Evolutionary Conflict: Sperm Wars, Phantom Inseminations
نویسندگان
چکیده
A new experimental study has provided the first definitive evidence for conditional punishment of 'cheats' in a sperm-trading simultaneous hermaphrodite: the sea slug Chelidonura hirundinina. This also provides a rare unequivocal example of conditional reciprocity averting a 'tragedy of the commons' in biology.

Hit or Miss: Fertilization Outcomes of Natural Inseminations by Japanese Quail
Variation in fertilization success underlies sexual selection, yet mating does not guarantee fertilization. The relationship between natural inseminations and fertilization success is essential for understanding sexual selection, yet that relationship and its underlying mechanisms are poorly understood in sperm-storing vertebrates such as birds. Here the relationship is analyzed in mating trial...
متن کاملEvolutionary Psychological Foundations of Civil Wars
I propose an evolutionary psychological perspective on wars and suggest that the ultimate cause of intergroup conflict may be the relative availability of reproductive women. Polygyny, which allows some men to monopolize all reproductive opportunities and exclude others, may increase the prevalence of civil wars, but not interstate wars, which did not exist in the ancestral environment. The ana...
متن کاملFrequency of multiple inseminations in field-collected Anopheles gambiae females revealed by DNA analysis of transferred sperm.
We investigated the frequencies of single and multiple matings in field-collected female Anopheles gambiae by conducting microsatellite DNA analyses on the sperm contained within their spermatheca. Amplifcation by a polymerase chain reaction (PCR) at four loci allowed the detection of sperm extracts exhibiting more than two alleles per locus, thereby revealing the occurrence of multiple insemin...

OBJECTIVE To study the efficacy of performing two inseminations per cycle in IUI with husband's sperm compared with one insemination per cycle. DESIGN Meta-analysis. SETTING Randomized and prospective trials comparing two inseminations vs. one insemination per cycle in IUI with husband's sperm, retrieved by MEDLINE and Cochrane Library searches (1966-2001) and a manual search of the abstrac...
متن کاملStorage and survival of turkey spermatozoa in the domestic hen's oviduct.
The percentage of fertilized eggs from chicken hens inseminated with turkey semen is very low (Warren & Scott, 1935; Quinn, Burrows & Byerley, 1937; Asmundsen & Lorenz, 1957; Wisoki & Soller, 1968), but it can be considerably increased by depositing the spermatozoa beyond the utero-vaginal junction (Kempenich-Pinto, Schindler, Bornstein & Baroutchieva, 1970). The question arose whether the inse...
