Heavy sea louse infection is associated with decreased stomach fullness in wild juvenile sockeye salmon

open access: yesCanadian Journal of Fisheries and Aquatic Sciences, 2018
Foraging success can be mediated by parasites, but this is poorly understood for marine fish whose aggregations and patchy prey fields create conditions for intense intraspecific competition.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, EarlyView.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

THE DESTRUCTIVE GREEN–PEA LOUSE [PDF]

open access: yesThe Canadian Entomologist, 1900
Perhaps never in the history of economic entomology has an undescribed species of insect appeared so suddenly and over such a wide area, and in such destructive numbers, as the “destructive green-pea louse,” the popular name I have given the insect herein described.
