Host and antibiotic jointly select for greater virulence in Staphylococcus aureus Open
Widespread antibiotic usage has resulted in the rapid evolution of drug-resistant bacterial pathogens and poses significant threats to public health. Resolving how pathogens respond to antibiotics under different contexts is critical for u…
Host and antibiotic jointly select for greater virulence in Staphylococcus aureus Open
Widespread antibiotic usage has resulted in the rapid evolution of drug-resistant bacterial pathogens and poses significant threats to public health. Resolving how pathogens respond to antibiotics under different contexts is critical for u…
Variation in self-compatibility among genotypes and across ontogeny in a self-fertilizing vertebrate, <i>Kryptolebias marmoratus</i> Open
Mixed-mating strategies can maximize the benefits and limit the costs of both self-fertilization and outcrossing. In addition to ecological conditions and population dynamics, the economics of mixed mating are determined by individual self…
The Adoption Potential of Extended Lactation as a Strategy to Reduce Excess Calf Numbers in Dairy Farming Open
Dairy production relies predominantly on a few, selectively bred, high-yielding dairy breeds, resulting in a surplus of low-value male offspring. This situation leads to a conflict between a growing demand for milk and low appreciation for…
Host and antibiotic jointly select for greater virulence in <i>Staphylococcus aureus</i> Open
Widespread antibiotic usage has resulted in the rapid evolution of drug-resistant bacterial pathogens and poses significant threats to public health. Resolving how pathogens respond to antibiotics under different contexts is critical for u…
Outcrossing in <i>Caenorhabditis elegans</i> increases in response to food limitation Open
Theory predicts that organisms should diversify their offspring when faced with a stressful environment. This prediction has received empirical support across diverse groups of organisms and stressors. For example, when encountered by Caen…
Outcrossing increases resistance against coevolving parasites Open
Despite substantial costs, biparental sex is the dominant mode of reproduction across plant and animal taxa. The Red Queen hypothesis (RQH) posits that coevolutionary interactions with parasites can favor biparental sex in hosts, despite t…

Male mate choice unresolved in the mangrove rivulus Open
Mate choice has the potential to drive phenotypic evolution because it can determine traits that increase an individual’s likelihood to reproduce (courtship behaviors, elaborate ornamentation). These traits, however, can also be detrimenta…
Outbreeding depression as a selective force on mixed mating in the mangrove rivulus fish, <i>Kryptolebias marmoratus</i> Open
Mixed mating, a reproduction strategy utilized by many plants and invertebrates, optimizes the cost to benefit ratio of a labile mating system. One type of mixed mating includes outcrossing with conspecifics and self-fertilizing one’s own …
Relationships between external sexually dimorphic characteristics and internal gonadal morphology in a sex‐changing fish Open
The mangrove rivulus fish ( Kryptolebias marmoratus ) is an emerging model for research in the biological sciences. The species is androdioecious, with populations consisting predominantly of self‐fertilizing hermaphrodites and a low abund…
