Fossil evidence supports an African origin, and suggests that leopards were already present in Eurasia during the Early Pleistocene. Analysis of DNA sequences however, suggests a more recent, Middle Pleistocene shared ancestry of Asian and African leopards. These contrasting patterns led researchers to propose a two-stage hypothesis of leopard dispersal out of Africa: an initial Early Pleistocene colonisation of Asia and a subsequent replacement by a second colonisation wave during the Middle Pleistocene. The status of Late Pleistocene European leopards within this scenario is unclear: were these populations remnants of the first dispersal, or do the last surviving European leopards share more recent ancestry with their African counterparts? Results In this study, we generate and analyse mitogenome sequences from historical samples that span the entire modern leopard distribution, as well as from Late Pleistocene remains. We find a deep bifurcation between African and Eurasian mitochondrial lineages (~ 710 Ka), with the European ancient samples as sister to all Asian lineages (~ 483 Ka). The modern and historical mainland Asian lineages share a relatively recent common ancestor (~ 122 Ka), and we find one Javan sample nested within these. Conclusions The phylogenetic placement of the ancient European leopard as sister group to Asian leopards suggests that these populations originate from the same out-of-Africa dispersal which founded the Asian lineages. The coalescence time found for the mitochondrial lineages aligns well with the earliest undisputed fossils in Eurasia, and thus encourages a re-evaluation of the identification of the much older putative leopard fossils from the region. The relatively recent ancestry of all mainland Asian leopard lineages suggests that these populations underwent a severe population bottleneck during the Pleistocene. Finally, although only based on a single sample, the unexpected phylogenetic placement of the Javan leopard could be interpreted as evidence for exchange of mitochondrial lineages between Java and mainland Asia, calling for further investigation into the evolutionary history of this subspecies.}, language = {en} } @misc{MuellerStollMuelleretal.2019, author = {Mueller, Juliane and Stoll, Josefine and Mueller, Steffen and Mayer, Frank}, title = {Dose-response relationship of core-specific sensorimotor interventions in healthy, welltrained participants}, series = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, number = {499}, issn = {1866-8364}, doi = {10.25932/publishup-42241}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-422414}, year = {2019}, abstract = {Background: Core-specific sensorimotor exercises are proven to enhance neuromuscular activity of the trunk, improve athletic performance and prevent back pain. However, the dose-response relationship and, therefore, the dose required to improve trunk function is still under debate. The purpose of the present trial will be to compare four different intervention strategies of sensorimotor exercises that will result in improved trunk function. Methods/design: A single-blind, four-armed, randomized controlled trial with a 3-week (home-based) intervention phase and two measurement days pre and post intervention (M1/M2) is designed. Experimental procedures on both measurement days will include evaluation of maximum isokinetic and isometric trunk strength (extension/flexion, rotation) including perturbations, as well as neuromuscular trunk activity while performing strength testing. The primary outcome is trunk strength (peak torque). Neuromuscular activity (amplitude, latencies as a response to perturbation) serves as secondary outcome. The control group will perform a standardized exercise program of four sensorimotor exercises (three sets of 10 repetitions) in each of six training sessions (30 min duration) over 3 weeks. The intervention groups' programs differ in the number of exercises, sets per exercise and, therefore, overall training amount (group I: six sessions, three exercises, two sets; group II: six sessions, two exercises, two sets; group III: six sessions, one exercise, three sets). The intervention programs of groups I, II and III include additional perturbations for all exercises to increase both the difficulty and the efficacy of the exercises performed. Statistical analysis will be performed after examining the underlying assumptions for parametric and non-parametric testing. Discussion: The results of the study will be clinically relevant, not only for researchers but also for (sports) therapists, physicians, coaches, athletes and the general population who have the aim of improving trunk function.