Editor’s Selections: Compensating for alien genes, natural selection, and freshwater aquaria as vectorsMay 14th, 2010 Editor's Selections 7 Comments
Vincent Racaniello selects several notable posts each week from molecular and cellular biology and virology. He blogs at virology blog.
- Resistance to bacterial antibiotics encoded on plasmids or the chromosome initially results in loss of fitness. But the cost may often be ameliorated without the loss of resistance.
- The best-known of the Big Four forces of evolution is almost certainly natural selection. It is a relationship between fitness, the number of offspring an organism can produce, and phenotype, the value of one or more traits of that organism.
- One of the pleasant surprises of a freshwater aquarium is the invertebrate organisms like snails and worms that show up and call your tank home. Unfortunately, the introduction of exotic invertebrates could pose a problem for natural freshwater systems.
I’ll be back next Friday with more selections.
