ABSTRACT Biological invasions are a significant driver of global biodiversity decline in the Anthropocene. The success plant often depends on mutualistic relationships, such as animal‐mediated seed dispersal. While role birds dispersing invasive plants is well documented, involvement mammals new ecosystems remains largely unclear. In mountains Central Argentina, Pyracantha species among most prominent plants, and their dispersal by has been extensively studied. this study, we assessed within novel assemblage (comprising native, invasive, domestic species) process angustifolia P. crenulata shrubs. Specifically, identified which mammal legitimate dispersers, evaluated impact germination, determined where they deposit seeds using combination observational experimental approaches. Through camera traps faecal analyses, following consuming fruits: (1) species: cattle horses; (2) native grey fox, common hog‐nosed skunk, collared peccary; (3) European hare, wild boar, deer (red or spotted deer). We included two additional (i.e., peccaries brown brocket deers) to perform germination trials due presumably frugivorous behaviour. experiment revealed that ingestion captive horses, foxes, peccaries, deer, red exotic enhanced germination. Principal Component Analysis indicated no specific association between deposition sites, suggesting non‐directed This research highlights emergence mutualisms anthropogenic systems may influence community structure through promotion invasions.

Abstract Seed dispersal by birds constitutes an essential mechanism for ornithochorous exotic plants to successfully invade a new system. New biotic associations with native might facilitate the upward spread of from foothills into high mountains. However, environmental changes associated elevation are known drive in bird assemblages, and it is not clear how impact seed service invaders. We evaluated frugivorous assemblages one shrubs ( Cotoneaster franchetii , Rosaceae) broadest range among woody invaders Córdoba Mountains (Argentina). quantified frugivory interactions (including absolute proportional fruit consumption dispersers, pulp consumers, predators) using 4‐h observations focal C. distributed across low‐elevation, mid‐elevation, high‐elevation sites (700, 1100, 1800 m a.s.l., respectively; 15 individuals per elevational band site elevation). disperser richness was highest at low‐ mid‐elevation (three species vs. site), but (39.1%, 88 seeds 7.7%, 20 low‐elevation).

In mountain system, single abundant generalist disperser, rather than species, can uphold effective invasive shrub. This pattern may such higher ranges, thereby promoting invasion other upper elevations.

Abstract Plant species phenology is an important driver of invasions in seasonal climates. The non‐natives generally uncoupled from that native species. Grasses cover a large proportion the land surface and are invaders around world. Interestingly, non‐native grasses could be modulated by different metabolic pathways. We aimed to compare vegetative reproductive invasive C₄ with coexisting C₃ explore relationship between climate. recorded onset, duration synchronicity (flowering fruiting) during 1 year.
