Population Growth
The sumatran tiger is a very amazing tiger, but unfortunately is very endangered. This tiger generally keeps to itself, except when mating. The birth rate of this tiger is fairly low, but when the volcano killed the few that were on the island, it doesn't seem like it'd be that big of deal, being that only a few tigers died. In percentages however, that number is huge. The death rate likely didnt change that much other than just a few extra dead tigers, but the birth rate did, sense the few dozen tigers that probably died from the volcano can't mate and re populate, dropping the birth rate percentages quite a bit.
No record of exponential growth really exists for the sumatran tiger, but it was never very large in the first place, and up until about 1978, the tigers were increasing up to 1000 tigers on a single island. It likely leveled during this time for a little bit, but then after 1978 the population started to drop. Logistic growth likely occurred before 1978, but leveled a little. Like all populations, they level out but still go up and down in numbers a little, but in 2008 it dropped way to much, especially for an endangered species. Having numbers as little as a few hundred is a very serious issue.
The Krakatoa volcano took out nearly two thirds of the island after the eruption, and that space that was taken up is a lot of land and carrying capacity that was wasted into the water that leaves much less room for new life to move in.
Density dependent limiting factors are when the density of a population has an effect, whereas independent limiting factors are when the density of the population has no effect. A dependent limiting factor would be that there were less tigers after the eruption, making less food required to feed the necessity amount of tigers. This is kind of like the bright side of a bad situation, sense there were less tigers, the amount of food needed to feed them reduced, making the few tigers left easily able to adapt and find food easier. A independent limiting factor would be that sense part of the island sunk, the available room for organisms dropped as well.
Overall, the sumatran tiger would have a very hard time repopulating the island after the eruption for a long time. Succession would have to had fully happened, and then the tiger would have to find a way to live on such a, now, small island and still live and repopulate, despite the much smaller carrying capacity of the island for tigers.
