Mytilus edulis chilensis infested with Coccomyxa parasitica (Chlorococcales, Coccomyxaceae) [PDF]

Journal of Molluscan Studies, 1999
The association between the green alga Coccomyxa parasitica (Chlorococcales) and the mussel Mytilus edulis chilensis at Goose Green, Falkland Islands is reported. C. parasitica occurred within the soft tissues with an overall infestation rate of 16%. The highest levels of infestation (23%) occurred in individuals from the middle of the main mussel bed,

Inorganic carbon promotes photosynthesis, growth, and maximum biomass of phytoplankton in eutrophic water bodies

Freshwater Biology, Volume 64, Issue 11, Page 1956-1970, November 2019., 2019
Abstract The traditional perception in limnology has been that phytoplankton biomass in lakes is limited by phosphorus, nitrogen, and light, but not by dissolved inorganic carbon (DIC) because CO2 can be supplied from the atmosphere. We tested the possibility of carbon limitation of photosynthesis, growth, and biomass accumulation of phytoplankton ...

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Species interactions mediate thermal evolution

Evolutionary Applications, Volume 12, Issue 7, Page 1463-1474, August 2019., 2019
Abstract Understanding whether populations and communities can evolve fast enough to keep up with ongoing climate change is one of the most pressing issues in biology today. A growing number of studies have documented rapid evolutionary responses to warming, suggesting that populations may be able to persist despite temperature increases. The challenge

Phytoplankton from Duas Bocas Reservoir, Espírito Santo State, Brazil (except diatoms)

Hoehnea
Duas Bocas is a small water supply reservoir (0.51 km²) located in a forested area (Duas Bocas Biological Reserve) (20º18'S and 40º28'W). Phytoplankton community was investigated by samplings weekly taken in the dry (July, 1998) and rainy (March 1999 ...

Impacts of counting protocols for light microscopy on estimates of biodiversity and algal density of phytoplankton

Limnology and Oceanography: Methods, Volume 22, Issue 12, Page 930-942, December 2024.
Abstract Knowledge on the biodiversity and abundance of phytoplankton is key for many ecological and societal (e.g., blue growth) questions. Gathering temporal variation and spatial patterns on key indicators requires reliable and standardized protocols on sampling, species identification and counting.

Seston Fatty Acid Responses to Physicochemical Changes in Subalpine Lake Lunz, Austria

Water Resources Research, Volume 54, Issue 10, Page 8442-8455, October 2018., 2018
Abstract Rapid increase in lake temperature can cause a shift toward the dominance of warm temperature tolerant species, including Cyanobacteria that are deficient in polyunsaturated fatty acids (PUFA) supporting consumer growth and reproduction. To increase our understanding of how changes in physicochemical lake parameters affect phytoplankton ...
