Última Limnological characteristics and seasonal changes in density and diversity of the phytoplanktonic community at the Caçó pond, Maranhão State, Brazil BABT Dellamano-Oliveira,Maria José; Senna,Pedro Américo Cabral; Taniguchi,Glória Massae. Seasonal changes of the phytoplanktonic community and limnological abiotic characteristics of Caçó pond (Maranhão State, Brazil) was evaluated from two field researches during the rainy (April 1999) and dry (November 1999) seasons. Measurements of twelve chemical and physical variables and phytoplankton collections were carried out at eight sampling stations. The Chlorophyceae and Cyanobacteria groups were in highest fractions during the rainy and dry seasons, respectively. The limnological abiotic variables showed a homogenous spatial distribution. The cluster analysis, using Bray-Curtis distance, distinguished two major groups, represented by the most common and abundant species in both the periods. The results showed that the climate regime, due to the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Seasonality; Phytoplankton; Diversity; Tropical region.

The present study aimed to analyse the abiotic characteristics spatial variability in the littoral-limnetic gradient of the Diogo Pond, Mogi-Guaçu River floodplain, as well as evaluating the hydrological influence on the spatial gradient. During the hydrological cycle, four field trips (high water, flood, low water, and drought) were carried out at three sampling stations: littoral, interface, and limnetic region. Analysis of physical and chemical variables allowed to conclude that the time scale established by the hydrological cycle was the main forcing function over the limnological variability of the Diogo Pond. The relative spatial scale related to littoral-limnetic gradient contributed secondarily to the abiotic variability. Littoral was characterized...
