Savanna research on the impact of these drivers has widely applied the so-called plant functional type (PFT) approach, grouping the vegetation into two or three broad types (here called meta-PFTs): woody plants and grasses, which are sometimes divided into perennial and annual grasses. However, little is known about the response of functional traits within these coarse types towards water availability or livestock grazing. In this study, we extended an existing eco-hydrological savanna vegetation model to capture trait diversity within the three broad meta-PFTs to assess the effects of both grazing and mean annual precipitation (MAP) on trait composition along a gradient of both drivers. Our results show a complex pattern of trait responses to grazing and aridity. The response differs for the three meta-PFTs. From our findings, we derive that trait responses to grazing and aridity for perennial grasses are similar, as suggested by the convergence model for grazing and aridity. However, we also see that this only holds for simulations below a MAP of 500 mm. This combined with the finding that trait response differs between the three meta-PFTs leads to the conclusion that there is no single, universal trait or set of traits determining the response to grazing and aridity. We finally discuss how simulation models including trait variability within meta-PFTs are necessary to understand ecosystem responses to environmental drivers, both locally and globally and how this perspective will help to extend conceptual frameworks of other ecosystems to savanna research.}, language = {en} } @article{KetenogluSpiekermannHarderetal.2018, author = {Ketenoglu, Didem and Spiekermann, Georg and Harder, Manuel and Oz, Erdinc and Koz, Cevriye and Yagci, Mehmet C. and Yilmaz, Eda and Yin, Zhong and Sahle, Christoph J. and Detlefs, Blanka and Yavas, Hasan}, title = {X-ray Raman spectroscopy of lithium-ion battery electrolyte solutions in a flow cell}, series = {Journal of synchrotron radiation}, volume = {25}, journal = {Journal of synchrotron radiation}, publisher = {International Union of Crystallography}, address = {Chester}, issn = {0909-0495}, doi = {10.1107/S1600577518001662}, pages = {537 -- 542}, year = {2018}, abstract = {The effects of varying LiPF6 salt concentration and the presence of lithium bis(oxalate)borate additive on the electronic structure of commonly used lithium-ion battery electrolyte solvents (ethylene carbonate-dimethyl carbonate and propylene carbonate) have been investigated.

Carbon and oxygen K-edges provide characteristic information on the electronic structure of the electrolyte solutions, which are sensitive to local chemistry. Higher Li+ ion concentration in the solvent manifests itself as a blue-shift of both the pi* feature in the carbon edge and the carbonyl pi* feature in the oxygen edge. While these oxygen K-edge results agree with previous soft X-ray absorption studies on LiBF4 salt concentration in propylene carbonate, carbon K-edge spectra reveal a shift in energy, which can be explained with differing ionic conductivities of the electrolyte solutions.}, language = {en} } @article{Wilke2018, author = {Wilke, Max}, title = {X-Ray Absorption Spectroscopy Measurements}, series = {Magmas Under Pressure : Advances in High-Pressure Experiments on Structure and Properties of Melts}, journal = {Magmas Under Pressure : Advances in High-Pressure Experiments on Structure and Properties of Melts}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {978-0-12-811274-8}, doi = {10.1016/B978-0-12-811301-1.00006-X}, pages = {155 -- 178}, year = {2018}, abstract = {An overview is given on the current state of X-ray absorption measurements on silicate melts and glasses.

