The Story of the Key Deer<br />How animals adapt to dynamic ecosystems<br />
Characteristics ofOdocoileusvirginianusclavium<br />Smallest species of white-tailed deer<br />Subspecies of the Virginia white-tailed deer<br />Inhabit around 20-25 islands in the Keys<br />75% of the deer are found on Big Pine and No Name Keys<br />Are the deer a metapopulation?<br />Found nowhere else on Earth<br />Endangered Species<br />By the mid-1940’s there were less than 50 alive<br />1957- The National Key Deer Refuge created<br />By 2000, there were between 600 to 800 deer<br />

Females average weight is 100lbs and males average 150 lbs.
Gestation is 10 months and fawns are between 15-20 lbs at birth
Does usually have one to three fawns per year.</li></li></ul><li>Why are they so small?<br />What are your theories?<br />Why do you think that?<br />
Looking further…<br />The key deer rely on having freshwater to live on. Some of the islands do not have freshwater sources. <br />The deer are herbivores. <br />What is an herbivore?<br />
What are Adaptations? <br />Natural Selection – <br /> survival of the fittest<br /> organisms that are best able to survive in an environment survive<br />Why is this important in a dynamic ecosystem?<br />What would have happened if the Key Deer were as large as a deer you would see in your backyard?<br />
