A Proteome-Scale Map of the Human Interactome Network
The map uncovers significant interconnectivity between known and candidate cancer gene products, providing unbiased evidence for an expanded functional cancer landscape, while demonstrating how high-quality interactome models will help "connect the dots" of the genomic revolution.

Analysis of whole‐genome data in a system where two bird species hybridize despite their relatively high background genetic differentiation and past ecological divergence highlights the value of considering the landscapes of both genome‐wide introgression and divergence when characterizing the evolutionary forces that drive speciation.
Relationship of phenotypic variation and genetic admixture in the Saltmarsh–Nelson's sparrow hybrid zone
It is concluded that the discrimination of pure and hybrid individuals is not possible in the absence of genetic data, which has implications for conservation of pure populations, as extensive backcrossing throughout the hybrid zone may present challenges for monitoring pure species identified by morphology alone.
Fine-Scale Population Structure and Asymmetrical Dispersal in an Obligate Salt-Marsh Passerine, the Saltmarsh Sparrow (Ammodramus caudacutus)
The genetic structure that is found in Saltmarsh Sparrows may result from natal philopatry and breeding-site fidelity, combined with restricted dispersal due to obligate dependence on a patchy habitat, and suggest that fine-scale population structure may be important in some migratory passerines.
Genetic Barcode RFLP Analysis of the Nelson's and Saltmarsh Sparrow Hybrid Zone
A DNA barcoding restriction fragment length polymorphism (RFLP) test is developed and applied to 426 putative Saltmarsh Sparrows sampled from Maine to New York, USA and offers new insights into the extent of hybridization between the two species.
Historical DNA as a tool to address key questions in avian biology and evolution: A review of methods, challenges, applications, and future directions
Using avian systems as a model, a review of DNA extraction protocols, sequencing technologies, and capture methods that have been used to address fundamental questions related to avian conservation and evolution are reviewed.

These findings offer insight into the dynamics of a hybrid zone traversing a unique environmental gradient and provide evidence for a role of ecological divergence in the maintenance of pure species boundaries despite ongoing gene flow.
A positive relationship between ant biodiversity (Hymenoptera: Formicidae) and rate of scavenger-mediated nutrient redistribution along a disturbance gradient in a south- east Asian rain forest
This is the first documented positive relationship between ant species richness and the rate of an ecosystem process, and if these results are applicable at larger spatial scales for a wider range of nutrient sources, loss of ant species could lead to important changes in the way that ecosystems function.
Subspecies delineation amid phenotypic, geographic and genetic discordance in a songbird
Evidence for adaptive variation among subspecies warrants the consideration of evolutionary potential and genetic novelty when identifying conservation units for this group of Nelson's and salt marsh sparrow complex species.
Demographic analysis demonstrates systematic but independent spatial variation in abiotic and biotic stressors across 59 percent of a global species range
The results suggest that stressors on the fecundity of Saltmarsh Sparrow vary systematically across its range, but independently, and that biotic and abiotic stressors were geographically independent, both on a large spatial scale and locally.
