Última Terrestrial and coastal landscape evolution on tropical oceanic islands Naturalis Viles, H.A.; Spencer, T.. Tropical oceanic islands owe their origin to volcanic eruptions, their location to plate tectonics, and their morphology to the interplay over time between a range of constructional and erosional processes. A broad distinction can be made between high volcanic islands, with summits up to 4,000 m, and low carbonate islands only a few metres above sea level.

Ano: 2011 URL: http://www.repository.naturalis.nl/record/428046 Miocene long-lived lake Pebas as a stage of mollusc radiations, with implications for landscape evolution in western Amazonia Naturalis Wesselingh, F.P.. The Miocene Pebas system was a huge (> 1 million km2) system of long-lived lakes and wetlands that occupied most of western Amazonia between c. 23 and 8 Ma. Remarkable endemic radiations of molluscs and ostracods occurred in the Pebas system. The continuity of many of the endemic lineages between c. 17 and 9 Ma shows that the system was never fully replaced by fluvial or marine settings. Many of the endemic invertebrate groups developed an unusual range of morphologies that reflect adaptation to specific ecological stresses provided by the Pebas system, such as chemical stress, common dysoxia and high predation pressure. Mollusc diversity increased especially during the Middle Miocene. The Pebas system provided pathways for mobile marine organisms to...
