“…As taxas de acumulação de biomassa foram calculadas como sendo a diferença entre o teor de clorofila-a entre dois estádios consecutivos dividida pelo intervalo de tempo considerado em dias (Sládecek & Sládecková 1964). Para análise taxonômica, o material perifítico foi removido das lâminas e fixado em formalina a 4%.…”

-(Periphytic algal community succession in a tropical oligotrophic reservoir (São Paulo, Brazil): comparison between dry and rainy periods). This study aimed at evaluating the time scale influence (successional and seasonal) on the periphyton biomass, diversity, and algal community structure in a tropical oligotrophic reservoir, southeast Brazil. Succession process was followed during dry and rainy periods by every 3-day samplings over 27 days, and included 16 abiotic variables and periphyton properties on artificial substrate. Chlorophyll-a values were low and similar between periods, however, with the highest loss rates observed during the rainy season. Shannon diversity was high (3.4-4.5 bits ind -1 ) and relatively stable among periods and along the entire succession. Chlorophyceae was the most abundant class over succession, mainly represented by Chlamydomonas planctogloea Skuja that contributed with 23% (dry) and 37% (rainy) of the mean total density. Integrated analysis of species and environmental variables revealed climatic period as the main driving force on periphyton structure. Oocystis lacustris Chodat and Gymnodinium sp. were associated with dry period and lower temperature and ammonium values, as well as with higher pH, dissolved oxygen, and total phosphorus levels. Frustulia rhomboides (Ehr.) de Toni var. rhomboides and Cosmarium majae Strom were associated with rainy season and, inversely, to the dry season abiotic variables. Periphyton community was mainly controlled by the climatic period, the autogenic succession being of less importance. Photosynthetic biomass accrual process and periphytic algal species assemblages were more sensitive to such variation. Present results contribute to a better understanding of the periphyton community structuring in oligotrophic reservoirs, providing a reference for changes in degraded tropical systems.

“…and Sladeckova (1962) discussed periphyton terminology. Several reviews of methodology are also available (Lund and Talling 1957, Sladeckova 1962, Sladecek and Sladeckova 1964. Current recommended methods for periphyton collection are detailed by Weber (1973).…”

“…He realized that the ash-free dry weight of periphyton was an estimate of net primary production. Sladecek and Sladeckova (1964) reviewed the different methods used for the analysis of production on artificial sub~ strate. The instantaneous biomass accumulation method (Kevern, et al 1966) provided a refinement of production estimates in that only the acceleration phase of periphyton growth is considered.…”

“…Naumann (1915) and Hentschel (1916) were among the first to study Aufwuchs using glass slides to avoid problems associated with natural substrates. In the ensuing years glass slides and other artificial substrates have been used to assess water pollution and study aspects of biomass accumulation in natural stream ecosystems (Butcher, 1932 ;Castenholz, 1960;Sladecek & Sladeckova, 1964 ;King & Ball, 1966;Cattaneo et al, 1975) . To further isolate ecological factors influencing Aufwuchs growth, many workers as well as this study have used experimental stream ecosystems in which selected variables including light, current, temperature, and toxicants may be controlled (McIntire et al, 1964 ;Warren & Davis, 1971 ;McIntire,1975 ;Rodgers, 1977) .…”

The influence of ecosystem depopulation on the Aufwuchs accumulation process was studied in experimental stream ecosystems during fall, spring, and summer 1977-78 . Aufwuchs biomass (chlorophyll a, ATP, and ash-free dry weight) accumulated slower in the depopulated streams than in the reference streams. The influence of depopulation on Aufwuchs accumulation in spring and summer disappeared in less than two weeks suggesting how rapidly stream Aufwuchs may recover from short-term catastrophes . Variability among replicate ATP measurements was less after one or two days of accumulation than after longer accumulation times.
