This review highlights the presence and ecological roles of fungi in lakes, and aims to stim- ulate research in aquatic mycology. In the study of lentic systems, this field is an almost completely neglected topic and, if considered at all, has often been restricted to specific groups of fungi, such as yeasts, filamentous fungi (e.g. aquatic hyphomycetes), or phycomycetes (an obsolete taxonomic category that included various fungal and fungal-like organisms). We document that aquatic fungi are… Expand

Figures and Tables from this paper

Aquatic Fungi: A Disregarded Trophic Level in Ecological Risk Assessment of Organic Fungicides
TLDR
Important functions of freshwater fungi are described, an overview of adverse effect levels of fungicides on this organism group is provided, and the fungal community of freshwater ecosystems is proposed to integrate as an additional trophic level in the current fungicide risk assessment frameworks. Expand
Importance of Saprotrophic Freshwater Fungi for Pollen Degradation
TLDR
The decomposer niche overlap of saprotrophic fungi and bacteria was studied on pollen by performing microcosm experiments with three different lake types to highlight the fact that carbon-to-nitrogen ratios may also control fungal contributions to OM decomposition in aquatic ecosystems. Expand
Fungal communities in Scandinavian lakes along a longitudinal gradient
TLDR
The results indicate that surface waters of oligotrophic lakes harbour a diverse pool of fungi, both with tentative terrestrial and true aquatic origin, and longitude and environmental factors were important in structuring the fungal community composition. Expand
Community Structure of Planktonic Fungi and the Impact of Parasitic Chytrids on Phytoplankton in Lake Inba, Japan
TLDR
This study examines the temporal fluctuations of freshwater fungi, including chytrids, in Lake Inba by using molecular techniques of denaturing gradient gel electrophoresis (DGGE), and is the first study to show that DGGE is a useful preliminary approach for examining the diversity of planktonic fungi including chYtrids. Expand
Effect of trophic status in lakes on fungal species diversity and abundance.
TLDR
It is illustrated that the species diversity and abundance of fungi in limnic waters depend on the concentration of organic matter, chlorophyll a concentration, and the degree of water pollution. Expand
Novel basal, fungal lineages from freshwater phytoplankton and lake samples.
TLDR
A method to genetically analyse fungi directly from single, infected colonies of the phytoplanktonic host was applied to field samples of large diatom species from mesotrophic Lake Biwa and eutrophic Lake Inba, Japan, and revealed that fungi attached to large diatoms included not only members of Chytridiomycota, but also members of Aphelida, CryptomyCota and yeast. Expand
What lies beneath? Fungal diversity at the bottom of Lake Michigan and Lake Superior.
TLDR
The first comprehensive survey of fungi from sediment from Lake Michigan and Lake Superior, resulting in 465 fungal taxa with only 7% of sequence overlap between these two methods, suggests an immense amount of fungal diversity remains to be studied in these aquatic fungal communities. Expand
Fungi in aquatic ecosystems
TLDR
This Review conceptualizes the spatiotemporal dimensions, diversity, functions and organismic interactions of fungi in structuring aquatic food webs and focuses on currently unexplored aquatic fungal diversity, highlighting poorly understood ecosystems, including emerging artificial aquatic habitats. Expand
High habitat-specificity in fungal communities of an oligo-mesotrophic, temperate lake
TLDR
This study provides a first estimate of lake-wide fungal diversity and highlights the important contribution of habitat-specificity to totalFungal diversity. Expand
Temporal variation in community structure of zoosporic fungi in Lake Biwa, Japan
Zoosporic fungi play an important role in aquatic environments, but their diversity, especially that of parasitic fungi of phytoplankton, has still not been fully revealed. We conducted monthlyExpand

Role of fungi in freshwater ecosystems
TLDR
There are more than 600 species of freshwater fungi with a greater number known from temperate, as compared to tropical, regions and their distribution probably follows that of Ingoldian fungi, which are either cosmopolitan, restricted to pantemperate or pantropical regions, or in a few cases, have a restricted distribution.

Established and potential impacts of eukaryotic mycelial decomposers in marine/terrestrial ecotones
TLDR
It appears that major types of marine ecotones differ sharply in the balance among major groups of decomposers (eumycotes, oomycote, and bacteria) with regard to their utilization of vascular-plant litter. Expand
Effects of arbuscular mycorrhizae on biomass and nutrients in the aquatic plant Littorella uniflora
TLDR
The study proved that the symbiosis between AMF and L. uniflora had a positive impact on the retention of N and P in the plants at very low nutrient concentrations in the water and on biomass development. Expand
The ecology of chytrids in aquatic ecosystems: roles in food web dynamics
TLDR
New molecular methods for analysis of chytrid diversity in aquatic environments have the potential to provide accurate quantitative data necessary for better understanding of ecological processes in aquatic ecosystems. Expand
Aquatic Actinomycete-Fungal Interactions and Their Effects on Organic Matter Decomposition: A Microcosm Study
TLDR
It is demonstrated that actinomycete-fungal interactions and their colonization dynamics affect the accumulation of biomass, extracellular enzyme activities, and rates of organic matter decomposition. Expand

TLDR
The role of arbuscular mycorrhizal fungi in carbon and nutrient cycling in forest ecosystems and the role of bacteria and fungi in polycyclic aromatic hydrocarbon biodegradation and remediation of contaminated soils is examined. Expand
Daphnia can protect diatoms from fungal parasitism
TLDR
Daphnia can affect the seasonal succession of chytrids and their host phytoplankton species and implies that zoospore-producing fungi may play an ecological role as food sources for Daphnia in aquatic food webs. Expand
Freshwater and marine lichen-forming fungi
Lichen-forming fungi can occur on river and lake margins subjected to varying water levels, and on tidal coastal rocks where they can constitute major components of the biota. There are approximatelyExpand
Dynamics of Bacterial and Fungal Communities on Decaying Salt Marsh Grass
TLDR
The bacterial and fungal assemblages associated with two decomposition stages of Spartina alterniflora detritus in a productive southeastern U.S. salt marsh indicated that the salt marsh saprophyte communities have little-to-moderate variability spatially or with decomposition stage, but considerable variability temporally.

Antagonism between Bacteria and Fungi on Decomposing Aquatic Plant Litter
TLDR
It is suggested that the antagonism between bacteria and fungi is an important controlling factor for microbial colonization and growth on aquatic plant litter. Expand
