Theodoxus fluviatilis is a common gastropod in many karstic springs in central Portugal. We investigated the possible reasons for the near-total restriction of this species to these springs. We first determined the spatial distribution of the species within a spring (Anços) and related the densities at sampling-patch scales to selected physical and chemical variables. [...]
Theodoxus fluviatilis es un gasterópodo común en muchas de los manantiales kársticos del centro de Portugal. La pregunta a la que intentamos responder es ¿por qué la especie está prácticamente restricta a los manantiales? Para ello determinamos primero la distribución espacial de T. [...]
