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

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

Native Useful Plants of Chile: A Review and Use Patterns
We compiled an inventory of the uses of the native flora of Chile by extracting uses cited in the literature until 2015. The inventory reported use citations for a total of 995 species of useful vascular plants (23% of Chile’s flora). These data were used to test the hypothesis that...Díaz-Forestier, Javiera ; León-Lobos, Pedro ; Marticorena, Alicia ; Celis-Diez, Juan ; Giovannini, Peter

Current and future potential distributions of three Dracaena Vand. ex L. species under two contrasting climate change scenarios in Africa
Forest undergrowth plants are tightly connected with the shady and humid conditions that occur under the canopy of tropical forests. However, projected climatic changes, such as decreasing precipitation and increasing temperature, negatively affect understory environments by promoting light‐demanding and drought‐tolerant species. Therefore, we aimed to quantify the influence of climate...Bogawski, Paweł ; Damen, Theo ; Nowak, Maciej ; Pędziwiatr, Katarzyna ; Wilkin, Paul …

Population structure of Betula albosinensis and Betula platyphylla: evidence for hybridization and a cryptic lineage
Background and Aims Differences in local abundance and ploidy level are predicted to impact the direction of introgression between species. Here, we tested these hypotheses on populations of Betula albosinensis (red birch) and Betula platyphylla (white birch) which were thought to differ in ploidy level, the former being tetraploid and...Hu, Ya-Nan ; Zhao, Lei ; Buggs, Richard ; Zhang, Xue-Min ; Li, Jun …

Ecological speciation in sympatric palms: 3. Genetic map reveals genomic islands underlying species divergence in Howea
Although it is now widely accepted that speciation can occur in the face of continuous gene flow, with little or no spatial separation, the mechanisms and genomic architectures that permit such divergence are still debated. Here, we examined speciation in the face of gene flow in the Howea palms of...Papadopulos, Alexander ; Igea, Javier ; Dunning, Luke ; Osborne, Owen ; Quan, Xueping …
