Can high biodiversity and agricultural productivity be reconciled? A community model of the bird–arthropod food web in African cocoa agroforestry indicates that low-intensity farming practices favour certain bird species and enhance the abundance of potential pollinators. doi.org/10.1002/eap....

On the train back home, still buzzing from some great days at @vogelwarte.bsky.social where Hans Schmid wrote "Getrennte Wege" - a classic synthesis of Honey Buzzard migration. A quarter century later the species has revealed a few more, but still not all of its migratory "Geheimnisse". #ornithology

What looked like a hearing organ on a tiny stinkbug’s leg turned out to be something far stranger: a fungal nursery that mother bugs use to coat their newly laid eggs in protective symbiotic hyphae, shielding their offspring from parasitic wasps.
