El apareamiento entre hermanos en una avispa de caza: ¿la endogamia adaptativa?
Science (New York, N.Y.)
|September 28, 1979
Resumen
Las avispas masculinas de Euodynerus foraminatus compiten por el territorio y se aparean con sus hermanas al emerger. A pesar de ser fuertes voladores, estas avispas comunes pueden preferir la endogamia incluso cuando la endogamia es una opción.
Área de la Ciencia:
- Ecología del comportamiento Ecología del comportamiento.
- Comportamiento del insecto Comportamiento del insecto
- Biología evolutiva Biología evolutiva.
Sus antecedentes:
- Euodynerus foraminatus, una especie de avispa común, exhibe comportamientos únicos de apareamiento.
- En muchas especies, la endogamia ocurre debido a la dispersión limitada o la disponibilidad de pareja.
Objetivo del estudio:
- Para investigar el comportamiento de apareamiento de Euodynerus foraminatus.
- Explorar el potencial de preferencia entre hermanos en el apareamiento a pesar de las fuertes capacidades de vuelo.
Principales métodos:
- Estudios observacionales de emergencia de avispas y apareamiento cerca de nidos natales.
- Análisis conductuales para evaluar la elección de pareja y los patrones de dispersión.
Principales resultados:
- Los machos compiten por microterritorios alrededor del nido natal.
- El macho ganador insemina a sus hermanas emergentes.
- Tanto las avispas macho como las hembras son fuertes voladores, lo que sugiere que la dispersión es posible.
Conclusiones:
- Euodynerus foraminatus se involucra en el apareamiento entre hermanos.
- La fuerte capacidad de vuelo plantea preguntas sobre las presiones selectivas que favorecen la endogamia en esta especie.
- Se necesita más investigación para determinar si la preferencia por los hermanos persiste incluso cuando existen oportunidades de reproducción externa.

01:20Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
00:57Inclusive Fitness
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.
01:17Understanding Species and Reproductive Barriers
A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...
02:29Hybrid Zones
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:06Natural Selection and Mating Preferences
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
