More than half of the endemics (50 species) have a restricted insular distribution; 31 of them are confined to a single island grouping and 19 only occur on two island groupings (Table 1).
Three particular endemics, Encyclia androsiana, Lepidium filicaule, and Matelea correllii, provide good examples of species whose distribution ranges are unknown.
Endemics may have the potential to act as indicators of ecosystem status for rapid assessment purposes.
A book that focuses on endemics must be cognizant of taxonomic status and recent splits and lumps.
The new Guide emphasizes the species endemic to individual islands or to the Greater Antilles and is directed at bird watchers in general as well as "listers" or "twitchers".
Overall this is a well thought out and well-constructed birding guide to a fascinating and accessible birding region with a high proportion of endemic species.
2008) and it is likely that some of the Caribbean endemics currently in these four genera will need new taxonomic placements (Michelangeli, pers.
Caribbean island endemics belonging to these polyphyletic genera are not placed in the clades that have their generitypes.
A full review concerning to what extent this phylogenetic pattern is followed by other endemics is outside the scope of this study; however, a review focusing on the endemic genera (Francisco-Ortega et al.
Meanwhile, the Catalina mahogany, right, is one of eight island endemics - plants found nowhere else in the world but here.
There are a handful of endemic mammals on Catalina, including the Island fox and Beechey ground squirrel, but sightings are infrequent.
It will help in identifying another island endemic, the Catalina live-forever, an aloelike succulent that can sometimes be spotted along the path.
Only three of the early branches of the family, Gochnatieae, Nassauvieae, and Mutisieae, have endemics in the region.
These low elevation areas were covered by the ocean approximately 125,000 years ago (Scott, 1997), and it is likely that many of the endemics from this region have a relatively recent origin.
Sunflower genera endemic to islands have provided outstanding examples of speciation through adaptive radiation (Adsersen, 1995; Givnish, 1998).
