Abstract

fetched live from OpenAlex

Ecological developmental genetics is the study of how ecologically significant traits originate in the genome and how the allelic combinations responsible are maintained in populations and species. Plant development involves a continuous feedback between growth and environment and the success of individual genotype x environment interactions determines the passage of alleles to the next generation: the adaptive recursion. Outbreeding plants contain a large amount of genetic variation, mostly in the form of single nucleotide polymorphisms (SNPs). One of the challenges of eco-devo is to distinguish neutral SNPs from those with ecological consequences. The complete genome sequence of Populus trichocarpa Torr. & A. Gray will be a significant aid in this endeavour. Occurring from California to Alaska, this is the first ecologically 'keystone' species to be sequenced. It has a rich natural history and is an obligate outbreeder. The individual sequenced, Nisqually-1, appears to be heterozygous on average about every 100 bp over the c. 500 million bp of the genome. Overlaid on this within-individual variation is some ecologically based between-individual genotypic variation evident across the distribution of the species. The synthesis of information from genomics and ecology is now in prospect. This 'ecomolecular synthesis' is likely to provide a rich insight into the genomic basis of plant adaptation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
