Protected Areas and Endemic Species
... In general, there are two major factors influencing the degree of endemism in an area: isolation and stability. Thus isolated islands and mountains are often rich in endemics. Long-term climatic stability is rather rare, but there is evidence that some parts of the planet have been more stable than ...

The Floating Islands of Lake Dupuis
... The floating islands of Lake Dupuis are a special case. They play an important ecological role. As mentioned above, a part of the bank was flooded when the water level of Lake Masson raised. The vegetation had not been removed prior to the flooding. By the end of the 50’s, all bays had been cleaned ...

Mascarene Islands
The Mascarene Islands (or Mascarenhas Archipelago) is a group of islands in the Indian Ocean east of Madagascar consisting of Mauritius, Réunion and Rodrigues. The collective title is derived from the Portuguese navigator Pedro Mascarenhas, who first visited them in the early sixteenth century. The islands share a common geologic origin in the volcanism of the Réunion hotspot beneath the Mascarene Plateau and form a distinct ecoregion with a unique flora and fauna.
