The impact of physical processes on algal growth [PDF]

open access: yes, 1992
Mixing and transport processes in surface waters strongly influence the structure of aquatic ecosystems. The impact of mixing on algal growth is species-dependent, affecting the competition among species and acting as a selective factor for the ...

Benthic macroalgae of Shark Bay, Western Australia [PDF]

open access: yes, 1990
One hundred and sixty one taxa of benthic macro-algae are reported from Shark Bay, Western Australia, growing either on subtidal rock platforms, on the extensive sandflats that dominate the bay, or as epiphytes on seagrasses and other algae.

Microbial communities and functional diversity in seafood

open access: yesJSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Factors Controlling Changes in Epilithic Algal Biomass in the Mountain Streams of Subtropical Taiwan.

open access: yesPLoS ONE, 2016
In upstream reaches, epilithic algae are one of the major primary producers and their biomass may alter the energy flow of food webs in stream ecosystems. However, the overgrowth of epilithic algae may deteriorate water quality.

The production of algae growing on gravel in a chalk-stream [PDF]

open access: yes, 1976
Epilithic algae, ie that growing on the surface of stones, was studied as part of the work on the energy flow of the chalk-stream ecosystem, by the River Laboratory. The study area was on Bere Stream and 2 neighbouring streams.

Production of the freshwater microalgae Scenedesmus dimorphus and Arthrospira platensis by using cattle digestate [PDF]

open access: yes, 2014
Microalgae are considered one of the most promising feedstocks for biofuels; these microorganisms are also able to enhance the nutritional content of conventional food preparations, or can be converted into other fuel products, such as hydrogen, ethanol,

Red, green, blue color indices as proxy for Symbiodiniaceae cell density and chlorophyll content during coral bleaching

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Coral bleaching, the breakdown of the symbiosis between the coral host and endosymbiotic microalgae, is the main cause of widespread coral reef degradation. Current visual assessment methods for coral health, including color reference cards, are constrained by subjective human color perception and limited resolution.

Long-term changes of the crustacean zooplankton community in Lake Mjøsa, the largest lake in Norway

open access: yesJournal of Limnology, 2003
Lake Mjøsa has been subject to an accelerating eutrophication from the 1950s to the mid 1970s, but comprehensive nutrient reduction efforts caused marked reductions of phytoplankton production and biomass during the 1980s, a process that continued during
