Seasonal changes in optical properties of two contrasting tropical freshwater systems
We investigated how allochthonous and autochthonous sources of dissolved organic matter (DOM) affected the optical conditions and chemical characteristics of two contrasting tropical freshwaterExpand

Seasonal Changes in Metabolic Rates of Two Tropical Lakes in the Atlantic Forest of Brazil
Abstract We studied the importance of environmental drivers for the seasonal dynamics of gross primary production (GPP), ecosystem respiration (R), and net ecosystem production in surface waters ofExpand

Partitioning of the diffuse attenuation coefficient for photosynthetically available irradiance in a deep dendritic tropical lake.
We studied the effects of particulate and dissolved optically active components on the attenuation of photosynthetic active radiation (PAR) in a tropical lake. The temporal and spatial distributionExpand

Fluctuations of the population of Daphnia laevis Birge 1878: a six-year study in a tropical lake.
The fluctuation of the population of Daphnia laevis in Lake Jacaré (Middle River Doce, Minas Gerais) was monitored monthly (at one point in the limnetic region) for six years (2002-2007) as part ofExpand

Distinctive effects of allochthonous and autochthonous organic matter on CDOM spectra in a tropical lake
Abstract. 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 onExpand

Linking shifts in bacterial community with changes in dissolved organic matter pool in a tropical lake.
Bacterioplankton communities have a pivotal role in the global carbon cycle. Still the interaction between microbial community and dissolved organic matter (DOM) in freshwater ecosystems remainsExpand

Seasonal dynamics of Daphnia laevis Birge, 1878 ephippia in a tropical lake with a description of a new methodology for in situ evaluation.
The effect of dormancy in zooplankton populations is still unknown, largely because of the lack of methods to estimate hatching and production of the dormant stages. This study aimed to compare theExpand

Occurrence of Kellicottia bostoniensis (Rousselet, 1908) and Mesocyclops ogunnus Onabamiro, 1957 in lakes of the Middle River Doce, MG, Brazil
The presence of the two exotic zooplankton species (Kellicottia bostoniensis and Mesocyclops ogunnus) in lakes of the Middle River Doce is discussed in the present work. K. bostoniensis wasExpand

Effects of nutrients and organic matter inputs in the gases CO2 and O2: A mesocosm study in a tropical lake
Abstract Lakes are important components in the carbon cycling and threatened by direct and indirect human activities, which ultimately affect metabolic processes. We analyzed the daily dynamics ofExpand
