I wrote about this beautiful paper. 🧬 Cyanobacteria exposed to shorter days (in the lab) "rewire" their membrane lipids to anticipate cold weather. When those cells are plunged into cold water, they have "two or three-times higher survival" than cells exposed to longer days. This discovery would be entirely unremarkable in mammals; we already know of many examples of animals that hibernate, migrate, or estivate in response to seasonal changes. But this study documents the first time that “photoperiod adaptations” have been observed in a single-celled organism. Cyanobacteria — an organism that divides in just six hours — is able not only to sense changes in the hours of daylight but also to use that information to adapt and prepare for weather far in advance.  The essay is published at Asimov Press!

For any researchers who are currently missing the Mosquito Taxonomic Inventory, some of the content has been fully revised, updated, and is being published next month (by CABI) in a book titled "Composition and Nature of the Culicidae (Mosquitoes)" by Ralph Harbach. It will be a must have title for anyone interested in mosquito systematics, bionomics, taxonomy, nomenclature and evolution. https://lnkd.in/enfJ3_De

🔬 Our new research article is published online! In our ongoing effort to highlight all of the parameters that can contribute to the overall profitability of two mealworm species, Alphitobius diaperinus (Panzer) and Tenebrio molitor L. (Coleoptera: Tenebrionidae) in mass-rearing scenarios, we evaluated the effect of feed particle size on the larval growth and feed utilization parameters of these important mealworms. ✅ Our research results suggest that a finely ground feed significantly impact the growth and development of A. diaperinus. Contrariwise, the larvae of T. molitor exhibited no discernible response to the various feed particle sizes that were evaluated. Congratulations to our team 🎉 Marianna Rigopoulou, Rumbos Christos, Christos Athanassiou 📎 Our open-access article is available online: https://lnkd.in/dAru8hZu

Dear behaviour of fish enthusiasts,  We intend on producing a special issue of Cybium (International Journal of Ichthyology, https://sfi-cybium.fr/en) focusing on the Behaviour of fish. It will be one of the four annual issues of the journal in 2025. The aim is to upgrade our present knowledge of the behaviour of fish by synthesising years of research and adding recent works. This special issue will consider a broad range of topics, from wild observations to experimental research. Articles might, for instance, introduce new methodologies to study behaviour in water conditions, study the behavioural impacts of rearing conditions and welfare, highlight the effects of abiotic or biotic factors on behaviour, or focus on specific aspects of species biology such as communication, reproduction or distribution in the wild.  If you are interested in participating by contributing a manuscript and/or assisting with the review process, contact Sébastien Alfonso and Tatiana Colchen, the special editors for this volume. We are looking forward to receive your contributions, Tatiana Colchen and Sébastien Alfonso for Cybium tatiana.colchen@univ-angers.fr cybiumsfi@gmail.com #callformanuscript #fishbehaviour

I presented my poster titled: "Competitive dynamics of two non-native grasses, cheatgrass (Bromus tectorum) and ventenata (Ventenata dubia), and cause for concern for secondary invasion in the Greater Yellowstone Ecosystem" at the Greater Yellowstone Ecosystem Biennial Science Conference in Big Sky, Montana. It was great to chat with folks about competition research in plants. For more information on my poster follow this link to my blog: https://lnkd.in/gg-5zxgy

Great contest for doctoral researchers who have been active in genetics, plant genetic resources and/or plant breeding! 🌱 Important to note: the defence of your doctoral thesis must date back less than two years 📆 Have a look at the details below 😊

Thanks to Prof. Ferrando and my BIO colleagues for involving me in this recently published work in Animals (Q1). Traverso, F.; Aicardi, S.; Bozzo, M.; Zinni, M.; Amaroli, A.; Galli, L.; Candiani, S.; Vanin, S.; Ferrando, S. New Insights into Geometric Morphometry Applied to Fish Scales for Species Identification. Animals 2024, 14, 1090. https://lnkd.in/dsSWFTDS The study focuses on applying geometric morphometry to fish scales for species identification. Two methods are used: landmark-based and outline-based. The outline-based method appears promising for future automation, while the landmark-based method achieved better results in species clustering. Analyzing scale shapes provides a cost-effective and potentially automatable alternative to molecular methods for species attribution. MDPI #MDPI https://lnkd.in/dTD5gE9j

Good to see this paper finally published. In the last years, there have been attempts to propose a range of changes to taxonomy & biological nomenclature that were considered inappropriate for different reasons. This appeal explains four main reasons for preserving the stability of biological nomenclature and is supported and signed by 1563 scientists (including myself). https://lnkd.in/gnq7uUb7

🌲 Exciting news for the dendrochronology community! A new dataset called UruDendro has been made publicly available, containing 64 scanned images of transverse sections of Pinus taeda trees from northern Uruguay. These images present various challenges for automatic ring detection, making it an ideal resource for developing and testing tree ring detection algorithms. The accompanying blog post introduces the Cross-Section Tree-Ring Detection (CS-TRD) method and evaluates its performance against manual ring delineation. The CS-TRD software achieved an average F-score of 89% and an RMSE error of 5.27px for the entire dataset in less than 20 seconds per image. This study offers a valuable addition to the dendrochronologist's toolkit for fast and cost-effective automatic ring detection in conifer species. Read the full paper here: https://bit.ly/4d4yRpe 🌲
