The more of the possible scripts that are run, the clearer the picture is likely to become. Thank you for anyone who will help, I really appreciate it! Which taxa ecologists choose to study is affected by taxonomic stability for those taxa and the set of taxa sampled and their intrinsic taxonomic stability, can create noise in statistical analyses. also i am interested to know what are the main objectives or questions of your researches that you answered using such indices. These must be similar to dissimilarities produced by dist. Taxonomic concepts are human constructs, including those for soils and geology, however, botanical taxonomy is based on living, adapting entities, which have variation within individuals, and through time as well as space. As expected, because of longer and uninterrupted evolutionary trajectory, taxonomic distinctness was higher in an undisturbed place.In the second case I was looking at carabid diversity in a forest and wanted to know whether competitive exclusion occurs more often among less distinct species or not (in other words, at high population densities whether taxonomic distinctness increased with decreasing species richness).In other works where I looked at plant diversity (over 20 such cases) I always used species richness, Simpson indices, rarefaction-estimated richness, etc. But the need arose from very ancient in all civilizations and biological diversity was born from ecology. The frequency of collection, and geographical broadness which provides the taxonomist with material to study, when establishing or reevaluating taxonomic identities, can vary a great deal in quality and quantity, even between closely related taxa.
Even, I have the opinion that the most perfect, the decimal metric, was thought from the system of Linnaeus, which evidently departed from the Socratic teachings, that is, from the understanding of the systems that existed in ancient Greece. How taxa are distinguished, is very much based on the level of familiarity with that taxon and its relatives, by the taxonomist making the initial decisions.
Did they decide some of these characters were more important than others, and only use those that gave the easiest results to follow, without looking closely at discrepancies? Biological diversity is by definition the analysis of variability at any scale, be it ecological or biogeographic (to point out the two extremes).
Humidity, temperature, etc. Ecologists have been upset before, by taxonomic changes to species they have already done studies with.National Museum of Natural History, La Habana, Cubairst, there is no alpha, beta and gamma taxonomy, but alpha beta and gamma diversity. Undoubtedly many of the processes that occur in an ecosystem can be interpreted and therefore expressed with the support of the taxonomy. Taxonomic Diversity Biodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. The lack of meaningful results from one approach, when another is more useful for a particular data set, may mean something significant in itself.National Museum of Natural History, La Habana, CubaThe taxonomy is the identification and description of taxa with the objective of locating them in a system. Two basic indices are called To achieve this, I use wealth in families, and how the wealth of each family is pondered.This had previously been done to study the Russian prairies by TolmachovInternational Institute of Information Technology, HyderabadWhat is the deference between Shannon Wiener diversity Index and Simpson diversity Index?i am more interest to know what kind of hypothesis, question, or objective that each index usually answer.
Some people prefer to focus on the best results, or avoid conflicts by sticking to one approach. However, I disagree with your statement that taxonomy and ecology have absolutely nothing to do with each other . Clarke, K.R & Warwick, R.M. (2001) A further biodiversity index Many ecologists choose to look only at taxonomically stable species, to avoid problems. (Maxwell and Dekkers 2019, Festivus, 51(3), 171- 176).Hi all, I am a student and my statistics knowledge is minimal. If resources allow, it seems important to sample several mixtures of taxa to compare ecosystems, and to look at some less stable species as well, that may be responding to changes in their surroundings.
The funding, capabilities, and attention given each taxonomic group also vary.
