TL;DR: It is argued that future research must consider sperm and seminal fluid components of the ejaculate as a functional unity, and that research at the genomic level will identify the genes that ultimately control male fertility.

TL;DR: It is shown that sperm competition selects for increases in the number, size, and longevity of spermatozoa in the ejaculate of a male, and, contrary to expectations from theory, there is no evidence of trade-offs among sperm traits in an interspecific analysis.

TL;DR: It is argued that information about sperm evolution gained from non-human animals has enormous potential to further the understanding of the factors that impact human fertility.

TL;DR: The fact that DOC from freshwater sources provides protection against Cu toxicity in seawater suggests that extrapolation from freshwater toxicity testing may be possible for saltwater criteria development, including development of a saltwater Biotic Ligand Model for prediction of Cu toxicity.

TL;DR: It is shown why consideration of additional life-history, ecological, and mating-system variables is crucial for the interpretation of associations between secondary sexual traits and ejaculate production, and provides evidence that interactions between pre- and post-mating sexual selection can underlie broad patterns of diversification in male weapons and ornaments.
