🐟 Four behavioural states of seabass defined based on level of heart rate and acceleration 💓

In a recent study, a team from  @IMEDEA_UIB_CSIC & @WUR implanted 12 European seabass with @staroddi DST milli-HRT ACT biologgers and subjected them to swim tunnel and crowding test. They measured a range of parameters including cost of transport (COT), head width frequency (HWF), head width amplitude (HWA), tail beat frequency (TBF), oxygen consumption (MO2), heart rate (HR), acceleration (ACC) and QRS wave amplitude (AMP).

🐀 Heat Therapy Influences Thermoregulation and Behaviour in HFpEF Rats

🌟 In a recent study, researchers from @LifeAtPurdue @ufscaroficial @AuroraU and @ERAUWorldwide investigated whether heat therapy, a promising cardiovascular intervention, can restore functional sympatholysis in HFpEF rats.

🌟 A total of 20 rats were implanted with @staroddi's DST micro-ACT, small activity and temperature loggers. The physio-loggers were set to measure core body temperature every 3-4 minutes and activity every 7 minutes over 8 weeks.

📢Laboratory & Wildlife Newsletter December edition is out! Perfect reading during the holidays!

🐭 Containing an article on how Basal Metabolic Rate (BMR) shapes thermoregulation in cold-stressed mice where Star-Oddi's tiny nano-sized temperature loggers were used measuring body temperature.
🐀It also covers a study where our small DST micro-ACT activity loggers were used when investigating how heat therapy influences thermoregulation and behaviour in HFpEF rats.

🐟🌊Warming seas push polar cod out of Iceland’s waters
A new long-term study from @MFRI_Iceland reveals that polar cod is steadily retreating from the waters around Iceland as ocean temperatures rise. The research draws on nearly 40 years of standardised trawl surveys and shows a clear pattern: as waters warm, polar cod retreat northward and into deeper, colder environments.
Bottom temperatures during trawls were recorded using StarOddi's Starmon TD temperature and depth loggers, which were attached directly to the trawl gear and recorded temperature every minute. Their data were used to validate and correct readings from the main sondes, providing a consistent, high-resolution temperature record over multiple decades.

🌟 Why study emerging H5N1 strains in ferrets? 💉

The rapid evolution and global spread of highly pathogenic avian influenza (HPAI) H5N1 viruses, particularly subclade 2.3.4.4b, have raised serious concerns about their potential to cause future pandemics. To better understand the risks posed by newly circulating strains and to support the development of effective countermeasures, researchers are using updated ferret models to study the pathogenesis and virulence of these viruses under controlled conditions.

Scientists from Cerba Research, The Netherlands, Stiftung Tierärztliche Hochschule Hannover/University of Veterinary Medicine Hannover, Germany, and Star-Oddi, Iceland, implanted subcutaneously Star-Oddi DST micro-ACT loggers in 9 ferrets. The loggers were set to measure temperature every 5 minutes, and additionally they recorded raw tri-axial acceleration at 10Hz for one minute in the time space of 4 a.m.-5 a.m. and 4 p.m.-5 p.m. from which respiration rate was calculated.

🔥 New in Nature: Streamlining an A(H5) Influenza Vaccine 💉

🔥Hot off the press in Nature (@SpringerNature), a group of scientist from @erasmusuni, @UniUtrecht & @Cambridge_Uni have mapped the global antigenic evolution of avian influenza A(H5) by constructing a high-resolution antigenic map of 127 HA antigens. They implanted 6 ferrets in each group with #staroddi DST micro-T #tinytemperatureloggers 14 days after the prime vaccination.👇

📢 The December edition of our Ocean & Fish Research Newsletter is out!
It includes a long-term study (40 years!) which reveals that polar cod is steadily retreating from the waters around Iceland as ocean temperatures rise. Our robust Starmon TD loggers were used attached on trawls for temperature measurements.

Furthermore, it includes a recent study where our DST milli-HRT ACT heart rate and activity logger was used in European seabass.

🐟 High-density farming raises stress in olive flounder

In recent study published in Aquaculture Elsevier @AquaticSciences, researchers from Chonnam National University and the National Institute of Fisheries Science in South Korea aimed to move beyond traditional stress indicators such as cortisol. They equipped 16 olive flounders with Star-Oddi's implantable biologgers DST milli-HRT.

🦀 Tiny crab tenants reveal the coral reef’s hidden strength

In a two-year study, scientists from @KAUST, @univgroningen, and the Naturalis Biodiversity Center have uncovered surprising secrets about one of the reef’s smallest residents — coral-dwelling gall crabs. Despite being only a few millimetres long, these crabs play a crucial but often overlooked role in the health and resilience of coral ecosystems.

The research team tracked 799 individual crabs living on 517 coral colonies across four reefs in the central Red Sea. In 2023, a severe coral bleaching event struck the region. To understand the environmental trigger, the team deployed Star-Oddi 🌟 DST CT conductivity and temperature loggers 🌟 , which recorded water temperature every ten minutes. The loggers provided a crucial link between rising ocean temperatures and the coral community’s collapse offering data on how heatwaves develop in the ocean.
