In his polemical essay, the author defines these as historicism, the legalistic bias, the underestimation of non-state actors and the overestimation of the state as such. Discussing the linkage between loyality, ethnicy, and politics, he strongly argues for recognition of the fact that the world is groping for new political arrangements for which we simply do not have the appropriate ideas or words to describe. In the future, the range of political identities and loyalities in the global culture of "fragmegration" will extend beyond traditional multiculturalism.

The enzyme catalyzed the penultimate step of juvenile hormone biosynthesis in the insects. Culturing corpora allata in the presence of sinefungin greatly suppressed juvenile hormone production. The following in vivo effects were visible after injection of the inhibitor: increase in mortality and reduction of total haemolymph protein liter and ovary fresh weight, as well as length of terminal oocytes. Attempts to reverse these effects by topical application of the juvenile hormone analog ZR-515 (methoprene) were only partly successful. Therefore, the in vivo effects may be due to a general inhibition of methyltransferase enzymes in the insect. Sinefungin appeared to be of potential interest as the first representative of a new class of insect growth regulators.

T1 - The inhibitory effect of sinefungin on juvenile hormone biosynthesis and development in locusts N2 - The antibiotic fungal metabolite sinefungin is a potent inhibitor of S-adenosylmethionine-acceptor methyltransferases. Its effect on insect metabolism and especially on corpora allata farnesoic acid methyltransferase, which catalyzes the penultimate step of juvenile hormone biosynthesis, was investigated in Locusta migratoria. Injection of sinefungin results in a delay of imaginal molt and in suppression of ovary development. Isolated corpora allata are unable to synthesize juvenile hormone III in the presence of more than 1.0 mM sinefungin. In a cell-free system containing the S-adenosylmethionine-dependent farnesoic acid methyltransferase from corpora allata sinefungin is a competitive inhibitor of the synthesis of methylfarnesoate with Ki of 1 μM.

In this study, we identify and quantify the ENSO contribution to the eastern African rainfall variability to forecast future eastern African vegetation response to rainfall variability related to a predicted intensified ENSO. To differentiate the vegetation variability due to ENSO, we removed the ENSO signal from the climate data using empirical orthogonal teleconnection (EOT) analysis. Then, we simulated the ecosystem carbon and water fluxes under the historical climate without components related to ENSO teleconnections. We found ENSO-driven patterns in vegetation response and confirmed that EOT analysis can successfully produce coupled tropical Pacific sea surface temperature-eastern African rainfall teleconnection from observed datasets. We further simulated eastern African vegetation response under future climate change as it is projected by climate models and under future climate change combined with a predicted increased ENSO intensity. Our EOT analysis highlights that climate simulations are still not good at capturing rainfall variability due to ENSO, and as we show here the future vegetation would be different from what is simulated under these climate model outputs lacking accurate ENSO contribution. We simulated considerable differences in eastern African vegetation growth under the influence of an intensified ENSO regime which will bring further environmental stress to a region with a reduced capacity to adapt effects of global climate change and food security.

Ein Studium seiner Gegenwart und seiner Zukunft wiederum hilft uns dabei, die global bedeutende Artenvielfalt und die ökosystemaren Dienstleistungen Ostafrikas zu schützen. Eine zentrale Rolle spielt dabei spielt die ostafrikanische Vegetation, deren Dynamiken in dieser Dissertation durch Computersimulationen quantifiziert werden sollen. Über Computersimulationen lassen sich frühere Rahmenbedingungen reproduzieren, Voraussagen treffen oder Simulationsexperimente durchführen, die durch Feldforschung nicht möglich wären. Zuallererst muss jedoch ihre Leistungsfähigkeit überprüft werden. Die von dem Modell anhand der heutigen Inputs gelieferten Ergebnisse stimmten weitgehend mit heutigen Beobachtungen ostafrikanischer Vegetation überein. Als nächstes wurde die frühere Vegetation simuliert, für die fossile Pollen-Daten zum Abgleich vorliegen. Über Computermodelle lassen sich Wissenslücken zwischen Standorten überbrücken, bei denen wir über fossile Pollen-Daten verfügen, sodass ein vollständigeres Bild der Vergangenheit entsteht. Zusätzlich validiert wurde die Leistungsfähigkeit des Modells durch die hohe Übereinstimmung zwischen Modell und Pollen-Daten, wo sie im Raum überlappen. Nachdem das Modell getestet und für die Region validiert war, konnte eine der seit langem offenen Fragen über die ostafrikanische Vegetation angegangen werden, nämlich wie Ostafrika seines Tropenwaldes verlustig gehen konnte. In den Tropen wird die heutige Vegetation weltweit hauptsächlich von Wäldern dominiert, mit Ausnahme der Tropengebiete Ostafrikas, wo Wälder nur noch stellenweise an der Küste und im Hochland vorkommen. Durch eine Reihe von Simulationsexperimenten konnte aufgezeigt werden, unter welchen Bedingungen jene Waldgebiete früher zusammenhingen und schließlich fragmentiert wurden. Die Studie hat erwiesen, wie empfindlich die ostafrikanische Vegetation für die Klimaschwankungen ist, die durch den künftigen Klimawandel zu erwarten sind. Weitere Auswirkungen auf das ostafrikanische Klima ergeben sich aus dem El Niño/Southern Oscillation-Phänomen (ENSO), das aus Temperaturfluktuationen zwischen dem Ozean und der Atmosphäre herrührt und künftig an Intensität zunehmen dürfte. Die derzeitigen Klimamodelle sind allerdings noch nicht gut genug beim Erfassen solcher Ereignismuster. In einer Studie wurde der Einfluss des ENSO-Phänomens auf die ostafrikanische Vegetation quantifiziert und dabei aufgezeigt, wie sehr sich die künftige Vegetation von den heute simulierten Ergebnissen unterscheiden könnte, bei denen der genaue ENSO-Beitrag nicht berücksichtigt werden kann. Bei der Berechnung der künftigen weltweiten CO2-Bilanz und den zu treffenden Entscheidungen stellt dies einen zusätzlichen Unsicherheitsfaktor dar. N2 - East Africa is a natural laboratory: Studying its unique geological and biological history can help us better inform our theories and models. Studying its present and future can help us protect its globally important biodiversity and ecosystem services. East African vegetation plays a central role in all these aspects, and this dissertation aims to quantify its dynamics through computer simulations. Computer models help us recreate past settings, forecast into the future or conduct simulation experiments that we cannot otherwise perform in the field. But before all that, one needs to test their performance. The outputs that the model produced using the present day-inputs, agreed well with present-day observations of East African vegetation. Next, I simulated past vegetation for which we have fossil pollen data to compare. With computer models, we can fill the gaps of knowledge between sites where we have fossil pollen data from, and create a more complete picture of the past. Good level of agreement between model and pollen data where they overlapped in space further validated our model performance. Once the model was tested and validated for the region, it became possible to probe one of the long standing questions regarding East African vegetation: How did East Africa lose its tropical forests? The present-day vegetation in the tropics is mainly characterized by continuous forests worldwide except in tropical East Africa, where forests only occur as patches. In a series of simulation experiments, I was able to show under which conditions these forest patches could have been connected and fragmented in the past. This study showed the sensitivity of East African vegetation to climate change and variability such as those expected under future climate change. El Niño Southern Oscillation (ENSO) events that result from the fluctuations in temperature between the ocean and atmosphere, bring further variability to East African climate and are predicted to increase in intensity in the future. But climate models are still not good at capturing the pattens of these events. In a study where I quantified the influence of ENSO events on East African vegetation, I showed how different the future vegetation could be from what we currently predict with these climate models that lack accurate ENSO contribution. Consideration of these discrepancies is important for our future global carbon budget calculations and management decisions.

