When conditions deteriorate, freshwater cladocerans from the genus Daphnia switch to production of diapausing eggs encased in chitinous shells called ephippia. Ephippia may serve for temporal escape and recolonisation of the habitat or for geographical dispersal and colonization of other habitats. While dormancy and dispersal of ephippia have been well studied, initial factors determining the fate of the ephippia have remained unknown. We first consider the fate of an ephippium that sinks to the bottom of the water body, where it enriches the egg bank present in the sediments. We then discuss the potential and evidence for dispersal of ephippia, which is probably facilitated by their flotation on the water surface. Finally, we concentrate on the moment of the release of the ephippium showing a likely mechanism that determines its further fate - temporal or spatial dispersal - and we demonstrate it to be accomplished through maternal behaviour.

Celem pracy była ocena wpływu odmiany barwnej i wieku na niektóre wskaźniki użytkowości rozrodczej norek. Analizowano: wielkość miotu, liczbę żywo urodzonych i odchowanych młodych z jednego miotu, śmiertelność młodych w okresie odchowu przy matkach, długość ciąży i diapauzy. Odmiana barwna oraz wiek miały statystyczny wpływ na wszystkie omawiane wskaźniki rozrodu norek. Wielkość miotu, liczba żywo urodzonych młodych oraz liczba odchowanych młodych z jednego miotu były większe u samic w pierwszym roku użytkowania rozrodczego niż u samic w drugim i trzecim roku. Śmiertelność młodych norek w okresie odchowu przy matkach była najmniejsza w pierwszym roku użytkowania rozrodczego u wszystkich odmian. Zarówno diapauza, jak i całkowita długość ciąży były krótsze w drugim roku użytkowania rozrodczego w porównaniu z pierwszym rokiem. Odmiana barwna standard czarny charakteryzowała się najlepszymi wynikami rozrodu. Natomiast samice odmiany standard czarny short NAP charakteryzowały się najkrótszymi okresami diapauzy i długości ciąży.

The aim of this study was to evaluate the effects of colour variety and age on some reproductive performance parameters in mink.We analysed litter sizes, live-born rate and weaned per litter, mortality during maternal nursing, gestation length, and diapause duration. The colour variety and age significantly affected all the discussed reproduction parameters of mink. Liter size, live-born rate, and weaned number pr litter were higher in females in the first year of breeding, as compared to those at the second and third years.Mortality during maternal nursing was lowest in the first year in all the studied varieties. Both diapause and total gestation length were shorter in the second year of breeding compared to the first year. The Black Standard variety was characterised by the best reproduction parameters. On the other hand, Black Standard Short NAP had the shortest diapause and gestation periods.
