Ranked species abundance plot or k-dominance plot (Warwick et al., 2008) computed for the post-monsoon season revealed an elevated curve, indicative of minimum diversity and maximum dominance …

In the graph on the X axis you put the species rank, and on the epsilon axis you put the cumulative relative abundance and you obtain the K-dominance curve.

Tropical Ecology 29: 136-145. Are there any scripts that have successfully worked for other people in this situation? I want to know, how does one calculate dominance diversity curves.

Journal ofWilson, J. It overcomes the shortcomings of biodiversity indices that cannot display the relative role different variables played in their calculation. ROUT S. K. and S. R. GUPTA (1989) Analysis of forest vegetation of Morni hills in north-east Haryana. A rank abundance curve. Could anyone explain the difference or suggest a good reading? Dominance diversity curves were constructed by ranking the log of the species density values from highest to lowest. At site 1, I detected 52 species, and over 700 individuals. & Wilson, J.

Species richness can be viewed as the number of different species on the chart i.e., how many species were ranked. The y axis then displays the proportion as a percentage on a linear scale.I would like to display the proportion as a proportion of 1, and on a log scale.Does anyone know / can anyone think of a way to do so or an elegant workaround, either with this package or another?Does anyone know scripts to calculate beta diversity in R for larger data sets?Hi, I am using R to compute the alpha, beta and gamma diversity of a landscape which has been split into 27 grids.

(1991) Methods for fitting dominance/diversuty curves.

K-dominance curve is a powerful tool for measuring abundance trends in communities over time. At site 2, I only detected 25 species and about 200 individuals. Because my data also contained abundance information, I thought of using the Bray-Curtis measure. ThanksWhat is the best method to analyze change in species composition over three years in different sites?I sampled a community of insects in different sites in three years and I would like to calculate the between site and between year differences respective change in species composition. A shallow gradient indicates high evenness as the abundances of different species are similar.

can any one help me to interpret this meaningfully. DisponívelWatkins, A. J. Please let me know how to plot the graphs for it. Curves of decreasing productivity connect the few most important species (the dominants) with a larger number of species of intermediate importance (whose number primarily determines the community's diversity or richness in species) and a smaller number of rare species.

I want to know, how does one calculate dominance diversity curves. I used the Shannon-Weiner index to get similar H values for each site, but I'm not sure how to compare those values.Would you recommend another method of comparing diversity, or is there another statistical analysis that can be applied to my Shannon index values?Can anyone help me in understanding and clearly interpreting ANOSIM (Analysis of Similarity)and SIMPER (Similarity percentage analysis)results?I used PRIMER-E software to perform ANOSIM and SIMPER analysis.

I do not know exactly how to separate spatial from temporal effects as well how to distinguish between differences in number of occuring species and the identity of the occuring species (that is if the species richness is the same, the identity of the species may not be the same).Join ResearchGate to find the people and research you need to help your work.© 2008-2020 ResearchGate GmbH.
