The Abaco Islands. The Abaco Islands consists of several islands and cays (very small islands) that are great for exploring and snorkeling. Andros Island is the Bahamas' largest island but it's also the least developed. Like other Out Islands, Andros Island is ideal for eco-travelers.
bottleneck (bÅt'l-nÄk') An abrupt and severe reduction in the number of individuals during the history of a species, resulting in the loss of diversity from the gene pool. The generations following the bottleneck are more genetically homogenous than would otherwise be expected. Bottlenecks often occur in consequence of a catastrophic event.
However, a road need not narrow for a recurring bottleneck condition to result: e.g., witness a weave condition, sun glare, or a vertical climb. For that reason and others, in the context of traffic analysis, there are recurring and nonrecurring causes of bottlenecks, which invariably shapes one's definition.mong Webster's dictionary definitions of bottleneck are i) a narrow or obstructed portion of a highway or pipeline, and ii) a hindrance to production or progress. Certainly the elemental roots of a traffic bottleneck exist in these descriptions; namely, the narrow portion of highway and the hindrance to progress.
