We shall now look into some of such important graphs in R. This part of the tutorial focuses on how to make graphs/charts with R. In this tutorial, you are going to use ggplot2 package. This package is built upon the consistent underlying of the book Grammar of graphics written by Wilkinson, 2005. ggplot2 is very flexible, incorporates many themes and plot specification at a high level of abstraction. K and r are two extremes for a range of population growth strategies, no one strategy is better or best. Identify the characteristics associated with K selec So basically you want the plotting area (area inside the x and y axis) to be the same for multiple graphs. This is an issue I have found with using ggplot2 as well. One solution is to pass each plot through the align_plots() function in the cowplot package: Species richness.

R selected species graph

In Excel, graphs are made by manually selecting options - which, as we’ve discussed previously, may not be the best option for reproducibility. Also, if we haven’t built a graph with reproducible code, then we might not be able to easily recreate a graph or use that code again to make the same style graph with different data. 30 Jul 2018 Population growth curve in an ecosystem, with exponential growth r and The r/ k selection theory explains whether a species chooses to be a For example, the type II curve has a constant proportion of individuals dying each In general, this is more typical of K-selected species, which tend to grow in Exhibit Jshaped growth curve. Impacted by density – independent factors.

2016-05-30 · • Species that are r-selected ~ less interspecific competition – Hence, evolve no mechanisms for strong competitive ability • Algae, bacteria, rodents, annual plants, sardine, squid, krill and most insects • They reproduce and disperse rapidly when conditions are favorable or when a disturbance opens up a new habitat or niche for invasion, as in the early stages of ecological succession

filter (): Extract rows that meet a certain logical criteria. For example iris %>% filter (Sepal.Length > 6). • R- selected species are characterized by small size, high growth rate and short cell cycle and are able to increase in population rapidly under conditions of low population density and low species competition. These organisms are particularly prominent in temperate lakes during the clear-water phase.

Compare a J-shaped growth curve with an S-shaped growth curve and comment on Define r-selected species and K-selected species and compare the two.

The R-selected species are those with a higher growth rate, yields more offspring, but with a lower rate of survival.
