Rethinking the lake trophic state index [PDF]

open access: yesPeerJ, 2019
Lake trophic state classifications provide information about the condition of lentic ecosystems and are indicative of both ecosystem services (e.g., clean water, recreational opportunities, and aesthetics) and disservices (e.g., cyanobacteria blooms ...

Assessment of the trophic state of the Soła River dam cascade, Polish Carpathians: a comparison of the methodology [PDF]

open access: yesScientific Reports, 2023
The aim of this research was to determine the trophic state of mountain dam reservoirs, which are characterized by greater hydrological and ecological dynamics than lowland reservoirs.

Resilience to changes in lake trophic state: Nutrient allocation into Daphnia resting eggs [PDF]

open access: yesEcology and Evolution, 2019
During past decades, many lakes underwent drastic human‐caused changes in trophic state with strong implications for population dynamics and food web processes.

Modeling lake trophic state: a random forest approach [PDF]

open access: yesEcosphere, 2016
Productivity of lentic ecosystems is well studied, and it is widely accepted that as nutrient inputs increase, productivity increases and lakes transition from lower trophic state (e.g., oligotrophic) to higher trophic states (e.g., eutrophic).

Phytoplankton alpha diversity indices response the trophic state variation in hydrologically connected aquatic habitats in the Harbin Section of the Songhua River [PDF]

open access: yesScientific Reports, 2020
The relationship between biodiversity and ecological functioning is a central issue in freshwater ecology, but how this relationship is influenced by hydrological connectivity stress is still unknown.

Trophic state assessment of optically diverse lakes using Sentinel-3-derived trophic level index

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
An accurate estimation of trophic state of lakes with satellite remote sensing is a challenge due to the optical complexity and variability associated with inland waters. Match-up data from 393 sampling stations that has concurrent Sentinel-3 OLCI images

Composition of epilithic diatom and soft-algal assemblages in infralittoral zones of Tennessee reservoirs and correlations of composition to trophic state

open access: yesJournal of Freshwater Ecology, 2023
Assemblages of infralittoral periphytic algae are understudied due partially to the historical emphasis on phytoplankton and other water-column characteristics to evaluate the integrity of lentic systems.

Zooplankton Communities as Bioindicators in Zaghen Restored Wetland, Danube Delta Biosphere Reserve [PDF]

open access: yesScientific Annals of the Danube Delta Institute, 2019
Eutrophication is a process characterized by an increase in the aquatic system productivity, which causes profound changes in the structure of its communities.

Trophic state footprint index model and its application to Dianchi Lake, China

open access: yesEcological Indicators, 2021
Given ongoing changes in regional climate and hydrologic conditions, a vast of studies have reported that under-prediction or over-prediction of the trophic status of a water body was widely existing by classic trophic state index method, it would create

Trophic assessment of four tropical reservoirs using phytoplankton genera

open access: yesActa Limnologica Brasiliensia, 2022
: Aim Monitoring the trophic state of reservoirs requires indices that provide a quick report of the ecosystem to decision makers. This study aimed to develop a system of trophic status indicators for tropical mountain reservoirs using phytoplankton ...
