Crisis of confidence averted: Impairment of exercise economy

r-selected species are adapted to unstable and unpredictable environments. They have large numbers of small offspring. Animals that are r-selected do not provide a lot of resources or parental care to offspring, and the offspring are relatively self-sufficient at birth. Examples of r-selected species are marine invertebrates such as jellyfish and plants such as the dandelion. The two extreme strategies are at two ends of a continuum on The r/k selection theory proposes to explain the reproduction strategies of species with respect to their environmental characteristics. Ecologists of the 1970’s categorized species into two categories: those that lived in stable environments and those that lived in unstable environments with many environmental stresses threatening the Members of an r-selected species characteristically: Carrying capacity.

Differentiate between r and K population growth strategies. Give at least two examples of each ﴾that we have not discussed already﴿ 2. For each example in Figure 8, determine whether the population is made up of rselected organisms or Kselected organisms. Justify your answer. 3. Combining these two can get you something like plot(uh, type="n", dis="sp") followed with text(uh, dis="sp", select=goodness(uh, prop=T, summarize=T) > 0.2).

Origianlly based on Leland Wilkinson's The Grammar of Graphics, ggplot2 allows you to create graphs that represent both univariate and multivariate numerical and categorical data in a 2019-01-13 In biology, this is called r-K selection: in an r-situation, organisms will invest in quick reproduction, in a K-situation they will rather invest in prolonged development and long life. Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy. This tutorial describes how to subset or extract data frame rows based on certain criteria.
