Interaction of functional and environmental traits on seed germination of the multipurpose tree Flacourtia indica
Flacourtia indica (Salicaceae) is a multipurpose tree native to tropical regions of Africa and India, where it is mainly used for food and medicines. Its use in reforestation is limited by poor knowledge of its seed biology and germination ecology. The aim of this study was to determine how its... -

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.

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

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... -

General sampling guide for timber tracking: how to collect reference samples for timber identification
This is a guide for the collection of reference samples of trees to enable the identification of species and/or geographical origin of woody material. It is an update of the sampling section of the GTTN standards and guidelines (Ekué 2014) and builds further on a discussion initiated during a workshop... -

Phylogenomic Relationships of Diploids and the Origins of Allotetraploids in Dactylorhiza (Orchidaceae)
Disentangling phylogenetic relationships proves challenging for groups that have evolved recently, especially if there is ongoing reticulation. Although they are in most cases immediately isolated from diploid relatives, sets of sibling allopolyploids often hybridize with each other, thereby increasing the complexity of an already challenging situation. Dactylorhiza (Orchidaceae: Orchidinae) is...Brandrud, Marie K ; Baar, Juliane ; Lorenzo, Maria T ; Athanasiadis, Alexander ; Bateman, Richard M …

Dichotomous keys to the species of Solanum L. (Solanaceae) in continental Africa, Madagascar (incl. the Indian Ocean islands), Macaronesia and the Cape Verde Islands
Solanum L. (Solanaceae) is one of the largest genera of angiosperms and presents difficulties in identification due to lack of regional keys to all groups. Here we provide keys to all 135 species of Solanum native and naturalised in Africa (as defined by World Geographical Scheme for Recording Plant Distributions):...Knapp, Sandra ; Vorontsova, Maria S. ; Särkinen, Tiina

Coping with ill-health: health care facility, chemist or medicinal plants? Health-seeking behaviour in a Kenyan wetland
Background Sub-Saharan African wetlands, settlement areas to growing populations, expose their users to diseases as necessary health infrastructure remains underdeveloped. Methods Mixed methods were adopted to assess the health-seeking behaviour of different exposure groups (farmers, pastoralists, service sector workers) in a Kenyan wetland community. Based on a cross-sectional survey (n = 400),...Anthonj, Carmen ; Giovannini, Peter ; Kistemann, Thomas
