“…An important benefit of this metric is the ability to incorporate changes in communities over a time series containing multiple time steps, to examine consistent trends in ordination space through time. Directionality has been used to examine community dynamics spatially and temporally, including as a response to environmental gradients in disturbances and anthropogenic change in forest communities (Fernandes Neto et al, 2019; Zald et al, 2020), stream fish (Mota‐Ferreira et al, 2021), and harmful algal blooms (Li et al, 2021).…”

Anthropogenic change has altered the composition and function of ecological communities across the globe (Kampichler et al., 2012;Magurran et al., 2010). While local biodiversity has not necessarily declined everywhere in response to such changes, species turnover is often higher than predicted by null models (Dornelas et al., 2014;Stegen et al., 2013;Vellend et al., 2017). Turnover in bird communities has been attributed to both climate and land cover change.Climate change in North America and Europe has led to both positive and negative impacts on bird populations as climate suitability changes throughout species ranges (Mason et al., 2019;

In a constantly changing environment brought about by the climate crisis and escalated anthropogenic perturbations driven by the growing population, harmful algal bloom dynamics and their impacts are expected to shift, necessitating adaptive management strategies and comprehensive research efforts. Similar to primary productivity, HABs have been thought to be driven primarily by major nutrients such as N, P, and Si. However, recent investigations on the role and importance of micronutrients as limiting factors in aquatic environments have been highlighted. This paper provides a review of metal and phytoplankton interactions, with a specific emphasis on pertinent information on the influence of trace nutrients on growth, toxin production, and other underlying mechanisms related to the dynamics of HABs. Low to near-depleted levels of essential nutrients, including Fe, Cu, Zn, Se, Mn, Co, and Mo, negatively impact cell growth and proliferation of various marine and freshwater HAB species. However, evidence shows that at elevated levels, these trace elements, along with other non-essential ones, could still cause toxic effects to certain HAB species manifested by decreased photosynthetic activities, oxidative stress, ultrastructure damage, and cyst formation. Interestingly, while elevated levels of these metals mostly result in increased toxin production, Co (i.e., yessotoxins, gymnodimine, and palytoxins) and Mn (i.e., isodomoic acid, okadaic and diol esters) enrichments revealed otherwise. In addition to toxin production, releasing dissolved organic matter (DOM), including dissolved organic carbon (DOC) and humic substances, was observed as an adaptation strategy, since these organic compounds have been proven to chelate metals in the water column, thereby reducing metal-induced toxicity. Whilst current research centers on free metal toxicity of specific essential elements such as Cu and Zn, a comprehensive account of how trace metals contribute to the growth, toxin production, and other metabolic processes under conditions reflective of in situ scenarios of HAB-prone areas would yield new perspectives on the roles of trace metals in HABs. With the growing demands of the global population for food security and sustainability, substantial pressure is exerted on the agriculture and aquaculture sector, highlighting the need for effective communication of information regarding the interactions of macro- and micronutrients with HABs to improve existing policies and practices.

“…It is also used in pyrotechnics as a blue-green colouring agent [13]. Copper is a compound of very high functional importance to aquatic plant microorganisms and is a substance with a relatively well-recognised effect and mechanism of action, e.g., [14][15][16][17]. Copper has an essential role in the metabolism of photosynthetic organisms and is a component of many proteins and enzymes involved in a number of metabolic pathways [18].…”

In this manuscript, we present the results of ecotoxicological tests conducted on the Baltic microphytobenthos community consisting largely of cosmopolitan species showing the responses at the community (taxonomic composition and structure), population (abundance), and cellular (chloroplast shape) levels. The tests were carried out for three chemicals with different modes of action on photosynthetic organisms, i.e., copper (II) chloride (at concentrations of 2·10−5 g·dm3 and 2·10−3 g·dm−3), glyphosate in the form of Roundup® (concentrations ranging from 4.2·10−2 to 8.5 g·dm−3), and the ionic liquid [BMIM]Cl (at concentrations of 1.13·10−3 g·dm−3 and 1.75·10−2 g·dm−3). The results of the study indicate that the responses of microphytobenthos at each level analysed are highly variable and difficult to predict a priori based on experiments performed on single strains. In addition, it was shown that microphytobenthic communities are relatively resistant to the substances tested, which is due to taxonomic richness and the resulting potential for substitution of sensitive taxa by more resistant taxa. The results obtained in the tests also indicate that the number of cells of individual taxa can remain at a similar level or increase over short periods of time despite the deformation of chloroplasts in a numerous group of cells.
