Charged Amino Acid Frequencies of Proteins over Macroevolutionary Time Scale

Charged amino acids (AAs) are targets for selective forces in protein evolution. To fully explore the trend of charged AA frequencies evolution in macroevolutionary process from prokaryotes to eukaryotes, we extend the analysis of five charged AAs separately and total basic and acidic AAs in protein sequences of 158 prokaryotic and 63 eukaryotic predicted proteomes and 456 clusters of orthologo...

Onshore-offshore gradient in metacommunity turnover emerges only over macroevolutionary time-scales.

Invertebrate lineages tend to originate and become extinct at a higher rate in onshore than in offshore habitats over long temporal durations (more than 10 Myr), but it remains unclear whether this pattern scales down to durations of stages (less than 5 Myr) or even sequences (less than 0.5 Myr). We assess whether onshore-offshore gradients in long-term turnover between the tropical Eocene and ...

Transmembrane Protein Oxygen Content and Compartmentalization of Cells

Recently, there was a report that explored the oxygen content of transmembrane proteins over macroevolutionary time scales where the authors observed a correlation between the geological time of appearance of compartmentalized cells with atmospheric oxygen concentration. The authors predicted, characterized and correlated the differences in the structure and composition of transmembrane protein...

Water Balance Modelling Over Variable Time Scales

Partitioning of rainfall into evapotranspiration and runoff is controlled by climate and catchment characteristics. The degree of control exerted by these factors varies with the spatial and temporal scales of processes being modelled. Understanding individual hydrological processes and their relationships with climatic and catchment characteristics is an important step in predicting catchment ...

Sustaining fisheries yields over evolutionary time scales.

Fishery management plans ignore the potential for evolutionary change in harvestable biomass. We subjected populations of an exploited fish (Menidia menidia) to large, small, or random size-selective harvest of adults over four generations. Harvested biomass evolved rapidly in directions counter to the size-dependent force of fishing mortality. Large-harvested populations initially produced the...
