“…Euterpe edulis is a shade tolerant species that does not grow in gap openings and does not resist frost (Gatti et al . ). Because the lowest winter temperatures are often registered in the lower elevations of the PNI, palmital forests grow in high elevation sites (Gatti et al .…”

Spatial Pattern of Pindó Palm (Syagrus romanzoffiana) Recruitment in Argentinian Atlantic Forest: The Importance of Tapir and Effects of Defaunation

Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large-seeded plants, for instance, depend on large and endangered vertebrates for seed dispersal. In some Semi-deciduous Atlantic Forests, endangered tapirs (Tapirus terrestris) are major dispersers of pind o palms (Syagrus romanzoffiana). Here, we compare recruitment patterns of pind o palms between protected and disturbed (defaunated) Atlantic Forest areas in Argentina and evaluate the potential consequences of the lack of the main disperser for pind o palm regeneration. We analyzed the number and spatial pattern of pind o adults, offspring, and tapir dung piles within ten plots established in an area spanning tapir latrines inside Iguaz u National Park and in a fragmented forest area outside the park where tapir is locally extinct. In both areas, we evaluated recruitment levels beneath 24 adult palms in circular plots centered on adult stems. We found lower pind o palm recruitment outside the park where offspring tended to be aggregated around adult palms. In contrast, in Iguaz u National Park offspring were spatially associated with tapir dung-piles, in which most offspring were registered. Recruitment under adults was higher outside the park suggesting a lower rate of seed removal in disturbed areas. Our results show that tapir dispersal promotes higher recruitment levels of pind o offspring and shapes their spatial pattern, breaking the spatial association with adult (presumably maternal) palms. These results are useful for predicting the impact of local tapir extinction on this palm.Abstract in Spanish is available in the online version of this article.

“…Because the lowest winter temperatures are often registered in the lower elevations of the PNI, palmital forests grow in high elevation sites (Gatti et al . , ). These sites usually contain well drained soils and may also differ in the availability of specific nutrients or other physical properties.…”

“…Spatial distribution patterns of plant species are crucial to determine the structure and dynamics of populations and communities, as they reflect environmental conditions and ecological requirements of species as well as dispersion and extinction processes (Gatti et al, 2008;Svenning, 2002;Tilman and Kareiva, 1997).…”

“…These moist subtropical forests maintain high photosynthetic rates during most time of the year because many tree species are evergreen and the winter period during which the deciduous canopy species drop their leaves is short and with infrequent subzero air temperatures (Gatti et al, 2008;Tan et al, 2012;Cristiano et al, 2014). Changes in land use, particularly the replacement of native forests by tree plantations may have an impact not only on the water balance but also on the carbon balance at a regional level.…”
