Aquatic Biology Research

+

World Water Day was March 22nd.  Learn here what water means to different people. In this newsletter, we highlight recent publications from aquatic biologists using Qubit equipment. For all aspects of animal and plant metabolism, including aquatic research, we are committed to providing instrumentation of exceptional quality at the most affordable prices.

Temperature induced changes in physiological traits and expression of selected candidate genes in black tiger shrimp (Penaeus monodon) larvae.

Temperature is an important abiotic factor that influences growth, development and metabolic performance, as well as sex determination, of aquatic organisms.  This study with black tiger shrimp larvae used the Q-BOX AQUA to examine 6 temperature treatments between 24 and 34C, and found that higher temperature significantly increased the growth and metabolic performance of shrimp as well as resulted in greater proportion of females.

crab

This study, conducted using the Q-BOX AQUA, evaluated the physiological and behavioral performance of the Colombian freshwater crab over a temperature range from 8 to 30C. It was shown that metabolic rate increased significantly up to 26C and then stabilized, while the activity of the crab increased up to 26C and then significantly decreased at higher temperatures, indicating behavioral compensation for increased thermal stress.

CISME

gal substrates on dead and live coral were studied in situ using the CISME underwater system for monitoring respiration, photosynthesis and calcification.  Daytime rates of calcification were the same on both live and dead corals. In the dark, calcification of the live coral continued at lower rates, whereas carbonate dissolution occurred on dead corals.  Rates of algal photosynthesis on dead coral communities was up to 5 times higher than on live communities. Implications for the health of coral reefs are discussed.

Qubit | Well Designed Systems | Easily Serviced | Outstanding Technicians

“We have been using the Q-Box AQUA respirometry package for a year and have been impressed with the quality and versatility of the system. The mechanical systems are well designed and easily serviced and the software is intuitive and flexible enough for use in diverse applications. The technicians at Qubit are outstanding; they were able to modify the system to suit our particular needs and they have always been quick to respond when technical support was required. The fact that Qubit ships the system in a protective case was also a big plus for field work!”

Dr. Tyson MacCormack, Biology Department, Mount Alison University, New Brunswick, Canada
