Resumen


Amblyocarenum walckenaeri (Lucas, 1846) (Araneae: Mygalomorphae: Nemesiidae) se encuentra en varias zonas urbanas de La Safor (Valencia, España). Aquí, presentamos un método que podría exponer el efecto perturbador de la rápida expansión urbana en poblaciones de arañas tramperas: contando las clases de edades de una población como indicador de su viabilidad. Nuestros resultados muestran que la mayoría de las poblaciones urbanas muestreadas no presenta crías. Esto sugiere que Amblyocarenum existe en dichas zonas urbanas como remanentes; poblaciones envejecidas que presentan dificultad a la hora de reclutar nuevas generaciones de ejemplares, tornándose inviables.
