Alpha and beta diversity of phytoplankton in two subtropical eutrophic streams in southern Brazil

This paper reports the alpha and beta diversity of phytoplankton communities of two streams differing in land use. We analyzed which environmental conditions affect diversity of the phytoplankton communities and tested the hypothesis that stream stretches protected by forests will have lower species richness, whereas higher beta-diversity would occur among the non-protected stretches. Samples were taken quarterly, from February to November 2012, in nine stretches, including four non-protected stretches, two partially protected stretches and three totally forest-protected stretches. Eleven abiotic variables and their coefficients of variation were analyzed. Phytoplankton was analyzed for species richness (alpha diversity), frequency of occurrence and beta-diversity. Species richness was calculated by first and second order jackknife indexes. Biotic data were submitted to Sørensen similarity analysis. A total of 429 infrageneric taxa were reported, representing 88% of the estimated expected species richness. The phytoplankton composition was typical for lotic environments with high richness values of Bacillariophyceae (66.0%). High phytoplankton richness values occurred in all the sampled stretches, even though beta-diversity was moderate and indicated similarity between the sampled stretches, therefore only a part of the original hypothesis was corroborated.

The great biodiversity of the Serra da Bodoquena is the result of years of biological evolution. A complex combination of natural factors allows aquatic plants, fish and invertebrates to coexist in absolutely crystalline water springs. Together, organisms form an intricate web of life, connecting a single-celled microalga with large river predators. For better knowledge of the biodiversity of microalgae, an important tool is the bioprospecting and study of novel species, avoiding as much as possible the introduction of exotic species. Thus, the aim of this work was bioprospecting microalgae species from Bonito, MS, Brazil, in order to obtain more information about the local microbial biodiversity. Freshwater samples were collected from two lakes of the municipality. The samples were plated in Basic Basal medium added of bacteriological agar. After plating, the samples were kept in a biochemical oxygen demand (BOD) oven at 25ºC with photoperiod for growth. After isolation of the obtained colonies, the identification of the species was carried out according to the morphological characteristics of cells. Despite the long periods for adaptation, seven microalgae taxa were successfully isolated from the samples collected, four at the genus level and three at the species level; one from the Trebouxiophyceae class, five from the Chlorophyceae class and one from the Bacillariophyceae class.

El estudio de algas del perifiton en humedales tropicales, permite interpretar la dinámica de estos ecosistemas con importancia ecológica y con vocación para ofrecer diferentes servicios a la población humana. El propósito de este trabajo fue determinar la estructura del ensamble ficoperifítico y evaluar su agremiación o preferencia de sustrato (macrófitas), en una ciénaga tropical. Se registraron 48 especies, los grupos de clorófitas y diatomeas, fueron dominantes. El ensamble algal mostró baja variación en cuanto a los índices comunitarios (diversidad, dominancia, riqueza), sin embargo se hallaron diferencias en las abundancias del ficoperifiton de cada una de las macrófitas evaluadas. También se encontraron diferencias en cuanto a la selectividad de sustrato de algunas especies tales como Closterium kuetzingii (Brébisson), Cocconeis placentula (Ehrenberg) y Hantzschia sp. (Ehrenberg), las cuales solo estuvieron presentes en las raíces de Eichhornia crassipes, a su vez Coelastrum sphaericum (Nägeli) solo se encontró en raíces de Pistia stratiotes. Se da el primer registro de la especie Ankistrodesmus fusiformis (Corda), para las ciénagas del departamento del Magdalena.
