Why upgrade to LoliTrack 5?

The latest version of LoliTrack is out! This major upgraded version features many improvements and additions as well as a much faster performance on regular PCs.

IMPORTANT: We offer a 50 % discount to all LoliTrack 1-4 and DanioTrack license holders. This offer is valid in 2020 only. For more information, click here.

LoliTrack 5 includes several tracking tools that will save a lot of time. An example is tracking organisms in 24-, 48-, and 96-well microtiter plates for fast screening of activity levels or locomotion:

Another example is that LoliTrack 5 can identify specific body points (tail, head, midline center, center of gravity) as well as the object midline which is especially useful for studying kinematics (tail beat frequency, body oscillations etc.) or specific behavior (direction of orientation or movement, turning rate etc.). A new parameter, “BEND”, can be calculated as well giving body angles, i.e., for automated tracking of tailbeat frequency or other body oscillations:

Nearest Neighbor Distance / Inter-Individual Distance
You can export a visual representation as well as the position data for nearest neighbor distance and inter-individual distance for multiple objects:

Heat mapping is now an option as well for specific parameters like position, speed, acceleration etc.:

Other important updates include the possibility to correct tracking errors like object identity switching or even if the object leaves and re-enters the arena.

LoliTrack 5 supports 3D tracking and analysis. With two cameras (or video files), users can track and analysis the behavior of a single object in 3D. The 3D tracking feature further allows exporting the trajectories as a 3D model or as video for data presentation:

LoliTrack 5 has been optimized with performance in mind. On regular Windows 10 PCs, users of LoliTrack 5 will find that calibrating, creating filters and indeed tracking runs more smoothly and faster compared to the previous version, LoliTrack 4. The follow diagram shows six examples of how many seconds it took to track the same video in LoliTrack 5 compared to LoliTrack 4:

LoliTrack 5 now supports most video file formats unlike previous version that only handled .AVI files.

Another new feature in LoliTrack 5 is the built-in video recorder. The video recorder allows the user to capture and edit videos from within LoliTrack 5 using most cameras connected to the PC.

The entire LoliTrack 5 interface has been redesigned to meet today’s clean and streamlined user demands. Tracking a video follows an intuitive step-by-step procedure: Load video file > Calibration > Masking > Filtering > Tracking > Analysis. Several time-saving features have been added; including the option to track a user-defined interval of the entire video or to quickly define the filter by subtracting the background.

Sponsoring NoWPaS 2020 meeting

We are happy to be sponsoring the NoWPaS 2020 meeting at Laugarvatn, Iceland, on March 2nd – 7th. NoWPas focuses on all anadromous salmonid species and will be celebrating its 15th anniversary this year.

NoWPaS has succeeded in organizing annual workshops since its inception in Norway in 2005. Over the next fourteen years, a total of 380 early-stage researchers and 59 invited speakers have had the opportunity to give oral presentations regarding their research on salmonids.

The workshop is free for all delegates and is first come, first serve among eligible applicants.

We hope for a great meeting in Iceland!

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.

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 ṀOsampling 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
