- Abstract
In order to assess the impact of seed removal and seedling establishment for four species of pines, we designed experiments with and without the exclusion of seed removers in three vegetation types (pine forest, oak-alder forest, and subalpine grassland). Seed removal was significantly different between species of pines ( P < 0.01), as was the interaction between the vegetation types and category of exclusion (remover) ( P < 0.0001). The significant difference in terms of seed removal was between P. patula and P. montezumae (33.0 and 17.9%, respectively). Seed removal was significant between pine forest-without exclusion (20.0%) versus oak-alder forest-without exclusion (7.0%). There was significant interaction between seedling establishment of the pine species and vegetation type ( P < 0.0001). Highlighting differences between the pine forest- P. teocote (84.1%) versus oak-alder forest- P. patula (19.0%), oak-alder forest- P. pseudostrobus (45.0%), pine forest- P. patula (20.2%), pine forest- P. pseudostrobus (45.6%), subalpine grassland- P. montezumae (24.3%), subalpine grassland- P. patula (27.9%), and subalpine grassland- P. pseudostrobus (17.5%). The impact of the food preferences of rodents and other granivores for P. patula and P. pseudostrobus seeds, as well as the poor survival of seedlings of these species in the pine and oak-alder forest are both factors which may explain the dominance of P. teocote in the study region.
