Water Costs of Gas Exchange by a Speckled Cockroach and a Darkling Beetle.

Waseem Abbas, Philip C. Withers and Theodore A. Evans

Insects and plants face a similar challenge – how to exchange metabolically important gases with the environment while limiting water loss?

The team at the School of Biological Sciences at the University of Western Australia measured the ratio of water loss to metabolic rate in insects using Qubit’s S151 CO2 analyzer for metabolic rate measurements.

We are especially pleased that Dr. P.C. Withers, author of numerous seminal works on gas exchange techniques placed his confidence in Qubit equipment.

The S151 CO2 Analyzer

Metabolic performance and thermal and salinity tolerance of the coral Platygyra carnosa in Hong Kong waters.

Walter Dellisantia, Ryan H.L. Tsang, Put Ang Jr, Jiajun Wu, Mark L. Wells, Leo L. Chan

In this collaboration between the University of Hong Kong and the University of Maine, Dellisantia et al. use the unique CISME system to monitor respiration, photosynthesis and calcification in corals, in situ and non-invasively.

Results provide insights into the effect of climate drivers on P. carnosa metabolism allowing predictions concerning coral health under future climate change scenarios.

Vegetative desiccation tolerance in Eragrostiella brachyphylla: biochemical and physiological responses.

Neeragunda Shivaraj Yathisha, Plancot Barbara, Bruno Gügi, Kambalagere Yogendra, Sudisha Jogaiah, Driouich Azeddine, Ramasandra Govind Sharatchandra

Q-Box-CO650 Plant CO2 Analysis Open for Viewing

A joint Indian-French collaboration in which the CO650 was used to measure photosynthesis and transpiration in a desiccation-tolerant plant able to survive in the air-dry state and recover completely on availability of water. Biochemical and physiological mechanisms for this remarkable ability are discussed.

Seasonality and moisture regime control soil respiration, enzyme activities, and soil microbial biomass carbon in a semi-arid forest of Delhi, India.

Urvashi Tomar and Ratul Baishya

The SR1LP was used in India for seasonal field measurements of soil respiration over a year.

Soil moisture and temperature played a significant role in determining variations in soil microbiological processes in a landscaope sensitive to environmental changes. The role of various enzyme activities was also assessed.

Sex-related interannual plasticity in wing morphological design in Heliconius charithonia enhances flight metabolic performance.

V.I. Ramos-Pérez, I.Castellanos, V.A.Robinson-Fuentes, R. Macías-Ordóñez, L.Mendoza-Cuenca

In this Mexican study, resting metabolic rate and post-flight metabolic rate in butterflies were measured by open-flow gas exchange using the RP1LP, comprising O2, CO2, mass flow and temperature analyzers.

Measurements were made over two years on males and females with variations in wing morphology related to optimum flight design.

Impact of salinity changes on growth, oxygen consumption and expression pattern of selected candidate genes in the orange mud crab (Scylla olivacea).

Md. Lifat Rahi, Tanzina Ferdusy, Shams Wali Ahmed, Nuruzzaman Khan, Dania Aziz, Krishna, R. Salin

Researchers based in Bangladesh, Malaysia and Thailand used the QBox Aqua to monitor metabolic rate via changes in DO2 at different salinities.

Changes in growth and mRNA expression were also measured. Results indicated that with proper acclimation, Scylla olivacea can be farmed at low salinity conditions and possibly in freshwater conditions.

Do personalities co-vary with metabolic expenditure and glucocorticoid stress response in adult lizards?

H. Mell, R. Josserand, B. Decencière, P. Artacho, S. Meylan & Jean-François Le Galliard

This paper from French and Chilean researchers is not from 2020, but it has our favorite title.

The authors used our unique differential O2 analyzer with a 1 ppm O2 resolution against air to study standard metabolic rate correlations with activity, aggression, risk taking and sociability in lizards.

Exceptionally cool stuff.

Feature your Research in our Blogs and Newsletters

Do you have exciting research to share? Tell us about it and the Qubit equipment you use! We’d be pleased to feature your successes with our scientific community in an upcoming blog or newsletter.


Qubit | Affordable Quality and Service

We are research biologists who understand the requirements and budgetary constraints of fellow scientists. We offer the highest possible quality at the lowest possible price, without compromising accuracy, resolution or durability. Many of our analyzers are still in active use after more than 20 years. Our clients agree:

“When purchasing a new gas exchange system for research purposes, I took a chance with Qubit systems. I now have a reliable and versatile system that is just as accurate as the more expensive competition. Most importantly, I received outstanding service during all phases of purchase: conception, ordering, installation and continuing help.”

Dr. Bill Shipley, Département de Biologie, Université de Sherbrooke, Quebec, Canada

“I have used one of your CO2 monitoring systems for atmospheric CO2 measurements,successfully and continuously since 2010 and would like to thank you for manufacturing such a reliable instrument.”

Dr. A. Cemal Saydam, Hacettepe University, Turkey
