Los lagartos nativos aprendieron a evitar los sapos tóxicos por las ranas liberadas
Science (New York, N.Y.)
|April 18, 2024
Resumen
La introducción de sapos jóvenes para monitorear lagartos preparó sus sistemas inmunológicos. Esta exposición temprana mejoró significativamente las tasas de supervivencia de los lagartos cuando los sapos adultos invadieron más tarde.
Área de la Ciencia:
- Ecología
- Toxicología
- El comportamiento de los animales
Sus antecedentes:
- Los sapos de caña (Rhinella marina) son una especie invasora en Australia, que representa una amenaza significativa para la vida silvestre nativa.
- Lagartijas monitoreadoras (Varanus spp.) son particularmente vulnerables a las toxinas del sapo de caña debido a su naturaleza depredadora y a la falta de exposición previa.
- Los intentos anteriores para mitigar las invasiones de sapos se han centrado en el control de la población y el manejo del hábitat con un éxito limitado.

02:39Predator-Prey Interactions
16.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

02:29Hybrid Zones
17.0K
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.

01:21Frequency-dependent Selection
22.0K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.
