Summary Introduction
To describe: Type I, Type II, and Type III survivorship curves and explain how life tables and survivorship curves indicate mortality and survival.
Introduction: The ability of individuals to survive and reproduce is affected by the given life history traits of that population. An individual species is called fit when it reproduces successfully and makes a genetic contribution to the future generation. The probability of an individual to survive until a particular age is known as survivorship. Survivorship curve refers to plotting the logarithm of the number of survivors to their total life span.

- To create a survivorship curve for the Andean condor: Graph Title: Survivorship Curve for Andean Condor Y-axis: Labeled "Survivorship" with indicators for "Low," "Medium," and "High" levels, ranging from 0 to 100% of the total initial cohort size. X-axis: Labeled "Life Span" with stages "Young" (0-5 years), "Middle-aged" (6-37 years), and "Old" (38-75 years). Key Features of the Curve: Begins high, reflecting near-total survival from birth to maturity due to low mortality and protected upbringing. remains flat and high through the middle age, indicating sustained low mortality. shows a steep decline in old age, representing increased mortality as individuals reach the latter part of their lifespan.arrow_forwardDescribe how age-structure diagrams and survivorship curves are used to predict future growth.arrow_forwardWhat is the key characteristic of a population exhibiting a type II survivorship curve? large numbers of small offspring all individuals of all ages have an equal chance of dying younger individuals have a greater chance of survival younger individuals are more likely to die than other individualsarrow_forward
