Fish study shows infection alters sleep
A team led by NC³ members has investigated whether and how the immune system can influence the behaviour of sticklebacks.
It’s a well-known fact that if you don’t get enough sleep, you’re more likely to get sick. And it has also been observed that people sleep differently when they’re infected. Biologists from the Institute for Evolution and Biodiversity at the University of Münster have now investigated how a parasite infection affects the immune system and sleep in three-spined sticklebacks infected with their natural parasite, the tapeworm. One conclusion was that infected fish sleep longer after infection than their uninfected counterparts. However, the team only observed this difference one month after infection. In the first few days, there were virtually no differences. The results should help to deepen our understanding of the interactions between macroparasite infections, sleep and the immune response.

Plant chemicals shape animal social lives
A study published in the Journal of Animal Ecology by researchers from Bielefeld University reveals that certain plant compounds, from non-food plants that then affect the social behavior and lifespan of the turnip sawfly (Athalia rosae). Led by Dr. Pragya Singh, a NC³ postdoctoral researcher from the Chemical Ecology group in Bielefeld, the team investigated how the consumption of specific non-nutritional plant-derived chemicals, known as clerodanoids, alters social networks within sawfly populations while simultaneously shortening the insects’ lifespan. These findings provide valuable insights into plant-animal interactions and social networks in ecology.

Social interactions may accelerate evolution
How do animal species develop evolutionarily? Researchers usually predict this by studying a species' genes and the environment in which it lives. However, new research highlights a key factor that is often overlooked: social interactions, in which the genes of other individuals play an important role in shaping the environment an animal experiences. NC³ members Maria Moiron and Alfredo Sánchez-Tójar and researchers from the British Universities of Aberdeen and Exeter collaborated on the study, which was published in Evolution Letters.

Walter Benjamin fellowship
Rebecca Nagel has been awarded a Walter Benjamin fellowship from the German Research Foundation (DFG) for a period of 2 years. Come January 2022, she will be carrying out research at the University of St. Andrews in the UK in collaboration with Dr. Michael Morrissey. She plans to pair newly collected micro-meteorological data with data from the long-term research project of wild Soay sheep to test the hypothesis that incorporating fine-scale, individual-based environmental conditions into multivariate trait-fitness regression models will produce more robust predictions of selection.
Congratulations, Rebecca, and all the best!

Workshop: Individual recognition software Wildbook
Using crowdsourced images to enable continuous and automated monitoring of both population size and geographic range of amphibians and reptiles to establish effective conservation plans - sounds like a dream?
Within project A04, a software called Amphibian and Reptile Wildbook has been developed to do just that.
More information on the Wildbook project can be found on the homepage.
On Saturday, 05.03.2022, a workshop will be held to introduce this software. The workshop will be held in German. Here you find the program.
Cortisol levels and domiance rank
Cortisol response to an acute challenge is known to be repeatable and correlated with social behaviour in males of many mammalian species. Taylor Rystrom and colleagues have now investigated whether these patterns are also consistent in female guinea pigs (Cavia aperea f. porcellus).
Take a look at what Taylor and her colleagues discovered, here.
Behavioral Ecology paper on the effects of clerodanoids out
An inspiring study in which Sarah Paul & Caroline Müller demonstrate the importance and potential of studying agonistic intersexual interactions over non-reproductive resources. Learn more about the agonistic nibbling behaviour of turnip sawfly (Athalia rosae) here.
Collaborative research center on the individual niche has been extended
We are very happy to announce that our "NC³" enters its second funding phase. Over the next four years, we will continue to work in an interdisciplinary team of philosophers, theoretical biologists, statisticians, ecologists, evolutionary and behavioral biologists, to define and establish the niche concept at the level of the individual and to understand the ecological and evolutionary consequences.
New job announcements can be found here: NC³

Visit us at the Museum of Natural History in Münster!
We are very, very proud to present "Tierisch individuell", an exhibition all about animals chosing, conforming to and constructing their individual niches!
Update: The exhibition at the LWL-Museum für Naturkunde in Münster ended in October. "Tierisch individuell" will open again at the namu/Naturkundemuseum in Bielefeld in March 2022!
ERC Starting Grant
Congratulations to Toni Gossmann! He has won the European Research Council's prestigious Starting Grant. Toni will use this to continue unravelling the mysteries of DNA methylation, and how these can be inherited. We are thrilled and are looking forward to the next years working with Toni.
Paper on code availability draws wide attention
75% of ecological journals require code-sharing, but only 27% of articles comply with this rule, as a recent paper by Alfredo Sánchez-Tójar and colleagues recently showed. This result is now being widely shared and discussed.
Collaborative TREE paper out!
The conceptual paper from the NC³ cloud on molecular and physiological mediators has been published. For everything you want to know on the importance on infochemicals for choosing, conforming to and constructing of individualised niches, and for highly useful definitions of terms all around NC³!
Odyssey home
Corona has shut many doors - especially those of airports. We are very glad to have Rebecca Nagel back from her field trip to the Antarctic. Her journey home took 75 days, as she recently told the Bielefelder Zeitung.
Researching to improve animal welfare
Looking for an excellent in-depth science podcast (in German)? Hear Helene Richter explain recent developments on the 3 R (replace, reduce, refine) of animal use in research.
Helene covers a wide range of this fascinating topic in great detail, from the numbers of animals used in science and food production and the laws regulating this use, to the problem of reproducibility and current trends in animal welfare research. Head to WWUcast to listen.
Hormones may teach an old guinea pig new tricks
Group-living requires different social skills than living in pairs. Advantageous behavioural types developed under such different social conditions are regulated by hormones. Alexandra Mutwill and colleagues have now been able to show that guinea pig males can readjust their hormonal setup according to a new social situation even in adulthood.
Open synthesis attracts more attention
The open synthesis revolution continues! Alfredo Sánchez Tójar talked to Hertz 87,9 about the reproducibility crisis and the revolutionary solution he and others recently suggested.
Norbert Sachser's book in award-winning project at WWU
Münster University will see an exciting series of public events in the next winter term. A lecture series, discussion forum and poetry, art and science slams will all focus on animal behaviour, based on Norbert Sachser's recent book "Der Mensch im Tier" (The human animal). This is part of the "Eine Uni - ein Buch" (One university - one book) initiative of the Stifterverband für die Deutsche Wissenschaft. Münster University was one of ten to win the competition this year. This will be a great opportunity to discuss all things animal behaviour and animal welfare with the public. We are very much looking forward to all the events!
Re-thinking the scientific environment for faster, safer results
Literature reviews and meta-analyses have long been plagued by publication bias and other problems. This week, Dr Alfredo Sánchez-Tójar and 21 co-authors published a far-reaching suggestion to revolutionise the way primary researchers and synthesists work. They suggest creating open synthesis communities where primary researchers and synthesists work hand in hand, and where synthesis is recognized as the end goal and updated continuously. "Bridging the divide between primary researchers and synthesists will lead to less research waste, more collaboration, faster research progress and better engagement."
