摘要：Wartykule przedstawiono syntezę dotychczasowego stanu wiedzy o rozwoju jezior przybrzeżnych Niziny Gardzieńsko-Łebskiej i środkowego wybrzeża Bałtyku, bazującą na wynikach badań malakologicznych. Analizy zespołów mięczakówz osadów limnicznych i morskich pozwoliły na wyróżnienie czterech faz rozwojowych jezior: wczesnoholoceńskiejfazy limniczno-bagiennej (trwającej od późnego glacjału do około 7500 lat 14C BP), fazy lagunowej (około 7500–6600 lat 14CBP), fazy przejściowej, słonawowodno-limnicznej (6600–4000 lat 14C BP) oraz fazy jeziornej (młodszej od 4000 lat 14C BP).Wartykule wykazano, iż sukcesja malakofauny jest odzwierciedleniem regionalnych przemian środowiska, zarejestrowanychpodobnymi zmianami zespołów fauny na całym wybrzeżu południowego Bałtyku.
其他摘要：The papers presents the synthesis of the current understanding of the evolution of coastal lakes in theGardno-Łeba Lowland. Particular emphasis has been placed upon the influence of pre-Holocene surface topography onlake basin evolution and water level changes caused by the transgression of southern Baltic. Malacological analysis revealsfour phases in lake environmental history: limnic-swampy phase, lagoon phase, transitional brackish-limnic phase, andlimnic phase.The oldest, early Holocene limnic-swampy phase in the Gardno-Łeba Lowland area is represented by Preboreal and Borealassemblages with freshwater fauna, described as Planorbis phase. It is characterized by rich assemblages, in terms of bothnumber of individuals and species, composed of members of Planorbis, accompanied by Bithynia tentaculata, Valvatapiscinalis and Pisidium. The lagoon-marine phase, described as Scrobicularia phase (7500–6000 BP), is defined by a homogeneousassemblage of malacofauna, consisting entirely of brackish and marine species, such as Hydrobia ulvae, H. ventrosa,Cerastoderma glaucum, Macoma baltica, Mytilus edulis and indicative Lusitanian and Lower Boreal species for theMesoholocene of the southern Baltic, including Scrobicularia plana, Rissoa membranaea, R. inconspicua, Parvicardiumexiguum and Mysella bidentata. The transitional brackish-limnic phase Cardium (6600–4000 BP) is correlated with lateLittorina transgressive phases. It is dominated by Cardium glaucum, with minor percentage of Hydrobia ventrosa, Mytilusedulis, and sporadic freshwater species. The limnic Lymnaea phase corresponds with the post-Littorina period (4000BP–1900 AD). The onset of this phase is marked by an assemblage with dominating Theodoxus fluviatilis, the optimum – byLymnea peregra assemblages, whereas frequent Bithynia tentaculata indicate the end of the phase. The youngest Potamopyrgusphase includes recent lake sediments from the last 100 years and is marked by the first appearance of a new molluscspecies in the coastal zone of the Baltic – Potamopyrgus antipodarium.The malacofauna succession identified in the coastal lakes in the Gardno-Łeba Lowland reflects regional environmental change, recorded by similar faunal assemblages throughout the southern coast of the Baltic.
