Ecology and evolution of competitive trait variation in natural phytoplankton communities under selection. [PDF]
Ecol Lett, 2022 Natural phytoplankton communities were subjected to three types of resource limitation (nitrogen, phosphorus, light) in outdoor mesocosms and 21 strains were isolated to quantify responses to selection of R* for these resources in the lab. R*s of phytoplankton can be good predictors of responses to resource limitation in natural communities, though ...

Naturally Occurring Microbiota Associated with Mosquito Breeding Habitats and Their Effects on Mosquito Larvae. [PDF]
Biomed Res Int, 2020 Immature mosquitoes are aquatic, and their distribution, abundance, and individual fitness in a particular breeding habitat are known to be dependent on mainly three factors: biotic factors, abiotic factors, and their interaction between each other and with other associated taxa.

The Desert in Bottles: The Culturable Microbiome of the Atacama Desert's Grit Crust. [PDF]
Environ Microbiol RepThe grit crust represents a unique biocrust type of the coastal Atacama Desert. Cyanobacteria, green algae and free‐living fungi were isolated along a fog gradient. Phylogenetic relationships indicated novel taxa and framed an indigenous microbiome. Microclimate and soil data support functional groups related to sites.

Light Influences the Growth, Pigment Synthesis, Photosynthesis Capacity, and Antioxidant Activities in <i>Scenedesmus falcatus</i>. [PDF]
Scientifica (Cairo)Light plays a significant role in microalgae cultivation, significantly influencing critical parameters, including biomass production, pigment content, and the accumulation of metabolic compounds. This study was intricately designed to optimize light intensities, explicitly targeting enhancing growth, pigmentation, and antioxidative properties in the ...

Naturally Occurring Microbiota in Dengue Vector Mosquito Breeding Habitats and Their Use as Diet Organisms by Developing Larvae in the Kandy District, Sri Lanka. [PDF]
Biomed Res Int, 2020 Naturally occurring microbiota in mosquito larval habitats are among biotic factors which affect the population dynamics of developing larvae. Many microbiota species serve as food items for vector mosquito larvae, and food limitations within habitats adversely affect larval survival, developmental rate, adult fitness, and thereby vector competence ...

Chlorella vulgaris as a food substitute: Applications and benefits in the food industry. [PDF]
J Food SciAbstract Chlorella vulgaris, a freshwater microalga, is gaining attention for its potential as a nutritious food source and dietary supplement. This review aims to provide a comprehensive discussion on C. vulgaris, evaluating its viability as a food substitute in the industry by exploring the nutritional value and application of C. vulgaris in the food

Ecology Letters, Volume 24, Issue 4, Page 761-771, April 2021., 2021 We tested predicted species biomass from monocultures against observations in two‐species mixtures. Although uptake rates were similar across species, following the classic Redfield ratio, we found that model accuracy was maximised around three to five resources, including resources such as Fe, Mg, Na and S, and that models that included only N and P ...

Atmospheric stilling offsets the benefits from reduced nutrient loading in a large shallow lake
Limnology and Oceanography, Volume 65, Issue 4, Page 717-731, April 2020., 2020 Abstract As part of a global phenomenon, a 30% decrease in average wind speed since 1996 in southern Estonia together with more frequent easterly winds resulted in 47% decrease in bottom shear stress in the large (270 km2), shallow (mean depth 2.8 m), and eutrophic Lake Võrtsjärv.

BioMed Research International, Volume 2020, Issue 1, 2020., 2020 A mosquito species has its own favourable requirements of abiotic and biotic characteristics including microbiota, in a breeding habitat. Some of the microbiota may cause parasitic or pathogenic effects to mosquito larvae such as species of viruses, parasitic bacteria, fungi, protists, entomopathogenic nematodes, and filamentous fungi.
