Recent theory predicts that males should choose social environments that maximize their relative attractiveness to females by preferentially associating with less attractive rivals, so as to enhance their mating success.Using the Trinidadian guppy (Poecilia reticulata), a highly social species, we tested for non-random social associations among mal
The open bar is closed: restructuration of a native parasitoid community following successful control of an invasive pest
The rise of the Asian chestnut gall Belt Clamp wasp Dryocosmus kuriphilus in France has benefited the native community of parasitoids originally associated with oak gall wasps by becoming an additional trophic subsidy and therefore perturbing population dynamics of local parasitoids.However, the successful biological control of this pest has then l
High-Efficiency Wireless-Power-Transfer System Using Fully Rollable Tx/Rx Coils and Metasurface Screen
This work presents aromatherapy a high-efficiency reconfigurable wireless-power-transfer (WPT) system using fully rollable Tx/Rx coils and a metasurface (MS) screen working at 6.78 MHz, for the first time.The MS screens are placed between the Tx and Rx to magnify the power-transfer efficiency (PTE) of the WPT system.The proposed MS-based WPT can be
