“…These divergence events were concordant with the narrowing of the Tethyan Seaway (50–18 Ma), suggesting that it was a driver of divergence events shaping current distributions of tropical brittle stars (except Ophiodermatidae). Although the splits pre‐dated the TTE, our results are congruent with previous findings in other marine taxa (reviewed in Hou & Li, ), for which pre‐TTE vicariance has been explained by the emergence of genetic barriers driven by ecological changes resulting from plate tectonics (Liu, Li, Ugolini, Momtazi, & Hou, ). Apparent vicariant events pre‐dating the TTE have also been attributed to calibration errors (Malaquias & Reid, ) or selective extinction concealing patterns (Cowman & Bellwood, ).…”

Aim Biogeographic barriers emerged in the tropical oceans as continental masses moved with plate tectonics, and as the tropics contracted to lower latitudes from the late Eocene. These barriers have shaped tropical marine biodiversity. We characterize large‐scale diversity patterns for tropical brittle stars and investigate the effect of biogeographic barriers on these in space and time. Location Shallow‐water (<200 m) tropical oceans. Taxon Tropical shallow‐water brittle stars (class Ophiuroidea). Methods We integrate phylogenetic and biogeographic modelling to test and quantify the biogeographic structuring across the major ocean basins for five families of brittle stars. These are well‐sampled in our phylogenies (173 species) and represent an important component of the brittle star fauna of tropical shallow waters. We define major bioregions based on patterns of compositional and phylogenetic beta diversity. Results We find congruence between patterns of shared ancestry of regions and inferred biogeographic histories. Biogeographic reconstructions show that faunal patterns reflect the emergence of biogeographic barriers in the tropical world, with evidence of vicariant events driven by the opening of the Atlantic Ocean, the narrowing of the Tethyan Seaway and the rise of the Isthmus of Panama. Main conclusions Biogeographic barriers almost completely isolated regional faunas. However, divergence age estimates predate the onset of the different barriers, suggesting that changes associated with the gradual emergence of the barriers had a strong effect on the evolutionary history of tropical shallow‐water brittle stars. Limited, very recent, bi‐directional dispersal was detected across the East Pacific Barrier, which is otherwise an important barrier for dispersal of brittle stars.

“…Many subtropical plant and animal lineages exhibit a disjunct distribution in the pan‐Mediterranean and East Asia (Valcarcel, Guzman, Medina, Vargas, & Wen, ; Velitzelos, Bouchal, & Denk, ). This East Asian‐Tethyan disjunction is one of several so‐called “Tethyan disjunctions,” a suite of disjunct patterns among Mediterranean Europe, North Africa, and East Asia that have been reported in a wide range of taxa (e.g., Xie, Yang, Wen, Li, & Yi, ; Wei et al, ; Liu et al, ). The cause of these disjunctions is not fully understood (Milne, ).…”

Aim Many subtropical organisms exhibit an East Asian‐Tethyan disjunction, a distribution split between East Asia and the Mediterranean. The underlying mechanisms and timing have remained unclear to date. The evolutionary history of Quercus section Ilex Loudon, a representative East Asian‐Tethyan disjunct lineage with a rich and widespread fossil record, was investigated to understand the key drivers of this disjunction. Location Eurasia. Methods The phylogeny of Quercus section Ilex was reconstructed using RAD‐seq. Divergence times were estimated based on three fossil calibrations. Ancestral range and niche were reconstructed on the calibrated tree to infer the timing of transitions in geographic distributions and niche. Convergence in ecological space was estimated by fitting alternative multiple‐regime Ornstein‐Uhlenbeck models. Leaf shape affinities among extant and fossil taxa of section Ilex were assessed using geometric morphometric approaches. Results Six clades were well resolved in section Ilex. Ancestral range reconstruction and divergence time dating suggest a wide distribution along the East Tethys seaway, with initial divergence at the mid‐Eocene, and all six clades originating before the Miocene. The section dispersed from East Asia to the Mediterranean at the Eocene‐Oligocene boundary. A shift toward higher elevations was detected in the Himalayan clade during the middle or late Miocene. European fossil lineages during the early Miocene differ in leaf morphology from later lineages, which we infer to be a consequence of adaptive differentiation or species turnover. Main conclusions Quercus section Ilex was widespread along the East Tethys seaway from the middle Eocene onward. The European holly oaks originated from an East Asian ancestral lineage that dispersed to Europe via the Tibet‐Himalaya corridor in the Oligocene. Lowlands along the margins of the Himalayas and through an Oligocene Tibetan valley served as the dispersal route(s) for these species. Changing climates drove Miocene extinction and local adaptation of European lineages.

“…The Tethyan tropical peak of diversity was displaced eastwardly over time to its current location in the CT (Renema et al, ). The closure of the Tethyan Seaway during the so‐called Terminal Tethyan Event (TTE) during the Early to Middle Miocene (14–18 Ma) drove isolation, allopatric fragmentation and diversification of local faunas (Hou & Li, ; Liu, Li, Ugolini, Momtazi, & Hou, ; Malaquias & Reid, ). More recently, the complete uplifting of the Isthmus of Panama (IOP) during the Pliocene has interrupted connectivity between the Atlantic and the Indo‐Pacific oceans through the Central American Seaway (∼3 Ma) (O'Dea et al, ).…”

Deep‐sea squat lobster biogeography (Munidopsidae: Leiogalathea) unveils Tethyan vicariance and evolutionary patterns shared by shallow‐water relatives

The ecology, abundance and diversity of galatheoid squat lobsters make them an ideal group to study deep-sea diversification processes. Here, we reconstructed the evolutionary and biogeographic history of Leiogalathea, a genus of circum-tropical deep-sea squat lobsters, in order to compare patterns and processes that have affected shallow-water and deep-sea squat lobster species. We first built a multilocus phylogeny and a calibrated species tree with a relaxed clock using StarBEAST2 to reconstruct evolutionary relationships and divergence times among Leiogalathea species. We used BioGeoBEARS and a DEC model, implemented in RevBayes, to reconstruct ancestral distribution ranges and the biogeographic history of the genus.Our results showed that Leiogalathea is monophyletic and comprises four main lineages; morphological homogeneity is common within and between clades, except in one; the reconstructed ancestral range of the genus is in the Atlantic and Indian oceans (Tethys). They also revealed the divergence of the Atlantic species around 25 million years ago (Ma), intense cladogenesis 15-25 Ma and low levels of speciation over the last 5 million years (Myr). The four Leiogalathea lineages showed similar patterns of speciation: allopatric speciation followed by range expansion and subsequent stasis. Leiogalathea started diversifying during the Oligocene, likely in the Tethyan. The Atlantic lineage then split from its Indo-Pacific sister group due to vicariance driven by closure of the Tethys Seaway. The Atlantic lineage is less speciose compared with the Indo-Pacific lineages, with the Tropical Southwestern Pacific being the current centre of diversity. Leiogalathea diversification coincided with cladogenetic peaks in shallow-water genera, indicating that historical biogeographic events similarly shaped the diversification and distribution of both deep-sea and shallow-water squat lobsters.
