Abstract

An increasing population faces the growing demand for agricultural products and accurate global climate models that account for individual plant morphologies to predict favorable human habitat. Both demands are rooted in an improved understanding of the mechanistic origins of plant development. Such understanding requires geometric and topological descriptors to characterize the phenotype of plants and its link to genotypes. However, the current plant phenotyping framework relies on simple length and diameter measurements, which fail to capture the exquisite architecture of plants. The Research Topic “Morphological Plant Modeling: Unleashing Geometric and Topological Potential within the Plant Sciences” is the result of a workshop held at National Institute for Mathematical and Biological Synthesis (NIMBioS) in Knoxville, Tennessee. From 2.-4. September 2015 over 40 scientists from mathematics, computer science, engineering, physics and biology came together to set new frontiers in combining plant phenotyping with recent results from shape theory at the interface of geometry and topology. In doing so, the Research Topic synthesizes the views from multiple disciplines to reveal the potential of new mathematical concepts to analyze and quantify the relationship between morphological plant features. As such, the Research Topic bundles examples of new mathematical techniques including persistent homology, graph-theory, and shape statistics to tackle questions in crop breeding, developmental biology, and vegetation modeling. The challenge to model plant morphology under field conditions is a central theme of the included papers to address the problems of climate change and food security, that require the integration of plant biology and mathematics from geometry and topology research applied to imaging and simulation techniques. The introductory white paper written by the workshop participants identifies future directions in research, education and policy making to integrate biological and mathematical approaches and to strengthen research at the interface of both disciplines.

Abstract

This collection of papers on phrasal compounding is part of a bigger project whose aims are twofold: First, it seeks to broaden the typological perspective by providing data for as many different languages as possible to gain a better understanding of the phenomenon itself. Second, based on these data which clearly show interaction between syntax and morphology it aims to discuss theoretical models which deal with this kind of interaction in different ways. Models like Generative Grammar assume components of grammar and a clear-cut distinction between the lexicon (often including morphology) and grammar. Other models, like construction grammar, do not assume such components and are rather based on a lexicon including constructs. A comparison of these models on the basis of this phenomenon on the morphology-syntax interface makes it possible to assess their descriptive and explanatory power.

Abstract

This book presents a synchronic grammar of the southern dialects of Yauyos, an extremely endangered Quechuan language spoken in the Peruvian Andes. As the language is highly synthetic, the grammar focuses principally on morphology; a longer section is dedicated to the language's unusual evidential system. The grammar's 1400 examples are drawn from a 24-hour corpus of transcribed recordings collected in the course of the documentation of the language.

Abstract

Recent years have seen an upsurge of interest in the notion of salience in linguistics and related disciplines. While in top-down salience, perceivers endogenously direct their attention to a certain stimulus, in the bottom-up salience, it is the stimulus itself which attracts attention. In prototypical cases of bottom-up salience, the stimulus stands out because it is incongruous with a given ground by virtue of intrinsic physical characteristics. But a stimulus may also cause surprise by virtue of deviating from a cognitive ground, e.g., when violating social or probabilistic expectations. This has prompted researchers to examine the relationship between expectations and the perceptual salience of linguistic stimuli in new ways. This e-book features contributions from different scientific frameworks. The reader will find commentaries, reviews, and original research articles on models of sociolinguistic and morphological salience, the role of attention, affect, and predictability, and on how salient items are processed, categorized and learned. Taken together, the articles in this volume contribute to our understanding of how the perceptual salience of linguistic forms and variants can be theoretically framed and methodologically operationalized in different areas of linguistic processing.

Abstract

In June 2015 we held a workshop on the beautiful island of Mallorca, Spain with a focus on sea level variability and change. Over 120 sea level experts from around the world attended this workshop, from a range of different disciplines. The main aims of the workshop were to: 1.) Evaluate the current state-of-knowledge of sea level science; 2.) Identify gaps and unresolved questions in any aspect of sea level science; and 3.) Design future research to address these issue. All aspects of sea level changes were covered, from global to regional, observations and modelling, processes driving mean sea level changes and extremes, from the geological scale to the instrumental era and future projections and including impacts on the coastal zones. This E-Book presents papers that came out of that workshop. Overall, these papers illustrate the multi-disciplinary nature of sea level research, cross-cutting many fields of research including: oceanography, meteorology, geology, coastal morphodynamics, engineering and the social-economic aspects. Collectively, theses articles represent an interesting range of perspectives and original studies that contribute to understanding the dynamic nature of sea level and its impacts across a wide range of time and space scales. Enjoy reading them!

Abstract

This collection attempts to integrate work pertaining to a fundamental question in plant evolution: What are the molecular underpinnings for the origin of different plant forms? Among the many facets this question touches are the transition to land, the emergence of vascular plants, the origin of the seed and the origin and diversification of floral form. We aim to bring to the forefront the most salient and original plant systems and approaches within an inclusive phylogenetic context that encompasses representatives of the major lineages of land plants.
