CHARACTERIZING PATTERNS IN TEXAS GULF COAST BEACH DUNE PLANT SPECIES COMPOSITION
… were analyzed using cluster analysis, ANOSIM, SIMPER, NMDS, and ISA for fives zones representing the foredune complex of twenty Gulf Coast beaches. ANOVA revealed that zones differ in terms of percent bare sand, percent vegetative cover, and species richness. Cluster Analysis, ANOSIM, …

Bycatch of the Lake Pontchartrain Basin inshore shrimp fishery and its effect on two sea catfish species: the gafftopsail catfish (Bagre marinus) and the hardhead catfish (Ariopsis felis)
… assemblages using analysis of similarity (ANOSIM) and determined important species by weight and abundance using similarity percentages analyses (SIMPER). I also examined differences in size-class distributions by gear type using density kernel plots and Mann-Whitney U tests. The two gear …

Microbial community analysis for denitrifying biofilters
… MDS plots, and a new geostatistical method—ANOSIM-GS—developed for this research. ANOSIM-GS provides a robust way to characterize the variation of ecological communities with separation of space or time. Using these tools, significant spatial variability in overall bacterial (ARISA) …

The Bees of Two Sites in the Big Thicket National Preserve, Texas, with a Consideration of the Effects of a Rare Flooding Event
… the multivariate tests analysis of similarity (ANOSIM) and similarity of percentages (SIMPER). At two sites over two years of sampling 100 species were documented. Though some species declined dramatically following the storm, it was concluded that the overall bee community did not suffer a …

Taxonomia e aspectos ecológicos de Tanaidacea (Crustacea: Peracarida) da plataforma continental e bancos oceânicos do nordeste do Brasil, coletados durante o Programa Revizee-NE
… analisados através da análise de similaridade (ANOSIM), escalonamento multidimensional (MDS), análise de agrupamento e BIOENV. Para a composição faunística foram identificados 34 espécies, 22 gêneros e dez famílias, dentre as quais 13 são novas para a ciência, dez novas ocorrências, incluindo …

Biodiversidad específica de los Opiliones (Arachnida) dentro del paisaje en mosaico del centro de Asturias
… sustentada estadísticamente por el análisis ANOSIM: los prados están completamente separados del resto, los bosques y prebosques de la ladera norte quedan agrupados y los puntos de la cima y la ladera sur del monte Naranco forman otro cluster. Las plantaciones aparecen disgregadas, en …

Effects of Stream Crossings on Macroinvertebrate Assemblages of the Upper Current River, Ozark National Scenic Riverways, Missouri
… Multivariate analyses (NMDS and a nested ANOSIM) also revealed strong differences in community composition among sites, as well as among locations. Taken together, the results indicate crossing disturbances during summer and winter 2009 were either too infrequent or small in intensity to …

Effects of iso-alpha-acids on rumen fermentation and comparison of microbial populations between rumens and continuous culture fermenters
… variance (AMOVA) and analysis of similarity (ANOSIM) based on Bray-Curtis dissimilarity matrices. Differences in taxonomic composition of different sample types were analyzed at kingdom, phylum, class, order and family taxonomic levels. Functional inferences were made by matching taxonomic …

Interpreting Predator – Prey Interactions in Cayuga Lake Fishes Using Fatty Acid Signature Analysis
… FAS of both prey species differed significantly (ANOSIM, overall R = 0.594; P < 0.05); concentration of 18:1n-9 was highest in alewife, whereas 22:6n-3, 20:5n-3, 16:1n-7, and 18:3n-3 concentrations were highest in round goby. Intraspecies (spatio-temporal) FAS variations were found for each prey …

Biodiversity survey towards conservation of subtidal reef habitats in KwaZulu Natal : biogeography and depth patterns
… separation at Cape St Lucia. Pairwise ANOSIM tests found no significant differences in community composition of reefs along a depth range of 10 m to 30 m at nine localities in KZN. However, differences among localities were significant at both regional (R = 0.607, P = 0.1%) and local (R …

Effect of Standard Post-harvest Interventions of Fresh Vegetables on Bacterial Community Dynamics, Pathogen Survival and Antibiotic Resistance
… by the weighted Unifrac distance matrices (ANOSIM, R=0.465). Storage of sanitizer-washed carrots at 10ºC was associated with an increase in relative abundance of Pseudomonadaceae compared to 2ºC storage for 7 d (Wilcoxon, p<0.05). Increase in storage temperature from 2ºC (optimum) to 10ºC …

Sessile Invertebrate Colonization on Rocky Outcrops at Gray's Reef National Marine Sanctuary
… of the study, but analyses of similarities (ANOSIM) did provide evidence of convergence over the long term. These results indicate that succession of sessile invertebrates is not a predictable process in this system and that the extant community plays a role in deciding the final outcome of …

Effects of Organic and Conventional Agricultural Practices on Soil Microbial Communities and Molecular Detection of Soil Borne Disease
… and animal communities were unique to each farm (ANOSIM PSclerotium<em>rolfsii</em> DNA (P=0.0454 and P=0.0278 respectively) in the inoculated than un-inoculated soil measured by quantitative polymerase chain reaction (Q-PCR). Fluorescent in situ hybridization (FISH) was used as an alternative for …

Patterns in Fish Community Structure in a Regulated River
… pre or post peaking samples, sites, or years (ANOSIM p < 0.05). I concluded that the small amount of fish community variation observed supports the possibility that the present assemblage has adapted to a regulated flow regime, however a direct relationship between peaking and community …

Soil Microbial Community Distributions And Disease Suppressiveness In The Coastal Plain Of Georgia
… metazoan communities by analysis of similarity (ANOSIM) revealed high within-group similarity by vegetation type, indicating land management intensity and vegetation cover is a strong determining factor in community similarity. Further analysis of fragments obtained by LH-PCR revealed that fungal …

Amphibian Community Similarity Between Natural Ponds And Constructed Ponds Of Multiple Types In Daniel Boone National Forest, Kentucky
… (CCA) and one-way analysis of similarity (ANOSIM). Stepwise regression models were developed to predict individual species abundance based on the habitat variables. Amphibian communities differed significantly between ponds types (natural, new construction method, old construction method). …

Variation in diet of the West coast rock lobster (Jasus Ialandii) : influence of rock-lobster sex, size and food environment
… percentage of large rock-lobster diet. ANOSIM (Primer v 4.0) established significant differences (p < 0.05) among diets of the three size classes. Differences in diet were also observed between areas of fast- and slow-growth rates, but these were limited to the small and medium size …
