Abundance and richness of insect pollinators that fed on or collected the honeydew excreted by the giant willow aphid on invaded willows. Then, to assess associational effects, we compared the abundance and species richness of floral visitors with a potential pollinator role (hereafter pollinators) on S. chilensis located near and far away from the willow-aphid complex. https://rdi.uncoma.edu.ar/handle/uncomaid/19130 Fertilization practices have cascading effects on food webs, influencing both productivity and ecological balance Datos del manuscrito Fertilization practices have cascading effects on food webs, influencing both productivity and ecological balance https://rdi.uncoma.edu.ar/handle/uncomaid/18934 First Record of Flower Bud Galls in Senega (Fabales: Polygalaceae): The Case of S. salasiana and Their Effect on Plant Reproduction. We report the first case of flower bud galls in a species of the mainly American genus Senega (Polygalaceae), specifically in the South Andean Patagonian plant species S. salasiana. The galls were found to be induced by gall midges (Diptera, Cecidomyiidae) and mites (Acari). We also assessed their impact on plant reproduction by measuring the relationship between inflorescence density (number of inflorescences/plant cover) and gall abundance in two populations next to San Carlos de Bariloche, Patagonia, Argentina. Plant reproduction was negatively related to the number of galled inflorescences, suggesting that high levels of gall abundance strongly reduced plant reproductive success. Our study illustrates a novel case of flower galls in the genus Senega and highlights the negative impact of this type of herbivory on plant fitness. https://rdi.uncoma.edu.ar/handle/uncomaid/18898 A win–win for crops and ecology: biofertilizers enhance productivity without ecological cost Datos de ms.
