Forscher der Hochschule Kaiserslautern in ZDF-Dokumentation Am Samstag, den 12. Oktober, um 20:15 Uhr auf ZDF Info startet die spannende fünfteilige Doku „Katastrophen der Erdgeschichte“, die von der Entstehung der Erde bis zu den Menschen reicht. In den ersten beiden Folgen sind die Forscher Patrick Jung und Michael Lakatos von der Hochschule Kaiserslautern zu sehen, die sich mit Mikroorganismen beschäftigen, die die Welt verändert haben, wie zum Beispiel Cyanobakterien. Diese Organismen haben vor etwa 3,5 Milliarden Jahren die oxygene Fotosynthese entwickelt. Sie nutzten Wasser (H2O) als Elektronenspender und setzten Sauerstoff frei – ein hoch reaktionsfreudiges Gas, das zur Entwicklung der Sauerstoffatmosphäre führte und das Aussterben vieler sauerstoffempfindlicher Organismen zur Folge hatte. Seid dabei und seht diese und weitere spannende Katastrophen der Erdgeschichte. Faszinierenden Bildern aus der ganzen Welt u.a. mit den Kaiserslauterer Forschern und unserer WALZ IMAGING-PAM!

The LEAF-STATE-ANALYZER LSA-2050 is a handheld device for non-invasive leaf analysis and gives a picture of how leaves and plants cope with their light environment (both UV and visible light). Join our session with Dr. Gert Schansker on the following dates: Tuesday, October 08 at 5:00 pm (CET) or Thursday, October 10 at 9:00 am (CET)

This Week photos from 23th & 24th September 2024 Labquip was having WALZ Training with our teams and users participant to know more details for Walz photosyntesis equipment. This events was held at The Lab (Hall Event) CO-LABS Coworking at Sekitar 26 Enterprise Shah Alam. Thank you all the users from many universities and also our Labquip teams from Labquip (Thailand) Ltd. , Labquip Singapore & Labquip Labquip Indoprima to also for our Speaker Dr.Gert Schansker , Scientist application from HEINZ WALZ GMBH for spent some times and together we success this event. #Walz #training #labquipasia #labquipmalaysia

WALZ's MICRO-PAM - Understanding Tropical Forest Resilience at Biosphere 2 We're excited to share ongoing work using the three-sensor MICRO-PAM we loaned to the University of Arizona’s Biosphere 2 earlier this year. Biosphere 2 is a unique research facility containing several ecosystems, including a 34-year-old tropical rainforest housed within a 26,700 m³ space, where the canopy trees have grown all the way to the glass ceiling. In this controlled environment, leaf temperatures can soar above 50°C (122°F) right under the glass—the temperature seasonality and temperature gradient create a perfect setting for investigating how increased temperatures impact the photosynthetic apparatus of leaves, known to be the most temperature-sensitive component. In this study, Assistant Research Professor Joost van Haren, NSF-funded undergrad student Andrew Hernandez, and researcher Jason de Leeuw used our MICRO-PAM to measure the fluorescence response of mature, sun-exposed leaves across six tree species from the understory (including coffee and cacao) to the top of the rainforest canopy during the peak of summer. The highest leaf temperature recorded with a MICRO-PAM sensor was 50.3°C. While the team continues to analyze their data, initial analysis suggests: - Leaves exposed to higher temperatures from the same species can maintain photosystem II activity at temperatures more than 5°C higher. - Electron Transport Rate (ETR) is primarily affected by intense light conditions, though there's a marked drop in ETR at temperatures exceeding 45°C. - Interestingly, only the leaf that reached the highest temperature showed a significant decrease in dark-adapted Fv/Fm, which fully recovered within a few days. These early results hint at the resilience of tropical tree species, suggesting their ability to recover from short-term heat stress—a crucial finding given the concerns that tropical forests may be nearing their temperature limits due to climate change. We are proud to aid the Biosphere 2 team in their studies of our tropical forests in the face of climate change! #ClimateChange #PhotosynthesisResearch #TropicalForests #MICROPAM #Biosphere2 #EnvironmentalScience #Resilience #HeatStress #ETR #FvFm Heinz Walz GmbH University of Arizona

Mit Walz Messgeräten widerstandsfähige Korallen finden und Riffe retten. Prof. Dr. Christian Voolstra (Professor für Genetik der Anpassung in aquatischen Systemen an der Universität Konstanz) erklärt im Science Talk des SWR, dass die globale Erwärmung der Meere dramatische Auswirkungen auf die Gesundheit der Korallenriffe hat. Diese werden wegen ihrer Artenvielfalt nicht umsonst als „Regenwald“ der Meere bezeichnet. Die WALZ Produkte JUNIOR-PAM und IMAGING-PAM werden in Konstanz zur Messung der Korallengesundheit eingesetzt, um Arten zu finden die auch unter geänderten Bedingungen in der Lage sind, den Kollaps dieses wichtigen Ökosystems zu verhindern.
