WebOct 11, 2010 · Bacterial populations harbor vast genetic diversity that is continually shaped by abiotic and biotic selective pressures, as well as by neutral processes. Individuals … WebIn contrast, biotic selective pressures, in the form of nest predation, favoured non-local, temperate nests, with temperate nests fledging one young per nest more, on average, than local subarctic nests (figure 2a). The lower predation rates on non-local temperate nests may have been caused by their smaller relative size, their cryptic ...
