Since Darwin's conception of sexual selection theory, scientists have struggled to identify the
evolutionary forces underlying the pervasive differences between male and female …

Long-chain polyunsaturated fatty acids (LC-PUFA) are major components of complex lipid
molecules and are also involved in numerous critical biological processes. Studies …

Far more species of organisms are found in the tropics than in temperate and polar regions,
but the evolutionary and ecological causes of this pattern remain controversial 1, 2. Tropical …

Our understanding of the diversity and evolution of vertebrate RNA viruses is largely limited
to those found in mammalian and avian hosts and associated with overt disease. Here …

Body size determines total reproductive-energy output. Most theories assume reproductive
output is a fixed proportion of size, with respect to mass, but formal macroecological tests are …

Background Fish classifications, as those of most other taxonomic groups, are being
transformed drastically as new molecular phylogenies provide support for natural groups …

Our understanding of phylogenetic relationships among bony fishes has been transformed
by analysis of a small number of genes, but uncertainty remains around critical nodes …

Shifts in phenology are already resulting in disruptions to the timing of migration and
breeding, and asynchronies between interacting species,,,–. Recent syntheses have …

Sturgeons seem to be frozen in time. The archaic characteristics of this ancient fish lineage
place it in a key phylogenetic position at the base of the~ 30,000 modern teleost fish …

To connect human biology to fish biomedical models, we sequenced the genome of spotted
gar (Lepisosteus oculatus), whose lineage diverged from teleosts before teleost genome …
