Combining chronosequences and multi-census approaches to understand patterns of succession in subtropical montane forests of NW Argentina
Question
How does the diversity of successional forests evolve with stand age, and to what extent do permanent plots validate the previously studied successional patterns of tree diversity and composition observed through chronosequences? To evaluate the role of successional forests as reservoirs for many species, it is essential to examine how biodiversity recovers with the age of the stand. We studied patterns of taxonomic and functional diversity, as well as species composition during forest succession, by combining chronosequences and permanent plot monitoring.
Location
Subtropical montane forests in NW Argentina.
Methods
We used data from two chronosequences of plots monitored for 30 years in lower and upper montane forests dominated by native trees (LMF-Native and UMF-Native), and one chronosequence of plots dominated by the exotic tree Ligustrum lucidum, monitored for 10 years in low montane forests (LMF-Invaded). We analyzed changes in taxonomic (species richness, Shannon diversity, Simpson diversity) and functional diversity, as well as composition with forest age.
Results
Taxonomic and functional diversity increased between 30 and 70 years of succession in LMF-Native and UMF-Native. Successional LMF-Native forests reached the diversity of mature forests earlier than UMF-Native. In LMF-Invaded, taxonomic and functional diversity decreased in the same period because of the increasing dominance of the exotic species Ligustrum lucidum. In non-invaded chronosequences (LMF-Native and UMF-Native) we observed a convergence towards the composition of mature forests; however, each successional forest kept its identity for 30 years.
Conclusions
Diversity and composition followed different successional trajectories depending on the type of forest. We found that successional patterns, such as changes in taxonomic and functional diversity, predicted with the chronosequence approach, were confirmed with data from plot monitoring. The effects of pre-abandonment conditions persist in the diversity and composition of successional forests monitored between 10 and 30 years.
期刊介绍：
The Journal of Vegetation Science publishes papers on all aspects of plant community ecology, with particular emphasis on papers that develop new concepts or methods, test theory, identify general patterns, or that are otherwise likely to interest a broad international readership. Papers may focus on any aspect of vegetation science, e.g. community structure (including community assembly and plant functional types), biodiversity (including species richness and composition), spatial patterns (including plant geography and landscape ecology), temporal changes (including demography, community dynamics and palaeoecology) and processes (including ecophysiology), provided the focus is on increasing our understanding of plant communities. The Journal publishes papers on the ecology of a single species only if it plays a key role in structuring plant communities. Papers that apply ecological concepts, theories and methods to the vegetation management, conservation and restoration, and papers on vegetation survey should be directed to our associate journal, Applied Vegetation Science journal.
