  • 22 February 2007
Operational sex ratio (the ratio of sexually active males to fertilizable females) has a major influence on male competition for mates and male–female interactions. The contributions of male andExpand

Evolution of sperm quality but not quantity in the internally fertilized fish Xiphophorus nigrensis
Abstract Species with alternative reproductive strategies are characterized by discrete differences among males in suites of traits related to competition for fertilizations. Models predict sneakerExpand

Opposing effects of sperm viability and velocity on the outcome of sperm competition
Sperm competition is often envisaged as a raffle where differences in sperm quality "load" the raffle in favor of the male with the higher quality sperm. Sperm quality, however, is a complex trait,Expand

Artificial Microbiome-Selection to Engineer Microbiomes That Confer Salt-Tolerance to Plants
We develop a method to artificially select for rhizosphere microbiomes that confer salt-tolerance to the model grass Brachypodium distachyon. We differentially propagate microbiomes within theExpand

Female fitness declines with increasing female density but not male harassment in the western mosquitofish, Gambusia affinis
Sexual conflict occurs when individuals of one sex express traits that reduce the fitness of individuals of the other sex. In many poeciliid fish, males harass females for copulations, which isExpand

Sexual transmission of beneficial microbes.
Beneficial sexually transmitted infections (STIs) are an understudied phenomenon with important implications for the evolution of cooperation and host reproductive behavior. Challenging theExpand

Biogeography of mutualistic fungi cultivated by leafcutter ants
Leafcutter ants propagate co‐evolving fungi for food. The nearly 50 species of leafcutter ants (Atta, Acromyrmex) range from Argentina to the United States, with the greatest species diversity inExpand

  • 1 March 2014
Genetic analyses of parentage provide crucial information about the prevalence of polyandry and the potential for sexual selection to operate in wild populations. In the swordtail XiphophorusExpand

Tactic-dependent plasticity in ejaculate traits in the swordtail Xiphophorus nigrensis
In species with alternative reproductive tactics, males that sneak copulations often have larger, higher quality ejaculates relative to males that defend females or nest sites. Ejaculate traits can,Expand

Copy number variation in the melanocortin 4 receptor gene and alternative reproductive tactics the swordtail Xiphophorus multilineatus
Alternative reproductive tactics are powerful examples of how variation in genetics and physiology among individuals can lead to striking diversity in phenotype. In the swordtails (genusExpand
