From a Late Quaternary permafrost sediment core from the Buor Khaya Peninsula, we analysed plant-derived sedimentary ancient DNA (sedaDNA) to identify the taxonomic composition of plant organic matter, and undertook palynological analysis to assess the environmental conditions during deposition. Using sedaDNA, we identified 154 taxa and from pollen and non-pollen palynomorphs we identified 83 taxa. In the deposits dated between 54 and 51 kyr BP, sedaDNA records a diverse low-centred polygon plant community including recurring aquatic pond vegetation while from the pollen record we infer terrestrial open-land vegetation with relatively dry environmental conditions at a regional scale. A fluctuating dominance of either terrestrial or swamp and aquatic taxa in both proxies allowed the local hydrological development of the polygon to be traced. In deposits dated between 11.4 and 9.7 kyr BP (13.4-11.1 cal kyr BP), sedaDNA shows a taxonomic turnover to moist shrub tundra and a lower taxonomic richness compared to the older samples. Pollen also records a shrub tundra community, mostly seen as changes in relative proportions of the most dominant taxa, while a decrease in taxonomic richness was less pronounced compared to sedaDNA. Our results show the advantages of using sedaDNA in combination with palynological analyses when macrofossils are rarely preserved. The high resolution of the sedaDNA record provides a detailed picture of the taxonomic composition of plant-derived organic matter throughout the core, and palynological analyses prove valuable by allowing for inferences of regional environmental conditions.}, language = {en} } @article{ZimmermannStoofLeichsenringKruseetal.2020, author = {Zimmermann, Heike Hildegard and Stoof-Leichsenring, Kathleen Rosemarie and Kruse, Stefan and M{\"u}ller, Juliane and Stein, Ruediger and Tiedemann, Ralf and Herzschuh, Ulrike}, title = {Changes in the composition of marine and sea-ice diatoms derived from sedimentary ancient DNA of the eastern Fram Strait over the past 30 000 years}, series = {Ocean science}, volume = {16}, journal = {Ocean science}, number = {5}, publisher = {Copernicus}, address = {G{\"o}ttingen}, issn = {1812-0784}, doi = {10.5194/os-16-1017-2020}, pages = {1017 -- 1032}, year = {2020}, abstract = {The Fram Strait is an area with a relatively low and irregular distribution of diatom microfossils in surface sediments, and thus microfossil records are scarce, rarely exceed the Holocene, and contain sparse information about past richness and taxonomic composition.

The sequences were assigned to diatoms that are common in the area and characteristic of cold water. SedaDNA allowed us to observe shifts of potential lineages from species of the genus Chaetoceros that can be related to different climatic phases, suggesting that pre-adapted ecotypes might have played a role in the long-term success of species in areas of changing environmental conditions. These sedaDNA results complement our understanding of the long-term history of diatom assemblages and their general relationship to environmental conditions of the past. Sea-ice diatoms (Pauliella taeniata [Grunow] Round \& Basson, Attheya septentrionalis [ostrup] R. M. Crawford and Nitzschia frigida [Grunow]) detected during the late glacial and Younger Dryas are in agreement with previous sea-ice reconstructions. A positive correlation between pennate diatom richness and the sea-ice proxy IP25 suggests that sea ice fosters pennate diatom richness, whereas a negative correlation with June insolation and temperature points to unfavorable conditions during the Holocene. A sharp increase in proportions of freshwater diatoms at similar to 11.1 cal kyr BP implies the influence of terrestrial runoff and coincides with the loss of 42\% of diatom sequence variants.

The alternatives are determined by focus in the case of aspectual schon (Krifka 2000), but are restricted to the polar alternatives p and ¬p in the case of modal schon. Semantically, modal schon introduces a presupposition to the effect that the circumstantial conversational background contains more factual evidence in favor of p than in favor of ¬p⁠, thereby making modal schon the not at-issue counterpart of the overt comparative form eher 'rather' (Herburger \& Rubinstein 2014).