The canalization hypothesis proposes that the auxin feedback on its polar flow is a crucial, plant-specific mechanism mediating multiple self-organizing developmental processes. Here, we used the auxin effect on the PIN polar localization in Arabidopsis thaliana roots as a proxy for the auxin feedback on the PIN polarity during canalization. We performed microarray experiments to find regulators of this process that act downstream of auxin. We identified genes that were transcriptionally regulated by auxin in an AXR3/IAA17-and ARF7/ARF19-dependent manner. Besides the known components of the PIN polarity, such as PID and PIP5K kinases, a number of potential new regulators were detected, among which the WRKY23 transcription factor, which was characterized in more detail. Gain-and loss-of-function mutants confirmed a role for WRKY23 in mediating the auxin effect on the PIN polarity. Accordingly, processes requiring auxin-mediated PIN polarity rearrangements, such as vascular tissue development during leaf venation, showed a higher WRKY23 expression and required the WRKY23 activity. Our results provide initial insights into the auxin transcriptional network acting upstream of PIN polarization and, potentially, canalization-mediated plant development.}, language = {en} } @article{ZhouWangShuetal.2018, author = {Zhou, Wei and Wang, Aiping and Shu, Hua and Kliegl, Reinhold and Yan, Ming}, title = {Word segmentation by alternating colors facilitates eye guidance in Chinese reading}, series = {Memory \& cognition}, volume = {46}, journal = {Memory \& cognition}, number = {5}, publisher = {Springer}, address = {New York}, issn = {0090-502X}, doi = {10.3758/s13421-018-0797-5}, pages = {729 -- 740}, year = {2018}, abstract = {During sentence reading, low spatial frequency information afforded by spaces between words is the primary factor for eye guidance in spaced writing systems, whereas saccade generation for unspaced writing systems is less clear and under debate. In the present study, we investigated whether word-boundary information, provided by alternating colors (consistent or inconsistent with word-boundary information) influences saccade-target selection in Chinese. In Experiment 1, as compared to a baseline (i.e., uniform color) condition, word segmentation with alternating color shifted fixation location towards the center of words. In contrast, incorrect word segmentation shifted fixation location towards the beginning of words. In Experiment 2, we used a gaze-contingent paradigm to restrict the color manipulation only to the upcoming parafoveal words and replicated the results, including fixation location effects, as observed in Experiment 1. These results indicate that Chinese readers are capable of making use of parafoveal word-boundary knowledge for saccade generation, even if such information is unfamiliar to them. The present study provides novel support for the hypothesis that word segmentation is involved in the decision about where to fixate next during Chinese reading.}, language = {en} } @article{GarciaDeryRoeseretal.2018, author = {Garcia, Rowena and Dery, Jeruen E. and Roeser, Jens and H{\"o}hle, Barbara}, title = {Word order preferences of Tagalog-speaking adults and children}, series = {First language}, volume = {38}, journal = {First language}, number = {6}, publisher = {Sage Publ.}, address = {London}, issn = {0142-7237}, doi = {10.1177/0142723718790317}, pages = {617 -- 640}, year = {2018}, abstract = {This article investigates the word order preferences of Tagalog-speaking adults and five- and seven-year-old children.

Adults preferred agent-initial constructions in the patient voice but not in the agent voice, while the children produced mainly agent-initial constructions regardless of voice. This agent-initial preference, despite the lack of a close link between the agent and the subject in Tagalog, shows that this word order preference is not merely syntactically-driven (subject-initial preference). Additionally, the children's agent-initial preference in the agent voice, contrary to the adults' lack of preference, shows that children do not respect the subject-last principle of ordering Tagalog full noun phrases. These results suggest that language-specific optional features like a subject-last principle take longer to be acquired.}, language = {en} } @article{SauermannHoehle2018, author = {Sauermann, Antje and H{\"o}hle, Barbara}, title = {Word order in German child language and child-directed speech}, series = {Glossa: A Journal of General Linguistics}, volume = {3}, journal = {Glossa: A Journal of General Linguistics}, number = {1}, publisher = {Ubiquity Press LTD}, address = {London}, issn = {2397-1835}, doi = {10.5334/gjgl.281}, pages = {32}, year = {2018}, abstract = {We report two corpus analyses to examine the impact of animacy, definiteness, givenness and type of referring expression on the ordering of double objects in the spontaneous speech of German-speaking two- to four-year-old children and the child-directed speech of their mothers. The first corpus analysis revealed that definiteness, givenness and type of referring expression influenced word order variation in child language and child-directed speech when the type of referring expression distinguished between pronouns and lexical noun phrases. These results correspond to previous child language studies in English (e.g., de Marneffe et al. 2012). Extending the scope of previous studies, our second corpus analysis examined the role of different pronoun types on word order. It revealed that word order in child language and child-directed speech was predictable from the types of pronouns used. Different types of pronouns were associated with different sentence positions but also showed a strong correlation to givenness and definiteness. Yet, the distinction between pronoun types diminished the effects of givenness so that givenness had an independent impact on word order only in child-directed speech but not in child language. Our results support a multi-factorial approach to word order in German. Moreover, they underline the strong impact of the type of referring expression on word order and suggest that it plays a crucial role in the acquisition of the factors influencing word order variation.}, language = {en} }
