WebThe Brillouin index measures the diversity of a collection, as opposed to the Shannon index which measures a sample. Pielou (1975) recommends this index in all situations where a collection is made, sampling was non-random or the full composition of the community is known.

WebThe differences in the Brillouin index between the infracommunities of partridges and pheasants were analysed using the Mann-Whitney U test in STATISTICA software v. 13.1 (StatSoft Polska, Krakow, Poland). Parasitological indices, i.e., prevalence, mean intensity of infection, and range of intensity, were calculated [ 39 ]. Webuniverse. The Shannon index is based on percentage composition by species. Consequently, under these conditions and with increasing sample size, the index approaches a constant value, as do related diversity indices such as those of Simpson (1949) and Mc-Intosh (1967).

WebMar 1, 2024 · Brillouin's index estimated a diversity index of 3.545, with a relative value of high diversity (MacDonald 2003). The three diversity index proved that the LMF has a diversity value of high to very high species diversity, with an evenness index of 0.827 or 83% of species are common or shared among plots within habitat types (Figure 4). WebThe species richness of parasites varied from 1 to 9, the Brillouin diversity index from 0 to 1.52, evenness from 0 to 0.63 and the Berger-Parker dominance index from 0.39 to 1.00. Abundance of parasites was not influenced by host length, but there was significant correlation with host body weight in some cases.

WebDec 4, 2024 · Brillouin diversity index. The Brillouin index describes a known collection: it does not assume random sampling in an infinite population. Pielou (1975) and Laxton (1978) argues for the use of the Brillouin index in all circumstances, especially in preference to the Shannon index. WebMcIntosh's Index is based on a geometric model: u = (Ni2) e.g., N=7; N1=3, N2=4 u = (Ni2) = (32+ 42) = 5 = length of vector from origin e.g., N=10; N1=2, N2=3, N3=5 u = (Ni2) = (22+ 32+ 52) = 6.1644 From this, McIntosh defined an equitability index: M = N - u An obvious disadvantage is that M = f(N); however, M can be normalized (Peet 1974):

WebApr 24, 2024 · However, the Brillouin diversity index, evenness and Berger–Parker dominance index did not differ between the two seasons (Table 2). In the dry season, there was predominance of hosts parasitized by four to five species; and in the rainy season there was predominance of hosts parasitized by five species (Fig. 2 ). WebAs such, the Brillouin diversity index was used to describe the songbird community for each treatment based on territories of each species (Zar 1996). A one-way analysis of variance (ANOVA) of the Brillouin diversity index was used with a post-hoc least squared difference test (LSD) to test for differences between treatments.