The feature specification of Num as [+lattice] or [-lattice] is responsible for whether the DP denotes into the domain of atomic or mass/plural entities, respectively. In the case of complex PQEs, the syntactic Num-head hosts the overt element een 'a, one', which carries a [-lattice] feature, thus ensuring that the PQE ranges exclusively over the domain of atomic entities, but not mass or plural entities. The Num-head een differs from its simplex counterpart wat 'something', which is analyzed as an NP-proform with an underspecified [lattice]-feature. As a result, wat can range over atomic and mass domains alike. In the final part of the article, it is argued that wat is also underspecified for the operator feature [rel/wh], for which reason it can also function as an interrogative expression (what) and as a relative pronoun (which), respectively, depending on the syntactic context. Throughout the article, the Low German data are compared with relevant data from other German dialects and Germanic and Romance languages, pointing out similarities and differences in the syntactic structure and feature content of PQEs across these languages and dialects.}, language = {en} } @article{Zimmermann2011, author = {Zimmermann, Malte}, title = {The grammatical expression of focus in West Chadic variation and uniformity in and across languages}, series = {Linguistics : an interdisciplinary journal of the language sciences}, volume = {49}, journal = {Linguistics : an interdisciplinary journal of the language sciences}, number = {5}, publisher = {De Gruyter Mouton}, address = {Berlin}, issn = {0024-3949}, doi = {10.1515/LING.2011.032}, pages = {1163 -- 1213}, year = {2011}, abstract = {The article provides an overview of the grammatical realization of focus in four West Chadic languages (Chadic, Afro-Asiatic). The languages discussed exhibit an intriguing crosslinguistic variation in the realization of focus, both among themselves as well as compared to European intonation languages. They also display language-internal variation in the formal realization of focus. The West Chadic languages differ widely in their ways of expressing focus, which range from syntactic over prosodic to morphological devices. In contrast to European intonation languages, the focus marking systems of the West Chadic languages are inconsistent in that focus is often not grammatically expressed, but these inconsistencies are shown to be systematic. Subject foci (contrastive or not) and contrastive nonsubject foci are always grammatically marked, whereas information focus on nonsubjects need not be marked as such. The absence of formal focus marking supports pragmatic theories of focus in terms of contextual resolution. The special status of focused subjects and contrastive foci is derived from the Contrastive Focus Hypothesis, which requires unexpected foci and unexpected focus contents to be marked as such, together with the assumption that canonical subjects in West Chadic receive a default interpretation as topics. Finally, I discuss certain focus ambiguities which are not attested in intonation languages, nor do they follow on standard accounts of focus marking, but which can be accounted for in terms of constraint interaction in the formal expression of focus.}, language = {en} } @article{Zimmermann2016, author = {Zimmermann, Malte}, title = {Predicate focus}, series = {The Oxford handbook of information structure}, journal = {The Oxford handbook of information structure}, publisher = {Oxford University Press}, address = {Oxford}, isbn = {978-0-19-964267-0}, pages = {314 -- 335}, year = {2016}, language = {en} } @article{ZimmermannDeVeaughGeissToennisetal.2020, author = {Zimmermann, Malte and De Veaugh-Geiss, Joseph P. and T{\"o}nnis, Swantje and Onea, Edgar}, title = {(Non-)exhaustivity in focus partitioning across languages}, series = {Approaches to Hungarian}, volume = {16}, journal = {Approaches to Hungarian}, publisher = {John Benjamins}, address = {Amsterdam}, pages = {24}, year = {2020}, abstract = {We present novel experimental evidence on the availability and the status of exhaustivity inferences with focus partitioning in German, English, and Hungarian.

Crucially, there does not seem to be a one-to-one mapping between particular formal features (focus marking devices) and focus, neither from a cross-linguistic perspective, nor within individual languages. This raises the question of what is actually being expressed if we say that a constituent is focused in a particular language, and whether, or to what extent, the same semantic or pragmatic content is formally expressed by focus-marking across languages. This special issue addresses the question of focus and its grammatical realization from a number of theoretical and empirical perspectives. In this introductory article we elaborate on this question by making an explicit proposal about what we take to be the correct way of thinking about the information-structural category of focus and its formal realization. In the first part, we introduce a unified semantico-pragmatic perspective on focus in terms of alternatives and possible worlds. In the second part, we present a cursory cross-linguistic overview of focus marking strategies as found in the languages of the world. Finally, in the third part, we discuss the connection between the notion of focus, different pragmatic uses of focus and different focus marking strategies employed in the grammars of natural languages.

This research presents a three-step synthesis of coloring agents, capable of adhering onto synthetic polypropylene yarns without harsh energy-consuming conditions. This is possible by encapsulation of organic pigments using trimethoxyphenylsilane, introduction of surface double bonds via modification of the silica shell with trimethoxysilylpropylmethacrylate and final attachment of highly adhesive anchor peptides using thiol-ene chemistry.

In this context, NBS projects should benefit from strong collaborative governance models, and the European Union is facilitating and encouraging such models.
