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.
(In biology) The bottleneck effect happens when the size of a population or even an entire species is suddenly reduced, with lasting effects on at least one generation.A popu â¦ lation bottleneck may occur after an epidemic, drought, fire, hunting, or other destructive events.ottleneck effect is an evolutionary event in which population size is radically reduced because of catastrophic events. founder effect occur when few individuals migrate fr â¦ om main population and establishes a separate population in new geographical location.
