In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The

Restoring habitat corridors between fragments and continuous forests can potentially counter the effects of isolation, especially in tropical forests where species sensitivity to fragmentation is high. The ability of restored linear habitats to absorb natural disturbance in inimical surroundings potentially reflects resilience, an important aim of ...

Fire effects on the composition of soil seed bank and soil properties in Iran
Abstract Fire is a frequent phenomenon in rangelands and because of its complicated and different effects on natural ecosystems, it has great importance. Awareness of such fire effects on vegetation cover in point of rangeland management after fire is important and helps better understanding and sustainable management of rangelands.

Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Diverging repeatomes in holoparasitic Hydnoraceae uncover a playground of genome evolution
Summary The transition from an autotrophic to a heterotrophic lifestyle is associated with numerous genomic changes. These often involve large genomic alterations, potentially driven by repetitive DNAs. Despite their recognized role in shaping plant genomes, the contribution of repetitive DNAs to parasitic plant genome evolution remains largely ...
