31. Lowering the amount of fungicide in the environment lowers the selection pressure for resistance to develop. 32. However, these traits must be chosen carefully, as different traits are affected by different selection pressures . 33. There would be intense selection pressure for any of their young that inherited the same trait. 34. Piglet survival also depends on selection pressure . 35. :To echo Someguy1221 humans are constrained by different selection pressures to animals that lack language and culture. 36. Reduced forage density leads to a conflict between sexual selection for antler size and nutritional selection pressures . 37. This exchange of genes between different bacteria enables rapid emergence of resistance under selection pressure of antibiotics. 38. Thus, it seems that such plants have evolved egg dummies under selection pressure from these grazing herbivore enemies. 39. This increases selection pressure towards resistance. 40. In these species, there is a selection pressure for whatever traits enable a male to have more matings.
