Maternal Trophic Status and Offpsring Phenotype in a Marine Invertebrate. [PDF]

Sci Rep, 2018
AbstractOffspring size variation in relation to maternal size and season is characteristic of a range of species living in seasonal environments. Little is known about the proximate mechanisms explaining the links between maternally driven variation in offspring phenotypes, for instance when mothers have different diets depending on their size or the ...

Effect of Environmental Heterogeneity and Trophic Status in Sampling Strategy on Estimation of Small-Scale Regional Biodiversity of Microorganisms [PDF]

Microorganisms, 2022
Microorganisms are diverse and play key roles in lake ecosystems, therefore, a robust estimation of their biodiversity and community structure is crucial for determining their ecological roles in lakes. Conventionally, molecular surveys of microorganisms

Knowledge mining for the differentiation pattern with respect to the productivity and trophic status of some selected lakes of Western Himalayas

Frontiers in Environmental Science, 2023
The present study deals with an account of the primary productivity and trophic status of Rewalsar, Kuntbhyog, and Prashar lakes of Western Himalayas. Seasonal variations in gross primary productivity (GPP) (g C m–2 day–1), net primary productivity (NPP,

Zooplankton and trophic status of Peipsi-Pihkva Lake [PDF]

Трансформация экосистем, 2018
Long-term studies of the zooplankton of Chudsko-Pskovskoe (Peipsi-Pihkva) Lake have shown that the species composition and structure of the community correspond to those of eutrophic waters. Intensification of the eutrophication of the lake in the period

A summer in the greater Paris: trophic status of peri-urban lakes shapes prokaryotic community structure and functional potential [PDF]

Environmental Microbiome
With more than 12 million inhabitants, the Greater Paris offers a “natural laboratory” to explore the effects of eutrophication on freshwater lake’s microbiomes within a relative restricted area (~ 70 km radius).

Illumina sequencing-based analysis of sediment bacteria community in different trophic status freshwater lakes. [PDF]

Microbiologyopen, 2017
Sediment bacterial community is the main driving force for nutrient cycling and energy transfer in aquatic ecosystem. A thorough understanding of the community's spatiotemporal variation is critical for us to understand the mechanisms of cycling and ...
