The Migration of the Palaeotropical Arid Flora: Zygophylloideae as an Example

  author={Dirk U. Bellstedt and Chlo{\'e} Galley and Michael D Pirie and Hans Peter Linder},
Abstract The rate and direction of biotic exchange between the Palaeotropical arid floras of Asia, Africa, and Australia is poorly understood because of a lack of phylogenetic hypotheses for relevant plant groups. Periodic aridification may have facilitated migrations of arid-adapted plants between southwestern Africa and the Horn of Africa as recently as the last glacial maximum, allowing further exchange with the arid floras of Asia. However, no conclusive evidence of the age and direction of… 

Living on the edge: timing of Rand Flora disjunctions congruent with ongoing aridification in Africa

The Rand Flora pattern seems to fit the definition of biogeographic pseudocongruence, with the pattern arising at different times in response to the increasing aridity of the African continent, with interspersed periods of humidity allowing range expansions.

Evolution of Asian Interior Arid-Zone Biota: Evidence from the Diversification of Asian Zygophyllum (Zygophyllaceae)

A multi-stage evolution model for this biota is proposed: the late Eocene–early Oligocene origin, the early Miocene expansion, and the middle-late Miocene rapid expansion to the whole Asian interior arid zone.

Opposite trends in the genus Monsonia (Geraniaceae): specialization in the African deserts and range expansions throughout eastern Africa

The results indicate that Monsonia first diversified in the Early Miocene c.21 Ma, coinciding with the start of desertification in southwestern Africa, and an important diversification occurred c. 4–6‬Ma, after a general cooling trend in western South Africa and the rising of the Eastern African Mountains.

Insights into the historical assembly of global dryland floras: the diversification of Zygophyllaceae

The results suggest that the rise of global dryland floras is near-synchronous and began at the mid-late Miocene, possibly resulting from the mid -Miocene global cooling and regional orogenetic and climate changes.

It is argued that six floras, with distinct geographical centres, different extra-African affinities, ages of radiation and radiation rates, can be delimited: the Austro-temperate, Tropic-alpine, Lowland forest,tropic-montane, Savanna and Arid Floras.

Out of Africa: Miocene dispersal, vicariance, and extinction within Hyacinthaceae subfamily Urgineoideae.

The flattened winged seeds of Urgineoideae could have played an important role in long-distance dispersal by strong winds and big storms, whereas geodispersal could have also occurred from Southern Africa to Asia and the Mediterranean region via the so-called arid and high-altitude corridors.

A phylogeny of the genus Chamaeleo with investigation of cryptic speciation

The aims of the present study were to reconstruct the ancestral 1081 biogeographic history of the genus Chamaeleo and to investigate whether there is evidence for niche partitioning between the three cryptic species within the C. dilepis complex.



The Cape element in the Afrotemperate flora: from Cape to Cairo?

This work reconstructs the historical biogeography of the four lineages of Disa, Irideae p.p., the Pentaschistis clade and Restionaceae, and finds that tropical taxa are nested within a predominantly Cape clade.

Cape diversification and repeated out-of-southern-Africa dispersal in paper daisies (Asteraceae-Gnaphalieae).

Old-New World and trans-African disjunctions of Thamnosma (Rutaceae): intercontinental long-distance dispersal and local differentiation in the succulent biome.

It is concluded that the Old-New World disjunction of Thamnosma is likely the result of long-distance dispersal, thus making a vicariance explanation feasible.

Floristic biodiversity and history of African arid regions

The phytochorological patterns of the arid flora of Africa are discussed on various levels. The arid regions of the African continent are linked by a large number of taxa with disjunct distribution.

Bayesian island biogeography in a continental setting: the Rand Flora case

The use of a Bayesian approach to island biogeography for disentangling the evolutionary origins of a continental-scale floristic pattern, the enigmatic ‘Rand Flora’, indicates that there has been little exchange between southern Africa and the northern African region, and that this exchange occurred via east Africa.

Phylogeny and historical biogeography of African ground squirrels: the role of climate change in the evolution of Xerus

The inferred phylogeny supports the hypothesized existence of an ‘arid corridor’ from the Horn of Africa to the Cape region and allopatric fragmentation as the cause of the deep divergences within this species.
