🌊🐟 Did you know that the North Sea houting is found exclusively in Denmark? 🐟🌊 But actually, there has been a long-standing debate about whether the North Sea houting is at all distinct from the European lake whitefish, which inhabits several countries in Europe. In a new study, PhD student Aja Tengstedt and Professor Michael Møller Hansen sequenced and analyzed the entire genomes from both North Sea houting and European lake whitefish individuals. The results revealed interesting new insights into the evolutionary history of the North Sea houting. Key Findings: ⏳ Ancient Origin: The North Sea houting is approximately 7,500 years old! It diverged from the nearest population of European Lake whitefish 7,500 years ago. This is much earlier than indicated by previous studies based on few genetic markers. 🌊 Unique Adaptation: The North Sea houting has unique genetic variation that allows it to survive in high salinity seawater. This adaptation enables it to thrive in the Wadden Sea, unlike the European lake whitefish. 🧬 Inbreeding Challenge: The North Sea houting is threatened by inbreeding, with an inbreeding coefficient of ~10%. Although still relatively low, some of this inbreeding is recent, posing a significant challenge for future conservation efforts. 💡 The findings underscore the irreplaceable nature of the North Sea houting, highlighting the urgency of its conservation. Moreover, this study demonstrates the power of modern genome-based methods in addressing crucial questions for conservation strategies💡 Want to know more?

I’m so pleased to announce that the first paper from my PhD research has been published in FEMS Microbiology Ecology! 📝 Arctic cyanobacterial mat community diversity decreases with latitude across the Canadian Arctic ❄🔬 Read it here (open access): https://lnkd.in/ee5RaZ8r Summary: Cyanobacterial mats are complex microbial communities commonly found in polar freshwater systems. Our study explored the diversity within these mats across a latitudinal gradient spanning the Canadian Arctic, from subarctic taiga to the High Arctic ice shelves. We discovered a reduction in microbial diversity with increasing latitude. These findings underscore the sensitivity of microbial communities to environmental changes and their significance in monitoring Arctic biodiversity. Huge thanks to my supervisors, co-authors, and colleagues for all the help and support these last few years!

🌿 Imagine a plant with DNA longer than Big Ben is tall! The tiny New Caledonian fork fern, Tmesipteris oblanceolata, has the largest genome on Earth, stretching over 100 meters—more than 50 times that of humans! 🌏🌱 Researchers from the Royal Botanic Gardens, Kew, and the Institut Botànic de Barcelona (IBB-CSIC) in Spain uncovered this record-breaking find, dethroning the Japanese plant Paris japonica, which held the title since 2010. This discovery raises an intriguing question: Is having a larger genome an evolutionary advantage? 🤔 Dive into the article below to find out 👇 #interesting #biotech

🎣 Excited to share the research of ESR Francesca Conti on "The Effect of Light on Daily Rhythms of Thermal Preference in Astyanax mexicanus"! 🌡️🐟 The goal of the study is to evaluate whether there are daily rhythms in temperature selection in this fascinating fish species, which has evolved in an arrhythmic environment. Astyanax mexicanus, the cavefish, offers unique insights into how organisms adapt to extreme conditions.

Happy #ForamFriday, #FossilFriday Did you know… How extremophile benthic foraminifera look like under the microscope and what they eat?  ❓ Little is known about mechanisms allowing agglutinated and thecate (i.e., organic-walled) foraminifera associated with extreme environments to survive. Rohret and Bernhard (2024) present the first ultrastructural analysis of allogromids, a basal group of organic-walled thecate foraminifera, from seeps. 🔬 The authors make cytological observations of organic-walled and agglutinated monothalamids and milioline tubothalamids collected from sulfur-oxidizing microbial mats of Gulf of Mexico hydrocarbon seeps. 😮 Most allogromids contained numerous ingested bacteria. Saccaminids had abundant phagocytosed bacteria, indicating foraminiferal activity in seeps. A porcelaneous tubothalamid contained phagocytosed bacteria of one morphology. Increasing our knowledge of the cytology and ecology of these modern representatives of early-evolving foraminifera could help elucidate their 🧐 evolutionary history.

Did you know what idea is Charles Darwin most famous for? Charles Darwin is primarily renowned for his theory of evolution by natural selection. This groundbreaking theory, expounded in his seminal work "On the Origin of Species" published in 1859, revolutionized our understanding of the diversity and development of life on Earth. Darwin proposed that species evolve over time through a process of natural selection, where organisms with traits better suited to their environment are more likely to survive and reproduce, passing on these advantageous traits to their offspring. This idea fundamentally changed the way we view the natural world and laid the foundation for modern biology. 🌿🔬 #CharlesDarwin #Evolution #didyouknow #sciencetrivia https://lnkd.in/g635swNp .

🌿 Did you know the tiny New Caledonian fork fern holds the record for the largest genome on Earth? 🌏 Its DNA, if unraveled, would stretch over 100 meters—more than 50 times that of humans! 😲 This fern, Tmesipteris oblanceolata, has dethroned the Japanese flowering plant Paris japonica, which held the record since 2010. Researchers from the Royal Botanic Gardens, Kew, and the Institut Botànic de Barcelona (IBB-CSIC) in Spain made this incredible discovery. It's fascinating to think that this unassuming plant, often overlooked, can carry such a monumental amount of genetic information. Discover more about this incredible find and what it means for our understanding of plant biology in the article below.🌱📖

"Half-Earth: Our Planet's Fight for Life" is the third #book of E. O. Wilson's Anthropocene Epoch series. The renowned biologist advocates for committing half of the planet's surface to #nature and #biodiversity. This is crucial to stop the mass extinction of species (The Sixth Extinction) for the sake of future generations. I summarized my key takeaways in the attached, and below are the links to the earlier notes from the first two books in the series: 1. "The Social Conquest of Earth" (https://lnkd.in/gk3aDU8i) 2. "The Meaning of Human Existence" (https://lnkd.in/g3FaBmYf) #biology #biodiversity #sustainability
