(Press-News.org) Nocturnal basking has only recently been reported in wild freshwater turtles, but this study suggests that the behaviour is widespread and occurs in many species.
Postdoctoral Researcher at La Trobe University Dr Donald McKnight said he first observed freshwater turtles nocturnal basking at the Ross River in Townsville.
“They were coming up at night and sitting on logs exhibiting very much the same behavior they do during the day; when we looked into it, it wasn’t something that turtles reportedly did,” Dr McKnight said.
“We think it's related to temperature. The water is staying so warm at night that it's actually warmer than the turtles like to be and they can cool down by coming out of the water.”
“It’s widespread across the turtle family tree, with the caveat that it is only in the tropics and the subtropics where it occurs,” Dr McKnight said.
Dr McKnight first observed the behaviour with a colleague, Dr Eric Nordberg at the University of New England, on the banks of the Ross River in Townsville, Australia.
For this study a team of researchers from around the world put cameras on basking logs to monitor the nocturnal activity of as many freshwater turtle species as possible.
Cameras taking one photo every two minutes were set up in 25 locations across Australia, Belize, Germany, India, Seychelles, Senegal, Trinidad and Tobago, the USA and South Africa. These captured data on 29 species from seven of the freshwater turtle families.
The study Nocturnal basking in freshwater turtles: a global assessment, was published in Global Ecology and Conservation.

Simultaneous diagnosis and treatment of cancer now possible
2023-04-04
Cancer is not incurable anymore. Nevertheless, according to statistics released by Statistics Korea last year, cancer remained the primary cause of mortality in Korea in 2021. This highlights the ongoing struggle against cancer, which demands effective prevention measures as well as timely diagnosis and prompt intervention through effective treatment. However, the question remains whether it is feasible to provide treatment promptly upon diagnosis.

Study to decode microbe-gut signaling suggests potential new treatment for IBD
2023-04-04
Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis.
The potential treatment pathway emerges from a study led by experts at Cincinnati Children’s published online March 28, 2023, in the Journal of Experimental Medicine. Co-first authors were Garrett Overcast, PhD, and Hannah Meibers, BS. Corresponding author was Chandrashekhar Pasare, DVM, PhD, Division of Immunobiology and ...
Efficient nanostructuring of glass with elliptically polarized pulses
2023-04-04
The photoexcitation, and especially photoionization, is one of the most important manifestations of the light-matter interaction in nature, ranging from photosynthesis in plants and vision in biology to photography and laser processing of materials. It is generally accepted that the change in a substance is weaker, the less light is absorbed. Here we found that this is not always the case.
In a new paper published in Light Science & Application, a team of scientists, led by Professor Peter G. Kazansky from Optoelectronics Research Centre, University of Southampton, United Kingdom and co-workers have demonstrated efficient ultrafast laser nanostructuring ...
Warming Arctic draws marine predators northwards
2023-04-04
Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
The seas surrounding the Arctic are important fisheries and ecological regions; they are also among the areas most affected by climate change. The effects of warming waters and loss of sea ice on the biodiversity of these waters, and hence their ecology, is still not fully understood.
An international team of researchers led by Dr. Irene D. Alabia at the Arctic Research Center at Hokkaido University has examined Arctic-wide ...
New low-cost camera could help scientists forecast volcano eruptions affecting millions
2023-04-04
Gas emissions are the manifestation of activity occurring beneath the surface of a volcano. Measuring them lets researchers see what can’t be seen from the surface. This knowledge is vital for hazard monitoring and the prediction of future eruptions. Since the mid-2000s, ultraviolet SO2 cameras have become important tools to measure emissions. The measurement campaigns, however, must be accompanied by a user, making SO2 cameras unsuitable for acquiring long-term datasets. Building and operating this type of camera can cost upwards ...
Personal finances increasingly play second fiddle to personality, finds lonely hearts ad study
2023-04-04
Personality has become a more important factor than finances when it comes to dating, a new study has found.
Researchers from the University of York and the University of Essex analysed more than a million lonely hearts ads and found that in the USA, France, and Canada, there was a sharp decline in economic factors when choosing a partner. However, finances remained an important issue in India when it came to relationships.
To see how partner preferences changed over time, the researchers analysed lonely hearts ads from various major news outlets from Canada, France, and India. They collected data from publications from 1950 to 1995, the year that most of these ads shifted to being online. ...
Double-anonymous peer review reduces reviewer bias, finds three-year trial
2023-04-04
Today (4 April) the British Ecological Society has published the results of a three-year randomised trial comparing double and single-anonymous peer review in the journal Functional Ecology. The findings indicate a reduction in reviewer bias when author identities are anonymised.
The three-year randomised trial in the journal Functional Ecology, provides the most compressive data yet on the effects of anonymising authors during scholarly journal peer review.
Double-anonymous peer review, also referred to as double-blind peer review, is where author identities are not disclosed to reviewers. This differs from single-anonymous peer review where reviewers know ...
Study finds harmful PFAs don’t actually prevent furniture stains
2023-04-04
The health and environmental harms of per- and polyfluoroalkyl substances (PFAS) are well-known, but a new peer-reviewed study calls into question their touted stain-fighting benefits. The study, published today in the AATCC Journal of Research, tested the performance of PFAS finishings on furniture fabrics and found that they had limited to no effectiveness, particularly under real-world conditions.
“It was surprising that these harmful but supposedly indispensable chemicals had no practical benefit,” said lead author Jonas LaPier, a PhD ...
Scientists call for coordinated global effort to assess the full environmental impacts of tritium
2023-04-04
Scientists have called for a coordinated international effort to fully assess the environmental impacts of tritium ahead of a significant expected rise in its global production.
A radioactive isotope of hydrogen, tritium is a by-product of the nuclear industry and its presence is predicted to grow exponentially with nuclear increasingly seen as being key to the global low carbon economy.
That will result in many nations having to develop long-term strategies to manage tritiated radioactive waste and develop tools to both assess and address its environmental impact.
However, writing in the journal Science of the Total Environment, ...
Study highlighting female-led migration into Bronze Age Orkney wins Current Archaeology’s prestigious Research Project of the Year award for 2023
2023-04-03
A revolutionary investigation that shed vivid light on pioneering female migrants who made their way to Orkney during the Bronze Age has won Research Project of the Year at the prestigious Current Archaeology Awards for 2023.
The project – a collaboration between EASE Archaeology and the University of Huddersfield – focused on human remains excavated at the Links of Noltland, a Bronze Age cemetery on the island of Westray. This work revealed the first concrete evidence of a major influx of non-local people into Orkney during the Bronze Age – and, significantly, it appears that this migration ...
