Optimized early detection of aquatic invasive species using a community rarity index
Ecological Solutions and EvidenceFollowing their introduction, invasive species management is most successful and cost‐effective when new invaders are detected while still rare. Given the low capture probability for extremely rare species, early detection programmes for aquatic invasive

High Voltage, EarlyView.ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.
