Competition, Drought, Season Length? Disentangling Key Factors for Local Adaptation in Two Mediterranean Annuals across Combined Macroclimatic and Microclimatic Aridity Gradients

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Using an large greenhouse experiment, we disentangled three key drivers for local adaptation along natural aridity gradients: competition, drought stress, and short season length. In this context, we are the first to combine a microclimatic and macroclimatic scale. Our results relate to ecological theory and climate change vulnerability.

Persistent inner tepals and wings protect developing seeds of Rheum nanum from insect herbivory in Central Asian cold deserts

open access: yesEcology and Evolution, Volume 14, Issue 8, August 2024.
Although the postdispersal function of fruit appendages has been reported, little is known about their protective/defensive functions. In this context, diaspores with appendages (persistent inner tepals and/or fruit wings) that experienced predispersal herbivory by insects in natural populations of Rheum nanum were investigated.
