A goal of phylogeography is to relate patterns of genetic differentiation to potential historical geographic isolating events. Quaternary glaciations, particularly the one culminating in the Last Glacial Maximum approximately 21 ka (thousands of years ago), greatly affected the distributions and population sizes of temperate marine species as their ranges retreated southward to escape ice sheets. Traditional genetic models of glacial refugia and routes of recolonization include these… 
Comparative Phylogeography of Antarctic Seaweeds: Genetic Consequences of Historical Climatic Variations
In the Southern Ocean, rapid climatic fluctuations during the Quaternary are thought to have induced range contractions and bottlenecks, which drastically impacted marine communities. For
Deep reefs are climatic refugia for genetic diversity of marine forests
TLDR
The global distribution of gene pools of temperate marine forests is explained by past range shifts that structured both latitudinal glacial refugia and depthRefugia during warmer periods, allowing persistence and retaining some of the largest genetic diversity pools of the species' distribution.
Genetic signature of Last Glacial Maximum regional refugia in a circum-Antarctic sea spider
The evolutionary history of Antarctic organisms is becoming increasingly important to understand and manage population trajectories under rapid environmental change. The Antarctic sea spider Nymphon
Glacial History of the North Atlantic Marine Snail, Littorina saxatilis, Inferred from Distribution of Mitochondrial DNA Lineages
TLDR
Examination of phylogeographic patterns of the species' populations in the North Atlantic and one remote Mediterranean population using sequence variation in a fragment of the mitochondrial cytochrome b gene found that, as opposed to many other rocky intertidal species, L. saxatilis has likely had a long and continuous history in the Northwest Atlantic.
Genetics, Gene Flow, and Glaciation: The Case of the South American Limpet Nacella mytilina
TLDR
Historical and contemporary processes, contrasting glacial histories between the analyzed sectors, as well as life history traits constitute the main factors explaining the current biogeographical patterns of most shallow Patagonian marine benthic organisms.
Population structure in Arctic marine forests is shaped by diverse recolonisation pathways and far northern glacial refugia
TLDR
Examining marine refugial locations during the Last Glacial Maximum challenges the existing paradigm that marine Arctic ecosystems are depauperate extensions of southerly communities established in the wake of recent glaciation, fundamentally changing how these systems should be viewed and interpreted.
Phylogeography, historical demography and postglacial colonization routes of two amphi-Atlantic distributed amphipods
TLDR
The proposed postglacial colonization of America from Europe via the Faroe Islands, Iceland and Greenland could be more complex than previously thought and that parts of the North Atlantic region were not colonized from the Eastern Atlantic coasts.
Contemporary habitat discontinuity and historic glacial ice drive genetic divergence in Chilean kelp
TLDR
It is concluded that rafting facilitates colonisation of unoccupied shores, but has limited potential to enhance gene-flow among established populations, demonstrating that some taxa may be considered to have either high or low dispersal potential across different temporal and geographic scales.
Historical gene flow constraints in a northeastern Atlantic fish: phylogeography of the ballan wrasse Labrus bergylta across its distribution range
TLDR
The ballan wrasse (Labrus bergylta), the largest labrid fish along Europe's continental margins, is a target for fisheries and aquaculture industry and the existence of a marked population structure can reflect both recolonization from three distinct glacial refugia and current and past oceanographic circulation patterns.
Against all odds: a tale of marine range expansion with maintenance of extremely high genetic diversity
TLDR
Mitochondrial and nuclear markers revealed a striking high haplotypic nucleotide and genetic diversity values, along with significant population differentiation throughout the present-day geographical range of the Senegal seabream, not consistent with the central-marginal hypothesis, nor with the expectations of a leptokurtic distribution of individuals.

Surviving the ice: Northern refugia and postglacial colonization.
TLDR
Data from a deciduous forest vertebrate, the eastern chipmunk in the central U.S, is presented, indicating the maintenance of multiple refugial sources as well as a southward expansion from a northern refugium, challenging the view that, during glacial maxima, organisms must have migrated south out of their ranges to track favorable climates.
PHYLOGEOGRAPHY AND HISTORICAL ECOLOGY OF THE NORTH ATLANTIC INTERTIDAL
TLDR
The patterns of persistence in North America indicate that other life-history traits, including mechanisms of dispersal, may be more important for surviving dramatic environmental and climatic change.
Ice-age endurance: DNA evidence of a white spruce refugium in Alaska
TLDR
White spruce apparently survived long glacial episodes under climatic extremes in a heterogeneous landscape matrix, suggesting that estimated rates of tree migration from fossil records may be too high and that the ability of trees to track anthropogenic warming may be more limited than previously thought.
Glacial refugia and recolonization pathways in the brown seaweed Fucus serratus
TLDR
A generalized skyline plot suggested exponential population expansion beginning in the mid‐Pleistocene with maximal growth during the Eems interglacial 128 000–67 000 years ago, implying that the last glacial maximum mainly shaped population distributions rather than demography.

TLDR
DNA evidence indicates temperate species in Europe had different patterns of postglacial colonization across the same area and different ones in previous oscillations, whereas the northwest region of North America was colonized from the north, east and south.
Post-glacial re-colonization of European biota
TLDR
Diversity from southern to northern Europe in the extent of allelic variation and species subdivision is seen; this is attributed to rapid expansion northward and the varied topography of southern refugia allowing populations to diverge through several ice ages.
Strong genetic clines and geographical variation in gene flow in the rocky intertidal barnacle Balanus glandula
TLDR
This work examined the genetic continuity of the acorn barnacle Balanus glandula, an abundant member of rocky intertidal communities of the northeastern Pacific Ocean, and compared these genetic patterns to the nearshore oceanography described by trajectories of surface drifters.
Phylogeographic insights into cryptic glacial refugia.
TLDR
Many of the insights into the glacial histories of species in cryptic refugia gained through phylogeographic approaches are summarised.
Comparative phylogeography of two coastal polychaete tubeworms in the Northeast Atlantic supports shared history and vicariant events
TLDR
Signs of both persistence in small northern glacial refugia, and of northwards range expansion from regions situated closer to the Mediterranean are observed, however, whether the recolonization of the Northeast Atlantic by both species actually reflects separate interglacial periods is unclear with regards to the lack of molecular clock calibration in coastal polychaete species.
Glacial survival or tabula rasa? The history of North Atlantic biota revisited
TLDR
The evidence accumulated since the 1960s suggests, however, that endemism and disjunctions in the North Atlantic can be explained without invoking in situ glacial survival.
