OPOSSUMS: THEIR IMPORTANCE AS SEED DISPERSERS IN ANDEAN FORESTS
Seed dispersal by frugivorous animals is an ecological process that influences the dynamics of plant species, the functioning of ecosystems and the restoration of degraded landscapes. The main animals involved in this interaction are species of birds, bats and various groups of non-flying mammals. In the mountain forests of northwest Argentina...

Seed dispersal by animals: ecological function and ecosystem service
A tree suggests that a seed once managed to germinate and establish itself in that place. A forest multiplies that idea indefinitely. For many tree species, the arrival of a seed in favourable conditions for germination depends on the intervention of animals that consume the fruits and mobilize the seeds without damaging them. Half of the known...

Interaction networks in the Anthropocene
FUNDING SOURCE: CONICET - PIP 574 (2023-2025) SUMMARY: We expect to find that the context of forest degradation affects the consumption and selection of fruits by frugivores, driven by foraging decisions aimed at balancing the macronutrient composition in their diet. We are evaluating the consequences of these foraging decisions on seed rain...

Native tree seed dispersal is favoured by the presence of invasive exotic plants that bear fruit at the same time
In a study carried out in the mountains in central Argentina (Vergara-Tabares DL, Blendinger PG, Tello A, Peluc SI, Tecco PA; Fleshy-fruited invasive shrubs indirectly increase native tree seed dispersal; Oikos https://onlinelibrary.wiley.com/doi/full/10.1111/oik.08311), we found that the fruiting of invasive exotic shrubs (different Pyracantha...
