Stochastic Dynamics Models of Plant Population and Species Diversity
… presents sophisticated error analysis of the Shannon index in time and space. Error of current estimate increases proportional to measurement while the total forecasting error increases very fast in time. Spatial variation contributes the most to the total error of the Shannon index. Even …

Bacterial and archaeal community structure across a gradient of saline lakes in Kiritimati, Republic of Kiribati
… saline samples had both higher and lower Shannon index values, whereas lower salinity groups showed a range of Shannon index values. Our findings suggest pH may interact with salinity to influence microbial community structure and that diversity at high salinities may be controlled by both …

Groundfish species diversity and assemblage structure in Icelandic waters during a period of rapid warming (1996-2007)
… tveir fjölbreytileikastuðlar; fjöldi tegunda og Shannon index. Tengsl fjölbreytileika og hitastigs, dýpis, frumframleiðslu, staðsetningar og ára voru könnuð með GAM líkönum (generalized additive models). Fjögur meginsamfélög með útbreiðslu í suðvestur-djúpi, norður-djúpi, suður landgrunni og með …

Ecology of Lactobacillus in the gastrointestinal tract of the weanling piglet
… a 23S rRNA gene probe. Data was analyzed using Shannon, Simpson and, evenness diversity indices. The biotype and RFLP data was subjected to cluster analysis, and the clusters were defined as operational taxonomic units (OTU). The phenotypically typed bacteria, and data based on OTU were used as …

The Functional Properties and Digestibility of Round and Wrinkled Pea Flour in Swine
… WPF compared to those fed RPF (P < 0.05). The Shannon index, measure of microbial diversity within a sample, revealed that WPF-E fed to pigs decreased microbial diversity compared to those fed RPF-E (P < 0.05) in ileal samples. There was no significant difference in Shannon index among …

The Impact of Nutrient Loading from Canada Geese (Branta canadensis) on Water Quality, a Mesocosm Approach
… group. Phytoplankton diversity (using the Shannon index of diversity) was significantly decreased by the addition of goose feces (H1'=0.575, H2'=0.433, t=l7.43, p< 0.001, where H1' is the control and H2' is the 12.090 g treatment). We performed a settling experiment which suggested that …

Relationships between loblolly pine (Pinus taeda L.) yield and woody plant diversity in Virginia Piedmont plantations
… area (PHWD BA) and overstory plant diversity (Shannon index (H’)) decreased. Understory percent woody cover, and woody plant species richness, evenness, and diversity (H’) were not affected at any of the competition control levels. Regression analysis was used to determine relationships between …

Habitat Ecology, Trophic Interactions, and Distribution of Endangered Himalayan Musk Deer in the Nepal Himalaya
… deer’s diet. Dietary breadth measured by the Shannon index was found higher in winter compared to summer. Although musk deer and livestock shared a considerable number of plant species in their diets, the consumption however was significantly different in terms of abundance of the species …

Further elucidating the effects of ruminal and hindgut acidosis on the ruminant animal
… observed amplicon sequence variants and Shannon index were decreased (P < 0.01) in HGA ewes compared with CON. Furthermore, HGA ewes had greater (P < 0.01) relative abundance of Bifidobacterium, Streptococcus, and Limosilactobacillus in cecal contents than CON ewes. In feces, …
