Loligo sponsors Nothobrancius Symposium
The Nothobranchius Symposium is a biennial meeting that serves as a platform for researchers with an interest in all aspects of Nothobranchius biology from biomedical to ecological research to meet and discuss ideas.
We will be sponsoring the 4th Nothobranchius Symposium in Brno, Czech Republic, on 3-5 June 2020, in order to support this interesting scientific community.

Loligo sponsors SEB symposium
Once again, we have agreed to sponsor a symposium. This time for the SEB Annual Meeting in Prague 2020. The symposium is organized by Prof. Patricia A. Wright (Univ. Guelph) and Dr. Jonathan M. Wilson (Wilfrid Laurier Univ.), and we will provide travel funds to three post docs and invited speakers: M. Mandic, S. Fehsenfeld, and M. Giacomin.
Please find a description of the symposium below:
Title: The Ins and Outs of the Ups and Downs: Respiration and Osmoregulation in Fluctuating Environments
Aquatic ectotherms are intimately linked to their environment. Daily and seasonal variation in water conditions (e.g., salinity, oxygen, carbon dioxide) often have dramatic impacts on behaviour and physiology of freshwater and marine organisms. Two critical systems, respiration and osmoregulation are linked through gill morphology and transport processes. The "osmo-respiratory compromise" describes the complex interactions between the two systems. Speakers will explore respiratory and/or osmoregulatory challenges and behaviour in invertebrates and vertebrates facing fluctuating conditions in a wide range of habitats, such as tide pools, coral reefs, mangrove forests and freshwater lakes.

P50 data on hybrid hemoglobin from high-altitude vertebrates interbreeding
Dr. Jay Storz and Anthony Signore from University of Nebraska used our BOBS™ instrumentation to measure O2 affinity (P50) of hemoglobin from Tibetan wolves and mastiffs.
This new impressive research on Tibetan mastiffs gaining high-altitude adaptation by breeding with mountain wolves is highlighted on Live Science (https://www.livescience.com/tibetan-mastiff-wolf-genes.html).

MO2 near Ucrit in rainbow trout
Yangfan Zhang and his collaborators from University of British Columbia, Canada, used a 10 L Loligo® swim tunnel to assess the dynamic nature of ṀO2active near Ucrit in rainbow trout (Oncorhynchus mykiss). The researchers used various sampling windows and introduced an iterative algorithm which generated a 23 % higher peak ṀO2active compared to conventional ṀO2 sampling rates and interval regression analysis of ṀO2active.
In the current version of AutoResp, calculating ṀO2active near Ucrit is also possible by enabling the mode “Closed respirometry” during this critical phase. This mode enables you to get MO2 values on-the-fly for any time interval you prefer!

Stickleback thermal preferences
Post doc Natalie Pilakouta from University of Glasgow, and her collaborators (Holar College), used the shuttle box system and ShuttleSoft to look at thermal preferences in three-spined stickleback (Gasterosteus aculeatus). The researchers find that fish from both warm (from freshwater warmed by geothermal activity) and cold (from ambient-temperature lakes) habitats had an average preferred temperature of 13 °C, which is considerably lower than the temperatures experienced by fish in warm habitats for most of the year. The results therefore claim to challenge the assumption that temperature preferences in ectotherms will readily evolve as a response to climate change.
Temperature preference does not evolve in sticklebacks despite multigenerational exposure to elevated temperatures

Oxygen consumption in Daphnia magna
Prof. Mikko Nikinmaa from University of Turku, Finland, and his collaborators, used the microplate respirometer to analyze whether exposure to water-soluble fraction (WSF) of crude oil can be associated with changes in interindividual variability in phenotype in Daphnia magna. The 80 µl well microplate allowed the researchers to measure whole animal oxygen consumption rate and found that the variability of oxygen consumption rate decreased in 48 h 30 % WSF-exposed animals as compared to 10 % WSF-exposed or control animals. Furthermore, they observed that the oxygen consumption rates in F1 and F2 generations of unexposed and 10 % WSF-exposed Daphnia had decreased from parental F0 generation and were also lower than in offspring of 30 % WSF-exposed specimens.
Water-soluble fraction of crude oil affects variability and has transgenerational effects in Daphnia magna
