Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
Caudal fin-nipping by Serrasalmus maculatus (Characiformes: Serrasalmidae) in a small water reservoir: seasonal variation and prey selection
(Soc Brasileira Zoologia, Univ Federal Parana, 2015-12-01)
We evaluated how seasonality affects the frequency and intensity of fin-nipping, as well as the fish prey preferences of Serrasalmus maculatus Kner, 1858. The study took place in a small reservoir of the Ribeirao Claro ...
The effects of plant structure on the spatial and microspatial distribution of a bromeliad-living jumping spider (Salticidae)
(Blackwell Publishing LtdOxfordInglaterra, 2005)
Subsidies to predators, apparent competition and the phylogenetic structure of prey communities
(2013)
Ecosystems are fragmented by natural and anthropogenic processes that affect organism movement and ecosystem dynamics. When a fragmentation restricts predator but not prey movement, then the prey produced on one side of ...
Medium-sized exotic prey create novel food webs: The case of predators and scavengers consuming lagomorphs
(PeerJ Inc., 2016-07)
Food web interactions are key to community structure. The introduction of species can be seen as an uncontrolled experiment of the addition of species. Introduced species lead to multiple changes, frequently threatening ...
Zooplankton capturing by Nile Tilapia, Oreochromis niloticus (Teleostei: Cichlidae) throughout post-larval development
(Soc Brasileira Zoologia, Univ Federal Parana, 2015-12-01)
The Nile tilapia, Oreochromis niloticus (Linnaeus, 1758), uses filter feeding and visual predation to catch prey. In filter feeding, the mucus secreted in their gill rakers traps planktonic organisms. In visual predation, ...
Effect of habitat complexity on the predation of Buenoa fuscipennis (Heteroptera: Notonectidae) on mosquito immature stages and alternative prey
(Wiley, 2013-11)
Notonectids are well-known predators in aquatic habitats, where mosquito larvae, chironomids and cladocerans constitute their main diet. Here we aimed to assess the effect of structural complexity on the predatory ability ...
