Introduction to Continental Island

If so, its usefulness as a model system to study evolution would have been limited since the biota of continental islands (e.

Among island colonists, selfing ability did not differ between species on oceanic and on continental islands or between species native to islands and naturalized on islands.

The tectonic setting discrimination diagrams signify that the parent rocks of sandstones in the western and southern Ordos Basin were mainly developed from continental island arc, which is closely related to the evolution of the QinlingQilian Orogenic Belt.

There was however a clear distinction between oceanic and continental islands: a stable climate in the latters was key to the survival of the original biota leading to a high proportion of shared lineages between the mainland and islands.

Bryophytes of continental islands have received little attention in biogeography.

The Ryukyu Archipelago, located at the southwestern part of Japan, is known as a group of continental islands and harbours many endemic taxa, supposedly reflecting its fairly long isolation from the Eurasian continent, Taiwan and the Japanese main islands.

Trace element chemistry, although scattered towards the continental island arc fields on some geochemical diagrams (e.

The bromeliad-frog Phyllodytes luteolus inhabits tank bromeliads in sandy coastal plains and lowland forests on the mainland, as well as a continental island in southeastern Brazil.

The results based on the synthesis of petrology, geochemistry, and regional tectonic background studies show that 1) the andesitic magma source in the study area is an enriched mantle, which is modified by subduction zone fluids; 2) the geotectonic background environment of the andesite in Sayaburi area is the continental island arc environment and related to the tectonic evolution of Jinghong-Nan-Uttaradit back-arc basin, which reflects that the magmatic source is enriched with a mantle wedge component modified by a subduction zone fluid (or melt).

We investigated causes of local tropical forest tree community assembly on a continental island with heterogeneous terrain.

The protoliths of amphibolites were calc-alkaline basalt to andesite, which formed in a continental island arc setting.

By contrast, birds on continental islands share long coevolutionary histories with both Plasmodium and Haemoproteus, and are thus ideal model systems to elucidate eco-evolutionary endpoints associated with these parasites in oceanic islands.

In the case of the TPP section, the continental margin, as well as the partly the continental island arc, are recorded in the detritus, predominantly derived from older, continental sedimentary-metasedimentary terrains.

Plots of K2O/Na2O-SiO2, SiO2/Al2O3-K2O/Na2O, La-Th-Sc, Th-Sc-Zr/10 and Th-Co-Zr/10 indicate a tectonic setting of oceanic island arc or continental island arc.

Continental islands are useful models to explore the roles of shared historical factors in the evolution of sympatric species.

As a result of major and trace-element tectonic setting discrimination diagrams and geochemical parameters, sedimentation in the studied area was likely to occur at the Continental Island Arc (CIA) setting under a well- oxygenated condition.

, La/Yb versus ΣREE, ΣREE versus SiO2/Al2O3, La/Th versus Hf and function discrimination diagrams) reveal that sandstones from the Weimei Formation were derived from ancient quartzose sedimentary rocks and volcanic rocks of continental island arc.

These results support the hypothesis that the tectonic background of the southern Lhasa subterrane was an oceanic island-arc setting, rather than a continental island-arc setting, during the Late Triassic – Jurassic period.

The new species was recorded both on the mainland, at the municipality of Itaguaí and Rio de Janeiro, and at the continental island of Ilha Grande, in Angra dos Reis, at the Rio de Janeiro State.

The GBR encompasses a vast array of unique and important marine and terrestrial habitats, from deepwater reefs to archetypal barrier reefs, as well as vast seagrass and algal meadows, intertidal mud flats, sand cays, and continental islands.

Volcanic or microcontinental islands are larger, older, and reach high elevations; they have a high species diversity except for three sub-Antarctic islands.

The provenance of the Malanggou Formation was in a continental island arc setting.

In view of the representative and environment-sensitive indices, we suggest that passive continental margin and continental island arc dominated by granite to granodiorite source are the major tectonic settings of the provenance, and both a more warm-humid climate characterized by intensified chemical weathering conditions and a calm tectonically quiescent setting are identified as two major drivers forcing the accumulation and preservation of organic matter in organic-rich continental shale units.

Few attempts have been made to assess the comparative contributions of different environmental factors on species composition (SC) and richness (SR) of bryophytes on continental islands.

We reinvestigated the bryophyte biodiversity of Hainan Island, a continental island off the south China coast, with an extensive literature survey focusing on specimen information, and additional field collections.
