The trend showcased in the survivorship shown in the graph is highlighted by a big drop-off in early ages with a steadier decline later on. This survivorship curve most likely represents a Type III survivorship curve, and this is due to the fact is that this curve has a high death rate in early ages, which is prominent in the characteristics of a Type III survivorship curve.
Exponential decay is characteristic of type II populations, not type III. The y axis on the original graph in the video (whale, squirrel, & dandelion) used a log scale. A straight line (Type II) on a semi-log graph like this represents exponential decay. Note that it takes the same time for the type II squirrel population to drop by 90% from 1000 squirrels to 100 as it does for the squirrel population to drop 90% from 100 to 10. That is exponential decay. The graph for this example does not use a log scale on the y-axis, so it is a bit confusing to use this as an example after using semi log graphs in the video. The % survival from 0-1 yrs is ~ 60% from 1-2 years it is roughly 60% ( .6x.6 =.36 @ 2years.) This means that for the first two years this was behaving like a type II. (except for the males, which all inexplicably died off after 2 years. Black Widow Spiders? Praying Mantisses?) Thereafter the survivorship declines almost linearly, which is more characteristic of type I. (If you have a straight downwards sloping graph and replot it as a semi log graph, it will be concave downwards.)
In the graph shown, we can see a high mortality rate, during infancy. The mortality is still high during midlife and adulthood but it is less than during infancy. This represents a type 3, in which most offspring die off early in life, and few make it to midlife, and even fewer to adulthood.

😷 I know Smedes is following CDC guidelines because he has this new video format LOCKED DOWN ! I'm digging these new videos Smedes!

the trend in the graph dropped exponentially at the start(year 0-2), and declined slower steadily after. This will be a type 3 survivorship curve

@@simonwesley9283 you're so helpful thank you!
these are absolutely fantastic - thank you so much -can you post a link to the slide presentations for each unit?
I think its in his link tree
