UGT meets people at Expo 2020 in Dubai

The managing director and partner of UGT – Dr. Sascha Reth – used the time between Christmas and New Year to discuss the possibilities of the Ecotrons and Lysimeters of UGT GmbH with interested scientists from the Arabian Peninsula.

A special highlight was our EcoUnit, which will be exhibited in the German Pavilion of the Expo 2020 in Dubai until April 2nd 2022 in the Biodiversity Lab.

The discussions were also used to organize follow-up meetings and on-site training. Already in March, the UGT will be back at the Expo 2020. Take the opportunity to make an appointment with us at the Expo 2020.

Win with Umwelt-Geräte-Technik: A trip to Dubai and celebrate with us at the “Expo 2020 Dubai”!

Our EcoUnit has been selected!

We are at the “Expo 2020 Dubai” – it`s a very special occasion that we would like to celebrate together!

With the EcoUnit – we are represented in the German Pavilion and proud of it. It is a special honor for us and our work to be involved in this forward-looking mega-event.

The international exhibition is expected to have 25 milion visitors from all over the world and is titled “Connecting Minds, Creating The Future”. It is a unique place where global knowledge and the latest developments in research are bundled together. The focus is on climate protection, sustainability, renewable energies and mobility.

Our EcoUnit is located in the “Sustainability District” in CAMPUS GERMANY. A perfect location for the pioneering measurement system. It simulates climate scenarios and allows effects on ecosystem functions in the soil-plant-atmosphere continuum to be demonstrated. The EcoUnit is already an important building block for experiments, because it creates the basis for solution strategies for a sustainable future!

UGT visits their partner In-Situ in the US

Stefan Rösel and Dr. Sascha Reth took the opportunity to visit In-Situ in Fort Collins, Colorado. After end of  the travel ban, it was good to meet each other in reality and get updated for new product developments.

UGT is the German representative of In-Situ products. The sensors and solution fits perfect to the product portfolio of UGT.

Good news from the development department of In-Situ. Live Readings Graphing for VuSitu are available!  This enables all the things people use graphs for – easy tracking of stabilization, visualization of changes over time, and many more! 

UGT in South Korea

After the long time of travel restrictions, we are starting the maintenance work, now. Our team worked successfully for the last 2 weeks at the world largest lysimeter station with 92 lysimeters altogether.

In-Situ Release von 3 neuen Sensoren!

Gute Nachrichten kommen von unserem Partner In-Situ zum nahenden Jahresende für all unsere KundInnen aus Wassersektor und -forschung:

Für unsere In-Situ Multiparameter-Sonden AquaTroll 500/600 gibt es jetzt 3 neue Sensoren:

  • Aqua Troll Fluorescein WT Sensor (Uranin)
  • Aqua Troll Crude Oil Sensor
  • Aqua Troll FDOM Sensor (Fluoreszierendes gelöstes organisches Material)

Der Release, auf den viele Kunden lange gewartet haben und der das Anwendungsspektrum der Sonden merklich erweitert:

Fluorescein/Uranin ist ein wichtiger Tracer in der Hydrogeologie, auf Deponien und zur Detektion von Leckagen.

Fluoreszierendes gelöstes organisches Material (FDOM) dient als zusätzlicher Indikator um Mischprozesse zu verstehen oder Komponenten und Anteile von Einträgen organischer Materie zu untersuchen, z.B. in Küstengewässern. Auch die Wichtigkeit der Überwachung von gelöstem Rohöl in Küstengewässern oder Bundeswasserstraßen steht außer Frage.

Alle 3 Sensoren nutzen die einzigartige optische Sensor-Technologie der In-Situ Fluorometer: mit integriertem Referenzdetektor der die Lichtintensität misst und Änderungen bei jeder Messung kompensiert, und mit besonders engen Frequenzbereichen zur Vermeidung der Interferenz mit anderen Fluoresenzquellen. Durch die In-Situ eigene Smart-Sensor Strategie können Sie die neuen Sensoren problemlos mit den bestehenden kombinieren und an jedem beliebigen Steckplatz installieren – die individuelle Werkskalibrierung ist auf dem Sensorkopf gespeichert.

Für jeden der neuen optischen Sensoren hat In-Situ außerdem eine innovative Festkörperreferenz für die Kalibrierung herausgebracht – für eine schnellere und einfachere Kalibrierung.  Sie können auch auf “traditionelle Weise” mit Standardlösungen kalibriert werden, aber mit den Festkörperreferenzen wird die Kalibrierung einfacher und schneller.

Nutzen Sie die Gelegenheit für ein Upgrade Ihres AquaTrolls noch vor Jahresende, oder planen Sie die Anschaffung Ihres Aqua Trolls für die nächste Saison schon fest mit ein!

New Publication: “The iDiv Ecotron – a flexible research platform for multitrophic biodiversity research”

First published: 04 October 2021


Across the globe, ecological communities are confronted with multiple global environmental change drivers, and they are responding in complex ways ranging from behavioral, physiological, and morphological changes within populations to changes in community composition and food web structure with consequences for ecosystem functioning. A better understanding of global change-induced alterations of multitrophic biodiversity and the ecosystem-level responses in terrestrial ecosystems requires holistic and integrative experimental approaches to manipulate and study complex communities and processes above and below the ground. We argue that mesocosm experiments fill a critical gap in this context, especially when based on ecological theory and coupled with microcosm experiments, field experiments, and observational studies of macroecological patterns. We describe the design and specifications of a novel terrestrial mesocosm facility, the iDiv Ecotron. It was developed to allow the setup and maintenance of complex communities and the manipulation of several abiotic factors in a near-natural way, while simultaneously measuring multiple ecosystem functions. To demonstrate the capabilities of the facility, we provide a case study. This study shows that changes in aboveground multitrophic interactions caused by decreased predator densities can have cascading effects on the composition of belowground communities. The iDiv Ecotrons technical features, which allow for the assembly of an endless spectrum of ecosystem components, create the opportunity for collaboration among researchers with an equally broad spectrum of expertise. In the last part, we outline some of such components that will be implemented in future ecological experiments to be realized in the iDiv Ecotron.
