“…Temperature is probably the main factor that affects body size of organisms in general, including microcrustaceans (Kappes and Sinsch 2002;Engert et al 2013). Several laboratory experiments have demonstrated that both cladocerans and copepods achieve smaller body sizes and individual biomass at higher temperatures (Moore and Folt 1993).…”

“…The magnitude of such responses to temperature vary among species, and even on genetic lineages within the same species (Bruijing et al 2018). Other factors interact with temperature to determine body size (Sebastian et al 2012), such as presence of predators (Kappes and Sinsch 2002), chemical stress (Engert et al 2013), and food concentration (Ban 1994), but usually with weaker effects.…”

“…Other kinds of stress lead to different effects. Mild stress by dissolved organic carbon (as humic substances) increases resistance to salt stress and has beneficious effects on body growth and life-history traits (Engert et al 2013;Suhett et al 2011). Pharmaceuticals are an increasing stress in freshwaters, but their effects on zooplankton are still largely unknown (Sarma et al 2017).…”

Functional traits are ecologically relevant characteristics of species. They are relevant to community structuring in face of environmental drivers (response traits) and to ecosystem processes (effect traits). For planktonic microcrustaceans, the link between functional traits and their responses or effects is not always clear. Our objective was to review the literature on linking functional traits to environmental drivers and ecosystem processes for planktonic cladocerans and copepods. Response traits are discussed in four categories: morphological, life history, behavioral, or physiological. Temperature, predation, resources, and stressors are important drivers of morphological and life-history traits. Body size, a morphological trait, is probably the most important trait, because it responds to several environmental characteristics and is correlated with physiological traits and to zooplankton impact on ecosystems functions. In an ecosystem perspective, zooplankton is an important energy link between primary producers and secondary consumers. In trophic webs, it may control phytoplankton biomass and productivity, with consequences for whole lakes. Its influence on carbon, nitrogen, and phosphorus cycles is expected to increase with body size. Other traits may be important, but there is a lack of information. We point out the need of more functional trait research, especially with freshwater copepods and neglected tropical species. For a better understanding of natural systems, an integrative approach of multiple traits with multiple environmental drivers and ecosystem functions is necessary.

“…For this reason, the application of such direct methods for cladocerans is not much worthy due to sensitivity problems. However, one integrative method for evaluating the total oxygen scavenging capacity (TOSC) of samples-i.e., their global oxidants/anti-oxidants balance-has been successfully applied for Daphnia magna and even to the smaller Moina macrocopa exposed to natural chemicals (Steinberg et al, 2010a;Hofmann et al, 2012;Engert et al, 2013). This approach seems more informative and relevant for understanding the effects of stress in organisms than measuring single oxidant species or antioxidant enzymes (Steinberg et al, 2010a), and it could be further applied to cladocerans in other ecological contexts.…”

An overview of the contribution of studies with cladocerans to environmental stress research

Cladocerans are microcrustaceans component of the zooplankton in a wide array of aquatic ecosystems. These organisms, in particular the genus Daphnia, have been widely used model organisms in studies ranging from biomedical sciences to ecology. Here, we present an overview of the contribution of studies with cladocerans to understanding the consequences at different levels of biological organization of stress induced by environmental factors. We discuss how some characteristics of cladocerans (e.g., small body size, short life cycles, cyclic parthenogenesis) make them convenient models for such studies, with a particular comparison with other major zooplanktonic taxa. Then we illustrate the contribution of cladocerans to stress research with examples encompassing stress responses spanning from the molecular to the populational level. Most worth of note are recent studies that presented evidence of beneficial consequences of mild stress caused by natural stressors (cross-tolerance), which may be passed along across generations, favoring individual survival and species persistence in fluctuating environments. This would be particularly relevant for environments prone to frequent natural environmental fluctuations, such as coastal lagoons and other shallow aquatic ecosystems. Based on reviewed studies, a conceptual model is presented summarizing the potential effects of a first stressor on the organism's resistance to a second one. We finish by highlighting some gaps on environmental stress research that could benefit from further studies using cladocerans as model organisms.

“…() observed Daphnia males choose deeper water strata than females and, in consequence, experience temperatures even 4°C colder than females. Similar differences lead to increased lifespan of planktonic ectotherms (e.g., rotifers: Bosque, Hernandez, Perez, Todolı, & Oltra, ; Johnston & Snell, ; copepods: Brugnano, Guglielmo, Ianora, & Zagami, ; Kiørboe, Ceballos, & Thygesen, ; cladocerans: Orcutt & Porter, ; Engert et al., ), both via physical effect of decreased metabolic rate and via changes in gene expression (Johnston & Snell, ; see also a review by Keil, Cummings, & de Magalhães, ). Indeed, Daphnia choosing deeper, and thus colder, strata have been shown to live longer (Pietrzak et al., ).…”

When males outlive females: Sex‐specific effects of temperature on lifespan in a cyclic parthenogen

Lifespans of males and females frequently differ as a consequence of different life history strategies adopted to maximize fitness. It is well visible in cyclic parthenogens, such as water fleas of the genus Daphnia, where males appear in the population usually only for periods when receptive females are available. Moreover, even within one sex, different life history strategies and mechanisms regulating lifespan may exist. Previous studies suggested that Daphnia males may regulate their lifespan by staying in colder waters than females. We hypothesize that such behavioral mechanism should be associated with stronger reaction to low temperature–that is greater lifespan extension in males than in females. In this study, we monitored survivorship of Daphnia magna females and males of three clonal lines cultured at 16 or 20°C. The results did not provide a species‐level corroboration of our hypothesis; instead, they revealed very strong intraspecific differences in the responses of male and female lifespan to temperature change. They further suggest the existence of parallel life history strategies, hypothesis whose tests would bring new insights into the ecology of males in cyclic parthenogens.
