It is argued that for marine organisms the genetic signatures of northern periglacial and southern refugia can be distinguished from one another, giving credence to recent climatic reconstructions with less extensive glaciation.

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.

The identification of a high genetic diversity hotspot in Northern Europe provides a basis for restoration decisions and links between historical and contemporary processes are discussed in terms of the projected effects of climate change on coastal marine plants.
Post‐ice age recolonization and differentiation of Fucus serratus L. (Phaeophyceae; Fucaceae) populations in Northern Europe
The seaweed Fucus serratus is hypothesized to have evolved in the North Atlantic and present populations are thought to reflect recolonization from a southern refugium since the last glacial maximum, whereas the Spanish populations most likely reflect present‐day edge populations that have undergone repeated bottlenecks as a consequence of thermally induced cycles of recolonized and extinction.
Real-time PCR reveals a high incidence of Symbiodinium clade D at low levels in four scleractinian corals across the Great Barrier Reef: implications for symbiont shuffling

Using a newly developed real-time PCR assay, this paper demonstrates that previous studies have underestimated the presence of background symbionts because of the low sensitivity of the techniques used, and indicates that the potential for symbiont shuffling may be much larger than currently thought.

Results from multidimensional scaling, amova and nested clade analysis indicate that British waters are a secondary contact zone recolonized from at least two refugia — one around the Iberian Peninsula and one possibly in the Azores.
The genome of the seagrass Zostera marina reveals angiosperm adaptation to the sea
The genome of Zostera marina, the first, to the authors' knowledge, marine angiosperm to be fully sequenced, reveals unique insights into the genomic losses and gains involved in achieving the structural and physiological adaptations required for its marine lifestyle.
The Roles and Interactions of Symbiont, Host and Environment in Defining Coral Fitness

These results highlight the complex interactions that occur between the coral host, the algal symbiont, and the environment to shape the fitness of the coral holobiont and will assist in predicting the responses of corals to global climate change.
Molecular genetic evidence for probable reticulate speciation in the coral genus Madracis from a Caribbean fringing reef slope
- O. Diekmann, R. Bak, W. Stam, J. Olsen

- 1 August 2001
Polymorphism parsimony of 89 sites, including nine that showed additivity, revealed a phylogenetic topology more consistent with inter-taxal hybridization in the decactis-formosa-pharensis cluster, and phylogenetic fission and fusion under Veron's model of reticulate speciation in corals is discussed.
