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... -

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.

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... -

Reconciling Darwin’s naturalization and pre‐adaptation hypotheses: An inference from phylogenetic fields of exotic plants in Japan
Aim Understanding the causes and consequences of biological invasions remains a challenge for several disciplines, including biogeography. One major issue in overcoming this challenge is disentangling the confounding mechanisms of species invasiveness and community invasibility. Here, we tackle this issue by applying a novel approach based on the phylogenetic affinities...Kusumoto, Buntarou ; Villalobos, Fabricio ; Shiono, Takayuki ; Kubota, Yasuhiro

Hyb-Seq for Flowering Plant Systematics
High-throughput DNA sequencing (HTS) presents great opportunities for plant systematics, yet genomic complexity needs to be reduced for HTS to be effectively applied. We highlight Hyb-Seq as a promising approach, especially in light of the recent development of probes enriching 353 low-copy nuclear genes from any flowering plant taxon. -

Shift in flowering time allows diploid and autotetraploid Anacamptis pyramidalis (Orchidaceae) to coexist by reducing competition for pollinators
How autopolyploids establish when competing with diploid progenitors is still poorly understood. Here, we investigate the effects of morphological and phenological divergence on the reproductive success of co-occurring diploid and autotetraploid individuals of Anacamptis pyramidalis to disentangle the mechanisms allowing their c-oexistence. We estimated reproductive success in terms of absolute... -

Enhancing identification accuracy for powdery mildews using previously underexploited DNA loci
The internal transcribed spacer (ITS) DNA marker is routinely used for fungal identification but gives a clear result for only three out of four powdery mildew samples. A search for new markers indicates that some genes offer enhanced identification in comparison with ITS. Others fail due to amplification and sequencing...Ellingham, Oliver ; David, John ; Culham, Alastair

Ex situ conservation storage potential of Saxifraga cernua (Saxifragaceae) bulbils from alpine species
In high latitude and alpine environments many plants show an increase in viviparous reproduction in response to harsh environmental conditions. Low or no seed set means that ex situ conservation in the form of seed banking is not a conservation option for such species. We investigated the potential for bulbils...Breman, Elinor ; Détraz-Méroz, Jacqueline ; Terry, Janet ; Lambelet, Catherine
