Three islands, three worlds: paleogeography and evolution of the vertebrate fauna from the Balearic Islands

The Balearic Islands are an archipelago located in the Western Mediterranean Sea. Their isolation from the mainland allowed the establishment of different faunas on each of them. While in Mallorca the Pliocene fauna was composed of the so called Myotragus-fauna (mainly consisting of a bovid, a glirid and a soricid), in Menorca it was constituted by the giant rabbit-fauna (mainly consisting of a...

Toxins Found in Ciguatqxic Fishes in the Ryukyu Islands

TOXINS FOUND IN CIGUATOXIC FISHES IN THE RYUKYU ISLANDS by Yoshiro HASHIMOTO * Evidence for multiplicity of toxin involved in ciguatera has been increasingly accumulated. At least four different toxins have been demonstrated in ciguatoxic fishes in the Ryukyu Islands. The fat-soluble toxin probably identical with ciguatoxin was found in the muscle of Lut/janus bohar and L. monostiqma. This toxi...

Insular mammalian fauna dynamics and paleogeography: A lesson from the Western Mediterranean islands

Since the time of Darwin (1859) and Wallace (1869), islands have been regarded by scientists as a prime target for scrutinizing the forces that may influence evolution and diversification and important elements in biogeographic studies. This research aims to scrutinize whether and to what extent the composition and structure of past mammal insular faunas and their changes through time may provi...

Two new dwarfgobies of the genus Eviota from the Ryukyu Islands, Japan (Teleostei: Gobiidae).

Two species of dwarfgoby are described from the Ryukyu Islands, Japan. Eviota flebilis n. sp. belongs to cephalic sensory-pore system pattern 2 (lacking only IT pore), has a dorsal/anal fin-ray formula of 8/7, unbranched pectoral-fin rays, the 5th pelvic-fin ray 12.9% of the 4th, a distinctive narrow, red-orange line under the eye, and a dark vertical line at the caudal-fin base. Eviota specca ...
