In order to preserve biodiversity, we need to understand the mechanisms that sustain it. In their perspective, Taberlet and Cheddadi describe work (Tzedakiset al.) that illustrates the importance of southern refugia for the persistence of some temperate tree species during the last glacial-interglacial cycles. Interdisciplinary efforts to identify other putative refugia, could be important in long-term conservation planning. 

Multiple periglacial refugia in the Patagonian steppe and post‐glacial colonization of the Andes: the phylogeography of Calceolaria polyrhiza

Aim  We perform a phylogeographical study of an endemic Patagonian herbaceous plant to assess whether geographical patterns of genetic variation correspond to in situ Pleistocene survival or to

Biogeography and evolution of Abies (Pinaceae) in the Mediterranean Basin: the roles of long‐term climatic change and glacial refugia

Current knowledge concerning the origin and evolution of the genus Abies in the Mediterranean Basin are summarized and a comprehensive hypothesis to explain the isolation and speciation pattern of Mediterranean firs is proposed.

Refugia during the last glacial period and the origin of the disjunct distribution of an insular plant

Although many phylogeographic studies have focused on continental refugia, the roles of islands as refugia have long been overlooked. In this study, we conducted phylogeographic studies of a plant

Climate change and evolution of the New World pitviper genus Agkistrodon (Viperidae)

This work derived phylogenies, phylogeographies, and population demographies for two North American pitvipers, Agkistrodon contortrix and A. piscivorus, as a mechanism to evaluate the impact of rapid climatic change on these taxa.

Patterns of freshwater biodiversity in Europe: lessons from the spring snail genus Bythinella

Patterns of biodiversity in the spring snail genus Bythinella, a group of highly isolated and stenotopic freshwater species, are analyzed to test whether there are European areas of increased diversity and whether these hotspots match the Pleistocene refugia of ByThinella spp.

Endemism and Tertiary Relict Forests

Among China’s various regions, the SW harbors the greatest number of endemic plant species. Among them, some taxa from the Tertiary Period, such as the relict maidenhair tree (Ginkgo biloba), the

Refugia: identifying and understanding safe havens for biodiversity under climate change

Aim  Identifying and protecting refugia is a priority for conservation under projected anthropogenic climate change, because of their demonstrated ability to facilitate the survival of biota under

Break zones in the distributions of alleles and species in alpine plants

Aim  We test for the congruence between allele‐based range boundaries (break zones) in silicicolous alpine plants and species‐based break zones in the silicicolous flora of the European Alps. We also

Characteristics of climate change refugia for Australian biodiversity

Identifying refugia is a critical component of effective conservation of biodiversity under anthropogenic climate change. However, despite a surge in conceptual and practical interest, identifying

1.36 million years of Mediterranean forest refugium dynamics in response to glacial–interglacial cycle strength

Assessment of long-term legacy effects between global climate and regional vegetation change reveals a significant influence of cool interglacial conditions on subsequent glacial vegetation composition and diversity, contrary to observations at high latitudes.

Constancy of species and communities of species can be demonstrated to be the norm for at least the last million or so years (= generations), and the enigma of how such constancy was sustained in the face of large-scale climatic fluctuations remains a puzzle.

The results show that LGM ice volume was approximately 35 percent lower than suggested by the CLIMAP reconstruction and the maximum heights of the main Laurentian and Fennoscandian ice complexes are inferred to have been commensurately lower with respect to sea level.
