I re‐evaluate the specific biogeographical significance of each of the land bridges (Beringia, Thulean and De Geer) in the Northern Hemisphere during the latest Cretaceous–early Cenozoic, showing that the Thulean and De Geer routes did not operate contemporaneously. 

Vicariance versus dispersal across Beringian land bridges to explain circumpolar distribution: A case study in plants with high dispersal potential

To disentangle the importance of the Beringian land bridges during the Pliocene and Quaternary periods in order to explain the current distribution of circumpolar plants with potential for

In and out of the Qinghai‐Tibet Plateau: divergence time estimation and historical biogeography of the large arctic‐alpine genus Saxifraga L.

The biogeographical history of the large genus Saxifraga is studied to unravel the role played by the Qinghai‐Tibet Plateau for the diversification of this genus and to understand factors that have led to the establishment of high biodiversity in and around this region.

How did subterranean amphipods cross the Adriatic Sea? Phylogenetic evidence for dispersal–vicariance interplay mediated by marine regression–transgression cycles

Freshwater subterranean amphipods with low dispersal abilities are known from both sides of the impermeable barrier, the Adriatic Sea. We tested the hypothesis that historical marine

Late Cretaceous–Early Eocene origin of yams (Dioscorea, Dioscoreaceae) in the Laurasian Palaearctic and their subsequent Oligocene–Miocene diversification

Fossil records from both the Northern and Southern Hemispheres were used to test hypotheses about the origin of the genus Dioscorea, and to examine potential macroevolutionary processes that led to its current distribution.

The roles of dispersal and mass extinction in shaping palm diversity across the Caribbean

The rich flora of the Caribbean islands and surrounding mainland evolved in a context of isolation alternated with phases of terrestrial connectivity between landmasses, climatic fluctuations and

Land connectivity changes and global cooling shaped the colonization history and diversification of New World quail (Aves: Galliformes: Odontophoridae)

This work reconstructed colonization history and diversification of odontophorids with respect to hypothesized dry‐land connections between continents (North Atlantic, Beringian, Panamanian) that would have facilitated faunal exchange.

The second North American fossil horntail wood-wasp (Hymenoptera: Siricidae), from the early Eocene Green River Formation.

The Eocene forest that Eoteredon inhabited had a mesothermal to megathermal climate and is proposed as sister to the genus Teredon, whose sole species is one of the rarest of extant Siricidae.

An ancient tropical origin, dispersals via land bridges and Miocene diversification explain the subcosmopolitan disjunctions of the liverwort genus Lejeunea

This study shows that an ancient origin associated with a dispersal history facilitated by terrestrial land bridges and not long-distance dispersals are likely to explain the subcosmopolitan distribution of Lejeunea and monoicy likely favoured the colonisations of new areas, especially in the Miocene that was a key epoch shaping the worldwide distribution.

Biogeography of Neotropical Meliaceae: geological connections, fossil and molecular evidence revisited

We here provide, first, a general introduction into the woody angiosperm family Meliaceae, including updated numbers of the genera and species found in different parts of the globe, paying attention

An Estimate of the Early Tertiary Paleoclimate of the Southern Arctic

The early Tertiary southern Arctic was an important biogeographic exchange route between the Old and New Worlds. A variant of the nearest living relative method of paleoclimatic estimation suggests

New Early Carnivoran Specimens from the Puercan (Earliest Paleocene) of Saskatchewan, Canada

Abstract New specimens of an as yet unidentified carnivoran from the earliest Paleocene of Saskatchewan are described. The new specimens augment the evidence on which the contentious earliest (middle

Abstract Problems of resolution and poor superpositional evidence in mammalian biostratigraphy through Paleocene-Eocene boundary strata in NW Europe are solved by applying parsimony analysis to taxa

The last polar dinosaurs: high diversity of latest Cretaceous arctic dinosaurs in Russia

Dinosaur eggshell fragments indicate that at least several latest Cretaceous dinosaur taxa could reproduce in polar region and were probably year-round residents of high latitudes, strongly questions hypotheses according to which dinosaur extinction was a result of temperature decline, caused or not by the Chicxulub impact.

The TRANSMED Transects in Space and Time: Constraints on the Paleotectonic Evolution of the Mediterranean Domain

The Phanerozoic evolution of the western Tethyan region was dominated by terrane collisions and accretions, during the Variscan, Cimmerian and Alpine cycles. Most terranes were derived from Gondwana

Paleocene Tracks of the Mammal Pantodont Genus Titanoides in Coal-Bearing Strata, Svalbard, Arctic Norway

ABSTRACT We discuss large tracks recently discovered in Paleocene coal deposits from Svalbard. The age, large size, and excellent preservation of the tracks allows them to be identified to the

Floras characterizing comparable evolutionary stages in the Anadyr-Koryak and North Alaska subregions of the North Pacific show some essential distinctions despite their similarity in general.

Paleogene floral assemblages around epicontinental seas and straits in Northern Central Eurasia: proxies for climatic and paleogeographic evolution

Paleogene connection of Tethyan and Paleoarctic water masses and biotas was largely enhanced by a N-S trending epicontinental seaway in northern Central Eurasia, which extended from the Aral Sea to

Glires (Mammalia) from the Late Paleocene Bayan Ulan Locality of Inner Mongolia

Abstract Two new early diverging members of Glires, Eomylus bayanulanensis, n.sp. and Palaeomylus lii, n.gen. and n.sp., are described from the late Paleocene Bayan Ulan Fauna, Inner Mongolia, China.
