Objectives: a) TLW relate r- and K-selected characteristics to survivorship curves. b) TLW practice good scientific graphing techniques. Page 3. © Kristen Daniels

Survivorship curves and r and k strategists: K-strategists are slow growing and produce few, large offspring that mature slowly. R-strategists, slow and mature quickly and produce many, small offspring.

The names r and K come from a mathematical model of population growth, which is typically a sigmoid curve. For small populations, growth is exponential as

The behavior of an r strategist is dictated by its genes, which are naturally selected over geological time. This means that r strategists are self-sufficient and their behavior rarely goes wrong.

Intrinsic rate of increase (r) is the rate at which a population would grow if it Natural Selection has lead to two strategies for species: r - strategists and K – The way to represent the age structure of a population is with a s

In evolutionary terms, it is of no consequence if an organism is a fine, fully mature, physical specimen, or the dominant member of the herd, or even that an individual produces a lot of young but none of them survive.

For r-strategists, alleles that enhance What type of survivorship curves do k strategists and r strategists have? Asked by Wiki User. See Answer. Top Answer. Wiki User Answered 2012-08-21 17:30:49.

Survivorship: Gray wolves have a relatively even probability of survival throughout life which designates them as a species with a Type II survivorship curve (see Figure 3). The success and survivorship of individuals is closely linked to the pack because multiple animals contributing to the survival of both pack members throughout life.

Survivorship curve The overall survivorship curve for this population was similar to that of other marine mammals (Spinage 1972) (Figure 3). As expected, survival rates at all ages on the survivorship curve which considered both natural and bycatch mortality were lower than those of the survivorship curve that considered only natural mortality.

size •Most organisms begin to age once they have past maturity. Strength declines and they die as they reach the natural life expectancy. If we plot a survivorship curve for an r-strategist, it is apt to take the form of the curve labeled D. Although humans are not r-strategists, the higher birth rate in some countries may well be a response to their higher rates of infant mortality (curve B). They have efficient means of dispersal to new habitats.

-mix between K-strategists and R-strategists that have a median life span Type III Survivorship Curve -individuals in year right after birth die off in high numbers usually to predation -offspring are generally R-strategists that only live for a couple of years

Figure 7 illustrates a performance-time curve for overall domestic refrigerators and the effect of 1993 Standards legislation. Draw survival curves for males and females for each category (pre-post 1880). Questions. Compare the survivorship curves for males and females.

A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group (e.g. males or females). Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table. There are three generalized types of survivorship curves:

2018-02-15 · Wels catfish exhibit characteristics of both the r-strategist and the K-strategist, aligning more with the characteristics of the K-strategist. Although they produce thousands of eggs, with little parental investment, the species do have a medium to long lifespan, reproduce only once a year, and protect the eggs for a short period after they are laid (CABI, 2017, & Slone, 2006). Draw a survivorship curve for K-strategist.
