Hence an oceanic island
at first sight seems to have been highly favourable for the production of new species.
The volcanic nature of these oceanic islands
is evidently an extension of that law, and the effect of those same causes, whether chemical or mechanical, from which it results that a vast majority of the volcanoes now in action stand either near sea-coasts or as islands in the midst of the sea.
Sipadan Island, the only oceanic island
in Malaysia, forming a beautiful atoll secluding and protecting its sea animals and fish.
Raptors have key roles in the food web of oceanic island
ecosystems given the virtual absence of native mammalian predators (Losos and Ricklefs 2009).
Sipadan is the only oceanic island
in Malaysia; it is not attached to the continental shelf and stands on a limestone and coral stalk, rising 600 metres from the bed of the Celebes Sea.
Other topics of the 21 papers include the formation of Martian river valleys by impacts, oceanic island
basalts and mantle plumes, frictional melting processes in planetary materials, spatial patterns in isotopic biogeochemistry, and glacial earthquakes in Greenland and Antarctica.
Many anecdotal accounts exist of large crocodiles being sighted far out to sea, but this is the first study to show - using underwater acoustic tags and satellite tracking - that estuarine crocodiles ride surface currents during long-distance travel, which would enable them to voyage from one oceanic island
Thus, oceanic island
basalts (OIBs) provide important chemical evidence regarding mantle composition, magma formation processes and magma evolution.
A third to a half of all oceanic island
species were likely to be extinct or on the brink of extinction by 2100.
The results of this investigation suggest that the dodo fossil sanctuary at Mare aux Songes is among the world's richest oceanic island
fossil depositories and, being only several thousands years old, is the youngest fossil undisturbed ecosystem in the world.
161), oceanic island
basalts (OIB) provide insights into mande composition, magma formation processes and magma evolution (Fig.
Biological invasions are causing severe problems worldwide, but oceanic island
ecosystems are exceptionally vulnerable to invading weeds and animals.
