Population dynamics: seasonal variation of phytoplankton functional groups in brazilian reservoirs (Billings and Guarapiranga, São Paulo) [PDF]
, 2009 A comunidade fitoplanctônica pode funcionar como sensor das variações do ambiente aquático respondendo rapidamente as essas alterações. Em sistemas aquáticos continentais é comum a coexistência de espécies que possuem as mesmas necessidades ecológicas e ...

Climate Shapes the Ratio Between Aboveground Plant Biovolume and Topsoil Macronutrients Worldwide
Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.ABSTRACT Soil nutrients are a major limiting factor for plant biomass, yet paradoxically, some of the most productive ecosystems thrive in nutrient‐poor soils. Here, we conducted a global field survey in 421 sites across all major biomes to investigate the environmental factors controlling the ratio between plant biovolume (a proxy for aboveground ...

Inferring phytoplankton carbon and eco-physiological rates from diel cycles of spectral particulate beam-attenuation coefficient [PDF]
, 2011 The diurnal fluctuations in solar irradiance impose a fundamental frequency on ocean biogeochemistry. Observations of the ocean carbon cycle at these frequencies are rare, but could be considerably expanded by measuring and interpreting the inherent ...

Rapid and versatile routine measurements of plankton biovolumes with BACCHUS [PDF]
Journal of Plankton Research, 1999 A semi-automated biovolume measurement application called BACCHUS (Biovolume Analysis Cum Calculus and High Utility Statistics), based on an image-analysis program combined with a database, was developed. With this application, biovolumes of plankton taxa can be determined while counting routine samples.

Quantitative Diatom Metabarcoding : A Correction Factor Inferred From Cell Biovolume
, 2017 DNA metabarcoding combined to high-throughput sequencing (HTS) is a promising approach for freshwater biomonitoring using benthic diatoms. This molecular approach is becoming faster, cheaper and allows handling more samples than the classical morphological one. rbcL gene has been proven suitable as a barcode for diatoms providing qualitatively relevant

Biovolume calculation for planktonic algae by using 3 dimensional models [PDF]
, 2019 Biovolume is one of the most important characteristics of planktic organisms which basically influences their functional properties like sinking velocity or tolerance to grazing. Biovolume calculation of microalgae is based on the determination of the geometrical shapes that approximate best the shape of the algal cells.

Comparison of Microphototrophic Communities Living in Different Soil Environments in the High Arctic
Frontiers in Ecology and Evolution, 2019 The Arctic region undergoes rapid climate change resulting in soil warming with consequent changes in microbial community structure. Therefore, it is important to gain more knowledge on the pioneer photosynthetic microorganisms and their relations to ...
