The long-running U.S. embargo has failed to topple the Castro regime in Cuba, but has done a good job of stymying research on anoles. Despite its great biodiversity, less is known about the Cuban fauna and flora than other Caribbean islands (despite the great efforts of Cuba’s excellent scientific establishment). I can speak from personal experience in saying that even though scientific research is one of the exemptions in the U.S. embargo law, getting permission from the U.S. and Cuban governments to work there has often been difficult. Recently (and probably still the case, though the U.S. government’s interpretation of the law is constantly changing), graduate researchers, in particular, have troubles because they are not considered “full time professionals” and thus not eligible to travel there under the research exemption.
Let’s hope that all restrictions are lifted soon so that the marvelous biodiversity of Cuba can be observed, studied, and conserved.
