This paper presents the implementation and design of a wireless sensor network developed to facilitate indoor mobile robot localization. The sensor network consists of homogeneous nodes, termed the Parrot, that can measure range to other nodes within the network using ultrasonic signals. This information provides algorithms running on mobile and static nodes to analyze and learn their physical ...

Abstract The decision to intervene in endangered species management is often complicated. Migratory exemplify this difficulty because they experience diverse threats at different times and places that can act cumulatively synergistically on their populations. We use population viability analysis (PVA) compare potential conservation interventions the critically endangered, migratory Orange-belli...

In 12 keeping communities, we carried out in-depth interviews 106 people, quantify ownership, trapping, interviewees’ attitudes towards behaviours. combined data calcul...
