Digest: Local adaptation at close quarters*

Close Yet Distinctive Domain Adaptation

Domain adaptation is transfer learning which aims to generalize a learning model across training and testing data with different distributions. Most previous research tackle this problem in seeking a shared feature representation between source and target domains while reducing the mismatch of their data distributions. In this paper, we propose a close yet discriminative domain adaptation metho...

Niche partitioning between close relatives suggests trade-offs between adaptation to local environments and competition

Niche partitioning among close relatives may reflect trade-offs underlying species divergence and coexistence (e.g., between stress tolerance and competitive ability). We quantified the effects of habitat and congeneric species interactions on fitness for two closely related herbaceous plant species, Mimulus guttatus and Mimulus laciniatus, in three common habitat types within their sympatric r...

Genetic basis of adaptation in Arabidopsis thaliana: local adaptation at the seed dormancy QTL DOG1.

Local adaptation provides an opportunity to study the genetic basis of adaptation and investigate the allelic architecture of adaptive genes. We study delay of germination 1 (DOG1), a gene controlling natural variation in seed dormancy in Arabidopsis thaliana and investigate evolution of dormancy in 41 populations distributed in four regions separated by natural barriers. Using F(ST) and Q(ST) ...

A Close Look at Proteins

Proteins, macromolecules of almost unmatched complexity, display highly specific functionalities only when folded into a distinct three-dimensional (3d) configuration. Protein folding, a complex self-assembly process, thus links the protein’s functionality to the atomic arrangement of the peptide chain. Consequently the protein’s three-dimensional shape as well as its peptide sequence are of pi...
