Prey conspicuousness can explain apparent prey selectivity
daughters. However, our finding that α α-males sired their daughters' offspring less frequently than non-daughters' offspring remains highly significant when the analysis is restricted to the 34 offspring known to have been born to non first time mothers (Fisher's exact p = 0.0003). A third alternative explanation for our findings is that father–daughter matings are not avoided, but when they ...
متن کاملSupplemental Data: Prey Conspicuousness Can Explain Apparent Prey Selectivity
Supplemental Experimental Procedures Determination of prey abundance The field study was conducted using a colony of 300 M. myotis roosting in a church at Flawil, eastern Switzerland. The abundance of epigaeic arthropods was measured using pitfall traps (16 cm diameter, 4% formaldehyde, 10 m spacing between the 3 to 5 traps) in four forest and four grassland sites which had been identified as m...
متن کاملUnidirectional prey–predator facilitation: apparent prey enhance predators' foraging success on cryptic prey
Food availability can strongly affect predator-prey dynamics. When change in habitat condition reduces the availability of one prey type, predators often search for other prey, perhaps in a different habitat. Interactions between behavioural and morphological traits of different prey may influence foraging success of visual predators through trait-mediated indirect interactions (TMIIs), such as...
متن کاملConcealed by conspicuousness: distractive prey markings and backgrounds.
High-contrast markings, called distractive or dazzle markings, have been suggested to draw and hold the attention of a viewer, thus hindering detection or recognition of revealing prey characteristics, such as the body outline. We tested this hypothesis in a predation experiment with blue tits (Cyanistes caeruleus) and artificial prey. We also tested whether this idea can be extrapolated to the...
متن کاملPiscivore-Prey Fish Interactions: Mechanisms behind Diurnal Patterns in Prey Selectivity in Brown and Clear Water
Environmental change may affect predator-prey interactions in lakes through deterioration of visual conditions affecting foraging success of visually oriented predators. Environmental change in lakes includes an increase in humic matter causing browner water and reduced visibility, affecting the behavioural performance of both piscivores and prey. We studied diurnal patterns of prey selection i...
