Abstract
Pleistocen ili ''ledeno doba'' kao razdoblje specifično je po cikličnim izmjenama glacijalnih i interglacijalnih perioda. Živi svijet se, osim stalnih promjena klimatskih uvjeta, susreće i sa mnogim drugim izazovima (npr. geološki procesi kao što su orogeneze, okršavanje i sl.). Tokom glacijalnog perioda, na pojedinim mjestima u Europi kao što su Pirenejski, Balkanski i Apeninski poluotok, nastaju utočišta ili refugiji, mjesta sa blažom klimom u kojoj organizmi imaju šansu za preživjeti. Kralježnjaci i beskralježnaci drukčije preživljavaju ovo razdoblje. Dok kopneni kralježnjaci imaju relativno dobru sposobnost migracije, vodene vrste beskralježnaka su ograničene na tokove rijeka. Tokom glacijala, slatkovodne populacije beskralježnjaka se pomoću tokova rijeka djelomično povlače u refugijske prostore te tamo opstaju, a dio njih preživljava lokalno uslijed vertikalnih migracija. Kasnije, u interglacijalu, ponovno naseljavaju slobodne prostore ili ostaju izolirane, a ovaj se proces ponavlja u ciklusima. Dugotrajnom prostornom izolacijom populacije divergiraju, te nastaju nove linije i vrste.
Abstract (english)
Pleistocene or ''ice age'' as a period is specific by its cyclic changes in glacial and interglacial periods. Biological life, besides changes in climatic conditions, is facing various challenges (e.g. Orogenesis, karstification, etc.). Some regions in Southern Europe, like the Iberian Peninsula, the Balkans and the Apennine Peninsula, serve as refugial areas for plants and animals during the glacials. The refugium has a slightly warmer climate in which organisms have a chance of survival during the glacial period. Vertebrates and invertebrates have different ways of surviving these periods. While terrestrial vertebrates have relatively high dispersal abilities, the freshwater invertebrates are limited mainly to vertical migration in running waters. During glacials, freshwater invertebrate populations are retrieving in refugial areas where they survive, some even survive locally by vertical migration. During the interglacials, freshwater species are recolonizing newly available habitats or remain isolated locally. This process repeats itself for a few cycles. Through long-term isolation, populations evolve and diverge from their original lineage resulting in distinct lineages and new species.
