“…Below we discuss potential chemical controls; however, there are many uncertainties about the short, and long‐term impacts on biodiversity and ecosystem functioning (Humbert & Quiblier, 2019). These approaches are not completely selective and, as a consequence, can have significant negative effects on aquatic ecosystems through their impact to non‐target species (de Souza Beghelli, Pompêo, Rosa, & Carlos, 2016).…”

This review summarises knowledge on the ecology, toxin production, and impacts of toxic freshwater benthic cyanobacterial proliferations. It documents monitoring, management, and sampling strategies, and explores mitigation options. Toxic proliferations of freshwater benthic cyanobacteria (taxa that grow attached to substrates) occur in streams, rivers, lakes, and thermal and meltwater ponds, and have been reported in 19 countries. Anatoxin‐ and microcystin‐containing mats are most commonly reported (eight and 10 countries, respectively). Studies exploring factors that promote toxic benthic cyanobacterial proliferations are limited to a few species and habitats. There is a hierarchy of importance in environmental and biological factors that regulate proliferations with variables such as flow (rivers), fine sediment deposition, nutrients, associated microbes, and grazing identified as key drivers. Regulating factors differ among colonisation, expansion, and dispersal phases. New ‐omics‐based approaches are providing novel insights into the physiological attributes of benthic cyanobacteria and the role of associated microorganisms in facilitating their proliferation. Proliferations are commonly comprised of both toxic and non‐toxic strains, and the relative proportion of these is the key factor contributing to the overall toxin content of each mat. While these events are becoming more commonly reported globally, we currently lack standardised approaches to detect, monitor, and manage this emerging health issue. To solve these critical gaps, global collaborations are needed to facilitate the rapid transfer of knowledge and promote the development of standardised techniques that can be applied to diverse habitats and species, and ultimately lead to improved management.

“…Such a territorial approach should also permit the avoidance of the application of remedial methods to try to maintain some uses in aquatic ecosystems, regardless of the water quality (Humbert & Quiblier, 2019). For example, short-term solutions based on the application of chemicals (copper sulfates, hydrogen peroxide, etc.)…”

“…Knowing that cyanobacterial blooms are mainly due to eutrophication, the application of short-term solutions is frequently chosen by managers rather than sustainable solutions for the control of nutrient loads, which take time to have visible effects. Knowing also that there are many uncertainties about the environmental impacts of these short-term solutions and on their applications in the field, a territorial management approach to urban L&Ps should permit a better adequation between water quality and the uses that are required by these ecosystems (Humbert & Quiblier, 2019).…”

Urban lakes and ponds (L&Ps) provide numerous ecological and social services for local populations living in urban areas. Their monitoring and management are mostly based on water quality and ecological indicators and poorly consider public preferences and expectancies related to these artificial ecosystems. Even fewer studies bring together expert indicators and public expectations to inform management objectives for urban lakes. Based on an interdisciplinary study, this paper compares an expert assessment of the ecological quality of three urban L&Ps located in the Ile-de-France area with the public perception of these lakes. This approach permits us to explore the compatibilities and incongruences between the various ways in which scientists, managers and urban users assess urban L&P quality. Based on these data, we discuss how it could be possible to define management objectives that integrate quality indicators and expect these objectives to be used in a territorial approach that might allow to obtain a better adequacy between social users' expectations and the ecological status of these L&Ps.

“…Toxic cyanobacterial blooms lead to depleted oxygen and the release of many cyanotoxins into environments, which poses a serious threat to the biodiversity and stability of local aquatic ecosystems and further to human health [8,9]. As the frequency and duration of blooms continue to increase, it is essential to take measures to prevent and control their dramatic outbreaks [10][11][12]. Hence, a rapid and accurate method that enables the classification and monitoring of harmful algal blooms (HABs) is increasingly desired in water environment management [13].…”

Harmful algal blooms (HABs) pose a global threat to the biodiversity and stability of local aquatic ecosystems. Rapid and accurate classification of microalgae and cyanobacteria in water is increasingly desired for monitoring complex water environments. In this paper, we propose a pulse feature-enhanced classification (PFEC) method as a potential solution. Equipped with a rapid measurement prototype that simultaneously detects polarized light scattering and fluorescence signals of individual particles, PFEC allows for the extraction of 38 pulse features to improve the classification accuracy of microalgae, cyanobacteria, and other suspended particulate matter (SPM) to 89.03%. Compared with microscopic observation, PFEC reveals three phyla proportions in aquaculture samples with an average error of less than 14%. In this paper, PFEC is found to be more accurate than the pulse-average classification method, which is interpreted as pulse features carrying more detailed information about particles. The high consistency of the dominant and common species between PFEC and microscopy in all field samples also demonstrates the flexibility and robustness of the former. Moreover, the high Pearson correlation coefficient accounting for 0.958 between the cyanobacterial proportion obtained by PFEC and the cyanobacterial density given by microscopy implies that PFEC serves as a promising early warning tool for cyanobacterial blooms. The results of this work suggest that PFEC holds great potential for the rapid and accurate classification of microalgae and cyanobacteria in aquatic environment monitoring.
