In this study, we evaluated how cichlid assemblages are affected by seasonal and interannual variations in water volume in the floodplain lagoons of the Cuiabá River in the Pantanal wetland. Eleven lagoons were sampled in the early dry season and the early rainy season over a three-year period. Analysis of similarity (ANOSIM) showed that the species compositions and relative abundances were distinct between the seasons, which indicates that neither persistence nor stability was maintained on a seasonal basis. However, the interannual comparisons show the opposite tendency, indicating strong stability and persistence on an annual basis. These results indicate that the cichlid assemblages in these lagoons have two equilibrium points, one in the early dry season and the other in the early rainy season, and that the assemblages alternate between these points through the hydrologic cycle. In addition to the effect of the water level variation, the abundance distribution is also affected by conductivity and pH, which also influence the total abundance of the species in the assemblage.

“…Distance matrices were analyzed with cluster analysis to describe spatiotemporal shifts in faunal composition. Hierarchical cluster analysis was used to assess patterns in faunal similarities among rivers using an overall distance matrix from both assessment periods and separate distance matrices from each assessment period (Hansen and Ramm, 1994;Hoagstrom et al, 2007;Gido et al, 2010). Ward's minimum variance linkage was chosen to construct cluster dendrograms.…”

“…Ward's minimum variance linkage was chosen to construct cluster dendrograms. Ward's linkage is able to retrieve clusters from a variety of data structures and has been shown to consistently provide better classifications than most agglomerative linkages when data overlap in multivariate space (Milligan and Cooper, 1987;Hansen and Ramm, 1994). To aide in the interpretation of clusters within dendrograms, we evaluated cluster significance with a post hoc bootstrap resampling procedure.…”

Historical change in fish assemblage structure was evaluated in the mainstems of the Des Moines, Iowa, Cedar, Wapsipinicon, and Maquoketa rivers, in Iowa. Fish occurrence data were compared in each river between historical and recent time periods to characterize temporal changes among 126 species distributions and assess spatiotemporal patterns in faunal similarity. A resampling procedure was used to estimate species occurrences in rivers during each assessment period and changes in species occurrence were summarized. Spatiotemporal shifts in species composition were analyzed at the river and river section scale using cluster analysis, pairwise Jaccard's dissimilarities, and analysis of multivariate beta dispersion. The majority of species exhibited either increases or declines in distribution in all rivers with the exception of several "unknown" or inconclusive trends exhibited by species in the Maquoketa River. Cluster analysis identified temporal patterns of similarity among fish assemblages in the Des Moines, Cedar, and Iowa rivers within the historical and recent assessment period indicating a significant change in species composition. Prominent declines of backwater species with phytophilic spawning strategies contributed to assemblage changes occurring across river systems.

“…Traditionally, this binary similarity coefficient is used to measure the similarity between two sites, usually a reference or unimpaired site and a site of interest or impaired site. But the JCS can also be used to assess changes in species composition between two sites by providing one metric that reflects changes in composition through time (Hansen and Ramm, 1994). Unlike other similarity coefficients, Table 2.…”

Fish assemblage collections were assessed in sub-watersheds containing various land use types to relate overall biotic condition to patterns of watershed disturbance and to the influence of introduced fishes. Four hundred historical and contemporary fish collections were analyzed in conjunction with land use and land cover data among 200, first-through fourth-order sub-watersheds across Pennsylvania. A high degree of collinearity among several land use types and the presence of non-indigenous fishes was determined, indicating multiple anthropogenic influences. Significant relationships were found between various land use types and the Jaccard coefficient of similarity, the primary index used to evaluate changes between fish collections, across all major drainages. In general, the Jaccard coefficient of similarity increased to a value of one as the percentage of forested land increased, while the Jaccard coefficient of similarity decreased as percentages of agricultural and urban land increased. Sub-watersheds that showed declines in species richness had significantly higher percentages of agricultural and developed land, while those sub-watersheds with higher amounts of forested land appeared relatively stable. Seventy-percent of those species that experienced declines were either insectivores or benthic insectivores. The largest increases among the fish guilds occurred within the insectivore-piscivore group. We conclude that land use influences at the sub-watershed scale and the introduction of non-indigenous fishes have had a significant influence on fish community composition.
