Influence of roadways on patterns of mortality and flight behavior of adult dragonflies near wetland areas
The relatively low population size and long adult lifespan of dragonflies (Odonata, Anisoptera) makes them one of the few non-vertebrate groups likely to be impacted by direct roadway mortality. WeExpand

Do male crickets strategically adjust the number and viability of their sperm under sperm competition?
Sperm competition theory predicts that males should strategically adjust sperm ejaculate expenditure according to the number of competing ejaculates, because sperm production is costly. That is,Expand

Direct costs and benefits of multiple mating: Are high female mating rates due to ejaculate replenishment?
Females often mate more than is necessary to ensure reproductive success even when they incur significant costs from doing so. Direct benefits are hypothesized to be the driving force of high femaleExpand

Mating for male-derived prostaglandin: a functional explanation for the increased fecundity of mated female crickets?
ABSTRACT Direct benefits are considered to be the driving force of high female mating rates, yet species in which females do not receive material resources from males still experience increasedExpand

Females gain survival benefits from immune‐boosting ejaculates
Females in many animal taxa incur significant costs from mating in the form of injury or infection, which can drastically reduce survival. Therefore, immune function during reproduction can beExpand

Evaluating indices of body condition in two cricket species
Body mass components (dry mass, lean dry mass, water mass, fat mass) in each sex correlate strongly with body mass and pronotum length in Gryllus texensis and Acheta domesticus. Ordinary leastExpand

Gender differences in survival and antipredatory behavior in stalk-eyed flies
Exaggerated eye span of stalk-eyed flies is a classic example of the evolution of an extravagant male ornament resulting from sexual selection. Increased male eye span may entail costs associatedExpand

Size matters, but so does shape: quantifying complex shape changes in a sexually selected trait in stalk‐eyed flies (Diptera: Diopsidae)
The elaborate morphologies of sexually selected ornaments are ubiquitous across the animal kingdom. In studies investigating these traits, ornament size is frequently the focus, and empiricalExpand

The Fat-Dachsous signaling pathway regulates growth of horns in Trypoxylus dichotomus, but does not affect horn allometry.
Males of the Asian rhinoceros beetle, Trypoxylus dichotomus, possess exaggerated head and thoracic horns that scale dramatically out of proportion to body size. While studies of insulin signalingExpand

Sequential Analysis Reveals Behavioral Differences Underlying Female-Biased Predation Risk in Stalk-Eyed Flies
Stalk-eyed flies are classic models of how sexual selection can drive morphological and behavioral elaboration. Exaggerated ornaments born by stalk-eyed flies could impose locomotor costs andExpand