}, language = {en} } @book{Wieczorek2019, author = {Wieczorek, Bernhard}, title = {Zivilprozessordnung und Nebengesetze}, series = {Grosskommentare der Praxis}, journal = {Grosskommentare der Praxis}, editor = {Sch{\"u}tze, G{\"o}tz}, edition = {4., neu bearbeitete Auflage}, publisher = {De Gruyter}, address = {Berlin}, isbn = {978-3-11-056609-3}, pages = {XXXI, 818}, year = {2019}, language = {de} } @misc{PeitzBehringerGranacher2019, author = {Peitz, Matti and Behringer, Michael and Granacher, Urs}, title = {A systematic review on the effects of resistance and plyometric training on physical fitness in youth}, series = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, number = {498}, issn = {1866-8364}, doi = {10.25932/publishup-42220}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-422201}, year = {2019}, abstract = {Introduction To date, several meta-analyses clearly demonstrated that resistance and plyometric training are effective to improve physical fitness in children and adolescents. However, a methodological limitation of meta-analyses is that they synthesize results from different studies and hence ignore important differences across studies (i.e., mixing apples and oranges). Therefore, we aimed at examining comparative intervention studies that assessed the effects of age, sex, maturation, and resistance or plyometric training descriptors (e.g., training intensity, volume etc.) on measures of physical fitness while holding other variables constant. Methods To identify relevant studies, we systematically searched multiple electronic databases (e.g., PubMed) from inception to March 2018. We included resistance and plyometric training studies in healthy young athletes and non-athletes aged 6 to 18 years that investigated the effects of moderator variables (e.g., age, maturity, sex, etc.) on components of physical fitness (i.e., muscle strength and power). Results Our systematic literature search revealed a total of 75 eligible resistance and plyometric training studies, including 5,138 participants. Mean duration of resistance and plyometric training programs amounted to 8.9 ± 3.6 weeks and 7.1±1.4 weeks, respectively. Our findings showed that maturation affects plyometric and resistance training outcomes differently, with the former eliciting greater adaptations pre-peak height velocity (PHV) and the latter around- and post-PHV. Sex has no major impact on resistance training related outcomes (e.g., maximal strength, 10 repetition maximum). In terms of plyometric training, around-PHV boys appear to respond with larger performance improvements (e.g., jump height, jump distance) compared with girls. Different types of resistance training (e.g., body weight, free weights) are effective in improving measures of muscle strength (e.g., maximum voluntary contraction) in untrained children and adolescents. Effects of plyometric training in untrained youth primarily follow the principle of training specificity. Despite the fact that only 6 out of 75 comparative studies investigated resistance or plyometric training in trained individuals, positive effects were reported in all 6 studies (e.g., maximum strength and vertical jump height, respectively). Conclusions The present review article identified research gaps (e.g., training descriptors, modern alternative training modalities) that should be addressed in future comparative studies.}, language = {en} } @phdthesis{Hoffmann2019, author = {Hoffmann, Mathias}, title = {Improving measurement and modelling approaches of the closed chamber method to better assess dynamics and drivers of carbon based greenhouse gas emissions}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-421302}, school = {Universit{\"a}t Potsdam}, pages = {xx, 204, xxix}, year = {2019}, abstract = {The trace gases CO2 and CH4 pertain to the most relevant greenhouse gases and are important exchange fluxes of the global carbon (C) cycle. Their atmospheric quantity increased significantly as a result of the intensification of anthropogenic activities, such as especially land-use and land-use change, since the mid of the 18th century. To mitigate global climate change and ensure food security, land-use systems need to be developed, which favor reduced trace gas emissions and a sustainable soil carbon management. This requires the accurate and precise quantification of the influence of land-use and land-use change on CO2 and CH4 emissions. A common method to determine the trace gas dynamics and C sink or source function of a particular ecosystem is the closed chamber method. This method is often used assuming that accuracy and precision are high enough to determine differences in C gas emissions for e.g., treatment comparisons or different ecosystem components. However, the broad range of different chamber designs, related operational procedures and data-processing strategies which are described in the scientific literature contribute to the overall uncertainty of closed chamber-based emission estimates. Hence, the outcomes of meta-analyses are limited, since these methodical differences hamper the comparability between studies. Thus, a standardization