Displaying to females may lower male foraging time and vigilance in a lekking bird
- Psychology, Biology
The costs of display in lekking male Sharp-tailed Grouse (Tympanuchus phasianellus) are investigated to suggest a reduction in on-lek foraging time, and reduced visual attention to the surroundings.
The energetic cost of calling in the variable field cricket, Gryllus lineaticeps
Females of this species prefer higher chirp rates, thus some call types that increase the male's attractiveness to females require more metabolic energy to produce, which increases the metabolic energy required to produce oxygen.
Display activity and foraging costs of a frugivorous lekking bird
- BiologyThe Wilson Journal of Ornithology
A fruit supplementation experiment and recorded male displays in 23 arenas on 5 leks in southeastern Brazil revealed the flight-down was the display most related to fruit consumption (and energy refueling) by males of the White-bearded Manakin.
The costs of female choice in a lekking bird
Analyzing the costs of active female choice in sage grouse, Centrocercus urophasianus, a lekking species in which females make repeated, lengthy visits to leks to assess males before mating concludes that either indirect or direct benefits could provide a plausible solution to the lek paradox.
Energetic costs of size and sexual signalling in a wolf spider
- Environmental ScienceProceedings of the Royal Society of London. Series B: Biological Sciences
The results indicate that sexual signalling in the wolf spider Hygrolycosa rubrofasciata (Ohlert) is highly energetically demanding, which may be the main reason for the honesty of signalling in this species.
Energetic cost of sexual attractiveness: ultrasonic advertisement in wax moths
- PsychologyAnimal Behaviour
The results are consistent with the good genes model of sexual selection, and they do not conflict with other indirect or direct mechanisms of female choice.
Intraspecies variation in avian energy expenditure: correlates and constraints
- Environmental Science, Biology
Intraspecies variation in daily energy expenditure was found to be positively correlated with brood provisioning rates, percentage of time flying and the frequency of non-resting activity, and with body-mass, body-size and several environmental factors.
Using whole-group metabolic rate and behaviour to assess the energetics of courtship in red-sided garter snakes

The energy costs of sexual dimorphism in mole-rats are morphological not behavioural
- Biology, Environmental ScienceProceedings of the Royal Society B: Biological Sciences
This work compared the daily energy expenditure (DEE) and resting metabolic rate (RMR) of males and females of two species of mole-rat and hypothesized that large body size might be indicative of greater digging or fighting capabilities, and hence greater mass-independent DEE values in males of the sexually dimorphic species.
Relationships between Blood Parasites, Mating Success and Phenotypic Cues in Male Sage Grouse Centrocercus urophasianus
Several additional lines of evidence, including numerically low infection intensities, the absence of detectable effects of parasites on hematocrit and erythrocyte production, and the seasonal distribution of parasite incidence suggested that infections were unlikely to impact male courtship display.

The Enzymatic Basis of High Metabolic Rates in Calling Frogs
- Biology, Environmental SciencePhysiological Zoology
The capacity of male spring peeper trunk muscles for aerobic metabolism exceeds considerably the highest values yet reported for ectothermic vertebrate muscle tissue and is comparable to highly oxidative muscles of endotherms.
Oxygen Consumption during Resting, Calling, and Nest Building in the Frog Physalaemus Pustulosus
- BiologyPhysiological Zoology
Because there is a high energy cost associated with reproductive activities in Physalaemus, and presumably in other anurans, any interpretations of aerobic and anaerobic metabolic patterns in frogs and toads should take into account reproductive, as well as predatory and escape, behavior.
Energetics of Free-Ranging Seabirds
Three major areas in the energetics of free-ranging adult seabirds are addressed: basal metabolism, locomotion, and energy budgets.
REPRODUCTIVE BEHAVIOR AND AEROBIC CAPACITIES OF MALE AMERICAN TOADS (BUFO AMERICANUS): IS BEHAVIOR CONSTRAINED BY PHYSIOLOGY?
- Psychology, Biology
The hypothesis that individual differences in calling and searching by males in a chorus of Bufo americanus were correlated with differences in aerobic capacity was not correlated with any behavioral variable, and there was no relationship between behavioral or physiological measurements and male body size.

The Prudent Parent: Energetic Adjustments in Avian Breeding 1)

Energetics of reproduction in birds is reviewed, and observations of parent starlings confronted with manipulated brood size suggest a limit on the time that can be devoted to energetically extravagant flight activity, rather than a shortage of absolute time.
Bat Predation and Sexual Advertisement in a Neotropical Anuran
- BiologyThe American Naturalist
The role of predation in the evolution of the vocal repertoire of the frog Physalaetnus pustulosus is investigated and the hypothesis that male P. pustULostus that produce calls more attractive to females are also more prone to predation by T. cirrhosis is tested.
Standard Operative Temperatures and Thermal Energetics of the Antelope Ground Squirrel Ammospermophilus leucurus
- Environmental SciencePhysiological Zoology
Findings strongly support the interpretation that the thermoregulatory strategy of A. leucurus involves cycles of transient hyperthermia followed by periods of passive heat dissipation underground, which is three to four times the rate of metabolic heat production for active individuals.
Use of non-arbitrary acoustic criteria in mate choice by female gray tree frogs
It is shown that selective phonotaxis by female gray tree frogs depends on non-arbitrary acoustic cues that indicate the male's species and energetic costs of signal production, and some female preferences cannot be explained by differences in signal conspicuousness alone.
