Islands in the desert: environmental distribution modelling of endemic flora reveals the extent of Pleistocene tropical relict vegetation in southern Arabia
Background and Aims Southern Arabia is a global biodiversity hotspot with a high proportion of endemic desert-adapted plants. Here we examine evidence for a Pleistocene climate refugium in the southern Central Desert of Oman, and its role in driving biogeographical patterns of endemism. Methods Distribution data for seven narrow-range endemic... -

UAV survey at archaeological earthwork sites in the Brazilian state of Acre, southwestern Amazonia
Unmanned aerial vehicles (UAVs) are increasingly used for many scientific applications, including archaeological surveys. We test the suitability and practicability of UAV surveying in the tropical lowlands of Brazil and techniques for visualizing the resulting digital elevation models, specifically the Red Relief Image Map (RRIM). We present the results of...Saunaluoma, Sanna ; Anttiroiko, Niko ; Moat, Justin

Unearthing the “Lost” Andean Root Crop “Mauka” (Mirabilis expansa [Ruíz & Pav.] Standl.)
Although recognized as part of the vibrant array of native roots and tubers that support farmers’ livelihoods in the Andean region, the root vegetable “mauka” (Mirabilis expansa (Ruíz & Pav.) Standl.) is little known outside the scattering of communities where it is cultivated and is considered at risk of disappearance....Gendall, H. ; Seminario, J. ; Sørensen, M. ; Theilade, I.
