“…Further, the xenobiotics in sediments can be toxic to the zooplankton community organisms (Gillis et al 2006;Terra & Gonçalves 2013). Studies carried out with dormant forms have shown considerable resistance of eggs to pollutants, corroborating the importance of egg banks in the repopulation of the water column after periods of environmental stress (Oskina et al 2018;Zadereev et al 2019).…”

“…This refractory period benefits the population temporarily if the first individuals to hatch are unsuccessful (De Meester et al 1998). Therefore, the passive community is fundamental for the diversification of the active community and the repopulation of the water column after periods of environmental stress (Hairston 1996;Zadereev et al 2019). It can also be used as a bioindicator of changes in the water column (Weider et al 1997).…”

Small water bodies host numerous zooplankton species, which are directly influenced by their surroundings. During environmental instability, zooplanktons produce nutrient-rich eggs, via the process of diapause, that sink to the sediment and remain dormant under unfavorable environmental conditions. We aimed to observe how diapause helps maintain the richness of the zooplankton community in the small-sized Amália Reservoir, located in the municipality of Alfenas, Minas Gerais, Brazil. The studied reservoir is a well-defined microbasin with urbanization processes and a predominance of pastures and coffee plantations. The reservoir has low zooplanktonic richness despite having numerous macrophytes on its margin, which contributes to species richness. Zooplankton species were observed in dormant forms that were not recorded in the water column, demonstrating the importance of egg banks for long-term zooplanktonic survival. However, anthropogenic activities may have influenced the low number of species and dormant forms. Thus, knowing the species present in the water column in the sediment of the Amália Reservoir proved the importance of the dormant form bank for the long-term survival and structuring of the community.

“…However, their capacity to survive chemical stress events has been less studied (Arenas‐Sanchez et al, 2016). Vandekerkhove et al (2013) showed an extreme tolerance of ostracod eggs to a variety of stressors, including insecticides; and Zadereev et al (2019) also found a high tolerance of cladoceran resting eggs to toxic substances. On the other hand, Navis et al (2013) found that some pesticides can affect hatching rates of dormant eggs of Daphnia magna , as well as the survival and performance of the hatched individuals (either affecting embryos or hatchlings), thus having implications for the evolutionary potential of a population.…”

Recovery, recolonization, and adaptation in a chemical stress context are processes that regenerate local populations and communities as well as the functions these communities perform. Recolonization, either by species previously present or by new species able to occupy the niches left empty, refers to a metacommunity process with stressed ecosystems benefiting from the dispersal of organisms from other areas. A potential consequence of recolonization is a limited capacity of local populations to adapt to potentially repeating events of chemical stress exposure when their niches have been effectively occupied by the new colonizers or by new genetic lineages of the taxa previously present. Recovery, instead, is an internal process occurring within stressed ecosystems. More specifically, the impact of a stressor on a community benefits less sensitive individuals of a local population as well as less sensitive taxa within a community. Finally, adaptation refers to phenotypic and, sometimes, genetic changes at the individual and population levels, allowing the permanence of individuals of previously existing taxa without necessarily changing the community taxonomic composition (i.e., not replacing sensitive species). Because these processes are usually operating in parallel in nature, though at different degrees, it seems relevant to try to understand their relative importance for the regeneration of community structure and ecosystem functioning after chemical exposure. In the present critical perspective, we employed case studies supporting our understanding of the underlying processes with the hope to provide a theoretical framework to disentangle the relevance of the three processes for the regeneration of a biological community after chemical exposure. Finally, we provide some recommendations to experimentally compare their relative importance so that the net effects of these processes can be used to parameterize risk‐assessment models and inform ecosystem management.

“…[9]. The reduced level of metabolism underlying biological dormancy causes nonspecific resistance of resting stages to toxic substances often found in ballast waters [10]. This is what determines the high efficiency of transportation of aquatic invertebrates by ship ballast waters, particularly in water bodies of temperate climates [11].…”

Invasive and Rare Aquatic Invertebrates of Taiwan with a Focus on Their Dormancy

Invertebrates in tropical ecosystems are generally considered to have little or no need for a dormant phase due to the stability of the habitat. However, resting stages of aquatic organisms are occasionally found here as well. This fact increases the possibility of transport of tropical organisms by ships’ ballast water, which is the main vector for the spread of alien aquatic organisms between continents. During a study of resting stages in the bottom sediments of the island of Taiwan in 2006–2007, nine species of invertebrates were found, invasive or new to the fauna of the island, with some of them forming large banks of resting stages in sediments.
