Survivorship Curve:The survivorship curve is used to represent the number of populations that are expected to live to a certain age. There are three types of survival curves they are Type I, Type II, and Type III. Each curve will show the life expectancy of a particular group of ...
study it. We hypothesise that a Type-II survivorship curve displaying a constant mortality rate and relatively few older reproductive adults describes the majority of our ancestral demography, up until the Palaeolithic. A Palaeolithic, demographic shift towards the modern Type-I survivorship curve would...
We hypothesise that over the last 50,000 years, the human population survivorship curve has experienced a shift from one of constant mortality and no senescence (known as a Type-II population) to one of delayed, but strong senescence (known as a Type-I population). We simulate drift in ...
HALI induced morphological changes are dramatically reduced at 28 dpi in control mice, and although Klf5-deficient mice appear to have more and larger legions, this result could be due to survivorship bias (Figure S4C). In damaged zones at 28 dpi, AT2-AT1 cell differentiation levels are no ...
able to predict host performance under ambient conditions. If the goal is to produce more thermally tolerant recruits, then perhaps a trade-off in initial size/survivorship would be acceptable. Further research on the thermal tolerance of coral–symbiont assemblages is underway and will provide more...
