Locomotion Reveals Contrasting Responses in Body Mass‐Scaling of Metabolic Rates Between Winged and Wingless Arthropods
We test how activity and locomotor mode affect metabolic scaling in arthropods. Only winged insects show increased scaling with activity, likely due to flight-related thermal and biomechanical factor...

We find that adherence of 180 soil food webs to the energy equivalence rule strongly depends on the measure of energy use, trophic level, and food web structure. www.nature.com/articles/s41...

Really nice to read those 🤩

I've finally got around to curating a selection of films about the #climate crisis 🎥

There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️

They make excellent resources for classrooms, lecture halls, or community cinema's 🎬

Super cool experimental study demonstrating how warming and species richness alter mass-abundance structure of ecological communities.
Does body size predict abundance the same way in all environments, as predicted by the Metabolic theory of Ecology? Our new study challenges this assumption. Read it here: 📄 doi.org/10.1111/ele....
Biodiversity modulates the cross‐community scaling relationship in changing environments
Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species ric...
