The role of light quality and species richness in shaping phytoplankton communities

Limnology and Oceanography, EarlyView.
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.

On the fundamental additive modes of ocean color absorption

Limnology and Oceanography, EarlyView.
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 ...

Tradeoffs between elemental homeostasis and growth govern freshwater phytoplankton responses to salinization

Limnology and Oceanography, EarlyView.
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 ...

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

Limnology and Oceanography, EarlyView.
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

Understanding stoichiometric adjustments in a freshwater plant: Responses to sediment and water nutrient dynamics across lake trophic gradients

Limnology and Oceanography, EarlyView.
Abstract Despite ongoing efforts to reduce nutrient inputs, eutrophication continues to disrupt biogeochemical cycles and destabilize freshwater food webs. In this study, we examine the stoichiometric responses of the freshwater plant Myriophyllum spicatum under varied environmental conditions across lakes of differing trophic status.

Disentangling the effects of climate change in a mountain lake through community structure analysis

Limnology and Oceanography, EarlyView.
Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...

Microbial colonization and function of biofilms developing on plastics and bioplastics in a pristine mountain stream ecosystem

Limnology and Oceanography, EarlyView.
Abstract Streams naturally receive allochthonous particulate organic materials, but human activity may contribute additional plastic litter inputs, which can affect ecosystem functioning. Our objective was to assess the effect of plastic and bioplastic inputs on microbial biomass and function in a pristine mountain stream.

Inundation of different river bank heights influences organic matter concentrations and zooplankton abundance

Limnology and Oceanography, EarlyView.
Abstract Regulation and water extraction change flow regimes in lowland rivers, affecting ecosystem functions and wetting patterns of riverbanks. River connectivity to lateral environments is crucial for organic matter cycling and the life cycles of diapausing microinvertebrates. While extreme hydraulic periods (floods and cease‐flow) are well‐studied,
