🌐🌴 Current global hunting threat maps treat species as equally at risk everywhere in their range. We attempted to address this by combining where hunters actually go with which species are most likely to be targeted and least able to cope, for 6k+ trop. birds and 4k+ mammals: doi.org/10.32942/X24...

Body mass–abundance relationships reveal uneven global energy distribution across body size classes in vertebrates
The relationship between species body mass and abundance (MAR-SPP) is a fundamental feature of ecosystems, reflecting whether energy is accumulated in few large organisms or dispersed amongst several ...

In a recent paper @pnas.org, we found that the world’s oceans sort into six recurring “food-web types” shaped by temperature, productivity, and depth—functionally alike even when the species aren’t. A new baseline for tracking climate change. Check our video abstract: www.youtube.com/watch?v=nAv2...

👉 Investigadores descubren que los depredadores no son minoría. El estudio de más de un millón de especies terrestres desafía la idea clásica de la pirámide de la biodiversidad. Nos lo cuenta uno de sus autores, @miguelbaraujo.bsky.social (@mncn-csic.bsky.social):
Más depredadores de lo esperado: la pirámide de la biodiversidad es más bien un cuadrado

Some argue protected areas in fire-prone landscapes can undermine forest carbon (fuel build-up → higher fire risk). This paper shows Spanish protected areas consistently outperform comparable unprotected lands, strongest in National Parks. iopscience.iop.org/article/10.1...

El calentamiento oceánico provoca un descenso de la cantidad de peces del 20% anual - EFE
El calentamiento crónico y prolongado que sufren los mares está detrás del descenso de casi el 20 por ciento anual de la biomasa de peces.

New paper out in collab with amazing Brazilian researchers! By sampling 30 vegetation plots along a hunting pressure gradient, we show that sapling recruitment of large-seeded animal-dispersed species is consistently lower in overhunted forests. onlinelibrary.wiley.com/doi/10.1002/...
Cascading Effects of Overhunting on the Functional Tree Composition of Amazonian Forests
We examined how overhunting-induced defaunation affects the functional composition of tropical tree communities in western Brazilian Amazonia. Using a robust, spatially replicated dataset from 30 for...

Great energy today at the MNCN-CSIC Biogeography & Global Change Annual Meeting at Ventorrillo! Let’s keep pushing scientific boundaries and driving meaningful change together @mncn-bgcg.bsky.social @mncn-csic.bsky.social
Great annual meeting of our @mncn-bgcg.bsky.social biogeography and global change group and departament at the @mncn-csic.bsky.social biological station of El Ventorrillo. Good to meet new members and witness the extraordinary work of PhD students and Postdocs. Thanks for the organizers.

Finally it is here! 🥳 We simulated 280 virtual species under current and future scenarios testing multiple background levels. Background optimization can improve model performance for current scenarios, but not so much for future ones. Also 5% of the study area sampled as bg seems to be the best.

We show that marine communities around the world exhibit trophic convergence in similar environments — a global pattern echoing what we also found on land. This challenges classic biogeographic models and opens new doors for predicting biodiversity responses to change. www.pnas.org/doi/10.1073/...

Este paper de la tesis de Fernando Hurtado muestra que la mayoría de especies coocurren o son neutrales a distintas escalas. La exclusión competitiva es menos común, y hasta el 7% de las especies analizadas ocurren juntas más en cojines de musgo que a escala regional @mncn-bgcg.bsky.social 🧪👇#NICED
Macroclimatic niche similarity and species relatedness shift their influence on species co‐occurrence in bryophyte forest communities across scales
The relationship between epiphytic bryophyte species associations changes with scale. Macroclimatic niche similarity strongly influences co-occurrence globally but less so at smaller scales. Most spe...

A great paper by @bryonyblades.bsky.social shows that mobilising data from recent surveys by taxonomists and other specialists complements the spatial and climatic coverage and reduces bias in data on insect distributions from @gbif.org. @cristinaronquillo.bsky.social @mncn-bgcg.bsky.social 🌐🧪
Mobilisation of Data From Natural History Collections Can Increase the Quality and Coverage of Biodiversity Information
Data gaps on the Global Biodiversity Information Facility (GBIF) are well described for the tropics and invertebrates, and here, we show that biases in spatial coverage translate to undersampling of ....
