Acantholeberis smirnovi Paggi & Herrera-Martinez, 2020 (Cladocera: Acantholeberidae) was recently described from Andean habitats in South America. The presence of a population on the eastern coast of the continent brought the hypothesis of a new Neotropical species different from A. smirnovi. This hypothesis was confirmed from morphological, ecological and biogeographic evidence. Acantholeberis accolismaris Sousa, Elmoor-Loureiro & Álvarez-Silva sp. nov. differs from A. smirnovi in the morphology of the head, the valves and the limbs (especially the second and third limbs). Species of Acantholeberis are adapted to live in acid water bodies, with A. accolismaris sp. nov. presenting the same ecological requirements. However, the new species is adapted to live in temporary ponds near the Atlantic Ocean in Brazil in altitudes ranging between 4 and 15 meters above sea level. Considering that Acantholeberidae is an ancient taxon with a pre-Mesozoic origin, geological and environmental changes may have been relevant to speciation and to the observed biogeographic pattern of species of Acantholeberis in Neotropics.

“…The experiment had a duration of 45 days (August–September 2017). The hatchlings were collected three times a week over this period to prevent reproduction (Freiry et al, 2020; Freiry, Weber, et al, 2020). Hatchling collection was performed with three consecutive sweeps on the surface water after kicking the sediment with a hand‐net of the same dimensions of the tray and 50‐μm mesh size.…”

“…Several studies conducted with the active community showed that the richness and the composition of zooplankton species pools differ among climatic regions and respond to a wide range of local (site‐level) environmental variables (water chemistry, habitat structure and so on) (De Bie et al, 2012; Eitam, Blaustein, Van Damme, Dumont, & Martens, 2004; Kruk et al, 2009; Perbiche‐Neves et al, 2019; Santangelo et al, 2015; Viana et al, 2016; Waterkeyn, Vanschoenwinkel, Vercampt, Grillas, & Brendonck, 2011). The spatial configuration of a study region can also be associated with zooplankton community structure, geographically closer sites can show more similar composition (Freiry et al, 2020; Santangelo et al, 2015). Also, dispersal by wind may directly shape the zooplankton communities by the introduction of immigrants and indicating that spatial predictors should also be taken into account in the assessment of zooplankton community structure (Horváth, Vad, & Ptacnik, 2016; Vanschoenwinkel, Gielen, Seaman, & Brendonck, 2009).…”

Most zooplankton species inhabiting seasonal ponds produce dormant stages to overcome the dry seasons. Zooplankton specimens emerging from the sediment contribute to the ecological dynamics of these ecosystems, because they constitute important energy sources for higher trophic levels in aquatic food webs. In contrast to snapshot studies of the active communities, studying the ecological correlates of the distribution of the egg bank can help identify the potential drivers of zooplankton composition. We tested the association of local (habitat structure and water chemistry), climatic and spatial predictors with the alpha and beta diversity of zooplankton hatchling communities in subtropical seasonal ponds. Incubation experiments were conducted with sediment samples from 11 ponds distributed along an approximately 500‐km latitudinal gradient in southern Brazil. We assessed the patterns for the total community, Cladocera only and Rotifera only. The alpha diversity of the total community and Cladocera were primarily related to substrate heterogeneity. Annual rainfall and substrate heterogeneity jointly influenced the beta diversity of the total community. Annual rainfall solely influenced the beta diversity of Cladocera, while substrate heterogeneity influenced the overall beta diversity of Rotifera. Overall, the distinct relationships of the total hatchling community and Cladocera and Rotifera with the explanatory datasets suggest differing sensitivities of the zooplankton groups to impacts in habitat structure and climatic conditions in subtropical seasonal ponds.

“…To our knowledge, this is the first documentation of such patterns for macroinvertebrates in wetlands, particularly in spring helocrenes, at the within-site spatial scale. Similar studies on freshwater invertebrates have only been conducted for stream macroinvertebrates (Costa & Melo, 2008), zooplankton communities or their resting stages (Chaparro et al, 2018;Freiry et al, 2020). They decomposed beta diversity across multiple spatial scales, detecting high (Chaparro et al, 2018;Costa & Melo, 2008) or low (Chaparro et al, 2018;Freiry et al, 2020) contribution of EH at the within-site scales.…”

Spring helocrenes are a unique aquatic environment with high biotic diversity. Although environmental heterogeneity has traditionally been assumed to explain the high species richness of spring habitats, this assumption has never been properly tested. Here, we sampled macroinvertebrates from two calcareous helocrenes in Slovakia with visually distinguishable mesohabitat heterogeneity. We hypothesise that macroinvertebrate beta diversity significantly increases with environmental heterogeneity even at a small within‐site spatial scale. We also examined four species‐trait categories, that is, active or passive dispersers and habitat specialists or generalists. Significant spatial structuring of environmental heterogeneity was found at one site, whereas the other site did not show a clear spatial pattern. Strong associations were found between beta diversity of all species trait categories and environmental heterogeneity at the first site, while there were virtually no associations at the second site. Specialists were not spatially structured at any of the sites examined. Our results suggest that invertebrate beta diversity responds positively to environmental heterogeneity at a site by also tracking spatial structuring of abiotic conditions. However, the response may vary depending on the dispersal mode and habitat specialisation of the invertebrates.
