Es una señal de que el cambio climático no solo afecta a la planta sino a toda la red de relaciones que la rodea, incluidos los cultivos y la biodiversidad de nuestros campos. Para quien trabaja en agricultura o cuida un jardín, implica que las plagas y los polinizadores pueden reaccionar de formas inesperadas. El estudio es de un único sistema biológico, así que no se puede extender a todas las especies sin más pruebas.","quienFirma":"Institución no identificada en el resumen disponible","confianza":"preprint","consulta":null},"sello":{"hash":"f025aace3aa390a3b0f136957fe070ed10a93a031045b6aef71609f07c174e12","sello":"719bdb3500b2680a16c78075a73d9136291da7b5b2928dee33ff8ac042f34cea","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6583459,"aleatorio":"0a139b88186ff9ac4061b9ae2a2fd60d7a03c380f08f96a5b763a564cd5f8535","tiempo":"2026-10-25T13:26:30.000Z"},"nist":{"cadena":2,"pulso":1998923,"salida":"CAACCBC90B253254A2BA37D2F2DAD32D412D022A909309D40D4961AE24D8236EAD656C06ED2DE2604FB73EFC57434602CEDA74C12D692B1DB5605BA381C0ED58","tiempo":"2026-10-25T13:26:00.000Z"},"noAntes":"2026-10-25T13:26:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 25 13:26:59 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Climatic stress reshapes sex-specific multimodal floral phenotypes and interactions with a nursery pollinator across life stages","descripcion":"Background: Nursery pollination combines mutualistic and antagonistic interactions between plants and insects: adult insects provide pollination services, while their larvae consume plant reproductive tissues. Climatic stress may alter the benefits and costs for both partners by modifying plant phenotypes and their consequences for pollinator behaviour and offspring performance. These dynamics gain an additional layer of complexity in systems where both plants and insects have separate sexes, giving rise to sex-specific interactions and potentially divergent stress responses. Yet how climatic stress affects these specialized interactions remains unexplored.
