Studies considering the functional traits of organisms, populations, and communities indices increase understanding many factors on ecosystem functioning. Here, we analyze predation effect (by fish) zooplankton diversity effects biomass density periphytic algae feeding type trait body size. We expect that intense by fish leads to higher values food resource will be positively related abundance For that, microcosms were established (T1- fish-absence, T2- fish-presence, both with as food). observed presence decreased through modifications in availability nutrients algae, middle-out effect. also size had a negative relationship resource, reaffirming high subtropical lakes is linked small-bodied zooplankton.

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

Despite the key role of zooplankton communities in regulating water quality lentic ecosystems, they are absent from list biological elements Water Framework Directive (WFD) for assessment ecological status. Based on this, present work was a case study that aimed to understand relevance as bioindicator classifying reservoirs. For one year and each season, Torrão reservoir assessed using mandatory proposed by WFD sampling (second cycle) legislation currently applicable (third cycle). Additionally, samples were collected characterize community dynamic. The does not reach good potential. Furthermore, with updating criteria, classification tends get worse. Concerning zooplankton, occurrence Cyclopoida Bosmina associated lower quality, well collapse or low abundance Daphnia population, same periods. Low abundances better Shannon-Wiener diversity values decrease increase trophic state. High-efficiency feed filters macrofiltrator organisms dominate all seasons, which is quality. Calanoida/Cyclopoida ratio shows strong negative association species, diversity, functional groups (high efficiency macrofiltrators), different ratios (large Cladocera/total Cladocera Calanoida/Cyclopoida) promising valuable tools determine status, should be considered within metrics. Notwithstanding further research including reservoirs geographical areas various status pressures must analyzed.

In recent years, lakes’ water quality and quantity have been affected damaged by agricultural activities. The sensitivity of phytoplankton to the hydrological environment can effectively indicate health aquatic ecosystem change in quality. Understanding changes communities lakes contaminated agriculture may contribute determining directions protection these bodies provide reference cases for wider research. It is found that there are 146 species, 63 genera, 8 phyla phytoplankton, including 57 species Bacillariophyta, 46 Chlorophyta, 17 Cyanobacteria Euglenophyta. total abundance was changed successively with Bacillariophyta (75% June), (50% July–August), Chlorophyta September–October). biomass decreased continuously over time. highest October (67.4%), diatoms most other months (76.5%).

Abstract Compiling trait information promotes discovery and innovation in using trait‐based approaches ecology. Various zooplankton datasets are stored unlinked data repositories, diverse structures, have varying levels of complexity.

Zooplankton as an essential component in the pelagic food web are directly linked to ecosystem functioning. Therefore, comprehension of zooplankton functional diversity (FD) and its responses environmental changes is crucial for ecosystem-based view. To identify FD drivers, we analysed 25 years summer data on brackish mesozooplankton community (including rotifers, cladocerans, copepods, meroplankton) from eutrophied, shallow Gulf Riga (Baltic Sea). We established that within Riga, open waters notably different coastal regions based dynamics hydrological conditions (temperature, salinity), cyanobacterial dominance, abundance groups, indices. Competition over resources combination with hydrodynamic features predation by adult herring were seemingly central structuring mechanism behind metrics (richness, evenness, divergence, dispersion) communities. Whereas young was important driver only communities waters. Cyanobacterial used a proxy quality availability, had no effect metrics.
