Considerations regarding the dominance of Cylindrospermopsis raciborskii under low light availability in a low phosphorus lake

Autor: Denise Tonetta, Mariana Coutinho Hennemann, Débora Monteiro Brentano, Mauricio Mello Petrucio

Publikováno v: Acta Botânica Brasílica, Vol 29, Iss 3, Pp 448-451 (2015)

ABSTRACTAlthough many studies have shown that the dispersion, increased abundance and dominance of cyanobacteria can be attributed to nutrient enrichment, we discuss features contributing to the dominance of Cylindrospermopsis raciborskii in a shallo

Seasonal changes in primary production and respiration in a subtropical lake undergoing eutrophication

Autor: Denise Tonetta, Mauricio Mello Petrucio

Publikováno v: Tonetta, D & Petrucio, M 2020, ' Seasonal changes in primary production and respiration in a subtropical lake undergoing eutrophication ', Environmental Monitoring and Assessment, vol. 192, 565 . https://doi.org/10.1007/s10661-020-08525-6

The balance between gross primary production (GPP) and respiration (R) is frequently used to estimate the role of lakes in the carbon cycle. Seasonal changes in the carbon cycle of subtropical lakes are often underestimated, but changes in meteorolog

Biogeosciences, Vol 15, Pp 2931-2943 (2018)

Despite the increasing understanding about differences in carbon cycling between temperate and tropical freshwater systems, our knowledge on the importance of organic matter (OM) pools on light absorption properties in tropical lakes is very scarce.
