Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean
Isotopic niches trophic levels myctophid fishes their predators in the Southern Ocean
2014/4/16
We report the trophic structure of a myctophid assemblage by measuring theisotopic niches of 14 species living in Kerguelen waters, southern Indian Ocean. Most of the species show distinct isotopic ni...
No empirical evidence for community-wide top-down control of prey fish density and size by fish predators in lakes
No empirical evidence community-wide top-down control prey fish density size by fish predators in lakes
2014/4/16
I tested relationships between fish predator and prey densities or size across 66 lakes of the European temperate zone, covering mean depths between 1 and 22 m and a phytoplankton biomass range betwee...
Two-step dialogue between the cladoceranBosminaand invertebrate predators: Induction and natural selection
Two-step dialogue cladocera Bosmina invertebrate predators: Induction natural selection
2014/4/16
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...
Voracity of Three Predators on Two-Spotted Spider Mite, Tetranychus Urticae Koch (Acari: Tetranychidae) and Their Developmental Stages
Voracity Tetranychus urticae Scolothrips sexmaculatus Phytoseiulus persimilis and Stethorus punctillum
2010/11/15
Three predators Phytoseiulus persimilis Athias-Henriot, Stethorus punctillum Weise and
Scolothrips sexmaculatus Pergande, were used to test their voracity on two-spotted spider mite, Tetranychus urti...

Effects of Neem and Diatomaceous Earth Against Myzus Persicae and Associated Predators in Addition to Indirect Effects on Artichoke Growth and Yield Parameters
Aphids artichoke diatomaceous earth neem predators vegetative growth yield parameters
2010/11/10
An important pest on artichoke is green peach aphid, Myzus persicae (Sulzer). The associated
predators of M. persicae, such as the coccinelids, Chrysopid and Anthocorids were recorded. In the present...
