While root carboxylate exudation is a common P‐acquisition strategy in many plants, Poaceae generally release minimal amounts of carboxylates under P deficiency. In contrast, phytosiderophores are well‐known for their role in iron (Fe) acquisition in grasses, and emerging evidence suggests they may also participate in soil P mobilisation, potentially complementing or replacing carboxylate‐based strategies under P deficiency. However, the prevalence and significance of this strategy across native Poaceae in south‐western Australia remain unknown. </jats:list-item> <jats:list-item> We examined the carboxylate and phytosiderophore exudation of native grass species under different P availability, grown both in hydroponics (eight species) and in soil (six species) in glasshouse experiments.

PSF is frequently negative when plants grow in soil conditioned by individuals of their own species (conspecific PSF). If for a given species pair, both perform worse in their own relative to in each other's soils, such negative net pairwise PSF may contribute to species coexistence. PSF likely influences long‐term invasion success of alien plants: While recently introduced species may benefit from a release of soil antagonists, over time such may accumulate, resulting in increasingly negative PSF. </jats:list-item> <jats:list-item> We investigated the role of soil antagonists (mostly pathogens) and mutualists in shaping PSF across species from an early stage of invasion up to species that have resided in Germany for thousands of years.

In many plant–frugivore networks, ground‐dwelling vertebrates are the primary consumers of ripe fruits after they fall to the ground. Sudden fruit drop pulses triggered by extreme events (e.g. storms and cyclones) may drastically alter the timing and magnitude of fruit availability, potentially redistributing interaction opportunities across functionally diverse frugivores (i.e. seed dispersers and predators). However, the potential impacts of extreme events on plant–seed disperser mutualisms remain largely unexplored. </jats:list-item> <jats:list-item> In this study, we illustrate how concurrent extreme precipitation and wind events alter fruit drop dynamics and plant–frugivore interactions by combining continuous climatic data, fruit drop monitoring, controlled fruit‐offering experiments and a mechanistic simulation model.

Field experiments showed that these pulses enhanced short‐term fruit removal by both seed dispersers (mammalian carnivores) and seed predators (ungulates), but predators responded more strongly. Simulations further revealed that as extreme events became more frequent, intense and prolonged, and thus, the number of pulsed fruit drop days increased, the imbalance in fruit removal was amplified as the fruiting season progressed: while each pulsed fruit drop day raised disperser removal, it simultaneously increased predation, resulting in an overall ~4% reduction in seed dispersal throughout the fruiting season. </jats:list-item> <jats:list-item> <jats:italic>Synthesis</jats:italic> : These results underscore the profound, yet underappreciated, role of extreme weather events in reshaping the ecological dynamics of fruit drop and the balance between seed dispersal and predation in plant–frugivore networks.
