of the eastern Pacific Ocean may help explain the cause of large, destructive earthquakes similar to the Tohoku Earthquake that struck Japan in mid-March.

Nearly 1,500 meters (almost one mile) of sediment cores collected from the ocean floor off the coast of Costa Rica reveal detailed records of some two million years of tectonic activity along a seismic plate boundary. (more…)

Again, but Faster! The Spectacular Courtship Dance of a Tiny Bird

A small male bird called a golden-collared manakin performs a difficult, elaborate, physically demanding courtship dance. In new research, life scientists report that female golden-collared manakins select mates based on subtle differences in motor performance during these dances.

“The male jumps like he’s been shot out of a cannon,” said study co-author Barney Schlinger, professor and departmental chair of integrative biology and physiology and a professor of ecology and evolutionary biology at UCLA. “It’s exquisite. He sails like an acrobat and lands perfectly on a perch, like a gymnast landing a flawless dismount. Not only is there power to his muscle contractions but incredible speed as well.” (more…)

Smithsonian Researchers Report that Regional Sea Temperature Rise and Coral Bleaching Event Has Reached Western Caribbean

The Smithsonian Tropical Research Institute’s Bocas del Toro Research Station and Galeta Point Marine Laboratory are reporting an anomalous sea temperature rise and a major coral bleaching event in the western Caribbean. Although the U.S. National Oceanic and Atmospheric Administration, NOAA, issued an advisory in July announcing above-average sea surface temperatures in the wider Caribbean region, there had been no clear indication of increased sea temperatures in Panama and the western Caribbean until late August-early September.
