Statoblasts are dormant, asexual propagules critical for the survival and dispersal of bryozoans, such as Pectinatella magnifica. Understanding the resilience of statoblasts to environmental stresses is crucial for predicting the response of bryozoan populations to changing conditions. This study investigates the effect of freezing on the viability of statoblasts from P. magnifica. Statoblasts were collected from Pectinatella magnifica colonies in the Protected Landscape area and Biospheric Reservation Trebonsko. ...
