Journal ArticleDOI
Trophic cascades : the primacy of trait-mediated indirect interactions
TL;DR: It is shown that simple trade-off behaviour can lead to both positive and negative indirect effects of predators on plant resources and hence can explain considerable contingency on the nature and strength of cascading effects among systems.
Journal ArticleDOI
Factors Influencing Site Abandonment and Site Selection in a Sit-and-Wait Predator: A Review of Pit-Building Antlion Larvae
Inon Scharf,Ofer Ovadia +1 more
TL;DR: This synthesis shows that prey abundance may have relatively little effect on pit relocation and that physical properties of the habitat or competition often override its effect, and proposes new research directions, such as studying whether pit relocation is an adaptive response, when controlling for possible phylogenetic effects.
Journal ArticleDOI
Foraging decisions and behavioural flexibility in trap-building predators: a review.
TL;DR: Evidence is provided that the behaviour of trap‐building predators is not stereotypic or fixed as was once commonly accepted, rather it can vary greatly, depending on the individual's internal state and its interactions with external environmental factors.
Journal ArticleDOI
Efficiency Evaluation of Two Competing Foraging Modes under Different Conditions
TL;DR: It is suggested that the simulation model used to test the relative success of an ambush and an active predator changes as a function of the relative velocity and movement directionality of prey and active predator is a better predictor of encounter rates than previous studies.
Journal ArticleDOI
Core gut microbial communities are maintained by beneficial interactions and strain variability in fish.
Fotini Kokou,Fotini Kokou,Goor Sasson,Jonathan Friedman,Stav Eyal,Ofer Ovadia,Sheenan Harpaz,Avner Cnaani,Itzhak Mizrahi +8 more
TL;DR: The authors investigated microbial communities at three sites in the guts of European seabass under four dietary conditions and identified generalist core microbial populations in each gut site that are shared across fish, present under multiple diets and persistent over time.
