11. Long-lasting ecological legacies of reindeer on tundra vegetation
Sammanfattning : Reindeer can have strong effects on the plant species composition and functioning of tundra ecosystems, and often promote a transition towards a graminoid-dominated vegetation type. As a result, they influence many ecological processes, such as nutrient dynamics, soil biotic composition and functioning, and carbon storage. LÄS MER
12. Context dependency of plant – animal interactions
Sammanfattning : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. LÄS MER
13. Plant sex effects on biotic interactions in dioecious willow : plant sex-specific effects on interactions between Salix viminalis and its herbivores, pollinators and fungal disease
Sammanfattning : Sex in dioecious plants affects interactions between plant individuals and the organisms consuming them. Plant-herbivore interactions are affected by plant sex across many plant families, and plant-pathogen infections can be strongly sex-biased. LÄS MER
14. Circumpolar impacts of herbivores on Arctic tundra vegetation
Sammanfattning : Arctic tundra vegetation provides many ecological services that have implications for the global climate. However, the tundra biome is currently changing in response to increasing temperatures. Herbivores may mitigate some of these responses to warming through their impact on Arctic vegetation. LÄS MER
15. Molecular population genetics of inducible defense genes in Populus tremula
Sammanfattning : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.
