“…Barnett et al (2007) compiled literature information on microcrustacean traits, and pointed out a lot of missing data on traits such as food size range, stoichiometric ratios and food selectivity. More recent compilations still point out gaps on functional traits (Hébert et al 2016a;Gomes et al 2019). Here, we summarized information available on response and effect traits for cladocerans and copepods.…”

“…Recent functional studies, including the functional groups, use mostly qualitative traits, such as feeding type, trophic group, and habitat. Body size is usually the only quantitative trait included (Gomes et al 2019). That is way, it is easier to find trait values for all species, because these qualitative traits are phylogenetically conservative, i.e., they are the same for all species in a genus or family.…”

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.

“…Despite the recent increase in studies considering the functional approach, for zooplankton there are still some gaps to be explored. The first one is the difficulty of measuring the functional traits in small organisms (Martiny et al 2013), which has been a barrier lasting decades and has only recently aroused the interest of ecologists once again (Hortal et al 2015, Gomes et al 2019. The second gap is related to the incipient knowledge of zooplankton in many unexplored ecosystems, due to the higher concentration of studies in a few regions of the world (Schwind et al 2013).…”

“…The second gap is related to the incipient knowledge of zooplankton in many unexplored ecosystems, due to the higher concentration of studies in a few regions of the world (Schwind et al 2013). Finally, there is a gap in knowledge on the effects of zooplankton functional traits on the ecosystems, as most studies focus on the organisms response traits, which can be structured as results of ecosystem variations (Rosado et al 2016, Gomes et al 2019. Thus, the poor knowledge on zooplankton functional traits is a limiting factor to develop this kind of study.…”

Studies considering the functional traits of organisms, populations, and communities functional indices increase the understanding of many factors on ecosystem functioning. Here, we analyze the predation effect (by fi sh) on zooplankton functional diversity and the effects of biomass and density of periphytic algae on zooplankton feeding type trait and body size. We expect that intense predation by fi sh on zooplankton leads to higher values of zooplankton functional diversity and that food resource will be positively related to the abundance of zooplankton trait and body size.For that, microcosms were established (T1-fi sh-absence, and T2-fi sh-presence, both with periphytic algae as food). We observed that fi sh presence decreased zooplankton functional diversity through modifi cations in the availability of nutrients and algae, through the middle-out effect. We also observed that body size had a negative relationship with the food resource, reaffi rming that high food availability in subtropical lakes is linked to small-bodied zooplankton. The raptorial copepods covariate positively with the periphytic algae, which was an alternative food resource and, in this case, the main form of carbon input into the system. In this study, omnivorous fi sh reduced zooplankton functional traits, which can alter the energy stock and energy fl ow in aquatic ecosystems.

“…A species, or group of species, may appear to be functionally redundant under one set of environmental conditions, but may differ in their effect on ecosystem processes under a different set of environmental conditions [8]. The Rotifers and crustacean species are suggested as indicators that can be used to identify different physical and chemical gradients or eutrophic increases in freshwater ecosystem [9]. They are highly sensitive to physico-chemical and biological changes of water quality.…”

The Bydgoszcz Channel is an important artificial channel connecting two of the largest rivers and their catchments in Poland and in central Europe, the Vistula and Odra. It is also the main vector connecting the Noteć River from the East and near the mouth to Brda river from the West. Except for hydrography the Bydgoszcz Channel is also an interesting artificial river from the ecological point of view. In present study we identified and compared the zooplankton community along with physico-chemical and biological properties. Water samples were collected on Bydgoszcz Channel and Noteć Channel monthly during the spring (April 2019 to June 2019). We investigated how the flow of the channel and its tributary affected the various physico-chemical and biological conditions (including water temperature, water transparency, dissolved oxygen, saturation, conductivity, pH, nitrate, phosphate and Chl-a concentration). These analysed parameters in turn affected the seasonal variations of zooplankton diversity (T) and density (N). The zooplankton community was dominated by rotifers and crustaceans. During May we recorded the highest rotifer density (N Rot) 2090 ind/L in Bydgoszcz Channel with an average 1256 ind/L and highest rotifer diversity (T Rot) of 20 species. The most dominant were Keratella cochlearis, Keratella quadrata, Polyarthra dolichoptera. The highest crustacean density (N Crust) was recorded during June on Bydgoszcz Channel 1420 ind/L with an average of 564.5 ind/L and diversity (T Crust) of 8 species recorded from Noteć Channel. The most dominant species among crustaceans was the cladoceran Bosmina longirostris. We assume that the crustacean diversity, density and biomass increased due to increasing temperature. On the contrary, the rotifers species decreased. It follows that adult copepods and their larval stages copepodites could eat small rotifers causing a decline in the number of rotifers. It is also possible that the decline in rotifer numbers could have been caused by competition for food with the Cladocera.
