“…This pollen assemblage represents a proglacial forest-tundra and assigned an age of 14-16 ka. A patterned fen environment at the sites of Wall and Thompson lakes is consistent with the algal palynomorph assemblage containing desmids and other green algal palynomorphs and the presence of the pollen of several aquatic plants (Typha, Myriophyllum, Nymphaea, and Potamogeton; Hall and McCourt, 2015;John and Rindi, 2015).…”

Twenty-four new optically stimulated luminescence (OSL) and radiocarbon ages from sediment cores in nine lakes associated with the Shipshewana and Sturgis moraines in northern Indiana and southern Michigan estimate when recession of the Saginaw Lobe of the Laurentide Ice Sheet was underway in the southern Great Lakes region, USA. Average OSL ages of 23.4 ± 2.2 ka for the Shipshewana Moraine and 19.7 ± 2.2 ka for the Sturgis Moraine are considered minimum limiting deglacial ages for these recessional moraines. The much younger radiocarbon ages are consistent with other regional radiocarbon ages from lakes, and record climate amelioration around ~16.5 cal ka BP. Early recession of the interlobate Saginaw Lobe was well underway by 23.4 ± 2.2 ka, when the adjacent Lake Michigan and Huron-Erie lobes were a few hundred kilometers farther south and near their maximum southerly limits. The results provide the first time constraints when sediment from the Lake Michigan and Huron-Erie lobes began filling the accommodation space left by the Saginaw Lobe. The difference between the oldest radiocarbon and OSL age is 7400 yr for the Shipshewana Moraine and 3400 yr for the Sturgis Moraine.

“…Their thalli can be up to 1 m long, and they form underwater meadows in freshwater ponds and streams. Although the vast majority of the ~700 known species of Charales (Guiry and Guiry ) grow in freshwater (John and Rindi ), there are also examples from brackish water, notably in the upper Baltic Sea (Schubert and Blindow ) and salt‐contaminated lakes in Australia (Burne et al. ).…”

“…Approximately 80% of the >6,000 green algal species (Guiry and Guiry ) are freshwater and ~20% are marine or brackish species (John and Rindi ). Microscopic species are usually found in freshwater and macrophytic taxa in marine waters (John and Rindi ). Multicellular chlorophytes have developed in four lineages, the Palmophyllales (Mamiellophyceae), the Trebouxiophyceae, the Chlorophyceae, and the Ulvophyceae (Leliaert et al.…”

“…These groups are not included in this review. Among the filamentous forms, most occur primarily in freshwater (John and Rindi ), although several freshwater to marine transitions have occurred. One freshwater to seawater transition probably arose in the Chaetopeltidales, a freshwater/terrestrial order that also comprises marine species in the genus Pseudulvella (Sanchez‐Puerta et al.…”

“…The Bolbocoleaceae and the Phaeophilaceae are considered marine (e.g., Hauck , Wynne ), while the Cloniophoraceae are found only in freshwater or brackish environments. Members of the genus Dilabifilum are found mainly in freshwater or terrestrial habitats (John and Rindi ) but also hypersaline environments (Vinogradova and Darienko ). The largest families within the Ulvales (i.e., the Kornmanniaceae, Ulvaceae, and Ulvellaceae) are represented by both freshwater and marine taxa, though they are mainly marine (Wehr and Sheath b).…”

Marine-freshwater and freshwater-marine transitions have been key events in the evolution of life, and most major groups of organisms have independently undergone such events at least once in their history. Here, we first compile an inventory of bidirectional freshwater and marine transitions in multicellular photosynthetic eukaryotes. While green and red algae have mastered multiple transitions in both directions, brown algae have colonized freshwater on a maximum of six known occasions, and angiosperms have made the transition to marine environments only two or three times. Next, we review the early evolutionary events leading to the colonization of current habitats. It is commonly assumed that the conquest of land proceeded in a sequence from marine to freshwater habitats. However, recent evidence suggests that early photosynthetic eukaryotes may have arisen in subaerial or freshwater environments and only later colonized marine environments as hypersaline oceans were diluted to the contemporary level. Although this hypothesis remains speculative, it is important to keep these alternative scenarios in mind when interpreting the current habitat distribution of plants and algae. Finally, we discuss the roles of structural and functional adaptations of the cell wall, reactive oxygen species scavengers, osmoregulation, and reproduction. These are central for acclimatization to freshwater or to marine environments. We observe that successful transitions appear to have occurred more frequently in morphologically simple forms and conclude that, in addition to physiological studies of euryhaline species, comparative studies of closely related species fully adapted to one or the other environment are necessary to better understand the adaptive processes.
