A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.

Although there is much interest in the effects of sperm competition on sexual dimorphism, it is suggested that traditional explanations based on social mating systems are better predictors ofDimorphism in birds.

Sexual selection explains Rensch's rule of allometry for sexual size dimorphism

In 1950, Rensch first described that in groups of related species, sexual size dimorphism is more pronounced in larger species. This widespread and fundamental allometric relationship is now commonly…
Confidence of Paternity and Male Parental Care

The model illustrates that the relationship between male parental care and paternity is more complex than assumed previously and a predicted adjustment ofmale parental care in response to paternity must be examined in relation to the effect of female parental care on offspring recruitment and the effect on alternative activities on male fitness.
Maternal testosterone in tree swallow eggs varies with female aggression

In tree swallows, Tachycineta bicolor, it is found that yolk testosterone was correlated with the aggressive interactions of the female before and during egg laying and did not vary with laying order in tree swallow.
Sexual selection accelerates signal evolution during speciation in birds

It is shown that elevated levels of sexual selection are associated with more rapid phenotypic divergence between related lineages, and that this effect is restricted to male plumage traits proposed to function in mate choice and species recognition.
Sperm competition and the evolution of testes size in birds
- T. Pitcher, P. Dunn, L. A. Whittingham
- Biology, Environmental ScienceJournal of Evolutionary Biology
- 1 May 2005
In analyses of both the raw species data and phylogenetically independent contrasts, monogamous taxa had smaller testes than taxa with multiple social mates, and testes size tended to increase with clutch size, which suggests that sperm depletion may play a role in the evolution oftestes size.
THE EVOLUTION OF SEXUAL SIZE DIMORPHISM IN THE HOUSE FINCH. V. MATERNAL EFFECTS

- 1 February 2003
The compensatory interaction between the onset of incubation and the sex-biased laying order achieved a compromise between maternal and offspring adaptations and contributed to rapid morphological divergence in sexual dimorphism between populations of the house finch breeding at the climatic extremes of the species range.
Quantifying avian sexual dichromatism: a comparison of methods
- Jessica K. Armenta, P. Dunn, L. A. Whittingham
- Biology, Environmental ScienceJournal of Experimental Biology
- 1 August 2008
Using colour data on over 900 species of birds, three methods of calculating sexual dichromatism using spectrophotometer data are compared and it is found that all three methods yielded essentially comparable estimates of dichromeatism for an extensive sample of birds.
