Inferences on the tolerance of some forest woody angiosperms in an urban polluted environment

Urban settings represent some of the most humanly crowded and polluted environments. The genotype effect of five species that show tolerance to urban air pollution in Thessaloniki, Greece was investigated. The study was conducted in pairs of trees that were selected as growing under the same spacing and micro-environment, but showing noticeably different degrees of adaptation to air pollution (‘tolerant’ and ‘sensitive’ trees).

Tree height and leaf morphometric parameters were measured during two consecutive years. Results showed that in at least two species (Populus nigra, Celtis australis) the observed differences were significant between ‘tolerant’ and ‘sensitive’ phenotypes, with ‘tolerant’ trees exhibiting higher growth and larger leaves. It was indicated that the degree of tolerance to urban heavily polluted areas maybe related to both species and genotype, nevertheless this needs further investigation and analysis, especially under controlled environmental conditions.

What Price Flexibility? – The Recent Commission Proposal to Allow for National “Opt-Outs” on GMO Cultivation under the Deliberate Release Directive and the Comitology Reform Post-Lisbon
© Lexxion Verlagsgesellschaft mbH (12/2010)
“After a reform is before another reform.” This paraphrasing of a famous saying from the world of football seems to be a very fitting way to describe the status quo of the European policy on genetically modified organisms (GMOs). The functioning of the EU legal framework on GMOs has since its initial establishment in the 1990s been troubled by political disagreement, deadlocks in decision-making, strong public opposition in the Member States, and considerable delays in the process of authorisation of genetically engineered products on the internal market of the EU.

The New Strategy on Coexistence in the 2010 European Commission Recommendation
© Lexxion Verlagsgesellschaft mbH (12/2010)
The European Union tried to establish a “coexistence” policy for the cultivation and processing of GM and non-GM products after the political agreement that put an end to the 1999-2004 moratorium. Consequently, coexistence is part of this gentlemen’s agreement between States with pro and anti-GMO positions.

EU GM Crop Regulation: A Road to Resolution or a Regulatory Roundabout?
© Lexxion Verlagsgesellschaft mbH (12/2010)
Since first embarking on the road of risk management options for the regulation of recombinant DNA (rDNA) activities and use in 1978, the European Union (EU) has largely failed to create a regulatory and policy environment regarding genetically modified (GM) crops and their cultivation that is (a) efficient, (b) predicable, (c) accountable, (d) durable or (e) interjurisdictionally aligned.

Wertstoffhof 2020 - Neuorientierung von Wertstoffhöfen
© ia GmbH - Wissensmanagement und Ingenieurleistungen (4/2015)
Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?

Versuch einer neuen Definition kommunaler Daseinsvorsorge
© ia GmbH - Wissensmanagement und Ingenieurleistungen (7/2014)
Wir leben in einer Zeit immer komplexerer, unübersichtlicher werdender Lebensumstände. Sie fordern dazu heraus, wichtige Grundprinzipien neu zu überdenken oder gar neu zu definieren. Aber ist das wirklich hilfreich oder gar notwendig? Genügt es nicht, auf die Wurzeln solcher Grundprinzipien zurückzugehen und daraus eine Orientierung für die moderne Welt von heute abzuleiten?
