Genomics in the ecological arena.
This meeting report presents the cutting-edge research that is developing around the waterflea Daphnia, an emerging model system in environmental genomics. Daphnia has been a model species in ecology, toxicology and evolution for many years and is supported by a large community of ecologists, evolutionary biologists and ecotoxicologists. Thanks to new advances in genomics and transciptomics and...
متن کاملEcological genomics in full colour.
Colour patterns in animals have long offered an opportunity to observe adaptive traits in natural populations. Colour plays myriad roles in interactions within and among species, from reproductive signalling to predator avoidance, leading to multiple targets of natural and sexual selection and opportunities for diversification. Understanding the genetic and developmental underpinnings of variat...
متن کاملEcological Genomics of Model Eukaryotes1
“It is of basic importance to understand the hereditary mechanisms that function in the perpetuation of the existing natural races and species and in the evolution of new ones, but investigations in this field are difficult and have largely been neglected. The commonly used laboratory organisms are inadequate to resolve differences that characterize natural biological entities found in the wild”
متن کاملEcological genomics of marine Roseobacters.
Bacterioplankton of the marine Roseobacter clade have genomes that reflect a dynamic environment and diverse interactions with marine plankton. Comparative genome sequence analysis of three cultured representatives suggests that cellular requirements for nitrogen are largely provided by regenerated ammonium and organic compounds (polyamines, allophanate, and urea), while typical sources of carb...
متن کاملEvolutionary genomics of ecological specialization.
We used a combination of genomic techniques to monitor chromosomal evolution across hundreds of generations as Escherichia coli adapted to growth-limiting concentrations of either lactulose, methyl-galactoside, or a 72:28 mixture of the two. DNA microarrays identified 8 unique duplications and 16 unique deletions among 42 evolvants from 23 chemostat experiments. Each mutation was confirmed by s...
