Preserving biodiverse river corridors for sustainable city development
No full textAs the global population continues to soar and the number of inhabitants in cities climbs ever higher, sustainable development strategies are urgently needed to prevent catastrophic ecological decline in our urban environments. Understanding anthropogenic threats is the first step towards conservation: Jochen Hack, Professor of Ecological Engineering at the University of Darmstadt in Germany and leader of the interdisciplinary research group SEE-URBAN-WATER, utilises habitat quality assessment software to model the effects of urban infrastructure and pollution on the Pochote river’s ecosystem ecology in Nicaragua, Central America
Gene loss and lineage specific restriction-modification systems associated with niche differentiation in the Campylobacter jejuni Sequence Type 403 clonal complex
No full textCampylobacter jejuni is a highly diverse species of bacteria commonly associated with infectious intestinal disease of humans and zoonotic carriage in poultry, cattle, pigs, and other animals. The species contains a large number of distinct clonal complexes that vary from host generalist lineages commonly found in poultry, livestock, and human disease cases to host-adapted specialized lineages primarily associated with livestock or poultry. Here, we present novel data on the ST403 clonal complex of C. jejuni, a lineage that has not been reported in avian hosts. Our data show that the lineage exhibits a distinctive pattern of intralineage recombination that is accompanied by the presence of lineage-specific restriction-modification systems. Furthermore, we show that the ST403 complex has undergone gene decay at a number of loci. Our data provide a putative link between the lack of association with avian hosts of C. jejuni ST403 and both gene gain and gene loss through nonsense mutations in coding sequences of genes, resulting in pseudogene formation
Die Römische Republik /
No full textWer sich für antike Geschichte interessiert, greift zu dieser knappen und gut lesbaren Geschichte der Römischen Republik, geschrieben von einem der bekanntesten Althistoriker Deutschlands. Jochen Bleicken (1926-2005) führt den Leser von der Zeit der Etrusker bis zum Ende der Republik, das die Herrschaft Caesars besiegelte. Alle wichtigen Phasen der republikanischen Geschichte entfalten sich: die Ständekämpfe, Aufstieg Roms zur Weltherrschaft - und die zugehörigen ungeheuren kriegerischen Auseinandersetzungen -, Ursachen und Beginn der inneren Krise seit den Gracchen, die Restauration unter Sulla und schließlich: die Auflösung der Republik und die Begründung der Monarchie.

Bewertung der integralen Wiederherstellung eines städtischen tropischen Wassereinzugsgebiets durch Entwicklung und Modellierung von Szenarien für nachrüstbare multifunktionale naturbasierte Lösungen
No full textUnplanned urban expansion in Latin America has significantly disrupted the natural hydrological processes of watersheds, particularly in tropical regions with extreme climatic conditions. This has led to substantial volumes of runoff, increasing the risk of flooding and necessitating large-scale engineering interventions to mitigate damage. Urbanization has not only exacerbated flooding issues but has also diminished green recreational spaces for residents and caused ecological degradation, negatively impacting the health of watersheds.
This doctoral thesis presents a methodology aimed at improving the health of an urban tropical watershed in the search of its integral recovery, by creating scenarios for the implementation of multifunctional and retrofitted Nature-based Solutions (NbS). Those NbS scenarios utilize available spaces for NbS and consider existing land cover, complemented with insights from a co-design process of a Real-World Lab leveraging the multifunctionality of NbS to achieve hydrological, ecological, and social benefits, addressing the vulnerabilities of an urban tropical watershed. The case study focuses on an urban watershed located in Costa Rica's Greater Metropolitan Area (GAM), covering 23 km², with approximately 66% of its surface area impermeable.
The proposed scenarios include using public roads in residential areas for the implementation of permeable pavements, bioretention cells, infiltration trenches, and street planters, while in industrial areas, suitable rooftops and parking lots are converted into green roofs and permeable pavements. Additionally, various public green spaces are transformed into multifunctional storage areas. Hydrological and hydraulic models were used to assess the performance of each scenario, while the increase in green space served as an indicator of ecological and social benefits. The simultaneous implementation of residential, industrial, and green space scenarios provides available surface area for NbS, potentially leading to a reduction in peak flow and runoff volume during specific precipitation events.
Given that unregulated urban growth is a common feature of most urban watersheds in Latin America, this methodology, based on a co-design process and the use of different land cover types to create multifunctional retrofitted NbS scenarios; is transferable and adaptable to other tropical urban watersheds, as long as the local conditions of new study cases are taken into account
Analysis, interpretation, and the local dimension of economic transformation: What went wrong and why?
No full textTransformation has been put in motion by a variety of both endogenous and exogenous forces. Although not any process was under the control of those countries, their choice of goals and instruments was anyway particularly great, at least theoretically. However, transformation was implemented as a rather narrowly defined and technically circumscribed problem-solving process aiming at applying sound general principles of economics and management to reach well-defined goals. It turned out to generate new problems and resulted in different outcomes in different countries and, within individual countries, in different territories. This paper treats transformation as innovation and considers that it had to deal with different dimensions, including both general principles and local features, opportunities, and constraints, and both analysis based on problem-solving, and interpretation of the new situation. These dimensions should have been managed simultaneously, but failed to do so. The paper provides a general explanation for the failure in managing simultaneously the various components of transformation and considers what the 2008 international crisis has revealed of the implementation of 20 years of transformation.Transformation, Local development, Reform, Analysis, Interpretation, Crisis, Washington Consensus, Innovation
