The mismeasure of animal contests
Abstract Contests between rivals placing similar value on the resource at stake are commonly won by the rival having greater ‘resource holding potential’ (RHP). Mutual assessment of RHP differenceExpand

Diet and size influence sexual advertisement and copulatory success of males in Mediterranean fruit fly leks
1. The objective of the work reported here was to test the hypothesis that in insects that invest considerable energy in sexual displays and courtship, foraging successfully for food affects theirExpand

Potential for pre‐release diet supplements to increase the sexual performance and longevity of male Queensland fruit flies
1 Recent studies have shown that continuous access to a protein source (yeast hydrolysate) can greatly enhance the sexual performance of male Queensland fruit flies (Bactrocera tryoni; ‘Q‐flies’).Expand

Postcopulatory sexual selection in Mediterranean fruit flies: advantages for large and protein-fed males
Previous laboratory studies of Mediterranean fruit flies, Ceratitis capitata (medflies), have identified large size and protein feeding as positive influences on the ability of males to secureExpand

Initiation and resolution of jumping spider contests: roles for size, proximity, and early detection of rivals
Abstract. Animals are commonly expected to assess each other during contests in order to economically identify relative status. Escalated or long contests are expected to arise mainly when rivalsExpand

Optimizing Irradiation Dose for Sterility Induction and Quality of Bactrocera tryoni
ABSTRACT The current study is an important step toward calibrating, validating, and improving irradiation methods used for Bactrocera tryoni (Froggatt) sterile insect technique (SIT). We usedExpand

Multimodal communication and mate choice in wolf spiders: female response to multimodal versus unimodal signals
Male wolf spiders (Lycosidae) in the genus Schizocosa vary in use of seismic and visual components of courtship display, ranging from unimodal (seismic only) to multimodal (seismic and visual).Expand

BREAKFAST OF CHAMPIONS OR KISS OF DEATH? SURVIVAL AND SEXUAL PERFORMANCE OF PROTEIN-FED, STERILE MEDITERRANEAN FRUIT FLIES (DIPTERA: TEPHRITIDAE)
Abstract The sterile insect technique (SIT) is increasingly being used around the world to control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), the Mediterranean fruit fly as part of anExpand

Large body size for winning and large swords for winning quickly in swordtail males, Xiphophorus helleri
Contestants can either assess their own resource-holding potential relative to their opponent (mutual assessment) or rely solely on the assessment of their own fighting ability (self-assessment). ToExpand

Protein:carbohydrate ratios explain life span patterns found in Queensland fruit fly on diets varying in yeast:sugar ratios
Dietary restriction extends life span across a vast diversity of taxa, but significant challenges remain in elucidating the underlying mechanisms. Distinguishing between caloric and nutrient effectsExpand
