Tree species, diameter, and canopy class records for 4-paired plots in Black Rock Forest, NY, since 1931.
Black Rock Forest maintains eight long-term forest monitoring plots in Cornwall, NY. Four pairs of plots were established in 1931 to compare thinning treatments to nearby control plots. Four plots are approximately 0.25 acres and the other four are 0.1 acres. Tree species, diameter at breast height, height and canopy class have been measured on all stems greater than 1 inch in diameter since 1931. Plots were revisited every five years until the 1990s and annually after 1994.

Selection shapes the genomic landscape of introgressed ancestry in a pair of sympatric sea urchin species
<p>A growing number of recent studies have demonstrated that introgression is common across the tree of life. However, we still have a limited understanding of the fate and fitness consequence of introgressed variation at the whole-genome scale across diverse taxonomic groups. Here, we implemented a phylogenetic hidden Markov model to identify and characterize introgressed genomic regions in a pair of well-diverged, non-sister sea urchin species: <em>Strongylocentrotus</em> <em>pallidus</em> and <em>S. droebachiensis</em>. Despite the old age of introgression, a sizable fraction of the genome (1% - 5%) exhibited introgressed ancestry, including numerous genes showing signals of historical positive selection that may represent cases of adaptive introgression. One striking result was the overrepresentation of hyalin genes in the identified introgressed regions despite observing considerable overall evidence of selection against introgression. There was a negative correlation between introgression and chromosome gene density, and two chromosomes were observed with considerably reduced introgression. Relative to the non-introgressed genome-wide background, introgressed regions had significantly reduced nucleotide divergence (<em>d</em><sub>XY</sub>) and overlapped fewer protein-coding genes, coding bases, and genes with a history of positive selection. Additionally, genes residing within introgressed regions showed slower rates of evolution (<em>d</em><sub>N</sub>, <em>d</em><sub>S</sub>, <em>d</em><sub>N</sub>/<em>d</em><sub>S</sub>) than random samples of genes without introgressed ancestry. Overall, our findings are consistent with widespread selection against introgressed ancestry across the genome and suggest that slowly evolving, low-divergence genomic regions are more likely to move between species and avoid negative selection following hybridization and introgression.</p>
