... glacial stage would appear to preclude large parts of the island acting as biological refugia during the LGM. However, the present evidence on the extent and nature of the ice cap does not exclude the possibility that there were isolated ice-free areas, in both the marine and terrestrial environment...

... (Portnoy et al. 2014 ). Other Pleistocene refugia for thermophilic dinoflagellates have been described in the Pacific Ocean, notably the Indo-Pacific warm pool and the recent discovery of the living fossil dinoflagellate Dapsilidinium pastielsii (Mertens et al. 2014 ). Cysts of M. choanophorum...

..., acting as a stable substrate, food source, and oxygen supply. Shallow-water microbial communities have been interpreted as refugia, but this deeper site may have been critical to organisms with temperature sensitivities. Published paleotemperature calculations suggest sublethal surface temperatures of 34...

During the MIS 3 interstade, subalpine forest existed at low elevations on Graham Island, providing environments suitable for the development of genetically distinct bird and mammal populations that survived in lowland refugia during the Fraser Glaciation. 24 2 2015 8...

After each glacial event, coal forests reassembled with largely the same species composition. This remarkable stasis implies that coal-forest refugia existed across...

... uniform front west to the edge of the continental shelf. However, the distribution of plants and animals in the region has led many biologists to suggest that there may have been ice-free areas that served as refugia during the late Wisconsin.

Associated with these extinctions, we found evidence of geographic range restriction, but not range shifts, in corbulid genera, indicating that the geologic development of environmental refugia...
