Abstract: Notonectids are widely distributed in freshwaters and can prey on zooplankton in temperate lakes. However, its role in structuring the zooplankton community is unknown in tropical lakes. Thus, our objective was to study the notonectid Martarega uruguayensis in a Brazilian tropical shallow lake to evaluate its potential as a zooplankton predator. Its horizontal distribution was analized in the lake throughout one year in fortnightly samplings. Backswimmers were more abundant (mean density 162.9 ± 25.8 ind.m-2) … Show more

“…The abundance of A. bouvieri might be associated with the abundance of various preys. The insect feeds voraciously on fish fry, larvae, and nymphs of other aquatic insects and different types of planktonic crustaceans (Sano et al 2011;Domingos and Arcifa 2017). Many species of backswimmer have a strong preference for mosquito larvae (Weterings et al 2014).…”

“…Notonectids are able to colonize ephemeral habitat patches across landscape through aerial dispersal during their adult stage . This includes polluted aquatic habitats within urban and agro‐rural landscapes, where mosquitoes may proliferate . Given limited tolerances to pollution in wholly aquatic invertebrates (e.g.…”

“…obs.). The role of notonectids in the regulation of vector mosquito populations has been well‐documented, however studies contrasting the predatory impacts of Notonectinae and Anisopinae subfamilies within the context of habitat complexity are lacking. This is relevant given behavioral and habitat selection differences between members of these subfamilies which often co‐occur in temporary wetlands .…”

“…However, the occupation of the littoral zone of the lake can expose cladocerans to other predators that inhabit this area, including notonectids and gerrids. Notonectids occur in higher densities in the littoral zone (~ 140 ind m -2 ) than in the limnetic zone, and their juveniles preyed on Ceriodaphnia richardi and Daphnia gessneri in laboratory experiments (Domingos and Arcifa, 2017a). Gerrids are also more abundant in the littoral zone, although at lower densities (~ 7 ind m -2 ) than notonectids (Domingos and Arcifa, 2017b).…”
