The role of light quality and species richness in shaping phytoplankton communities
Abstract In natural water bodies, the light spectrum changes with depth, often toward a higher proportion of blue light. While spectral niche partitioning and functional redundancy are important concepts, our understanding of how light spectrum changes affect phytoplankton communities is limited.

Identification of environmental factors affecting the abundance and distribution of phytoplanktons in Shamil Dam Lake [PDF]
Microscopic suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Studying the distribution of their population and understanding the interactions between environmental factors and the ...

A Study of Phytoplankton Dynamics in Lake Fayetteville as a Means of Assessing Water Quality [PDF]
Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow.

Biological activity in the wake of an island close to a coastal upwelling [PDF]
Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

On the fundamental additive modes of ocean color absorption
Abstract Previous principal component analyses of ocean color absorption coefficient spectra aλ$$ a\left(\lambda \right) $$ have shown the variation in these data is captured by a few eigenfunctions. Here, we perform an unsupervised, non‐negative matrix factorization (NMF) of aλ$$ a\left(\lambda \right) $$ to derive their fundamental and physically ...

Modelling the effect of vertical mixing on bottle incubations for determining in situ phytoplankton dynamics. I. Growth rates [PDF]
Reliable estimates of in situ phytoplankton growth rates are central to understanding the dynamics of aquatic ecosystems. A common approach for estimating in situ growth rates is to incubate natural phytoplankton assemblages in clear bottles at fixed ...

Abstract Anthropogenic salinization resulting from road salt application can degrade aquatic environments by altering the structure and function of phytoplankton communities, ultimately reducing flows of resources through aquatic food webs. However, physiological mechanisms underlying taxon‐specific responses to salinization are often poorly linked to ...

Introduction: Cascade hydropower development significantly alters the structure and function of river ecosystems. Phytoplankton, as primary producers, are highly sensitive to environmental changes, and their diversity and community structure reflect the ...

Phytoplankton Community Structure in Dardanelle Reservoir, Arkansas, 1975-1982 [PDF]
Phytoplankton data were collected with standard equipment and procedures over an eight-year period (1975-1982) in Dardanelle Reservoir, Arkansas. Community abundance and diversity at the genus level are described.

Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes
