Última Hide and seek in the Bay of Biscaya functional investigation of marine megafauna and small pelagic fish interactions ArchiMer Lambert, Charlotte; Authier, Matthieu; Doray, Mathieu; Doremus, Ghislain; Spitz, Jerome; Ridoux, Vincent. Prey and predator distributions influence one another. Understanding the scale and the orientation of predator-prey spatial correlations is crucial in foraging ecology. Growing evidence suggests that predator-prey interactions are more constrained by functional characteristics of both the predator and the prey. Unfortunately, in marine pelagic systems, the scale and orientation of spatial correlations between predators and prey have been only little explored from a functional point of view. We tested the existence of fine-scale association between predators and fish functional groups. Visual predator sightings and acoustic fish records were collected synchronously during oceanographic surveys from 2004 to 2014. Prey biomass was integrated by nautical miles...

Ano: 2019 URL: https://archimer.ifremer.fr/doc/00488/59998/63448.pdf Chemically mediated intraguild predator avoidance by aphid parasitoids: Interspecific variability in sensitivity to semiochemical trails of ladybird predators OAK Nakashima, Yoshitaka; Birkett, Michael A.; Pye, Barry J.; Powell, Wilf; 仲島, 義貴. The avoidance responses of aphid parasitoids with varying host ranges (Aphidius eadyi, Aphidius ervi, and Praon volucre) to chemical trails deposited by intraguild predatory ladybirds, Coccinella septempunctata and Adalia bipunctata, were investigated. Females of all three parasitoid species avoided leaves previously visited by C. septempunctata or A. bipunctata adults. The avoidance responses shown by the two Aphidius species were stronger to trails of C. septempunctata than to those of A. bipunctata. However, P. volucre avoided trails of both ladybird species to a similar degree. Dose responses of these three parasitoid species to the hydrocarbons n-tricosane (C23H48), n-pentacosane (C25H52), and n-heptacosane (C27H56), which are components of the trails...

Ano: 2003 URL: http://ir.obihiro.ac.jp/dspace/handle/10322/807 The role of semiochemicals in the avoidance of the seven-spot ladybird, Coccinella septempunctata, by the aphid parasitoid, Aphidius ervi OAK Nakashima, Yoshitaka; Birkett, Michael A.; Pye, Barry J.; Pickett, John A.; Powell, Wilf; 仲島, 義貴. The role of semiochemicals in mediating intraguild interactions between the seven-spot ladybird, Coccinella septempunctata, and the aphid parasitoid, Aphidius ervi, was investigated. Female parasitoids avoided leaves visited by C. septempunctata adults and larvae during the previous 24 hr. Ethanol extracts of C. septempunctata adults and larvae also induced avoidance responses by A. ervi. Two of the hydrocarbons identified by gas chromatography ( GC) and coupled GC-mass spectrometry (GC-MS), n-tricosane (C23H48), and n-pentacosane (C25H52), when tested individually at levels found in the adult extract, induced avoidance by A. ervi. Further investigation of the larvae extract, and footprint chemicals deposited by adults in glass Petri dishes, confirmed the...
