In birds, observed adult sex ratios often are biased towards males. This bias could arise due to differences between sexes in dispersal or in catchability, but a preferred explanation has been sex differences in survival. However, most studies investigated apparent...

Background: Increasingly interests in the potential use of insect symbionts Wolbachia to control populations of pest species were focused on many vector pest species and agricultural insects. However, few pieces of researches were reported in stored product insects....

Sequences and structural attributes of mitochondrial genomes have played a key role in the clarification of relationships among Cnidaria, a key phylum of early-diverging animals. Among the major lineages of Cnidaria, Ceriantharia ("tube anemones") remains one of...

Using a large, consistent set of loci shared by descent (orthologous) to study relationships among taxa would revolutionize among-lineage comparisons of divergence and speciation processes. Ultraconserved elements (UCEs), highly conserved regions of the genome,...

Populations of passively dispersed organisms in continental aquatic habitats typically show high levels of neutral genetic differentiation, despite their high dispersal capabilities. Several evolutionary factors, including founder events and local adaptation, and...

The study of crop evolution has focused primarily on the process of initial domestication. Post-domestication adaptation during the expansion of crops from their centers of origin has received considerably less attention. Recent research has revealed that, in at...

Synopsis: Tyrannosaurid dinosaurs had larger than predicted preserved leg muscle attachments and low rotational inertia relative to their body mass, indicating that they could turn more quickly than other large theropods. Methods: To compare turning capability...

Background: The ancestral dinoflagellate most likely established a peridinin-containing plastid, which has been inherited to the extant photosynthetic descendants. However, kareniacean dinoflagellates and Lepidodinium species were known to bear “non-canonical”...

Phenotypic plasticity is the ability of a genotype to produce different phenotypes depending on the environment. It has an influence on the adaptive potential to environmental change and the capability to adapt locally. Adaptation to environmental change happens...

The Lake Victoria drainage basin (LVD) in Kenya is home to ten nominal species of small barbs (‘Barbus’) and one of large barbs (Labeobarbus altianalis). A recent molecular study genetically characterized small barbs in this region and found evidence of introgression...
