Ecology and Environmental Protection
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. Molecular analyses were used to assess the freezing effect on the statoblasts, especially analyses of the amount and quality of extracted DNA. Statoblasts were subjected to varying degrees of freezing temperatures and durations to simulate natural and extreme conditions. Preliminary findings suggest that freezing significantly affects statoblast viability and germination potential, with survival rates varying depending on the intensity and duration of freezing.
Furthermore, differential responses among statoblast populations from diverse habitats highlight potential adaptations to local environmental conditions. These results contribute to our understanding of bryozoan life history strategies and their resilience to environmental stressors, providing insights into the ecological dynamics of freshwater ecosystems. Further research is needed to elucidate the mechanisms underlying statoblast responses to freezing and their implications for bryozoan population dynamics in changing environments.
