Orientación en la migración animal
Animal migration relies on genetic, terrestrial, and celestial information to determine destinations and routes. Species use internal biological clocks and compasses, such as magnetic, solar, and stellar cues, to navigate long distances. The article explains how different organisms integrate these cues to correct their movements.
- ▪Genetic inheritance guides the preferred migration directions of birds, and crossbreeding can produce intermediate routes.
- ▪Simple animals like crustaceans and ants use body orientation and central nervous system cues to estimate speed, time, and distance.
- ▪Complex animals possess biological clocks and magnetic compasses that allow them to determine latitude from star positions or magnetic inclination.
- ▪Solar and stellar references, including sun position and star patterns, are synchronized with internal rhythms to aid navigation during day and night.

Orientación en la migración animal ¿Cómo conocen su destino... y la trayectoria a seguir? Regala esta noticia Añádenos en Google Manuel Tello 21/02/2021 Actualizado a las 15:48h. Normalmente, en otoño y primavera millones de animales realizan largos viajes, de cientos o miles de kilómetros según la especie. Estos viajes plantean muchas preguntas: ¿Cómo conocen su destino? ¿Y la trayectoria? Para contestarlas se debe tener en cuenta que los animales utilizan tres tipos de información: genética, terrestre y celeste. Y poseen brújulas y relojes biológicos activados por sensores internos. En primer lugar tenemos la genética. Fijémonos, como ejemplo, en aves que migran desde Europa a un destino definido pero, en general, no único. Por ejemplo, hacia el sur, sureste y suroeste.
