- Sperm Competition and Its Evolutionary Consequences in the Insects
Written by a top researcher in the field, this comprehensive, up-to-date review of the evolutionary causes and consequences of sperm competition in the insects will prove an invaluable reference for students and established researchers in behavioral ecology and evolutionary biology
- Sperm Competition and Its Evolutionary Consequences in the Insects on JSTOR
At the time of his review, Parker (1970e) presented evidence of multiple paternity, and thus the potential for sexual selection via sperm competition, in sixteen species of insect from just five orders
- SPERM COMPETITION AND ITS EVOLUTIONARY CONSEQUENCES IN THE INSECTS . . .
Thus a series of behavioural, followed by anatomical and physiological steps, may be G A PARKER envisaged as intermediaries between a simple shedding of gametes into the sea and the present internal fertilization found in many marine species
- Sperm Competition and Its Evolutionary Consequences in the Insects . . .
In his seminal review, “Sperm competition and its evolutionary consequences in the insects,” Geoff Parker (1970) was the first to outline the broad implications that the temporal overlap of competing ejaculates within the female reproductive tract holds for an organism’s reproductive traits
- Insect Sperm Competition - SpringerLink
Geoff Parker’s 1970 ’s studies of yellow dung flies (Scathophaga stercoraria) led him to postulate that: …copulation with internal fertilization may have arisen by a selective advantage conferred upon males able to eject sperm nearer to the ova than did their fellow males Parker was far ahead of the curve
- Sperm Competition And Its Evolutionary Consequences In The Insects
Since the 1970s, this area of research has seen exponential growth, and biologists now recognize sperm competition as an evolutionary force that drives such adaptations as mate guarding,
- Sperm Competition and Its Evolutionary Consequences in the Insects
This book analyzes and extends thirty years of theoretical and empirical work on insect sperm competition It considers both male and female interests in sperm utilization and the sexual conflict that can arise when these differ It covers the mechanics of sperm transfer and utilization, morphology, physiology, and behavior
