“…S3). Previous study on crustacean zooplankton in the SYS also revealed the dominance of free spawners, the dynamics of which were driven by hydrological seasonality (Li et al 2022). It has been reported that free spawners dominate in coastal regions, for example, the coastal region of the Southwestern Atlantic (Da Conceição et al 2021) exhibit high fecundity and egg-laying in environments with high Chl a (Bunker and Hirst 2004).…”

Functional traits determine the fitness of organisms and mirror their ecological functions. Although trait-based approaches provide ecological insights, it is underexploited for marine zooplankton, particularly with respect to seasonal variation. Here, based on four major functional traits, including body length, feeding type, trophic group, and reproduction mode, we quantified the seasonal variations of mesozooplankton functional groups in the South Yellow Sea (SYS) in the spring, summer, and autumn of 2018. Strong seasonal dynamics were identified for all traits but patterns varied among traits. Small zooplankton (47.7–88.6%), omnivores–herbivores (81.3–97.6%), and free spawners (54.8–92.5%) dominated in three seasons, while ambush feeders and current feeders dominated in spring (45.7%), and autumn (73.4%), respectively. Cluster analysis of the functional traits showed that the mesozooplankton in the SYS can be classified into eight functional groups. The biogeographic and seasonal variations of functional groups can be partially explained by environmental drivers. Group 1, represented by omnivores–herbivores, was the most dominant functional group, the abundance of which peaked in spring and was positively correlated with chlorophyll a concentration, indicating its close association with phytoplankton dynamics. The contribution of giant, active ambush carnivores, passive ambush carnivore jellyfish, current omnivores–detritivores, and parthenogenetic cladocerans increased with sea surface temperature. The proportion of giant, active ambush carnivores and active ambush omnivore–carnivore copepods decreased with salinity in autumn. This study presents a new perspective for understanding the dynamics of zooplankton and paves the way for further research on the functional diversity of zooplankton in the SYS.

“…Thus, current feeding herbivores may be more advantageous, as observed in these two stations. In terms of reproduction mode, high turbidity facilitates egg-brooders to avoid visual predators (Holliday & Lawrence, 2001) but reduces the survival rate of free-spawners egg (Li et al, 2022), which may explain that egg-brooder dominated in the two stations in summer and station 2-1 in winter-spring when turbidity is high, while broadcast spawners dominated in the two stations in autumn and station 2-2 in winter-spring when the salinity wedge was far away. We further clustered taxon into functional groups and analysed the seasonality of functional structure of zooplankton.…”

“…Zooplankton community had been well studied by taxonomic‐based approaches in CRE, for example the seasonal changes (Shao et al, 2017), the responses to CDW and TWC (Chen et al, 2011; Gao et al, 2011) and the dynamics under eutrophication and hypoxia (Feng & Liu, 2019; Li et al, 2010). Despite increasing studies have revealed the zooplankton dynamics in China's marginal seas, to our best knowledge, trait‐based approach has rarely been used (Li et al, 2022; Zhang et al, 2021), particularly in China's estuaries. The seasonal variations of zooplankton functional trait, group and diversity in CRE remain unclear, which impede our further understanding on biodiversity and ecology health in estuary ecosystems.…”

“…Studies regarding zooplankton functional traits mainly focus on freshwater habitats and crustaceans, probably due to the high abundance and wide geographical distribution of these animals (Barnett et al, 2007;Vogt et al, 2013;Hebert and Beisner, 2021). Recently, studies in marine waters have offered an integrative approach to the function of zooplankton communities (Pomerleau et al, 2015;Li et al, 2022). In estuaries, field observations indicated that major changes in composition and diversity of zooplankters occur at 25 psu salinity level (Li et al, 2006).…”

Zooplankton functional traits in a tropical estuarine system: Are lower and upper estuaries functionally different?

Functional diversity measures help to understand the underlying mechanisms explaining the relationship between organisms and environment. This work examined the mesozooplankton community of an estuary under the hypothesis that the upper (< 25 psu) and lower (> 25 psu) zones are functionally different in terms of feeding strategies, trophic groups, camouflage, buoyancy, and defense against predators, due to the salinity gradient. We used the ‘community-weighted mean trait values’ (CWM) and a fuzzy correspondence analysis (FCA) in combination with three functional indices (FRic: functional richness, FEve: functional evenness, FDiv: functional divergence) to test our hypothesis. Zooplankton samples were taken in the tropical Sontecomapan estuary, southern Gulf of Mexico, in June 2018 and October 2019. A total of 21 zooplankton groups were recognized, all of them present in the lower estuary. Results showed significant differences (p< 0.05) in the FRic and FDiv values between the two zones, as well in the CWM metric. Results of the FCA showed that the lower estuary was characterized by herbivorous filter feeders that use watery bodies, flattened body forms, mucus houses, or ‘wings’ for buoyancy; highly transparent bodies (associated with gelatinous body structure) for camouflage and predators’ avoidance and, shells or carapaces as antipredator tactics. The upper estuary was characterized by omnivorous cruising predators that use their appendages or swim bladders for buoyancy, with ‘medium’ and ‘low’ levels of transparency, associated with chitinous and skin-protected body structures, which provide alternative ways for camouflage and spines or fast swimming behavior to protect from predators. These findings evidenced that the upper and lower zones of an estuary exhibit differences in the function of the zooplankton community and shed new light on the comprehension of estuaries’ ecological function.