Although the conjoint occurrence between brain-structural and brain-functional changes, the decrease of plasticity, and changes in cognitive abilities suggests a certain causality between these processes, concrete evidence for the relation between brain development, language processing, and language performance is rare. Therefore, the current dissertation investigates the tripartite relationship between behavior (in the form of language performance and cognitive maturation as prerequisite for language processing), brain structure (in the form of gray matter maturation), and brain function (in the form of brain activation evoked by complex sentence processing). Previous developmental studies indicate a missing increase of activation in accordance to sentence complexity (functional selectivity) in language-relevant brain areas in children. To determine the factors contributing to the functional development of language-relevant brain areas, different methodologies and data acquisition techniques were used to investigate the processing of center-embedded sentences in 5- and 6-year-old children, 7- and 8-year-old children, and adults. Behavioral results indicate that children between 5 and 8 years show difficulties in processing double embedded sentences and that their performance for these type of sentences is positively correlated with digit span. In 7- and 8-year-old children, it was found that especially the processing of long-distance relations between the initial phrase and its corresponding verb appears to be associated with the subject’s verbal working memory capacity. In contrast, children’s performance for double embedded sentences in the younger age group positively correlated with their performance in a standardized sentence comprehension test. This finding supports the hypothesis that processing difficulties in this age group may be mainly attributed to difficulties in processing case marking information. These findings are discussed with respect to current accounts of language and working memory development. A second study aimed at investigating the structural maturation of brain areas involved in sentence comprehension. To do this, whole-brain magnetic resonance images from 59 children between 5 and 8 years were collected and children’s gray matter was analyzed by using voxel-based morphometry. Children’s grammatical proficiency was assessed by a standardized sentence comprehension test. A confirmatory factory analysis corroborated a grammar-relevant and a verbal working memory-relevant factor underlying the measured performance. While children’s ability to assign thematic roles is positively correlated with gray matter probability (GMP) in the left inferior temporal gyrus and the left inferior frontal gyrus, verbal working memory-related performance is positively correlated with GMP in the left parietal operculum extending into the posterior superior temporal gyrus. These areas have been previously shown to be differentially engaged in adults’ complex sentence processing. Thus, the findings of the second study suggest a specific correspondence between children’s GMP in language-relevant brain regions and differential cognitive abilities which underlie complex sentence comprehension. In a third study, functional brain activity during the processing of center-embedded sentences was investigated in three different age groups (5–6 years, 7–8 years, and adults). Although all age groups engage a qualitatively comparable network of the left pars opercularis (PO), the left inferior parietal lobe extending into the posterior superior temporal gyrus (IPL/pSTG), the supplementary motor area (SMA) and the cerebellum, functional selectivity of these regions was only observable in adults. However, functional activation of the language-related regions (PO and IPL/pSTG) predicted sentence comprehension performance for all age groups. To solve the question of the complex interplay between different maturational factors, a fourth study analyzed the predictive power of gray matter probability, verbal working memory capacity, and behavioral differences in performance for simple and complex sentence for the functional selectivity of each activated region. These analyses revealed that the establishment of the adult-like functional selectivity for complex sentences is predicted by a reduction of the left PO’s gray matter probability across age groups while that of the IPL/pSTG is additionally predicted by verbal working memory capacity. Taken all findings together, the current thesis provides evidence that both structural brain maturation and verbal working memory expansion provide the basis for the emergence of functional selectivity in language-related brain regions leading to more efficient sentence processing during development.
