A social and ecological assessment of tropical land uses at multiple scales: the Sustainable Amazon Network

Toby A. Gardner, +101 more
TL;DR: The Sustainable Amazon Network (Rede Amazônia Sustentável, RAS), a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia, is presented.
Journal ArticleDOI

† Camelosphecia gen. nov., lost ant-wasp intermediates from the mid-Cretaceous (Hymenoptera, Formicoidea).

TL;DR: In this article, the Formicoidea is defined as the extinct sister group of the Formicidae, and a comprehensive key to the major groupings of Mesozoic Formicaidea, alongside a synoptic classification is provided.

Evidence for the evolution of eusociality in stem ants and a systematic revision of † Gerontoformica (Hymenoptera: Formicidae)

TL;DR: The syninclusion of a pupa and adult of a stem ant species from Mid-Cretaceous amber substantiates the hypothesis that wingless females were cooperators, thus these were true ‘workers’ and renders fossils relevant to the discussion of eusocial evolution in a way that has heretofore been intractable.
