• In recent years, the striped bass population in
  the Chesapeake Bay has been declining. This is
  due in part to fish kills, where a large number
  of fish die off. Fish kills occur when
  oxygen-consuming processes require more oxygen
  than the plants produce, which reduces the amount
  of oxygen available to the fish. One explanation
  is human activities that increased the amount of
  sediments suspended in the water, largely due to
  erosion from cutting down trees. The sediment
  acts as a filter for sunlight which causes a
  decrease in the amount of sunlight that gets to
  the aquatic plants in the Chesapeake Bay.

Reproductive Adaptations

• Spores asexual adapted for dispersal and
  survival in unfavorable conditions
• Ex fungi

32
Reproductive Adaptation

• Placental mammals sac of membranes that nourish
  young before birth. Complex development and
  protected longer.

33
Reproductive Adaptation

• External vs. Internal fertilization

External Fertilization Produces a large amount
of offspring, but most susceptible to predators
Internal Fertilization Protected offspring! But
you actually have to do the deed.
34
Reproductive Adaptation

• Sexual vs. Asexual

Asexual Energy Conservation. Exact Replica.
Sexual Genetic Variation.
35
Reproductive Adaptation

• Eggs

Soft In water, so they do not dry up. Lay more
to increase chance of survival.
Hard Protection on land. Nourishment.
36
Reproductive Adaptation

• Seeds

Protected embryo. Provides nutrients to embryo.
Aids in dispersal.
