Background Maternal gene products supplied to the egg during oogenesis drive the earliest events of development in all metazoans. After the initial stages of embryogenesis, maternal transcripts are degraded as zygotic transcription is activated; this is ...

The role of plants in the formation of species-specific features in grass flies (Diptera, Chloropidae, Meromyza) [PDF]
In the current manuscript, we present the results of comparative analysis of seven species of Meromyza flies in the “variegata” cluster and of the evolutionary close species M. inornata, based the following criteria: 1) 14 external key features; 2) shape

Toward understanding the origin and evolution of cellular organisms
In this era of high‐throughput biology, bioinformatics has become a major discipline for making sense out of large‐scale datasets. Bioinformatics is usually considered as a practical field developing databases and software tools for supporting other ...

On nilpotent evolution algebras [PDF]
The type and several invariant subspaces related to the upper annihilating series of finite-dimensional nilpotent evolution algebras are introduced. These invariants can be easily computed from any natural basis.

Threespine Stickleback in Lake Constance: The Ecology and Genomic Substrate of a Recent Invasion
Invasive species can be powerful models for studying contemporary evolution in natural environments. As invading organisms often encounter new habitats during colonization, they will experience novel selection pressures.

Ancient hybridization fuels rapid cichlid fish adaptive radiations
Cichlids underwent a rapid diversification in the Lake Victoria region, expanding to more than 700 species within 150,000 years. Here, Meier and colleagues show that an ancient hybridization between two divergent cichlid lineages generated high genetic ...
