What factors shape genomic diversity in birds?

Based on the Proceedings B paper by Anna Brüniche-Olsen, Kenneth Kellner and their colleagues | #ornithology

Great write up of our study showing that both extrinsic factors (e.g. habitat availability) and intrinsic traits (e.g. body mass and diet) play important roles in shaping patterns of genomic diversity in birds 🦜 🧬 🌏

Global opvarmning kan drive os mod iskoldt kollaps Katherine Richardson og kolleger advarer i nyt studie mod de store havstrømmes kollaps. Og taler for hurtige adfærdsændringer og cirkulær økonomi

"Det er fuldstændig naivt at tro, at vi kan klare os med teknologi. At forlade sig på teknologier, der ikke eksisterer, er galimatias", siger Katherine Richardson ovenpå nyt studie om global opvarming og tipping points 🌎 #dkvid #dkgreen @information.dk

The risk of a hothouse Earth trajectory Earth’s climate is now departing from the stable conditions that supported human civilization for millennia. Crossing critical temperature thresholds may trigger self-reinforcing feedbacks and tipping dynamics that amplify warming and destabilize distant Earth system components. Uncertain tipping thresholds make precaution essential, as crossing them could commit the planet to a hothouse trajectory with long-lasting and potentially irreversible consequences.

Ny IPBES-rapport: Biodiversitetskrisen vil koste virksomheder dyrt Ny rapport fra IPBES advarer om, at biodiveristetstab truer erhvervslivets fremtid. Rapporten bør være et stort »wake-up call«, lyder det fra Danmarks repræsentant i IPBES.

Fantastic to see #IPBES12 has approved the #BizBiodiversity Assessment Report.

My congratulations to all the @ipbes.net experts, partners and countries for coming together to deliver this important result - a big win #ForPeopleForPlanet.

Stay tuned for the report launch tomorrow. More details ⤵️

Environmental data justice is key for developing more effective area-based conservation approaches Nature Reviews Biodiversity, Published online: 27 January 2026; doi:10.1038/s44358-025-00126-wScientists disagree about area-based conservation’s role in addressing biodiversity loss. This Perspective examines how conservation scientists, land systems scientists and political ecologists approach these debates differently and argues that environmental data justice frameworks can bridge epistemic divides, helping researchers to develop more effective and equitable conservation interventions.

This infographic from the World Economic Forum shows global risks ranked by severity over two time periods: 2-year (short term) and 10-year (long term). The title reads "Global risks ranked by severity" with the WEF logo in the top right corner. The chart is divided into two columns, with risks color-coded into four categories: Environmental (green), Geopolitical (orange), Societal (red), and Technological (purple). In the short term (2 years), the top risks are: Geoeconomic confrontation Misinformation and disinformation Societal polarization Extreme weather events State-based armed conflict In the long term (10 years), the ranking shows: Extreme weather events Biodiversity loss and ecosystem collapse Critical change to Earth systems Misinformation and disinformation Adverse outcomes of AI technologies Both columns continue to rank risks through position 10, with environmental concerns featuring more prominently in the long-term outlook. The source is cited as "World Economic Forum Global Risks Perception Survey 2025-2026."

New World Economic Forum Global Risks data provides a stark warning: While short-term crises dominate headlines, "Biodiversity loss and ecosystem collapse" jumps to the 2nd highest risk over the 10-year horizon.

The long term is sooner than we think. Science-based policies via IPBES are crucial.🌍
