NIH In this issue of Molecular Ecology, Castro and colleagues have provided the first global-scale assessment of population structure for the largest fish--whale sharks (Rhincodon typus). For example, the migration of human populations from equatorial regions toward northern climates, where they were exposed to relatively low amounts of sunlight, resulted in changes over time in skin pigmentation, with skin becoming lighter in colour to augment vitamin D absorption (vitamin D is critical for proper bone development). This isn't the sort of thing anyone should be writing in a report - even if you're the worst student ever (which I fail to believe, as you're on this site) constructive criticism is what is needed. "Shallow end of the gene pool" basically means you're dumb. A large and diverse gene pool, for example, may improve a population’s chances for future adaptation to changing environmental conditions. Particular emphasis has been placed on the threat to biodiversity and the possible loss of as yet unknown and unexploited pharmaceuticals contained in the…. Adv Mar Biol. The ability of a population to adapt and evolve is thought to be influenced in part by the size of its gene pool. Do you have brothers or sisters at the school?

Swimming in the deep end of the gene pool: global population structure of an oceanic giant. At 24, he's a Super Bowl QB. This is largely due to the difficulty of observing wide-ranging marine species over the majority of their life cycle. The advent of powerful tracking devices has certainly improved our understanding, but it is usually only with molecular tools that the nature of population structure becomes apparent. Sieving a living: a review of the biology, ecology and conservation status of the plankton-feeding basking shark Cetorhinus maximus. 0.

Despite the impression held by some that few biological mysteries remain, even evocative species such as humpback whales (Megaptera novaeangliae), white sharks (Carcharodon carcharias) and green turtles (Chelonia mydas) have poorly documented movement patterns, reproductive strategies and population dynamics despite years of dedicated research.
