Better lighting can mean better biodiversity. LIB researchers & colleagues found that amber 1800 K LED lighting at railway stations attracted far fewer nocturnal insects than conventional lighting, offering a practical way to reduce light pollution. #LIBresearch © Ludreschl et al., CC BY 1/3

Every genome helps tell a species' story. Researchers generated a reference genome for the Eurasian woodcock (Scolopax rusticola), providing a valuable resource to study its evolution, population structure, and conservation. #LIBresearch © Paul Cools (iNaturalist), CC BY-NC 4.0 1/3

Why is science communication so difficult? A new perspective argues it's a "wicked problem" shaped by different expectations, values, and societal roles, not something solved by simply fixing public "deficits." #LIBresearch © Roedder & Weingart, CC BY 1/3

Protecting pollinators isn't just about saving species, it's also about protecting the places & pathways they depend on. Key Pollinator Areas and Buzz Lines offer a new framework to identify priority habitats & ecological corridors for Europe's wild pollinators. © Deiss et al., CC BY 1/3

Some of the world's largest iron ore deposits owe their existence to ancient photosynthesis. Ancient atmospheric oxygen, preserved in buried salts, later helped form major iron oxide-apatite deposits. #LIBresearch © Adobe Stock #972222846, Abinieks 1/3

Some of the world's most successful invaders are only a few centimetres long. A new reference genome for the eastern mosquitofish (Gambusia holbrooki) will help researchers study how this invasive fish spreads and adapts. #LIBresearch © Smithsonian Environmental Research Center, CC BY 1/3

The future of a fish population can depend on its very first days of life. Researchers investigated how Baltic herring embryos respond to changing temperatures, revealing how thermal tolerance during early development may shape survival in a warming sea. #LIBresearch © Fischbach et al., CC BY 1/3

Not all invasive insects are pests. Florida calligrapher (Toxomerus floralis), a flower-visiting hoverfly, is rapidly expanding across the Afrotropical region. Researchers traced its invasion history & explored how it adapts to new environmental conditions. #LIBresearch © Muller et al., CC BY 1/3

Facts become truly valuable when they keep their context. The Semantic Units Framework introduces a new way to represent scientific knowledge that preserves meaning, making research information easier for both humans and machines to understand and reuse. #LIBresearch © Vogt, CC BY 1/3

Evolution isn’t always a simple family tree. By applying genomic mixture models, researchers unraveled the long-standing evolutionary puzzle of the butterfly genera Calisto and Llorenteana, revealing a more complex history than previously recognised. #LIBresearch © Núñez et al., CC BY 1/3

Every genome is a new window into biodiversity. Researchers generated a reference genome for Dailognatha quadricollis, an East Mediterranean darkling beetle, opening new opportunities to study evolution and adaptation. #LIBresearch © Bolanakis et al., CC BY | photo: Dr Apostolos Trichas 1/3

Biodiversity doesn’t always arise through isolation. Genomic analyses of sailfin silversides from Sulawesi reveal that ancient and recent gene flow fueled their adaptive radiation, contributing to the evolution of unique forms within a single lake system. #LIBresearch © De Keyzer et al., CC BY 1/3

Museum collections are more than archives: they anchor species names. A new catalogue documents over 10,000 Cumacea type specimens from the Hamburg collection, improving access to a key resource for biodiversity research. #LIBresearch © Mercado-Salas et al., CC BY 1/3

Some of the most fascinating biodiversity is easy to overlook. A taxonomic review of the Korean dragon pseudoscorpions (Allochthonius) revealed three species new to science, highlighting how much diversity remains hidden among tiny, rarely seen arthropods. #LIBresearch © Jeong et al., CC BY 1/3

What does a shark look like before it hatches? Using synchrotron micro-CT scanning, researchers created detailed 3D images of embryonic development in the small-spotted catshark—revealing anatomical changes without damaging these delicate specimens. #LIBresearch © Escamilla-Veg, CC BY 1/2

#LIBresearch: Even tiny insects can leave traces across millions of years. Researchers described the first fossil member of the jumping plant-louse family Aphalaridae from the Miocene of southern Germany, offering a rare glimpse into their evolutionary history. © Serbina et al., CC BY 1/3

Tiny fossils can rewrite millions of years of evolutionary history. A new pseudoscorpion preserved in ~99-million-year-old Burmese amber represents the first known fossil of the family Chernetidae, pushing its fossil record back by at least 20 million years. #LIBresearch ©Willmott et al., CC BY 1/3

Scientific knowledge is only as useful as it is shareable. Rosetta Statements provide a new way to make research data both human-readable and machine-actionable, helping bridge the gap between scientists, databases, and knowledge graphs. #LIBresearch © Vogt et al., CC BY 1/3

How much biodiversity is still waiting to be discovered? A taxonomic revision of Southeast Asian scarab beetles revealed previously unrecognized diversity, including several species new to science hidden within museum collections and field material. #LIBresearch © Botjes et al., CC BY 4.0 1/3

Biodiversity hotspots can still hold remarkable surprises: Combining fieldwork, museum collections, DNA barcoding and climate modelling, researchers discovered a new spider genus and 11 new species in Brazil’s Caatinga and Cerrado. #LIBresearch © Huber et al., CC BY 1/3

In many social insects, the same genome can produce queens, workers, or males with very different roles. A new review explores how sex-determination pathways have been repeatedly adapted to shape the complex social systems seen in ants, bees & wasps. #LIBresearch © Adobe Stock, The physicist 1/3
