      Identification of ungulates used in a traditional Chinese medicine with DNA barcoding technology

      Jing Chen, Zhigang Jiang, Chunlin Li, Xiaoge Ping, Shaopeng Cui, Songhua Tang, Hongjun Chu and Binwan Liu

      Article first published online: 8 APR 2015 | DOI: 10.1002/ece3.1457

      “Lingyangjiao”, a traditional Chinese medicine (TCM), was specified to be horns of Saiga antelope, but recently horns of the other seven species were sold as substitutes in TCM markets. Difficulty of diagnosis of these similar horns impeded not only management of trade of Saiga horns but also conservation strategies for these endangered species. We extracted genomic DNA from horns samples and implemented DNA barcoding technology to diagnose species whose horns were sold as “Lingyangjiao” in TCM markets.

      Condition, not eyespan, predicts contest outcome in female stalk-eyed flies, Teleopsis dalmanni

      Eleanor Bath, Stuart Wigby, Claire Vincent, Joseph A. Tobias and Nathalie Seddon

      Article first published online: 8 APR 2015 | DOI: 10.1002/ece3.1467

      Condition determines the outcome of intrasexual competition in female stalk-eyed flies (Teleopsis dalmanni). In addition, we find that an exaggerated condition-dependent trait (eyespan), which has previously been thought to be a better predictor of contest outcome in male stalk-eyed flies, does not provide any additional benefit to either sex in intrasexual competition.

      Intervarietal and intravarietal genetic structure in Douglas-fir: nuclear SSRs bring novel insights into past population demographic processes, phylogeography, and intervarietal hybridization

      Marcela van Loo, Wolfgang Hintsteiner, Elisabeth Pötzelsberger, Silvio Schüler and Hubert Hasenauer

      Article first published online: 3 APR 2015 | DOI: 10.1002/ece3.1435

      This study examined the genetic structure of the North American conifer Douglas-fir (Pseudotsuga menziesii) and its two hybridising varieties, coastal and Rocky Mountain, at intervarietal and intravarietal level using 13 nuclear SSRs. The genetic structure was subsequently associated with the Pleistocene refugial history, postglacial migration and inter-varietal hybridisation/introgression.

      Predicting dispersal of auto-gyrating fruit in tropical trees: a case study from the Dipterocarpaceae

      James R. Smith, Robert Bagchi, Judith Ellens, Chris J. Kettle, David F. R. P. Burslem, Colin R. Maycock, Eyen Khoo and Jaboury Ghazoul

      Article first published online: 2 APR 2015 | DOI: 10.1002/ece3.1469

      This article experimentally investigates seed dispersal potential in the Dipterocarpaceae, a family of trees with winged, wind dispersed fruit which dominates the tropical forests of Southeast Asia. Seed dispersal of all species was predominantly local, with 90% of seed dispersing <10 m. We present a generic seed dispersal model for dipterocarps based on attributes of seed morphology, and provide modelled seed dispersal kernels for all dipterocarp species with inverse wing loadings (area of fruit wings/mass of fruit) of 1–50, representing 75% of species in Borneo.

      Seaweed fails to prevent ocean acidification impact on foraminifera along a shallow-water CO2 gradient

      Laura R. Pettit, Christopher W. Smart, Malcolm B. Hart, Marco Milazzo and Jason M. Hall-Spencer

      Article first published online: 31 MAR 2015 | DOI: 10.1002/ece3.1475

      There is a suggestion that photosynthetic organisms could mitigate ocean acidification on a local scale. Here, we used a natural gradient in calcium carbonate saturation to assess whether seaweed that is resistant to acidification (Padina pavonica) could prevent adverse effects of acidification on epiphytic foraminifera. We found that the assemblage shifted from one dominated by calcareous species at reference sites (pH ~8.19) to one dominated by agglutinated foraminifera at elevated levels of CO2 (pH ~7.71).

      Explaining forest productivity using tree functional traits and phylogenetic information: two sides of the same coin over evolutionary scale?

      Alain Paquette, Simon Joly and Christian Messier

      Article first published online: 27 MAR 2015 | DOI: 10.1002/ece3.1456

      Thumbnail image of graphical abstract

      The importance of biodiversity for ecosystem functioning and for the provisioning of services to humanity is well established. Yet we still are looking for methods to quantify this biodiversity that are both relevant and efficient. Here we show that phylogenetic information can help, especially when key functional traits are unavailable, and how it relates to functional traits of species.
