Long-term seedling and small sapling census data from the Barro Colorado Island 50 ha Forest Dynamics Plot, Panama
<p>Tropical forests are well known for their high woody plant diversity. Processes occurring at early life stages are thought to play a critical role in maintaining this high diversity and shaping the composition of tropical tree communities. To evaluate hypothesized mechanisms promoting tropical tree species coexistence and influencing composition, we initiated a census of woody seedlings and small saplings in the permanent 50-ha Forest Dynamics Plot (FDP) on Barro Colorado Island (BCI), Panama. Situated in old-growth, lowland tropical moist forest, the BCI FDP was originally established in 1980 to monitor trees and shrubs ≥1 cm diameter at 1.3 m above ground (dbh) at ca. 5-yr intervals. However, critical data on the dynamics occurring at earlier life stages were initially lacking. Therefore, in 2001 we established a 1-m<sup>2</sup> seedling plot in the center of every 5 x 5 m section of the BCI FDP. All freestanding woody individuals ≥20 cm tall and <1 cm dbh (hereafter referred to as seedlings) were tagged, mapped, measured, and identified to species in 19,313 1-m<sup>2</sup> seedling plots. Because seedling dynamics are rapid, we censused these seedling plots every 1–2 years. Here we present data from the 14 censuses of these seedling plots conducted between the initial census in 2001 to the most recent census, in 2018. This data set includes nearly 1M observations of ~185,000 individuals of >400 tree, shrub, and liana species. These data will permit spatially-explicit analyses of seedling distributions, recruitment, growth, and survival for hundreds of woody plant species. In addition, the data presented here can be linked to openly-available, long-term data on the dynamics of trees and shrubs ≥1cm dbh in the BCI FDP, as well as existing data sets from the site on climate, canopy structure, phylogenetic relatedness, functional traits, soil nutrients, and topography.</p>
Data from: Divergent mechanisms of reduced growth performance in Betula ermanii saplings from high-altitude and low-latitude range edges
<p><span>The reduced growth performance of individuals from range edges is a common phenomenon in various taxa, and considered to be an evolutionary factor that limits the species' range. However, most studies did not distinguish between two mechanisms that can lead to this reduction: genetic load and adaptive selection to harsh conditions. This study investigated the climatic and genetic factors underlying the growth performance of <em>Betula ermanii</em> saplings transplanted from 11 populations including high-altitude edge and low-latitude edge population using RAD-seq analysis.</span></p> <p>For 11 B. ermanii populations in wide-latitude range of Japan, we estimated gene diversity, nucleotide diversity, <span>the coefficients of linkage disequilibrium, genetic differentiation between populations, population structure as well as the relatedness coefficient from SNPs. As a result, the low-latitude edge population exhibited a high level of linkage disequilibrium, low genetic diversity, a distinct genetic composition from the other populations, and a high relatedness coefficient.</span></p> <p><span>This data contains two SNPs datas (vcf files) used in these analysis. We analyzed SNPs data separately for 8 planting sites. Then each tarball contains 8 separate vcf files. One tarball named "vcfAfterFiltering" contains vcf files after SNP filtering steps used for the calculation of the coefficients of linkage disequilibrium. Another tarball named "vcfAfterLDPruning" contains vcf files after SNP filtering and before LD-based pruning used for the calculation of other genetic parameters.</span></p>