of closed chamber data acquisition and processing is much-needed. Within this thesis, a set of case studies were performed to: (I) develop standardized routines for an unbiased data acquisition and processing, with the aim of providing traceable, reproducible and comparable closed chamber based C emission estimates; (II) validate those routines by comparing C emissions derived using closed chambers with independent C emission estimates; and (III) reveal processes driving the spatio-temporal dynamics of C emissions by developing (data processing based) flux separation approaches. The case studies showed: (I) the importance to test chamber designs under field conditions for an appropriate sealing integrity and to ensure an unbiased flux measurement. Compared to the sealing integrity, the use of a pressure vent and fan was of minor importance, affecting mainly measurement precision; (II) that the developed standardized data processing routines proved to be a powerful and flexible tool to estimate C gas emissions and that this tool can be successfully applied on a broad range of flux data sets from very different ecosystem; (III) that automatic chamber measurements display temporal dynamics of CO2 and CH4 fluxes very well and most importantly, that they accurately detect small-scale spatial differences in the development of soil C when validated against repeated soil inventories; and (IV) that a simple algorithm to separate CH4 fluxes into ebullition and diffusion improves the identification of environmental drivers, which allows for an accurate gap-filling of measured CH4 fluxes. Overall, the proposed standardized data acquisition and processing routines strongly improved the detection accuracy and precision of source/sink patterns of gaseous C emissions. Hence, future studies, which consider the recommended improvements, will deliver valuable new data and insights to broaden our understanding of spatio-temporal C gas dynamics, their particular environmental drivers and underlying processes.}, language = {en} } @phdthesis{Muelling2019, author = {M{\"u}lling, Eric}, title = {Big Data und der digitale Ungehorsam}, publisher = {Springer VS}, address = {Wiesbaden}, isbn = {978-3-658-24158-2}, pages = {XV, 242}, year = {2019}, language = {de} } @incollection{HickmannPartzschPattbergetal.2019, author = {Hickmann, Thomas and Partzsch, Lena and Pattberg, Philipp H. and Weiland, Sabine}, title = {Conclusion}, series = {The anthropocene debate and political science}, booktitle = {The anthropocene debate and political science}, publisher = {Routledge}, address = {London}, isbn = {978-0-8153-8614-8}, publisher = {Universit{\"a}t Potsdam}, pages = {237 -- 251}, year = {2019}, language = {en} } @book{OPUS4-42120, title = {The anthropocene debate and political science}, series = {Routledge research in global environmental governance}, journal = {Routledge research in global environmental governance}, editor = {Hickmann, Thomas and Partzsch, Lena and Pattberg, Philipp H. and Weiland, Sabine}, publisher = {Routledge}, address = {London}, isbn = {978-0-8153-8614-8}, publisher = {Universit{\"a}t Potsdam}, pages = {260}, year = {2019}, abstract = {Anthropocene has become an environmental buzzword. It denotes a new geological epoch that is human?dominated. As mounting scientific evidence reveals, humankind has fundamentally altered atmospheric, geological, hydrological, biospheric, and other Earth system processes to an extent that the risk of an irreversible system change emerges. Human societies must therefore change direction and navigate away from critical tipping points in the various ecosystems of our planet. This hypothesis has kicked off a debate not only on the geoscientific definition of the Anthropocene era, but increasingly also in the social sciences. However, the specific contribution of the social sciences disciplines and in particular that of political science still needs to be fully established. This edited volume analyzes, from a political science perspective, the wider social dynamics underlying the ecological and geological changes, as well as their implications for governance and politics in the Anthropocene. The focus is on two questions: (1) What is the contribution of political science to the Anthropocene debate, e.g. in terms of identified problems, answers, and solutions? (2) What are the conceptual and practical implications of the Anthropocene debate for the discipline of political science? Overall, this book contributes to the Anthropocene debate by providing novel theoretical and conceptual accounts of the Anthropocene, engaging with contemporary politics and policy-making in the Anthropocene, and offering a critical reflection on the Anthropocene debate as such. The volume will be of great interest to students and scholars of political science, global environmental politics and governance, and sustainable development.}, language = {en} }
