Flora of Jahanbin Mountain Area: A Contribution to Flora of the Central Zagros Region of Iran

Flora of Jahanbin mountain area in Chaharmahal and Bakhtiari province, located between Shahrekord and Hafshejan cities, with 12’187 hectares and 2’150 to 3’300 m elevation above sea level, is investigated. Vegetation of this area comprises of 273 species, 189 genera and 42 families. Asteraceae (37 species, 13.5%), Poaceae (31 species, 11.3%) and Fabaceae (25 species, 9.1%) were the most importa...

Mammalian dispersal at the Paleocene/Eocene boundary.

A profound faunal reorganization occurred near the Paleocene/Eocene boundary, when several groups of mammals abruptly appeared on the Holarctic continents. To test the hypothesis that this event featured the dispersal of groups from Asia to North America and Europe, we used isotope stratigraphy, magnetostratigraphy, and quantitative biochronology to constrain the relative age of important Asian...

Fossil Araceae from a Paleocene neotropical rainforest in Colombia.

Both the fossil record and molecular data support a long evolutionary history for the Araceae. Although the family is diverse in tropical America today, most araceous fossils, however, have been recorded from middle and high latitudes. Here, we report fossil leaves of Araceae from the middle-late Paleocene of northern Colombia, and review fossil araceous pollen grains from the same interval. Tw...
